[0002] Plastic particles are the common name of plastic pellets, which are the raw materials for storing, transporting and processing plastics in semi-finished form. Plastic is a type of polymer material. Ethylene, propylene, vinyl chloride, styrene, etc. can be obtained from petroleum. The molecules of these substances can react with each other under certain conditions to form compounds with very large molecular weights, that is, polymers. Plastic particles need to be screened by a screening device before use.

[0003] When the common engineering plastic particle screening device is in use, its structure is relatively simple and its functions have certain limitations. Usually, when the screening device screens plastic particles, it uses a vibration motor and a filter screen for screening, with low efficiency. In addition, during screening, some plastic particles will get stuck in the pores of the filter screen, which is inconvenient to clean and affects the screening efficiency, bringing certain adverse effects to the using process. Therefore, we propose an engineering plastic particle screening device. Content of the Utility Model
