Description

Technical Field

[0001] The utility model relates to the technical field of electroplating water washing equipment, in particular to a multi-stage countercurrent water washing structure. Background Art

[0002] In electroplating equipment, when washing products with water, overflow multi-stage water washing is often used in order to clean the products and save water as much as possible.

[0003] The current common overflow method has the problem of water cross-contamination. When the product is placed into the first tank too quickly, if the overflow drain plate of the first tank is not draining quickly enough, the water level will rise above the overflow plate between the first and second tanks. This will cause the first wash water with the most impurities to flow into the second wash tank, which is relatively clean. This will cause contamination of the subsequent tank liquid, affecting the product cleaning effect and the electroplating quality.

[0004] Therefore, it is necessary to design a multi-stage water washing structure that can avoid water cross-contamination. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a multi-stage countercurrent water washing structure, which has a simple structure, can avoid water cross-flow, and ensure the product cleaning effect.

Except for the first water washing tank, all the water washing tanks are provided with an overflow structure, and a floating sealing component is provided in the overflow structure for sealing backflow.

[0008] Optionally, in one embodiment of the present invention, the overflow structure includes an overflow cover, an overflow plate, a water inlet and a water outlet, the water inlet is arranged on the overflow cover, the overflow cover is located at the upper end of the overflow structure, the overflow plate is located on the side of the overflow structure, and the water outlet is opened at the lower end of the overflow structure.

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments. Example

[0022] In order to ensure the cleaning effect of the product and prevent water from flowing through, a multi-stage countercurrent washing structure is designed. The specific scheme is as follows:

[0023] like Figure 1-2As shown, a multi-stage countercurrent water washing structure includes a tank body 1, in which multiple water washing tanks 2 are arranged. A liquid level difference is maintained between each water washing tank 2. The first water washing tank 2 is provided with an overflow drainage plate 5, and a drainage port is provided at the bottom of the water washing tank 2 inside the overflow drainage plate 5. Except for the first water washing tank 2, all water washing tanks 2 are provided with an overflow structure 4. A floating sealing component is provided in the overflow structure 4 for sealing backflow.

[0024] There are three water washing tanks 2 in the tank body 1, which are used for three-level water washing of products. The electroplated parts are washed three times to ensure the cleaning effect. The water washing tanks 2 are separated by partitions. The partitions and the tank body 1 are an integrated structure and the height of the partitions is the same as the height of the tank body 1.

[0025] The overflow structure 4 includes an overflow cover 402, an overflow plate 403, a water inlet and a water outlet 405. The water inlet is arranged on the overflow cover 402, the overflow cover 402 is located at the upper end of the overflow structure 4, the overflow plate 403 is located on the side of the overflow structure 4, and the water outlet 405 is opened at the lower end of the overflow structure 4. The bottom surface of the overflow cover 402 is an inverted funnel structure. When the PE float floats up, the PE float contacts the bottom surface of the overflow cover 402, which can make the PE float move toward the center of the overflow cover 402 to ensure the sealing effect. A circular overflow hole 401 is opened in the center of the overflow cover 402.

[0026] The overflow structure 4 at the rear exceeds the overflow structure 4 at the front to ensure the overflow effect of the rear water washing tank 2 and the front water washing tank 2, while preventing the sewage from the front water washing tank 2 from flowing to the rear water washing tank 2. Similarly, the height of the overflow drainage plate 5 is lower than the overflow structure 4 of the rear water washing tank 2. For example, when the liquid level of the first water washing tank 2 rises, the sewage will not flow back to the second water washing tank 2 through the overflow structure 4. The excess sewage will be discharged through the overflow drainage plate 5 position, discharging part of the sewage. At the same time, the subsequent water replenishment can replenish relatively clean water into the first water washing tank 2, ensuring that the water in the first water washing tank 2 is not too dirty and affects the cleaning effect of the product.

[0027] The electroplated parts are first placed in the first water washing tank 2 for cleaning, and then placed in the second water washing tank 2, and then in the third water washing tank 2 for cleaning. The closer the water washing tank 2 is to the back, the cleaner the cleaning water inside. The last water washing tank 2 is connected to the water inlet pipe 3. When the liquid level of the water washing tank 2 is too low, the third water washing tank 2 can be replenished with water through the water inlet pipe 3. After the water in the third water washing tank 2 is replenished, the excess water inside can be used to replenish the second water washing tank 2 through the overflow structure 4. Similarly, the excess water in the second water washing tank 2 is used to replenish the first water washing tank 2, which is more convenient to use and there is no need to replenish water for each water washing tank 2 separately.

[0028] The overflow structure 4 is provided at the corners of each washing tank 2 . The overflow structure 4 is a triangular prism structure as a whole, ensuring that the washing tank 2 has a larger space for product washing.

[0029] In this embodiment, the floating sealing component 404 is a PE float ball, which has a density lower than that of water and can float on the water surface. In other solutions, the floating sealing component 404 can also be made of other materials with a density lower than that of water.

[0030] A bracket 6 is provided at the bottom of the tank body 1. The setting of the bracket 6 increases the height of the tank body 1, making it easier for staff to operate. At the same time, it is easier for staff to check the bottom of the tank body 1 and the pipes at the bottom, making it easier to replace and repair.

[0031] The water washing structure of this scheme has a simple structure. The tank body 1 is divided into multiple water washing tanks 2, which can provide multi-stage cleaning for the product to ensure that the product can be cleaned. Water can be replenished and circulated between the water washing tanks 2 through the overflow structure 4. At the same time, a floating sealing component 404 is provided in the overflow structure 4 to prevent the sewage from the previous water washing tank 2 from contaminating the next water washing tank 2, thereby ensuring the cleaning effect of the product and improving the quality of the electroplating product. Because the cleaning water of the water washing tank 2 can be replenished and circulated, it is ensured that the water washing structure can be fully utilized, which saves water and reduces the water cost of the enterprise.
