A full-jacket helix-type centrifuge including a drum and at least one weir having a port. A throttle disk is assigned to the port. At least one nozzle rotates with the drum and is assigned to an outlet for discharging clarified liquid from the drum.

Full-jacket helix centrifuge with a weir

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.

Solid-bowl centrifuge having a disk stack on the drum cover

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.
