Description

Technical Field

[0001] The utility model relates to the technical field of hollow fiber membrane components, in particular to a detachable immersed hollow fiber membrane component. Background Art

[0002] With the rapid development of my country's economy, the consumption of water resources has doubled, resulting in a shortage of water resources. At the same time, a large amount of sewage is also generated, increasing the pressure on social and environmental sustainable development. In recent years, membrane separation technology and devices have been widely used in biological, chemical, pharmaceutical, food, municipal and other sewage treatment fields. Hollow fiber membrane components are asymmetric self-supporting filter membranes that can be backwashed to maximize the benefits of cross-flow filtration. Among them, immersed hollow fiber membrane components are widely used because of their high water production, low energy consumption, and easy combination with other processes. However, during long-term use, a large amount of dust and impurities will accumulate on the hollow fiber membrane bundle, resulting in a poor filtering effect of the hollow fiber membrane bundle. In addition, traditional hollow fiber membrane bundles are fixedly installed, which is inconvenient to disassemble and clean. When the hollow fiber membrane bundle is replaced, the device needs to be replaced as a whole, resulting in a waste of resources and cannot meet people's use.

[0003] In summary, the utility model solves the existing problems by designing a detachable immersed hollow fiber membrane component. Utility Model Content

[0027] Specifically, refer to Figure 3 and Figure 4 The inner wall size of the limit groove 201 matches the outer size of the limit block 6, and the inner wall of the limit groove 201 is snap-connected with the outer part of the limit block 6, thereby ensuring that the limit blocks 6 on both sides of the installation frame 4 are synchronously connected to the inside of the limit groove 201 after the connecting block 5 at the bottom of the installation frame 4 is connected to the installation groove 101, so that the installation frame 4 is fixed on the base 1 and is located between the two support plates 2.

[0028] Furthermore, the inner wall size of the mounting groove 101 matches the outer size of the connecting block 5, and the inner wall of the mounting groove 101 is snap-fitted to the outside of the connecting block 5, thereby ensuring that the mounting frame 4 is fixed to the base 1 by connecting the connecting block 5 to the inside of the mounting groove 101, and the bottom of the mounting frame 4 will not be dispersed and displaced by the water flow.
