Waste plastic cleaning and sorting device and technology

Abstract

The invention relates to a waste plastic cleaning and sorting device and technology, and belongs to the technical field of waste plastic comprehensive utilization. According to the technical scheme, the device is formed by series connection of three cleaning and sorting device bodies, a high-speed-rotating propeller is used, the acute waterflow turbulence is generated, impurities bonded on the waste plastic are separated, a screening plate is used for separating heavy-impurity plastic from the impurities, the heavy-impurity plastic and the impurities are conveyed out and are subject to treatment, a dial wheel is used for cleaning and sorting the little-impurity plastic from the waste plastic and then moving the little-impurity plastic out, power consumption is reduced, the little-impurity plastic, the heavy-impurity plastic and the impurities are thoroughly separated, the waste plastic is sufficiently reutilized, the waste is turned into wealth, environment pollutions are reduced, the power consumption is low, and the device and technology are easily used and popularized. The separated-out little-impurity plastic, the heavy-impurity plastic, the impurities and the like are comprehensively used, the environment pollution is reduced, and the repeated use value of the waste plastic is improved.

Description

technical field [0001] The invention relates to a cleaning and sorting equipment and process for waste plastics, belonging to the technical field of comprehensive utilization of waste plastics. Background technique [0002] At present, the prior art waste plastic cleaning and sorting equipment can only separate PE and PP which are lighter than water according to the specific gravity method, while PS, PVC, ABS and sand, glass, wood chips, pulp, etc. If they are mixed together, they cannot be cleaned and sorted, and cannot be reused, resulting in waste of resources and pollution of the environment. Moreover, the waste plastic cleaning and sorting equipment in the prior art has the disadvantages of large water consumption, large power consumption, and poor cleaning effect. Contents of the invention [0003] The purpose of the present invention is to provide a cleaning and sorting equipment and process for waste plastics, which can quickly classify PE, PP, which are lighter t...
