(54) METHOD OF THE SEPARATION OF A PERFECTLY SOLDED LOCK

(57) Summary:

In a method for the removal of solids from the excess of sputter formed during the dyeing of objects, excess spraying is captured by the flow of air and transported separating surface (42a, 42b, 142a, 142b) where the majority of at least solids passes into the separation liquid, the deposition is removed from the liquid. A separating liquid that contains a decontamination medium or a decolourising medium and a carrier fluid is used and described, while the particles of excessively sprayed varnish are glued off with the adhesive medium, while the separation fluid is electrically conductive, and the excessively sprayed lacquer is ionized with the aid of the electrode device (56, 156) and separated into a separation surface (42a, 42b, 142a, 142b), with the electrode device (56, 156) having '

The invention relates to a method of removing solids from the spray-forming objects formed during the coloring of spray objects, in which excess spraying is carried away by air flow, is transported to a separating surface washed with a separating fluid, where most of at least solids pass into the separating liquid, is discharged, and the placement is removed from liquids

In addition, the invention relates to a separation liquid for the removal of solids arising from the spraying of spray objects.

When manual or automatic application of varnishes on objects a partial flow of varnish, which generally contains both solids, and solvents and / or binders, is not applied to the object. Among the experts, this partial flow is called "excess spraying". Excessive sintering is carried away by airflow in the spray chamber and fed to the separation.

First of all, in installations with a relatively large expense of varnish, for example, installationssurgery of car bodies, mainly used systems of wet separation, which uses the methods specified in the beginning of the species. In the plants known in the market as a separation liquid, water or oil is used, which swirks intensively from the air chambers and the excess spray that is in it.

In order to be absorbed by separating liquid particles of varnish could be flawlessly removed from the separation surface, the separation liquid must meet specific criteria. For example, the fact that the gluing action of the lacquer particles should be removed so that they, if they are in contact with the separation surface through the separating fluid, do not stick with it.

In addition, the pressure of the separation liquid vapor should be, at least, so low that the seizure of the gaseous components of the separation fluid by the air passing through the camera was minimized.

In order to ensure as uniformly as possible, as well as free from influences and tides, the lubrication of the separation surface, the surface tension of the separation fluid should be rather low.

First of all, it is desirable that the separation fluid could drain from the separation surface to a considerable extent laminar, that is, to create a thin film on the separation surface that evenly moves downwards.

Therefore, it is an object of the invention to provide a method and a separation fluid specified in the beginning of the invention, which take into account the above-stated idea and provide for efficient removal of excess air spray from the chamber with a separation liquid.

With respect to the method, said task is solved by the use of a separation liquid containing a decontamination medium and, if necessary, a carrier fluid, in which a fraction of the excessively sprayed varnish is glued off by a biodegradable medium.

Glutening particles of a super-sprayed varnish can be accomplished by means of an adhesive-free agglomeration medium of particles of excessively spray lacquer / or by solidifying a super-sprayed varnish that occurs or accelerates due to the adhesive medium, and / or by eliminating under known circumstances an existing emulsion that is effected by a biodegradable medium.

Thus, according to the invention, the adhesive properties of excess sputter are largely shifted, so that the risk of adhesion of excess spraying with the separation surface is reduced.

It turned out to be favorable if the decaying medium is a biodegradable medium on the basis of silicates, mainly layered silicates, bentonites, sepilolites, alumina; on the basis of aluminum salts, predominantly aluminum salts, which, with neutral and alkaline hydrogen indicators, form hydroxides, preferably aluminum sulphate, aluminum chloride, aluminum nitrate; on the basis of zinc salts, mainly zinc salts, which, with neutral and alkaline hydrogen indicators, form hydroxides, mainly zinc chloride, zinc sulfate; on the basis of iron salts, mainly iron salts, which, in the case of neutral and alkaline hydrogen, form hydroxides, predominantly iron chloride, iron sulfate; based on calcium salts, mainly calcium chloride, calcium nitrate, calcium acetate; based on zirconium salts, preferably zirconium chloride, zirconium acetate; on the basis of polymers, preferably polyacrylamides, polymethacrylamides, or condensation products of melamine / formaldehyde; or on the basis of amines, preferably diamines, preferably 2-methylpentamethylenediamine, ethylenediamine.

