Pressure filter with a tubular, flexible and reversible filtering component

摘要

Pressure filter in which the filtering component consists of a tubular fabric (22) which can be reversed in the manner of a sock. A tubular membrane (21) which is closed at opposite ends, inflatable and resiliently deformable radially, is supported co-axially in the said filtering component. By means of this membrane (21) the layer of solid substance held on the filter, after filtering silt or the like, can be squeezed thoroughly. <IMAGE>
