Electronic component circuit board disassembly process
Electronic waste contains a large number of circuit boards, and many components on waste circuit boards contain various toxic and harmful substances and heavy metals. It is necessary to disassemble and separate these components before recycling waste circuit boards. On the other hand, some components dismantled from waste circuit boards are still valuable, and many companies recycle them.
At present, the circuit board disassembly machine is used for disassembly. The circuit board with electronic components will produce smoke and odor during the disassembly process. These smoke not only affect the health of the staff, but also cause serious pollution to the atmospheric environment. environmental requirements.
The purpose of this utility model is to overcome the problem that a large amount of smoke and dust and pungent odors are generated when the current circuit board disassembly machine disassembles waste circuit boards, and provides a circuit board disassembly device, the circuit board disassembly device passes plasma The purifier can effectively remove dust. The UV photolysis air purifier can irradiate the malodorous gas, effectively crack the malodorous gas, decompose the toxic and harmful substances in the malodorous gas, and achieve the deodorization effect. The decomposed malodorous gas can achieve harmless discharge. , and never produce secondary pollution.
The utility model is realized as follows: a circuit board disassembly device, including a disassembly mechanism, an induced draft fan, a dryer, a plasma purifier and a UV photolysis air purifier, and the disassembly mechanism includes a rotating shaft and is installed on the rotating shaft. The drum is equipped with heating components, the drum wall is evenly provided with leakage holes, and the top of the drum is provided with a smoke dust hood, which is connected to the induced draft fan through a pipeline, and the induced draft fan is connected to the dryer through a pipeline. , the dryer is communicated with the plasma purifier, and the plasma purifier is communicated with the UV photolysis air purifier.
A circuit board disassembly device includes a disassembly mechanism:
1, the induced draft fan,
2. Dryer,
3. Plasma purifier,
4. UV photolysis air purifier,
5. The dismantling mechanism includes a rotating shaft and a drum mounted on the rotating shaft. The drum rotates with the rotating shaft. A heating element is arranged in the drum. The heating element is heated by liquefied gas, the heating element is a heating nozzle, and the rotating shaft is a hollow structure. The heating nozzle is arranged in the rotating shaft. The heating nozzle sprays fire to control the temperature inside the drum to about 150 °C. The tin on the circuit board is loosened by the high temperature. Gradually fall off from the circuit board; leak holes are evenly arranged on the wall of the drum, the electronic components that fall off are small in size, and are thrown out from the leak holes of the drum, and a recycling box is arranged under the drum.
6. It is used to collect electronic components; the circuit board with electronic components will generate soot and gas during the process of heating and dismantling, so a flue gas dust removal hood is set above the drum. There is a flue gas channel between the dust hood and the drum. The flue gas dust hood can block the smoke and gas inside the hood and prevent it from spreading outward. Under the action, the soot and gas in the flue gas channel are sucked out by the induced draft fan, the induced draft fan is connected with the dryer through the pipeline, the soot and gas enter the dryer for drying, the dryer is connected with the plasma purifier, and then the soot gas enters the ion purifier, Then the smoke and dust are purified, the plasma purifier is connected with the UV photolysis air purifier 5, and the odorous gas is photolyzed by UV to process the odor, and the new circuit board dismantling device can effectively remove dust and odor. , to meet the requirements of environmental protection.
