The invention discloses a device and method for recovering waste circuit board components, which include a support base, a heating unit, a vibration unit, a feeding and discharging unit, and an exhaust gas treatment unit, wherein: the heating unit includes a heating box, which is arranged obliquely to heat Heating wires are arranged inside the box; the vibrating unit includes a vibrating screen cage, which is installed obliquely and placed above the heating box; the vibrating motor can drive the vibrating screen cage to reciprocate up and down; the feeding and discharging unit includes a feeding funnel, a unit Device chute and waste circuit board substrate chute; the exhaust gas treatment unit includes a dust collection hood, which is set on the heating box cover above the vibrating screen cage, and the dust collection hood is connected with a centrifugal fan, cyclone separator and exhaust gas treatment through pipelines in sequence box. The invention can carry out large-scale continuous treatment of discarded circuit boards, and at the same time carry out harmless treatment on the tail gas in the recovery process, and the whole process is safe, efficient and environment-friendly.
Description
technical field [0001] The invention belongs to the technical field of recycling electronic components, in particular to a recycling device and method for discarded circuit board components. Background technique [0002] With the continuous upgrading of electronic products such as computers, mobile phones and tablet computers, a large amount of electronic waste is generated in my country every year, among which discarded circuit boards account for a large proportion. In different electronic and electrical products, the proportion of circuit boards varies from 2-20%. It is estimated that the proportion of 5% is estimated to be about 2 million tons of waste circuit boards in the world every year, and 400,000 tons of waste circuit boards are produced in China every year. There are a large number of electronic components on these discarded circuit boards, some of which can be reused. For the damaged components, because they contain a large amount of valuable metals such as gold,...
