Filter used for producing nano-coating

Abstract

The invention provides a filter used for producing a nano-coating. The filter comprises a filter body and a filter cover, the filter body includes a main shaft, a filtering module and a filter screen, the filtering module is concentrically and detachably arranged in the filter body, the cooperating filter screen is arranged in the filtering module, the filter screen is uniformly provided with a plurality of through holes, and a feeding opening communicating with the inner chamber of the filter body is arranged at the upper end of the filter cover; and a discharging opening and an electric heating tube communicating with the interlayer of the filter body are arranged at the lower end of the filter body. The nano-material rapidly moves under the driving of helical blades, and is filtered by the filter screen, and a wall scraping device drives a scraper to rotate in order to momentarily clean the material on the inner wall of the filter body, so adherence to the wall is reduced, and the filtering efficiency and the filtering quality are improved; and the heating tube is used to heat in order to make the coating keep a high temperature and not form large blocks, and then the heated material is filtered by the filter screen, so the filtering effect is effectively enhanced, and the obstruction phenomenon is less likely to occur.

Description

technical field [0001] The invention belongs to the technical field of paint processing and production, and in particular relates to a filter for producing nano paint. Background technique [0002] Coating is a material that can be coated on the surface of an object by different construction techniques to form a solid film with strong adhesion, certain strength and continuity. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. Filtration is an important step in the paint production process. Impurities and particles are removed by filtration. The main tool used in the filtration process is a filter sieve, which is a simple sieve with a filter mesh at the bottom. When this type of equipment is used, the paint to be filtered is injected into the sieve, and the paint is filtered out from the filter screen by manual stirring. Although this kind of equipment can complete the filtration, the manual stirring is inefficient and la...
