Description

Technical Field

[0001] This invention relates to a storage device for chemical gases, belonging to the field of chemical gas storage technology. Background Technology

[0002] Chemical gases typically include flammable and explosive gases such as hydrogen, methane, ethane, and carbon monoxide. They are prone to combustion and even explosion under open flames or high temperatures, and are often used as fuel to provide energy to equipment. However, these gases are in various states, and for the safety of operators, chemical gas storage tanks are usually used to store them and reduce leakage. Chemical gas storage tanks are specialized devices for storing industrial gases. Because many chemical gases are hazardous, the scientific management of these tanks is crucial to prevent leaks that could endanger workers.

[0003] Chinese utility model patent CN219828540U discloses a vertical air storage tank, including a tank body. An exhaust flange connects to the outer wall of the tank body, an inlet flange connects to the top of the tank body, four support structures are inclined at the bottom of the tank body, a protective railing surrounds the top of the tank body, a gas detection structure for detecting gas leaks is located on the top of the exhaust flange, and a ladder structure for climbing to the top of the tank body is also provided on the outer wall of the tank body. This vertical air storage tank uses an exhaust fan to guide the special gas leaking from the exhaust flange into a gas sensor, allowing the gas sensor to analyze and detect multiple gases. It then determines whether the concentration of the special gas indicates a risk of leakage, and a warning light provides an indication, facilitating appropriate protective and rescue measures for personnel. By inserting support rods on the ladder into two limit blocks, it is convenient for personnel to climb the ladder to the top of the tank for maintenance, improving the practicality of the storage tank. However, in the prior art, the ladder is directly exposed, and in freezing weather, the climbing rods are prone to icing and slipping, reducing safety.

[0004] Therefore, there is a need for a storage device for chemical gases to prevent the ladder from freezing and to avoid the ladder from icing up. Summary of the Invention

[0009] The climbing unit includes a moving tube and a mounting hole. The mounting hole is set on the fixed box. The moving tube is parallel to the front-back direction and passes through the mounting hole. The moving tube slides and is sealed to the inner wall of the mounting hole. A transmission rod is fixedly installed on the outer peripheral wall of the moving tube.

[0010] The moving unit includes a rotating shaft parallel to the left-right direction. The rotating shaft is rotatably connected to a fixed box. A rotating disk is coaxially fixed at one end of the rotating shaft and located inside the fixed box. The rotating disk has two arc-shaped grooves, each corresponding to one of the two climbing units. The distance between one end of the groove and the axis of the rotating shaft is greater than the distance between the other end of the groove and the axis of the rotating shaft.

[0050] like Figure 1-15 As shown, a storage device for chemical gases in this embodiment includes a tank 1, which is arranged vertically. The tank 1 is provided with an air inlet 2 and an air outlet 3, which are respectively located at the top and bottom of the tank 1. A ladder mechanism 4 is provided on one side of the tank 1.

[0051] The climbing mechanism 4 includes a fixed box 41, which is fixedly installed on the outer wall of the tank 1. The fixed box 41 is provided with a driving component 42 and multiple climbing components 43, which are distributed from top to bottom.

[0052] The climbing component 43 includes a moving unit 431 and two climbing units 432, the two climbing units 432 are arranged symmetrically front to back, the moving unit 431 is located between the two climbing units 432, the moving unit 431 is connected to the two climbing units 432, and the driving unit 422 is connected to the moving unit 431.

[0053] The climbing unit 432 includes a moving tube 4321 and a mounting hole 4322. The mounting hole 4322 is disposed on the fixed box 41. The moving tube 4321 is parallel to the front-back direction and passes through the mounting hole 4322. The moving tube 4321 slides and is sealed to the inner wall of the mounting hole 4322. A transmission rod 4323 is fixedly disposed on the outer peripheral wall of the moving tube 4321. The transmission rod 4323 is connected to the moving unit 431. The driving force is provided by the driving assembly 42 to make the moving unit 431 drive the moving tube 4321 to move in the front-back direction.

