[0002] The names of circuit boards include: circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. However, a lot of wastewater will be generated during the production process of circuit boards. How to filter, collect and recycle the wastewater has become a problem that must be solved.

[0003] Publication number: CN 218146092 U's patent discloses a physical purification device for circuit board wastewater, which includes a treatment box, a feed pipe is fixedly connected to the top of the treatment box, a filter channel is opened at the upper end of the interior of the treatment box, and a filter frame No. 1 is slidably connected to one side of the treatment box corresponding to the filter channel. The device filters larger impurities in the wastewater through the No. 1 filter frame, and the filtered wastewater is filtered through the No. 2 filter frame for smaller impurities, and the impurities and odors in the wastewater are adsorbed through the No. 1 activated carbon filter plate and the No. 2 activated carbon filter plate to reduce the pungent odor and microbial impurities in the wastewater, improve the treatment of wastewater, and reduce the impact on the environment. However, the device has the problem of introducing wastewater from the feed pipe into the treatment box and filtering it by the No. 1 filter frame. Although the No. 1 filter can be removed from the treatment box to clean impurities by using the fixed shaft 4 and the rotating gear lever, the wastewater is continuously introduced for filtration, and the No. 1 filter frame also needs to be continuously disassembled, cleaned and installed, which is very troublesome. Therefore, an electronic circuit board production wastewater filtration device is proposed to solve the problem that the existing wastewater filtration device is difficult to quickly filter and collect impurities.
