[0002] Electroplating solution circulation filtration refers to a process operation in which the plating solution in the electroplating tank is continuously circulated through specific equipment and devices, and impurities, particles, suspended solids and other harmful substances are removed by the filter medium to maintain the cleanliness and stability of the plating solution, and to ensure the normal operation of the electroplating process and the quality of the electroplated products.

[0003] Currently, electroplating processes utilize multiple filter frames to circulate and filter the electroplating solution. However, this process requires disassembling and cleaning these multiple filter frames over time, followed by cleaning the surface impurities. This is time-consuming and labor-intensive, impacting the actual cleaning efficiency. Therefore, there is a need for an electroplating solution circulation filtration device that can address these drawbacks and improve the overall performance. Utility Model Content

[0024] 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.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 As shown, this utility model is a circulating filtration device for electroplating processing, comprising:

[0027] The plating solution filtration mechanism includes a filter frame 11, and filter screens 15 are provided at equal intervals on the inner wall of the filter frame 11. The aperture of the multiple filter screens 15 is gradually increased or decreased from the inside to the outside.

[0028] The filter frame 11 provides a structural installation environment, and the filter mesh frame 15 with multiple pore sizes that gradually decrease can complete the filtration treatment of the electroplating solution in stages.

[0029] The plating solution filtration mechanism also includes a connecting frame 12, which is symmetrically fixed at the front and rear ends of the filter frame 11. The corners of the connecting frame 12 are provided with threaded holes 14 and extend into the electroplating tank.

[0030] A locking bolt 13 is threaded in the threaded hole 14, and a locking nut is threaded at one end of the locking bolt 13, which abuts against the electroplating tank.

[0031] The connecting hole receives the locking bolt 13, and the connecting bracket 12 is fixed by locking the locking nut, thereby installing and fixing the filter frame 11. The threaded connection is easy to disassemble and assemble.

[0032] A connecting pipe 16 is provided through the middle of one side of the upper end of the filter frame 11, and a circulation conveying pipe 17 is provided in the middle of the connecting pipe 16 with internal thread.

[0033] Connector 16 connects the circulation delivery pipe 17 to the filter frame 11 to circulate and deliver the electroplating solution to complete the circulatory filtration.

[0034] A movable plate 18 is fixedly connected to the top of the filter frame 15 and extends into the top of the filter frame 11. A movable handle 19 is fixed in the middle of the upper end of the movable plate 18, and a sealing gasket is filled in the joint between the movable plate 18 and the filter frame 11.

[0035] The movable plate 18 is used to install multiple filter frames 15. The filter frames 15 can be disassembled and assembled by the movable handle 19, while the sealing gasket ensures the sealing of the connection gap between the two.

[0036] The auxiliary cleaning mechanism includes a mounting block 31. The mounting block 31 is symmetrically threaded to both sides of the top center of the inner wall of the filter frame 11. A support block 32 is fixed to the bottom center of the mounting block 31. Cleaning brushes 33 are fixedly connected to the front and rear ends of the inner support block 32 and the rear ends of the outer support block 32, and are in contact with the surfaces of multiple filter frames 15.

[0037] The mounting block 31 is fixed to the cleaning brush 33 by the support block 32. During the process of disassembling and removing multiple filter frames 15, the surface of the filter frames 15 can be actively cleaned by the contact and movement between the multiple cleaning brushes 33 and the filter frames 15. After the multiple filter frames 15 are removed from the filter frame 11, a simple secondary cleaning can be performed manually.

[0038] This solution allows for the proactive initial cleaning of impurities on the surface of the filter frame 15 during the disassembly process. Subsequent simple secondary cleaning can be performed manually, ensuring cleaning effectiveness while reducing labor intensity and time, saving time and effort, improving cleaning efficiency, and making it convenient to use.

[0039] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0040] A one-way limiting mechanism includes a through-hole 21, which is located at the lower part of one side of the electroplating tank. A hole block 22 is fixedly connected to the upper part of the outer side of the through-hole 21. A torsion spring 23 is provided through the middle of the hole block 22. A one-way limiting plate 25 is provided on the inner side of a set of torsion springs 23 and abuts against the outer wall of the through-hole 21.

[0041] A movable column 24 is fixed to the upper end of the one-way limiting plate 25, and the end of the movable column 24 is fixed to the inner side of a set of torsion springs 23.

[0042] The opening 21 allows the electroplating solution to flow through. The one-way limiting plate is installed and fixed by the movable column 24 through the hole block 22 and the torsion spring 23. The one-way limiting plate can be opened and moved on one side to allow the electroplating solution to flow through the electroplating tank. When the electroplating solution is circulating, the liquid flowing in the opposite direction acts on the one-way limiting plate 25. The liquid can avoid flow by abutting against the outer wall of the opening 21. At the same time, it can prevent the filter screen frame 15 from falling when it is disassembled and cleaned of internal impurities.

[0043] Working principle: In the above-mentioned process of circulating filtration of plating solution, the plating solution initially filtered is subjected to the one-way limiting plate 25 through the port 21, causing the movable one-way limiting plate 25 to move and unfold to one side, so that the plating solution initially filtered can smoothly enter the filter frame 11 and be filtered by multiple multi-filter mesh frames. In the subsequent circulating filtration of plating solution, it is directly transported to the filter frame 11 through the circulation conveying pipe 17. When the one-way limiting plate 25 is applied at this time, it can prevent the circulating filtered plating solution from flowing back into the electroplating tank by contacting the outer wall of the port 21. Furthermore, when the filter frame 11 is disassembled for internal impurity cleaning, the one-way limiting plate 25 can isolate the port 21.

[0044] This solution not only satisfies the filtration requirements of the circulating plating solution but also isolates the impurities removed during subsequent cleaning, improving structural applicability and functionality to meet the needs.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described.

This utility model is limited only by the claims and their full scope and equivalents.