Depending on whether the separable excess spray on the solvent is based on a water-soluble varnish or solvent-based varnish, these release agents act as an agglomeration means, as accelerators for solidification or as substances that split emulsions.

With the help of separating liquids containing a decontamination medium in an amount from 0.1 to 20 wt. %, preferably from 1 to 5% by weight. %, based on the total mass of the separation fluid, were obtainedgood results.

It is beneficial if water is used as a carrier liquid.

In the case of a water-based separation liquid, it has been found to be advantageous if it also contains one or more polar, water soluble solvents, preferably ethylene glycol, propylene glycol, polyethylene glycol or polypropylene glycol. Such solvents act as intermediates of dissolution, and facilitate the absorption of excessively spray gunpartition liquid.

In this case, first of all, it turned out to be favorable if the separation liquid contains a polar, water soluble solvent in an amount from 1 to 60 wt. %, preferably from 20 to 40% by weight. %, based on the total mass of the separation fluid.

Absorption of particles of excessively sprayed varnish in the case of a water-based separation liquid has been improved if it also contained one or multiple lubricants, preferably nonionic, anionic or cationic surfactants, especially nonionic surfactants, preferably ethoxy silicates row, proxilate the fatty alcohol.

In this case, it is advantageous if the separation fluid contains a wetting agent in an amount from 0.1 to 5 wt. % of the total mass of the separation fluid. With the help of pulp substances, the surface tension of the separation fluid can be regulated and its adhesiveness and fluidity on the separation surface.

A water-based separation fluid with a higher viscosity may be obtained if the tread contains, moreover, thickeners, preferably cellulose, carboxymethylcellulose, methyl ethyl cellulose, hydroxypropyl cellulose, hydroxypropylethyl cellulose, polysaccharides, gum arabic, xanthan or modified starch, especially preferably carboxymethylcellulose. This is advantageous if the separation liquid contains thickener in an amount from 0.1 to 5 wt. %, preferably 0.1 to 1 wt. % of the total mass of separation liquids.

Separation viscous liquid flows more slowly, so that a certain amount of separation ridynydovshe is in contact with the air chamber containing excess spray and mozhepohlynaty larger share of the excess spray, the same amount ridynnotekuchoyi separatsiynoyiridyny.

In order to increase the stability during storage of a water-based separation liquid, it is advantageous if it also contains preservatives, preferably isothiazolines; quaternary ammonium compounds, preferably dedecyl dinamonic chloride, dioctyl dyomonic acid, dimethyldimethylhydantoin; bromochloromethylhydantoin or bisoxazolidine; preferably in the range of 0.5 to 10 wt. % of the total mass of the separation fluid.

In the case of an alternative separation fluid, it is beneficial if the oil serves as the carrier fluid. The term "oil" refers to all oil liquids whose viscosity isfirst higher than the viscosity of water. Suitable, for example, paraffin or naphthenic refinants. Other suitable oils are, for example, ground oils, rapeseed oil or palm oil. The oils initially give such beneficial properties as higher viscosity and insignificant surface tension, through which they are well suited as a liquid. bearer

It turned out to be useful if a separation liquid based on oil, in addition, contains stabilizing agents, preferably in the form of organic acids, preferably in the form of fatty acids, especially in the form of oleic acid, palmitic acid, stearic acid or hydroxystearic acid, in an amount of from 0.1 to 15 wt % of the total mass of separation fluid.

If a paste separating liquid has to be produced, it would be advantageous if it also contains fatty acid in an amount from 1 to 30% by weight. %, preferably from 3 to 20% by weight. % of the total mass of the separation liquid, preferably oleic acid or stearic acid.

In this case, it is advantageous if the separation liquid also contains hydroxydemetal, preferably sodium hydroxide, potassium hydroxide or lithium hydroxide, in an amount of from 1 to 5 wt. % of the total mass of the separation fluid.

It is favorable if the viscosity of the separation fluid, measured by the drainage reservoir, is in accordance with DINN EIN 8802431, the German version of EODI8O 2431: 1996, 1996, with drain holes with a diameter of 6 mm, is from 2 to 100 seconds, preferably from 5 to 20 seconds and especially 10.5 seconds in the most.

