Description

Technical Field

[0001] This utility model relates to the technical field of gas cylinder filling devices, specifically to a carbon dioxide-argon mixed gas cylinder filling device. Background Technology

[0002] The carbon dioxide-argon mixed gas cylinder filling device is a specialized piece of equipment used to accurately mix carbon dioxide and argon in a preset ratio and safely and efficiently fill the cylinder. It is mainly used in the mixed gas production process and solves the problem of inaccurate gas mixing ratio during the carbon dioxide-argon mixed filling process, which leads to fluctuations in purity.

[0003] However, in the actual filling process, the gas cylinder's vent pipe is usually connected to one gas. Due to the mixed filling of the two gases, when the gas is filled into the cylinder, one gas will be filled into the cylinder first, and then the other gas will be filled in. Because carbon dioxide and argon have significantly different physical properties, they will interfere with each other during the filling process, which will lead to measurement deviation and inaccurate gas ratio. Utility Model Content

[0004] This invention proposes a carbon dioxide-argon mixed gas cylinder filling device, which solves the problem in the prior art that the gas ratio is easily inaccurate when filling carbon dioxide and argon one by one.

[0005] The technical solution of this utility model is as follows:

[0006] A carbon dioxide-argon mixed gas cylinder filling device includes two cylinders placed on a base plate, and further includes: a first vent pipe, a second vent pipe, a mixing component, a gas dispersing component, and a stabilizing component. The first vent pipe and the second vent pipe are both disposed on the mixing component, which is disposed on the base plate. Two gas dispersing components are disposed on the mixing component, and two stabilizing components are disposed on the base plate for stabilizing the cylinders.

[0007] Furthermore, the mixing assembly includes: a support rod, a connecting pipe, and a mixing pipe. Two of the support rods are fixedly installed on the base plate, the connecting pipe is fixedly installed on the support rod, and the mixing pipe is connected to the side of the connecting pipe.

[0008] Furthermore, the gas dispersing assembly includes a U-shaped tube and a vertical tube, the vertical tube being connected to the bottom end of the mixing tube, the top end of the U-shaped tube being connected to the bottom end of the vertical tube, and the bottom end of the U-shaped tube being connected to the top end of the gas cylinder.

[0009] Furthermore, the stabilizing component includes: a support cover, a reciprocating screw, a motor, a first stabilizing ring, and a sliding component. Two support covers are fixedly installed on the base plate. The reciprocating screw is rotatably installed inside one of the support covers, and a matching crescent-shaped slider is installed on the reciprocating screw. The motor is installed on the side of the support cover, and the output end of the motor is coaxially connected to the reciprocating screw. The first stabilizing ring is fixedly installed on the crescent-shaped slider.

[0010] Furthermore, the sliding assembly includes: a sliding rod, a sliding block, a second stabilizing ring, and a connecting rod. The sliding rod is fixedly installed inside another support cover, the sliding block is slidably installed on the sliding rod, the second stabilizing ring is fixedly installed on the sliding block, and the connecting rod is fixedly installed between the second stabilizing ring and the first stabilizing ring.

[0011] Furthermore, safety valves and pressure gauges are installed on the first vent pipe, the second vent pipe, and the mixing pipe.

[0012] The working principle and beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, when carbon dioxide and argon are introduced, carbon dioxide and argon can be introduced into the mixing component through the first and second gas inlet pipes, respectively. Then, the two gases are mixed through the mixing component, thereby improving the uniformity of premixing, reducing stratification inside the cylinder, and the mixed gas can pass through the gas dispersing component when it is introduced into the cylinder, which can also increase the uniformity of the mixed gas.

[0014] 2. In this utility model, when the mixed gas is introduced into the steel cylinder, the steel cylinder can be clamped and stabilized by the stabilizing component, so as to avoid the steel cylinder shaking and causing internal pressure fluctuations, which would affect the metering accuracy of the mixed gas.

[0015] In summary, this device, through the cooperation of the first ventilation pipe, the second ventilation pipe, the mixing component, the gas dispersing component, and the stabilizing component, can mix carbon dioxide and argon when they are introduced into the cylinder, thus avoiding the problem of inaccurate gas ratios in the later stages.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-4 As shown in the figure, this embodiment proposes a carbon dioxide-argon mixed gas cylinder filling device, including two cylinders 2 placed on a base plate 1, and also including a first gas inlet pipe 3, a second gas inlet pipe 4, a mixing component, a gas dispersing component, and a stabilizing component. The first gas inlet pipe 3 and the second gas inlet pipe 4 are both arranged on the mixing component, which is arranged on the base plate 1. There are two gas dispersing components, which are arranged on the mixing component. There are two stabilizing components, which are arranged on the base plate 1, for stabilizing the cylinders 2.

