Description

Technical Field

[0001] The utility model belongs to the technical field of water-based paint processing, and specifically relates to paint extraction equipment. Background Art

[0002] Water-based paint is a type of paint that uses water as a solvent. Compared with traditional solvent-based paint, water-based paint does not contain harmful volatile organic compounds, so it has less impact on the environment and human health. Water-based paint is widely used in interior decoration and home coatings, including coating of walls, furniture, floors and wood products.

[0003] Water-based paint is usually made of water-based emulsion resin, pigment, additives and water. Water-based emulsion resin is an important component of water-based paint, which can provide adhesion and durability of the paint film. The production process of water-based paint includes raw material selection, formula modulation, mixing and stirring, filtration treatment, packaging and filling.

[0004] In the existing technology, the traditional water-based paint extraction process usually includes the steps of solvent evaporation, precipitation filtration, activated carbon adsorption, etc. During the precipitation process of the water-based paint, the water-based paint is usually transferred to a filter medium, and then the impurities are separated. However, when there are too many types of impurities introduced during the raw material production process, storage and transportation links, or during the production process, it may be inconvenient to filter and precipitate the water-based paint twice or more during the treatment of the water-based paint, which may cause some impurities such as suspended matter or colloids after filtration to remain in the water-based paint. At the same time, during the precipitation and filtration process of the water-based paint, the water-based paint may accumulate in certain areas of the filter medium, thereby increasing the risk of clogging.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

Then, through the coordinated use of the bottom cover and the transfer pipe, the water-based paint after the preliminary treatment can flow to the interior of the inner filter cartridge, thereby facilitating the pretreatment effect of the water-based paint and reducing the filtering pressure of the subsequent filter medium on the water-based paint.

After the pretreated water-based paint flows into the interior of the outer filter cartridge 42 and the inner filter cartridge 43, the water-based paint can be located inside the outer filter cartridge 42 and the inner filter cartridge 43 for precipitation. At the same time, the inner filter cartridge 43 and the outer filter cartridge 42 filter the water-based paint from the inside to the outside in turn. After the motor 7 is running, the outer filter cartridge 42 and the inner filter cartridge 43 rotate accordingly, increasing the contact area between the water-based paint and the filter medium, thereby improving the filtration efficiency and preventing the water-based paint from gathering in certain areas during the filtration process.