Particularly good separation results are achieved if the separation fluid is electrically conductive, and the excess spray lacquer is ionized by the electrode device and is deposited on the separation surface, with the electrode device connected to the first pole of the high voltage source, and the separation surface with the second pole of the high voltage source.

The relationship between the biodegradable medium and the carrier fluid in the separation fluid may be individually adapted to the type of excess sputter, if the carrier fluid and the offset material are fed to the receiver independently of each other.

From an environmental point of view, it is especially beneficial if a separating liquid containing excess spray paints is regenerated and reused.

Regeneration can favorably occur through filtration, which includes one stage of filtering.

It is favorable if the viscosity measured on the separation surface of the separation liquid is measured. If necessary, the viscosity of the separation fluid can be adjusted by the addition of individual components.

With respect to a separation liquid, the above-mentioned problem is solved by the fact that the separation liquid has features of a separation liquid according to one of claims 1-17 of the claims.

Below, an exemplary embodiment of the invention is explained in more detail in the drawing. Shown:

FIG. 6: perspective view of the second structural example of the separation device for excess spraying containing several separation units and electrode devices according to FIG. 5;

FIG. 7: block diagram of the installation for supplying the separation fluid to the separation nodes.

In the beginning, reference is made to Figures 1 and 2. There is a reference marking 2 denoting a complete coloration of the surface treatment line in which the bodies of 4 cars are painted after they have been, for example, cleaned and de-skinned at the location of the pre-camera 2, not separately shown in the preceding position. processing

The coloring chamber 2 comprises a top-down colored tunnel 6, which is limited to the vertical side walls 8a, 8b and the horizontal ceiling 10 of the chamber, but from the ends and the bottom is open so that the air chamber with excess spraying can go down. The ceiling 10 of the camera is normally made as the lower limit of space (not shown) for supplying air with a filtering coating.

At the height flanked by the lower edges of the side walls 8a, 8b of the lower opening 12 of the painting tunnel 6, there is a steel structure 14, which is the support for the well-known trans-shipment system 16, which is not discussed here in more detail. With its help, the painting of the body of 4 cars can be transported from the entrance side of the painting tunnel 6 to its exit side. Inside the tunnel 6 of painting there are separately unplanned application devices, with which the 4-car body by itself is known to be applied varnish.

Under the lower slit 12 of the 6th dyeing tunnel, the separation space 18 upwards facing the tunnel 6 is dyed, in which the excessively sprayed lacquer, which is formed during the painting, is deposited.

The separation space 18 is limited to the visible in FIG. 2, a base plate 20, two vertical side walls 22a, 22b and two vertical end walls, in which two last ones in figures 1 and 2 are omitted (not shown). In the separation space 18 there is a separation device 24 with a plurality of located one after another in the direction of the separation space 18 separation units 26, which will still be discussed in more detail below.

In the separation space area 18, between the separating device 24 and the painting tunnel, there are two air guides 28a, 28b which, starting from the side walls 22a, 22b of the separation space 18, converge in the beginning to the bottom, and in their facing to

3

iA 106970 C2

the separation device 24 of the terminal region diverges to the lateral constraints of the separation device 24. Air guide guards 28a, 28b and the corresponding, not shown, air guides on the ends extend from the top to the separation device 24.

The separation knots 26 lie on the support frame 30 which allows air to flow down from the separation device 24. Under the separation device 24, there is another airborne control panel 32 extending along the separation device 24 in the space-space 18. The air-guide shield 32 has a vertical portion 32a that is directed to the left side the walls 22a of the separation space 18, in figures 1 and 2, and extending downwardly in the direction opposite the side wall 22b of the separation space 18 to the portion 32b. Including the vertical portion 32a of the airborne lining shield 32, and in the figures 1 and 2, the left side wall 22a of the separation space 18 is schematically shown only in FIG. 1, a prefabricated trench 34 extending parallel to the vertical portion 32 of the air guiding shield 32,

Figures 3 and 4 show two adjacent separation nodes 26 of the separation device 24. As can be seen, the separation unit 26 comprises two spaced, parallel, rectangular plates 36a, 36b, which are joined to each other by their opposite end faces with the help of a curved sites 38, whose outer contour in light in the cross section corresponds to a semicircle and forms the upper side of the separation unit 26.

At the highest point of the curved section of 38 separation knots 26, it is made in the form of a transverse groove 40, which will be further discussed in more detail.

