Filter housing for exchangeable filter

摘要

The invention relates to a filter housing for exchangeable filters, having a housing base for accommodating the filter and having a housing dome which engages over the filter, wherein the housing base and the housing dome are connected to one another by means of an aseptic clamping connection which has a groove-type clamping fitting on the housing base and has a flange-type clamping fitting on the housing dome, these being fixed against one another in their connected position by means of a clamp, wherein the groove-type clamping fitting has a seal groove with a seal by means of which the groove-type clamping fitting can be sealed off with respect to the flange-type clamping fitting, wherein the housing base has a port for the supply of liquid to be filtered and has a port for the discharge of filtered liquid, and wherein the housing base has, transversely with respect to the housing longitudinal axis, a base surface which is adjacent to the face surface of the inserted filter.

主权项

1. A filter housing (1) for exchangeable filters, having a housing base (2) for accommodating the filter and having a housing dome (3) that engages over the filter, the housing base (2) or and the housing dome (3) being connectable to one another by an aseptic clamping connection (14) that has a groove-type clamping fitting (5) on the housing base and has a flange-type clamping fitting (6) on the housing dome, the groove-type clamping fitting (5) and the flange-type clamping fitting (6) being fixed against one another in their connected position by a clamp (4), the groove-type clamping fitting (5) having inner and outer collars (23, 24) defining a seal groove (10), a seal (11) that seals the groove-type clamping fitting (5) off with respect to the flange-type clamping fitting (6) being disposed in the seal groove (10) between the inner and outer collars (23, 24), the housing base (2) having an inlet port (15) for supplying liquid to be filtered and an outlet port (18) for discharging filtered liquid, the housing base (2) further having a base surface (19) radially inward of the inner collar (23) and offset axially from the seal groove (10) and extending toward the outlet port (18), all areas of the base surface (19) between the inner collar (23) and the outlet port (18) being inclined inward toward a longitudinal axis (20) of the housing (1) with respect to a horizontal plane (25) arranged transverse to the longitudinal axis (20) of the housing (1) so that the inclined base surface (19) guides any of the liquid thereon to the outlet port (18).
