[0001] The invention relates to the field of copper deposition wastewater treatment, and more specifically to a copper deposition wastewater treatment system for integrated circuit boards for communications. Background Art
[0002] Integrated circuit boards are very important electronic components in electronic devices. In the production process of integrated circuit boards for communications, copper plating is required on the sides and through-holes of the circuit board through a copper plating process.
[0003] After the copper precipitation process is completed, there is still a certain amount of copper ions in the copper precipitation wastewater. These copper ions can form valuable copper elements after treatment in the copper precipitation wastewater.
[0004] The common copper precipitation wastewater treatment on the market usually adopts the method of adding sodium sulfite for neutralization. This treatment method will form flocculent copper precipitate. However, the copper content in copper precipitation wastewater is not fixed, and the flocculent copper precipitate also makes it impossible for staff to intuitively judge whether the copper element in the copper precipitation wastewater has formed copper element. This makes it impossible to accurately calculate the amount of sodium sulfite added, which easily causes the waste of sodium sulfite or copper precipitation wastewater.

The transfer device 6 includes a rotating rod 601, the outer end of which is fixedly connected to a columnar rod 602, and the outer end of the columnar rod 602 is provided with four slots 603 at equal angles, so that the filter device 7 is not easily offset during the rotation process.
[0026] See also Figure 7-11The filter device 7 includes a frame 701, a filter screen 702 is installed in the middle of the frame 701, four parts on one side of the frame 701 are fixedly connected with rectangular iron alloy sheets 703, a convex strip 704 is fixedly connected to the upper end of the frame 701, and strip iron alloy sheets 705 are fixedly connected to the left and right ends of the side of the frame 701 away from the rectangular iron alloy sheet 703, so that the flocculent copper precipitation can be blocked and adsorbed, which is convenient for the staff to collect the copper element later. The placement groove 403 matches the filter device 7, and the thickness of the guide groove 404 is the same as that of the filter device 7, and the linear module 413 can drive the filter device 7 to move. When the filter device 7 rotates along the transfer device 6, it can enter the placement groove 403, and the filter device 7 can pass through the guide groove 404 under the action of the linear module 413.
[0027] See also Figure 7-12 The pumping module 410 and the linear module 413 are electrically connected, and the one-way valve 411 can prevent the liquid from entering the L-shaped waterway 402 from the upper end, so that the linear module 413 can send an electrical signal to control the pumping module 410 to close, and the filter device 7 is not easily obstructed when it moves upward at the rear end of the L-shaped waterway 402. The inner wall of the Z-shaped block 401 is fixedly connected with a rubidium magnet at the upper side of the placement groove 403, and the filter device 7 can move in the middle of the L-shaped waterway 402, so that the filter device 7 can enter the middle of the placement groove 403 through the adsorption effect of the rubidium magnet when rotating along the transfer device 6, and the movement of the filter device 7 is not easily obstructed. The convex strip 704 matches the slot 603, and the rectangular ferroalloy sheet 703 corresponds to the permanent magnet 412, and the support plate 10 is located at the lower side of the filter device 7 at the lowermost side inside the storage slot 406, so that the T-convex strip 704 can enter the slot 603 for limitation, and the permanent magnet 412 can limit the filter device 7 through the rectangular ferroalloy sheet 703.
[0028] See also Figure 5-8 The storage box 501 contains a sodium sulfite solution, and the storage box 501, the transfer bin 504, the rectangular cavity 506 and the spray module 507 are connected to each other, and the rubber plug 510 can block the rectangular cavity 506, so that the copper precipitation wastewater can be replaced by the sodium sulfite reaction to produce copper, and the rubber plug 510 can control the sodium sulfite solution from flowing into the water reservoir 1. The lower half of the push plate 509 is located at the rear side of the frame 409, and the cross-sectional area of the pressing plate 503 is the same as the cross-sectional area of the storage box 501, so that when the water flows out of the rear end of the frame 409, the push plate 509 can be pushed to move, and the pressing plate 503 can squeeze out the sodium sulfite solution in the storage box 501.
