Stirring equipment for broken plastic

Abstract

The invention relates to the technical field of waste plastic reprocessing equipment, and particularly relates to stirring equipment for broken plastic. The stirring equipment for the broken plastic comprises a charging barrel, a feeding device, a material stirring device, an air equalizing device and a heating device. The feeding device comprises a feeding bin, a feeding hopper, a first screw rod, a second screw rod, a first screw blade and a second screw blade, wherein the screw direction of the second screw blade is opposite to that of the first screw blade. The material stirring device comprises a stirring motor, a stirring shaft and the screw stirring blades. The air equalizing device comprises a main air pipe, an annular air equalizing pipe and a gourd-shaped air equalizing nozzle. The heating device comprises a shell, two supporting plates, an insulating ring and a heating pipe. The stirring equipment for the broken plastic has the characteristics of low labor and material costand easy discharging of dust and moisture.

Description

technical field [0001] The invention relates to the technical field of waste plastic reprocessing equipment, in particular to a crushing plastic mixing equipment. 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. [0003] The raw materials u...

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. At present, the volume of the material cylinder in the mixing device is usually large, and additional lifting equipment is needed to send the raw materials to the upper inlet of the material cylinder, which makes manpower The material and material costs are high, and the mixing is carried out in a relatively closed environment. The air circulation inside the barrel is not smooth, which is not conducive to the discharge of dust and moisture generated during the mixing process of raw materials.

[0004] Therefore, the existing stirring device used to manufacture HDPE granular raw materials has the problems of high manpower and material costs, and difficult discharge of dust and moisture.
