[0002] Polyvinyl chloride plastic is made by the polymerization of vinyl chloride monomer and is one of the commonly used thermoplastic plastics. Pure polyvinyl chloride resin is a hard thermoplastic substance. Its decomposition temperature is very close to the plasticizing temperature, and its mechanical strength is poor. Polyvinyl chloride resin cannot be used to plasticize products. Plasticizers, stabilizers, fillers, etc. must be added to improve the performance to make polyvinyl chloride plastic, and then processed into various products. Polyvinyl chloride is divided into hard polyvinyl chloride and soft polyvinyl chloride according to the amount of plasticizer added. Polyvinyl chloride powder is a common plastic raw material with good heat resistance, corrosion resistance and mechanical properties. It is widely used in plastic products, building materials, wires and cables and other fields.

[0020] Among them, a driving motor 8 is fixedly connected to the upper end of the top cover 7, and a driving rod 9 is fixedly connected to the end of the output shaft of the driving motor 8. A separation disk 13 is arranged in the silo 1, and a separation groove is penetrated at the upper end of the separation disk 13. The separation groove is connected to the driving rod 9 through a transmission device. The transmission device includes a rotating rod 11 fixedly connected to the bottom of the separation groove, and a connecting groove is penetrated at the upper end of the rotating rod 11. The driving rod 9 is slidably connected in the connecting groove. Limiting rods 10 are fixedly connected to the opposite side walls of the driving rod 9, and limiting grooves are penetrated at the opposite inner walls of the connecting groove at corresponding positions. The two limiting rods 10 are slidably connected in the two limiting grooves respectively.

[0021] Specifically, a separation device is fixedly connected to the inner bottom of the separation groove, and the separation device includes a plurality of cutting knives 14 fixedly connected to the inner bottom of the separation groove. The plurality of cutting knives 14 are arranged in the separation groove at equal intervals along the circumference of the separation groove. The upper ends of the plurality of cutting knives 14 are designed with cutting surfaces, and a plurality of filter holes 15 are penetrated through the inner bottom of the separation groove.
