Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 As shown, a cooling device for the production of chlorinated polyvinyl chloride includes a box body 1. An installation frame 2 is fixed to the inner wall of the box body 1. A placement box 3 is arranged on one side of the installation frame 2. The chlorinated polyvinyl chloride to be cooled is stored in the placement box 3. A drive box 4 is arranged on one side of the box body 1. A motor 5 is installed on one side of the drive box 4. The motor 5 is fixedly connected to a drive rod 6. There are two groups of drive rods 6, and the two groups of drive rods 6 are connected by a belt drive. A drive block 7 is fixedly connected to the outer side of the drive rod 6. The placement box 3 is struck by the drive block 7 to turn the materials inside the placement box 3, improving the subsequent cooling effect. A transmission mechanism 8 is arranged inside the box body 1. A stirring rod 9 is arranged on the top of the transmission mechanism 8. The stirring rod 9 can be driven to rotate by the transmission mechanism 8, and the materials can be stirred by the stirring rod 9 to avoid the problem of material accumulation. A cooling box 10 is arranged on the top of the box body 1. A ventilation opening 11 is arranged on the top of the cooling box 10. A mounting seat 12 is fixedly connected to the top of the cooling box 10. A filter plate 13 is slidably connected to the inner wall of the mounting seat 12. The dust entering the ventilation opening 11 can be filtered by the filter plate 13 to avoid the problem of dust in the cooling air. An air pump 14 for cooling the materials is installed inside the cooling box 10. A box door 25 is arranged on one side of the box body 1. A material taking door 26 is arranged on one side of the placement box 3.

[0024] A connecting plate 15 is fixedly connected to the outer side of the placement box 3. A limiting rod 16 is fixedly connected to the inner wall of the mounting bracket 2. The outer side of the limiting rod 16 is slidably connected to the inner wall of the connecting plate 15. A spring 17 is arranged on the outer side of the limiting rod 16. Start the motor 5 to drive the driving rod 6 to rotate, so that the driving block 7 strikes the placement box 3, causing the placement box 3 to move upward, making the connecting plate 15 slide on the outer side of the limiting rod 16, causing the spring 17 to contract. When the spring 17 resets, it drives the connecting plate 15 and the placement box 3 to reset. Repeating the above process drives the placement box 3 to vibrate, causing the internal materials to be turned over, facilitating the subsequent cooling of the bottom materials and improving the cooling uniformity. A rotating rod 18 is rotatably connected to the bottom of the inner cavity of the box body 1. The outer side of the rotating rod 18 is rotatably connected to the inner wall of the placement box 3 through a bearing, and the placement box 3 can slide on the outer side of the rotating rod 18. A support block 19 is fixedly connected to the top of the rotating rod 18. The stirring rod 9 is fixed to the outer side of the support block 19. The transmission mechanism 8 includes a worm gear 81 fixed to the outer side of the rotating rod 18. A worm 82 is meshed with the outer side of the worm gear 81. The outer side of the worm 82 is connected to the outer side of the driving rod 6 through a belt drive. One end of the worm 82 is rotatably connected to the inner wall of the box body 1. When the driving rod 6 rotates, it drives the worm 82 to rotate, causing the worm gear 81 to drive the rotating rod 18 to rotate, so that the stirring rod 9 stirs the materials, avoiding the problem of material accumulation and further improving the cooling uniformity.

[0025] A guide rod 20 is fixedly connected to the inner wall of the mounting seat 12. A cleaning plate 21 is slidably connected to the outer side of the guide rod 20. The cleaning plate 21 can be used to clean the dust on the surface of the filter plate 13, avoiding the blockage of the filter plate 13. A partition plate 22 is fixedly connected to the inner wall of the cooling box 10. The air inlet end of the air pump 14 is communicated with the partition plate 22 through a pipeline. An air outlet pipe 23 is arranged at the air outlet end of the air pump 14. A plurality of air outlet heads 24 are arranged on the outer side of the air outlet pipe 23.

[0026] Working principle: When this device is in use, the chlorinated polyvinyl chloride to be cooled is stored in the placement box 3. Start the air pump 14, and cool the materials inside the placement box 3 through the air outlet pipe 23 and the air outlet heads 24. The filter plate 13 can filter the dust entering the ventilation opening 11, avoiding the problem of dust in the cooling air. The cleaning plate 21 can clean the dust on the surface of the filter plate 13, avoiding the blockage of the filter plate 13. Start the motor 5 to drive the driving rod 6 to rotate, so that the driving block 7 strikes the placement box 3, causing the placement box 3 to move upward, making the connecting plate 15 slide on the outer side of the limiting rod 16, causing the spring 17 to contract. When the spring 17 resets, it drives the connecting plate 15 and the placement box 3 to reset. Repeating the above process drives the placement box 3 to vibrate, causing the internal materials to be turned over, facilitating the subsequent cooling of the bottom materials and improving the cooling uniformity. When the driving rod 6 rotates, it drives the worm 82 to rotate, causing the worm gear 81 to drive the rotating rod 18 to rotate, so that the stirring rod 9 stirs the materials, avoiding the problem of material accumulation and further improving the cooling uniformity.
