摘要： A dynamic filter system includes a dynamic filter assembly (101) including one or more filter elements (148) and one or more members (151) disposed within a housing. The filter elements and the members are interleaved and arranged to rotate with respect to one another. The dynamic filter assembly preferably includes one or more mechanisms (163, 253, 251) to prevent preferential fouling.

Date Apr. 25, 1985.A disc filter includes a plurality of rotatable, axially spaced, annular discs (9), which are adapted to be partially submerged in a liquid or suspension to be filtered. Each disc comprises a plurality of hollow filter elements (10), the interiors of which communicate with axial suction channels (13) arranged at or near the circumference of the annular discs for withdrawal of filtrate. A collecting funnel (14) is introduced through all discs (10) to receive particles or parts of filter cake falling therefrom. The axial suction channels (13) are provided with backflow barriers (15') adapted to prevent liquid flow from the suction channels (13) radially back into the filter elements when raised above the liquid surface.

Date Aug. 10, 1989.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.

Date Dec. 29, 1988.A disk filter including a plurality of rotatable, annular filter disks (3) arranged mutually spaced in an axial direction, and disposed for being partially immersed in a liquid or a suspension to be filtered. Each filter disk comprises a plurality of filter sections (4) which are in communication with axially directed filtrate conduits (2) arranged in the peripheries of the disks (3) for discharge of filtrate. The filtrate conduits (2) are provided with backwash barriers which are adapted to prevent liquid flow from the filtrate conduits radially inwards when the filter sections (4) rise above the liquid surface. The backwash barriers have been achieved by each filter section (4) being connected to an axial filtrate conduit in the form of a pipe (2), the main portion of the cross-section of the pipe at the place of attachment being located after each part of the filter section (4) as seen in the direction of rotation (A).

摘要： A rotary disk filter and a module for building a filter support for a rotary disk filter are disclosed. The rotary disk filter may comprise a drum, which is rotatable about its central longitudinal axis. The rotary disk filter may be adapted to receive a liquid which is to be filtered. In one implementation, the rotary disk filter may comprise at least one disk-shaped filter member which on the outside of the drum extends outwards in the transverse direction of the drum, and which has a filter support and at least one filter portion supported thereby. A first liquid duct may extend from the drum through the filter member and out through the filter portion. The filter portion may be made of filter segments, which are detachably secured to the filter support. At least one second liquid duct may extend between adjoining filter segments to provide liquid communication between the filter segments. The module may comprise two inner support portions and two outer support portions for at least partial enclosure of two adjoining filter segments, and an intermediate support portion adapted to be arranged between the two adjoining filter segments.
