Embodiment Construction

[0018] The drawing shows a membrane filtration unit for liquid or gaseous media, which has a bundle or an arbitrarily arranged plurality of capillary membranes 1 open at least at one end, which are cast into a desired area in the vicinity of the ends of the membrane open ends 2. Hardened into a solid head within the sealing layer 3. As can be seen from the view, the film open end 2 protrudes on the top surface of the sealing layer 3, ie on the outside of the head. The sealing layer 3 is attached with the side of the open end 2 of the back capillary film 1 to the upwardly facing side of the spacer 4 . The spacer 4 has a layer which is penetrated by the capillary film 1 and which is impermeable, or at least substantially impermeable, to the casting material to be hardened into the sealing layer 3 . exist figure 1 In the embodiment of the invention the spacer 4 consists of a perforated plate, the holes 5 of which surround the capillary membrane substantially without gaps. Depe...

Abstract

The invention relates to a membrane filter unit for liquid or gaseous media, comprising a bundle of capillary membranes (1) which are open on at least one front surface side and which are cast in an area which is close to the end of the open membrane ends (2), in a sealing layer (3) forming a hardened head part. The open membrane ends (2) protrude on the outer side of the sealing layer (3). The sealing layer (3) is arranged on a spacer element (4) which has a layer which is penetrated by the capillary membranes (1) and which is non-permeable in relation to the casting material which hardens in order to form the sealing layer (3). The invention also relates to a method for the production of a membrane filter unit.

Description

technical field [0001] The invention relates to a membrane filter unit for liquid or gaseous media, comprising a bundle or an arbitrarily arranged plurality of capillary membranes open at least on one end face, which are poured into a desired area in the vicinity of the open ends of the membranes. Hardened into a solid head within the sealing layer, with the open film ends protruding outside the sealing layer. Background technique [0002] Capillary membranes for membrane filtration can have an outer diameter of 200 μm to about 5 mm, depending on the structure and application. To ensure proper function during membrane filtration, the capillary membrane must be poured flawlessly into the head. Next, it must be ensured that the ends of the capillary membranes are not stuck, blocked or mechanically damaged when the heads are produced as cast parts. Machining by cutting should be avoided because many film materials spall into fibers when machined. [0003] In a method known f...
