ABSTRACT:
A centrifuge, comprising a distributor for introducing material to be centrifuged and a sieve system having a plurality of axially mutually offset membrane plates, the membrane plates being arranged radially with respect to the distributor and having at least two axially-spaced membrane disks. The sieve system is arranged such that a flow directions of material to be centrifuged emerging from the distributor and a flow direction of particles deposited on the membrane plates are identical. Alos included is centrifugal drum having a centrifugal compartment with the sieve system arranged therein and a piston slide valve for closing the centrifugal drum. The invention is also a method for cleaning the centrifuge, the steps comprising: opening a piston slide valve, thereby allowing a return flow of liquid through the sieeve system; and removeing one or more of substances baked to the sieve system and impurities from the sieve system.
