TECHNICAL FIELD

[0001] The utility model relates to ultrafiltration equipment technical field, concretely is a novel electrophoretic liquid ultrafiltration device. BACKGROUND

[0002] In the production process of electrophoretic paint plating parts, the surface of the plated part needs to be washed with water first, and then washed with clean water once, which can clean the surface of the plated part, and then the next electroplating is carried out, so that the surface of the produced parts is smooth and beautiful. When the plated part is washed with water and pure water, wastewater containing electrophoretic paint is produced. If the wastewater is discharged into the sewer, it will pollute the environment and waste the electrophoretic paint. Therefore, the impurities in the wastewater need to be recycled, and therefore an ultrafiltration device for filtration is needed.

[0003] For example, the utility model patent with the authorization announcement number CN218435984U discloses an electrophoretic coating ultrafiltration pipe valve system and an electrophoretic ultrafiltration device.

When the ultrafiltration membrane is backwashed, the ultrafiltration work cannot be carried out, which reduces the practicability of the device and cannot meet the use requirements well.
