Abstract

A housing made of plastic material for hollow fiber filter modules, includes both an abutment ring close to that end thereof which will be the bottom end after the module has been mounted vertically, and a centering ring at a short distance from the opposite end.

Claims

1. An axially-extending and circumferentially-closed hollow housing made of substantially rigid material for a hollow fiber filter module, a perforated sleeve of substantially rigid material containing hollow fibers received therein, said housing including both an abutment ring disposed in the interior of said housing with an inwardly projecting horizontal section close to that end of said housing which will be the bottom end after said module has been mounted vertically, and a centering ring adjacent the opposite end of said housing, the width of said centering ring corresponding to the gap between said housing and said sleeve, said sleeve being secured within said housing by potting said sleeve, the potting resin being disposed about said abutment ring and said centering ring and penetrating said sleeve.

2. A housing according to claim 1, wherein the abutment ring has a downwardly and inwardly tapering section followed by a further inwardly projecting horizontal section.

3. A housing according to claim 1, wherein the abutment ring is integrally molded with the housing.

4. A housing according to claim 1, wherein the centering ring is an add-on part.

5. A housing according to claim 4, wherein the centering ring is square or rectangular in section.

6. A housing according to claim 1 wherein said abutment ring is continuous.

7. A housing according to claim 1 wherein said housing defines an internal wall, and said abutment ring is secured to said internal wall of said housing for supporting the end of hollow fibers joined into one or more bundles.
