Broken plastic stirring device

Abstract

The invention relates to the technical field of waste plastic reprocessing equipment and particularly discloses a broken plastic stirring device. The broken plastic stirring device comprises a material cylinder, a feeding device, a stirring device body, an air uniformizing device and a temperature increasing device. The feeding device comprises a feeding bin, feeding hoppers, a first screw rod, asecond screw rod, a first spiral blade and a second spiral blade, and the spiral direction of the second spiral blade is opposite to the spiral direction of the first spiral blade. The stirring devicebody comprises a stirring motor, a stirring shaft, a spiral stirring blade and a spreading disk, and the spiral stirring blade is of a structure gradually becoming larger from bottom to top on the stirring shaft. The air uniformizing device comprises a main air pipe, annular air uniformizing pipes and gourd-shaped air uniformizing nozzles. The temperature increasing device comprises a shell, twosupporting plates, insulating rings and heating pipes. The broken plastic stirring device has the characteristics that stirring is uniform, the manpower cost and the material resource cost are both low, and dust and moisture are easy to discharge.

Description

Technical field [0001] The invention relates to the technical field of waste plastic reprocessing equipment, in particular to a crushing plastic stirring device. Background technique [0002] HDPE (High Density Polyethylene) particles have a wide range of applications in our lives. In industry, HDPE particles can be used to make pumps, pipes, containers, 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 films, fertilizer packaging bags, pumping pipes and cement packaging In terms of construction materials, HDPE particles can be used to make various structural components, plastic doors and windows, and stucco buckets; in daily life, HDPE particles can be used to make all kinds of plastic bags, toys, furniture, buckets, pots and stationery In the dressing industry, HDPE particles can be used to make dressings, ties, buttons and zippers. [0003] The raw materials used in the ...

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 device just pours all the raw materials into the material barrel, and the motor drives the stirring paddle in the material barrel to stir, and the stirring is not uniform enough. , the volume of the barrel in the stirring device is usually large, and additional lifting equipment is required to send the raw materials to the upper inlet of the barrel, which makes the cost of manpower and material resources higher. The stirring is carried out in a relatively closed environment. The air circulation inside the cylinder 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 for manufacturing HDPE granular raw materials has the problems of uneven stirring, high manpower and material costs, and difficult discharge of dust and moisture.
