    Abstract: A method of separating a liquid from a liquid-laden solid material includes providing a trough having a deck defining a support surface with passages extending through the support surface. The liquid-laden solid material is deposited onto the support surface so that the liquid-laden solid material is supported by the support surface. A vibratory force is applied to the deck to separate a substantial portion of the liquid from the liquid-laden solid material. The liquid separated from the liquid-laden solid material is directed under gravity force through the passages extending through the support surface. The solid material is conveyed along the support surface by the vibratory force to a solids discharge point.

The skirt includes a flange on its distal end that engages the bucket wall. To accommodate a frustum bucket with changing wall diameter, the skirt flexes resiliently with the flange engaging the bucket wall and the skirt flexing inward as the screen is inserted in a bucket with decreasing diameter. To allow movement of the skirt, a plurality of slits extend vertically, opening at the skirt distal end, providing an effective splash shield between the skirt and the bucket wall.

  • Patent number: 6622871
    Abstract: The present invention involves a plate-shaped filter holder for use with a sterilizing container. The filter holder comprises a peripheral outer pressure rim, a central pressure region, a mounting device for fixing the filter holder on the sterilizing container and including webs between the outer pressure rim and the central pressure region which leave open breakthroughs therebetween. In order to prevent undesirable deformations in the filter holder, the webs extend at least partially in a direction which comprises a component in the peripheral direction.

  • Publication number: 20030150794
    Abstract: The invention relates to a method for the production of a discoid filtration body (filter plate), comprising two internally connected support bodies, made from porous material and which enclose filtrate drain channels between them and at least one membrane filter layer on the external side of the support body halves. The invention is characterised by the following method steps: both support body halves (3.2, 3.3) are produced by casting after the slip casting method; the casting mould (10) comprises a porous, optionally hydrophilic material; the mould cavity is shaped such that the inner contour thereof closely corresponds to the external contour of the support body (3.2, 3.3); for the production of both connected support body halves (3.2, 3.3), a first amount of suspended support body material, corresponding to a support body half (3.2), is poured into the mould; an intermediate body (3.

  • Patent number: 6595373
    Abstract: A wedge wire for use in a wire type screen for screening papermaker's stock is formed with an elongated body (12) having an enlarged head (20) at the inlet surface of the screen. The head (20) is formed with tapered walls (30, 33) that cooperate to define grooves (28) at the inlet surface between adjacent elements including an upstream wall (30) and a downstream wall (33). A radiused protuberance or projection (37) defines one wall of a screening slot (15), with a wall surface (22) of an adjacent wedge wire element. The slot wall formed by the projection (37) is free of sharp edges and is limited in length, in the direction of flow through the slot (15), not substantially exceeding the gap width of the slot. The upstream wall (30) defining the groove (28) provides protection for the slot (15) against impact and damage by contaminants that may be contained in the papermaker's stock. The slot (15) is free of sharp corners so as not to impede flow through the slot.

  • Patent number: 6589424
    Abstract: A method for making a screen cylinder is described in which screen wires are arranged on the inner surface of a support wire at certain intervals and attached by a weld from the outer surface of the support wire. In a preferred embodiment of the invention, the screen wires are arranged in mounting grooves provided on the inner surface of the support wire and welded by a welding method providing deep penetration so that the weld extends through the support wire from the outer surface of the hoop to the screen wire. In another embodiment, a welding groove is formed on the outer surface of the support wire and the weld is effected in the welding groove. The invention further relates to a screen cylinder manufactured by the method of the invention.

  • Patent number: 6582598
    Abstract: Rotary filters, known within the polymer melt filtration industry, are improved by the provision of wave shaped filter support plates within the filter chambers of a rotatable disc of a filter. This rotatable disc filter has further a series of tabs, holddowns, or projections within this invention which further prevents the wave shaped filter media which conforms to the filter support from motion relative to the filter support and thus prevents damage to seals or the housing of the filter.

  • Publication number: 20030075492
    Abstract: A laminated modular water filter includes superposed annular plates. A filter unit is disposed between each adjacent pair of the annular plates. The annular plates include a top plate, a bottom plate, a plurality of intermediate plates, and at least one flow-guiding plate sandwiched between two of the intermediate plates. Each of the top plate, the intermediate plates, and the bottom plate has an annular outer passage unit in fluid communication with a curved outer passage unit in the flow-guiding plate. Dirty water is introduced into two side openings in the top plate, and flows into central holes in the annular plates via the filter units so as to form filtered water. Solid particles in the dirty water are guided into two side openings in the bottom plate via the annular outer passage units and the curved outer passage unit.

  • Publication number: 20030047506
    Abstract: An injection molding machine includes a nozzle for supplying a melted resin into a mold. In the nozzle, there is a filter for removing foreign materials mixed in the melted resin. The filter has a cylindrically-shaped filter body. In the filter body, many small holes are formed. By supplying the melted resin into the mold, the melted resin passes through the small holes into outside of the filter body. In cleaning the filter, the melted resin flows from the outside into the inside. The small holes each are smaller on the inside than the outside.

    Abstract: A filter element assembly has at least two cylindrically shaped and concentrically arranged filter media sleeves each connected at one end thereof to an inlet plate and each connected at the other end to a closed end terminal plate. Openings are provided in the inlet plate to permit entry of liquid to be filtered into the annular space between the filter sleeves. The closed end terminal plate prevents flow of unfiltered liquid from the annular space between the sleeves so as to force the liquid through the porous media of the sleeves to effect filtration.
