Problems solved by technology

[0005] At present, the common charging device is integrated with the feeding device, and mainly charges the particles of the electronic waste mixture through vibration and other methods during feeding. This method cannot control the charge of the electronic waste particles to a certain extent. Electricity, it is not convenient to measure the size of the electric charge
The common tribostatic separation device needs a bracket, which increases the cost to a certain extent

Abstract

The invention discloses an electronic waste friction electrostatic sorting device which comprises a charging device, a feeding device, a sorting device and a collecting device. The charging device comprises an air blower and a plastic friction barrel and is used for charging the electronic waste, so that the electronic waste particles carry charges with different polarities and then enter the feeding device. The feeding device comprises a support, a speed baffle and a feeding funnel. The sorting device comprises an acrylic protective cover and a polar plate. The collecting device comprises a collecting bin and a partition plate. Metal and non-metal substances in the electronic waste can be sorted out. The friction electrostatic sorting device is reasonably arranged, the charging device, the feeding device, the sorting device and the collecting device are designed, all the devices are matched with one another, and efficient sorting of the electronic waste can be achieved.

Description

technical field [0001] The invention relates to a processing device for electronic waste, in particular to a frictional electrostatic separation device for electronic waste. Background technique [0002] The development of human science and technology and the increasing demand of human economy and society have led to a sharp increase in the amount of electronic waste worldwide, and the amount is huge. [0003] In view of the special resources and hazards of electronic waste. E-waste is rich in aluminum, barium, chromium, copper, gallium, iron, lead, and phosphorus, as well as precious metal elements such as gold, silver, platinum, and rare earth elements such as samarium, europium, and yttrium. In addition, electronic waste also contains engineering plastics and glass fibers, and these two types of non-metals can also bring certain benefits through recycling. The harmful substances in electronic waste will cause great harm to the human body, animals, plants and ecology. T...
