Description

Technical Field

[0001] The present invention relates to the technical field of dust removal for cat litter particle production lines, and particularly to an industrial production line for deodorant cat litter particles with efficient dust removal. Background Art

[0002] Cat litter is a granular object used by pet owners for their cats to bury feces and urine. It is in the shape of long strips and has good water absorption. Inevitably, small particle impurities and fine dust adhering to the cat litter particles will be mixed into the cat litter during the production process. To improve the quality of cat litter and reduce the harm of cat litter dust to the respiratory tract of pet cats, it is generally necessary to perform a dust removal operation on the cat litter before bagging to reduce the small particle impurities in the cat litter and improve the safety of use.

[0003] In the prior art, the dust removal operation on the cat litter production line is generally carried out using a dust removal box. The dust removal box generally includes a box body and a conveying component arranged in the box body, such as a conveyor belt. During operation, the cat litter is put on the conveyor belt and moves in the box body along with the conveyor belt. A suction pipe is fixedly connected to the box body, and an exhaust fan connected to the suction pipe is also arranged outside the box body. Through the exhaust fan, the small particles in the cat litter during the conveying process can be sucked out and then sent to the dust treatment system. However, in the actual operation process, such a method can only remove some larger particles and impurities in the cat litter, and it is difficult to remove the fine dust adhering to the surface of the cat litter particles well. And such fine dust is one of the important inducements for pet cats to inhale and cause respiratory diseases. Therefore, efficiently removing the fine dust adhering to the cat litter particles on the production line is an important task to ensure the safety of cat litter use. Summary of the Invention

The connection point of the movable connecting rod 301 and the biasing turntable 302 is located on the outer ring of the biasing turntable 302. A motor 3 is fixedly connected to the back of the biasing turntable 302. There is a communication port on the back of the outer box 1, and a motor bracket 102 is fixedly connected through the communication port. The motor 3 is placed inside the motor bracket 102. When the motor 3 starts, it drives the biasing turntable 302 to rotate, and through the movable connecting rod 301, it pushes the sieve moving block 203 and the dust removal sieve bucket 2 to move left and right. The sieve bucket slide rod 201 can slide left and right along the sieve bucket slide rail 101. The dust removal sieve bucket 2 is in the shape of a dustpan, and the width of the dust removal sieve bucket 2 is smaller than the inner wall spacing of the outer box 1.

Uniform dust falling openings 202 are provided at the bottom of the dust removal sieve bucket 2, so that the cat litter put into the dust removal sieve bucket 2 can have the broken cat litter and dust at the bottom fall out from the dust falling openings 202 during the sieving process, thereby ensuring that the broken dust in the cat litter after sieving from the dust removal sieve bucket 2 is reduced, and thus realizing the preliminary sieving and separation of the separated broken cat litter and broken dust in the cat litter, and improving the efficiency of subsequent dust removal work.

[0019] Please refer to Figure 3-4, roller openings are respectively provided at the bottom of both sides of the front half of the outer box 1, and a roller group 4 is movably connected through the roller openings, the roller group 4 is composed of three rollers, and the positions of the three groups of rollers are consistent with the vertices of the right triangle, the two ends of the rollers extend to the outside of the outer box 1, and are fixedly connected to the outside with roller gears 401, and the middle of the roller group 4 is movably connected with a mesh conveyor belt 402, the mesh conveyor belt 402 is in a grid shape, and the top of the longitudinal grid is fixedly connected with a vertical guide rail 403, so that the height of the longitudinal line of the mesh conveyor belt 402 is higher than the transverse line, and cat litter particles 8 are movably placed on the mesh conveyor belt 402, and the roller gear 401 is driven to rotate by an external power device, driving the roller group 4 to rotate counterclockwise, thereby transmitting the cat litter particles 8 on the upper side thereof The cat litter particles 8 are sent to a low place, and the spacing between the vertical guide rails 403 is consistent with the diameter of the cat litter particles 8, so that the cat litter particles 8 can fall vertically into the middle of two groups of adjacent vertical guide rails 403. Roller brush openings are respectively opened on the tops of both sides of the front half of the outer box 1, and a roller brush group 5 is movably connected through the roller brush openings. The roller brush group 5 includes a first roller brush 501, a second roller brush 502 and a third roller brush 503. The first roller brush 501, the second roller brush 502 and the third roller brush 503 are arranged in sequence from top to bottom, and the peripheries of the first roller brush 501, the second roller brush 502 and the third roller brush 503 are fixedly connected with bristles 504. The roller brush group 5 is located in a plane parallel to the inclined top surface of the mesh conveyor belt 402, and its inclination angle is consistent with the angle of the top surface of the mesh conveyor belt 402, thereby ensuring that the roller brush group 5 is The ends of the bristles 504 on the periphery of each group of roller brushes can contact the mesh conveyor belt 402, the first roller brush 501 is installed obliquely with the left side higher and the right side lower, and the left side of the bristles 504 on the periphery of the first roller brush 501 is in close contact with the left inner wall of the outer box 1, and a gap is provided between the right side and the right inner wall of the outer box 1, the second roller brush 502 is installed obliquely with the left side lower and the right side higher, and the left side of the bristles 504 on the periphery of the second roller brush 502 is in close contact with the left inner wall of the outer box 1, and the right side is in close contact with the right inner wall of the outer box 1, the third roller brush 503 is installed horizontally, and both sides of the bristles 504 on the periphery of the third roller brush 503 are in close contact with the inner walls of both sides of the outer box 1, and a power gear 505 is fixedly connected to the end of the roller brush group 5, and the power gear 505 is driven to rotate by an external power device, driving the roller brush group 5 to rotate. Rotate counterclockwise. When the cat litter particles 8 in the outer box 1 pass through the vibrating screen and fall onto the mesh conveyor belt 402, they are first moved by the first roller brush 501 to be placed longitudinally along the gaps in the vertical guide rails 403. The cat litter particles 8 that are successfully placed longitudinally move down from the bottom of the first roller brush 501 along the mesh conveyor belt 402. At the same time, the bristles 504 on the first roller brush 501 clean and remove the dust adhering to the surface. The excess cat litter particles 8 that have not been successfully arranged longitudinally slide along the lower part of the first roller brush 501 where there are no bristles 504 to the second roller brush 502. After a second movement by the second roller brush 502, they are placed longitudinally along the gaps in the vertical guide rails 403, thereby ensuring that all the cat litter particles 8 on the mesh conveyor belt 402 are finally embedded in the gaps in the vertical guide rails 403 for longitudinal arrangement.Driven by the roller set 4, it rotates to the third roller brush 503, and the bristles 504 on the third roller brush 503 perform the last cleaning of the adhered floating dust, thereby reducing to a greater extent the dust carried on the produced cat litter particles 8. The inclined installation of the first roller brush 501 and the second roller brush 502 causes them to push the cat litter particles 8 to rotate along the central axis of the cat litter particles 8 between the vertical guide rails 403 during their own rolling process, realizing a comprehensive cleaning of the dust on the surface of the cat litter particles 8. A finished product collection hopper 7 is movably placed on the front of the outer box 1. After the dust removal, the cat litter particles 8 fall into the finished product collection hopper 7 for collection and subsequent packing work, greatly reducing the dust content in the finished cat litter.

