Description

Technical Field

[0001] The utility model relates to the technical field of paints, in particular to a water-based paint filtering device that is convenient for removing impurities. Background Art

[0002] Water-based paint is a kind of paint that uses water as a dispersion medium. It is mainly composed of emulsion or water-soluble resin, pigments, fillers and additives. In the production process of water-based paint, the filtration and purification of raw materials is a crucial link. Due to the viscous nature of water-based paint, it is easy for the paint to block the filter screen during the filtration process. The accumulation of large particles on the filter screen will seriously affect the speed of the water-based paint passing through the filter screen, thereby reducing the filtration efficiency.

[0003] The existing water-based paint filtering device, as described in the Chinese patent application with publication number CN217887145U, includes two layers of filter screens, the upper filter screen is used to filter impurities with larger particles, and impurities with smaller particle sizes and viscous water-based paint mucus fall into the lower filter screen through the mesh holes to avoid the mesh holes being blocked by large particles and small particles when the single-layer filter screen is filtering simultaneously, thereby reducing the filtration efficiency.

[0004] However, after long-term use, the existing filter device will accumulate a lot of impurities. When removing the impurities, the entire double-layer filter needs to be taken out, which is inconvenient to operate. Utility Model Content
