Description

Technical Field

[0001] The utility model belongs to the technical field of degassing membranes, in particular to a membrane degassing device for pure water. Background Art

[0002] The degassing membrane contains a large number of hollow fibers, and there are tiny holes on the walls of the fibers. Water molecules cannot pass through these small holes, but gas molecules can. When working, water flows through the inside of the hollow fibers under a certain pressure, and the outside of the hollow fibers continuously extracts the gas under the action of the vacuum pump, forming a certain negative pressure, so that the gas in the water continuously overflows from the water through the hollow fibers, thereby achieving the purpose of removing the gas in the water.

[0003] Patent No. CN219409335U discloses a membrane degassing process for preparing ultrapure water equipment, which uses an electromagnetic valve to control the flow and an active switching device to improve the smoothness of the equipment operation. After working for a certain period of time, the efficiency of the membrane degasser will decrease to a certain extent, affecting the smoothness of the water output. At this time, the electromagnetic valve starts to close the flow and the power motor starts to drive the clamping cylinder to rotate to replace the membrane degasser, so that the preparation efficiency of ultrapure water is stable and continuous. The water entering the equipment through the water inlet pipe is pressurized by a booster pump and then enters the filtration module through a connecting pipe for ultrapure water filtration step processing. Reasonable pressurization treatment can improve the efficiency of water output and ensure the continuity of equipment operation.

[0004] In the current existing technology, the membrane degasser is placed in a clamping cylinder. After being clamped by the clamping cylinder, water flows through the membrane degasser, thereby utilizing the membrane degasser to separate the gas in the water. During the separation process, the flow of water will drive the membrane degasser to shake. If the shaking amplitude is too large, the membrane degasser will be detached, thereby affecting the degassing effect of the water.

[0005] Therefore, in order to solve the above problems, a membrane degassing device for pure water is proposed. Utility Model Content

[0014] 1. The utility model provides a membrane degassing device for pure water, which realizes the clamping of the degassing membrane body through a clamping assembly, and the degassing membrane body is placed inside a connecting tube. When placing, the clamping flanges at both ends of the degassing membrane body are inserted into the connecting flanges at both ends of the connecting tube. When inserted, the bottom of the clamping flange contacts with the clamping block in the clamping box. After the contact, the staff continues to push the clamping flange to descend. During the descent, the bottom of the clamping flange squeezes the clamping block into the clamping box and squeezes the clamping spring at the same time.

During the separation process, the flow of the water flow will drive the membrane degasser to shake. If the shaking amplitude is too large, the membrane degasser will be detached, thereby affecting the degassing effect of the water flow. In order to prevent such incidents from happening, the degassing membrane body 10 is placed inside the connecting tube 1. When placed, the clamping flanges 8 at both ends of the degassing membrane body 10 are inserted into the connecting flanges 2 at both ends of the connecting tube 1. When inserted, the bottom of the clamping flange 8 is aligned with the clamping box. 3, and after contact, the staff continues to push the clamping flange 8 to descend. During the descent, the bottom of the clamping flange 8 squeezes the clamping block 12 into the clamping box 3, and at the same time squeezes the clamping spring 16. When the degassing membrane body 10 fits with the connecting tube 1, the clamping groove 11 opened on the side wall of the clamping flange 8 will be parallel to the clamping block 12. At this time, the clamping spring 16 rebounds, and drives the clamping block 12 to rebound into the clamping groove 11 during the rebound, thereby achieving the clamping effect.

[0028] Further, such as Figure 1 and Figure 2As shown, the slide plate 15 is fixedly connected to the side wall away from the clamping spring 16; the slide plate 15 side wall is fixedly connected to the slide post 13 at the reset spring 14; the top of the clamping box 3 is fixedly connected to the top plate 4; the slide post 13 is arranged through the top plate 4. During operation, the degassing membrane body 10 and the connecting tube 1 are clamped together and the degassing work begins. After the work is completed, when the degassing membrane body 10 needs to be cleaned, the staff can pull the slide post 13. When pulling, the slide post 13 drives the slide plate 15 to move toward the top plate 4, and drives the clamping spring 16 and the clamping block 12 to rise during the movement. During the rising process, the reset spring 14 is squeezed, and when the clamping block 12 rises, the clamping block 12 and the clamping groove 11 are separated from the clamping effect. After separation, the staff can take out the degassing membrane body 10. After taking it out, the staff releases the slide post 13, and then the reset spring 14 rebounds, and the clamping block 12 is ejected from the clamping box 3 again, waiting for the next clamping of the degassing membrane body 10.

