Description

Technical Field

[0001] The utility model relates to the technical field of raw lacquer filtering, in particular to a two-stage raw lacquer filtering device. Background Art

[0002] Raw lacquer, commonly known as "earth lacquer", is a milky white pure natural liquid paint harvested from lacquer trees. It gradually turns brown after contact with the air. The surface dries and hardens in about 4 hours to form a paint film. Raw lacquer has high economic value. It is corrosion-resistant, wear-resistant, acid-resistant, solvent-resistant, heat-resistant, water-proof and insulating, and has good gloss. It is a high-quality paint for military industry, industrial equipment, agricultural machinery, infrastructure, handicrafts and high-end furniture. The quality grade of raw lacquer is mainly divided into four levels, of which the two-grade raw lacquer is also called mid-range raw lacquer. Its ingredients are of higher quality and can meet the decoration needs of mid-range buildings.

[0003] Since there will be some impurities in the two-stage raw lacquer, such as dust, fine hair, oil stains, etc., these impurities will affect the quality of the two-stage raw lacquer, so it needs to be filtered. By introducing the two-stage raw lacquer into the filtering device and letting the two-stage raw lacquer pass through the filter, the impurities and particles therein can be removed, making the paint cleaner and smoother, without problems such as bubbling and dripping, and at the same time, its service life can also be extended. Since the filter screens of the filtering device need to be sealed and compressed by a clamping part, and the clamping part generally needs to be driven by manually rotating the handle to compress the filter screen, it is not only time-consuming and labor-intensive but also has low work efficiency.