[0054] The outer end of the moving tube 4321 is sealed and fixedly provided with a positioning block 4324;

[0055] The moving unit 431 includes a rotating shaft 4311, which is parallel to the left-right direction. The rotating shaft 4311 is rotatably connected to the fixed box 41 via a bearing 4312. A rotating disk 4313 is coaxially fixed at one end of the rotating shaft 4311 and is located inside the fixed box 41. The rotating disk 4313 has two arc-shaped sliding grooves 4314, which correspond one-to-one with two climbing units 432. The distance between one end of the sliding groove 4314 and the axis of the rotating shaft 4311 is greater than the distance between the other end of the sliding groove 4314 and the axis of the rotating shaft 4311. One end of the transmission rod 4323 is inserted into the sliding groove 4314 and is slidably connected to the inner wall of the sliding groove 4314. The rotating shaft 4311 is connected to the drive assembly 42, and the rotation of the rotating shaft 4311 is realized through the drive assembly 42.

[0056] The drive assembly 42 includes a rocker wheel 421, which is mounted on one of the rotating shafts 4311. The rocker wheel 421 is located outside the fixed box 41. Two adjacent rotating shafts 4311 are connected by a drive unit 422, which is located inside the fixed box 41.

[0057] The drive unit 422 includes a first transmission wheel 4221 and a second transmission wheel 4222. The first transmission wheel 4221 and the second transmission wheel 4222 are respectively mounted on two adjacent rotating shafts 4311. The first transmission wheel 4221 and the second transmission wheel 4222 are connected by a transmission belt 4223.

[0058] The fixed box 41 is provided with an air inlet pipe 4325, and the moving pipe 4321 is provided with two sets of first air holes 4326. The two sets of first air holes 4326 are distributed vertically, and each set of first air holes 4326 has multiple first air holes 4326. The multiple first air holes 4326 in the same set are arranged along the length of the moving pipe 4321.

[0059] The top of the tank 1 is provided with a protective mechanism 5, which includes an annular protective tube 51. The protective tube 51 is arranged coaxially with the tank 1 and is located above the tank 1. The protective tube 51 is connected to the fixed box 41 through a connecting tube 52. Multiple fixed tubes 53 are provided between the protective tube 51 and the tank 1. The multiple fixed tubes 53 are evenly distributed circumferentially with the vertical axis of the tank 1 as the center. One end of the fixed tube 53 is fixedly installed on the protective tube 51, and the other end of the fixed tube 53 is fixedly and sealed on the tank 1. A second vent 54 is provided on the side of the fixed tube 53 near the vertical circumferential direction of the tank 1.

[0060] The bottom of the protective tube 51 is provided with a plurality of third air holes 55, and the plurality of third air holes 55 are arranged alternately with a plurality of fixed tubes 53.

[0061] The protective tube 51 is provided with a sealing component 56, which is used to seal the third vent 55.

[0062] The sealing assembly 56 includes a sealing tube 561, which is sleeved on the protective tube 51, and the sealing tube 561 and the protective tube 51 are slidably and sealingly connected.

[0063] An annular rotating ring 562 is provided above the protective tube 51, and the rotating ring 562 is fixedly connected to the sealing tube 561.

[0064] Two rocker wheels 421 are provided, one of which is installed on the lowermost rotating shaft 4311 and the other is installed on the uppermost rotating shaft 4311.

[0065] A roller 4327 is installed at one end of the transmission rod 4323. The roller 4327 matches the slide groove 4314 and is located inside the slide groove 4314.

[0066] The climbing mechanism 4 has the following two states:

[0067] In the first state, the positioning block 4324 abuts against the outer wall of the fixed box 41, and the moving tube 4321 retracts into the fixed box 41.

[0068] This not only improves the antifreeze capability of the mobile pipe 4321, preventing workers from slipping when climbing it, but also prevents it from being corroded by rainwater, thus improving its rust resistance.

[0069] In the second state, one end of the moving tube 4321 connected to the positioning block 4324 is located on the outer wall of the fixed box 41, and the part of the moving tube 4321 extending out of the fixed box 41 is used for workers to climb.

[0070] When staff are climbing, the climbing mechanism 4 is in the second state; when there is no need to climb, the climbing mechanism 4 is in the first state.

