Working Principle
[ Filtering Status ]
Liquid enters the filter from the inlet. The spring-loaded disc-shape scraper tightly fits the filter element internal surface and stops at the top of the filter element. The liquid 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. Clean the filter element by the preset differential pressure or the preset time cycle.

[ Cleaning Status ]
The cylinder drives the scraper moving up and down and cleaning the filter element. When the scraper moving down, the impurities are pushed down to the filter bottom, and gravity particles settle down to the impurity collection chamber. When the scraper moving up, the remaining impurities are pushed to the top of the filter element and then flushed off by the liquid. The impurities pass the scraper, get back the filter element internal surface and then scraped off when the scraper moving down. Each cleaning cycle consists of several strokes. After cleaning, the filter element are regenerated. When cleaning, it filters normally and flowrate is not interrupted.

[ 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.

Applications:
■ Applicable Industries: petro-chemical, fine chemical, pulp and paper, food and beverage, water treatment, etc.
■ Applicable Liquid Types: wax, coal oil, monomer, polymer, citric acid, fermented broth, cosmetics, silicon solution, soap, sorbitol, steriodsugar, wet end additives, adhesives, inks, lubricating oils, coatings, resin, rubber, ethanol, miscella, edible oil, juice, diesel, etc.
TECHNICAL FEATURES AND ADVANTAGES
■Up-and-down reciprocating scraping, scrape impurities off directly, especially good at viscous liquid filtration and removing viscous suspending impurities
■Simple structure, easy disassembly, pull the filter element out easily after removing the scraper, easy for internal cleaning
■Automatic operation, continuously on-line filtration, terminate the hard work of filter element replacement and cleaning
■No disposable filter media, save the cost of filter media consumption and the environment treatment
■Very low filtration pressure drop, steady flow rate, save the energy, good for keeping the process continuous and steady
■Closed filtration, prevent danger of liquid leakage, good for safety production and operator’s health
