Embodiment Construction

[0018] Referring to the accompanying drawings, the crushing and sorting process of the scrapped automobile body of the present invention is as follows: the scrapped automobile body is put into the feed hopper of the primary crusher through the elevator, and the primary crusher adopts a double-shaft shredder to crush the automobile body into strips. Fragments, generally between 5-20cm×20-60cm in size, are sent to the secondary crusher through the primary belt conveyor. The secondary crusher adopts a vertical crusher to further crush the strip-shaped fragments into more The small fragments are generally 3-20cm in size, which is convenient for later selection. There is a negative pressure system at the outlet of the secondary crusher, which is used to send the crushed light materials to the cyclone separator and bag filter, and the heavier materials are sent to the magnetic separator by the secondary belt conveyor to separate the black materials. The metals are separated, and the...

Abstract

The invention discloses a fragmentation separation process flow for an end-of-life automobile body. The fragmentation separation process flow for an end-of-life automobile body can realize that an end-of-life automobile body is gradually fragmented into fragments having preset sizes by a two-step fragmentation method so that follow-up material sorting and recovery can be carried out conveniently. A sorting process of the fragmentation separation process flow for an end-of-life automobile body realizes separation and recovery of light materials, magnetic metal materials, non-ferrous metal materials, micro-powder materials, glass, rubber and plastic obtained by automobile body fragmentation by targetedly and orderly carrying out negative pressure-cyclone separation, magnetic sorting, eddy current sorting and drum screening according to material composition of the end-of-life automobile body. The fragmentation separation process flow for an end-of-life automobile body has the advantages of high automation degree, low noise, no dust, no exhaust gas, friendly work environment, high equipment sorting classification efficiency, simple and flexible configuration, and convenient management and maintenance. The fragmentation separation process flow for an end-of-life automobile body is a novel process flow used for an automobile disassembly industry of China.

Description

Technical field: [0001] The invention relates to the technical field of resource comprehensive utilization and environmental protection, in particular to a process flow for crushing and sorting scrapped automobile bodies. Background technique: [0002] With the continuous progress of modern human industrial civilization, the number of cars has increased sharply. By the end of 2009, the number of cars in my country has exceeded 70 million. According to relevant statistics, it is conservatively estimated that the number of scrapped cars in my country is about 4 million each year. The sharp increase in the number of scrapped vehicles has caused a series of problems such as comprehensive utilization of resources, environmental protection, technology and equipment. Scrapped cars are mainly composed of steel, non-ferrous metals, plastics, rubber, glass and other materials. The current domestic treatment method for scrapped cars is manual dismantling and manual sorting, that is, t...
