Abstract
The object of the invention relates to membrane housing elements that are constructed from an inner element, a fiber wrapping, and a casing, and to a method for its manufacture. Due to their structure, the membrane housing elements provide a high pressure resistance with respect to both radial and axial loading. The continuous manufacturing method allows the manufacture of a large number of piece numbers with high precision and uniformity. The membrane housing elements are used for membrane housings in the application fields of nanofiltration, ultrafiltration, ion exchange, and reverse osmosis.
Claims27
Cylindrical membrane housing element, which is constructed from an inner element, a fiber wrapping and a casing, characterized in that
- a radial wrapping made of fibers is applied to the inner element, and
- the casing, which contains at least two axial traction elements, is applied to the fiber layer.
Method for the manufacture of a cylindrical membrane housing element, which comprises at least the following steps:
- a. continuous manufacture of an inner liner that is wrapped radially with fibers,
- b. application of a casing, where the casing presents at least two deposited axial traction elements or a casing profile, into which axial traction elements can be introduced later.
Side port membrane housing element, which is constructed from an inner liner that is wrapped radially with fibers, and from an injection molded casing, characterized in that
- the inner liner is a plastic element, which is wrapped radially with fibers, and
- at least two traction elements are introduced between the injection molded casing and the fiber layer.
