Method and system for separating electron components in waste circuit board in electromagnetic induction

Abstract

The invention discloses a method and system for separating electron components in a waste circuit board in electromagnetic induction. The system is characterized in that a heating electric wire with adjustable temperature, an air supply / air suction device, a transmitting device, an impact vibrating device, an electromagnetic absorption device, a component recycling net and a circuit board recycling baffle are arranged in a sealed box body with a feed port board; the waste circuit board is sent to a transmitting belt through the feed port, and slowly transmitted to a heating area, a part of electron components is separated under the high temperature and electromagnetic absorption effect, when the waste circuit board slowly passes through the impact vibrating device, the other electron components are separated under rapid impact effect; the electron components fall on the component recycling net to be recycled; a waste gas recycling processing device recycles and processes toxic and harmful gas released by the heated waste circuit board in the work process. The method and system in the invention is an efficient and harmless and has simple apparatus and high efficiency of separating the electron components, and is capable of processing the waste circuit board in batch in the earlier stage.

Description

Technical field: [0001] The invention relates to a method and system for electromagnetic induction separation of electronic components in waste circuit boards. The invention can realize the harmless and high-efficiency separation of waste printed circuit boards and electronic components, so as to facilitate the recycling of waste circuit boards. The utility model belongs to the field of environmental protection equipment and application technology. Background technique: [0002] With the rapid development of electronic industry technology and the continuous expansion of the demand market for electronic products, the number of electronic products has also increased rapidly, and the amount of electronic waste has also increased rapidly. A large number of waste electrical appliances have been abandoned to form electronic waste, which has gradually become An important part of municipal solid waste, its quantity increases by 16% to 28% every five years, three times faster than th...

AI Technical Summary

Problems solved by technology

[0006] 1. The efficiency of dismantling electronic components is low. Only a single waste circuit board can be separated from electronic components. The loading and unloading is cumbersome, and continuous batch processing cannot be realized.

[0007] 2. The treatment box cannot be completely sealed, which may easily cause the leakage of toxic gas and pollute the environment
