Problems solved by technology

However, since the hollow fiber membrane is a polymer material, it does not have rigid characteristics, so it cannot be sealed by rigid thread, hoop and other connection methods.
However, in the process of encapsulating the film wire with epoxy resin glue, it takes several days for the epoxy resin to dry completely, which consumes man-hours
When the membrane is fouled or broken and cannot be used, the entire membrane module including the membrane shell, interface, etc. has to be scrapped.
The membrane shell and interface are reusable engineering materials, scrapping means waste of these materials and may cause environmental pollution

Embodiment 1

[0041] Such as figure 2 Shown is a schematic diagram of the detachable hollow fiber membrane module structure of Example 1 of the present invention, which is a monofilament membrane module structure, which is usually used in laboratories to test the filtration performance of a certain hollow fiber membrane , and various working parameters such as osmotic pressure and backwash time. Membrane shell 2 comprises two water production ports, is located at a hollow fiber membrane membrane silk 3 inside membrane shell 2, has through hole in the middle of this hollow fiber membrane membrane silk 3, and its length is greater than the length of described membrane shell 2, makes hollow The fiber membrane filaments 3 can protrude to the outside of the membrane shell 2; the two ends of the membrane shell 2 are also provided with end caps 1 . The hollow fiber membrane filament 3 is provided with a needle 4, about 1 / 2 of the length of the needle 4 is inserted into the through hole of the me...

Embodiment 2

[0047] image 3 It is a schematic structural diagram of a detachable hollow fiber membrane module in Example 2 of the present invention. The difference between embodiment 2 and embodiment 1 is that in embodiment 2, the hollow fiber membrane filaments 3 contained in the membrane case 2 are not single, but multiple. For the membrane module that needs to assemble a plurality of membrane filaments 3, the membrane assembly structure is basically the same as that of Example 1, except that before inserting the hollow fiber membrane filaments 3 into the module 2, there is another step of aligning the membrane filaments: A plurality of hollow fiber membrane filaments 3 are arranged side by side to form a membrane bundle. The cross-section of the membrane bundle is preferably the same as the shape of the port of the membrane shell 2, and then the membrane bundle is inserted into the membrane shell 2, and the two ends of the membrane bundle exposed outside the membrane shell 2. Then, t...

Abstract

A detachable hollow fiber membrane module, including hollow fiber membrane filaments, and a membrane case for installing the membrane filaments, the membrane casing is provided with a water production port; the two ends of the fiber membrane filaments are respectively inserted into A needle, and a hoop is provided on the outside of the fiber membrane silk corresponding to the position of the needle; the membrane silk is placed in the membrane shell, and the two ends of the membrane silk and the hoop are exposed on the the outside of the membrane shell; two end caps are respectively used to connect to the two ends of the membrane shell, and an inner hole is arranged in the middle of one end of the end cap; wherein, when the end cap is connected to the end of the membrane shell When it is in the middle, the inner hole wall of the end cap presses the hoop, tightens the fiber membrane filament and the needle, and the outer end of the needle passes through the end cap. The detachable hollow fiber membrane module structure of the present invention does not need to be sealed with epoxy resin, and the membrane shell and end cap can be reused to improve efficiency and reduce waste of materials.

Description

technical field [0001] The invention belongs to a hollow fiber membrane module. More specifically, the present invention relates to a detachable hollow fiber membrane module structure. Background technique [0002] Hollow fiber membrane (hollow fiber membrane) looks like a fiber. The outer diameter of the hollow fiber is 0.4-2.0mm, and the inner diameter is 0.3-1.4mm. The wall of the hollow fiber tube is covered with micropores. The types of hollow fiber membranes include mixed cellulose ester microporous membranes, nitrocellulose membranes, polyvinylidene fluoride membranes, cellulose acetate membranes, regenerated cellulose membranes, polyamide membranes, and polytetrafluoroethylene membranes. and polyvinyl chloride membranes. Hollow fiber membranes are often used for water treatment, and are used in the fields of pharmaceutical, brewing, catering, chemical industry, municipal sewage reuse, hospital, residential sewage reuse, papermaking and other production and domesti...
