Filtering device for coating

Abstract

The invention provides a filtering device for a coating. The filtering device comprises a filter body and a filter cover, wherein the filter body comprises a main shaft, filtering modules and filter screens; the filtering modules are concentrically arranged in the filter body; the interior of each filtering module is provided with a matching filter screen; each filtering screen is uniformly provided with a plurality of through holes; the upper end of the filter body is provided with a feeding inlet which is communicated with the inner chamber of the filter body; the feeding inlet is connected with a stirrer connecting pipe through a valve; and the lower end of the filter body is provided with a discharge outlet and an electric heating pipe which is communicated with the interlayer of the filter body. The filtering device provided by the invention rapidly moves under the driving of spiral blades and clean materials on the inner wall of the filter body at any time through filtering via the filter screens and rotation of scraper blades under the driving of a wall scraping unit, so the materials are substantially prevented from adhering to the wall and the efficiency and quality of filtering are improved; the filtering device is heated through the heating pipe, so the coating can be kept at a high temperature, and is not easy to form large caked blocks; and filtering is carried out in virtue of the filter screens, so filtering effect can be effectively improved, and blockage hardly occurs.

Description

technical field [0001] The invention belongs to the technical field of paint processing and production, and in particular relates to paint filtering equipment. 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 labor-inte...
