Automatic Pneumatic Scraper Self-Cleaning Filter
Discover the TSQ Series Pneumatic Scraping Self-Cleaning Filter - a cutting-edge solution designed for seamless filtration performance. This remarkable filter system automatically eliminates particles and impurities from the internal surface of the filter element through precise mechanical scraping, ensuring continuous and efficient online operation. The TSQ Series Scraping Self-Cleaning Filter is engineered for high-viscosity applications, accommodating up to 800,000 mPa.s. With a filtration range spanning 25-1500μm, it swiftly and effectively scrapes impurities from the filter element surface, enhancing its impurity removal efficiency. Ideal for both water and a wide array of viscous liquids, this filter promises exceptional performance and reliability.
Work Principle
The liquid enters through the inlet, gracefully traverses the filter element, and exits through the outlet, leaving behind a trail of cleanliness. As the liquid journeys through, impurities are seamlessly captured by the inner surface of the filter element. When these impurities reach a predetermined threshold, the cleaning process is elegantly activated, either by a precision timer or a differential pressure sensor, ensuring uninterrupted filtration.
The process of impurity removal is a marvel of engineering: a speed reducer or cylinder skillfully engages the scraper blades, which are meticulously mounted on the filter element's surface. These blades rotate with precision, gently dislodging impurities that descend to the filter's base. The strategically placed drain valve at the bottom is opened at set intervals to efficiently discharge the concentrated liquid, facilitating recycling or reclamation of the waste liquid, depending on your needs.
