  • Patent number: 7032759
    Abstract: The invention relates to a pusher centrifuge (1) for the separation of a mixture (2) into a solid cake (3) and into a liquid phase (4). The pusher centrifuge (1) in accordance with the invention includes an outer screen drum (6) rotatable about an axis of rotation (5), a mixture distributor (7) arranged in the screen drum (6) with a pusher base apparatus (8) and an infeed device (9), with the pusher base apparatus (8) being arranged and designed such that the solid cake (3) is displaceable by means of the pusher base apparatus (8) and the mixture (2) can be introduced by the infeed device (9) via the mixture distributor (7) into an empty space (R) which arises on the displacement of the solid cake (3) by the pusher base apparatus (8).
    Type: Grant

  • Patent number: 7025211
    Abstract: The invention relates to a double pusher centrifuge including a screen drum (3) rotatable about an axis of rotation (2) for separating a mixture (4) into a solid material cake (5) and a liquid phase (6), a mixture distributor (7) arranged in the screen drum (3) and having a pusher base device (8), which is arranged to be movable to and fro along the axis of rotation (2), so that the solid material cake (5) is alternately displaceable with an outer ring zone (9). Furthermore, the double pusher centrifuge includes an infeed device (10) with which the mixture (4) can be introduced via the mixture distributor (7) into an empty space (11), which arises adjacent to the outer ring zone (9) on displacement of the solid material cake (5) by the pusher base device (8).

  • Patent number: 7017756
    Abstract: The invention relates to a multi-stage pusher centrifuge (1) for the separation of a mixture (2) into a solid cake (3) and into a liquid phase (4). The multi-stage pusher centrifuge (1) includes an outer screen drum (6) rotatable about an axis of rotation (5) and at least one screen stage (7) arranged in the outer screen drum (6), and a mixture distributor (8) arranged in the screen drum (6) with a pusher base apparatus (9), with either the screen stage (7) or the pusher base apparatus (9) being arranged movably to and fro along the axis of rotation (5) such that the solid cake (3) is displaceable by means of the pusher base apparatus (9).

  • Publication number: 20040206687
    Abstract: The invention relates to a double pusher centrifuge including a screen drum 3) rotatable about an axis of rotation (2) for separating a mixture (4) into a solid material cake (5) and a liquid phase (6), a mixture distributor (7) arranged in the screen drum (3) and having a pusher base device (8), which is arranged to be movable to and for along the axis of rotation (2), so that the solid material cake (5) is alternately displaceable with an outer ring zone (9). Furthermore, the double pusher centrifuge includes an infeed device (10) with which the mixture (4) can be introduced via the mixture distributor (7) into an empty space (11), which arises adjacent to the outer ring zone (9) on displacement of the solid material cake (5) by the pusher base device (8).

  • Publication number: 20040206686
    Abstract: The invention relates to a pusher centrifuge (1) for the separation of a mixture (2) into a solid cake (3) and into a liquid phase (4), with the pusher centrifuge (1) in accordance with the invention including an outer screen drum (6) rotatable about an axis of rotation (5) and a mixture distributor (7) arranged in the screen drum (6) with a pusher base apparatus (8). The pusher base apparatus (8) is arranged and designed such that the solid cake (3) is displaceable by means of the pusher base apparatus (8). The pusher centrifuge (1) further includes an infeed device (9) with which the mixture (2) can be introduced via the mixture distributor (7) into an empty space (R) which arises on the displacement of the solid cake (3) by the pusher base apparatus (8), with the infeed device (9) including an inlet funnel (10) which extends in a substantially divergent manner towards the pusher base device (8).
