Abstract
A reverse filter centrifugal machine has a self-contained, rotatably mounted basket (7) in a housing (1), provided with radial filtrate passages (11) and capable of receiving an overpressure or a negative pressure, as well as a lid (19) that closes the free front side of the basket. The basket and the lid are axially movable with respect to one another. A feed opening for the suspension to be filtered is arranged in the lid and a feed pipe (21) is sealingly inserted through the feed opening. The feed pipe (21) is rotatably mounted around its longitudinal axis and can be rotated together with the basket (7) around this axis.
