Abstract: A filter for thickening fiber suspensions or other liquids containing solid material includes a plurality of rotatable filter disks (3) mutually spaced in axial direction and adapted to be partially submerged in a liquid (5) to be filtered. Each filter disk includes a plurality of filter sectors (4) communicating with axial filtrate discharge ducts (2) at the outer peripheries of the filter disks (3) for removal of filtrate. The axial filtrate discharge ducts (2) are open to atmosphere at at least one end (2') thereof for the purpose of conducting air through these ducts into the interior of the filter sections to replace filtrate flowing out. Advantageously, there is communication between all axial filtrate discharge ducts through annular filter disk holders (1) carrying the filter sectors (4) of the filter disks.

Abstract: A filter sector for a filter disk of a rotating filter. The filter sector includes two interconnected plate shaped elements formed from a sheet material having a relatively thin thickness and each having planar portions defining a main plane. Protrusions shaped in the material of the plate shaped elements extend outwardly from the respective main plane and are adapted to keep a filter cloth at a distance from the respective main plane. Continuous, mutually spaced, parallel ridges are shaped in the material of the plate shaped elements and extend in a first direction over the filter sector. The protrusions extend in a second direction substantially perpendicular to the first direction and each protrusion is spanning over at least two adjacent ridges. Laterally adjacent protrusions are lengthwise displaced in relation to each other by at least the spacing between adjacent ridges. The ridges have a height over the main plane that is less than the distance, and the plate shaped elements are adjoined in the main plate planes.

Abstract: A filter to concentrating fiber suspension of the type having annular filter discs (2) which rotate about a collection trough (13) for dewatered fibers. Each filter disc comprises two mutually spaced filter elements (3) which, together with an annular wall (4) radially inwardly terminating the disc, define a filtrate chamber (5) inside the disc. The filtrate chamber (5) communicates radially outwardly with its surroundings. The suspension container (1) of the filter is inwardly provided under the suspension surface with an arcuate duct (15) for each disc, this duct being in communication with the filtrate outlet (17) of the container. Thee is communication between each disc (2) and associated duct (15) such that the filtrate can be transferred from a filtrate chamber to the respective duct (15).
