Abstract

A self-emptying centrifuge drum has an intake for the centrifugate, a peeling chamber that accommodates a peeling disk for diverting the clarified liquid, and an automatic device that senses the level of solids in the separating space of the drum. The sensing device consists of channels extending from the separating space to another peeling chamber with another peeling disk. The outflow channel from the second peeling disk communicates with a measuring instrument that operates in conjunction with controls that introduce the extracted solids into the drum. Peeling channels are provided in the second peeling disk, extending out from its circumference and opening tangentially into an annular space that does not have any ribs and that extends radially inside the disk to detect the level of solids in the separating space even when centrifugates that do not block the channels sufficiently are being clarified.
