Waste household appliance treatment technological process

Abstract

The invention discloses a waste household appliance treatment technological process. The waste household appliance treatment technological process comprises the steps of: (S1) manual disassembly; (S2) crushing: massive materials are crushed to small-size materials; (S3) hydraulic sorting: light objects and heavy objects are separated in wastes; (S4) magnetic sorting: iron metal is separated from the wastes; (S5) eddy current sorting: plastic products in the wastes are recovered; and (S6) specific gravity sorting: copper and aluminum metals in the wastes are recovered. The waste household appliance treatment technological process is mainly for treatment of waste household appliances, adopts multi-station integral automatic treatment technology, is simple in technological process, adopts man-machine collaboration to achieve high treatment efficiency of the waste household appliances, is complete in resource recovery, is high in effective recovery rate of metals and plastics, is low in resource waste, can effectively solve the environmental pollution problem caused by the waste household appliances, and is high in practicability and wide in application range.

Description

technical field [0001] The invention relates to the technical field of waste product treatment technology, in particular to a process flow for the treatment of waste household appliances. Background technique [0002] With the progress of society and the development of high technology, the penetration rate and replacement rate of household appliances are increasing year by year. The volume of waste household appliances is generally large, it is troublesome to deal with, and the output is increasing year by year. At present, there is no effective treatment method, so waste household appliances have become a new source of urban pollution. Some household appliances contain substances harmful to the human body. If waste household appliances are not properly disposed of, they will not only pollute the environment, but also endanger human health. In fact, old household appliances have high economic value. For example, the proportion of copper, iron, and aluminum in TV sets is 16%...
