Description

Technical Field

[0001] The present application relates to standard gas preparation technology, and in particular to a gas cylinder mixing device for standard gas preparation. Background Art

[0002] Standard gas is a term in the gas industry, referring to a measurement standard with uniform concentration, good stability and accurate value. They have the basic functions of reproducing, preserving and transferring values. In the fields of physical, chemical, biological and engineering measurement, they are widely used to calibrate measuring instruments and measurement processes, evaluate the accuracy of measurement methods, test the detection capabilities of testing laboratories, and determine the characteristic values ​​of materials or products. Standard gases are divided into binary, ternary and multi-element standard gases, and can be divided into gas alarm, power energy, instrumentation, etc. according to their uses.

[0003] However, due to the differences in diffusion capacity between different gas molecules and the adsorption and desorption equilibrium process between the inner wall of the gas cylinder and the gas components, the standard gas often has an uneven distribution problem after being filled into the gas cylinder. This unevenness will lead to errors in the measurement results and affect the use of the standard gas.

[0004] In the prior art, the mixing of standard gases in gas cylinders is mostly done by natural diffusion or mechanical rolling. Although the natural diffusion method is simple, it takes a long time to reach a uniform state and is inefficient; while the mechanical rolling method requires special equipment, has poor applicability to gas cylinders of different specifications, and has a long production cycle. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] As attached Figure 1 -Attached Figure 3 As shown, a gas cylinder mixing device for preparing standard gas comprises a base frame 1, the base frame 1 is provided with a flippable mounting frame 2, a driving shaft 3 and a driven shaft 4 located on both sides of the driving shaft 3 are rotatably provided on the mounting frame 2, the driving shaft 3 is driven by a driving motor 5 arranged on the mounting frame 2, a plurality of driving rubber rollers 6 are provided on the driving shaft 3, a plurality of driven rubber rollers 7 corresponding to the driving rubber rollers 6 are provided on the driven shaft 4, and a rolling area for placing gas cylinders is formed between the driving rubber rollers 6 and the adjacent driven rubber rollers 7.

[0020] In one embodiment, a cylinder 8 is hinged on the base frame 1, and the end of the piston rod of the cylinder 8 is hinged to the bottom of the mounting frame 2. A support frame 9 for supporting the mounting frame 2 is provided on one side of the base frame 1. This design makes the turning of the mounting frame 2 simple and efficient. When the piston rod of the cylinder 8 is extended, it will push the mounting frame 2 to gradually turn from the vertical direction to the horizontal state, thereby facilitating the placement and mixing of the gas cylinder. After the turning is completed, the mounting frame 2 is supported by the support frame 9 on one side of the base frame 1 to ensure the stability of the entire mixing process.

[0021] In one embodiment, columns 10 are further provided on both sides of the mounting frame 2, and locking rings 11 are provided on the columns 10, and U-shaped pressure rods 12 are inserted between the locking rings 11 on both sides. This design makes the fixing of the gas cylinders convenient and reliable. By inserting the U-shaped pressure rods 12 into the locking rings 11, multiple gas cylinders can be easily pressed between the active rubber roller 6 and the driven rubber roller 7, respectively, to ensure that the gas cylinders will not move or slip during the mixing process. This fixing method is simple and effective, and improves the accuracy and safety of the mixing operation.

[0022] In one embodiment, guardrails 13 are further provided on both sides of the mounting frame 2. The function of the guardrails 13 is to prevent personnel from accidentally contacting the rotating gas cylinders or rubber rollers during operation, thereby avoiding possible injury accidents. At the same time, the guardrails 13 can also effectively prevent the gas cylinders from falling due to vibration during the mixing process, thereby enhancing the safety of the entire operation process.

[0023] In one embodiment, a support plate 14 is provided at one end of the mounting frame 2 away from the driving motor 5, and a positioning rubber pad 15 corresponding to the position of the rolling zone is provided on the support plate 14. This design makes the placement of the gas cylinder more accurate and stable. The positioning rubber pad 15 not only provides a support point for the placement of the gas cylinder, but also prevents the gas cylinder from sliding or shaking during the placement process. Through the auxiliary positioning of the support plate 14 and the positioning rubber pad 15, it can be ensured that each gas cylinder is accurately placed in the rolling zone, laying a good foundation for the subsequent mixing operation.

[0024] In one embodiment, the driven shaft 4 is fixed to the mounting frame 2 through the mounting seat 16, and the driven shaft and the mounting seat 16 are rotatably connected through a bearing. The mounting frame 2 is provided with a strip hole 17 corresponding to the position of the mounting seat 16, and the mounting seat 16 is fixed at the strip hole 17 through an adjusting bolt 18. This design allows the position of the driven shaft 4 and the driven rubber roller 7 thereon to be flexibly adjusted according to the size of the gas cylinder. By loosening the adjusting bolt 18 and moving the position of the mounting seat 16 in the strip hole 17, the distance between the driven rubber roller 7 and the active rubber roller 6 can be easily adjusted to adapt to gas cylinders of different sizes, ensuring the smooth progress of the mixing operation.

[0025] Working principle: First, adjust the mounting frame 2 to a vertical direction, and then place the gas cylinder containing the standard gas to be mixed on the positioning rubber pad 15 on the support plate 14 to ensure that the gas cylinder is stable and accurately positioned.

[0026] Next, insert the U-shaped pressure rod 12 into the locking rings 11 on both sides of the mounting frame 2, so that the U-shaped pressure rod 12 presses the multiple gas cylinders respectively in the rolling area formed between the corresponding active rubber roller 6 and the driven rubber roller 7 to ensure that the gas cylinders will not move or slip during the mixing process.

[0027] Then, the cylinder 8 is started, and the piston rod of the cylinder 8 is extended, pushing the mounting frame 2 to gradually turn over to a horizontal state, and supported by the supporting frame 9. At this time, the gas cylinder is in a position ready for mixing.

[0028] Finally, the driving motor 5 is started, and the driving motor 5 drives the driving shaft 3 and the driving rubber roller 6 thereon to rotate. The rotation of the driving rubber roller 6 will drive the gas cylinder to rotate at a uniform speed, and at the same time, the rotation of the gas cylinder will also cause the driven rubber roller 7 to rotate accordingly, thereby ensuring that the rotation of the gas cylinder is stable and uniform. During the mixing process, the position of the driven shaft 4 and the driven rubber roller 7 thereon can be flexibly adjusted by adjusting the bolt 18 according to the size of the gas cylinder to adapt to gas cylinders of different sizes.

[0029] Through the above steps, the equipment can be used to achieve the mixing operation of gas cylinders for standard gas preparation, ensuring uniform mixing of gases and improving preparation efficiency.

Although the embodiments of the present application are described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
