Introducing the TSQ series pneumatic scraping self-cleaning filter, a marvel of innovation that effortlessly eliminates particles and impurities from the internal surface of the filter element. Thanks to its advanced mechanical scraping mechanism, it ensures uninterrupted, seamless online operation, providing you with the ultimate in filtration excellence and reliability.
The TSQ series scraping self-cleaning filter is expertly crafted to handle the filtration of high-viscosity substances up to an impressive viscosity level of 800,000 mPa.s. With a versatile filtration degree range of 25-1500 μm, it excels at swiftly removing impurities from the filter element surface, elevating the efficiency of impurity removal. Ideal for applications involving both water and various viscous liquids, it stands as a testament to cutting-edge filtration technology.
[Filtering Status] Initially, liquid gracefully enters the filter, seamlessly flowing past the scraper to traverse the sophisticated filter element from the inside out. Impurities are expertly trapped on the inner surface of the element, ensuring only the purest liquid flows out through the outlet. As the system operates over time, a gradual accumulation of impurities leads to a noticeable increase in pressure drop, indicating the filter's efficiency in capturing contaminants.
[Cleaning Status] As the ingenious scraper moves downward, it effortlessly guides impurities to the bottom. On its upward journey, it skillfully pushes any remaining impurities to the top of the filter element, where they are effectively flushed away by the passing liquid. The ever-efficient downward motion of the scraper ensures a thorough re-scraping of any lingering residues. Remarkably, the filter maintains continuous, uninterrupted online operation even during the cleaning phase.
[Purging Status] After a series of meticulous cleaning cycles, impurities gradually accumulate to a significant degree. By periodically opening the valve, you can efficiently purge the waste liquid of high impurity concentration. This process not only ensures optimal filter performance but also allows for the option of recovering these impurities if deemed necessary.
