ABSTRACT:
A continuous-operation centrifuge drum for concentrating suspended solids. The concentrated solids are diverted out of an outer solids space through channels into an inner chamber, whence the concentrated solids are continuously extracted. At least one vortical-outflow space is positioned between the channels and the inner chamber, with the points of which the medium enters the channels distributed around the outer demarcation of the outflow space and with the outlet from the outflow space extending from a radially outward region in the outflow space to the inner chamber. A separate vortical-outflow space is associated with each channel. Each outflow space consists of two demarcating surfaces, preferably extending in planes perpendicular to the axis of rotation of the drum, and of a surrounding wall that connects them, and extends radially to a multiple of its axial length. The points at which the medium enters the channels preferably extend in planes through the axis of rotation of the drum and the outlets from the vortical-outflow spaces are positioned away from the wall.
