The invention relates to continuous deep
dewatering equipment. The equipment is mainly applied to situations, needing
solid-liquid separation, such as
sewage treatment plants, paper mills, chemical plants and pharmaceutical factories and particularly applied to continuous deep
dewatering for
sludge. The equipment is mainly composed of a distribution area, a pre-pressing area, a squeezing area anda discharging area, the distribution area comprises a
distributor and an
evening roller, and the pre-pressing area is composed of an upper filter screen, a lower filter screen and a
dewatering roller;the squeezing area is composed of an upper filter screen, a lower filter screen, an upper liner band, a lower liner band and a pressurization
assembly which are operated circularly, the upper and lower filter screens and the upper and lower liner bands overlap in the squeezing area to form a squeezing face similar to a plane, and the pressurization
assembly vertically acts on the liner bands andprovides squeezing pressure of 10-60 kilograms; the discharging area is composed of discharging rollers and scrapers, and a mud cake is continuously and automatically discharged under the function ofthe filter screens and the scrapers. After squeezing, the
water content of the mud cake is lower than 50%, and the equipment is automatically and continuously operated.
