Refrigerators Recycling Plant for disassembly and recycling refrigerators.
1. Technical Introduction
Refrigerators Recycling Plant is a set of e-scrap recycling equipment which is used to disassemble refrigerant-contained home appliances such as refrigerator and air-con. It is consist of pre-processing work station, CFC pumping work position, first body shedding, second shedding and disassembly, sorted materials recycling devices. Based on technique of foreign companies, we first developed integrative technique of secondary shedding and bow wave shedding with characteristics of high automation, high efficiency, low function cost and zero secondary pollution. It has filled the blank of China’s refrigerator processing equipment and reached advanced international standards.
2. Process flow and Directions
The first is to manually disassemble refrigerator cabinet and resulting plastic, wire, glass, circuit board. The second is to reclaim refrigerant to ensure it would not pollute atmosphere. The third is to dismantle compressor and condenser. The fourth is to multi-level shred refrigerator body in shredder. In the shredder polyurethane is sucked out by air pump. The fifth is to separate iron by permanent magnet. In the last step aluminum and copper are separated by eddy current. The entire processing Equipment is located in an enclosed workshop. Exhaust gas and dust can be discharged by high pressure positive blower after being processed by activated carbon adsorption and hop-pocket dust extraction.
