Abstract
A centrifuge with a slide-in filter comprises a centrifuge basket, a filter cloth element which can be pushed into or out of it, and a machine housing, to which a first housing chamber with an outlet for discharging a filtrate and a second housing chamber with an outlet for discharging a filter cake are connected in the region of the centrifuge basket. The first housing chamber is sealingly enclosed by a first separate housing section and the second housing chamber is likewise sealingly enclosed by a second separate housing section. The two housing sections are mounted so that each is able to pivot in different directions around separate axes in such a way that they are pivotable individually between a closed state and an open state relative to the centrifuge basket.