The corresponding outer surfaces of the side plates 36a, 36b form the separation surfaces 42a or w42b, which will also be discussed in detail again once more.

At its lower edges, side plates 36a, 36b have one drainage groove 44a, 44b, which runs parallel to the side plates 36a, 36b of the separation knots 26 and in the direction of the first, nafig. 3 of the front, the end 46 of the separation unit 26 is inclined downwards. The effluent gutters 44a, 44b of the end end with side plates 36a, 36i of the separation unit 26 (cf. FIG. 3). The flush holes 44a, 44b at their end 48a or 48b on the first end 46 (cf. FIG 3) of the separation unit 26 are open.

As can be seen from Figures 1 and 2, each separation unit 26 comprises a first end wall 50a located at its first end 46. The opposite end of the separation units 26, which is not specifically provided with a reference symbol, is closed by a second end wall 50b. The solid walls 50a, 50b of the separation the nodes 26 close the ends of the corresponding overflowwell 40. Both ends 50a, 50b are made of plastic. The first end wall 50 of the separation unit 26 comprises two breakouts 52a, 52b, in which their ends 48a, 48b fall into one drainage groove 44a, 44b respectively. On the opposite drainage troughs 44a, 44b on the side of each end wall 50a, the drafts 54a, 54b are drained to the drafts 54a, 54b for drainage 52a, 52b. They are executed in the form of a profile, the cross section of which corresponds to the cross section of the seamsholes 44a, 44b.

If the separation device 24 is located in the separation space 18 of the dual chamber 2, then the trays 54a, 54b for draining each separation unit 26 act as an overhead groove 34.

In the separation device 24, two adjacent separation units 26 are located with respect to the distance between them. Between the two adjacent separation units 26, as well as the free side panels 36a or 36b of the two external separation units 26, within the separation device 24 extends respectively one electrode device 56, each of which is connected to a high voltage source, which in FIG. 4 is not shown separately. In one modification, electrode devices 56 can be fed from a single source of high voltage. Separation units 26 are grounded on the housing's potential.

Each electrode device 56 comprises two straight lines parallel to each other, electrode strips 58a, 58b. They hold on the field 60 of the electrode device 56 a grinding electrode 62 that passes between the electrode strips 58a, 58b, edges 64a, 64b which are arranged vertically to the last. In the crown region 66 of the electrode device, 56 electrode strips 58a, 58b contain several acting crowning electrodes of crown conductors 68. Crown conductors 68 pass in predetermined electrode strips 58a, 58b plane parallel to the edges 64a, 64b of the lattice electrode 62 and are arranged at identical distances from each other.

As is seen in Figures 3 and 4, the electrode devices 56 generally have a length that essentially corresponds to the length of the side plates 36a, 36b of the separation units 26. Electrode devices 56

4

iA 106970 C2

are arranged so that the lower edge 64b of the lattice electrode 62 is approximately at the height of the lower end of the side panels 36a or 36b.

In the operation of the separation device 24, on the respective separating surface 42a, 42b, the bifold 36a, 36b of the separation units 26, from top to bottom, in the waste troughs 44a, 44b flows a separation liquid, which is suitable for absorbing the particles of solid from the resulting process of painting the excess of the sprayed varnish.

To this end, the separation fluid is fed into the overflow groove 40 on the curved portion 38 of the separation units 26. From there, the separation fluid passing through the overflow hollow 40, the curved side faces 70a, 70b of the curved section 38 of the separation unit 26, respectively, in the form of a bound layer, reaches the side plates 36a, 36b and drains on their separation surfaces 42a, 42b and further as a boundary layer of separation fluid.

The number of crown conductors 68 of the electrode device 56 and their distance from each other may vary depending on the separation properties of the particles of the excess of the germination. In a given constructive example, four crown conductors 68 are provided, most of which is located near the curved portion 38 of the separation unit 26, and the lower crown conductor 68 is still in the region near the corresponding side plate 36a or 36b of the separation unit 26.

In FIG. 5 as the corresponding second constructive example, a modified separation unit 126 and a modified electrode device 156 are shown, and in the figure 6, a modified separation device 124 thereof. The details of the separation unit 126, the electrode device 156, and the separation device 124 corresponding to the parts of the separation unit 26, the electrode device 56, and the separation device 24 according to FIGS. 1-4, are indicated by the same reference symbols as the addition of 100.

