[0034] The use state of the present invention is as follows: when in use, the liquid inlet pump 8 works, and the etching waste liquid is drawn in through the liquid inlet pipe 9, and discharged into the box body 1 through the liquid discharge pipe 10. At this time, the electrode 11 works, and the waste liquid is subjected to electrolysis reaction, and the ions will be ionized out of the waste liquid. At the same time, the motor 12 works, and the rotating shaft 13 of the motor 12 drives the connecting sleeve 14 to rotate, and the connecting sleeve 14 drives the connecting rod 16 to rotate, and the connecting rod 16 drives the stirring blade 17 to rotate, which can have a stirring effect on the waste liquid in the box body 1, accelerate the electrolysis reaction of the waste liquid, and thus improve the working efficiency.

When the solution passes through the screen 22, the screen 22 will be driven to move downward, and the screen 22 will drive the mounting plate 21 to press down the first spring 25. The expansion and contraction of the first spring 25 will cause the screen 22 to vibrate, thereby preventing the copper from clogging the screen 22. The solution can be drawn out through the liquid inlet 28 by the drainage pump 26, and then discharged through the drainage port 27, thereby achieving the effect of recycling the waste liquid. When the electrolytic reaction produces exhaust gas, the exhaust gas will be discharged into the vent cylinder 33 through the air inlet 34. When the exhaust gas pressure is high, it will drive the piston 35 to move downward, so that the exhaust gas can be discharged into the filter box 31 through the air outlet 39. The filter screen 41 can filter the exhaust gas, so that the filtered exhaust gas will not cause pollution to the environment when it is discharged through the exhaust port 32. When the piston 35 moves downward, it will drive the guide rod 36 to move downward. The guide rod 36 will drive the limit ring 37 to move downward, so that the limit ring 37 will drive the filter screen 41 to move, so that the slide plate 40 drives the positioning rod 42 to press the third spring 45 downward. Through the expansion and contraction of the third spring 45, an upward reaction force will be given to the positioning rod 42, so that the positioning rod 42 will drive the slide plate 40 upward to move, thereby causing the filter screen 41 to vibrate, which can effectively prevent the filter screen 41 from being blocked and improve work efficiency.
