Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle production, in particular to a plastic particle preheating device. Background Art

[0002] Recycled plastic particles have a wide range of applications. In terms of building materials, the derivatives of recycled plastic particles, plastic wood profiles, are used to manufacture various building components, plastic doors and windows, etc. In the chemical industry, they can be used to make reactors, pipes, containers, pumps, valves, etc., and are used in chemical production sites to solve corrosion and wear. In agriculture, they can be used to make agricultural films, water pipes, agricultural machinery, fertilizer packaging bags, and cement packaging bags. In addition, recycled particles are also widely used in the electrical industry and the telecommunications industry.

[0003] When an existing plastic particle preheating device is used, the plastic particles are preheated. Since a large number of plastic particles enter the device at one time, the plastic particles are piled up together, making it difficult to separate the particles, thereby deteriorating the preheating effect. In addition, there is a lack of a stirring device during the preheating of the particles, which easily causes adhesion between the particles. Utility Model Content
