[0002] Elevators and their electrophoresis tanks are widely used in various industries. Electrophoresis tanks are typically used for coating metal surfaces, improving corrosion resistance and aesthetics through electrophoretic coating technology. The combined application of elevators and electrophoresis tanks, especially in the production and maintenance of modern elevators, ensures the durability and appearance quality of elevator components.

[0003] Traditional electrophoresis tanks typically consist of a tank body, a power supply system, a liquid circulation system, and a temperature control system. The tank body holds the processing solution, the power supply system provides the necessary current, the liquid circulation system ensures the uniform distribution of the processing solution, and the temperature control system maintains the appropriate temperature for the electrophoresis process to ensure coating quality.

[0004] Impurities in traditional electrophoresis tanks have a significant impact on electrophoretic coatings. This is typically because impurities interfere with the electric field distribution and liquid flow during the electrophoretic coating process, affecting the uniformity of the coating. Impurities can adhere to the coating surface, causing unevenness or defects such as blistering, cracking, or peeling. These coating inhomogeneities and quality problems not only affect the product's appearance but also reduce the protective capabilities of the metal surface, decreasing its corrosion resistance, and consequently impacting the service life and safety of elevators and other equipment.

[0011] The outlet pipe is connected to the outlet of the fine filter at one end and extends to the top of the electrophoresis tank at the other end, which is used to send the filtered electrophoresis solution back to the tank.

[0012] The drain outlets are located at the bottom of the primary filter, secondary filter and fine filter, respectively, to discharge the impurities trapped by the filter.
