Introducing the innovative TSQ series pneumatic scraping self-cleaning filter from Hebei Slot Filter Technology Co., Ltd. This remarkable filter automatically expels particles and impurities from the internal surface of the filter element through advanced mechanical scraping, ensuring an uninterrupted online operation and setting a new standard for efficiency.
The TSQ series scraping self-cleaning filter is meticulously engineered to tackle the challenges of high-viscosity fluids, accommodating viscosities up to an impressive 800,000 mPa.s. With a versatile filtration range of 25-1500μm, this filter rapidly clears impurities off the filter element surface, epitomizing efficiency and reliability. Ideal for use in water and a variety of viscous liquids, this filter embodies the pinnacle of industrial filtration solutions.
[Filtering Status] Experience the seamless flow of liquid as it enters the filter, elegantly passing the scraper to journey across the filter element from the inside out. As it flows, impurities are gracefully captured on the inner surface of the filter element, ensuring only the purest liquid continues its voyage outward from the outlet. Over time, a natural accumulation of impurities occurs, leading to a gradual increase in pressure drop, marking the system's efficiency in action.
[Cleaning Status] Witness the precision of our design as the scraper moves downward, expertly guiding impurities to the bottom. On its upward ascent, it pushes remaining impurities to the top of the filter element, where they are effortlessly flushed away by the liquid. As the scraper descends once more, any lingering impurities are meticulously removed. This is all achieved while the filter maintains continuous on-line operation, embodying a commitment to uninterrupted performance.
[Purging Status] With the passage of several cleaning cycles, impurities gather in greater amounts. Rest assured, by periodically opening the valve, the waste liquid, now rich in impurity concentration, is purged efficiently. This waste can be conveniently recovered if necessary, showcasing our dedication to resource efficiency and sustainability.
