After the treatment is completed, open the balance gas valve, increase the pressure in the pipeline to P, continue to control the flow rate when adding in the same way as above, when the weight on the balance reaches the required weight, close all the first gas filling tanks and the second gas filling tanks, evacuate the pressure in the pipeline, weigh the weight of the first gas filling tank, and calculate the concentration of each substance in the first gas filling tank, which is regarded as the concentration of all gas cylinders.

[0031] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0032] like Figure 1 to Figure 2 As shown, an inflation device for a gas cylinder in a container according to an embodiment of the present invention comprises an inflation detector 1, and inflation tubes 15 are symmetrically installed on both sides of the inflation detector 1, and the ends of the inflation tubes 15 are connected to a first joint 13, and a first inflation tank 12 is fixedly installed at the bottom end of the first joint 13, and the first inflation tank 12 is symmetrically provided with a second inflation tank 14 about the inflation detector 1, and an electronic scale 11 is provided at the bottom end of the first inflation tank 12, and an inflation tightening device 2 is fixedly installed on the outer wall of the end of the inflation tube 15;

[0033] like Figures 2 to 3 As shown, the pneumatic tightening device 2 includes a first support frame 21, a direction fixing member 26 and a direction adjusting member 27. The direction fixing member 26 is fixedly installed on the end of the first support frame 21, and the direction adjusting member 27 is rotatably installed inside the direction fixing member 26. The direction adjusting member 27 is connected to the opening on the first joint 13. The direction adjusting member 27 is used to fit the opening on the first joint 13 to prevent air leakage when the first joint 13 is inflated and connected to the direction adjusting member 27. A locking device 3 is provided inside the first support frame 21, and the locking device 3 is used to lock the direction adjusting member 27.

[0034] It should be noted that, when inflating, the second inflatable tank 14 serves as the inflatable tank, and the first inflatable tank 12 serves as the reference tank. When inflating, the inflatable tightening device 2 on the first inflatable tank 12 needs to be connected to the first joint 13, and the inflatable tightening device 2 on the second inflatable tank 14 needs to be connected to the first joint 13. Considering that the shape of the outer wall of the first joint 13 may be squeezed during connection, and slight deformation occurs due to long-term use, the inflatable tightening device 2 cannot be completely sealed when connected to the first joint 13, resulting in air leakage during inflation. In order to solve this problem, a direction fixing member 26 and a direction adjusting member 27 are provided on the inflatable tightening device 2. During installation, the direction adjusting member 27 can be docked with the interface on the first joint 13, and the direction adjusting member 27 can be movably installed inside the direction fixing member 26, so that the direction adjusting member 27 can contact and squeeze the interface on the first joint 13, and the first support frame 21 The interior of the locking device 3 is connected, and the end of the locking device 3 is provided with a second support frame 22. The end of the second support frame 22 is rotatably connected with a tightening threaded column 23, and the tightening threaded column 23 passes through the end of the second support frame 22. The outer wall of the first joint 13 is squeezed by rotating the tightening threaded column 23, thereby driving the locking device 3 to move, so that the locking device 3 can lock the direction adjustment member 27 to prevent the direction adjustment member 27 from rotating during inflation after installation, and the inflation tube 15 is connected to the direction adjustment member 27. When the installation is completed, the inflation work can be carried out, and the inflation detector 1 is started for inflation, so that the gas inside the second inflation tank 14 can be filled into the inside of the first inflation tank 12. Until the inflation is completed, the tightening threaded column 23 is rotated to loosen it, and the locking device 3 can be loosened. After that, the direction adjustment member 27 is automatically reset, and the first inflation tank 12 can be moved away for the next round of inflation.

[0035] like Figures 2 to 4 As shown, the inflatable tightening device 2 includes a first support frame 21 fixedly installed on the outer wall of the inflatable tube 15, and a direction fixing member 26 is fixedly installed on the side wall of the first support frame 21 connected to the end of the inflatable tube 15, and a direction adjusting member 27 is rotatably installed inside the direction fixing member 26, and a locking device 3 is slidably installed inside the first support frame 21, and the end of the locking device 3 is connected to a second support frame 22, and the second support frame 22 has the same bending shape as the first support frame 21. The second support frame 22 moves, driving the locking device 3 inside the first support frame 21 to limit the direction adjusting member 27, and a tightening threaded column 23 is installed on the internal thread of the second support frame 22, and a first extrusion block 25 is fixedly installed on one end of the tightening threaded column 23, and a handle 24 is fixedly installed on the other end of the tightening threaded column 23.

