Abstract:
1. A centrifuge, comprising: an inlet tube; a centrifugal drum; a sieve; a distributor arranged for introducing and guiding material to be centrifuged through a passage without passing through the sieve into a solids collecting space so that during centrifugal separation a liquid component of the introduced material flows radially from the solids collecting space toward an interior of the drum through the sieve; a centrifugal chamber bounded by the centrifugal drum; the solids collecting space being, in an area of the centrifugal chamber arranged radially outside an outer circumference of the sieve; the sieve arranged in the centrifugal chamber coaxially with respect to one or both of the inlet tube and distributor; the solids collecting space being discontinuously closable so that when the solids collecting space is opened, a return flow of the liquid component takes place through the sieve from the interior of the drum; and wherein the solids collecting space is discontinuously closable by a piston slide valve.