[0071] When switching between the first and second states, the rocker wheel 421 is rotated, causing the rotating shaft 4311 to rotate. The rotation of the rotating shaft 4311 drives the first transmission wheel 4221 to rotate. The rotation of the first transmission wheel 4221 drives the second transmission wheel 4222 to rotate via the transmission belt 4223. The rotation of the second transmission wheel 4222 causes the adjacent rotating shafts 4311 to rotate. In this way, all rotating shafts 4311 can rotate synchronously. The rotation of the rotating shaft 4311 also drives the rotating disk 4313 to rotate. During the rotation of the rotating disk 4313, the transmission rod 4323 is pushed to move in the front-back direction through the slide groove 4314. The roller 4327 can convert the sliding friction between the transmission rod 4323 and the slide groove 4314 into rolling friction, reducing the frictional force. The movement of the transmission rod 4323 drives the moving tube 4321 to move synchronously, and the two moving tubes 4321 in the same climbing component 43 move in opposite directions.

[0072] In addition, the air inlet pipe 4325 is connected to an air supply device, which can be an air pump. The air supply device delivers air to the fixed box 41. A portion of the air in the fixed box 41 is delivered to the moving pipe 4321. The air in the moving pipe 4321 is then discharged from the first air hole 4326. Another portion of the air in the fixed box 41 is delivered to the protective pipe 51 through the connecting pipe 52. A portion of the air in the protective pipe 51 is discharged from the third air hole 55. Another portion of the air in the protective pipe 51 is delivered to the fixed pipe 53. The air in the fixed pipe 53 is then discharged from the second air hole 54.

[0073] During freezing weather, when workers are climbing, the climbing mechanism 4 is in its second state. The third air hole 55 is sealed by the sealing pipe 561, and the air supplied from the air inlet pipe 4325 to the fixed box 41 is hot air. The heat in the air is transferred to the moving pipe 4321, which can prevent the moving pipe 4321 from freezing and slipping, thus improving safety. The first air hole 4326 can also increase the friction between the moving pipe 4321 and the worker's hands and feet. When the worker climbs to the top of the tank 1, he rotates the upper rocker wheel 421 to put the climbing mechanism 4 in its first state. In this way, all the air in the fixed box 41 is supplied to the fixed pipe 53 and discharged from the second air hole 54. The air discharged from the second air hole 54 acts on the top of the tank 1 to thaw the top of the tank 1, preventing the top of the tank 1 from slipping and further improving safety.

[0074] When the ambient temperature is too high, the air inlet pipe 4325 delivers cold air into the fixed box 41. At this time, the climbing mechanism 4 is in the first state. Rotating the rotating ring 562 causes the sealing pipe 561 to move on the protective pipe 51 and stops the sealing pipe 561 from sealing the third vent 55. Part of the air in the protective pipe 51 is discharged from the third vent 55 and acts downward on the tank 1. The cold air has a lower density. The other part of the air in the protective pipe 51 is delivered to the fixed pipe 53. The air in the fixed pipe 53 is then discharged from the second vent 54 and acts on the top of the tank 1. In this way, the tank 1 is cooled down, avoiding the tank 1 from overheating and causing safety accidents, thus improving the safety of chemical gas storage.

[0075] In summary, during the climbing process, hot air is delivered into the moving pipe 4321 and then discharged through the first air vent 4326, allowing the heat in the air to be transferred to the moving pipe 4321. This prevents the moving pipe 4321 from freezing and slipping, thus improving safety. Furthermore, the hot air can also be discharged through the second air vent 54 and act on the top of the tank 1, preventing slippage at the top of the tank 1 and further improving safety. Secondly, when workers need to climb, the moving pipe 4321 extends out of the fixed box 41; when workers do not need to climb, the moving pipe 4321... The retraction of the mobile tube 4321 into the fixed box 41 not only improves the antifreeze capability of the mobile tube 4321 and prevents workers from slipping when climbing it, but also prevents the mobile tube 4321 from being corroded by rainwater, thus improving its rust resistance. Furthermore, when the ambient temperature is too high, cold air is introduced into the fixed box 41 and discharged through the second air vent and the third air vent 55, which acts on the tank 1 to cool it down, preventing the tank 1 from overheating and causing safety accidents, thereby improving the safety of chemical gas storage.

[0076] In addition to the above embodiments, the present invention also includes other embodiments. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of the present invention.
