Scraped car residue harmless treatment method based on residue separation

Abstract

The invention relates to the technical field of automobile scrap, in particular to a scrap automobile residue harmless treatment method based on residue separation, which comprises the following steps: S1, putting metal and plastic mixed residues of a scrap automobile into a pretreatment module for sorting, and collecting plastic residues in the metal and plastic mixed residues; s2, the residues are conveyed to a verification module to be subjected to metal verification; s3, the detected plastic residues are fed into a sorting module to be subjected to plastic category sorting according to the density; and S4, the plastic residues sorted according to the categories are subjected to harmless treatment or recycling according to a preset treatment mode. According to the method, the plastic residues in the scraped car residues are subjected to step-by-step sorting to separate the metal residues in the plastic residues, and the plastic residues with different densities are classified, collected and correspondingly treated by performing density sorting through the sorting module; and collection and utilization of the plastic residues in the scraped car residues are effectively achieved.

Description

technical field [0001] The invention relates to the technical field of scrapped automobile recycling, in particular to a method for harmless treatment of scrapped automobile residues based on residue separation. Background technique [0002] At present, the number of automobiles in my country is increasing day by day. According to reports, in 2020, the number of motor vehicles in my country will reach 372 million, of which 281 million are automobiles. According to the annual scrapping volume of about 7%, the weight of scrapped automobiles alone exceeds 28 million tons. For the increasingly serious problem of automobile scrapping, combined with the needs of global green environmental protection and energy conservation, automobile scrapped recycling technology and scrapped automobile resource recycling technology have become important issues in the field of automobile scrapping. [0003] Chinese Patent Publication No.: CN201810892113.5 discloses a method for recycling scrapped...

AI Technical Summary

Problems solved by technology

[0005] For this reason, the present invention provides a method for the harmless treatment of scrapped automobile residues based on residue separation, to overcome the problem in the prior art that plastic residues and metal residues in automobile residues cannot be completely separated, and to optimize the classification of plastic residues Collection makes recycling of end-of-life vehicle residues more targeted
