Electronic waste contains a large number of circuit boards, and many components on used circuit boards contain various toxic and hazardous substances and heavy metals, and it is necessary to disassemble and separate these components before recycling the used circuit boards. On the other hand, waste circuit boards disassembled under the part of the components also have value, many companies to recycle. Circuit board recycling equipment using circuit board disassembly machine for disassembly, with electronic components of the circuit board in the disassembly process will produce smoke and odor, these fumes not only affect the health of the staff, and serious pollution of the atmosphere, does not meet the requirements of environmental protection.
The purpose of the utility model is to overcome the current circuit board disassembly machine in the disassembly of used circuit boards, generating a lot of smoke and dust and pungent odor, and provide a circuit board disassembly device, the circuit board disassembly device through the plasma purification machine can effectively remove dust, through the UV photolysis air purifier can irradiate malodorous gas, effective cracking malodorous gas, can decompose toxic and harmful substances in malodorous gas, to achieve Deodorization effect, after the decomposition of malodor gas, can achieve harmless emissions, never produce secondary pollution.
The utility model is realized in this way: a circuit board disassembly device, including disassembly mechanism, fan, dryer, plasma purifier and UV photolysis air purifier, the disassembly mechanism includes a rotating shaft and a drum mounted on the rotating shaft, the drum is set with a heating component, the drum wall is evenly set with holes, the drum is set with a fume dust hood above, the fume dust hood is connected to the fan through the pipe, the fan is connected to the dryer through the pipe. The fan is connected to the dryer through a pipe, the dryer is connected to the plasma purifier, and the plasma purifier is connected to the UV photolysis air purifier. A circuit board disassembly device includes disassembly mechanism.
1, the induced draft fan, the
3, plasma purification machine.
4, UV photolysis air purifier.
5, the disassembly mechanism includes a rotating shaft and the drum mounted on the rotating shaft, the drum rotates with the rotating shaft, the drum is set up with a heating component, heating component using liquefied gas heating, heating component for the heating nozzle, the rotating shaft for the hollow structure, heating nozzle set in the rotating shaft, heating nozzle spray fire can be controlled at a temperature of about 150 ℃ inside the drum, through the high temperature to loosen the tin on the circuit board, with the rotation of the drum, the circuit board and the cylinder wall collision friction, electronic components gradually from the With the rotation of the drum, the circuit board and the cylinder wall collision friction, electronic components gradually fall off from the circuit board; the drum cylinder wall is uniformly set with holes, the electronic components fall off the small size, from the roller of the hole in the dump, the drum is set below the recycling box.
6, for the collection of electronic components; circuit board with electronic components in the process of heating and dismantling, will produce smoke and gas, so there is a fume dust hood above the drum, the fume dust hood is an arc structure, fume dust hood and the drum is set up between the fume channel, fume dust hood can block the fume and gas in the inside of the hood, prevent it from spreading outward, fume dust hood through the duct and the induced draft fan connected, in the induced draft fan action, the fume dust hood can be used for the collection of electronic components. The fume dust hood is connected to the induced draft fan through the duct, and the fume dust and gas in the fume channel are sucked out by the induced draft fan, and the induced draft fan is connected to the dryer through the duct, and the fume dust and gas enter the dryer for drying, and the dryer is connected to the plasma purifier, and then the fume dust and gas enter the ion purifier, and then the fume dust is purified, and the plasma purifier is connected to the UV photolysis air purifier5, and the odorous gas is treated by UV photolysis. Through this new circuit board disassembly device, the dust and odor can be effectively removed to meet the requirements of environmental protection.
