Crushed plastic stirring device good in air circulation effect

Abstract

The invention relates to the technical field of waste plastic reprocessing equipment, and particularly discloses a crushed plastic stirring device good in air circulation effect. The crushed plastic stirring device comprises a material barrel, a feeding device, a mixing device and an air homogenizing device. The feeding device comprises a feeding bin and a feeding hopper. A feeding motor is arranged at the side portion of the feeding bin. A spiral feeding rod is arranged on an output shaft of the feeding motor. The mixing device comprises a stirring motor and a spiral stirring rod. The air homogenizing device comprises a main air pipe vertically arranged on the inner wall of the material barrel and a plurality of annular air homogenizing pipes, the annular air homogenizing pipes are attached to the inner wall face of the material barrel, the main air pipe is provided with a plurality of connecting holes, and air inlets of the annular air homogenizing pipes are connected with the connecting holes through outer threaded pipes. The annular air homogenizing pipes are provided with a plurality of air homogenizing holes pointing at the centers of the annular air homogenizing pipes. The positions of the air homogenizing holes are provided with calabash-shaped air homogenizing nozzles, and a ventilation pipeline is connected with an air inlet of the main air pipe. The crushed plastic stirring device has the beneficial effects that inner air circulation is smooth, and dust and moisture are likely to be discharged.

Description

technical field [0001] The invention relates to the technical field of waste plastic reprocessing equipment, in particular to a broken plastic stirring device with good air circulation effect. Background technique [0002] HDPE (High Density Polyethylene) particles are widely used in our lives. In industry, HDPE particles can be used to make pumps, pipes, containers and valves, etc., and can be used in chemical production sites that deal with corrosion and wear; in agriculture, HDPE particles can be used to make agricultural film, fertilizer packaging bags, water pipes and cement packaging Bags, etc.; in terms of building materials, HDPE particles can be used to make various building components, plastic doors and windows and plaster buckets, etc.; in daily life, HDPE particles can be used to make various plastic bags, toys, furniture, barrels, basins and stationery etc.; in the cosmetics industry, HDPE particles can be used to make cosmetics, ties, buttons and zippers, etc....

AI Technical Summary

Problems solved by technology

[0003] The raw materials used in the manufacture of HDPE particles are usually PP (polypropylene), PE (polyethylene) and PET (polyethylene terephthalate resin). In order to protect the environment, the country encourages the recycling of waste plastics, so in When manufacturing HDPE pellets, new materials and old materials will be properly used together, and appropriate proportions of PP, PE and PET crushing materials will be selected according to customer requirements. For different types of plastics, appropriate proportions of new materials and old materials will also be selected. Put the final selected raw materials into the mixing device for mixing. The current mixing is carried out in a relatively closed environment. The air circulation inside the barrel is not smooth, which is not conducive to the mixing process of the raw materials. Emission of dust and moisture generated

[0004] Therefore, the existing stirring device used to manufacture HDPE granular raw materials has the problems of poor internal air circulation and difficult discharge of dust and moisture.
