Vibrating Screening Machine

Vibratory Screening Machine

This creation generally relates to methods and devices for sieving materials, especially for separating materials of different sizes.

The linear vibrating screen uses the vibration motor as the source of vibration, so that the material is thrown up on the screen while moving forward in a straight line. The material enters the feed inlet of the screening machine evenly from the feeder, and produces several specifications through the multi-layer screen. The oversize and undersize are discharged from their respective outlets. It has the functions of low energy consumption, high output and simple structure.

The conventional vibrating screening machine has the following disadvantages:

1. The conventional system has a hose located on the upper layer of the vibrating machine, which takes up space.

2. The conventional screen will be tensioned from the side, leaving a crown perpendicular to the flow of the material to be screened, thus causing troughs and low efficiency in the flow.

3. Large-volume particles of materials to be screened will stay in the opening.

4. If you want to increase the screening capacity of separated materials, you need to increase the size of the machine.

For this reason, how to solve the above-mentioned problems is the subject that the industry-related industries urgently want to study.

FIG. 6 shows a partial side perspective view of the screen plates 410 and 420, the cleaning tray 440, the side groove 430, and a part of the tensioning device 450. As shown in FIG. As shown in FIG. 6, the flexible material 405 covers the outlet pipe 133 of the feeding assembly 130. The flexible material 405 is configured to control the flow of the material from the outlet pipe 133 to the screen assembly 400 so that the material flow is evenly distributed on the screen assembly 400, thereby maximizing the efficiency of the vibrating screening machine 100. As shown in Figure 6, the first screen 410 and the second screen 420 do not include the screens 409 and 419, but it should be understood that when the vibrating screening machine 100 is used to separate materials of different sizes, the first and second screens The second screen plates 410 and 420 are covered by the screens 409 and 419 and can be replaced as described herein when the screens are worn or damaged. 6, the first screen plate 410 includes a rib 412, a beam 414, an upper end plate 416 and a lower end plate 418. The second screen plate 420 includes a rib 422, a beam 424, an upper end plate 426, and a lower end plate 428. The opposite ends of the ribs 412 and 422 are from the midpoint between the upper end plate 416 and the lower end plate 418 of the first sieve plate 410 and the midpoint of the upper end plate 426 and the lower end plate 428 of the second sieve plate respectively in the side grooves 430 and Extend between 430'. The plurality of beams 414 and 424 extend from the upper end plates 416 and 426 to the lower end plates 418 and 428, respectively. The midpoint 415 of each stringer 414 and the midpoint 425 of each stringer 424 cross the top surfaces of the ribs 412 and 422. The midpoints 415 and 425 are raised relative to the opposite ends of the beams 414 and 424 so that the beams 414 and 424 form a "crown" or bend on the first and second screen plates 410 and 420. Although the first screen 410 and the second screen 420 are shown as having a single rib 412 and 422, respectively, it is understood that the first screen 410 and the second screen 420 may include other configurations. The first screen 410 and the second screen 420 may include a plurality of first ribs and a plurality of second ribs, respectively, as long as the additional ribs provide the functions as described herein. In some embodiments, at least one (or in some embodiments, each) of the plurality of first ribs and the plurality of second ribs may be assembled in the model of rib 412 or rib 422.

Unlike the screening elements of other systems, such as those disclosed in US Patent No. 6,431,366, the stringers 414 and 424 can be replaceable units and can be bolted rather than welded to the ribs 412 and 422. This structure eliminates the closely spaced welded joints between the ribs 412 and 422 and the stringers 414 and 424, which are commonly found in welded screen panels. This arrangement eliminates the shrinkage, thermal deformation, and drop associated with closely spaced welded joints, and enables fast replacement of worn or damaged stringers 414 and 424 in the field. The replaceable stringers 414 and 424 may include plastic, metal, and/or composite materials, and may be constructed by casting and/or injection molding processes. Although not shown in FIG. 6, the screens 410 and 420 are configured to support screens 409 and 419, and the screens 409 and 419 extend across the surfaces of the first screen 410 and the second screen 420, respectively, covering the ribs 412 and 422 and stringers 414 and 424 are shown in FIG. 5.

Further referring to FIG. 6, the upper end plate 416 of the first screen plate 410 is raised relative to the lower end plate 418. Similarly, the upper end plate 426 of the second screen plate 420 is raised relative to the lower end plate 428. The cleaning tray 440 extends between the lower end plate 418 of the first screen plate 410 and the upper end plate 426 of the second screen plate 420. The first screen 410, the cleaning tray 440, and the second screen 420 are configured such that the material flow from the outlet pipe 133 and the flexible material 405 of the feed assembly 130 traverses the first screen 410 and the second screen 420 before crossing the second screen 420. The tray 440 is cleaned. This configuration makes it possible to effectively separate the material flow by increasing the surface area used by the screening material to flow to the large and fine material collection assembly 170 and the small and fine material collection assembly 160 without increasing the footprint of the vibrating screening machine 100.

