Description

Technical Field

[0001] This utility model relates to the field of dehumidification technology, specifically to a dehumidification mechanism inside a gas cylinder. Background Technology

[0002] A gas cylinder body refers to a bottle-shaped metal or non-metal sealed container with a volume not exceeding 1000 liters, used for storing and transporting permanent gases, liquefied gases, dissolved gases, or adsorbed gases. It is a mobile, reusable pressure vessel. The gas cylinder body consists of a cylinder body, cylinder cap, cylinder valve, and shock-absorbing rubber ring, among which the cylinder valve, cylinder cap, and shock-absorbing rubber ring are safety accessories of the gas cylinder body and play a very important role in the safe use of the gas cylinder body.

[0003] In existing technologies, traditional gas cylinders are often dehumidified by filling them with dry, high-pressure gas. While this method is simple to operate, its mechanism has fundamental limitations: filling with dry gas mainly relies on increasing the pressure inside the cylinder to reduce the relative humidity of the gas, rather than actually reducing the absolute moisture content. Therefore, this method cannot completely remove moisture from the cylinder and is only suitable for preliminary drying of empty cylinders or for storing gases that are not sensitive to humidity conditions. For applications with strict requirements on moisture content, this method is often insufficient and cannot meet high-standard process requirements. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dehumidification mechanism for the inside of a gas cylinder.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A dehumidification mechanism for a gas cylinder includes a gas cylinder body, a mounting rack on the bottom surface of the gas cylinder body, and a dehumidification assembly on the top surface of the gas cylinder body. The dehumidification assembly includes a heating tube disposed on the top surface of the gas cylinder body, a heating resistance wire fixedly installed on the outer circular wall of the heating tube, an air inlet pipe fixedly installed on the inner circular wall of the heating tube away from the gas cylinder body, a fan fixedly installed on the inner circular wall of the air inlet pipe, and a threaded tube fixedly installed on the inner circular wall of the heating tube near the gas cylinder body, the inner circular wall of the threaded tube being threaded, and a dehumidification tube threadedly connected to the end of the threaded tube near the gas cylinder body, the outer circular wall of the dehumidification tube being threaded.

[0006] In order to continuously monitor the humidity inside the gas cylinder in real time and avoid workers blindly continuing to heat and dehumidify, as a gas cylinder internal dehumidification mechanism of this utility model, preferably, a humidity sensor is fixedly installed on the outer circular wall of the dehumidification tube.

[0007] To ensure that the two arc-shaped grooves fit snugly against the outer circular wall of the gas cylinder body, thereby limiting the position of the gas cylinder body and preventing displacement during dehumidification, as a preferred internal dehumidification mechanism for gas cylinders according to this utility model, a fixing block is fixedly installed on one side of the inner side of the placement frame, and an electric push rod is fixedly installed on the side of the fixing block near the gas cylinder body. Two clamping blocks are provided inside the placement frame, arranged symmetrically. An arc-shaped groove is formed on one side of each clamping block. One end of the telescopic rod of the electric push rod is fixedly installed to the clamping block located on the right side of the placement frame. Two telescopic tubes are fixedly installed on the side of the clamping block near the electric push rod. A fixing rod is movably sleeved on the inner circular wall of each telescopic tube. The end of the fixing rod away from the electric push rod is fixedly installed to the clamping block located on the left side of the placement frame, and the clamping block away from the electric push rod is fixedly installed to one side of the placement frame.

[0008] In order to make the sponge adhere more tightly and evenly to the surface of the gas cylinder body, prevent scratches during clamping and releasing, and protect the gas cylinder body, as a gas cylinder internal dehumidification mechanism of this utility model, preferably, the inner circular wall of the arc groove is fixedly installed with a sponge.

[0009] To allow the dehumidification tube to move left and right, facilitating the removal of the dehumidification tube and placement of the gas cylinder body into the storage rack, as a preferred internal dehumidification mechanism for the gas cylinder according to this utility model, the outer circular wall of the air inlet tube is movably engaged with a clamp, the outer circular wall of the clamp is fixedly mounted with a support column, the bottom surface of the support column is fixedly mounted with a first sliding block, and the top surface of the storage rack is fixedly mounted with a sliding base, the sliding base being slidably connected to the first sliding block.

[0010] To limit the position of the first sliding block and achieve a locking effect upon release, preventing the dehumidification tube from shaking after moving to the appropriate position and thus avoiding affecting the dehumidification effect, as a preferred internal dehumidification mechanism for a gas cylinder according to this utility model, the top surface of the sliding base is provided with a sliding groove, and the inner sides of the sliding groove are respectively provided with serrated grooves. A second sliding block is movably sleeved inside the sliding groove. A spring is fixedly installed on the top surface of the second sliding block, a limit block is fixedly installed on the top surface of the spring, and a button is fixedly installed on the top surface of the limit block.

