Circuit board smashing recycling device

Abstract

The invention discloses a circuit board smashing recycling device. According to the circuit board smashing recycling device, by means of the arrangements of a screening bin, a rotating body and a magnetic body inside the rotating body, nonmetal scraps not subject to magnetic adsorption and metal scraps subject to the magnetic adsorption are screened into two different screening passages utilizingmagnetic force generated by the magnetic body, so that separation of metal and nonmetal is realized after circuit boards are smashed; the circuit board smashing recycling device is simple in structure, low in cost and convenient to use; and by means of the arrangements of a position-limiting groove, a cover plate, a pressure moving switch, a first convex block and a second convex block, when the position-limiting groove moves to the bottom of the rotating body, the position-limiting groove is covered and closed, by means of screening holes in the cover plate, the metal scraps of small sizes are made to fall, the metal scraps of large sizes continue to move with the position-limiting groove and are transported into a smashing mechanism through a conveyor belt to be smashed again, and the fact that the circuit boards can be completely smashed is guaranteed.

Description

technical field [0001] The invention relates to the technical field of circuit board recycling, in particular to a circuit board crushing and recycling device. Background technique [0002] With the development of my country's electronics industry, the elimination of waste electronic products and household appliances is increasing. At the same time, a large number of waste circuit boards are produced. If these waste circuit boards are directly discarded, it will cause great harm to the environment. On the other hand, there are often a lot of metals in the circuit board, such as gold, copper, lead, etc. If the metal can be recycled and reused, it will undoubtedly have a high market value. [0003] At present, the main method for crushing and recycling circuit boards on the market is to firstly crush the circuit boards in multiple stages through a crusher, and then use a roll-type corona-static composite electric field high-voltage electric separator to carry out metal separati...

Problems solved by technology

[0003] At present, the main method for crushing and recycling circuit boards on the market is to firstly crush the circuit boards in multiple stages through a crusher, and then use a roll-type corona-static composite electric field high-voltage electric separator to carry out metal separation on the crushed circuit boards. Non-metallic sorting, but this method has high requirements for equipment. The complete crushing of the circuit board must be ensured in the crushing stage to ensure the effect of sorting. The implementation cost is high. Other methods inject liquid nitrogen to freeze and crush and Methods such as pyrometallurgy are also difficult to promote in the market due to cost issues
