Process of the application to waste refrigerator harmless treatment and resource high-efficiency recycling are as follows:

1, refrigerator is disassembled: in production line front end disassembling stations, manually being disassembled to waste refrigerator, removing from cabinet can be single Plastic part, electrical appliance kit, electric wire, glass, the wiring board solely dismantled；

2, in recycling refrigerant: fluorine station is taken out in production line middle section, using refrigerant negative pressure extracting recyclable device in compressor Refrigerant recycled；

3, in production line back end disassembling stations, manual removal should not use compressor, the condenser of broken crusher machine；

4, remaining cabinet and door crushing system is sent directly by feeding device to be crushed；Make metal, plastics and Foam is thoroughly dissociated, in order to the classification of comminuting matter later separation.

5, above-mentioned broken material is subjected to pneumatic separating, the lesser polyurethane foam of cyclone collector collection cut size, Tail gas qualified discharge after deduster dedusting；

6, above-mentioned rest materials are fallen into belt conveyor, removes iron by way of permanent magnetism self-tipping type in its automatic transmission process Device separates bulk ferrous metal iron；

7, material is finally sent through belt conveyor to vibra feeder, vibra feeder material uniformly continuous is sent again to Cartridge type iron remover carries out magnetic separation, and the remaining small bits of iron that do not isolate is totally separated out, and through cartridge type iron remover material Bucket falls into splicing vehicle；

8, through cartridge type iron remover, another hopper falls into vibra feeder to last remaining material, and vibra feeder is again by object It send to eddy current separator to material uniformly continuous, valuable non-ferrous metal copper, aluminium and plastics and thick polyurethane foam is separated, And different splicing vehicles is respectively fallen in, realize 98% or more resource reclaim regeneration.

Wherein two coarse crushing axis 10-2 in two axis crushers 10 are rotated towards each other, and have been carried out by quartering hammer strike rough and torn It is broken, type fine disintegrating machine 11 is entered back into later and carries out secondary fine crushing, is equipped with crushing cutter in type fine disintegrating machine 11, crushing cutter 11-3 is carried out It is crushed again.Crushing device compared with the existing technology has been changed in the application and has been crushed twice, can be improved crushing efficiency, and It is crushed more uniform.