The hot air is blown to the bottom of the inside of the gas cylinder body, and then the dehumidification operation inside the gas cylinder body begins, ensuring that the internal environment of the gas cylinder body is kept dry. 2. By using the fixed rod, telescopic tube, electric push rod, fixed block and clamping block in cooperation, the two arc grooves can fit against the outer circular wall of the gas cylinder body, thereby limiting the position of the gas cylinder body and preventing the gas cylinder body from shifting during the dehumidification process, so that the staff can carry out dehumidification operation on the gas cylinder body. 3. Through the coordinated use of clamps, support columns, clamping blocks, first sliding blocks and buttons, the dehumidification tube can be moved left and right, thereby adjusting the position of the dehumidification tube and realizing the horizontal position adjustment of the dehumidification tube, which makes it easier to put the gas cylinder body into the inside of the placement rack. 4. Through the coordinated use of spring, button, pressing block, limit block and second sliding block, pressing the button releases the fixation of the dehumidification tube position, so that the position of the first sliding block can be limited, achieving the effect of locking when released, preventing the dehumidification tube from shaking after moving to the appropriate position, and avoiding affecting the dehumidification effect.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Reference Figure 1 , Figure 3 and Figure 4 A dehumidification mechanism for a gas cylinder includes a gas cylinder body 1, a mounting rack 2 on the bottom surface of the gas cylinder body 1, a dehumidification assembly on the top surface of the gas cylinder body 1, a heating tube 3 on the top surface of the gas cylinder body 1, a heating resistance wire 4 fixedly installed on the outer circular wall of the heating tube 3, an air inlet pipe 5 fixedly installed on the inner circular wall of the heating tube 3 away from the gas cylinder body 1, a fan 8 fixedly installed on the inner circular wall of the air inlet pipe 5, a threaded pipe 6 fixedly installed on the inner circular wall of the heating tube 3 near the gas cylinder body 1, a thread on the inner circular wall of the threaded pipe 6, a dehumidification pipe 7 threadedly connected to the end of the threaded pipe 6 near the gas cylinder body 1, a humidity sensor 18 fixedly installed on the outer circular wall of the dehumidification pipe 7, and a thread on the outer circular wall of the dehumidification pipe 7. When dehumidifying the gas cylinder body 1, the dehumidifying tube 7 is rotated counterclockwise. Since the threaded tube 6 and the dehumidifying tube 7 are connected by threads, the dehumidifying tube 7 begins to move downwards. When the bottom of the dehumidifying tube 7 reaches the bottom of the inside of the gas cylinder body 1, the fan 8 blows outside air into the air inlet tube 5. After the air enters the heating tube 3 from the inside of the air inlet tube 5, the heating resistance wire 4 starts to heat up, and the air inside the air inlet tube 5 is heated. Outside air continuously enters the heating tube 3, causing the hot air to flow through the heating tube 3 to the dehumidifying tube 7. The hot air is blown to the bottom of the inside of the gas cylinder body 1, thus starting the dehumidification operation inside the gas cylinder body 1, ensuring that the internal environment of the gas cylinder body 1 remains dry. The humidity sensor 18 can continuously monitor the humidity inside the gas cylinder body 1 in real time, avoiding blindly continuing to heat and dehumidify.

[0016] refer to Figure 2 , Figure 5 and Figure 6 A fixing block 12 is fixedly installed on one side of the inside of the placement rack 2. An electric push rod 11 is fixedly installed on the side of the fixing block 12 close to the gas cylinder body 1. Two clamping blocks 13 are provided inside the placement rack 2. The two clamping blocks 13 are arranged symmetrically. An arc groove is opened on one side of the clamping block 13. One end of the telescopic rod of the electric push rod 11 is fixedly installed with the clamping block 13 located on the right side of the placement rack 2. Two telescopic tubes 10 are fixedly installed on the side of the clamping block 13 close to the electric push rod 11. A fixing rod 9 is movably sleeved on the inner circular wall of the telescopic tube 10. The end of the fixing rod 9 away from the electric push rod 11 is fixedly installed with the clamping block 13 located on the left side of the placement rack 2. The clamping block 13 away from the electric push rod 11 is fixedly installed with one side of the placement rack 2. A sponge 14 is fixedly installed on the inner circular wall of the arc groove. When the staff places the gas cylinder body 1 into the placement rack 2 using the clamping block 13, the electric push rod 11 pushes the clamping block 13 forward, causing the fixing rod 9 to retract into the telescopic tube 10. The distance between the two clamping blocks 13 then decreases, allowing the two arc-shaped grooves to fit against the outer circular wall of the gas cylinder body 1, thereby limiting the position of the gas cylinder body 1 and preventing it from shifting during dehumidification, which would make it inconvenient for the staff to work. The sponge 14, through compression and deformation, allows the sponge 14 to fit more tightly and evenly against the surface of the gas cylinder body 1, preventing scratches during clamping and releasing and protecting the gas cylinder body 1.

