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 comprehending the entire radius of the filter disk and at least one of the chambers contacts the respective filter bed so as to be sealed relative to it.
