Embodiment Construction

[0011] The invention provides a crushing and sorting process for scrapped automobile bodies, comprising the following steps:

[0012] Step 1: Use two-stage crushing to gradually crush the scrapped car body to a predetermined size;

[0013] Step 2: Use negative pressure-cyclone separation process, magnetic separation process, eddy current separation process and drum screening process to separate light substances, magnetic metals, non-ferrous metals, fine powder substances, glass, rubber and Plastic separation and recycling.

[0014] The two-stage crushing methods are respectively primary crushing and fine crushing.

[0015] In the negative pressure-cyclone separation process, the feed inlet of the negative pressure-cyclone separation system is closely connected with the secondary crushed material outlet.

[0016] The drum screening process uses secondary screening. The secondary screen first passes through a fine mesh with a sieve aperture of 1-4mm to sieve out the finer part...

Abstract

The invention discloses a crushing and sorting process of a scrapped car body. The crushing and sorting process comprises the following steps of (1) gradually crushing the scrapped car body into preliminary dimensions in a two-stage crushing mode; (2) respectively separating and recycling light substances, magnetic metals, non-ferrous metals, micro powder substances, glass, rubber and plastic in sequence after the car body is crushed by adopting a negative pressure-cyclone separation process, a magnetic sorting process, an eddy current sorting process and a roller screening process. Accordingto the crushing and sorting process, the scrapped car body is crushed and sorted in a two-stage crushing and multi-sorting mode. The requirement of disassembling operation of an enterprise for disassembling the scrapped car body is fully satisfied, and the crushing and sorting process is an initiative technological process in the domestic existing same disassembling industry.

Description

technical field [0001] The invention relates to the field of scrapped automobile processing, in particular to a crushing and sorting process for 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, the car body is first divided by flame cutting, and...
