What are the characteristics of the design of the wiper-type self-cleaning filter?

SGG wiper type self-cleaning filter is widely used in the filtration of high solid content, fibrous impurities and higher viscosity fluids. Precision filtration (30-1500 microns) for various liquids, such as water, solvents, acids and lyes, coolants, polymers, can handle liquids with viscosities up to 800,000 centipoise. SGG wiper self-cleaning filter is used in petrochemical, metallurgy, electric power, fine chemicals, coatings, paper, food, lye, pharmaceutical, metal processing and other industries.

The raw material of the SGG scraping self-cleaning filter enters the filter through the feed port, and is filtered through the filter gap from the inside to the outside. The filtered raw material flows from the top to the bottom to the lower discharge port, which is larger than the impurities between the filters. After being cut off, after the filter is set up for a certain period of time, the filter gap is blocked by impurities. When the pressure difference reaches the preset value, the PLC detects the signal and issues a command. The speed reducer drives the rotary scraper, and the automatic cleaning is attached. The dirt on the filter screen keeps the filter function of the filter and the gap of the filter is smooth; when the impurities at the bottom of the filter increase, the slag discharge valve at the bottom is opened, and the impurities are discharged smoothly, so that the system pressure remains normal. The layout of the filter scraper is reasonable, and the scraping of the horny is optimized. Under the driving of the geared motor, the rotating scraper hangs the impurities in the filter gap in time, eliminating the trouble of disassembling the filter and keeping the raw material unobstructed.

SGG wiper self-cleaning filter design features

1. Adopt automatic online continuous filtration to meet the requirements of process automation operation;

2. The system adopts electric drive: the rotary wiper cleaning system is driven by the reducer to automatically remove the impurities attached to the filter net and maintain the filter function of the filter;

3. PLC control function: differential pressure cleaning, timed cleaning, manual cleaning;

4. After actual verification, the filtering effect is particularly good. The filter screen adopts stainless steel wedge type filter screen, which is clean and not easy to wear.
