Introducing the TSQ Series Pneumatic Scraping Self-Cleaning Filter - a pinnacle of innovation that redefines efficiency in filtration technology. This revolutionary filter system expertly orchestrates the automatic removal of particles and impurities from the filter element's internal surface through a sophisticated mechanical scraping mechanism. Embrace continuous, seamless operation as this cutting-edge filter effortlessly maintains optimal performance online, minimizing downtime and maximizing productivity.
The TSQ Series Scraping Self-Cleaning Filter is meticulously engineered to tackle the challenges of filtering high-viscosity liquids, boasting a formidable capacity to manage viscosities up to 800,000 mPa.s. With a versatile filtration degree ranging from 25 to 1500 μm, this advanced filtering solution swiftly eradicates impurities from the filter element surface, enhancing efficiency and effectiveness. Ideally suited for both water and a diverse array of viscous liquids, the TSQ Series stands as the ultimate choice for superior filtration performance.
[Filtering Status] As the liquid gracefully enters the filter, it seamlessly passes the innovative scraper, elegantly flowing across the filter element from inside to outside. Impurities are skillfully blocked on the inner element surface, while the pristine liquid exits through the outlet. Over time, as more impurities gather, the pressure drop inevitably increases.
[Cleaning Status] The meticulous scraper descends, gently guiding impurities to the bottom. As it ascends, remaining impurities are effortlessly driven to the top of the filter element, where they are skillfully flushed off by the liquid. The downward movement once again ensures impurities are thoroughly scraped off. Remarkably, the filter operates continuously online during the cleaning process, maintaining peak efficiency.
[Purging Status] After numerous cleaning cycles, impurities gradually accumulate. Strategically open the valve periodically to purge the waste liquid, which is of high impurity concentration. This waste liquid can be recovered if needed, ensuring no valuable material goes to waste.
