Description

Technical Field

[0001] The utility model belongs to the technical field of water-based paint filtering, in particular to a water-based paint filtering device. Background Art

[0002] Water-based paint is a commonly used material in construction and is widely used. Water-based paint refers to paints that use water as the primary dispersion medium. Depending on the dispersion form of the resin in water, water-based paints can be divided into water-soluble paints, emulsion-based paints, and water-dispersible paints. However, the processing requirements for water-based paints are relatively high. Some resins used in the formulation of water-based paints are easily hydrolyzed or sensitive to other ingredients in the formula, causing precipitation and gelation. Chemical substances in water-based paints also agglomerate, affecting the storage and performance of the paint. Therefore, filtration is essential in the processing and preparation of water-based paints.

[0003] A Chinese patent with publication number CN219502111U discloses a water-based paint filtering device, including a main body mechanism, a filtering mechanism and a connecting mechanism. The filtering mechanism is located at the inner end of the main body mechanism, and the connecting mechanism is located below the filtering mechanism. The filtering mechanism includes a filter cartridge, a driving member, a rotating rod, a knocking block, a transmission block, a slider, a spring, a slide rod and a bracket. The driving member is movably installed on the outside of the filter cartridge, and the rotating rod is fixedly installed on the transmission end of the driving member.

[0004] At present, the water-based paint filtering device in the existing technology still has certain limitations in actual use. For example, during the filtering process of water-based paint, a driving member is used to drive the knocking block so that the filter cartridge can move and filter the water-based paint. Although the effect of filtering the water-based paint can be achieved, the filter cartridge slides on the sliding rod between the internal brackets of the filtering device body through a slider, so the filter cartridge cannot be removed from the equipment for maintenance by disassembly, and maintenance must be carried out directly inside the equipment. Not only is the space narrow and maintenance is inconvenient, but it is also easy to cause problems such as incomplete cleaning. Utility Model Content
