ABSTRACT:
A centrifuge has a basket centered on and rotatable in either rotational sense about an upright basket axis. An upright and rigid support tube movable axially in the basket and pivotal between a pair of end positions carries at its lower end a fill tube from which a suspension to be filtered may be sprayed onto the inner wall of a basket. This support tube also carries at its lower end extending diametrically opposite the fill tube an arm carrying at its outer end an unloading knife. In one end position the fill tube is directed at the inner wall of the basket, so that a suspension can be sprayed on the inner walls of the basket. In the other end position the fill tube is turned away from the inner wall of the basket and the knife is juxtaposed therewith while the basket is reverse-rotated to strip off and inwardly deflect the filter cake thereon.
