Description

Technical Field

[0001] This utility model relates to the field of electrophoretic coating technology, specifically to an aluminum alloy electrophoretic tank. Background Technology

[0002] Electrophoretic coating is a special coating film formation method suitable for electrodeposited coatings. It involves immersing a conductive workpiece in an electrophoretic tank diluted with pure water and containing low solids as the anode (or cathode). The electrophoretic tank also contains a corresponding cathode (or anode). A direct current is applied between the two electrodes for a certain period of time, resulting in the deposition of a uniform, water-insoluble coating film on the surface of the workpiece.

[0003] When preparing the electrophoresis solution, the coating itself will carry certain impurity ions. When the impurity ions react with the charged resin, they will form precipitates, which will damage the electrophoretic characteristics and stability of the coating. This will lead to local precipitation and uneven concentration of the electrophoresis solution used in the electrophoresis tank, which will affect the uniformity and consistency of the electrophoresis process, affect the coating quality, and reduce the coating effect.

[0004] Therefore, we propose an aluminum alloy electrophoresis tank to solve the problems mentioned above. Utility Model Content

[0010] By adopting the above technical solution, and designing the electrophoresis tank body as a structure combining an outer layer and an inner layer, it is possible to maintain a constant temperature of the electrophoresis solution, thereby further ensuring the stability and uniformity of the electrophoresis process and improving electrophoresis efficiency.

[0011] Preferably, a power connection port is provided at one corner of the electrophoresis tank body, and a grounding port is provided at the other corner of the electrophoresis tank body.

[0014] By adopting the above technical solution, a heating system is embedded inside the outer layer to ensure that the electrophoretic solution maintains an appropriate temperature during the electrophoresis process. The temperature sensor can monitor the temperature of the electrophoretic solution in real time to ensure that the heating temperature is moderate and to avoid the adverse effects of excessively high or low temperatures on the electrophoresis process, thereby improving the coating quality and effect.

[0015] Preferably, a filter box is provided on one side of the electrophoresis tank body, a return water pipe is connected to one side of the electrophoresis tank body, and the other end of the return water pipe is connected to the filter box.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The blower delivers air evenly to all areas of the electrophoresis tank through delivery pipes, connecting pipes, and aeration pipes. The aeration pipes disperse the air into the electrophoretic solution in the form of fine, uniform bubbles, improving the air circulation efficiency within the electrophoresis tank. This results in finer and more uniform bubbles in the electrophoretic solution, optimizing the electrophoresis process and improving coating quality and efficiency. Simultaneously, the uniform distribution of the aeration pipes ensures consistent electrophoresis effects across all areas of the electrophoresis tank, preventing localized sedimentation and uneven concentration. This allows impurity ions in the electrophoretic solution to be more evenly dispersed in the liquid, reducing localized sedimentation and uneven concentration, thus improving the uniformity of the electrophoresis process and ensuring consistent coating quality.

The filtered electrophoretic solution flows back into the electrophoresis tank through the outlet pipe and the second water pump, realizing the recycling of the electrophoretic solution. This circulating filtration system can continuously remove impurity ions from the electrophoretic solution, maintain its purity and stability, and thus ensure the smooth progress of the electrophoresis process and the coating quality.

The aeration pipe 10 and the connecting pipes 9 are designed to correspond to each other, and a clamping plate 11 is nested on the outer surface of the aeration pipe 10 to fix the position of the aeration pipe 10. When the blower 6 starts, air enters the electrophoresis tank through the delivery pipe 7 and is evenly distributed in various areas of the electrophoresis tank through the connecting pipe 9 and the aeration pipe 10. This helps to improve the air circulation efficiency in the electrophoresis tank, making the bubbles in the electrophoretic solution smaller and more uniform, thereby optimizing the electrophoresis process and improving coating quality and efficiency. At the same time, the uniform distribution of the aeration pipe 10 also ensures that the electrophoresis effect in various areas of the electrophoresis tank is consistent, avoiding local precipitation and uneven concentration.

The inner layer 102 uses heat-insulating material to reduce heat loss during electrophoresis and maintain the electrophoresis solution within a suitable temperature range. The aeration pipe 10 is L-shaped and extends to the bottom of the inner layer 102, which helps to ensure that the bubbles in the electrophoresis solution are evenly distributed, improving the electrophoresis efficiency. At the same time, the extension of the aeration pipe 10 also increases the contact area between the electrophoresis solution and the air, which helps to remove dissolved gases in the electrophoresis solution and reduce the impact of bubbles on the electrophoresis process.
