Embodiment Construction

[0048] Detailed description of the preferred embodiment

[0049] exist figure 1 A longitudinal sectional view of an embodiment of a filter device according to the invention is shown in . figure 1 The filtering device comprises a fiber housing 1 in the form of a tube. In this case, the fiber casing 1 is produced from a flexible, watertight material over the entire length of the casing, so that it forms a flexible film surrounding the fiber bundle 2 . The fiber bundle 2 consists of a plurality of fibers extending longitudinally in the fiber housing 1 .

[0050] In the illustrated embodiment, the fibers are crimped to obtain a crimped or folded fiber bundle 2 having half the length of the non-crimped fibers. The bent end of the fiber is arranged at the outlet end 3 of the fiber housing 1 . The fibers here can be bent around a cross 4 which is fixed to the fiber housing 1 by epoxy bonding. The free end of the fiber is arranged at the inlet end 5 of the fiber housing 1 . Here...

Abstract

A device for filtering a fluid is provided, wherein said filtering device comprises a fibre housing (1) having an inlet end (5) with at least one inlet and an outlet end (3) with at least one outlet. The fibre housing surrounds and defines an outer bound for a plurality of fibres (2) extending longitudinally in the fibre housing between the inlet end and the outlet end, whereby longitudinally extending interspaces is provided between the fibres, with said interspaces defining a plurality of flow passages for the fluid. At least part of the fibre housing is formed of a flexible membrane surrounding the fibres, and compressing means (7a,7b) is provided for creating a pressure on an outer surface of the flexible membrane thereby compressing the fibres in a radial direction at least one location along the length of the fibres.

Description

background of the invention [0001] The present invention relates to apparatus and methods for filtering fluids. In particular, it relates to devices and methods for filtering fluids wherein a plurality of fibers extend longitudinally in the direction of fluid flow during filtering of said fluids. [0002] current technology [0003] US Patent No. 4,219,420 discloses a device for filtering contaminated fluid or media. According to the disclosure of this patent, a plurality of fiber bundles are positioned on a support and extend within the filter housing in a direction between the inlet and the outlet of the housing. The filtered fluid is directed through the inlet in a direction towards the outlet. The contamination particles are trapped between the fibers as they pass through the bundles of fibers. In order to improve the "depth effect" of the fiber bundle, the fibers may have different lengths. Here, the quality of the filtered fluid depends on the density of the fiber b...
