Description

Technical Field

[0001] The utility model relates to the technical field of circuit board recycling, in particular to a circuit board crushing and recycling line. Background Art

[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts.

[0003] At present, most of the traditional circuit board recycling equipment can only achieve single crushing, and its crushing effect is limited. It is impossible to separate and recover the copper powder and resin in the circuit board, and the large amount of dust generated during the working process cannot be processed, which is easy to pollute the environment and bring unnecessary trouble. For this reason, we propose a circuit board crushing and recycling line to solve the problems raised in the above background technology. Utility Model Content

[0012] The utility model is used to process the bare board after the components are removed. First, it enters the double-shaft crusher through the first conveyor to be roughly crushed into materials of about 30mm, and then enters the plastic crusher through the second conveyor to be crushed into particles of about 3mm, and then enters the turbine grinder for grinding. The ground powder enters the specific gravity separator for sorting, most of the copper powder is selected by wind, and the rest of the powder enters the high-voltage electrostatic separator to separate a small amount of copper powder and resin inside. The dust generated in the middle of the whole recycling line will be removed by two pulse dust collectors.
