Abstract

Abstract A device for the filtration of fluids and comprising a container (11) provided with a lid (16) and being divided into two chambers (A,B) by means of a filter (20). The container is provided with inlet and outlet connections for the fluid and a support cage (21) for a textile filter. The object of the invention is to simplify the design and the handling upon changing of the filter and to make possible the discharge of the filtrate and the cleaning of the filter by means of flushing. These objects have been attained in that the filter element (22) is in the form of a tubular filter and the support cage (21) consists of a cylinder open at both ends, that the open ends of the tubular filter (22) are foldable around the ends (23) of the support cage, and that the folded-around portions of the tubular filter form seals, on the one hand against one of the limiting walls (19) of the chambers and on the other hand against the inner-side of the lid (16) of the container.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 143 words
A device for the filtration of fluids and comprising a container (11) provided with a lid (16) and being divided by means of a filter (20) into two chambers (A,B) provided with pipe connections (12,13) for in- and outflowing fluids, respectively, said filter (20) comprising a support cage (21) for supporting a textile filter element (22), characterized i n that the filter element (22) consists of a tubular filter and the support cage (21) of a cylinder open at both ends, that the open ends of the tubular filter (22) are foldable around the ends (23) of the support cage, and that the folded-around portions of the tubular filter form seals on the one hand against one of the limiting walls (19) of the chambers (A,B) and on the other hand against the inner side of the lid (16) of the container (11).
Claim 2
Independent Claim 143 words
A device for the filtration of fluids and comprising a container (11) provided with a lid (16) and being divided by means of a filter (20) into two chambers (A,B) provided with pipe connections (12,13) for in- and outflowing fluids, respectively, said filter (20) comprising a support cage (21) for supporting a textile filter element (22), characterized i n that the filter element (22) consists of a tubular filter and the support cage (21) of a cylinder open at both ends, that the open ends of the tubular filter (22) are foldable around the ends (23) of the support cage, and that the folded-around portions of the tubular filter form seals on the one hand against one of the limiting walls (19) of the chambers (A,B) and on the other hand against the inner side of the lid (16) of the container (11).
Claim 3
Dependent Claim 49 words
A device as claimed in claim 1, characterized i n that the support cage (21) consists of a perforated cylinder or cylinder-shaped wire cage provided, at the side facing the tubular filter (22), with a preferably fine-mesh wire mesh (27) connected to the support cage (21) at the ends.
Claim 4
Dependent Claim 37 words
A device as claimed in claim 1, characterized i n that the lid (16) is axially freely displaceable in the container opening (24) and dynamically tightend therein by the intermediary of at least one sealing member (25).
