Waste and old electric appliance reclaiming handling system and method

Abstract

The invention discloses a waste electrical appliances recovery and treatment system, comprising a negative-pressure operation chamber (1), an air purification system and a sorting machine (13). The operation chamber (1) is provided with at least an operation table and at least a crusher (2), both ends of the operation table are respectively connected with an electric appliance pretreatment production line outside the operation chamber (1) and the crusher (2) inside the operation chamber, the crusher (2) is connected with the sorting machine (13) outside the operation chamber (1), thus forming a continuous running production line for detaching electric appliances. The air purification system is provided with two collecting ports, one of which is communicated with the operation chamber (1), and the other is communicated with discharge outlets of a cutting machine (12) and the crusher (2), and the whole operation chamber (1) forms a close space. The invention also discloses a recovery treatment method of waste electric appliances for the waste electrical appliances recovery and treatment system. The invention can reduce the cost of manufacturing, running and maintenance of equipment.

Description

technical field [0001] The invention relates to a recycling and processing system and method for waste electric appliances, in particular to a recycling and processing system and method for waste and old electric appliances containing harmful gases. Background technique [0002] With the massive replacement of electrical products, the disposal of waste electrical appliances has become an important issue in urban construction at home and abroad. Due to the volatilization of the foaming agent and the generation of a large amount of dust during the dismantling and crushing of waste electrical appliances, it not only pollutes the environment but also endangers the health of operators. Therefore, waste electrical appliances recycling systems and large-scale processing plants have been established in foreign countries, especially economically developed countries, to recycle waste electrical appliances. [0003] At present, foreign countries have developed a fully enclosed and ful...

AI Technical Summary

Problems solved by technology

The process is fully enclosed and fully automated, with high recycling efficiency and no secondary pollution. However, since the whole machine is crushed, the requirements for cutting tools and crushing technology are very high, so the cost of the entire set of recycling equipment is quite expensive, and Very expensive to maintain and operate

[0004] However, the current situation of recycling waste electrical appliances in my country is extremely backward in its collection and processing. The recycling method adopted is still purely manual dismantling. There is no standardized process flow and the environmental protection requirements of the processing process are not fully considered, resulting in waste of resources and environmental pollution. , but if the above-mentioned foreign methods are used, although the recovery efficiency is high and there is no secondary pollution, the recycling equipment used is expensive, and the maintenance and operation costs are high, which is not completely suitable for the current situation of my country's abundant labor resources and relatively weak economic foundation.
