Problems solved by technology

[0002] At present, columnar membrane modules have been widely used in food industry, medical field, water purification in waterworks, sewage treatment and other fields. The bonding strength between them is low, and the membrane wire is easy to bend during the insertion process, resulting in leakage points. At the same time, the end surface of the membrane module is not smooth and flat, and the membrane wire is not straight
In addition, there are large differences in processing technology, and the existing processing methods of column membrane modules mainly have the following problems
[0003] In the process of module processing, the membrane filaments are usually loaded in a wet state, and the modules are placed horizontally. In this state, due to the influence of gravity, the uniformity of the distribution of the membrane filaments cannot be guaranteed, and it is not conducive to the relationship between the membrane filaments and The resin is completely bonded, which is prone to the problem of detachment of the resin from the membrane filament and the membrane shell
[0004] In the process of resin pouring, the membrane filament and components are placed horizontally, and the membrane filament is not dry, so that the membrane filament cannot be completely straightened, and the end surface of the membrane filament is not smooth, which is prone to leakage points and resin backflow during resin pouring, reducing product quality
[0005] When the resin is poured, the resin climbs along the outer wall of the membrane filament, making the fiber brittle, and the fiber shakes during the water treatment process, and the root of the membrane filament is easily broken, which affects the water quality of the membrane filament and the service life of the membrane module.

Embodiment 2

[0035] Embodiment 2: The structure of the membrane module in this embodiment is basically the same as that in Embodiment 1, except that the number of membrane filaments in this embodiment is 10,000, the diameter of the water inlet hole is 9 mm, and the number is 10. The filling The flexible resin is polyurethane.

[0036] Similarly, in the pouring method of this embodiment, 10 casting rods for water inlet holes are selected, and the diameter of the casting rods is 9 mm. inlet holes of the same diameter.

[0037] The membrane module and its processing method provided in this embodiment reduce the number of membrane filaments and increase the size and number of water inlet holes. The membrane module formed by casting the method of this embodiment is not easy to block the water inlet holes, and the overall filtration effect is inferior to that of the implementation. example 1.

Embodiment 3

[0038] Embodiment 3: The membrane module structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the number of membrane filaments in this embodiment is 8000, the diameter of the water inlet hole is 12 mm, and the number is 12. The filled The flexible resin is silicone resin.

[0039] Similarly, in the pouring method of this embodiment, 12 casting rods for water inlet holes are selected, and the diameter of the casting rods is 12 mm. For water inlet holes with the same diameter, the overall filtering effect is inferior to that of Example 1.

[0040] The membrane module and its processing method provided in this embodiment can further reduce the number of membrane filaments and increase the size and number of water inlet holes. The membrane module formed by casting the method of this embodiment can increase the amount of raw water inflow, ensure the inflow and outflow of raw water, and effectively reduce the Membrane contamination.
