[0002] Paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the object. It is usually a viscous liquid made of resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, and is prepared with organic solvents or water. During the production process of paint, impurities are usually mixed in. Before packaging the paint, it is generally filtered using a filter to ensure the purity of the paint.

[0003] Some existing devices for filtering impurities in paint production have some problems during use. For example, filtering the paint only through a filter screen results in long filtration time and low filtration efficiency. In addition, the temperature of the paint when it is discharged is often higher than the packaging temperature, and the paint cannot be cooled, thereby affecting the production efficiency of the paint.
