Abstract
A sleeve filter centrifuge comprising a drum rotatably mounted in a housing and having radial filtrate passages, an invertable filter cloth covering the filtrate passages, a cover closing one end face of the drum, a feed opening for the suspension to be filtered provided in the cover, a feed pipe passing through the feed opening, and a safety device preventing the drum being opened by the cover being detached from it for as long as the drum is rotating ar a rotational speed higher than a critical rotational speed, above which any opening of the drum would be dangerous, the drum and the cover being axially displaceable relative to one another by means of a rotatably driven hollow shaft and a support shaft telescopically reciprocating therein in order to invert the filter cloth.