[0036] It should be noted that a first support frame 21 is fixedly installed on the outer wall of the inflation tube 15, and a direction fixing member 26 and a direction adjusting member 27 are provided on the first support frame 21, and the direction fixing member 26 and the direction adjusting member 27 are in a connected state with the inflation tube 15. Holding the handle 24 drives the tightening threaded column 23 to rotate so that the first extrusion block 25 squeezes the outer wall of the first joint 13, so that the inflation tightening device 2 can be connected with the interface on the first joint 13, and then the direction adjusting member 27 is adaptively connected with the interface on the first joint 13, so that a sealing effect can be achieved, and the second support frame 22 moves in the direction away from the inflation tube 15 under the action of the tightening threaded column 23, thereby driving the locking device 3 to move, and the movement of the locking device 3 can lock the direction adjusting member 27 to prevent the direction adjusting member 27 from shaking during inflation and causing gas leakage, thereby improving the safety during inflation.

[0037] like Figure 3 to Figure 4 As shown, the direction fixing member 26 includes a first fixing plate 261 fixedly installed at the end of the inflation tube 15, an air pipe outlet 262 is arranged inside the first fixing plate 261, a first support column 263 is fixedly installed on the side wall of the first fixing plate 261, a first circular block 266 is fixedly installed on the side wall of the first support column 263, a second support plate 264 is fixedly installed on the outer wall of the first circular block 266, an end of the second support plate 264 is fixedly installed on the side wall of the first support frame 21, a support protrusion 265 is symmetrically installed on the outer wall of the second support plate 264, and an end of the support protrusion 265 is rotatably installed with the locking device 3.

[0038] It should be noted that the first fixed plate 261 is fixedly installed with the trachea outlet 262, and the side wall of the trachea outlet 262 cooperates with the direction adjusting member 27 to improve the sealing degree, and the side wall of the first support column 263 is provided with a first circular block 266, and the first circular block 266 is connected to the second support plate 264, so as to limit the direction adjusting member 27, and the outer wall of the second support plate 264 is provided with a supporting protrusion 265, and the outside of the supporting protrusion 265 is provided with a locking device 3. When the second support frame 22 moves, it drives the locking device 3 to limit the direction adjusting member 27. The two supporting protrusions 265 are symmetrically arranged about the central axis of the second support plate 264, so as to improve the clamping effect and make the force balanced during clamping.

[0039] like Figures 4 to 7As shown, the direction adjustment member 27 includes a sphere 274 rotatably mounted inside the first circular block 266, a center groove 275 is arranged inside the sphere 274, a first adjustment plate 271 is fixedly mounted on the outer wall of the sphere 274, a first spring 273 is fixedly mounted on the side wall of the first adjustment plate 271, an end of the first spring 273 is fixedly mounted on the side wall of the first circular block 266, a second interface 272 is arranged inside the first adjustment plate 271, the second interface 272 is connected to the center groove 275, and the second interface 272 is in contact and extrusion with the first joint 13.

[0040] It should be noted that the sphere 274 enables the second interface 272 to adapt to the inclination angle of the interface on the first joint 13 when it contacts the interface on the first joint 13. At the same time, the center groove 275 enables the second interface 272 and the first adjustment plate 271 to be concentric with the trachea outlet 262 when the first adjustment plate 271 is in a normal state. The diameter of the center groove 275 is smaller than the diameter of the trachea outlet 262, and the inner wall of the trachea outlet 262 is in a sealed connection with the outer wall of the sphere 274, so that during inflation, the gas can enter the interior of the second interface 272 through the trachea outlet 262 and the center groove 275, and then enter the interface on the first joint 13.

