Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste screening technology, specifically a sorting device for industrial solid waste screening. Background Technology
[0002] With the rapid development of industry, the amount of industrial solid waste generated is increasing day by day. Industrial solid waste refers to various waste residues, slags and other wastes generated during industrial production processes. Crushing these solid wastes and then effectively screening and sorting them is a key link in realizing resource recycling and environmental protection.
[0003] Traditional industrial solid waste screening and sorting devices generally have some shortcomings. In the feeding stage, there is a lack of effective material dispersing structure. Industrial solid waste comes from a wide range of sources and has a complex composition. During the crushing and rolling process, lumps or agglomerates often occur. Directly feeding such materials into the screening device can easily cause screen blockage, which seriously affects the screening efficiency. Moreover, the uneven distribution of materials on the screen causes some screen areas to be overloaded, which greatly reduces the screening accuracy. A large number of qualified particles that should be screened out cannot pass through the screen in time, resulting in resource waste and increased subsequent processing costs. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a sorting device for industrial solid waste screening, which solves the problem of solid waste agglomerating or clumping during the screening process, severely affecting screening efficiency.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A sorting device for industrial solid waste screening includes: a screening box, with a screen plate slidably connected to the inner wall of the screening box, and a collection frame slidably connected to the inner wall of the bottom of the screening box; and a feeding structure, with the outer wall of the bottom of the feeding structure fixedly connected to the outer wall of the top of the screening box; the feeding structure includes a feeding pipe, a rotating rod rotatably connected to the inner wall of the side of the feeding pipe, a worm gear fixedly connected to the outer wall of the rotating rod, a motor rotatably connected to the outer wall of the rotating rod away from the worm gear, a connecting rod rotatably connected to the inner wall of the top of the feeding pipe, a worm wheel fixedly connected to the outer wall of the top of the connecting rod, a turntable fixedly connected to the outer wall of the bottom of the connecting rod, a striking plate fixedly connected to the outer wall of the turntable, and a feed guide plate fixedly connected to the outer wall of the feeding pipe.
[0009] Preferably, the outer wall of the motor is fixedly connected to the outer wall of the feeding pipe, the outer wall of the worm gear meshes with the outer wall of the worm wheel, and the striking plates are arranged in a ring around the central point of the turntable. The motor drives the rotating rod to rotate, and the worm gear on the rotating rod rotates accordingly. Since the worm gear meshes with the worm wheel, the rotation of the worm gear drives the worm wheel to rotate, which in turn drives the connecting rod to rotate. The turntable fixedly connected to the bottom of the connecting rod also rotates together.
[0010] Preferably, the outer wall of the top of the screening box has a feed inlet, the outer wall of the side of the screening box is symmetrically and fixedly connected with a slide rod, the outer wall of the slide rod is fixedly connected with a baffle, the outer wall of the baffle is fixedly connected with a pressure spring, the inner wall of the screening box is rotatably connected with an opening and closing plate, the outer wall of the screening box away from the slide rod is fixedly connected with a support plate, the outer wall of the bottom of the support plate is fixedly connected with a motor, the outer wall of the motor is fixedly connected with a cam, and the inner wall of the screening box is symmetrically and fixedly connected with guide plates.
[0011] Preferably, the outer wall of the slide rod is slidably connected to the inner wall of the screen plate, the outer wall of the pressure spring on the side away from the baffle is fixedly connected to the outer wall of the screen plate, the cam is fixedly connected to the rotating shaft on the motor, and the outer wall of the cam is slidably connected to the outer wall of the screen plate. When the motor starts, its rotating shaft drives the cam to rotate. During the rotation, the outer wall of the cam continuously contacts and pushes the screen plate, causing the screen plate to slide on the slide rod. At the same time, because the screen plate is close to the baffle, the pressure spring is compressed. When the cam rotates to a certain position and no longer exerts a pushing force on the screen plate, the elastic force of the pressure spring causes the screen plate to return to its original position, and this process is repeated.
