Embodiment Construction

[0034] The present invention is described below according to accompanying drawing.

[0035] figure 1 It is a schematic diagram of the overall structure of the equipment. The box shell is composed of two layers of non-magnetic metal plates with thermal insulation material glass fiber cotton in the middle. The box is connected and optionally swivel, and the lower end can be closed under the action of gravity. One side of the upper end of the box body is an air inlet 103, and the blower is on the outside of the box body, and is connected to the air inlet 103 on the top of the shell through a pipe. For heating, the heating temperature of the heating electric wire mesh is adjustable, and the adjustment range is 150°C to 300°C. An impact mechanism 105 is arranged in the middle part of the upper end of the box body, and the impact mechanism is driven by other external power mechanisms. The door on the other side of the box can be opened and closed, which is convenient for the asse...

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...
