Abstract
A hollow fiber type filter having a simple structure and also having an excellent heat resistance which can withstand a rapid temperature change due to high temperature generated in, for example, a steam sterilization is disclosed. The hollow fiber type filter comprises a case and a plurality of hollow fiber type filter membranes which are bundled and fixed with a potting material in the case, wherein a stop ring designed such that a thickness thereof increases inwardly is provided on an inner surface of the case into which the potting material is poured, and air release portions which penetrate the stop ring in the direction of the thickness of the stop ring is formed at an appropriate portion of the stop ring.
Claims12
A hollow fiber filter, comprising:
- a case;
- a plurality of hollow fiber membrane filters which are bundled in said case;
- a potted material fixing said hollow fiber membrane filters in the case;
- a stop ring having a thickness thereof which increases inwardly toward an inner edge of the stop ring located on an inner surface of the case into which the potting material is poured;
- and
- air release portions which penetrate the stop ring in the direction of the thickness thereof as cut off sections disposed at predetermined intervals of said stop ring.
A hollow fiber filter, comprising:
- a case;
- a plurality of hollow fiber membrane filters which are bundled in said case;
- a potting material fixing said hollow fiber membrane filters in the case;
- a stop ring having a cross section of a tapered form on an upper and lower edge portion thereof and having a thickness thereof which increases inwardly toward an inner edge of the stop ring located on an inner surface of the case into which the potting material is poured;
- and
- air release portions which penetrate the stop ring in the direction of the thickness thereof as partly cut off sections disposed at predetermined intervals of said stop ring.
A hollow fiber filter, comprising;
- a case;
- a plurality of hollow fiber membrane filters which are bundled in said case;
