Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, specifically to an electroplating solution recycling device. Background Technology

[0002] Electroplating is a process that uses the principle of electrolysis to deposit a layer of another metal or alloy onto the surface of a metal or other material. Through electrolysis, metal cations on the surface of the metal or material are reduced in an electrolyte solution, thereby forming a metal film on the substrate surface. The main purposes of electroplating are to prevent metal oxidation, improve wear resistance, conductivity, reflectivity, corrosion resistance, and enhance aesthetics.

[0003] After electroplating, many impurities remain in the electroplating solution. If it needs to be recycled, it needs to be filtered. However, after a long period of use, the impurities in the electrolyte will clog the filter screen of the current filtration device, affecting the filtration effect. It is also necessary to lift the filter screen to clean it, which is very troublesome.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: it includes an outer shell 1, an outer filter frame 2 rotatably arranged inside the outer shell 1, a support tube frame 3 rotatably arranged on the side of the outer shell 1 and the outer filter frame 2 that are far apart from each other, an inner filter frame 5 rotatably arranged inside the outer filter frame 2, a water inlet frame 6 rotatably arranged inside the inner filter frame 5, and cleaning brushes 7 connected to the surfaces of the inner filter frame 5 and the water inlet frame 6, a slag discharge pipe 8 connected to the bottom end of the outer shell 1, a water inlet pipe 9 connected to one side of the inner wall of the outer shell 1, a plurality of nozzles 10 connected to the bottom end of the water inlet pipe 9, and an external water source connected to the other end of the water inlet pipe 9, a drive motor 11 connected to one end of the support tube frame 3, a transmission shaft 12 connected to the output end of the drive motor 11, the other end of the transmission shaft 12 passing through the support tube frame 3 and connected to the water inlet frame 6, and a circulation pipe 14 connected to one side of the outer shell 1;

[0023] One end of the support tube frame 3 is connected to a first side plate 31 and a second side plate 32. Multiple sets of round shafts are rotatably arranged on one side of the first side plate 31 and the second side plate 32. The two ends of the round shaft on the first side plate 31 are connected to an inner connecting gear 33, and the two ends of the round shaft on the second side plate 32 are connected to an outer connecting gear 34. A second inner toothed ring 61 is connected to one side of the water inlet frame 6. A second outer toothed ring 51 is connected to one side of the inner wall of the inner filter frame 5. A first inner toothed ring 52 is connected to one side of the inner filter frame 5, and a first outer toothed ring 21 is connected to one side of the inner wall of the outer filter frame 2.

[0024] Reference Figure 3 As shown, the first side plate 31 is located between the water inlet frame 6 and the inner filter frame 5, and the second side plate 32 is located between the inner filter frame 5 and the outer filter frame 2. The inner connecting gear 33 at one end of the round shaft on one side of the first side plate 31 meshes with the second inner gear ring 61, and the inner connecting gear 33 at the other end meshes with the second outer gear ring 51. The outer connecting gear 34 at one end of the round shaft on one side of the second side plate 32 meshes with the first inner gear ring 52, and the outer connecting gear 34 at the other end meshes with the first outer gear ring 21. Simultaneously, the drive motor 11 drives the water inlet frame 6 to rotate via the transmission shaft 12. The second internal gear ring 61 drives the inner connecting gear 33 to rotate. The other inner connecting gear 33, which is symmetrically connected by a round shaft, will also rotate, thereby driving the second external gear ring 51, which in turn drives the inner filter frame 5 to rotate. The rotation of the inner filter frame 5 will drive the first internal gear ring 52 to rotate. Then, through the same method, the outer connecting gear 34 drives the first outer gear ring 21, causing the outer filter frame 2 to rotate. Finally, the outer filter frame 2, the inner filter frame 5, and the water inlet frame 6 rotate simultaneously, so that the cleaning brush 7 cleans the inner sides of the outer filter frame 2 and the inner filter frame 5.

[0025] Reference Figure 2 As shown, one end of a set of support tube frames 3 passes through the outer shell 1 and extends into the water inlet frame 6, and another set of support tube frames 3 is rotatably connected to the outer filter frame 2 and the inner filter frame 5. The electrolyte to be filtered can be input into the device through the support tube frames 3.

[0026] Reference Figure 1 and Figure 2 As shown, each end of the support tube frame 3 that is far apart from the others is connected to a support frame 13 to ensure the overall support effect of the device. At the same time, the support frame 13 on one side is higher than the support frame 13 on the other side, which can ensure that the electrolyte can flow to the circulation pipe 14 during filtration.

[0027] Reference Figure 2As shown, the outer filter frame 2, the inner filter frame 5, and the water inlet frame 6 are all provided with a slag discharge trough 15 on one side. The outer filter frame 2 and the inner filter frame 5 are all connected to a filter screen 101 on one side. The electrolyte is filtered through the 101. As the outer filter frame 2, the inner filter frame 5, and the water inlet frame 6 rotate, the cleaning brush 7 cleans the impurities. The spiral-shaped cleaning brush 7 moves the cleaned impurities to one end and can finally be discharged through the slag discharge trough 15 and through the slag discharge pipe 8. A valve is connected to one end of the slag discharge pipe 8.

[0028] Reference Figure 2 As shown, a protective pad 4 is connected to one side of the inner wall of the outer casing 1. The outer filter frame 2, the inner filter frame 5 and the water inlet frame 6 are rotatably connected to the protective pad 4, which can effectively support and protect the outer filter frame 2, the inner filter frame 5 and the water inlet frame 6.

[0029] The implementation principle of this application is as follows: When this utility model is in use, the electrolyte to be filtered is discharged into the device through the support tube frame 3. At the same time, the drive motor 11 is started to drive the device to run through the transmission shaft 12. After the electrolyte enters the device, it passes through the water inlet frame 6 and enters the inner filter frame 5 for filtration. After filtration, it passes through the outer filter frame 2 for filtration and is finally discharged through the circulation pipe 14. During the filtration process, the rotation of the inner filter frame 5 and the outer filter frame 2 will continuously switch the filter surface to ensure the filtration effect. At the same time, the rotation drives the cleaning brush 7 to clean the filter screen 101 on one side of the inner filter frame 5 and the outer filter frame 2. Meanwhile, the external water source enters the water inlet pipe 9 and sprays the inner filter frame 5 and the outer filter frame 2 through the nozzle 10 to ensure the cleaning effect and push the impurities away from the circulation pipe 14.
