Description

Technical Field

[0001] The utility model relates to the technical field of electroplating tanks, and specifically relates to a circulating electroplating tank for electroplating solution. Background Art

[0002] The most basic equipment in electroplating equipment, whose main function is to hold the solution. The electroplating tank can be arranged in a straight line according to the manual operation process production line, or arranged according to different electroplating types according to the on-site space as the case may be. A circulating electroplating tank is an electroplating tank that circulates the electroplating solution through pipelines. It can effectively improve the uniformity and stability of the electroplating solution, thereby obtaining better electroplating effects. However, the currently used electroplating tanks still have problems such as uneven electroplating solution and easy contamination.

[0003] According to the patent with the publication number CN216786298U, a circulating electroplating tank for electroplating solution is disclosed, which includes an electroplating box, and a circulating box is fixedly connected to the left side of the electroplating box. In the utility model, the lifting cylinder is started to lift the electroplating box, so that the used electroplating solution inside the electroplating box can be discharged into the circulating box through the liquid passing holes on the left side. There are three groups of filter meshes inside the filter rack to filter the filter residues in the reflux liquid. Pulling up the filter rack and the sealing cover can supplement the plating metal. There is a pH detection probe on the right side of the detector, so that the reflux liquid at the top of the partition plate can detect the pH value of the reflux liquid, and the acid solution can be supplemented through the detector. The driving motor rotates the stirring rack so that the internal reflux liquid can be fully mixed with the supplementary materials. After the mixing is completed and the detection is qualified, the solenoid valve can be opened to recycle the liquid flowing back to the bottom of the partition plate. Such a circulating electroplating tank can effectively ensure the quality of the circulating electroplating solution and ensure the electroplating effect.

[0004] In the above case, the driving motor rotates the stirring rack so that the internal reflux liquid can be fully mixed with the supplementary materials. After the mixing is completed and the detection is qualified, the solenoid valve can be opened to recycle the liquid flowing back to the bottom of the partition plate. Such a circulating electroplating tank can effectively ensure the quality of the circulating electroplating solution and ensure the electroplating effect. However, the applicant believes that the impurities in the electroplating solution cannot be removed in the electroplating tanks in the prior art, and the electroplating solution needs to be recycled. Once there are impurities in the used electroplating solution, it will affect the secondary operation of the electroplating tank at this time, thereby reducing the practicability of the device.

[0005] The purpose of the utility model is to provide a circulating electroplating tank for electroplating solution, aiming to effectively solve the problem that the impurities in the electroplating solution cannot be removed in the electroplating tanks in the prior art, and the electroplating solution needs to be recycled. Once there are impurities in the used electroplating solution, it will affect the secondary operation of the electroplating tank at this time.

[0006] To solve the above problems, the utility model adopts the following technical solutions:

[0007] An electroplating solution circulation type electroplating tank, comprising an electroplating tank main body and a circulating liquid unit. A liquid outlet is opened below one side of the electroplating tank main body. A filter screen is fixedly connected at the liquid outlet. A scraper is arranged inside the electroplating tank main body and close to the liquid outlet, and the scraper is attached to the surface of the filter screen.

[0008] The circulating liquid unit includes a liquid collecting tank fixedly connected to the outer wall of the electroplating tank main body and at the liquid outlet.

The other end of the liquid return pipe is fixedly connected to the inside of the electroplating tank main body. The electroplating solution is filtered through the filter screen at the liquid outlet and then conveyed to the liquid collecting tank. After filtration, the electroplating solution is sent back to the inside of the electroplating tank main body through the liquid delivery pipe, the circulating water pump and the liquid return pipe, improving the use efficiency of the electroplating solution. Later, the impurities attached to the surface of the filter screen can be scraped off by the scraper, ensuring the filtering efficiency of the filter screen for the impurities in the electroplating solution.

After filtration, the electroplating solution is sent back to the inside of the electroplating tank main body through the liquid delivery pipe, the circulating water pump and the liquid return pipe, improving the use efficiency of the electroplating solution. Later, the impurities attached to the surface of the filter screen can be scraped off by the scraper, ensuring the filtering efficiency of the filter screen for the impurities in the electroplating solution.

[0016] (2) Enable the drive motor to drive the first gear to rotate forward or backward. While the first gear rotates, it drives the meshing-connected second gear to rotate.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1 and Figure 2, An electroplating solution circulating electroplating tank, comprising an electroplating tank main body 1 and a circulating liquid unit 3. A liquid outlet 2 is provided below one side of the electroplating tank main body 1. A filter screen 4 is fixedly connected at the liquid outlet 2. A scraper 5 is arranged inside the electroplating tank main body 1 and close to the liquid outlet 2. The scraper 5 is attached to the surface of the filter screen 4. The circulating liquid unit 3 includes a liquid collecting tank 301 fixedly connected to the outer wall of the electroplating tank main body 1 and at the liquid outlet 2. The other side of the liquid collecting tank 301 is fixedly connected with a liquid delivery pipe 302. The other end of the liquid delivery pipe 302 is fixedly connected with a circulating water pump 303. The other side of the circulating water pump 303 is fixedly connected with a liquid return pipe 304. The other end of the liquid return pipe 304 is fixedly connected to the inside of the electroplating tank main body 1.

