Introducing the TSQ series pneumatic scraping self-cleaning filter, a marvel of innovation by Hebei Slot Filter Technology Co., Ltd. Engineered for excellence, this filter automatically purges particles and impurities from the interior surface of the filter element through a sophisticated mechanical scraping action. Designed for continuous, uninterrupted operation, it ensures that your system remains online at all times, offering unparalleled efficiency and reliability.
The TSQ series scraping self-cleaning filter is a pinnacle of advanced engineering, purposefully crafted to tackle even the most challenging filtration tasks. With a remarkable capacity to handle high viscosity fluids up to 800000mPa.s, and an adjustable filtration range of 25-1500μm, this filter is unmatched in its ability to swiftly remove impurities from the filter element surface. Its versatility makes it ideal for purifying water and a wide array of viscous liquids, ensuring a pristine outcome every time.
[Filtering Status] As your liquid enters the pinnacle of innovation-our filter system-it gracefully moves past the state-of-the-art scraper, channeling seamlessly from the interior to the exterior of the filter element. This journey efficiently traps impurities upon the inner surface, ensuring pristine liquid flows out through the outlet. Over time, impurities will naturally accumulate, resulting in an increased pressure drop, signaling the need for cleansing.
[Cleaning Status] In the realm of self-maintenance, our ingenious scraper mechanism takes center stage. As it descends, impurities are gently guided to the filter's bottom. During its ascent, any remaining particles are skillfully pushed to the element's top, only to be flushed away by the liquid's force. When descending again, the scraper ensures all residual impurities are meticulously removed. Remarkably, even during cleaning, our filter operates continuously online, guaranteeing an uninterrupted process.
[Purging Status] After a series of cleaning cycles, the inevitable accumulation of impurities necessitates decisive action. By periodically opening the valve, you can purge the waste liquid, which is densely packed with impurities, allowing for recovery if needed. This step ensures the filter remains at peak efficiency and prolongs its impeccable performance.