[0041] like Figures 5 to 7 As shown, the locking device 3 includes a locking extrusion member 31 rotatably installed inside the supporting protrusion 265, and the locking extrusion member 31 rotates to clamp the ball 274. The end of the locking extrusion member 31 is connected to the first transmission member 32, and the outer wall of the first support frame 21 is symmetrically installed with a U-shaped support frame 33, and the U-shaped support frame 33 is used to limit the first transmission member 32. The first support frame 21 is provided with a first groove 211, and the locking transmission member 34 is slidably installed inside the first groove 211. The end of the locking transmission member 34 is fixedly connected to the second support frame 22, and the locking transmission member 34 moves to drive the first transmission member 32 to rise, and the rise of the first transmission member 32 is used to drive the locking extrusion member 31 to clamp the ball 274.

[0042] It should be noted that when the second support frame 22 moves and drives the locking transmission member 34 to move in the direction away from the inflation tube 15, the first transmission member 32 can be lifted up, and the rise of the first transmission member 32 can drive the locking extrusion member 31 to rotate, thereby clamping and limiting the ball 274. The locking extrusion member 31 includes a first locking block 311 rotatably mounted on the support protrusion 265. The first locking block 311 itself has the effect of a telescopic rod. When the first transmission member 32 is raised and lowered, it drives the locking extrusion member 31 to clamp the ball 274. The first locking block 311 can be adaptively retracted and retracted. When rotating, the distance between the center position of the locking transmission member 34 and the center position of the ball 274 remains unchanged, thereby preventing the ball 274 from rotating and shaking during inflation.

[0043] like Figures 5 to 7 As shown, the locking extrusion member 31 includes a first locking block 311 rotatably mounted at the end of the supporting protrusion 265, and the first locking block 311 can be a telescopic rod. A first rotating block 312 is rotatably mounted on one end of the first locking block 311 close to the sphere 274, and a first locking rod 313 is fixedly mounted on the bottom end of the first rotating block 312. A hole is opened inside the first circular block 266, so that the first locking rod 313 slides inside the first circular block 266, and the first locking rod 313 slides inside the first circular block 266 to clamp and limit the sphere 274.

[0044] It should be noted that the first locking block 311 is a telescopic rod that can be adaptively extended and retracted. Therefore, when the locking transmission member 34 lifts the first transmission member 32, under the action of the support protrusion 265, the first rotating block 312 and the first locking rod 313 move toward the center of the sphere 274, thereby clamping and locking the sphere 274 to prevent the sphere 274 from moving and rotating after installation, thereby improving safety during inflation, preventing air leakage during inflation, and preventing the opening on the second interface 272 and the first joint 13 from being unsealed.

[0045] like Figure 6 to Figure 7 As shown, the first transmission member 32 includes a first locking block 311 at one end away from the sphere 274, on which a second rotating block 321 is rotatably mounted; a first sliding rod 322 is fixedly mounted on the top of the second rotating block 321; a second spring 323 is arranged on the outside of the first sliding rod 322; the second spring 323 is concentric with the first sliding rod 322; a first extrusion column 324 is fixedly mounted on the bottom end of the second rotating block 321; the first extrusion column 324 is in contact with the locking transmission member 34; and the first sliding rod 322 slides inside the U-shaped support frame 33.

[0046] It should be noted that the second rotating block 321 is rotatably installed at the end of the first locking block 311, so that when the locking transmission member 34 moves, the first extrusion column 324 is lifted up, and the rise of the first extrusion column 324 drives the end of the locking extrusion member 31 and the first slide rod 322 to rise, so that the first slide rod 322 slides inside the U-shaped support frame 33, and the first locking rod 313 can clamp the ball 274, thereby preventing the ball 274 from moving during inflation and causing leakage.

[0047] like Figure 6 to Figure 7 As shown, the locking transmission member 34 includes a second sliding column 341 slidably installed inside the first support frame 21, the outer wall of the second sliding column 341 is fixedly installed with a first limiting plate 343, the side wall of the first limiting plate 343 is fixedly installed with a third spring 344, the third spring 344 is concentric with the second sliding column 341, the end of the second sliding column 341 is fixedly installed with the second support frame 22, the outer wall of the second sliding column 341 is fixedly installed with a first protrusion 342, and the first protrusion 342 moves to lift the first extrusion column 324.

