Abstract: A rotary filter for filtering water out of water containing raw material such as fish guts and muds including a screw drum having a number of filtering holes formed therein and a screw having a shaft and a spiral vane secured to the outer surface of the shaft, in which the screen drum is arranged rotatably, the screw is arranged within the screen drum rotatably relative to the screen drum, and the screen drum and the screw are rotated by means of separate driving sources independently from each other. A period of time during which the water containing raw material is remained within the screen drum can be adjusted at will regardless of the rotation speed of the screen drum. Therefore, the screen drum can be rotated at a high speed while the raw material can remained within the screen drum for a long time period, so that the water filtering efficiency can be increased.

Abstract: A method and apparatus for doctoring (cutting) the solids off a precoat filter. A stationary doctor blade continuously doctors mud (from a mud bath) from the surface of a rotating porous surface vacuum drum. A traveling doctor blade, located upstream of the stationary doctor blade, moves back and forth along the drum. The stationary blade extends the width of the rotating vacuum drum while the traveling blade is shorter and is also located nearer to the drum surface.

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 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.

Abstract: A particle discharge mechanism is described for use on a centrifugal dewatering system, which is of relatively simple and rugged construction. The discharge mechanism includes a pair of concentric ring-like gates (50, 52 in FIG. 2) that can move across a particle discharge passageway (46) extending around a rotating vessel (14). The gates are operated in a sequence to first trap a mass of particles inside the radially outermost gate (52), to close an innermost gate (50) to isolate the trapped particles, and then to open the outermost gate (52) to release the trapped mass. In one procedure, the outermost gate is opened only slightly prior to complete particle release, to remove small amounts of remaining water in the mass of particles.

Abstract: A method and device for filtering a suspension (14), for example of yeast or other plant cell material, on a rotary vacuum filter (10), beneath which a trough (4) containing the suspension (14) is located. In order to improve the balance between dipping zone and drying zone, according to the invention a take-off knife (1) for taking off the filter cake (8) resulting from the filtering is attached to the trough (4). The level of the suspension (14) is maintained constant, and the trough (4) is moved by means of a feeding device (7) to the center of the drum (12) of the vacuum filter (10) while the drum is rotating.