[0024] like Figure 2 and Figure 4As shown, when carbon dioxide and argon are introduced into cylinder 2, carbon dioxide is first introduced through vent pipe 3, and then argon is introduced through vent pipe 4. The two gases are then mixed evenly through a mixing assembly, which includes support rods 5, connecting pipes 6, and mixing pipes 7. Two support rods 5 are fixedly installed on the base plate 1, and the connecting pipes 6 are fixedly installed on the support rods 5. The mixing pipes 7 are connected to the side of the connecting pipes 6. Specifically, after the two gases pass through the connecting pipes 6, they enter the mixing pipes 7 for mixing. When entering cylinder 2, the mixed gases can be dispersed again through a gas dispersing assembly. The gas is dispersed into the cylinder 2. The gas dispersion assembly includes a U-shaped tube 8 and a vertical tube 9. The vertical tube 9 is connected to the bottom end of the mixing tube 7, and the top end of the U-shaped tube 8 is connected to the bottom end of the vertical tube 9. The bottom end of the U-shaped tube 8 is also connected to the top end of the cylinder 2. Specifically, the two mixed gases enter the U-shaped tube 8 through the vertical tube 9. The U-shaped tube 8 has two outlets, which allows the mixed gases to be dispersed into two paths into the cylinder 2. Safety valves 18 and pressure gauges 19 are installed on the first vent pipe 3, the second vent pipe 4, and the mixing tube 7. The safety valves 18 can be opened to allow gas flow, and the internal pressure can be observed by observing the pressure gauges 19.

[0025] like Figure 3 As shown, when gas is introduced, the two gas cylinders 2 can be clamped and stabilized by a stabilizing assembly. The stabilizing assembly includes a support cover 10, a reciprocating screw 11, a motor 12, a stabilizing ring 13, and a sliding assembly. Two support covers 10 are fixedly installed on the base plate 1. The reciprocating screw 11 is rotatably installed inside one of the support covers 10, and a matching crescent-shaped slider 20 is installed on the reciprocating screw 11. The motor 12 is installed on the side of the support cover 10, and the output end of the motor 12 is coaxially connected to the reciprocating screw 11. The stabilizing ring 13 is fixedly installed on the crescent-shaped slider 20. The sliding assembly includes a sliding rod 14, a sliding block 15, a second stabilizing ring 16, and a connecting rod 17. The sliding rod 14 is fixedly installed inside the other support cover 10, the sliding block 15 is slidably installed on the sliding rod 14, the second stabilizing ring 16 is fixedly installed on the sliding block 15, and a connecting rod 17 is fixedly installed between the second stabilizing ring 16 and the first stabilizing ring 13.

[0026] Specifically, the motor 12 is started, and its output drives the reciprocating screw 11 to rotate within the support cover 10. It should be noted that the shape of the crescent-shaped slider 20 matches the helical groove of the reciprocating screw 11. When the reciprocating screw 11 rotates, the sidewall of the helical groove exerts an axial thrust on the crescent-shaped slider 20 embedded within it. This allows the crescent-shaped slider 20 to move along the axial trajectory of the reciprocating screw 11, thus performing forward and backward movement. When the crescent-shaped slider 20 reaches the end of the reciprocating screw 11, it smoothly transitions to the reverse helical groove, thereby achieving reciprocating movement. This is well-known technology and will not be elaborated further. Furthermore, the crescent-shaped slider... Block 20 moves the first stabilizing ring 13 forward to fit the side of the cylinder 2, and under the connection of the connecting rod 17, it moves the second stabilizing ring 16 at the other end forward, and moves the sliding block 15 to slide synchronously on the sliding rod 14, which can also limit the rotation of the crescent slider 20. Then, the second stabilizing ring 16 moves forward to fit the surface of another cylinder 2. Then, the two cylinders 2 are respectively clamped and fixed by the two first stabilizing rings 13 and the two second stabilizing rings 16 to prevent shaking. It should be added that the inner sidewalls of the first stabilizing ring 13 and the second stabilizing ring 16 fit against the outer sidewall of the cylinder 2, and the inner sidewalls of the first stabilizing ring 13 and the second stabilizing ring 16 are equipped with rubber pads.

[0027] Working principle: When carbon dioxide and argon are mixed and filled into cylinder 2, carbon dioxide is first introduced through vent pipe 3, and then argon is introduced through vent pipe 4. After passing through connecting pipe 6, the two gases enter mixing pipe 7 for mixing. When entering cylinder 2, the two mixed gases enter U-shaped pipe 8 through vertical pipe 9. U-shaped pipe 8 has two outlets, which can disperse the mixed gas into two paths entering cylinder 2. Safety valve 18 and pressure gauge 19 are installed on vent pipe 3, vent pipe 4, and mixing pipe 7. Safety valve 18 can be opened to allow gas flow, and internal pressure can be observed by observing pressure gauge 19.

[0028] During filling, the motor 12 can be started. The output end of the motor 12 drives the reciprocating screw 11 to rotate inside the support cover 10. The crescent slider 20 can move along the axial trajectory of the reciprocating screw 11, thereby moving back and forth. The crescent slider 20 drives the first stabilizing ring 13 to move forward to fit the side of the steel cylinder 2. Under the connection of the connecting rod 17, it drives the second stabilizing ring 16 at the other end to move forward, and drives the sliding block 15 to slide synchronously on the sliding rod 14. It can also limit the rotation of the crescent slider 20. Then, the second stabilizing ring 16 moves forward to fit the surface of another steel cylinder 2. Then, the two steel cylinders 2 are clamped and fixed by the two first stabilizing rings 13 and the two second stabilizing rings 16 respectively to prevent shaking.

[0029] It should be added that the motor 12 is powered by a battery or generator 12, and the gas flows through the pressure difference between the gas source and the gas cylinder 2. This pressure difference can be provided by the gas source itself or generated by the compressor, so that the gas pressure in the gas cylinder 2 is lower than the gas pressure of the gas source, thereby causing the gas to flow from the high-pressure area to the low-pressure area. In addition, sealing rings are installed at all the penetrations of this device to prevent gas leakage, and a telescopic protective cover is installed on the outside of the reciprocating screw 11 to protect the reciprocating screw 11.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
