Description

Technical Field

[0001] The present invention relates to the technical field of hollow fiber filtration membrane modules, and specifically to an improved sanitary hollow fiber filtration membrane module. Background Art

[0002] The hollow fiber ultrafiltration membrane module is mainly composed of two parts: hollow fibers and a membrane housing. According to different water inlet methods, the hollow fiber ultrafiltration membrane is divided into two types: internal pressure type and external pressure type. The hollow fiber ultrafiltration membrane module is a type of ultrafiltration membrane, and it is one of the most mature and advanced technologies in the ultrafiltration technology. The outer diameter of the hollow fiber is 0.5 - 2.0 nm, and the inner diameter is 0.3 - 1.4 nm. The wall of the hollow fiber is covered with micropores, and the pore size is expressed by the molecular weight of the substances that can be intercepted, and the molecular weight cut-off can reach several thousand to several hundred thousand. The raw water flows under pressure on the outside or inside of the hollow fiber, respectively constituting the external pressure type and the internal pressure type.

[0003] Currently, for the existing sanitary hollow fiber filtration membrane modules, during use, before the water enters the central control fiber membrane filaments, no preliminary filtration is carried out, which leads to a reduction in the single - use time of the central control fiber membrane filaments.

In this embodiment, the silicone ring 30 facilitates water to enter the hollow fiber membrane 29, and the hollow fiber membrane 29 filters water.

[0045] The implementation principle of this embodiment is:

[0046] Connect the input pipe to the inside of the sealing cover 9, and then inject water into the inside of the installation cylinder 1 through the input pipe. When the water enters the inside of the installation cylinder 1, it will first pass through the filter plate 12, and the filter plate 12 will filter out the larger particles in the water, and then enter the inside of the installation cylinder 1, and be injected into the inside of the hollow fiber membrane filament 29, and finally be filtered through the hollow fiber membrane filament 29. When it is necessary to replace the filter plate 12 and the hollow fiber membrane filament 29, it is necessary to swing the hook A6 to the outside. During the rotation of the hanging height A, the rotating block 5 will be inside the mounting frame 4. The hook A6 rotates 90 degrees, and the hook B8 loses its restriction. Pull the sealing cover 9 upward to separate the sealing cover 9 from the mounting tube 1. Then press the friction block 13 with your fingers and push the slide plate 11 to one side. During the movement of the slide plate 11, the ball spring lock will be disengaged from the inside of the ball groove 14. Then the slide plate 11 can be pulled out from the inside of the mounting box. When the slide plate 11 is pulled out, the filter plate 12 will also be pulled out together, and then the filter plate 12 can be cleaned or replaced.

[0047] The water filtered by the hollow fiber membrane filaments 29 will slowly seep into the interior of the installation cylinder 1 so as to flow out of the output pipeline. When connecting the output pipeline, first pass one end of the output pipeline through the fixed cylinder 24 and sleeved on the outer surface of the conical cylinder 23. Then, push the fixed cylinder 24 towards the connector 19 until the internal thread 22 contacts the external thread 20. At this time, rotate the sealing cylinder 21 and use the threaded connection to clamp the sealing cylinder 21 to the outside of the connector 19. At this time, the spring rod 25 is in a contracted state and has a certain thrust to push the fixed cylinder 24 by the sealing plate 26, so that the output pipeline can be firmly clamped on the outer surface of the conical cylinder 23. At this time, no matter how it is shaken, the connection between the output pipeline and the conical cylinder 23 will not leak water.

[0048] Compared with the prior art, the present invention has the following beneficial effects over the prior art:

[0049] Through the combined use of the mounting ring 3, the mounting bracket 4 and the rotating block 5, it plays a role in facilitating the rotation of the hook A6.

By using the above structures, larger particulate matters can be filtered out before the water enters the central control fiber membrane filaments, so as to reduce the particulate matters entering the central control fiber membrane filaments, thereby prolonging the single use time of the water entering the hollow fiber membrane filaments 29. Through the combined use of the connecting cylinder 17 and the baffle 18, it plays a role in limiting. Through the combined use of the conical cylinder 23, the connector 19 and the sealing cylinder 21, it plays a role in facilitating the clamping of the output pipeline.
