[0024] In the installation process, the hollow fiber membrane 4 is folded into a U shape, the two ends of the hollow fiber membrane 4 are inserted into different threading holes 5 from the same side of the anti-winding threading plate 3, and then the fixed holes 6 corresponding to the threading holes 5 are penetrated through the lower cover plate 2 of the end cap, the hollow fiber membrane 4 is fixed on the side of the lower cover plate 2 of the end cap away from the anti-winding threading plate 3 by the fixing member, and then the upper cover plate 1 of the end cap is fixed to the side of the lower cover plate 2 of the end cap away from the anti-winding threading plate 3.

[0025] By adding the anti-winding threading plate 3 and the U-shaped hollow fiber membrane 4, the hollow fiber membrane 4 can be limited, avoiding the traditional melting welding process, thereby reducing the technical difficulty and cost in the processing process, while increasing the membrane area by about 3%, and by reducing the welding step, the processing defects and failure points can be reduced, and the overall production efficiency and product quality are improved. And through the anti-winding threading plate 3, the hollow fiber membrane 4 can be easily applied to tension, and the movement range of the hollow fiber membrane 4 during installation and use can be limited, reducing the possibility of mutual contact and entanglement between the hollow fiber membranes 4 under the condition of fluid flow or equipment vibration, and making it easier to clean the filter membrane, reducing cleaning time and manpower.

[0026] As shown in Figures 1-4 , the open ends of the hollow fiber membrane 4 are respectively penetrated through two adjacent threading holes 5 and fixed holes 6. By adjacent threading holes 5 and fixed holes 6, the installer can more easily align and fix the hollow fiber membrane 4, reducing errors and confusion during installation. The design of adjacent holes enhances the connection stability between the anti-winding threading plate 3 and the hollow fiber membrane 4, so that the hollow fiber membrane 4 can better maintain its shape and position during the filtering process, thereby improving the stability and reliability of the overall equipment.

[0027] As shown in Figure 5 , 6 , the fixing member is a cylindrical fixed terminal 8, one side of the lower cover plate 2 of the end cap and the upper cover plate 1 of the end cap abut each other and are provided with a sunken platform, the sunken platforms cooperate to form a fixed cavity 9, the threading holes 5 are in communication with the fixed cavity 9, the free ends are placed in the fixed cavity 9 and are sleeved with the fixed terminal 8, the radius difference between the fixed terminal 8 and the threading holes 5 is less than the wall thickness of the hollow fiber membrane 4 tube, and the end of the fixed terminal 8 away from the hollow fiber membrane 4 can abut against the upper cover plate 1 of the end cap.

[0028] In the installation process, the free end is placed in the sink of the lower cover plate 2 of the end cover, the fixed terminal 8 is inserted into the free end, and the difference between the radius of the fixed terminal 8 and the through-hole 5 is less than the wall thickness of the hollow fiber membrane 4 tube, which ensures that the fixed terminal 8 can be tightly sleeved on the free end of the hollow fiber membrane 4, preventing the membrane from falling off. Then the upper cover plate 1 of the end cover is fixed on the lower cover plate 2 of the end cover, and the fixed terminal 8 can be limited by the fixed cavity 9, thereby preventing the fixed terminal 8 from shaking, which helps to reduce the risk of performance degradation or damage caused by membrane vibration or displacement during filtration.

The retaining ring 10 effectively prevents the hollow fiber membrane 4 from falling off in the fixed hole 6, so that the hollow fiber membrane 4 can always be kept in the correct position, which helps to maintain high filtration efficiency and reduce performance degradation caused by improper membrane position.

[0031] A plurality of bolt holes 11 are provided on the lower cover plate 2 of the end cover, and bolts are provided on the upper cover plate 1 of the end cover, which are screwed with the bolt holes 11 one by one. During installation, only the bolts need to be inserted through the holes on the upper cover plate 1 of the end cover, and then screwed into the bolt holes 11 on the lower cover plate 2 of the end cover. The bolt connection can provide high connection strength and stability, which helps to ensure that the lower cover plate 2 and the upper cover plate 1 of the end cover are always tightly connected during filtration, preventing fluid leakage or structural failure.

[0032] A plurality of polygonal counter-connected counterbores 12 are arranged on the upper cover plate 1 of the end cover. By providing polygonal counterbores 12, the weight of the upper cover plate 1 of the end cover can be reduced without sacrificing the overall structural strength, and the upper cover plate 1 of the end cover can also be added with a unique aesthetic effect.
