摘要： The invention suggests a filter device having a stationary head piece and a movable end piece, a pack of at least a recess plate and an adjacent recess plate between the head piece and the end piece, the recess plate and/or the adjacent recess plate having a recess, that forms a filter chamber between the recess plate and the adjacent recess plate, a first filter cloth and a second filter cloth between the recess plate and the adjacent recess plate for retaining as a filter cake a solid content of a suspension, and allowing a remaining liquid fraction of the suspension to pass as a filtrate, and a suspension pipe running through the pack between the head piece and the end piece for charging the suspension through the filling shoe between the first filter cloth and the second filter cloth into the filter chamber, and a filling shoe comprising an outlet section for the suspension, clamping the first filter cloth to the recess plate during filtering operation of the filter device, an anchoring section for anchoring the filling shoe in an anchoring position to the recess plate, and a pivot section between the outlet section and the anchoring section, that tiltably connects the outlet section to the anchoring section. The invention further suggests a method for operating such filter device.

摘要： The invention relates to a ceramic filter element (22) for removal of liquid from solids containing material in a capillary suction dryer. The filter element comprises a ceramic substrate covered by a sintered ceramic microporous layer (31). The sintered microporous membrane layer is provided with coarse solid particles (71) of a particle size larger than a pore size of the membrane material layer (31) so as to form a textured surface (50) which prevents a filter cake from sliding off the surface of the filter element prior to the intended cake discharge.