The separation unit 126 differs from the separation unit 26, in particular by the fact that the troughs 144a, 144b protrude at the end 146 of the separation unit 126. The actuating pads 172a, 172b correspond to the above drainage ducts 54a, 54b, of which of these causes in the separation device 124 can be abandoned .

As can be seen in FIG. 6, projecting sections 172a, 172b of the waste troughs 144a, 144b of the separation unit 126 extend through respective openings 152a, 152b in each end wall 150a of the separating device 124.

In FIG. 5 shows a high voltage source 174 that is located between the side plates 136a, 136b of each separation unit 126 and is connected to the electrode device 156. Suitably, a high voltage source 174 may also be present at each separation unit 26 according to the first construction example. Accordingly, one separate separation unit 126 and a separate electrode device 156 form a separation module 176. Accordingly, each separate separation unit 26 and a separate electrode device 56 according to Figures 1 to 4 form a separation module 76.

In addition, in FIG. 5 shows the spacers 178a, 178b, 178c, which, below, in the middle and top, interconnect the inner surfaces of both side plates 136a, 136b of the separation unit 126.

In the electrode device 156 in accordance with the second construction example, vertically between the electrode strips 158a, 158b over the first crown conductor 168 passes a protective rail 180, thereby reducing the risk of contact with crown conductors 168 of the objects or particles incident from the tunnel 6 of the falling electrode device 16.

However, the above with respect to the separation unit 26, the electrode device 56 and the separation device 24, respectively, relates to the separation unit 126, the electrode device 156, and the separation device 124.

Further, the basic principle of the above-described devices is explained by the example of a separation device 24 according to figures 1-4. The use of the separation device 124 according to figures 5 and 6 in the painting chamber 2 is similar.

When coloring the bodies of cars in the tunnel 6 painting, the air in the chamber, which are located, is saturated with particles of excessively sprayed varnish. They may be even more liquid and / or sticky, but may also be more or less rigid. The air of the chamber containing an excessively sprayed lacquer through the lower cutout 12 of the dye tunnel 6 enters the partition space 18. There, the air is guided by air guides 28a, 28b in the direction of the separation device 24 and flows between the adjacent separating nozzles 26 in the direction of the lower air guide shield 32.

On crown conductors 68 in itself, known occurrences of crown discharges, whereby the particles of excess sputter in the air passing through the chamber, effectively ionized.

5

iA 106970 C2

The ionized particles of excess sputter undergo grounded on the housing potential of the circuit board 36a, 36b of two adjacent separation units 26 and a lattice electrod62 passing through the first portion 60 of the electrode device 56. In connection with the electric field ionized by the electrodes 62 and the side plates 32a, 32b, the electrons are arranged between the gratings particles of excess sintering are deposited on the separation surfaces 42a, 42b of the side plates 36a, 36b of the separation units 26 and are absorbed by the separating fluid flowing along them.

Part of the ionized particles of excess spraying is precipitated already in the second section of the 66 electrode device 56 in the region of the crown conductors 68 at the separation nodes 26. However, the current between the crown conductors 68 and the corresponding side plate 36a, 36b of the separation unit 26, the electric field is more heterogeneous than the electric field in the region of the lattice electrode 62 , because of which there is more directed and more effective separation of ionized particles of excess sputtering on the corresponding separation unit 26.

Purified by passing through the separation units 26, the lower airborne shield 32 is directed in the direction shown in Figures 1 and 2 to the right of the side wall 22b of the separation space 18, from where, if necessary, after a certain air conditioning, it can again be fed into the tunnel 6 of staining as fresh air. In the case of air conditioning, it can be, first of all, the adjustment oftemperature, humidity and, if necessary, the removal of solvents, which allappeals in the air.

Separating fluid discharging at the separation units 26, which now contains particles of excess sintering, falls below the waste gutters 44a, 44b of the separation units 26. Due to the troughs 44a, 44b, the saturated separation fluid flows towards the breakouts 52a, 52b in the corresponding end walls 50a, through them, and thence through the trays 54a, 54b to drain into the collector hole 34. Through the collector chute 34, a separation liquid containing particles of excess sintering flows from the dyeing chamber 2 and can be applied for purification and regeneration, in which the separation fluid vilnyayetsya particles from excess spray or removal.

