Centrifugal fluid cleaner

Application filed March 19, 1926. Serial No. 95,988.

My invention relates to improvements in centrifugal fluid cleaners, and is more particularly adapted to that class of cleaner utilized for cleaning gas or air, such as re5 moving particles of foreign matter from gas or air.

The object of my invention is to provide a separator of the class described, wherein the incoming gas or air is given a circular 10 motion, so that the heavier particles will be thrown outward by centrifugal force through a novel arrangement of separating vanes into a compartment where the centrifugal motion is stopped and all other motion of the sepa15 rated particles halted, thereby allowing them to settle into a receiver from which they may be removed as necessary.

A further object of my invention is to so construct a device of this character that the 20 parts of the device subject to the most wear may be removed and replaced without disturbing or replacing other sections of the device.

Another advantage of my invention is that 25 the device may be constructed in any size, from very small to very large, without any change in the principle of operation or general design.

These and other features will be fully ap30 parent as the description proceeds, in which the novel combination of parts will be hereinafter described in connection with accompanying drawings.

Figure 1 is a side elevation, partly in sec35 tion, showing my improved separator.

Figure 2 is a sectional view taken on line 2—2 of Figure 1.

Figure 3 is an enlarged detailed view illustrating the structure of the separating vanes. 40 Referring to the accompanying drawings, in detail, wherein like reference characters denote corresponding parts throughout the several views, the Figure 1 designates a cylindrical drum, which may have a cone-shaped 45 bottom 2, while its upper end has connected thereto a cover 4. The central portion of the cover 4 has passing downwardly therethrough a pipe 6. Upon, referring to the drawing, Figure 2, it will be noted that pipe 50 6 is concentrically arranged within drum 1.

As best shown in Figure 1 of the drawings, the cone bottom 2 forms a settling chamber for the dust,, or other foreign substance, and the discharge mouth of the same is nor55 mally closed by any type of valve, the valve shown being that of the counterweighted conical type, as indicated at X, the same being pivotally connected in any suitable manner to the cone shell.

The lower end of the pipe 6 has connected eo thereto a cone shaped bottom 7, the apex of which has connected thereto a downwardly projecting pipe 8, the purpose of which will be hereinafter more fully described.

Connected to the lower end of pipe 6, upon 65 its outer face, is a downwardly inclined bottom 9, the outer edge of which is provided with a flange 10 to which are connected in any suitable'manner the lower end of the deflecting vanes 11 having inturned lips 18, the 70 upper ends of which vanes are connected to an annular ring 12, which ring is connected to the under face of the cover 4.

The outer drum 1 is provided with a suitable elongated opening which has in connec- 75 tion therewith an inlet pipe 13. The vanes 11, are secured at intervals so as to have a narrow space between vanes, commencing at a point 14 on drum 1 where pipe 13 enters drum 1. This plurality of vanes 11, extend- 80 ing around pipe 6, form a passageway for the gas or air as shown in Figure 2. The passageway from pipe 13 is formed by a plate 16, one end of which is connected to the inner face of drum 1, adjacent th the con- 85 nection of pipe 13, as indicated at 50, while its other end is connected to pipe 6 at 51. As the circular passageway ends at plate 16 the pipe 6 is provided with an elongated opening 17 through which the cleaned air or gas 90 passes into pipe 6 and is conveyed upwardly therethrough.

Secured at spaced intervals within the drum 1 and between its inner surface and the outer surface of the wall formed by the series 95 of adjacent vanes 11 is a plurality of radially extending baffles 15, which form a plurality of pockets or compartments in the space between vanes 11 and the inside of drum 1. These baffles 15 are connected in any suitable 100 manner to the top 4 and drum 1 and extend the entire length of vanes 11. The compartments or pockets thus formed are open at their lower end.
