Principle of DY type belt press filter machine

The DY series belt press filter is mainly composed of a drive mechanism, sludge distribution mechanism, filter belt, tensioning mechanism, automatic deviation adjustment mechanism, filter belt flushing mechanism, scraping mechanism, gravity dewatering zone, wedge-shaped dewatering zone, press dewatering zone, frame, etc.

The working process is that the flocculated sludge enters the sludge distribution mechanism and first passes through the gravity dewatering zone, which is a long horizontal movement section and a small angle ascending section. The filter slurry moves along with the filter belt on the filter belt; Under the action of gravity, free water separates from flocs, removing most of the free water in the filter slurry, and the filter slurry basically loses its fluidity. Then it enters the wedge-shaped space from large to small, and finally the two filter belts are closed, gradually increasing the pressure on the filter slurry sandwiched in the middle of the filter belts, and continuously discharging water from the filter slurry. At this point, the mud has lost its fluidity and is ready for the next step of pressing and dewatering. The squeezing rollers in the squeezing and dewatering area are arranged in order of diameter from large to small, and the squeezing force on the filter slurry gradually increases from small to large. After several S-shaped pressing rolls are used to press, move, and shear the filter cake, most of the intercellular water is removed from the filter slurry, completing sludge dewatering. When the filter belt passes through the unloading mechanism, the mud cake is scraped off from the filter belt by a scraper. After cleaning and regeneration, the upper and lower filter belts return to the gravity dewatering zone to complete the next cycle of sludge dewatering.
