Introducing the TSQ series pneumatic scraping self-cleaning filter, a cutting-edge solution designed for seamless impurity removal. This innovative filter automatically eliminates particles and impurities from the filter element's internal surface through advanced mechanical scraping. Engineered for continuous online operation, this product ensures that your filtration processes are never interrupted, providing consistent and reliable performance.
The TSQ series scraping self-cleaning filter stands out with its remarkable ability to handle high-viscosity liquids, accommodating levels up to an impressive 800,000mPa.s. With a versatile filtration degree range of 25-1500μm, it excels in quickly removing impurities from the filter element surface, optimizing efficiency in impurity removal. Perfect for both water and a variety of viscous liquids, it represents the ideal solution for maintaining purity and performance in demanding filtration applications.
[Filtering Status] As the liquid graces its way into the innovative filter, it elegantly navigates past the meticulously designed scraper, transitioning seamlessly across the filter element from its internal chamber to the exterior. Here, resilient impurities are captured with precision on the inner surface, ensuring only the purest liquid exits through the strategically positioned outlet. Over time, as impurities gather, the pressure drop gently escalates, signaling the need for enhanced filtration.
[Cleaning Status] In a ballet of motion, the scraper descends gracefully, pushing impurities downward towards the filter's base. Upon its ascent, a sweeping movement directs residual impurities upward to the pinnacle of the filter element, where they are effortlessly dislodged by the fluid's force. With each downward glide, the scraper methodically removes any remaining debris. Remarkably, during this entire process, the filter maintains continuous, online operation, ensuring unrivaled efficiency.
[Purging Status] Following a series of meticulous cleaning cycles, impurities begin to accumulate significantly. At this juncture, opening the valve at regular intervals allows for the purging of waste liquid, now rich in impurity concentration. Should there be a need, this can be expertly recovered, reflecting our commitment to sustainability and resource conservation.
