ABSTRACT:
A continuously operating centrifuge drum for concentrating suspended solids. The solids that precipitate in a stack of disks accumulate in a solids space and are diverted into a receiving chamber through mouthpieces. The mouthpieces contain throttle bores and communicate with the periphery of the solids space. To improve the known centrifuge drum to the extent that an optimal solids concentration can be obtained at low expense with no detriment to the clarified phase, there are secondary mouthpieces that also contain throttle bores, that communicate with a radially inner zone of the solids space, and that another receiving chamber is associated with. Since the volume of solids that can be diverted through the primary mouthpieces is less than the volume of solids separated in the drum, the solids flow out of the primary mouthpieces at the maximum attainable concentration, whereas the excess solids flow out through the secondary mouthpieces.
