Harmless disassembling and resource classified recycling equipment and method of waste refrigerator

Abstract

The invention relates to the technical field of environment protection aiming to recycling treatment of substances in a waste refrigerator. Manual pre-treatment is carried out on a disassembling station; the treated refrigerator is crushed and harmful gas is treated to obtain material grains; rough iron is sorted through suspension magnetic selection, and polyurethane foam is selected through wind selection; the rough iron and the polyurethane foam are subjected to dust removal and block pressing treatment; fine iron is selected through a rubidium-iron roller and a separator; copper and aluminum are selected through non-ferrous metal sorting and are treated into copper and aluminum grains with a hammer mill, and the copper and aluminum grains are subjected to dust removal treatment; the copper and the aluminum are sorted through proportion sorting; and ABS (Acrylonitrile Butadiene Styrene) and other plastic are sorted through light spectrum sorting. The invention provides harmless disassembling and resource classified recycling equipment and method of a waste refrigerator and a scientific, reasonable and standard recycling flow is established.

Description

Technical field [0001] The invention relates to the environmental protection technical field of recycling materials in used refrigerators, and specifically relates to a harmless dismantling and resource classification recovery system for used refrigerators. Background technique [0002] Since the beginning of the 21st century, science and technology have continued to advance, and the emergence of household appliances has improved people's living standards. With the continuous upgrading of electrical products, it has become a top priority to deal with waste electrical appliances and eliminate environmental hazards, which has caused social concern. of great concern. Among the increasing number of used household appliances, refrigerators account for a large proportion. A refrigerator is a cabinet or box that keeps food or other items cold and contains a compressor and an ice machine for freezing. It has become a daily life for people. Indispensable household appliances. Howev...

Problems solved by technology

[0006] In the prior art, the recycling and dismantling process of waste refrigerators is not detailed enough, the precious non-ferrous metals are not further separated after separation, and the plastics are not further distinguished and separated; at the same time, the polyurethane after winnowing is not further processed; this technology The medium crushing cuts the strip material first, and then secondary crushing, the efficiency is low, the crushed particles are large, the resource utilization efficiency is affected, and the resource utilization rate after sorting has not been effectively counted
