Scrape Type Automatic Self Cleaning Filter For Viscosity Fluid Filtration

LABOAO scraper-type automatic self-cleaning filter is a new generation of self-cleaning filter, and its technology has reached the world's leading level. Its scraper filter is not only used for water filtration, but is also widely used for self-cleaning filtration of solvents, acid and alkali solutions, polymers, coatings and other viscous materials. It has higher efficiency, an accuracy range of 30 to 3000 microns, and can handle viscosity up to 800,000 centimeters. Boiling liquids are used in water treatment, petrochemical, metallurgy, electric power, fine chemicals, coatings, inks, papermaking, food and beverages, pharmaceuticals, metal processing and other industries.

The fully automatic self-cleaning filter automatically removes particulate impurities accumulated on the surface of the filter element through efficient mechanical scraping, and automatically removes liquid containing high-concentration impurities in the collection chamber through PLC time/pressure difference control, and discharges the residual liquid. Can be recycled or discharged. The fully automatic self-cleaning filter can continuously filter online in a single machine without manual replacement and cleaning of the filter element, and does not produce filter consumables. It is widely used in pre-filtration in the water treatment industry and self-cleaning of viscous materials such as solvents, acid and alkali solutions, polymers, and coatings. Filtration, higher efficiency, more stable and reliable performance.

Working principle: Liquid flows from the inlet of the filter, flows from top to bottom, and flows through the surface of the filter to the outlet; when a certain amount of impurities are collected on the surface of the filter, the motor drives the scraper equipped with a corrector to rotate close to the surface of the filter. The impurities are scraped off and accumulated in the collection chamber with the downward liquid. When a certain amount of impurities accumulates, the automatic drain valve opens the collection chamber to discharge the liquid containing high-concentration impurities. The residual liquid can be recycled or discharged.


1. Fully automatic online continuous filtration, reducing labor costs and meeting factory automation operation requirements;

2. No disposable discarded filter consumables are produced, saving consumable costs and environmental treatment costs;

3. The filtration pressure loss is extremely small and the flow rate is stable, which saves pipeline energy consumption and is conducive to continuous and stable process;

4. Fully enclosed filtration to prevent leakage of hazardous materials;

5. The discharged waste liquid has high impurity concentration and can be recycled to avoid the loss of high-value materials;

6. A variety of module combinations and powerful automation modes are available to meet various filtration application needs.