[0029] Further, such as Figure 1 As shown, the inner wall of the clamping flange 8 is fixedly connected with a connecting pipe 7; the connecting pipe 7 is provided with two groups. When working, the connecting pipe 7 can be connected with the water inlet pipe and the drain pipe of pure water, and then the pure water enters the degassing membrane body 10 through the connecting pipe 7 and is degassed by the degassing membrane body 10.

[0030] Further, such as Figure 1 As shown, there are four groups of snap-in boxes 3, which are respectively arranged on the side walls of the connecting flange 2 at both ends of the connecting tube 1; the end of the sliding column 13 is fixedly connected to a pull rod 5; the pull rod 5 is sleeved with an anti-slip sleeve 6. When working, the four groups of snap-in boxes 3 are respectively arranged on both sides of the connecting flange 2, and two groups of snap-in boxes 3 are arranged on each side. The degassing membrane body 10 can be snapped together through the four groups of snap-in boxes 3. After the snap-in is completed, the degassing process can be started. The two ends of the pull rod 5 are respectively fixedly connected to the sliding columns 13 in the two groups of snap-in boxes 3. By pulling the pull rod 5, the sliding column 13 and the slide plate 15 can be driven to rise, so that the snap-in flange 8 can be unstuck, and the anti-slip sleeve 6 can prevent the pull rod 5 from falling off.

[0031] Further, such as Figure 6 As shown, the inner wall of the snap-in box 3 is provided with a limiting groove 17; the limiting groove 17 is provided with two groups; the two ends of the slide plate 15 are slidably connected in the limiting groove 17, and when working, the protruding parts at the two ends of the slide plate 15 are slidably connected in the limiting grooves 17 on both sides of the snap-in box 3, and the limiting grooves 17 can prevent the slide plate 15 from being offset when sliding.

[0032] Further, such as Figure 2As shown, the connecting flange 2 is square; the clamping flange 8 is round; the anti-slip sleeve 6 is made of rubber. When working, the square connecting flange 2 is arranged at both ends of the connecting tube 1, and the inner wall is round, which is compatible with the clamping flange 8, and the rubber material can play an anti-slip effect.

[0033] Working principle: In the current prior art, the membrane degasser is placed in a clamping cylinder. After being clamped by the clamping cylinder, water flows through the membrane degasser, thereby using the membrane degasser to separate the gas in the water flow. During the separation process, the flow of water will drive the membrane degasser to shake. If the shaking amplitude is too large, the membrane degasser will be detached, thereby affecting the degassing effect of the water flow. In order to prevent such incidents from happening, the degassing membrane body 10 is placed inside the connecting cylinder 1. When placed, the clamping flanges 8 at both ends of the degassing membrane body 10 are inserted into the two ends of the connecting cylinder 1. The connecting flange 2 is inserted into the connecting flange 2. When inserted, the bottom of the connecting flange 8 contacts the connecting block 12 in the connecting box 3. After the contact, the staff continues to push the connecting flange 8 to descend. During the descent, the bottom of the connecting flange 8 squeezes the connecting block 12 into the connecting box 3 and squeezes the connecting spring 16 at the same time. When the degassing membrane body 10 is fitted with the connecting tube 1, the connecting groove 11 on the side wall of the connecting flange 8 will be parallel to the connecting block 12. At this time, the connecting spring 16 rebounds, and drives the connecting block 12 to rebound into the connecting groove 11 during the rebound, thereby achieving the connecting effect.

[0034] Among them, the connection between the clamping flange 8 and the connecting flange 2 is released by the sliding column 13. After the clamping of the degassing membrane body 10 and the connecting tube 1 is completed, the degassing work begins. After the work is completed, when the degassing membrane body 10 needs to be cleaned, the staff can pull the sliding column 13. When pulling, the sliding column 13 drives the slide plate 15 to move toward the top plate 4, and drives the clamping spring 16 and the clamping block 12 to rise during the movement. During the rising process, the reset spring 14 is squeezed, and when the clamping block 12 rises, the clamping block 12 and the clamping groove 11 are separated from the clamping effect. After separation, the staff can take out the degassing membrane body 10. After taking it out, the staff releases the sliding column 13, and then the reset spring 14 rebounds, and the clamping block 12 is ejected from the clamping box 3 again, waiting for the next clamping of the degassing membrane body 10.
