Description

Technical Field

[0001] The utility model relates to the technical field of electrophoretic coating, in particular to an electrophoretic tank for electrophoretic coating. Background Art

[0002] Electrophoretic coating is a coating method that uses an external electric field to cause particles such as pigments and resins suspended in the electrophoretic liquid to migrate in a directional manner and accumulate on the surface of the base workpiece of one of the electrodes to form a paint film. This technology was first applied to automotive primers by Ford Motor Company in the 1960s. Due to its excellent anti-corrosion and anti-rust functions, it has been widely used in military, automotive, high-speed rail, engineering machinery and other industries. During the electrophoretic coating process, a certain amount of heat will be generated due to the action of the electric field and the chemical reaction of the coating. If the heat cannot be dissipated in time, it will affect the quality and efficiency of the electrophoretic coating and may even cause safety accidents. With the continuous development of electrophoretic coating technology, the requirements for the heat dissipation performance of equipment are becoming higher and higher. How to further improve the heat dissipation efficiency and reduce energy consumption while ensuring the stable operation of the equipment is the main challenge facing the current electrophoretic coating heat dissipation technology. For this reason, we propose an electrophoretic tank for electrophoretic coating. Utility Model Content

[0026] Furthermore, a condenser bracket 9 and a compressor bracket 10 are fixedly installed on the top of the electrolytic cell bracket 4 close to the condenser 2 and the refrigerant medium compressor 3, and the condenser 2 and the refrigerant medium compressor 3 are fixedly installed on the electrolytic cell bracket 4 through the condenser bracket 9 and the compressor bracket 10.

[0027] Furthermore, a condenser fan 11 is fixedly mounted on the side of the condenser 2 facing away from the electrolytic cell 1 .

[0028] Furthermore, a second vertical condenser 13 is provided on one side of the shell of the electrolytic cell 1 close to the condenser 2 and the refrigerant compressor 3, a first vertical condenser 12 is provided on the side of the shell of the electrolytic cell 1 away from the second vertical condenser 13, and a horizontal condenser 14 is provided at the bottom end of the shell of the electrolytic cell 1. The first vertical condenser 12, the second vertical condenser 13 and the horizontal condenser 14 all extend through both sides of the electrolytic cell 1 and merge together to form a condenser 7. By installing the condenser 7 inside the shell of the electrophoretic cell 1 and utilizing the circulating refrigerant medium to flow in the condenser 7, the temperature of the electrophoretic cell liquid can be reduced. This method can accurately control the temperature inside the electrophoretic cell 1 and keep the cell liquid temperature stable within a suitable range. Through efficient refrigerant medium circulation and the layout of the condenser 7, effective management of the heat generated during the electrolysis process is achieved, ensuring the stability of the temperature inside the electrolytic cell, thereby improving the efficiency and safety of the electrolysis reaction.

[0029] Furthermore, the refrigerant medium filled in the condenser tube 7 is Freon.

[0030] Furthermore, the condenser 7 extends through both ends of the refrigerant medium compressor 3, a condenser outlet 15 is fixedly installed at one end of the condenser 2 close to the refrigerant medium compressor 3, and a condenser inlet 16 is fixedly installed at one end of the condenser 2 away from the refrigerant medium compressor 3. The condenser 7 enters the interior of the condenser 2 through the condenser inlet 16, and extends out through the condenser outlet 15 to enter the interior of the refrigerant medium compressor 3.

[0031] Working principle: In the electrolytic cell 1, when the electrolysis reaction is carried out, a large amount of heat will be generated. This heat needs to be effectively dissipated to maintain the stability of the temperature inside the electrolytic cell, thereby ensuring the efficiency and safety of the electrolytic reaction; the refrigerant medium is compressed by the refrigerant medium compressor 3 to form a high-pressure refrigerant medium gas, and the high-pressure refrigerant medium gas is sent to the first vertical condenser 12, the second vertical condenser 13 and the horizontal condenser 14 inside the electrolytic cell 1 through the condenser 7. These condensers are tightly attached to the inner wall of the shell of the electrolytic cell 1, effectively The heat generated during the electrolysis process is absorbed to reduce the temperature of the refrigerant gas and liquefy it. The refrigerant liquid that has absorbed the heat flows out from the outlet of the condenser tube 7 and enters the condenser 2 through the condenser inlet 16. In the condenser 2, the outside air exchanges heat with the refrigerant through the condenser fan 11, so that the refrigerant further dissipates heat and cools down. The refrigerant after heat dissipation flows out from the condenser outlet 15 and enters the refrigerant compressor 3 again. In the compressor 3, the refrigerant is compressed again into a high-temperature and high-pressure gas, and then sent back to the electrolysis through the condenser tube 7. A new round of circulation begins in the first vertical condenser tube 12, the second vertical condenser tube 13 and the horizontal condenser tube 14 inside the electrolytic cell 1. The first filter screen 5 and the second filter screen 6 filter the impurities or sediments that may be generated during the electrolysis process inside the electrolytic cell 1 to maintain the purity of the electrolyte, thereby improving the electrolysis efficiency. By controlling the working state of the refrigerant medium compressor 3, the circulation speed and temperature of the refrigerant medium can be adjusted, thereby achieving precise control of the internal temperature of the electrolytic cell 1. The condenser 2 and the refrigerant medium compressor 3 are fixedly installed in the electrolytic cell 1 through the condenser bracket 9 and the compressor bracket 10. On the electrolysis cell bracket 4, the design of the wave plate 8 helps to improve the distribution of the electric field at the bottom of the cell, making the electric field more uniform and reducing wear and corrosion at the bottom of the cell. This helps to prevent the sediment generated during the electrophoresis process from accumulating at the bottom of the cell, keeping the cell clean and the liquid flowing smoothly. The wave shape of the wave plate 8 can increase the fluidity and mixing effect of the electrophoresis liquid. Through the efficient circulation of the refrigerant medium and the layout of the condenser tube, effective management of the heat generated during the electrolysis process is achieved, ensuring the stability of the temperature inside the electrolytic cell, thereby improving the efficiency and safety of the electrolysis reaction.
