Automatic Pneumatic Scraper Self-Cleaning Filter
TSQ Series Pneumatic Scraping Self-Cleaning Filter The TSQ series pneumatic scraping self-cleaning filter is an innovative marvel, designed to automatically eliminate particles and impurities from the internal surface of the filter element through a state-of-the-art mechanical scraping process. This advanced system guarantees continuous, uninterrupted online operation.
Perfectly engineered for the filtration of high-viscosity substances reaching up to an impressive 800,000 mPa.s, it offers a wide filtration degree range from 25-1500 μm. The filter's rapid impurity removal efficiency ensures that contaminants are swiftly scraped off the surface of the filter element, optimizing performance. This highly efficient filter is suitable for a variety of applications, ranging from water filtration to handling various viscous liquids.
Work Principle
Experience the sophisticated mechanics of the Pneumatic Scraping Self-Cleaning Filter for High-Pressure Water Systems. Liquid enters through the inlet, journeys through the meticulously engineered filter element, and exits with enhanced purity through the outlet. As the liquid flows, impurities find themselves captured on the inner surface of the filter element. Once these impurities accumulate to a predefined level, the innovative cleaning process springs into action, activated either by precise timer settings or a differential pressure sensor, ensuring the utmost efficiency and reliability.
In this self-cleaning marvel, a speed reducer or cylinder orchestrates the movement of scraper blades that elegantly glide along the surface of the filter element, meticulously removing impurities. These dislodged particles gracefully descend to the bottom of the filter, where a strategically placed drain valve awaits. Opened at regular intervals, this valve allows the concentrated liquid to be efficiently drained and, where applicable, reclaimed for recycling. This process exemplifies environmental consciousness and resource maximization.
