Application of Scraper Type Self-Cleaning Filter in Paint Filtration

JX Filtration December 7, 2023 Self Cleaning Filter

The Scraper Type Self-Cleaning Filter, due to its superior performance, is highly suitable for filtering viscous liquids, including coatings. In the coating manufacturing process, impurities can still be introduced, such as mechanical impurities when adding pigments or fillers. When dispersing with sand grinding, paint slurry may contain fragmented grinding media (such as glass beads). Additionally, there may be pigment particles that are not adequately ground.

The scraper filtration equipment removes various impurities and large particles, resulting in the production of finished coatings. The main equipment for coating production includes the Scraper Type Self-Cleaning Filter, dispersion equipment, grinding equipment, paint conditioning equipment, filtering equipment, conveying equipment, etc. Commonly used equipment for color paint filtration includes vibrating screens, rotary screens, bag filters, cartridge filters, and self-cleaning filters. The selection of appropriate filtering equipment is generally based on the fineness requirements and production size of the color paint.

The Scraper Type Self-Cleaning Filter series is an ideal choice for high viscosity, abrasive, or viscous liquids, including paints. The self-cleaning filter performs self-cleaning action by mechanically scraping collected debris from the filter screen using a spring-loaded cleaning disc, cleaning the concentrated solid impurities from the medium in both strokes. The collected impurities are automatically removed from the collection chamber at the bottom of the filter.

Based on a straightforward concept, the self-cleaning filter consists of a cylindrical stainless steel housing containing a filter screen. Unfiltered liquid enters through the inlet, with solids depositing on the inner surface of the filter medium, and the filtered fluid exits through the outlet.

This self-cleaning feature provides the highest quality filtration under continuous demand without stopping production.

It's worth mentioning that using the Scraper Type Self-Cleaning Filter for coating filtration essentially eliminates manual and hazardous filter cleaning work.
