Sorting and crushing device for recycling waste plastics

Abstract

The invention discloses a sorting and crushing device for recycling waste plastics. The sorting and crushing device comprises a bottom frame; crushed plastic fragments are cleaned by arranging a cleaning box; the plastic fragments are fully stirred by utilizing the reverse rotation of an auger and a drying drum; mixed label sticker fragments are blown off while the plastic products are dried by warm air flow; through impurity removal treatment, the purity of the waste plastic fragments and the plastic treatment efficiency are improved, and the situation that the quality of materials obtained after waste plastic regeneration is not high is avoided; a rotary disc and a first screening plate are arranged, and an auger is used for providing power to drive the rotary disc to rotate; and the first screening plate is driven to swing up and down under cooperation of a guide pin and a swing block. The waste plastic screening efficiency is improved; the recycling time is saved; meanwhile the problem that the fragments are accumulated on the surface of the first screening plate is avoided; and the whole device is simple in structure and convenient to use, and can improve the recycling efficiency and the quality of recycled plastic fragments.

Description

Technical field [0001] The present invention relates to a sorting apparatus pulverizing, classifying pulverized in particular to a device for recycling waste plastics. Background technique [0002] As plastic product consumption is increasing, waste plastics is also increasing. Waste plastics mainly for the plastic film, plastic filament and woven goods, foam, plastic packaging and containers, household plastic products, like plastic bags and agricultural mulch film. [0003] Since the plastic article has a corrosion resistant, easily degradable properties, arbitrarily discarded plastic products will remain in the environment for a long time, cause serious environmental pollution ecology, it is necessary for recycling plastic products, the prior art plastics grinding sorting apparatus crushed plastic pieces no washing and cleaning, resulting in a subsequent process step complicated plastics recycling, nor in the mixed plastic pieces of the label stock removal, the quality of the ...

AI Technical Summary

Problems solved by technology

[0006] (1) How to clean the broken plastic fragments by setting up the cleaning box, and use the reverse rotation of the auger and the drying cylinder to fully stir the plastic fragments, and blow off the mixed particles while drying the plastic products with warm air Fragments of labels and stickers solve the problem of low quality of waste plastics after regeneration due to lack of cleaning and impurity removal in the prior art;

[0007] (2) How to set the turntable and the first sieve plate, use the auger to provide power, drive the turntable to rotate, and drive the first sieve plate to swing up and down under the cooperation of the guide pin and the swing block, so as to solve the screening efficiency of the existing sieve device The problem that it is not high and debris is easy to form accumulation
