Introducing our TSQ Series Pneumatic Scraping Self-Cleaning Filter - a revolutionary innovation in filtration technology! This state-of-the-art filter is engineered to effortlessly and automatically eliminate particles and impurities from the internal surface of the filter element through precise mechanical scraping. Designed for seamless, continuous on-line operation, it ensures your filtration process remains uninterrupted and efficient.
The TSQ Series Scraping Self-Cleaning Filter is expertly crafted to handle high-viscosity filtration, accommodating viscosities up to an impressive 800,000 mPa.s. With a filtration degree ranging from 25 to 1500μm, it swiftly and effectively scrapes impurities off the filter element surface, optimizing impurity removal with unmatched efficiency. This versatile filter is perfectly suited for both water and a variety of viscous liquids, making it an indispensable asset for diverse industrial applications.
[Filtering Status] As the liquid gracefully enters the filter, it journeys past the scraper, flowing seamlessly across the filter element from inside to outside. The ingenious design ensures impurities are effectively captured on the inner surface of the filter element. The now purified liquid makes its exit through the outlet. Over time, as more impurities are collected, a gentle increase in pressure drop is observed, signaling the robust performance of our system.
[Cleaning Status] The cleaning process showcases efficiency, as the scraper glides downward, gently guiding impurities to the bottom. In its upward movement, it sweeps remaining impurities to the top of the filter element, where they are elegantly flushed away by the liquid. This up-and-down motion ensures comprehensive cleaning. Remarkably, the system continues its filtration task seamlessly online, ensuring uninterrupted performance.
[Purging Status] With multiple cleaning cycles, impurities naturally gather in greater amounts. At this juncture, the valve is periodically opened to release waste liquid, rich in impurities. This process not only maintains the system's efficiency but also offers an opportunity for the recovery of valuable materials, if required, highlighting the sustainable aspect of our technology.
