Inclined plate type stainless steel broken material pneumatic sorting device and method

Abstract

The invention discloses an inclined plate type stainless steel broken material pneumatic sorting device and method. The device comprises a vibration feeding system used for vibrating and conveying mixed materials, an inclined plate conveying system for conveying the mixed materials, a stainless steel detecting system for detecting stainless steel, a stainless steel sorting system for sorting the stainless steel, a stainless steel material box used for receiving the sorted stainless steel, a non-metal material box used for receiving non-metal materials, and a control system used for controlling electromagnetic valves to be opened and closed according to electric signals sent by proximity sensors. By means of the inclined plate type stainless steel broken material pneumatic sorting device, the stainless steel can be conveniently, fast and efficiently recycled from the mixed materials of the stainless steel and the non-metal materials.

Description

technical field [0001] The invention belongs to the technical field of scrap metal recycling of scrapped automobiles, and in particular relates to a slant plate type pneumatic sorting device and method for stainless steel crushed materials. Background technique [0002] With the rapid development of science and technology, the use of stainless steel is increasing, and more and more scrap metal needs to be processed. If only the method of landfilling and discarding is used, it will not only pollute the environment, but also cause a lot of waste of resources, which is not advisable in today's situation where resources are increasingly scarce. However, metal waste often contains more plastic, glass and other non-metals, so a convenient and efficient equipment is needed to separate metal from waste. [0003] At present, the sorting technologies of stainless steel include color sorting, laser induction decomposition spectroscopy, eddy current sorting and other methods. Color so...

AI Technical Summary

Problems solved by technology

Color sorting technology selects stainless steel materials according to the color of the materials. In order to achieve a higher grade and recovery rate, this method requires several processes, and the sorting cost is very high. The disadvantage is that the color of stainless steel is similar to that of other materials, and the sorting is accurate. low rate

However, laser-induced decomposition spectroscopy is susceptible to the influence of metal surface components.

These two sorting methods will be limited when the metal surface is rusted, or painted, etc.

The eddy current separator is more effective for the separation of small particle metals, but the separation effect for large particle metals is poor
