Description

Technical Field

[0001] This utility model belongs to the field of gas mixing technology, and specifically relates to a novel standard mixed gas mixing device. Background Technology

[0002] In the production process of standard mixed gases, the uniformity of the standard mixed gases is the foundation of their accuracy and reliability. If the gas is not distributed uniformly in the container, the concentration of gas components in some areas may be too high or too low, thereby affecting the overall performance of the standard gas and causing deviations in the measurement results, thus affecting the accuracy and reliability of the data. Therefore, homogenization treatment during the preparation of standard mixed gases is an important measure to ensure gas uniformity, accuracy and reliability.

[0003] Traditional cylinder rolling machines achieve automatic rolling and mixing of gas cylinders through mechanical means, improving the efficiency of gas mixing. Current usage typically involves placing the gas cylinders directly between the rotating shafts of the cylinder rolling machine. A motor drives the rotating shafts to roll, and the rollers on the shafts rotate, causing the gas cylinders to rotate and thus mixing the various gases inside the cylinders evenly.

[0004] However, existing cylinder rolling machines have problems such as fixed size, inability to adjust according to different gas cylinder packaging specifications, difficulty in fixing the gas cylinder body, risk of falling off during rolling, and inability to adjust the speed, resulting in long mixing time for difficult-to-mix gas components and low work efficiency.

[0040] Through the above technical solution, an arc-shaped rubber sleeve 6 is embedded in the groove on the first fixed baffle 11.

In this way, when the gas cylinder 2 is rolled, the cover of the gas cylinder 2 can be placed in the arc-shaped rubber sleeve 6 to achieve the function of limiting the gas cylinder 2.

[0043] In this embodiment, a speed-changing display screen 7 is connected to the outer wall of the support platform 1 to display the rotation speed of the first drive motor; a speed-changing button is also provided on the outer wall of the support platform 1.

[0044] Through the above technical solution, the rotation speed of the first drive unit 13 can be set by rotating the speed change knob 8 according to the different components of the mixed gas in the bottle, thereby achieving rapid mixing of mixed gases that are difficult to mix, thus saving time and improving work efficiency.

[0045] In this embodiment, the second limiting component includes two sliding rails 15 and a telescopic plate 5; the two sliding rails 15 are respectively disposed at both ends of the driven shaft 3 in the radial direction, and the two ends of the sliding rails 15 are respectively fixedly connected to the first fixed baffle 11 and the second fixed baffle 12; the telescopic plate 5 is slidably connected to the sliding rails 15 through pulleys; the telescopic plate 5 is provided with a first through hole; the drive shaft 4 passes through the first through hole;
