Description

Technical Field

[0001] This utility model relates to the field of electrolyte filtration technology, specifically to an electrolyte circulation filtration device for foil production machines. Background Technology

[0002] Circulating and filtering the electrolyte within the copper foil production machine is a crucial step in ensuring the quality and efficiency of copper foil production. During the electrolytic deposition process, anode dissolution produces particulate impurities such as copper powder, while the cathode generates organic flocculants due to the decomposition of additives. These impurities, suspended in the electrolyte, will adhere to the surface of the cathode roller if left untreated, leading to uneven deposition and fatal defects in the copper foil, such as pinholes, burrs, and thickness fluctuations, severely reducing the product yield.

[0003] A circulating filtration device for electrolyte in electrolytic processing, disclosed in patent publication number CN209123462U, includes a main rotating shaft and stirring blades. In use, the device is placed in a suitable position. After electrolysis is completed inside the electrolytic cell, the first water pump is turned on to draw the electrolyte into the filter slot. The stirring motor is then turned on, driving the main rotating shaft and stirring blades to stir the electrolyte inside the assembled filter screen. This, combined with the assembled filter screen, ensures complete initial filtration of the electrolyte with high efficiency. The detachable motor bracket and the assembled filter screen are easy to clean. After initial filtration, the solenoid valve is opened, allowing the pre-filtered electrolyte to enter through the drain pipe. A fine filter screen installed inside the insertion block provides secondary filtration of the electrolyte inside the drain pipe. The insertion block and fine filter screen can be pulled out using a handle for cleaning. The second water pump is then turned on to transport the filtered electrolyte back to the electrolytic cell through the drain pipe and inlet pipe for reuse.

[0004] The above-mentioned device requires the machine to be stopped and the entire assembled filter screen to be disassembled and removed for cleaning after filtering the electrolyte. After cleaning, it needs to be reinstalled, which is quite troublesome and affects work efficiency. In order to address the above problems, an electrolyte circulation filtration device for foil making machine is proposed. Utility Model Content

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] Please see Figures 1-4In this embodiment, the electrolyte circulation filtration device for the foil production machine includes a housing 11 and a filter cylinder 12 rotatably disposed inside the housing 11. A sealing cover 15 is provided on one side of the housing 11, and a rotating assembly for driving the filter cylinder 12 to rotate is provided on one side of the sealing cover 15. A spraying assembly for cleaning the filter cylinder 12 is provided inside the housing 11.

[0026] The spraying assembly includes a water tank 20 and a spray pipe 21. The water tank 20 is fixedly connected to the top of the housing 11. The spray pipe 21 is installed on the top of the inner wall of the housing 11. A pump body 22 is installed inside the water tank 20. The inlet of the pump body 22 is connected to a suction pipe 23. The outlet of the pump body 22 is connected to the spray pipe 21. A collection slot 28 is provided inside the filter cartridge 12. The opening of the collection slot 28 corresponds to the spray nozzle of the spray pipe 21. A storage container for collection is provided on one side of the collection slot 28. During cleaning, the delivery of electrolyte is stopped first. While the filter cartridge 12 continues to rotate, the pump 22 inside the water tank 20 starts, and water in the water tank 20 is transported to the spray pipe 21 through the suction pipe 23 to rinse the filter cartridge 12, washing away the impurities attached to the inner wall of the filter cartridge 12. During rinsing, since the spray pipe 21 is opposite to the collection tank 28, the water sprayed from the spray pipe 21 washes the impurities into the collection tank 28, where the collection tank 28 collects the water and impurities. The storage unit sucks up and collects the impurities and water in the collection tank 28, so the filter cartridge 12 can be cleaned without disassembly, reducing disassembly and installation time and improving work efficiency.

[0027] The housing 11 is provided with a limiting component for guiding and supporting the rotation of the filter cartridge 12, and an outlet pipe 32 is installed on the side of the housing 11 away from the sealing cover 15.

