[0003] Chinese Patent CN217677850U ​​discloses an electrophoresis tank liquid circulation system, including an electrophoresis tank body, a filter box, and a water pump. The electrophoresis tank body is provided with a circulation transmission mechanism for recycling on the side near the filter box. A filter screen frame is provided inside the chute, and a limiting mechanism for fixing the position of the filter screen frame is provided at the bottom of the chute. The device uses a water pump to transport the electrophoresis liquid in the electrophoresis tank body to the inside of the filter box through a first water pipe. After the electroplating liquid is filtered layer by layer through multiple filter screen frames, it is discharged into the electrophoresis tank body through a second water pipe, thus achieving the effect of recycling.

[0018] Example 1

[0019] like Figures 1 to 4 As shown, the present invention proposes an electrophoresis tank liquid circulation system, including an electrophoresis tank body 1 and a cleaning mechanism; a rotating pipe 202 is provided at the bottom of the electrophoresis tank body 1, and the bottom end of the rotating pipe 202 extends to the outside of the bottom end of the electrophoresis tank body 1 and is connected to a connecting pipe 201. The other end of the connecting pipe 201 is connected to a filter mechanism 3 on the side wall of the electrophoresis tank body 1 through a circulation pump. The filter mechanism 3 is the prior art and can filter the electrolyte inside the electrophoresis tank body 1 step by step. The cleaning mechanism includes a sealing plate 5, a collection box 502, a return pipe 4, and an air supply pipe 504. The sealing plate 5 is connected to one side wall of the electrophoresis tank 1, and an overflow port 501 is provided on the sealing plate 5. The collection box 502 is installed on the outer wall of the sealing plate 5 and is located outside the overflow port 501. The return pipe 4 is installed on the sealing plate 5 and distributed inside the electrophoresis tank 1. The return pipe 4 is designed in a U-shape, and multiple sets of liquid outlet pipes 401 are evenly installed on the inner wall of the return pipe 4. The output end of the filter mechanism 3 is connected to the input end of the return pipe 4 through the overflow pipe 301. The air supply pipe 504 is installed on the top of the return pipe 4 and on the side away from the sealing plate 5 through a support rod 503. Multiple sets of air outlets 505 are evenly inclinedly installed on the air supply pipe 504, and the input end of the air supply pipe 504 is connected to an external blower mechanism.

[0020] Furthermore, the bottom of the collection box 502 is provided with an inclined part to facilitate the guidance of the foam discharged from the overflow port 501 into the collection box 502. The bottom of the collection box 502 is provided with a drain valve. By periodically opening the drain valve, the wastewater used to rinse the collection box 502 can be discharged.

[0021] Furthermore, the installation position of the reflux pipe 4 relative to the sealing plate 5 is lower than the installation position of the overflow port 501 relative to the sealing plate 5. Both the reflux pipe 4 and the liquid outlet pipe 401 are made of materials with high stability to avoid being affected by the electrolyte.

[0022] Furthermore, the side wall of the electrophoresis tank 1 is provided with a clearance opening 102 and a storage groove 103. The clearance opening 102 is connected to the storage groove 103. The sealing plate 5 is inserted into the storage groove 103. The sealing plate 5 is driven by the first hydraulic rod on the outer wall of the electrophoresis tank 1 to move and adjust along the height direction of the storage groove 103. The end of the return pipe 4 away from the sealing plate 5 is driven by the second hydraulic rod installed on the outer wall of the electrophoresis tank 1 to move and adjust along the height direction of the electrophoresis tank 1. The return pipe 4 moves synchronously with the sealing plate 5.

[0023] In this embodiment, an appropriate amount of electrolyte is injected into the electrophoresis tank 1. An aluminum profile is placed into the electrophoresis tank 1 using a robotic arm, submerging it in the electrolyte and causing it to move within the electrolyte, thus agitating it. The electrophoresis tank 1 is then activated to perform electrophoresis on the aluminum profile. A circulation pump is started, drawing the electrolyte from the electrophoresis tank 1 through the rotating tube 202 and transporting it along the connecting tube 201 to the filtration mechanism 3 for step-by-step filtration. The filtered electrolyte then flows along the overflow... Overflow from the overflow pipe 301 into the return pipe 4, and sprayed out by multiple sets of outlet pipes 401 below the electrolyte level in the electrophoresis tank 1, allowing for electrolyte recycling and resource conservation. The sealing plate 5 and the return pipe 4 are adjusted along the height of the receiving tank 103 and the electrophoresis tank 1 respectively, until the overflow port 501 is flush with the electrolyte level in the electrophoresis tank 1. Since one end of the return pipe 4 is mounted on the sealing plate 5... Furthermore, it is located below the overflow port 501, ensuring that the return pipe 4 is always below the electrolyte surface. The outlet pipe 401 then sprays the filtered electrolyte into the electrolyte compartment 1, preventing contact with air above the liquid surface and reducing bubble formation. As the aluminum profile moves in the electrolyte, bubbles rise and accumulate on the surface. An external blower mechanism is connected to the input end of the air supply pipe 504, supplying air into the pipe 504, which then flows through multiple air outlets 505. The air is blown downwards towards the electrolyte surface inside the electrophoresis tank 1. Under the action of the wind, the air bubbles on the surface of the liquid move towards the overflow port 501 until they enter the collection box 502 along the overflow port 501 and are collected. This can clean up the air bubbles generated during electrophoresis and prevent them from interfering with the electrophoresis process. The sealing plate 5 and the return pipe 4 can be used to adjust the vertical direction along the collection tank 103 and the electrophoresis tank 1, which can adapt to electrophoresis processing at different liquid levels and has a wider range of applications.

[0024] Example 2

[0025] like Figure 2 and Figure 3As shown, the electrophoresis tank liquid circulation system proposed in this utility model, compared with Embodiment 1, has multiple sets of rotating tubes 202. A bracket 2 is installed at the bottom of the electrophoresis tank 1, and a driving mechanism is installed on the bracket 2. The multiple sets of rotating tubes 202 are driven to rotate and connected to the electrophoresis tank 1 through the driving mechanism. The driving mechanism consists of a motor, a reducer and a chain drive assembly. A connecting tube 201 is installed on the bracket 2. The output ends of the multiple sets of rotating tubes 202 are rotatably connected to the corresponding input ends on the connecting tube 201. A stirring blade 203 is installed on the side wall of the rotating tube 202, and the stirring blade 203 is distributed inside the electrophoresis tank 1.

[0026] Furthermore, a protective net 101 is detachably installed on the inner wall of the electrophoresis tank 1, and the protective net 101 is located above the rotating tube 202.

[0027] In this embodiment, the controller starts the drive mechanism to drive multiple sets of rotating tubes 202 to rotate along the electrophoresis tank 1, thereby driving multiple sets of stirring blades 203 to rotate. This can stir the electrolyte inside the electrophoresis tank 1, prevent precipitation from affecting the electrophoresis efficiency, and further improve the processing efficiency. The protective net 101 is set to protect the aluminum profiles placed inside the electrophoresis tank 1, prevent them from contacting the stirring blades 203 and causing damage, and improve the safety of use.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
