Sorting system and method for fragment raw materials of waste automobiles

Abstract

The invention discloses a sorting system and method for fragment raw materials of waste automobiles. The sorting system comprises a magnetic separator, a vibration sieve, a water separator, an airflow separator and an eddy current separator, wherein the vibration sieve comprises a first sieve section and a second sieve section which are sequentially connected; the water separator comprises a water separation hopper, a first conveyor belt, a second conveyor belt, a feed hopper, a back washing mechanism, a material separation mechanism and a drain mechanism, a gap is formed between the first conveyor belt and the second conveyor belt and matched with a discharge outlet of the feed hopper, and the feed hopper is connected with the second sieve section; the airflow separator is connected with the discharge end of the second conveyor belt; and the eddy current separator is connected with the discharge end of the airflow separator. The sorting method comprises the steps of magnetic separation, screening, water separation, air separation and eddy current separation which are sequentially conducted. According to the sorting system and method, the fragment raw materials are sequentially subjected to magnetic separation, screening, water separation, air separation and eddy current separation to achieve separation of the iron metal materials, removing of light impurities and drying and separation of nonferrous metal, the sorting efficiency is high, and the sorting cost is low.

Description

technical field [0001] The invention relates to a sorting technology, in particular to a sorting system and a sorting method for raw materials of scrap automobiles. Background technique [0002] After dismantling scrap cars and motorcycles, in order to recycle the useful steel in the disassembled parts, in order to facilitate recycling, the above parts are generally cut into crushed raw materials with a certain particle size, and then the crushed raw materials are Sponge, cloth, light plastic, sediment and other impurities in the machine are separated from the metal material, and the metal material is separated to form a single type of metal material. At present, sorting is generally carried out through sorting screens and manual cooperation. The sorting method is complicated, the sorting efficiency is low, and the sorting cost is high. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, propos...
