Vacuum and/or pressure filtration device for filtration of a suspension

Abstract

A vacuum and/or pressure filtration device includes a filter drum defining a drum axis and it is supported rotatably around the drum axis. The filter drum includes an outer jacket, by which a plurality of filter cells are formed, which extend along the drum axis, which are arranged adjacent to each other all around the drum axis, and which are equipped on their outer side with a filter medium; and an inner jacket, which is arranged adjacent to the outer jacket, which has an inner jacket outer surface, which limits the filter cells radially inside such that by the inner jacket outer surface a plurality of draining surfaces are formed, on which the liquid passing through the respective filter medium during filtration of the suspension can drain as a filtrate. The filtration device filters a suspension having solid and liquid components.
