Introducing the TSQ Series: A revolutionary pneumatic scraping self-cleaning filter engineered to elevate your filtration process. This state-of-the-art filter effortlessly and automatically expels particles and impurities from the internal surface of the filter element through precise mechanical scraping. Designed to function continuously on-line, it ensures uninterrupted operation and peak performance in various conditions.
The TSQ series scraping self-cleaning filter is your ideal partner for efficiently handling high-viscosity liquids, with capabilities reaching up to an impressive 800,000 mPa.s. Offering a versatile filtration range of 25-1500μm, it excels at swiftly removing impurities by effectively scraping them off the filter element surface. Expertly crafted for both water and various viscous liquids, it ensures superior purification and cleanliness, making it indispensable for a wide array of applications.
[Filtering Status] As the liquid gracefully enters the filter, it elegantly navigates past the scraper, seamlessly flowing across the filter element from the interior to the exterior. Here, any impurities are meticulously captured on the inner surface of the element. The purified liquid then exits through the outlet. Over time, as more impurities gather, the pressure drop gently rises.
[Cleaning Status] In a harmonious cycle, the scraper descends, effortlessly guiding impurities downward. As it ascends, any remaining particles are propelled to the apex of the filter element, where they are efficiently flushed off by the flowing liquid. This process repeats as the scraper descends again, ensuring thorough impurity removal. Remarkably, the filter maintains continuous online operation throughout the cleaning phase.
[Purging Status] Following numerous cleaning cycles, impurities gradually accumulate to a significant level. By periodically opening the valve, you can efficiently purge the waste liquid, which contains a high concentration of impurities. This waste liquid can be reclaimed if desired, optimizing both cleanliness and resource recovery.
