Waste vehicle plastic recovery method

Abstract

The invention belongs to the technical field of plastic recovery and particularly provides a waste vehicle plastic recovery method. The method adopts a screening device, and the screening device comprises a box body, a feeding port and a sorting module. The sorting module comprises fixed plates, electromagnets, a swing plate, a swing unit, a storage module and a controller. A set of electromagnetsare arranged on the fixed plates at intervals, the V-shaped swing plate is arranged between the two fixed plates, and the swing unit comprises a cam, a support and a guide rod. The cam rotates to drive the swing plate to perform reciprocating swing. The controller is installed on one side of the top and bottom of the box body and used for controlling intermittent powering on of the electromagnets. The storage module is installed under the fixed plates and used for storing plastics and metals screened by the sorting module. The screening device adopted by the waste vehicle plastic recovery method performs adsorption through the electromagnets, separates out metals in a mixed material, corresponding plastics and metals are separated through the storage device arranged under the screening device, and plastic recovery is achieved.

Description

technical field [0001] The invention belongs to the technical field of plastic recycling, in particular to a method for recycling plastics from waste vehicles. Background technique [0002] As the consumption of plastic products continues to increase, waste plastics are also increasing. At present, my country's waste plastics are mainly plastic films, plastic yarns and woven products, foam plastics, plastic packaging boxes and containers, daily-use plastic products, plastic bags and agricultural mulch films. In addition, the annual consumption of plastics for automobiles in my country has reached 400,000 tons, and the annual consumption of plastics for electronic appliances and home appliances has reached more than 1 million tons. These products have become one of the important sources of waste plastics after they are scrapped. [0003] As of the end of 2013, the number of automobiles in my country has reached 137 million. According to the annual decommissioning or scrappin...

AI Technical Summary

Problems solved by technology

[0004] In the dismantling process of scrapped cars, the car frame and some of its interiors are generally unable to be finely disassembled. Generally, it is first crushed by a shredder, and the metal and plastic are crushed into small pieces, and then the plastic and metal pieces are crushed. Separation; metal fragments and plastic fragments are mixed together, it is not easy to separate, and the separation by manual sorting is low in efficiency, and the fragments are easy to scratch the operator; restricting the efficiency of automobile waste plastic recycling