[0028] The rotating assembly includes a rotating block 13 and a gear ring 17. The rotating block 13 is fixedly connected to one side of the filter cylinder 12. The inner wall of the gear ring 17 is fixedly connected to the outer wall of the rotating block 13. The inner walls of the housing 11 and the sealing cover 15 are both provided with rotating grooves 14 for rotating in conjunction with the rotating block 13. Two sets of support frames 16 are fixedly connected to one side of the housing 11. The end of the support frame 16 away from the housing 11 is fixedly connected to one side of the sealing cover 15. The gear ring 17 is meshed with a gear 18. A motor 19 is installed on one side of the water tank 20 to drive the gear 18 to rotate. When the motor 19 is started, it drives the gear 18 to rotate. The gear ring 17 drives the rotating block 13 to rotate in the rotating groove 14 through meshing with the gear 18. The rotating block 13 drives the filter cylinder 12 to rotate, which facilitates the filtration of the electrolyte.

[0029] The storage device includes a collection pipe 29 and a collection box 30. The collection pipe 29 is installed on the sealing cover 15. A second pump body is installed inside the collection box 30. The inlet of the second pump body is connected to the outlet of the collection pipe 29. The inlet of the collection pipe 29 is connected to the outlet of the storage tank 28. An electric one-way valve is installed at the inlet of the collection pipe 29. When the second pump body in the collection box 30 is activated, it draws and collects impurities and water in the storage tank 28 through the collection pipe 29, reducing the number of times the filter cartridge 12 needs to be disassembled for cleaning. At the same time, the electric one-way valve can prevent the electrolyte from entering the collection pipe 29 through the storage tank 28 during filtration. The electric one-way valve is prior art and will not be described in detail in this application.

[0030] The limiting component includes a limiting block 24 and a limiting groove 25. The limiting block 24 is fixedly connected to the bottom of the inner wall of the housing 11. The limiting groove 25 is opened on the outer surface of the filter cylinder 12. The limiting block 24 is slidably connected in the limiting groove 25. When the filter cylinder 12 rotates, the limiting groove 25 rotates on the limiting block 24, which can support and guide the rotation of the filter cylinder 12 and prevent the filter cylinder 12 from shaking when rotating.

[0031] A fixing rod 26 is fixedly connected to one side of the inner wall of the housing 11. Several sets of support rods 27 are fixedly connected to the bottom of the collection tank 28. The end of the support rod 27 away from the collection tank 28 is connected to the fixing rod 26. The fixing rod 26 is rotatably connected to the filter cylinder 12, which can support and limit the collection tank 28 to prevent the collection tank 28 from shaking or misaligning during filtration, resulting in incomplete collection of sprayed water and impurities.

[0032] The sealing cover 15 is equipped with a liquid inlet pipe 31. By setting the liquid inlet pipe 31, it can be connected to the liquid outlet at the bottom or side of the electrolytic cell, which facilitates the transportation of electrolyte.

[0033] The working principle of this utility model is as follows: In use, first connect the inlet pipe 31 to the outlet at the bottom or side of the electrolytic cell, then connect the outlet pipe 32 to the existing circulating pump, and then connect the return pipe to the inlet of the electrolytic cell of the foil-making machine. The electrolyte to be filtered enters the filter cylinder 12 through the inlet pipe 31. The motor 19 starts, driving the gear 18 to rotate. The gear ring 17, through meshing with the gear 18, drives the rotating block 13 to rotate within the rotating groove 14. The rotating block 13 drives the filter cylinder 12 to rotate. When the filter cylinder 12 rotates, the limiting groove 25 rotates on the limiting block 24, filtering the electrolyte. The filtered electrolyte enters the existing circulating pump through the outlet pipe 32, and then flows through the return pipe on one side of the circulating pump. The filter cartridge 12 enters the electrolytic cell of the foil-making machine for circulating filtration. During cleaning, the supply of electrolyte is first stopped, the filter cartridge 12 continues to rotate, and the pump 22 in the water tank 20 is started. Water from the water tank 20 is transported to the spray pipe 21 through the suction pipe 23 to rinse the filter cartridge 12, washing off the impurities adhering to the inner wall of the filter cartridge 12. During rinsing, since the spray pipe 21 is opposite to the collection tank 28, the water sprayed from the spray pipe 21 washes the impurities into the collection tank 28, where the water and impurities are collected. The pump 2 in the collection box 30 is started, and the impurities and water in the collection tank 28 are sucked up and collected through the collection pipe 29. The filter cartridge 12 can be cleaned without disassembly, reducing disassembly and installation time and improving work efficiency.
