Description

Technical Field

[0001] The utility model relates to the technical field of coating processing, in particular to a coating processing filtering device. Background Art

[0002] Paint, also known as varnish, refers to a viscous liquid that is applied to the surface of an object to be protected or decorated and can form a firmly adhered continuous film with the coated object. It is usually based on resin, oil or emulsion, with or without pigments, fillers, and corresponding additives, and is prepared with organic solvents or water. The paint has strong hiding power, film adhesion, viscosity, fineness, freeze-thaw resistance, scrub resistance, aging resistance, and alkali resistance.

[0003] Most of the existing small paint processing plants use liquid vibration devices to filter the paint to reduce foreign matter inside the paint, so as to make the paint purer. However, when the existing device is used, all the paints that need to be filtered are added at one time, and the device itself is vibrated and screened. Under this action, the paint will be gathered together, thereby affecting the filtering effect of the paint and reducing the filtering effect of the device on the paint.

[0004] At the same time, most of the existing devices are unable to clean the filter during use and can only be cleaned after filtering is completed, resulting in the filtered foreign matter being blocked in the mesh of the filter. It is easy for the foreign matter to block the mesh and the paint cannot be filtered, thereby affecting the filtering effect of the device on the paint and reducing the applicability of the device.
