Sleeve filter centrifuge
First Claim
1. Sleeve filter centrifuge comprising a drum (11) rotatably mounted in a housing (1) and having radial filtrate passages (12), an invertable filter cloth (15) covering the filtrate passages, a lid (18) closing one end face of the drum, a feed opening provided in the lid for the suspension to be filtered and a feed pipe (19) passing through the feed opening, drum and lid being axially displaceable relative to one another by means of a rotatably driven hollow shaft (3) and a support shaft (9) telescopically reciprocating therein in order to invert the filter cloth, a screw spindle (34) is arranged on the support shaft (9) and a nut (33, 36) engaging with this screw spindle is provided, and that either the screw spindle (34) or the nut (36) is rotatingly drivable by a motor (44) so that the support shaft (9) reciprocates telescopically in the hollow shaft (3) in response to the rotational speed of the screw spindle (34) or the nut (36) relative to the rotational speed of the hollow shaft (3).

Abstract
A sleeve filter centrifuge comprises a drum with radial filtrate passages (12) which is rotatably mounted in a housing (1), a sleeve filter cloth (15) which covers the filtrate passages, a lid (18) which closes the front of the drum and has a filling opening for suspensions to be filtered, and a filling pipe (19) which penetrates the filling opening. In order to turn up the filter cloth, the drum and the lid can be displaced axially relative to each other by means of a hollow shaft (3) driven in rotation and a support shaft (9) which telescopes in and out of said hollow shaft. A threaded spindle (34) is arranged on the support shaft (9) and a nut (33,36) is engaged with the threaded spindle (34). Either the threaded spindle (34) or the nut (33,36) can be driven in rotation by a motor (44) in such a manner that the support shaft (9) telescopes in and out of the hollow shaft (3) in function of the rotational speed of the threaded spindle (34) or nut relative to the rotational speed of the hollow shaft (3).
