Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electrophoretic paint recovery, and particularly relates to an electrophoretic paint recovery device applied to an electrophoretic coating system. BACKGROUND

[0002] The electrophoretic paint recovery ultrafiltration technology is to separate the substances through the micro-porous structure of the membrane surface. When the liquid mixture flows through the membrane surface under a certain pressure, the small molecule solute permeates the membrane (called ultrafiltrate), and the large molecule substances are intercepted, so that the concentration of the large molecules in the original liquid gradually increases (called concentrated liquid), thereby realizing the separation, concentration and purification of the large and small molecules. That is, the electrophoretic paint is filtered through the ultrafiltration membrane, the high molecular resin molecules and color particles are intercepted, and the water and small molecule substances permeate the separation membrane, thereby achieving the effects of purifying the electrophoretic paint, removing the water and recovering.

[0003] After searching, an electrophoretic paint recovery device for electrophoretic coating (publication number: CN222557107U) is disclosed in the prior art. It is recorded in the document that "the support leg is provided with an outer tank body above, the inner tank body is arranged in the outer tank body, the outer tank body and the inner tank body are coaxially arranged, the motor is arranged on the upper middle part of the outer tank body, the rotating shaft of the motor penetrates the outer tank body and is fixedly connected with the stirring rod, a plurality of stirring blades arranged in matrix are arranged on the stirring rod, the outer tank body is provided with a material guide groove at the lower end, the inner tank body is provided with a filter plate at the lower end, the filter plate is provided with a filter membrane below, the outer tank body is provided with a liquid outlet pipe at one side of the upper end, the liquid outlet pipe is provided with a liquid inlet pipe at the lower end, and the outer tank body is provided with a feeding port at one side above the motor." The cavity is formed between the outer tank body and the inner tank body of the device, the cooling liquid inside the cavity can cool the electrophoretic paint inside the inner tank body, and the phenomenon of too fast volatilization of the electrophoretic paint is avoided. The motor drives the stirring rod to rotate, and the stirring blades also rotate through the transmission of the stirring rod. The rotating stirring blades can stir the cooling liquid inside the inner tank body, effectively increasing the uniformity of the electrophoretic paint inside the inner tank body. However, the device lacks a corresponding cleaning structure, so that the filter plate is easily blocked by impurities in the liquid to be treated, thereby reducing the recovery efficiency of the device for the electrophoretic paint. Moreover, the filter membrane of the device is located inside the outer tank body, so that the cleaning and replacement process of the filter membrane is relatively troublesome, thereby consuming a lot of time, and thus reducing the efficiency of the device for recovering the electrophoretic paint.
