Description

Technical Field

[0001] The utility model relates to the technical field of storage equipment, in particular to a liquid oxygen safety storage device. Background Art

[0002] When storing liquid oxygen in cryogenic pressure vessels, it is crucial to completely remove solid particulate impurities from the cryogenic liquid oxygen. Liquid oxygen often contains solid particulate hydrocarbons, such as acetylene. During air separation to produce liquid oxygen, some acetylene may enter the liquid oxygen due to incomplete separation. When the acetylene concentration in the liquid oxygen exceeds its solubility limit, the acetylene precipitates as white solid particles and becomes suspended in the liquid oxygen. These suspended acetylene particles collide with each other, creating combustion conditions that can cause explosions. If a container that has been repeatedly filled with liquid oxygen is not promptly drained, the liquid oxygen remaining at the bottom of the container after each drain, if it contains acetylene particles, may accumulate over time and increase in concentration, making it more likely to reach combustion conditions. Publication No. CN209922071U discloses a safe storage device for liquefied oxygen: comprising a tank body, an inner storage chamber disposed within the tank body, the inner diameter of the inner storage chamber being arranged to gradually decrease vertically from top to bottom in a stepped manner; a liquid inlet pipe disposed at the top of the inner storage chamber and a liquid outlet pipe disposed at the bottom; and a conical bottom of the inner storage chamber converging toward the liquid outlet pipe. The utility model provides a conical bottom of the inner storage chamber, allowing the liquid inside to be drained promptly and effectively preventing excessive accumulation of impurities in the inner storage chamber that could affect the safety of liquid oxygen storage. However, the above technology still has some drawbacks. For example, existing storage devices often have removable covers for easy cleaning, which can easily reduce the sealing effect after prolonged use, resulting in poor practicality and requiring improvement.

When in use, the sealing plate 9 is aligned with the upper sealing groove 4 and pressed downward to make the sealing plate 9 completely slide into the interior of the tank body 1 through the sealing groove 4, and the card block 16 slides into the interior of the fixed plate 5 through the card slot 6, and the top plate 14 drives the card plate 15 to completely slide to the surface of the fixed plate 5. At this time, pinch the turning handle 19 to match the threaded rod 18 with the upper rotating groove 8 and rotate it, so that the threaded rod 18 passes through the top plate 14 through the fixed groove 17, and is completely rotated into the interior of the fixed block 7 through the rotating groove 8 to firmly fix the cover plate 10. The top plate 14 is connected to the fixing plate 5, and the card plate 15 is connected to the fixing plate 5, which is convenient for cleaning and easy to remove, so that the sealing effect of the fixing plate 10 is reduced after long-term use. The fixing blocks 7 are symmetrically distributed at the bottom end of the fixing plate 5. The sealing plate 9 slides inside the tank body 1 through the sealing groove 4. The sliding connection between the cover plate 10 and the tank body 1 makes it easier for the sealing plate 9 to slide, and prevents the sealing plate 9 from being stuck by the tank body 1 during use. The sliding connection between the top plate 14 and the fixing plate 5 and the sliding connection between the card plate 15 and the fixing plate 5 make it easier for the top plate 14 and the card plate 15 to slide, and prevents the top plate 14 and the card plate 15 from being stuck during use. The fixed plate 5 is stuck, causing the top plate 14 and the card plate 15 to be unable to continue sliding. The blocking blocks 16 are evenly distributed at the bottom end of the top plate 14, and the blocking blocks 16 slide inside the fixed plate 5 through the card groove 6, which is more convenient for the blocking blocks 16 to slide, and avoids the blocking blocks 16 being stuck by the fixed plate 5 during use, causing the blocking blocks 16 to be unable to continue sliding. The threaded rod 18 rotates inside the fixed block 7 through the rotating groove 8, and the threaded rod 18 slides inside the top plate 14 through the fixed groove 17. The turning handle 19 is rotatably connected to the top plate 14, which is more convenient for the threaded rod 18 to rotate, and avoids the threaded rod 18 being stuck by the fixed block 7 or the top plate 14 during use, causing the threaded rod 18 to be unable to continue rotating.

[0026] Example 2

[0027] See also Figure 1-3 6. A mounting plate 20 is installed on the surface of the tank body 1, and a protective pad 21 is installed on the surface of the mounting plate 20. A buffer pad 22 is installed on the surface of the protective pad 21 to better protect the surface of the tank body 1. When the surface of the tank body 1 is bumped during use, the buffer pad 22 on the surface can be deformed and partially alleviate the impact force generated by the bump, and the remaining impact force will be buffered by the protective pad 21, thereby preventing the tank body 1 from being damaged due to bumps during use. The protective pad 21 is evenly wrapped on the surface of the mounting plate 20, and the buffer pads 22 are evenly distributed on the surface of the protective pad 21, which better protects the tank body 1 and avoids the tank body 1 from being damaged due to uneven protection during use.

[0028] Working principle: When in use, first place the tank body 1 in the required position, so that the support column 2 can firmly support the tank body 1, and then the cover plate 10 corresponds to the top of the tank body 1, and the sealing plate 9 corresponds to the sealing groove 4, and then press the cover plate 10 downward to make the sealing plate 9 slide downward on the top of the tank body 1 through the sealing groove 4, and the top plate 14 drives the card plate 15 to slide downward on the top of the tank body 1. When the sealing plate 9 completely slides into the interior of the tank body 1 through the sealing groove 4, and the card block 16 completely slides into the interior of the fixed plate 5 through the card groove 6, the card plate 15 is stuck on the surface of the fixed plate 5. At this time, pinch the turning handle 19 to match the threaded rod 18 with the upper fixed groove 17 and press it downward, so that the threaded rod 18 passes through the fixed groove 17 through the top plate 14 and is connected to the turning handle 19. The movable groove 8 corresponds to it, and then the handle 19 is turned to make the threaded rod 18 rotate downward on the top of the fixed block 7 through the rotating groove 8. When the threaded rod 18 is completely rotated into the interior of the fixed block 7 through the rotating groove 8, the cover plate 10 can be firmly clamped on the top of the tank body 1. Finally, the pipeline is connected to the top of the feed port 11, and the valve 12 is opened by the switch 13 to start delivering liquid oxygen. In daily use, the protective pad 21 and the buffer pad 22 fixed to the surface of the tank body 1 by the mounting plate 20 can effectively protect the tank body 1, thereby preventing the tank body 1 from being damaged due to collision during daily use, and in the later stage, the staff can discharge the liquid oxygen inside the tank body 1 through the discharge port 3 for use.
