Equipment for dissembling waste and old circuit board

Abstract

A device for disassembling a waste circuit board comprises a shell, an electric heater and a fan, which is characterized in that an internal heating space of the device is equipped with a rotatable rotary barrel for placing the waste and old circuit board, and the barrel wall of the rotary barrel is provided with a mesh hole which can be passed by an element. The device can realize the purpose of the automatic disassembly of the waste and old circuit board. The device has the advantages that: compared with the manual disassembly and washing, the efficiency is greatly improved; as the temperature of hot wind of the internal heating space of the device is adjustable and controllable, the set temperature of the hot wind can not only melt a tin point, but also not cause the decomposition of the PCB board and the paint, thus greatly reducing the generation of waste gas; as the internal heating space of the device is near to the closed state when in work, the hot wind is recycled, which can not only save the energy, but can also further reduce the emission of the waste gas to the air.

[0002] The dismantling and recycling of the circuit boards of waste electrical appliances is an increasingly important environmental protection work.

Because the temperature of the coal furnace is difficult to control, too high temperature often causes the PCB board and the paint on it to decompose, producing a large amount of toxic waste gas, which is directly discharged into the air, causing serious air pollution, and the efficiency of manual operation is very low
