Working principle
Construction and working principle: Scraper-cleaning filters is composed of the motor reducer, cylinder, strainer, scraper system, differential pressure controller, PLC controller, electric control boxes, and the sewage valve. raw materials MEDIA through the mouth into filter, from inside to outward after filter screen space, After filtration of raw materials lower part of a top-down flow of material I. More than gap filter impurities is withholded down, Filter components running after a certain time, filter impurities gap was plugged, the differential Pressure to achieve a pre-determined value, PLC monitoring and issued instructions to the signal, Driven by the rotation scraper reducer, automatically remove dirt attachment the filter, Maintain strainer filter function, and maintain the smooth flow filter screen space. At the bottom of the filter impurities increased, as long as at the bottom of the slag discharge valve is opened , impurities will be smooth emissions, allowing the pressure system to maintain normal .the scraper of Self-cleaning scraper filters with a rational layout, curettage angle optimization, under the slowdown electrical machine driven, the scrape rotation scratch impurities into the filter scraper gap timely, a clean strainer from the trouble, and maintain raw materials Unimpeded smooth. scraper system is composed of tablets ,PTFE scraper and spring self-cleaning filters, a reasonable choice of spring pressure, minimize the wear on the filter screen.
