Membrane electrolysis needs to be carried out in an electroplating solution, and after a long period of use, the electroplating solution inevitably contains some impurities. In order to ensure the normal progress of subsequent processing, the electroplating solution needs to be purified regularly.

[0003] However, the purification devices currently used for membrane electroplating solutions still have some defects in use. The filter structure cannot be easily cleaned during purification, which leads to the accumulation of impurities and affects the subsequent purification effect.

[0004] A new type of membrane electroplating solution purification device is now being developed to address the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a membrane electroplating solution purification device to solve the problem mentioned in the background art of the inconvenience of cleaning the filter structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a membrane electroplating solution purification device, comprising a purification tank, wherein two ends of the bottom sides of the purification tank are fixedly connected to support legs, and a water inlet is fixedly connected to the top of the purification tank, the water inlet being connected to the interior of the purification tank, and the interior of the purification tank being provided with a filter structure for convenient cleaning of impurities.

[0007] The filter structure includes a positioning ring, which is movably connected inside the water inlet. A support frame is fixedly connected to the bottom end of the positioning ring, and a filter screen is fixedly connected inside the support frame. A rubber ring is fixedly connected to the bottom end of the positioning ring, and an external threaded frame is movably connected to the top end inside the water inlet. Vertical plates are fixedly connected to both sides of the top two ends of the positioning ring, and a support ring is fixedly connected to the bottom end inside the water inlet.

[0008] As a further technical solution of this utility model, the external threaded frame is movably connected to the upright plate, and the rubber ring is movably connected to the support ring.

[0009] As a further technical solution of this utility model, the center line of the external threaded frame and the center line of the water inlet are on the same vertical plane, and the center line of the support ring and the center line of the water inlet are on the same vertical plane.

[0010] As a further technical solution of this utility model, a fixing frame is fixedly connected to the top of the external threaded frame, a drive motor is fixedly connected to the top of the fixing frame, a rotating shaft is fixedly connected to the output end of the drive motor through the fixing frame, connecting rods are fixedly connected to both sides of the rotating shaft, and a brush plate is fixedly connected to one side of the connecting rod.

[0011] As a further technical solution of this utility model, the brush plate is movably connected to the filter screen, and the center line of the rotating shaft and the center line of the support frame are on the same vertical plane.

[0012] As a further technical solution of this utility model, a fixing plate is fixedly connected to the bottom left side of the purification box, a water pump is fixedly connected to the top of the fixing plate, a return pipe is fixedly connected to the output end of the water pump, a water pumping pipe is fixedly connected to the input end of the water pump, a water outlet valve is fixedly connected to the bottom right side of the purification box, and a support sleeve is fixedly connected to the left side of the top of the purification box.

[0013] As a further technical solution of this utility model, the return pipe passes through the left side of the water inlet and is connected to the inside of the water inlet, and the return pipe is fixedly connected to the support sleeve.

[0014] As a further technical solution of this utility model, the water pumping pipe passes through the left side of the purification box and extends into the interior of the purification box, and the water outlet valve is connected to the interior of the purification box.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the membrane electroplating solution purification device not only enables convenient cleaning of the filter structure and improves purification efficiency, but also enables multiple filtrations to improve the purification effect.

[0016] The system includes an inlet, an external threaded frame, a vertical plate, a filter screen, a support frame, a positioning ring, a rubber ring, and a support ring. After a period of purification, the external threaded frame can be rotated to remove it from inside the inlet. Then, the positioning ring can be pulled to remove the support frame and the internal filter screen from inside the purification box for cleaning. After cleaning, the support frame is inserted into the purification box, with the rubber ring at the bottom of the positioning ring fitting against the top of the support ring. The external threaded frame is then rotated into the inlet to be positioned by the threads inside the inlet.

[0017] By incorporating an external threaded frame, a fixed bracket, a drive motor, a rotating shaft, a connecting rod, and a brush plate, the electroplating solution is introduced through the inlet and passes through the filter screen during the purification process. The filter screen automatically filters out impurities. Simultaneously, the drive motor at the top of the fixed bracket is activated to rotate the rotating shaft. As the shaft rotates, the connecting rod causes the brush plate to rotate inside the filter screen, continuously scraping off impurities adhering to the inner wall of the filter screen. This prevents water pressure from causing impurities to adhere to the inside of the filter screen, resulting in blockage and reduced purification efficiency, thus improving purification efficiency.

[0018] The system is equipped with an inlet, support sleeve, return pipe, water pump, fixing plate, suction pipe, and outlet valve. After the electroplating solution completes one filtration inside the filter screen, the water pump at the top of the fixing plate is activated. The water pump draws the filtered electroplating solution out of the purification tank through the suction pipe and then guides it back into the inlet through the return pipe. It then passes through the filter screen again for filtration. Multiple filtrations can improve the purification effect. After purification is complete, the outlet valve can be opened to discharge the electroplating solution, thus achieving multiple filtrations to improve the purification effect.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figure 1-4 A membrane electroplating solution purification device includes a purification tank 1. Support legs 15 are fixedly connected to both ends of the bottom sides of the purification tank 1. A water inlet 2 is fixedly connected to the top of the purification tank 1. The water inlet 2 is connected to the interior of the purification tank 1. The interior of the purification tank 1 is provided with a filter structure for easy cleaning of impurities.

