Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of gas sample proportioning devices, and more specifically, particularly relates to an automatic proportioning device for mixed gas sample proportioning. Background Art
[0002] Gas automatic proportioning and mixing device is an advanced technology, which is widely used in laboratory research, industrial production, medical treatment and environmental monitoring. It ensures accurate gas mixing ratio by automatically controlling and adjusting the flow of different gases. However, in terms of energy consumption, some highly automated devices usually need to maintain complex operating states, involving a large number of mechanical and electronic components, resulting in relatively high energy consumption, and some devices may face unsatisfactory gas mixing effects in actual operation, which may affect the stability of industrial production or the accuracy of medical applications. Therefore, there is an urgent need for a gas automatic proportioning and mixing device with low efficiency and uniform gas mixing.

[0007] As a further technical solution, the oblique exhaust plates present an alternating oblique flow guide, and this design can extend the path of gas flow and allow the gas to be alternated more fully.
[0008] A further technical solution is that first ventilation holes are symmetrically provided on both sides of the upper ventilation plate, the first ventilation holes are located directly below both sides of the inclined exhaust plate, and the first ventilation holes are through holes provided in a rectangular array, which can prolong the gas mixing time.
[0009] According to a further technical solution, a second ventilation hole is provided in the middle of the lower ventilation plate. The second ventilation hole drives the spiral pneumatic blades to rotate when exhausting air upward, and the spiral pneumatic blades further mix the gas when rotating.
[0010] According to a further technical solution, an inclined baffle provided below the lower ventilation plate is formed to be connected with both sides of the second ventilation holes.
[0011] According to a further technical solution, the oblique baffles on both sides form an air inlet cavity, and the oblique blades are located inside the air inlet cavity when rotating.
[0012] A further technical solution is that a transmission motor is provided inside the transmission casing, an output end of the transmission motor is fixedly connected to the transmission shaft, fixed feet are provided in a rectangular array around the transmission casing, a bottom fixing frame is provided between the fixed feet, the bottom fixing frame is fixedly connected to the inner side of the fixed feet, and the intersection of the bottom fixing frame is located at the bottom of the transmission casing.
[0013] According to a further technical solution, an instrument panel is installed on the surface of the front panel of the device, a barometer and a safety device are provided on the surface of the instrument panel, and the safety device is located below the barometer.

[0015] Compared with the prior art, the utility model has the following beneficial effects:
[0016] By having a transmission motor inside the transmission housing, the stirring motor can ensure that the gas is evenly mixed in the matching device. This is very important for substances that need to be evenly distributed in the gas, such as dissolved gases, catalysts, etc., and the stirring motor helps to accelerate the reaction rate by causing the gas to contact more fully with other reactants. During the reaction, the stirring motor can help maintain the temperature uniformity of the device. By mixing the gas, the heat can be better dispersed or evenly distributed, helping to avoid problems caused by temperature gradients.
[0017] The spiral pneumatic blades can be used to stir the gas again, so that the gas is more evenly distributed throughout the mixing device, which is very important for ensuring the uniformity of the components in the mixed gas, especially in chemical reactions, biological reactions, and other processes that require precise proportions. The pneumatic rotary blade design can reduce or eliminate dead zones in the mixer, that is, areas that are difficult to mix. This helps to ensure that the entire mixing process is more uniform and prevents insufficient mixing. Pneumatic rotary blades can usually provide efficient stirring effects with low power consumption, which may be more energy-efficient than some traditional stirring methods.
[0018] By cooperating with the first ventilation hole and the inclined exhaust plate, the gas can diffuse to both sides when it reaches the bottom of the inclined exhaust plate and meet at the inclined insertion so that the gas can be blended again. The inclined guide plate can help stabilize the airflow direction and reduce the possibility of gas drift. Drift may cause changes in the mixing ratio. By reasonably designing the relative position of the guide plate and the exhaust hole, the interference of external factors on the mixed gas can be reduced, thereby improving the stability of the mixing.
