[0002] Chlorinated polyethylene is an important synthetic plastic with a wide range of uses and applications. The production of chlorinated polyethylene requires the polyethylene raw material to be processed into a suitable particle form so that it can be used in the subsequent chlorination treatment. Therefore, the polyethylene crushing device used in the production of chlorinated polyethylene is an important process equipment.

[0034] Example 2:

[0035] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0036] like Figure 2 and Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the bottom end surface of the fixed grid 4 is fitted with the top surface of the fixed plate 3, the bottom end surface of the drain pipe 5 is flush with the bottom end surface of the fixed grid 4, the first discharge pipe 6 is symmetrically distributed on both sides of the bottom of the fixed grid 4, the rotating shaft 9 is rotatably connected to the fixed plate 3 and the fixed grid 4, the rotating shaft 9 is connected to the center of the fixed plate 3, the second circular gear 11 is distributed at equal angles on the first circular gear 10, the second circular gear 11 corresponds to the connecting shaft 12 one by one, and a guide groove 13 is provided on the inner top surface of the device housing 1, the guide groove 13 is annular, and the top limit sliding connection of the connecting shaft 12 is connected in the guide groove 13, The bottom end of the connecting shaft 12 is rotatably connected to the first push plate 16, the bottom end face of the first push plate 16 is in contact with the top face of the fixed grid 4, the side end face of the first push plate 16 is in contact with the inner wall of the device housing 1, and an internal gear 31 is welded and fixed on the inner top face of the device housing 1, the internal gear 31 is meshed with the second circular gear 11, and the servo motor 8 drives the first circular gear 10. Combined with the second circular gear 11 and the internal gear 31, it can drive each connecting shaft 12 to automatically revolve during the rotation process. Through each silicone rod 14 and the flexible brush 15, the polyethylene raw material in various places inside the device can be stirred and cleaned, and combined with purified water, the polyethylene raw material can be comprehensively and efficiently cleaned.

[0037] like Figure 2 and Figure 6 As shown, as a preferred embodiment, on the basis of the above method, the transmission shaft 19 is further rotatably connected to the inner wall of the device housing 1, and a protective frame 21 is welded and fixed to the bottom end surface of the fixed plate 3. The protective frame 21 is rotatably connected to the rotating shaft 9 and the transmission shaft 19, and the rotating shaft 9 is rotatably connected to the screening mesh plate 23. The worm gears 18 are symmetrically distributed on both sides of the worm 17, and the worm gears 18 correspond one-to-one to the transmission shaft 19. The crushing rollers 20 are symmetrically distributed on both sides of the transmission shaft 19. Under the rotation of the rotating shaft 9, the worm gears 18 engaged on both sides can be driven by the worm 17 to rotate stably. At this time, under the rotation of the worm gears 18 on both sides, the corresponding transmission shafts 19 can be driven to rotate toward the middle at the same time, and then the adjacent crushing rollers 20 can be driven to rotate toward the middle at the same time, so that the discharged polyethylene raw materials can be stably crushed.

[0038] like Figure 2 and Figure 5As shown, as a preferred embodiment, on the basis of the above method, further, the second pusher plate 22 is distributed at equal angles on the rotating shaft 9, the bottom end face of the second pusher plate 22 is in contact with the top end face of the screening mesh plate 23, the top end face of the screening mesh plate 23 is flush with the bottom end face of the first through groove 25, and the first through groove 25 is symmetrically distributed on both sides of the device housing 1. The screening mesh plate 23 can be used to screen the polyethylene after the crushing process, and the large-particle polyethylene raw materials that fail the crushing process will be pushed to the side by the second pusher plate 22 in each rotation process to avoid the accumulated large particles clogging the screening mesh plate 23 and affecting the screening effect.

[0039] like Figure 2 、 Figure 3 and Figure 8 As shown, as a preferred embodiment, on the basis of the above method, further, the length and width of the first through slot 25 are respectively equal to the length and width of the second through slot 30, and the collection box 29 and the magnetic frame 28 are connected by magnetic adsorption. The side end faces of the collection box 29 and the side end faces of the magnetic frame 28 are both in contact with the outer wall of the device housing 1, and the threaded rod 27 is connected to the top middle part of the magnetic frame 28. After all the polyethylene raw materials are crushed, the collection box 29 on the magnetic frame 28 is driven downward by rotating the threaded rod 27 until the second through slot 30 is aligned with the first through slot 25. At this time, the large-particle polyethylene raw materials that fail the crushing process will automatically enter the collection box 29 through the first through slot 25 and the second through slot 30 to complete automatic collection. Subsequently, the collection box 29 can be used to conveniently transport the large-particle polyethylene raw materials, ensuring the convenience and efficiency of the subsequent crushing process.