FIG. 7 shows an isometric side view of the cleaning tray 440 docked with the first sieve plate 410 and the second sieve plate 420. As shown in FIG. 7, the cleaning tray 440 includes an upper member 442 having a top portion 442A and a bottom portion 442B, a lower member 444 having a first end portion 444A and a second end portion 444B, and a first end portion 446A and a second end portion 446B.offlexion side members 446. The curved side member 446 includes an "S"-shaped curve called "Ogee", which is discussed in more detail below. The top 442A of the upper member 442 is connected to the lower end plate 418 of the first screen plate 410. The bottom 442B of the upper member 442 is connected to the first end 444A of the lower member 444.

The second end 446B of the curved side member 446 is bent on the upper end plate 426 of the second screen plate 420.

The final configuration of the cleaning tray 440 creates a weir 447, which is a trough or depression that provides a structure for collecting the liquid or slurry stream 500 to be screened. The embodiment of the cleaning tray 440 with the "S"-shaped weir structure has functional significance in the field of fluid dynamics. The "S"-shaped weir structure is usually described as a slight rise from the bottom of the weir and rises to the maximum rise point 449 at the top of the "S"-shaped curve of the "Ogee" structure.

FIG. 14 is a side view of the screen assembly 400 similar to FIG. 7, showing details of the tensioning element 450 tensioning the second screen 419 along the second screen 420. As shown in FIG. 14, the material 500 to be screened flows through the first screen assembly 409 to the discharge end 409B of the first screen assembly 409 via vibration. During the passage, material particles 500 of appropriate size pass through the openings or holes 488A of the first screen assembly 409. After passing through the discharge end 409B of the first screen assembly 409, the material 500 enters the cleaning tray 440 and crosses the curved side member 446 and the maximum ascent point 449. After passing the maximum ascent point 449, the material 500 falls on the impact area 448 of the second tray 419, and then vibrates on the second screen 419, passing from the input end 419A to the discharge end 419B, where the material particles 500 of appropriate size follow Pass through the second screen 419.

As can be understood from FIG. 14, and as explained in further detail below, the discharge ends 409B, 419B of the screen assemblies 409, 419 are attached to the fixed plate clamp 455B, and the opposite input ends 409A, 419A are attached to the tension The tension band 455 of the device 450. When the tension belt 455 is rotated, the screens 409 and 419 are tensioned back and forth across the corresponding first and second screen plates 410 and 420, and the tensioning direction is the same as the direction in which the material to be screened flows through the screen plate assembly 400. This is an improvement over the early system. The screen components of the early system were tensioned from the side, leaving a crown perpendicular to the flow of material to be screened, which caused troughs and low efficiency in the flow.

In Figure 15, parts of the screens 409, 419 have been cut away to show the various aspects of the screen plates 410, 420 below the screens. It is shown that the material 500 crosses the cleaning tray 440 and hits the impact area 448 of the second filter 419.

16A and 16B show multiple views of the screen assembly 419 used in the vibratory screening machine 100 and the screen plate assembly 400 described above. Although the following description of the embodiment depicted in FIGS. 16A and 16B refers to the second screen assembly 419, it should be noted that this discussion is equally applicable to the first screen assembly 409; the first screen assembly 409 can generally be used with the screen The components 419 are equivalent, but can optionally have different sizes and configurations, such as different size impact areas 448 (smaller or larger), different size opening configurations, combinations thereof, and the like.

Figure 16A is a front perspective view of a screen 419 according to one or more embodiments of the present creation. The screen 419 is configured to be removably secured to the second screen plate 420 under tension in the manner described herein. The screen 419 includes an input end 419A and an opposite discharge end 419B. The screen 419 has a transverse dimension between the ends 419A and 419B and a longitudinal dimension between the opposite side edges 483. The filtration area 488 is defined by a plurality of individual openings or holes 488A extending substantially across the surface of the screen 419. The opening 488A has a selected size, for example, a size determined by a side length having a corresponding value in the range of about 20 microns to about 100 microns. In some embodiments, the opening 488A may be rectangular in shape, and may have a substantially uniform width or substantially uniform thickness in the range of about 43 microns to about 100 microns and in the range of about 43 microns to about 2000 microns. The basically uniform length.

In the embodiment shown in FIG. 16A, the filter area 488 is framed by an impact area 448 formed along the input end 419A, a strip 486 formed along the discharge end 419B, and an opposite side strip 484 along the corresponding side edge 483. live. The ends of the impact area 448, the straps 486, and the side straps 484 are integrally joined together at abutting points, and together provide structural support for the filter area 488 to prevent tearing and the like during placement and use of the machine 100. Referring to FIG. 14, as the material 500 flows through the curved member 446 of the cleaning tray 440, the material 500 falls to the impact area 448. The impact area 448 protects the integrity of each opening 488A and prevents or reduces the possibility of large particles trapping in the opening 488A. As shown in FIG. 14, as the material 500 flows from the input input end 419A to the discharge end 419B, particles of the appropriate size of the material 500 pass through the opening 488A. The impact area 448 may have different sizes and configurations depending on the screening application and desired flow characteristics.