[0012] Preferably, the guide plate is positioned above the screen plate, and the collection frame is positioned below the screen plate. The guide plate guides the material flow onto the screen plate, and solid waste particles smaller than the screen hole size fall through the screen plate into the collection frame below.
[0013] Preferably, the outer wall of the bottom of the feeding pipe is fixedly connected to the outer wall of the top of the screening box. The feeding pipe is located above the inlet, and the solid waste that has been broken up by the feeding structure enters the screening box through the inlet.
[0014] (III) Beneficial Effects
[0015] This utility model provides a sorting device for industrial solid waste screening. It has the following beneficial effects:
[0016] (i) The feeding structure is driven by a motor to rotate the rotating rod, which in turn drives the worm gear, connecting rod, turntable and impact plate to operate. This design can effectively break up clumps or agglomerates of industrial solid waste. Compared with the traditional direct feeding method, it avoids screening blockage and unevenness caused by material agglomeration, greatly improves the uniformity of materials entering the screening box, lays a solid foundation for subsequent screening, and significantly improves the overall sorting efficiency.
[0017] (ii) The screening box is driven by a motor to rotate a cam. The cam and the screen plate are pushed by the contact between the cam and the screen plate. With the reset action of the pressure spring, the screen plate makes stable reciprocating vibration on the slide bar. This vibration mode allows solid waste to jump and move fully on the screen plate, ensuring that solid waste particles smaller than the screen hole size can pass through the screen and fall into the collection frame more thoroughly. The opening and closing plate on the side of the screening box can be easily opened after screening, and the operator can easily scrape out and collect the material larger than the screen hole size left on the screen plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 This utility model provides a technical solution: a sorting device for industrial solid waste screening, comprising: a screening box 1, a screen plate 2 slidably connected to the inner wall of the screening box 1, a collection frame 4 slidably connected to the inner wall of the bottom of the screening box 1, and a feeding structure 3, the outer wall of the bottom of the feeding structure 3 being fixedly connected to the outer wall of the top of the screening box 1; the feeding structure 3 includes a feeding pipe 31, a rotating rod 32 rotatably connected to the inner wall of the side of the feeding pipe 31, a worm gear 33 fixedly connected to the outer wall of the rotating rod 32, a motor 34 rotatably connected to the outer wall of the rotating rod 32 away from the worm gear 33, a connecting rod 35 rotatably connected to the inner wall of the top of the feeding pipe 31, a worm wheel 36 fixedly connected to the outer wall of the top of the connecting rod 35, a turntable 37 fixedly connected to the outer wall of the bottom of the connecting rod 35, a striking plate 38 fixedly connected to the outer wall of the turntable 37, and a feed guide plate 39 fixedly connected to the outer wall of the feeding pipe 31.
[0026] The outer wall of the motor 34 is fixedly connected to the outer wall of the feeding pipe 31. The outer wall of the worm 33 meshes with the outer wall of the worm wheel 36. The striking plates 38 are arranged in a ring around the central point of the turntable 37. The motor 34 drives the rotating rod 32 to rotate, and the worm 33 on the rotating rod 32 rotates accordingly. Since the worm 33 meshes with the worm wheel 36, the rotation of the worm 33 drives the worm wheel 36 to rotate, which in turn drives the connecting rod 35 to rotate. The turntable 37, which is fixedly connected to the bottom of the connecting rod 35, also rotates together.
[0027] The screening box 1 has a feed inlet 11 on the outer wall of the top. The outer wall of the side of the screening box 1 is symmetrically and fixedly connected with a slide rod 12. The outer wall of the slide rod 12 is fixedly connected with a baffle 13. The outer wall of the baffle 13 is fixedly connected with a pressure spring 14. The inner wall of the screening box 1 is rotatably connected with an opening and closing plate 15. The outer wall of the screening box 1 away from the slide rod 12 is fixedly connected with a support plate 16. The outer wall of the bottom of the support plate 16 is fixedly connected with a motor 17. The outer wall of the motor 17 is fixedly connected with a cam 18. The inner wall of the screening box 1 is symmetrically and fixedly connected with guide plates 19.