[0029] When treating copper precipitation wastewater, the staff first pours the copper precipitation wastewater into the water reservoir 1, adjusts the size of the water outlet of the liquid spray module 507, opens the linear module 413 and the pumping module 410, and under the action of the tension spring 9 and the support plate 10, the four rectangular iron alloy sheets 703 at the front end of the filter device 7 at the uppermost side of the storage tank 406 are magnetically fixed by four permanent magnets 412, and the convex strip 704 at the upper end of the filter device 7 is inserted into the downward card slot 603; The pumping module 410 allows the copper precipitation wastewater in the water reservoir 1 to pass through the filter screen 702 in the middle of the flat filter device 7 through the L-shaped water channel 402. Since the flocculent copper element has not yet attached to the surface of the filter screen 702 at this time, the water flowing through the pumping module 410 passes through the frame 409 and pushes the push plate 509 to move backward. The push plate 509 drives the rubber plug 510 to move backward through the cross plate 508. At this time, the rubber plug 510 no longer blocks the sodium sulfite solution inside the transfer bin 504 from entering the liquid spraying module 507. The liquid spraying module 507 slowly releases the sodium sulfite solution into the surrounding copper precipitation wastewater environment, and diffuses the sodium sulfite solution into the entire water reservoir 1 through the copper precipitation wastewater flowing out from the rear end of the frame 409; The copper precipitation wastewater in the reservoir 1 reacts with sodium sulfite to generate flocculent copper precipitation, which flows to the periphery of the screening structure through the oblique slope 2 and the guide slope 3. At this time, under the action of the pumping module 410, the flocculent copper precipitation passes through the filter screen 702 in the middle of the filter device 7 and adheres to the surface of the filter screen 702. As more and more flocculent copper precipitation adheres to the surface of the filter screen 702, the filter screen 702 is gradually blocked. At this time, the copper precipitation wastewater can no longer pass through the filter screen 702. Under the suction action of the pumping module 410, a negative pressure is formed inside the L-shaped waterway 402. Under the action of the water pressure, the uppermost filter device 7 overcomes the magnetic force of the permanent magnet 412 and rotates along the rotating rod 601. Under the action of the water flow and the neodymium magnet on the strip iron alloy sheet 705, the filter device 7 moves along the rotating rod 601 to the placement groove 403. At this time, the linear module 413 receives a signal to control the filter device 7 to pass through the guide groove 404 and enter the rear end position of the L-shaped waterway 402. While the previous filter device 7 rotates along the rotating rod 601, the tension spring 9 drives another filter device 7 located at the lower side of the previous filter device 7 to move upward through the supporting plate 10, and the upper convex strip 704 of the filter device 7 is inserted into the slot 603 which is just located at the front end and is now rotated to the lower end, and the filter device 7 is magnetically limited by four permanent magnets 412. At this time, the L-shaped waterway 402 starts to pass through the copper precipitation wastewater again, and the flocculent copper precipitate gradually adheres to the surface of the filter screen 702 of the filter device 7. At the same time, under the water pressure of the copper precipitation wastewater, the filter device 7 just located at the rear end of the L-shaped waterway 402 moves upward. Because the movement of the filter device 7 is not restricted under the action of the one-way valve 411, the above process is repeated many times, so that the sodium sulfite solution is slowly and continuously released, and the flocculent copper precipitate is adsorbed by the filter screen 702, and multiple filter devices 7 that adsorb sufficient flocculent copper precipitate are stacked on the upper rear end of the L-shaped waterway 402. When the copper elements in the copper precipitation wastewater in the water reservoir 1 are basically collected, the flocculent copper precipitation in the water reservoir 1 is not enough to completely block the filter screen 702 of the filter device 7 located in the middle of the front end of the L-shaped waterway 402. The filter device 7 cannot overcome the magnetic limit of the permanent magnet 412. When the linear module 413 no longer senses the new filter device 7 entering the placement slot 403 within a certain period of time, the linear module 413 sends an electrical signal to control the pumping module 410 to close, and the pumping module 410 no longer performs pumping work. At this time, there is no water flowing out of the rear end of the frame 409. Under the action of the second compression spring 511, the rubber plug 510 moves forward so that the sodium sulfite solution in the transfer bin 504 no longer enters the spray module 507. At this time, the sodium sulfite solution stops being released. Finally, the staff takes out the multiple filter devices 7 stacked on the rear end of the L-shaped waterway 402, and scrapes off the copper element attached to the surface of the filter screen 702 for collection. The amount of sodium sulfite sprayed out by the spray module 507 can be controlled by the electrical connection between the linear module 413 and the pumping module 410, thereby avoiding the waste of sodium sulfite or copper elements, and the filtering device 7 reduces the workload of subsequent collection of flocculent copper precipitation.
[0030] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