[0020] Please refer to Figure 5 , a funnel-shaped air guide cover 6 is fixedly installed in the middle of the outer box 1. The funnel-shaped air guide cover 6 is located inside the mesh conveyor belt 402. Its top is closely attached to the bottom of the inclined top surface of the mesh conveyor belt 402 and covers the entire inclined top surface range. The end of the funnel-shaped air guide cover 6 is fixedly connected to a fan 601. The fan 601 is fixed to the side of the outer box 1, and the connection at the end of the funnel-shaped air guide cover 6 leads to the outside of the outer box 1. A dust collection bag is fixedly installed outside the fan 601. When the fan 601 is started, it adsorbs the inside of the funnel-shaped air guide cover 6, thereby ensuring that the cat litter particles 8 are closely attached to the upper surface of the mesh conveyor belt 402 while adsorbing and collecting the dust swept by the bristles 504, thus achieving an efficient dust removal effect.

[0021] The working principle of the usage method of the present invention is as follows: During use, the cat litter particles 8 produced on the production line are put into the dust removal screen 2, and the motor 3 drives the dust removal screen 2 to shake left and right along the screen slide rail 101, so that most of the scattered dust particles in the cat litter fall and are discharged from the dust outlet 202. A cleaning port is provided on the back of the outer box 1 to regularly clean the sieved dust particles. The cat litter particles 8 after preliminary dust screening are scattered along the mouth of the dust removal screen 2 onto the mesh conveyor belt 402. In the process of following the mesh conveyor belt 402 to move downward, they are first moved by the first roller brush 501 to be placed longitudinally along the gap of the vertical guide rail 403. The cat litter particles 8 that are successfully placed longitudinally move downward from the bottom of the first roller brush 501 along the mesh conveyor belt 402 under the adsorption of the fan 601. At the same time, the bristles 504 on the first roller brush 501 clean and remove the dust adhered to its surface. The dust adhered to the surface of the cat litter particles 8 is sucked into the funnel-shaped air guide cover 6 and then discharged to the outside of the outer box 1 for collection. The excess cat litter particles 8 that have not been successfully arranged longitudinally slide along the lower part of the first roller brush 501 where there is no bristle 504 to the second roller brush 502. After a second flick at the second roller brush 502, it is placed longitudinally along the gap between the vertical guide rails 403, thereby ensuring that all the cat litter particles 8 on the mesh conveyor belt 402 are eventually embedded in the gap between the vertical guide rails 403 for longitudinal arrangement, and are driven by the roller group 4 to rotate to the third roller brush 503, where the bristles 504 on the third roller brush 503 are used to sweep away the adhered floating dust for the last time, thereby reducing the dust carried on the produced cat litter particles 8 to a greater extent. After the dust removal is completed, the cat litter particles 8 fall into the finished product collection bucket 7 for collection and subsequent packaging, which greatly reduces the amount of dust contained in the finished cat litter.
