Description

TECHNICAL FIELD

[0001] The utility model relates to the field of electroplating technology, especially to a kind of anti-blocking overflow tank. BACKGROUND

[0002] When metal is used in various different environments, metal corrosion will occur due to the chemical and electrochemical effects of external media on the metal surface. Electroplating can form a dense plating layer on the metal surface, effectively isolating the metal from the corrosive medium, thereby improving the corrosion resistance of the metal.

[0003] The related technology can refer to the Chinese patent with the publication number CN218710966U, which discloses an electroplating liquid circulating type electroplating tank, including an electroplating tank body, a liquid outlet hole is formed at the bottom end of the side wall of the electroplating tank body, a sealing ring is bonded inside the liquid outlet hole, a liquid outlet pipe is fixedly sleeved inside the sealing ring, four limiting sliding grooves are formed in a circular array on one side of the inner wall of the liquid outlet pipe, a filter screen is clamped on one side of the inner wall of the liquid outlet pipe through the limiting sliding grooves, and the electroplating liquid circulating type electroplating tank is provided with a filter screen. When the electroplating liquid needs to be recycled, the centrifugal pump inside the electroplating liquid circulating assembly is started, and then the centrifugal pump will absorb the electroplating liquid at the bottom end inside the electroplating tank body through the first circulating pipe and the liquid outlet pipe. When the electroplating liquid passes through the liquid outlet pipe, the filter screen arranged inside the liquid outlet pipe will filter the impurities contained in the electroplating liquid, so that the electroplating liquid used again does not contain impurities, thereby facilitating the secondary work of the electroplating tank body and enhancing the practicality of the device.

[0004] According to the related technology in the above, the overflow tank filters the overflowed electroplating liquid through the filter screen. The electroplating liquid contains a large amount of particulate matter. With the passage of time, these particulate matters will be continuously intercepted by the filter screen and gradually accumulate on the filter screen. Therefore, the filter screen needs to be disassembled and cleaned. During the disassembly and cleaning process, the overflow tank cannot filter the electroplating liquid, which reduces the working efficiency of the overflow tank. SUMMARY
