Pneumatic scraping self-cleaning filter, is the new high performance scraping self-cleaning filter independently developed. It automatically removes the particles and impurities from the filter element internal surface by mechanical scraping and it can continuously work on-line. Scraping self-cleaning filter is designed for filtration of high viscosity up to 800000mPa.s. The filtration degree ranges for 50-1500μm. It can scrape the impurities off the filter element surface most quickly, which makes it more efficiently removing the impurities. It is applicable for water and various viscous liquid. We are the world-leading manufacturer of this kind of filter and we offer customers the proven automatic filtration technology for viscous liquid
Working Principle
[Filtering Status]Liquid enters the filter, passes the scraper and flows across the filter element from inside to outside. The impurities are blocked on the inner element surface. The liquid flows out from the outlet. After running for a period, more and more impurities accumulate and the pressure drop increases.
[Cleaning Status]The scraper moving down, the impurities are pushed down to the bottom. The scraper moving up, the remaining impurities are pushed to the top of the filter element and then flushed off by the liquid. The scraper moving down, the impurities is scraped off again. When cleaning, the filter works on-line continously.
[Purging Status]After several cleaning cycles, the impurities accumulate more and more. Open the valve periodically and purge the waste liquid of high impurity concentration, which can be recovered if necessary.
Configuration Instructions
V- SLOT Filter Element
A design of the long slit-type mesh screen, the gap of mesh screen is a V-shape, not easy to be blocked by the impurities, maintain a stable flow in long term. The width of gap on the internal surface of mesh screen, is just the filtration precision. uniform gap, , accuracy range of 50-1500 microns.
The Scraper is scraping along with the gap direction, be suitable for conven-tional filtration requirements. Smooth inner surface, accurate roundness,good scraping effect. solid structure, durable service. Mesh screen material is 316L, excellent corrosion resistance, Some troublesome impurities can also be filtered, such as: sludge type impurities, soft caking impurities