[0026] The filter structure includes a positioning ring 19, a positioning ring 19 is movably connected inside the inlet 2, a support frame 18 is fixedly connected to the bottom end of the positioning ring 19, a filter screen 11 is fixedly connected inside the support frame 18, a rubber ring 20 is fixedly connected to the bottom end of the positioning ring 19, an external threaded frame 3 is movably connected to the top end inside the inlet 2, upright plates 6 are fixedly connected to both sides of the top two ends of the positioning ring 19, and a support ring 21 is fixedly connected to the bottom end inside the inlet 2.

[0027] The external threaded frame 3 is movably connected to the upright plate 6, and the rubber ring 20 is movably connected to the support ring 21.

[0028] The centerline of the external threaded frame 3 and the centerline of the inlet 2 are on the same vertical plane, and the centerline of the support ring 21 and the centerline of the inlet 2 are on the same vertical plane;

[0029] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, after a period of purification, the external threaded frame 3 can be rotated to remove it from the inside of the inlet 2. Then, the positioning ring 19 can be pulled to remove the support frame 18 and the internal filter screen 11 from the inside of the purification box 1 to clean the impurities inside. After cleaning, the support frame 18 is inserted into the inside of the purification box 1. The rubber ring 20 at the bottom of the positioning ring 19 is attached to the top of the support ring 21. Then, the external threaded frame 3 is rotated into the inside of the inlet 2 and positioned by the threads inside the inlet 2. The external threaded frame 3 is attached to the top of the upright plate 6 and the support frame 18 is positioned by the upright plate 6, which makes it easy to disassemble and assemble the filter screen 11 for cleaning.

[0030] A fixed frame 4 is fixedly connected to the top of the external thread frame 3. A drive motor 5 is fixedly connected to the top of the fixed frame 4. A rotating shaft 9 is fixedly connected to the output end of the drive motor 5 through the fixed frame 4. Connecting rods 10 are fixedly connected to both sides of the rotating shaft 9. A brush plate 17 is fixedly connected to one side of the connecting rod 10.

[0031] The brush plate 17 is movably connected to the filter screen 11, and the center line of the rotating shaft 9 and the center line of the support frame 18 are on the same vertical plane.

[0032] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, during the purification process, the electroplating solution is introduced through the inlet 2 and passes through the filter screen 11. The filter screen 11 can automatically filter out impurities. At the same time, the drive motor 5 at the top of the fixed frame 4 can be activated to drive the rotating shaft 9 to rotate. As the rotating shaft 9 rotates, it drives the brush plate 17 to rotate inside the filter screen 11 through the connecting rod 10. This can continuously scrape off the impurities attached to the inner wall of the filter screen 11, preventing water pressure from causing all the impurities to adhere to the inside of the filter screen 11 and causing blockage, thus improving the purification efficiency.

[0033] A fixing plate 13 is fixedly connected to the bottom left side of the purification box 1. A water pump 12 is fixedly connected to the top of the fixing plate 13. A return pipe 8 is fixedly connected to the output end of the water pump 12. A water pumping pipe 14 is fixedly connected to the input end of the water pump 12. A water outlet valve 16 is fixedly connected to the bottom right side of the purification box 1. A support sleeve 7 is fixedly connected to the left side of the top of the purification box 1.

[0035] The water pipe 14 passes through the left side of the purification box 1 and extends into the interior of the purification box 1, and the water outlet valve 16 is connected to the interior of the purification box 1.

[0036] Specifically, such as Figure 1 As shown, after the electroplating solution completes one filtration inside the filter screen 11, the water pump 12 at the top of the fixed plate 13 is started. The water pump 12 draws out the electroplating solution filtered inside the purification tank 1 through the water suction pipe 14 and then introduces it into the water inlet 2 through the return pipe 8. It then passes through the filter screen 11 again for filtration. Multiple filtrations can improve the purification effect. After purification is completed, the water outlet valve 16 can be opened to discharge the electroplating solution, thus realizing multiple filtrations to improve the purification effect.

[0037] Working Principle: During the purification process, the electroplating solution is introduced through the inlet 2 and passes through the filter screen 11, which automatically filters out impurities. Simultaneously, the drive motor 5 at the top of the mounting bracket 4 drives the rotating shaft 9 to rotate. The rotating shaft 9, through the connecting rod 10, drives the brush plate 17 to rotate inside the filter screen 11, continuously scraping off impurities adhering to the inner wall of the filter screen 11. This prevents water pressure from causing impurities to adhere to the filter screen 11 and blockage, thus affecting purification efficiency. After the electroplating solution completes one filtration through the filter screen 11, the water pump 12 at the top of the mounting plate 13 is activated. The water pump 12 draws the filtered electroplating solution from inside the purification tank 1 through the suction pipe 14 and then introduces it back into the purification tank 1 through the return pipe 8. Inside the inlet 2, the solution is filtered again through the filter screen 11. Multiple filtrations improve the purification effect. After purification, the outlet valve 16 can be opened to discharge the electroplating solution. After a period of purification, the external threaded frame 3 can be rotated to remove it from inside the inlet 2. Then, the positioning ring 19 can be pulled to remove the support frame 18 and the internal filter screen 11 from inside the purification box 1 to clean the impurities inside. After cleaning, the support frame 18 is inserted into the purification box 1. The rubber ring 20 at the bottom of the positioning ring 19 is attached to the top of the support ring 21. Then, the external threaded frame 3 is rotated into the inlet 2 to cooperate with the threads inside the inlet 2 to position the external threaded frame 3. The external threaded frame 3 is attached to the top of the upright plate 6, and the upright plate 6 positions the support frame 18.
