Description

Technical Field

[0001] This utility model relates to the technical field of plastic granule processing, and in particular to a mixing device for processing plastic granule raw materials. Background Technology

[0002] Plastic granules have a wide range of applications. In daily life, recycled granules can be used to manufacture various plastic bags, buckets, basins, toys, furniture, stationery, and other household items and plastic products. In the clothing industry, they can be used to manufacture clothing, ties, buttons, and zippers. In building materials, recycled plastic granules are used to produce wood-plastic composite profiles, which are used to manufacture various building components, plastic doors and windows, etc. In the chemical industry, they can be used to make reaction vessels, pipes, containers, pumps, valves, etc., in chemical production sites where corrosion and wear are a concern. Plastic granules refer to granular plastics, generally classified into more than 200 types, with thousands of subcategories. Common plastic granules include general-purpose plastics, engineering plastics, and specialty plastics. General-purpose plastics include polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, and polyurethane. Engineering plastics include nylon, polytetrafluoroethylene, polyoxymethylene, and polycarbonate. Filtration of raw materials is necessary during plastic processing.

[0003] Extensive research revealed that prior art publication number CN215849114U discloses a plastic particle filtering device, including a filter box. An electric motor is mounted on the top of the filter box, and a rotating rod is rotatably connected inside the filter box. The top of the rotating rod extends through the filter box and is fixedly connected to the output end of the electric motor. Two conical filter layers are rotatably connected inside the filter box. This invention uses a drive motor to move the two conical filter layers, grading plastic particles of different sizes while removing plastic residue. An air pump, in conjunction with an air pipe, assists in amplifying the airflow during filtration, keeping the plastic particles in a constant state of displacement and preventing accumulation and clogging. The graded plastic particles are discharged through two separate discharge pipes, while plastic residue is discharged through a waste discharge pipe. This design ensures the device is less prone to accumulation and clogging during plastic particle screening, resulting in high filtration efficiency and increased overall device efficiency.

[0004] In summary, existing filtration devices lack a proper stirring mechanism, resulting in poor filtration efficiency. Furthermore, the installation method of the filter screen is not detailed, and the typical installation method of the filter screen is highly fixed but has poor disassembly capability.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a plastic granule raw material processing and mixing device, which would have greater industrial application value. Utility Model Content