In FIG. 7, reference no. 1082, in general, is indicated by the installation by which the separation fluid is directed to the separation units 26, and a separation liquid containing particles of a super-sprayed varnish is regenerated for reuse. Instead of separation nodes 26, separation nodes 126 may also be provided.

Installation 1082 is located in FIG. 7 to the left is the reservoir 1084, which mixes the main mixture of separation fluid, which contains all the components, except for the biodegradable environment. For this, the reservoir 1084 can be hydraulically connected to several barrels in which separate separation fluid components are supplied. In FIG. 7 as an example, dowitz barrels 1086a, 1086b are shown, which are connected to reservoir 1084 with the help of locking valves 1088a, 1088b of 1090a, 1090b.

In addition, the unit 1082 further comprises a second adhesive sealing tank 1092, which, on its side, is equipped with a shut-off valve 1094 of the conduit 1096 connected to the 1098 barrel in which the decoupling medium is supplied. The barrels 1086a, 1086b and 1098 can be placed on a loading platform 1100. From the reservoir 1084, the pipeline 1102 is connected to the assembly line 1104, which, on its side, is connected to the adhesive medium reservoir 1092 on the aid of the pipeline 1106. In pipelines 1102 and 1106, one pump 1108 or 1110 is installed, with the help of which the contents of the respective reservoir 1084 or 1092 can be injected into a pre-assembled pipeline 1104.

Prefabricated pipeline 1104 enters the receiver 1112, in which the main material arriving from the reservoir 1084 and the decolourising medium originating from the reservoir 1092 are combined and stirred.

From its side, the receiver 1112 is equipped with a pump 1114 of the pipeline 1116 coupled to a fine purification filter 1118, which itself is known. It passes through a separation fluid pumped by a pump 1114 from a receiver 1112, which is equipped with a pump 1120 for the discharge line 1122 again to leave it.

A downstream pipeline 1124 departing from the pump 1120, which has a first portion 1126a leading to the entry of a well-known viscometer 1128, as well as a section1126b, leading from the outlet of the viscometer 1128 to the assembly line 1104.

In the first section 1126a, bypass 1124 is installed a valve 1132 actuated by an electromagnet 1130 which is powered by a current from the energy source 1134, which also feeds the viscometer 1128. In addition, the energy source 1134 serves as a source of energy for the electromagnet 1136 controlled by it, valve 1138, which separates the assembly pipeline 1104 from the pipeline 1140, which brings up the fluid used-

carrier, or connects both pipelines 1140, 1104 with each other. The pipeline 1140 is connected to an unprescribed reservoir in which the carrier fluid is stored. Downstream from the point of connection to the bypass line 1124, proceeding from the fine purge filter 1118, the discharge line 1122 is connected to the supply line 1142, in which the spring-loaded valve 1144 is located. The supply line 1142 divides the sodium sleeves 1146a, 1146b, 1146c, which are installed according to One shut-off valve 1148a, 1148b, 1148s. Pipeline sleeves 1146a, 1146b, 1146c lead to the upper side of the separation unit 26.

The installation 1082 in aggregate comprises a number of supply pipelines 1142 with the respective arms 1146a, 1146b, 1146c, the number of which corresponds to the number of separation units 26 of the separator device 24.

From the overflow groove 40 of each separation unit 26 there is a selective pipeline 1150 which, on its side, has a shut-off valve 1152 to the return pipe 1154. The return pipe 1154 enters the upper space 1156 of the receiver 1112, which is separated from the downstream space 1158 by a non-woven filter 1160 . The nozzle filter 1160 is carried out above the separator liquid mirror located in receivers 1112 and is made in the form of a roller 1162 tape. The wound filter 1160 of nonwovens is taken in the collecting tank 1164. Between the spring valve 1144 and the pipe sleeves 1146a, 1146b, 1146c, the supply pipe 1142 is connected to another selective pipeline 1166 in which the shut-off valve 1168 is installed and which leads to the return pipe 1154. Drainage gutters 44a, 44b,

On the other side from falling into the supply line 1142, the discharge pipeline 1122 leads through the reverse portion 1172 to the lower space 1158 of the receiver 1112, with a spring-loaded shut-off valve 1174 on the reverse section 1172.

