ABSTRACT:
A self-discharging centrifugal drum for clarifying and separating suspensions, has an axially displaceable piston valve that is bounded above by a solids space and that opens and closes expulsion openings in the drum jacket. A closure compartment that can be charged with closure fluid and that can be evacuated through a centrifugal valve in the drum jacket is disposed below the piston valve. A second fluid-controlled centrifugal valve in the drum jacket is connected through connecting channels to the closure compartment and through a connecting channel with a reservoir in the drum jacket that is always charged with closure fluid and subjected to fluid pressure when the drum is in operation. When the closure compartment is evacuated, a valve cone in the second centrifugal valve opens to establish a connection between the closure compartment and the reservoir. This permits not only sudden evacuation but also just as sudden charging of the closure compartment with closure fluid.
