  • Patent number: 10252277
    Abstract: A solid-bowl screw centrifuge includes one or more discharge weir(s) for discharging clarified liquid out of a drum which has a rotational axis and a rotational direction. The centrifuge has one or more through-opening(s) in a drum cover, each of which is associated with a weir plate having a recess. An open discharge channel is formed on the through-opening at the recess, a deflection from a direction parallel to the rotational direction of the drum substantially into a circumferential direction in the rotational direction being carried out by the discharge channel. The discharge channel is designed such that exiting liquid is conducted over the base of the discharge channel to an overflow edge. The base of the discharge channel to the overflow edge is inclined inwards in the rotational direction relative to the tangential direction by an inclination angle ??0 at the point of the overflow edge.

  • Patent number: 9333514
    Abstract: A solid-wall screw centrifuge includes a discharge for discharging a clarified liquid from a drum of the centrifuge. The drum includes a passage in a drum cover associated with a weir plate. The passage, drum cover, and weir plate form an overflow weir on a radial inner edge. A deflecting device is arranged on an outside on the drum cover, the deflecting device is arranged such that an exiting fluid flow from the centrifuge is one of deflected in the circumferential direction and subjected to a twist in the circumferential direction.

  • Patent number: 8465405
    Abstract: A solid-bowl centrifuge that includes a drum rotatable about a horizontal axis of rotation and a screw arranged in the drum. Also included are a continuous solids discharge located at a first end of the drum and a continuous liquid discharge located at a second, opposite end of the drum. Further included is at least one discontinuously acting outlet opening including a closure device.

  • Patent number: 7753834
    Abstract: A solid-bowl centrifuge comprising, a centrifugal drum rotatable about a horizontal axis of rotation, the centrifugal drum including a weir to drain a liquid out of the centrifugal drum, the weir including a passage having at least one passage opening in an axial end region of the centrifugal drum that includes a drum lid: a deflector plate arranged outside the centrifugal drum and in front of the drum lid, the deflector plate being stationary during an operation of the centrifugal drum and widening at least in sections as the deflector plate extends away from the centrifugal drum: and the deflector plate including an interior jacket, and a distance of the interior jacket from the horizontal axis of rotation not being constant but widening.

  • Patent number: 7083565
    Abstract: The present invention is a solid-bowl screw centrifuge that includes a centrifugal drum. The drum has a drum casing and a screw with a screw body that is surrounded by a screw blade. The screw blade forms at least one screw spiral with a conveying path for transporting material to be centrifuged. The centrifuge also includes an inlet into the centrifugal drum, at least one solid matter discharge and at least one liquid outlet. The centrifuge includes a drum chamber that is axially closed by a drum cover having essentially a conical shape. Further included is a disk stack having at least one conical disk, and the disk stack is mounted to the drum cover directly upstream of the liquid outlet. At least a portion of the disk stack is arranged in a cylindrical section of the drum chamber that has an essentially constant diameter. A screw disk is arranged on the screw body between the drum cover and a first screw spiral.

  • Patent number: 7060019
    Abstract: The present invention relates to solid bowl screw centrifuge comprising a centrifuging chamber having a rotatable screw with a center axis and a rotatable drum surrounding the centrifuging chamber. Also included is an axially extending inflow tube for guiding material to be centrifuged into a distributor. The distributor is oriented in a substantially perpendicular manner with respect to the center axis of the screw and configured for introducing the material to be centrifuged into the centrifuging chamber. The distributor further includes at least one wall having a surface structure that includes projections configured such that a substantial portion of the material to be centrifuged flowing through the distributor must flow around at least one of the projections.
