  • Patent number: 9216369
    Abstract: In at least one embodiment, a filter device for filtering out of solid substance from a solid-liquid-mixture where the filter device includes a bearing shaft; a rotation body attached to the bearing shaft and supported by the bearing shaft to be rotatable; a single filter cell formed on the rotation body with a filter structure attached to the rotation body for filtering out the solid substance and a connection channel formed in the rotation body that extends from a filter structure outlet side to an outlet opening formed adjacent to the bearing shaft and via which the connection channel is permanently connected with an intermediate connection channel formed in the bearing shaft; a liquid discharge line connected with or formed by the intermediate connection channel; a plurality of branch-off lines which are branched-off from the liquid discharge line; and a control device having a valve assembly.

  • Patent number: 9004289
    Abstract: In at least one embodiment, a filter device for filtering out of solid substance from a solid-liquid-mixture, including a bearing shaft extending along a rotation axis; a rotation body detachable from the bearing shaft and supported by the bearing shaft to be rotatable about the rotation axis; one or more filter cells formed on the rotation body and each includes a filter structure attached to the rotation body for filtering out the solid substance and allowing the liquid to pass from an inlet side to an outlet side, and a connection channel formed in the rotation body and that extends from the outlet side to an outlet opening which is formed on an axial side of the rotation body in a radial distance to the rotation axis; and a control device having a structural control unit for providing a connection between the respective outlet opening and a plurality of lines.

  • Patent number: 5630938
    Abstract: An evertable drum centrifuge has a housing extending along an axis, a hollow filter drum rotatable in the housing about the axis and having a front end wall formed with a fill opening centered on the axis, and a nonrotatable fill tube extending along the axis and having a back end. A fill head complementarily engageable in the fill opening is fitted in a closed position in the fill opening and a suspension to be filtered is introduced through the fill tube and fill opening into the drum. A bearing rotatably supports the fill head on the fill-tube back end and a static seal is engaged between the fill head and the fill opening.