[0028] The outer wall of the slide rod 12 is slidably connected to the inner wall of the screen plate 2. The outer wall of the pressure spring 14 on the side away from the baffle 13 is fixedly connected to the outer wall of the screen plate 2. The cam 18 is fixedly connected to the rotating shaft on the motor 17. The outer wall of the cam 18 is slidably connected to the outer wall of the screen plate 2. When the motor 17 starts, its rotating shaft drives the cam 18 to rotate. During the rotation, the outer wall of the cam 18 continuously contacts and pushes the screen plate 2. The screen plate 2 slides on the slide rod 12. At the same time, because the screen plate 2 is close to the baffle 13, the pressure spring 14 is compressed. When the cam 18 rotates to a certain position and no longer exerts a pushing force on the screen plate 2, the elastic force of the pressure spring 14 causes the screen plate 2 to return to its original position. This process is repeated.
[0029] The guide plate 19 is positioned above the screen plate 2, and the collection frame 4 is positioned below the screen plate 2. The guide plate 19 guides the material flow to the screen plate 2, and solid waste particles smaller than the screen hole size of the screen plate 2 fall into the collection frame 4 below through the screen plate 2.
[0030] The outer wall at the bottom of the feeding pipe 31 is fixedly connected to the outer wall at the top of the screening box 1. The feeding pipe 31 is located above the inlet 11. Solid waste that has been broken up by the feeding structure 3 enters the screening box 1 through the inlet 11.
[0031] In use, industrial solid waste enters the screening box 1 through the feeding structure 3 and is screened by the screen plate 2 in the screening box 1. Solid waste particles smaller than the screen hole size of the screen plate 2 fall into the collection frame 4 below through the screen plate 2, completing the screening process. Materials larger than the screen hole size remain on the screen plate 2 and are cleaned and collected by the opening and closing plate 15 for further processing or discharge.
[0032] First, industrial solid waste enters the discharge pipe 31 through the feed guide plate 39. The motor 34 is started, and the motor 34 drives the rotating rod 32 to rotate. The worm 33 on the rotating rod 32 rotates accordingly. Since the worm 33 meshes with the worm wheel 36, the rotation of the worm 33 drives the worm wheel 36 to rotate, which in turn drives the connecting rod 35 to rotate. The turntable 37, which is fixedly connected to the bottom of the connecting rod 35, also rotates together. The striking plates 38 of the annular array on the outer wall of the turntable 37 continuously strike the falling industrial solid waste during the rotation process. This process can break up the clumps or lumps of solid waste, so that it can enter the screening box 1 more evenly for subsequent screening, avoiding the screening effect caused by the clumping of materials.
[0033] The solid waste, after being broken up by the feeding structure 3, enters the screening box 1 through the feed inlet 11. The motor 17 on the support plate 16 starts, and its shaft drives the cam 18 to rotate. During the rotation, the outer wall of the cam 18 continuously contacts the outer wall of the screen plate 2 and pushes the screen plate 2. The screen plate 2 slides on the slide rod 12. At the same time, because the screen plate 2 is close to the baffle 13, the pressure spring 14 is compressed. When the cam 18 rotates to a certain position and no longer pushes the screen plate 2, the elastic force of the pressure spring 14 makes the screen plate 2 return to its original position. This process is repeated, and the screen plate 2 reciprocates on the slide rod 12.
[0034] During the vibration of the screen plate 2, the solid waste continuously jumps and moves on the screen plate 2. The guide plate 19 above the screen plate 2 guides the material flow to the screen plate 2. Solid waste particles smaller than the screen hole size of the screen plate 2 fall into the collection frame 4 below through the screen plate 2, completing the screening process. Materials larger than the screen hole size remain on the screen plate 2. After screening is completed, the device stops. At this time, the opening and closing plate 15 on the side of the screening box 1 can be opened by the handle to scrape the larger materials off the screen plate 2 for collection, further crushing or discharge.
