Automatic disassembly and recovery device for electronic components of waste printed circuit board

Abstract

The present invention discloses an automatic disassembly and recovery device for electronic components of a waste printed circuit board (PCB), and belongs to the technical field of resource utilization of the electronic waste. The device comprises four parts of a material feeding flap valve, a continuous gradual temperature rising chamber, a pulse vibration disassembly chamber and a material discharging and valve flapping tower, wherein the four parts are connected to form a sealed integrity. A preheating conveying belt and a reflux cooling tube are arranged in the continuous gradual temperature rising chamber, and a gas exhaust outlet and a trap valve are arranged in the continuous gradual temperature rising chamber. The pulse vibration disassembly chamber is provided with a high temperature mesh conveying belt, a high temperature separation pulse injection tube, a vibration separator and a vibration separation screen, and is connected with the trap valve. A material discharging flap valve is connected with the pulse vibration disassembly chamber. Compared to the prior art, with the present invention, the superheated steam is adopted as the heating source; the vibration separation of the waste PCB and the electronic components of the waste PCB is realized through pulse injection of the superheated steam; the whole sealed design is adopted to realize the harmless automatic disassembly and separation of the waste PCB and the electronic components of the waste PCB.

Description

technical field [0001] The invention discloses an automatic dismantling and recycling device for waste printed circuit board electronic components, which belongs to the technical field of resource utilization of electronic waste. Background technique [0002] Printed circuit boards are the foundation of the electronics industry and are widely used in electronic and electrical equipment such as computers, communication equipment, measurement and control instruments, and household appliances. Printed circuit boards are about 3% of the entire e-waste. At present, the average growth rate of printed circuit boards in the world is 8%-9%, while the growth rate in some Asian countries and regions is as high as 20%-30%. At present, the total size of my country's electronic product market has reached 1 trillion yuan, and the output value of the electronic industry has ranked fourth in the world. A lot of production will inevitably lead to a lot of waste. According to statistics, 80...
