Title:
【発明の名称】液体又は分散液を濾過するフィルタ装置
Document Type and Number:
Japanese Patent JP3058773
Kind Code:
B2
Abstract:
A filtering device is described, in which a multiplicity of filter elements (1) are situated in the interior of a filter housing (7), which filter elements hang from the filter lid (3), the interior bore holes of the filter cartridges being connected to the outlet connector (6) via a channel system. At the wall of the filter housing (7) there lies a film bag (2), the top end of which is fused to an O-ring (4), which is seated in an annular groove on the flange of the filter housing, the diameters of O-ring and film bag being identical. Furthermore, between the film bag (2) and interior wall of the filter housing and in the interior of the filter cartridges are provided volume displacement bodies (16, 17, 25), which extend in axial direction over the entire length of the filter housing. When changing the filter, these volume displacement bodies are for example inflated with compressed air, as a result of which the remaining filtrate volume is considerably reduced, so that less dispersion loss occurs. The arrangement described permits the filter to be changed easily and provides advantages in the disposal of residues.
