Abstract: Filter for continuous filtration of liquids containing solids in a closed cylindrical vessel with a pressure difference between the liquid to be filtered and the filtrate, with disks which are formed by hollow filter sectors and supported at a distance from one another on a driven horizontal hollow shaft normal to the shaft, with filter beds on both sides of every filter sector and a hollow space located between the latter allowing the filtrate to flow out through the hollow shaft, and with devices which are movably pressed against on both sides of every filter disk for removing and discharging solids from the filter beds forming the outer sides of the filter disks and for cleaning these filter beds, wherein every device for removing and discharging solids from and cleaning the filter beds is formed by a closed hollow box unit which is completely surrounded by the liquid to be filtered and has a plurality of chambers which are separated from one another, wherein every chamber has at least one inlet gap compre

Abstract: Apparatus for continuously separating a solid fraction from a liquid fraction in a mixture of such fractions has a stationary cylindrical vessel which is filled with the mixture and confines a rotary carrier as well as a battery of parallel disc-shaped filters mounted on and rotating with the carrier. The filters define internal chambers for separated liquid fraction and have foraminous walls which flank the respective chambers and intercept the solid fraction. The intercepted solid fraction is removed by stationary devices having receptacles immersed in the mixture, defining internal compartments for solid fraction and carrying sealing elements which prevent penetration of mixture from the internal space of the vessel into the compartments. The separated liquid fraction is evacuated fom the vessel through a channel in the carrier, and the solid fraction is evacuated from the internal compartments by suction and/or mechanically.