[0048] It should be noted that the end of the first extrusion column 324 is in contact with the second sliding column 341. When the second sliding column 341 moves under the action of the second support frame 22, it drives the first protrusion 342 on the outer wall of the second sliding column 341 to move. When the first protrusion 342 moves to contact the first extrusion column 324, the first protrusion 342 can lift the first extrusion column 324, thereby clamping the ball 274. After inflation is completed, the second sliding column 341 and the second support frame 22 can be reset by the third spring 344 and the first limit plate 343, so as to carry out the next round of inflation.

[0049] like Figure 4 As shown, the diameter of the central groove 275 is smaller than the diameter of the trachea outlet 262 , and the central groove 275 is always in a state of being fully connected with the trachea outlet 262 when moving.

[0050] It should be noted that the diameter of the center groove 275 is smaller than the diameter of the trachea outlet 262, so that when the sphere 274 moves inside the first annular block 266, the center groove 275 will not exceed the area surrounded by the trachea outlet 262, so that when the center groove 275 moves, it is always in a state of being fully connected with the trachea outlet 262.

[0051] A method for inflating a gas cylinder in a container, the method adopts the above-mentioned inflating device for a gas cylinder in a container, and comprises the following steps:

[0052] Step 1: vent the multiple first gas tanks 12 used, put them in a heated vacuum cabinet after the pressure inside the tanks is released to the normal pressure, connect them through a clamp, open all the gas cylinder valves, turn on the vacuum pump, control the temperature at 100°C, and evacuate for one hour. When the value of the digital vacuum gauge reaches 0.5 Pa, it is qualified. Close all the first gas tanks 12 and the second gas tanks 14, place them at room temperature, connect the first gas tanks 12 to the container grid, and connect all the first gas tanks 12 through the gas manifold;

[0053] Step 2: Use an explosion-proof forklift to transport the container to the equipment side, connect it to the valve through a clamp, and an additional first gas tank 12 of the same volume is required as a reference tank, that is, the first gas tank 12 is the reference tank, and the second gas tank 14 is the gas tank, which are respectively connected to the gas filling detector 1. First, the electronic scale 11 on the reference tank is cleared, and then the first gas tank 12 is placed on the electronic scale 11. Then, the first connector 13 of the electronic scale 11 is connected to the gas filling tightening device 2, and the direction fixing member 26 is connected to the direction adjusting member 26. The first extrusion block 25 is engaged with the first support frame 22 so that the direction adjusting member 27 is squeezed with the first joint 13 to prevent the direction adjusting member 27 and the first joint 13 from leaking during inflation. The handle 24 is held and rotated so that the first extrusion block 25 is squeezed toward the back of the first joint 13 to clamp the first joint 13. The first extrusion block 25 drives the second support frame 22 to move when moving and clamping, so that the locking device 3 locks the direction adjusting member 27 to prevent the direction adjusting member 27 from moving during inflation.

[0054] Step 3. When the value on the vacuum gauge is one Pa, open the first connector 13 on the first gas filling tank 12 and measure the vacuum degree. When the value on the vacuum gauge remains the same or decreases, it is considered qualified. Then, measure the vacuum degrees of all the first gas filling tanks 12 in turn by the same operation. When all the first gas filling tanks 12 are qualified, open the valves of all the first gas filling tanks 12, and observe the weight change of the balance by controlling the valve on the raw gas panel. The flow rate is controlled at one gram per three seconds. Wait for half an hour so that the gas pressure in the bottle is consistent, record the pressure P in the pipeline, close the valve of the second gas filling tank 14, and press the gas pressure in the pipeline to 400. Empty the pipeline by force to 1 Pa, close the valve, record the weight, which is the weight of the first component, replace the second gas tank 14, and perform vacuum treatment on the pipeline in the same way as above. After the treatment, open the balance gas valve, increase the pressure in the pipeline to P, continue to control the flow rate when adding in the same way as above, and when the balance weight reaches the required weight, close all the first gas tanks 12 and the second gas tanks 14, release the pressure in the pipeline, weigh the first gas tank 12, and calculate the concentration of each substance in the first gas tank 12, which is regarded as the concentration of all gas cylinders.
