A cooling component 6 is arranged on the top of the base 1 near the screening box 2. The cooling component 6 includes a bracket 601 fixedly arranged on the top of the base 1 by bolts. Two groups of cooling fans 602 are fixedly arranged on the top of the bracket 601. The bottom ends of the cooling fans 602 are all plugged with air outlets 603. Starting the cooling fans 602 generates cold air that is blown out from the air outlets 603 to cool down the PVC particles. The convenience of cooling PVC particles is improved. A dredging component 3 is arranged on the side wall of the screening box 2. The dredging component 3 includes a servo motor 301 fixedly arranged on the side wall of the screening box 2. A threaded rod 302 is fixedly arranged at the output end of the servo motor 301. A screw rod slide 304 is threadedly connected to the outer surface of the threaded rod 302. A slider 303 is sleeved on the outer surface of the screw rod slide 304. A brush 305 is installed on the top of the slider 303. A notch 14 is opened near the bottom end of the brush 305. A slot three 15 is provided for the slider 303 to slide. By starting the servo motor 1 301, the threaded rod 302 and the screw slide 304 can be driven to rotate to push the slider 303 and the brush 305 to move horizontally. The bottom end of the slider 303 is adapted to the internal size of the slot three 15 to limit the lateral displacement of the slider 303, thereby improving the stability of the movement of the slider 303, and making the brush 305 made of nylon abut against the bottom end of the screen plate 4 for dredging, thereby improving the screening quality and efficiency of the screen plate 4.

[0020] A slot 8 is provided on the surface of the base 1, and a guide plate 7 is fixedly provided on the surface of the base 1 near the slot 8. The qualified PVC particles screened by the sieve plate 4 are received through the guide plate 7. The top of the guide plate 7 is clamped on the bottom end of the screening box 2, which improves the convenience of the PVC particles entering the slot 8. A conveying frame 10 is fixedly provided on the bottom end of the base 1 near the slot 8. The inner rotation of the conveying frame 10 is connected to a spiral conveying rod 9. A servo motor 2 13 is fixedly provided on the side wall of the conveying frame 10. The output end of the servo motor 2 13 is fixedly connected to the end of the spiral conveying rod 9.

The slot 14 can be opened by rotating the servo motor 13 to facilitate the cleaning of accumulated waste.

[0022] Working principle: When the PVC particle conveying and cooling device is in use, the operator first connects an external power supply and pours the PVC particles into the top of the screening box 2. By starting the two vibration motors 5, the screening box 2 and the screen plate 4 can be driven to vibrate, and unqualified waste materials fall from the screen plate 4 to the inside of the slot 2 14 to complete collection. As the screening box 2 vibrates, the screened PVC particles fall from the guide plate 7 to the inside of the slot 1 8, and then the servo motor 2 13 is started to drive the spiral conveying rod 9 to rotate, so that the PVC particles are stably conveyed. When the surface of the screen plate 4 is blocked, causing some unqualified particles to pass through the screen plate smoothly, the servo motor 1 301 can be started to drive the threaded rod 302 and the screw slide 304 to rotate, and the slider 303 and the brush 305 are pushed to move horizontally. The bottom end of the slider 303 is adapted to the internal size of the slot 3 15, which improves the stability of the movement of the slider 303. The brush 305 is made of nylon and abuts against the bottom end of the screen plate 4 for dredging, thereby improving the quality and efficiency of the screening of the screen plate 4.

[0023] Secondly, the screening box 2 is made of stainless steel and is fixedly connected to form an integrated structure. The second slot 14 is opened just below the screen plate 4 to prevent unqualified screens from scattering when they fall, thereby improving the stability of waste receiving. The second slot 14 can be opened by rotating the servo motor 13 to facilitate cleaning of accumulated waste.