As shown in FIGS. 16A and 16B, a first binding tape 481A is provided along the input end 419A, and a second binding tape 481B is provided along the discharge end 419B. Each binding belt 481A, 481B may be a substantially "U"-shaped metal belt, which is integrated with the input end 419A and the discharge end 419B substantially along the length of each end 419A, 419B, respectively. Although other devices may be used to attach the binding tapes 481A, 481B to the screen 419, the binding tapes 481A, 481B are configured to withstand considerable force during the operation of the vibrating screening machine 100 without being separated from the screen 419 or allowing The screen 419 is loosened from the screen plate 420.

Fig. 16B is a side view of a filter 419 used in an exemplary embodiment of the present creation. When viewed from the side shown in FIG. 16B, the screen 419 has a thin profile. As shown in FIG. 16B, the sieve filter 419 includes a material input surface 485A located on the upper side and a material output surface 485B located on the opposite lower side thereof. A separate screen opening 488A extends from the input surface 485A to the output side 485B so that during vibratory screening, a single particle passes through the filter area 488. In the embodiment depicted in FIG. 16B, the first and second binding tapes 481A, 481B hang downward from the underside of the screen 419. Each binding tape 481A, 481B is bent toward the center of the screen 419, for example, in an "L" shape or a "C" shape.

The size of the screen components 409, 419 is set to match the size of the plates 410, 420. In some embodiments, the screen assemblies 409, 419 preferably have a length of about 56 cm, a width of about 30 cm, and a thickness of about 0.25 cm. The impact area 448 is about 3 cm wide; a narrower or wider impact area 448 can be used, the former reduces the protection of the opening 488A, and the latter reduces the number of the opening 488A. The strip 486 and the side strips 484 are approximately 1 cm wide. The screens 409, 419 are preferably made of polyurethane. Although an exemplary embodiment of the screen 419 used in the vibratory screening machine 100 described herein is shown in FIGS. 16A and 16B, it is understood that the machine 100 can be configured to interact with screens, screen materials, and screens. The optional structure of the net feature (opening/hole size, connection mechanism, etc.) is used together. It can be found in the applicant's U.S. Patent 9,409,209, U.S. Patent Application Publication 2013/313,168A1, U.S. Patent Application Publication 2014/0262978A1 and U.S. Patent Application Publication 2014/0262978A1, and U.S. Patent Application Publication 2016/0310994A1. 409 and 419 are examples of screens, screen materials, and screen features used with the machine 100, the disclosures of which are fully incorporated herein by reference.

The method for attaching the screen assemblies 409, 419 to the screen plates 410, 420 will now be described. As shown in FIG. 14, the plate clamp 455B is adjacently fixed to the corresponding output ends 410B, 420B of the plates 410 and 420. The size and configuration of the plate clamp 455B are designed to attach the discharge ends 409B, 419B of the screens 409, 419 to the screen plates 410, 420. In one embodiment, the plate clamp 455B extends substantially along the length of the output ends 410B, 420B, which is similar to the binding tape 481A, 481B extending along the length of the screen assembly 409, 419. In Figure 14, the plate clamp has an "L" shape when viewed from the side profile, although other joining configurations may also be used, such as a curved "C" shape. As can be understood from FIG. 14, the second binding tape 481B along the discharge ends 409B, 419B of the screen assemblies 409, 419 is joined to the plate clamp 455B so that the "L" or "C" shape of the binding tape 481B The "L" shape or "C" shape of the board clip 455B intersects each other. Tension is applied to unfold the screen assemblies 409, 419 to cover the screen plates 410, 420 toward the input ends 410A, 420A so that the binding clip 481B remains interconnected with the plate clip 455B. As the screen assemblies 409, 419 are unfolded on the screen plates 410, 420, the first binding belt 481A of the screen assemblies 409, 419 is then joined to the tension belt 455 of the tensioning device 450, so that the tension of the tension belt 455 The L" or "C" shape is interconnected with the first binding tape 481A. Then tension is applied to the screen assemblies 409, 419 through the tensioning device 450, thereby selectively locking the first binding belt 481A to the tensioning belt 455, so that the screening programs 409, 419 follow the screen plates 410, 420 The strainer is tight, and is used to screen the material 500 particles during the operation of the machine 100.

After a period of use, the screens 409, 419 can be selectively removed from the plates 410, 420 to replace the screens 409, 419 with new ones. In the method of removing the screen, the tensioning device 450 is used to release the tensioning strap 455 from the first strap 481A. The screen assemblies 409, 419 are then pulled or slid toward the discharge ends 410A, 420A of the plates 410, 420 to release the second binding tape 481B from the plate clamp 455B.
