ABSTRACT:
The invention relates to a method and a device for separating liquids and solids from a mixture, in which the mixture is applied in the form of a layer to a movable, endless filter belt, which is supported from a subjacent suction box adapted to move parallel to the belt, in which box a subatmospheric pressure is intermittently produced, the liquid constituents of the mixture being drawn across the filter belt during the periods of subatmospheric pressure, while the filter belt and the suction box are in intimate contact with each other and do not move relatively to each other owing to the suction force, whereas at the restoration of the atmospheric pressure in the suction box a relative displacement of the filter belt and the suction box is carried out.