[0040] Specifically, when the polyethylene crushing device for producing chlorinated polyethylene is used: first, the staff can transport the polyethylene raw material into the device shell 1 through the feed port 2. At this time, the polyethylene raw material can be stably accumulated on the fixed grid 4. Then the staff can transport the clean water needed to be used into the device shell 1. After the loading work is completed, the staff can turn on the servo motor 8 on the device shell 1. At this time, under the driving action of the servo motor 8, the first circular gear 10 on the rotating shaft 9 can be driven to rotate stably. At this time, under the rotation action of the first circular gear 10, the second circular gear 11 connected by thread can be driven to rotate stably. During the rotation process of the second circular gear 11, through the meshing connection with the internal gear 31, the second circular gear 11 rotates during the self-rotation process. In the embodiment, the self-rotating second circular gear 11 can perform circular motion in the internal gear 31, that is, revolution. At this time, the self-rotating second circular gear 11 can automatically revolutionize. Therefore, the second circular gear 11 can drive the connecting shaft 12 to revolve along the trajectory of the guide groove 13 during the self-rotation process. At this time, under the action of the movement of each connecting shaft 12, the polyethylene raw material at various locations inside the device can be stirred and cleaned through each silicone rod 14 and the flexible brush 15. Combined with purified water, the polyethylene raw material can be comprehensively and efficiently cleaned to remove pollutants and impurities on the surface of the polyethylene raw material. After the cleaning work is completed, the staff can open the first discharge pipe 6 on the drain pipe 5. At this time, the used waste water can flow through the fixed grid 4 to the drain pipes 5 on both sides, and then be discharged through the drain pipe 5.

[0041] Then the staff can open the solenoid valve 7 on the first discharge pipe 6, and during the rotation and revolution of each connecting shaft 12, the first pusher plate 16 connected to the bottom end can be driven to perform a smooth circular motion inside the device housing 1. At this time, under the action of the movement of the first pusher plate 16, the cleaned polyethylene raw material can be moved stably to the first discharge pipes 6 on both sides, and then the material can be stably discharged through the first discharge pipe 6 until all the polyethylene raw material is discharged through the first discharge pipe 6;

[0042] As can be seen from the drawings of the present application, the first discharge pipe 6 is located directly above the adjacent crushing rollers 20, so the polyethylene raw material discharged from the first discharge pipe 6 can stably fall between the adjacent crushing rollers 20, and during the discharge of the polyethylene raw material, the rotating shaft 9 is always in a rotating state. Therefore, under the rotation of the rotating shaft 9, the worm gears 18 engaged on both sides can be driven to rotate stably through the worm 17. At this time, under the rotation of the worm gears 18 on both sides, the corresponding transmission shafts 19 can be driven to rotate toward the middle at the same time, and then the adjacent crushing rollers 20 can be driven to rotate toward the middle at the same time, so that the discharged polyethylene raw material can be stably crushed, and then the crushed polyethylene raw material can stably fall onto the screening mesh plate 23, and the screening mesh plate 23 can be used to screen the crushed polyethylene raw material;

[0043] The qualified polyethylene raw materials can continue to fall through the screening mesh plate 23 and be discharged through the second discharge pipe 24. Subsequently, the qualified polyethylene raw materials can be transported to the next process for subsequent processing by using the transfer equipment, while the large-particle polyethylene raw materials that fail to meet the crushing requirements will remain on the screening mesh plate 23. At this time, under the continuous rotation of the rotating shaft 9, the second pusher plates 22 can be driven to move synchronously, thereby continuously shifting the large-particle polyethylene raw materials that fail to meet the crushing requirements. At this time, under the action of centrifugal force, the large-particle polyethylene raw materials that fail to meet the crushing requirements will automatically move to the inner side of the device housing 1. At this time, the first through groove 25 and the second through groove 30 are not aligned, so the large-particle polyethylene raw materials that fail to meet the crushing requirements will temporarily remain on the inner side of the device housing 1, preventing the qualified polyethylene raw materials from mistakenly entering the collection box 29.

[0044] After all the polyethylene raw materials are crushed, the staff can rotate the threaded rod 27 on the support plate 26. At this time, under the action of the threaded rotation of the threaded rod 27, the magnetic frame 28 connected to the bottom end can be pushed to move downward stably. At this time, under the action of the movement of the magnetic frame 28, the collection box 29 can be driven to move downward synchronously until the second through slot 30 on the collection box 29 is aligned with the first through slot 25 on the device housing 1. At this time, under the continuous rotation of each second push plate 22, the large particles of polyethylene raw materials that fail to meet the crushing requirements will pass through the first through slot 25 and The second through slot 30 is pushed into the collection box 29 to complete the automatic collection work. After the collection work is completed, the magnetism of the magnetic frame 28 is utilized to pull the collection box 29 to separate it from the magnetic frame 28, so that the collection box 29 can be easily disassembled. Then the staff can use the collection box 29 to conveniently transport the large-particle polyethylene raw materials, ensuring the convenience and efficiency of the subsequent crushing processing work. Similarly, the collection box 29 can be easily installed by simply inserting it into the magnetic frame 28, ensuring the stability of the subsequent working state of the collection box 29.

[0045] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements that do not deviate from the spirit and scope of the utility model are included in the scope of the claims of the present invention.