[0026] In this embodiment, the electroplating solution is placed inside the electroplating tank main body 1. The circulating water pump 303 is activated to generate negative pressure at the liquid outlet 2. The electroplating solution is filtered through the filter screen 4 at the liquid outlet 2 and conveyed to the liquid collecting tank 301. After filtration, the electroplating solution is sent back into the electroplating tank main body 1 through the liquid delivery pipe 302, the circulating water pump 303 and the liquid return pipe 304, improving the utilization efficiency of the electroplating solution. Later, the impurities attached to the surface of the filter screen 4 can be scraped off by the scraper 5 to ensure the filtering efficiency of the filter screen 4 for impurities in the electroplating solution.

[0027] Please refer to Figure 2 and Figure 3 , A threaded rod 6 is rotatably connected to one side inside the electroplating tank main body 1. The threaded rod 6 is threadedly connected to one side of the scraper 5. A driving motor 7 is fixedly installed above one side of the electroplating tank main body 1. The output end of the driving motor 7 is fixedly connected with a first gear 8. The upper end of the threaded rod 6 extends above the electroplating tank main body 1 and is fixedly connected with a second gear 9. The second gear 9 is meshed with the first gear 8.

[0028] In a further embodiment, activating the driving motor 7 can drive the first gear 8 to rotate forward or backward. While the first gear 8 rotates, it drives the meshed second gear 9 to rotate. While the second gear 9 rotates, it drives the threaded rod 6 to rotate. Since the threaded rod 6 is threadedly connected to the scraper 5, the threaded rod 6 drives the scraper 5 to automatically lift and lower to clean the filter screen 4 while rotating.

[0029] Please refer to Figure 4 , A guide rod 10 is fixedly connected to the other side inside the electroplating tank main body 1. The guide rod 10 is slidably connected to the other side of the scraper 5. While one side of the scraper 5 lifts and lowers along the threaded rod 6, the other side of the scraper 5 slides along the guide rod 10, thus ensuring the stability of the lifting and lowering of the scraper 5.

[0030] Specifically, please refer to Figure 4, a collection tank 12 is fixedly connected to the outer wall of one side of the electroplating tank body 1 close to the liquid outlet 2. An outlet 11 is provided on the outer wall of the electroplating tank body 1 and above the collection tank 12, and the outlet 11 communicates with the collection tank 12. The scraper 5 conveys the impurities on the filter screen 4 upward along the inner wall of the electroplating tank body 1. When the scraper 5 moves to the outlet 11, the impurities are introduced into the collection tank 12 along the inclined outlet 11 for centralized collection for later centralized treatment.

[0031] Working principle:

[0032] When the present utility model is in use, the electroplated parts are placed inside the electroplating tank body 1, and at the same time, the electroplating solution is placed inside the electroplating tank body 1. The circulating water pump 303 is activated to generate negative pressure at the liquid outlet 2, and the electroplating solution is filtered through the filter screen 4 at the liquid outlet 2 and conveyed to the liquid collecting tank 301. After filtration, the electroplating solution is sent back into the electroplating tank body 1 through the liquid supply pipe 302, the circulating water pump 303 and the liquid return pipe 304, improving the utilization efficiency of the electroplating solution. Later, the impurities attached to the surface of the filter screen 4 can be scraped off by the scraper 5 to ensure the filtering efficiency of the filter screen 4 for the impurities in the electroplating solution. The driving motor 7 is activated to drive the first gear 8 to rotate forward or backward. While the first gear 8 rotates, it drives the meshing second gear 9 to rotate. While the second gear 9 rotates, it drives the threaded rod 6 to rotate. Since the threaded rod 6 is threadedly connected to the scraper 5, the threaded rod 6 drives the scraper 5 to automatically lift and lower to clean the filter screen 4 while rotating. The scraper 5 conveys the impurities on the filter screen 4 upward along the inner wall of the electroplating tank body 1. When the scraper 5 moves to the outlet 11, the impurities are introduced into the collection tank 12 along the inclined outlet 11 for centralized collection for later centralized treatment.

For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to enumerate all the implementation modes here. Any obvious changes or variations derived from the technical solutions of the present utility model still fall within the protection scope of the present utility model.