[0017] refer to Figure 1 , Figure 2 , Figure 7 and Figure 8The outer circular wall of the air inlet pipe 5 is movably clamped with a clamp 16, and a support column 17 is fixedly installed on the outer circular wall of the clamp 16. A first sliding block 20 is fixedly installed on the bottom surface of the support column 17. A sliding base 19 is fixedly installed on the top surface of the placement rack 2. The sliding base 19 is slidably connected to the first sliding block 20. A sliding groove 26 is opened on the top surface of the sliding base 19. A serrated groove 23 is opened on both sides of the inside of the sliding groove 26. A second sliding block 25 is movably sleeved inside the sliding groove 26. A spring 15 is fixedly installed on the top surface of the second sliding block 25. A limit block 24 is fixedly installed on the top surface of the spring 15. A button 21 is fixedly installed on the top surface of the limit block 24. A pressing hole 22 is opened on the top surface of the first sliding block 20. The inner circular wall of the pressing hole 22 is movably sleeved with the outer circular wall of the button 21. The first sliding block 20 slides on the top surface of the sliding base 19, causing the support column 17 to move. The support column 17 then moves the clamp 16, which in turn moves the air inlet pipe 5. The air inlet pipe 5 then moves the heating pipe 3, allowing the dehumidification pipe 7 to move left and right. This allows for adjustment of the dehumidification pipe 7's position, enabling horizontal adjustment and facilitating the placement of the gas cylinder body 1 into the storage rack 2. When the dehumidification pipe 7 needs to be moved, pressing the button 21 causes the button 24 to press against the limit block 24. 4. The spring 15 will be pressed by the limiting block 24, and the spring 15 will begin to retract. The limiting block 24 will move down until the limiting block 24 is engaged in the serrated groove 23. Then the first sliding block 20 can drive the support column 17 to move to the appropriate position. When the button 21 is released, the spring 15 will begin to rebound and drive the limiting block 24 to rise. The top surface of the limiting block 24 will abut against the top surface of the serrated groove 23. By pressing the button 21, the position of the dehumidification tube 7 will be released, so that the position of the first sliding block 20 can be limited, achieving the effect of locking when released, preventing the dehumidification tube 7 from shaking after moving to the appropriate position, and avoiding affecting the dehumidification effect.

[0018] Working principle: Please refer to Figures 1-8 As shown, when the staff needs to dehumidify the gas cylinder body 1 through the dehumidification tube 7, they first rotate the dehumidification tube 7 counterclockwise. Since the threaded tube 6 and the dehumidification tube 7 are connected by threads, the dehumidification tube 7 begins to move downwards. When the bottom of the dehumidification tube 7 reaches the bottom of the inside of the gas cylinder body 1, the fan 8 blows outside air into the inside of the air inlet tube 5. After the air enters the inside of the heating tube 3 from the inside of the air inlet tube 5, the heating resistance wire 4 starts to heat up. The air inside the air inlet tube 5 is heated, and outside air continuously enters the inside of the heating tube 3, causing the hot air to flow through the heating tube 3 to the dehumidification tube 7. The hot air is blown to the bottom of the inside of the gas cylinder body 1, and then the dehumidification operation inside the gas cylinder body 1 begins, ensuring that the internal environment of the gas cylinder body 1 remains dry.

[0019] When the staff places the gas cylinder body 1 into the placement rack 2 using the clamping block 13, the electric push rod 11 pushes the clamping block 13 forward, causing the fixing rod 9 to retract into the telescopic tube 10. The distance between the two clamping blocks 13 then decreases, allowing the two arc-shaped grooves to fit against the outer circular wall of the gas cylinder body 1, thereby limiting the position of the gas cylinder body 1 and preventing it from shifting during dehumidification, which would make it inconvenient for the staff to work.

[0020] The first sliding block 20 slides on the top surface of the sliding base 19, causing the support column 17 to move. The support column 17 then moves the clamp 16, which in turn moves the air inlet pipe 5. The air inlet pipe 5 then moves the heating pipe 3, allowing the dehumidification pipe 7 to move left and right. This allows the position of the dehumidification pipe 7 to be adjusted, enabling the horizontal position adjustment of the dehumidification pipe 7. This facilitates the removal of the dehumidification pipe 7 and the placement of the gas cylinder body 1 into the storage rack 2.

[0021] By using the limit block 24, when the position of the dehumidification tube 7 needs to be moved, pressing the button 21 will compress the limit block 24, causing the spring 15 to be compressed by the limit block 24. The spring 15 will then retract, and the limit block 24 will move downwards until it is engaged in the serrated groove 23. Then, the first sliding block 20 can move the support column 17 to the appropriate position. Releasing the button 21 will cause the spring 15 to rebound, and the spring 15 will cause the limit block 24 to rise. The top surface of the limit block 24 will then press against the top surface of the serrated groove 23. Pressing the button 21 will release the fixation of the dehumidification tube 7, thus limiting the position of the first sliding block 20 and achieving the effect of locking upon release. This prevents the dehumidification tube 7 from shaking after being moved to the appropriate position, thus avoiding affecting the dehumidification effect.