The installation 1082 described above functions as follows:

The component in the desired proportion, located in tanks 1084 or 1092, the assembling pipeline 1104 is transported to the lower space 1158 of receiver 1112. The available separator fluid, along with the freshly mixed portion, also contains a purified separation fluid, which will be further discussed again.

The separation fluid, located in the lower space 1158 of the receiver 1112, passes through a fine purification filter 1118 and is directed to the corresponding separation unit 26 along the supply line 1142 with the sleeves 1146a, 1146b, and 1146c.

With the help of the pump 1120 downstream of the fine purification filter 1118, the separation fluid is fed to the performance at which the spring-loaded valve 1144 opens in the conveying conduit 1142, for example, 20 liters per minute.

Due to the separation of the supply pipe 1142 on the sleeves 1146a, 1146b, 1146c, it may be possible to fine-tune the amount of separation fluid entering the corresponding unloading device 26. For this, the valves 1148a, 1148b, 1148c are respectively included in such a way that the separation fluid is delivered to the unloading device 26, either one, or two, or on all three pipelines 1146a, 1146b, 1146c. If necessary, there may bemoremore three pipeline sleeves 1146 with valves 1148. For example, the separation fluid leaves piping sleeves 1146a, 1146b, 1146s with a flow of 0,2 to 0,3 liters per minute. The consumption of the pipeline sleeve 1146a, 1146b, 1146c may have been regulated through their passage cross section, or using valves 1148a, 1148b, 1148c, the passage cross-section of which is regulated.

If the performance of the pump 1120 in relation to the shut-off action of the spring valve 1144 in the supply line 1142 is too large, then a spring-loaded shut-off valve 1174 is opened in the return pipe 1172 and the separation fluid is fed from the fine purification filter 1118 in the circulating circuit back to the receiver's lower space 1158. 1112. For example, the shut-off valve 1174 opens if the pressure on it exceeds 1 bar.

With viscometer 1128, the viscosity of the separation fluid can be measured, which proceeds from the fine purification filter 1118. For this purpose, a magnetic valve 1132 opens, so that a portion of the separation liquid coming from the filter 1118 fine purification of the separation liquid enters the viscosimeter 1128. The residual viscometer 1128 separates the fluid through the pipe line 1126b again into the collecting pipeline 1104 and then again into the lower space 1158 of the receiver 1112. If the measurement in Viscosity indicates that the separation fluid has an extremely high viscosity, the magnetic valve 1138 may be open so that the corresponding carrier fluid from

the pipeline 1140 enters the prefabricated pipeline 1104, whereby the separation fluid receiver 1112 is diluted and its viscosity decreases.

If the viscosity of the separation fluid is too small, it can be increased by appropriate changes in the supply of components from the barrels in which they are supplied.

The separating unit 26 of separating liquid containing particles of an overly sprayed lacquer proceeding from the waste troughs 44a, 44b, 144a, 144b through the selective pipelines 1170 and the return pipe 1154 is directed to the upper space 1156 of the receiver 1112. There, under the force of weight, it passes through the filter 1160 a non-woven material down to the lower space 1158 of the receiver 1112, in which it enters a filtered and substantially free part of the super-sprayed varnish. In this case, the particles of the excessively sprayed varnish contained in the separation fluid remain on the filter 1160 of nonwovens. If the current in the receiver 1112 section of the filter 1160 from non-woven material absorbed the maximum number of particles of excess sprayed varnish,

In the event that the filtering effect of the non-woven fabric filter 1160 subsequently deteriorates or is in principle not sufficient to delay the addition of small particles, they are filtered using a fine purification filter 1118, so that only a substantially purified and unsaturated separation occurs in the discharge pipeline 1122 liquid, the azette is sent to the separation units 26.

By selective pipelines 1150 and 1170, pipelines 1142 may be discharged by the conduits 1146a, 1146b, 1146c and the overflow groove 40, 140 of the respective separation unit 26. This may be necessary, for example, if a separation fluid is to be replaced.

Due to the installation of 1082, the separation fluid can be used in a circulating circuit in which there is a separation device 24 with separation units 26. It is possible to release a separating liquid containing particles of an excessively sprayed lacquer, from which they are again supplied to the circulating circuit.
