Production line for harmless treatment and efficient resource recovery for waste refrigerators

Abstract

The invention provides a production line for harmless treatment and efficient resource recovery for waste refrigerators. According to the production line, a first crushing device is connected to a second crushing device through a conveying device; the conveying device between the first crushing device and the second crushing device is provided with an iron removal device; the second crushing device is connected to a distributor; a discharge port at the bottom of the distributor is connected to a metal sorting device; and at least one foam suction device is further arranged between the first crushing device and the metal sorting device and is connected to a foam compressor. The production line has the advantages that the efficiency of the harmless treatment and efficient resource recovery for the waste refrigerators can be improved through reasonable equipment selection and arrangement, the crushing efficiency can be improved, the crushing frequency of polyurethane foam can be reduced, and the risk of fire combustion of polyurethane foam can be reduced.

Description

technical field [0001] The invention relates to the field of waste refrigerator treatment, in particular to a production line for harmless treatment of waste refrigerators and efficient resource recovery. Background technique [0002] With the development of science and technology, the replacement of refrigerators is getting faster and faster, and the amount of waste refrigerators to be disposed of is increasing. The development of dismantling of waste refrigerators can not only reduce environmental pollution and energy waste, but also provide social benefits. Rich renewable resources, traditional equipment has low production capacity, low recovery rate, high energy consumption, and potential safety hazards. [0003] Chinese patent document CN 101670355 B discloses a method and equipment for harmless treatment of waste refrigerators and efficient recycling of resources. In the dismantling station, plastics, electrical appliances, compressors, condensers and other components ...

AI Technical Summary

Problems solved by technology

The problem is that the crushing efficiency is not good, and the sorting is carried out after repeated crushing. During this process, the polyurethane foam is repeatedly crushed, which increases the difficulty of crushing, and the polyurethane foam that has been crushed and squeezed for many times also increases. fire risk

Recycled non-ferrous metals include aluminum, copper, and some stainless steels. It is difficult to reliably separate them with only one eddy current sorter, and manual sorting is required in the later stage, which increases the work intensity.
