[0002] Standard mixed gases refer to gases that are mixed in a certain proportion of two or more gases. They have wide applications in industrial production, laboratory research and environmental monitoring.

[0003] A standard gas mixing device is a specialized device for mixing different gases. This device can rotate a gas cylinder containing multiple gases to quickly mix the various gases inside the cylinder, thereby improving the efficiency of gas mixture preparation.

[0004] However, existing standard gas mixing devices have low mixing efficiency, and when mixing gas cylinders containing liquid oxygen, they cannot accelerate the vaporization of liquid oxygen. They can only wait for the liquid oxygen to vaporize before mixing the vaporized oxygen with other gases, resulting in low efficiency. Therefore, they do not meet the current requirements. To address this, we propose a standard gas mixing device. Utility Model Content

[0005] The purpose of this invention is to provide a standard mixed gas mixing device to solve the problems mentioned in the background art, such as low mixing efficiency of existing standard mixed gas mixing devices, and the inability to accelerate the vaporization rate of liquid oxygen when mixing gas cylinders containing liquid oxygen. The vaporized oxygen can only be mixed with other gases after the liquid oxygen has vaporized, resulting in low efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a standard mixed gas mixing device, comprising a bottom shell of the mixing device, a mixing device cover mounted on the upper end face of the bottom shell of the mixing device via a rotating shaft, and multiple heating lamps fixedly mounted on the inner wall of the mixing device cover;

A placement frame is fixedly installed at the middle position of the upper end face of the rotating table. A mixed gas cylinder rolling roller is provided on both sides inside the placement frame. A roller shaft is connected to the axis of the mixed gas cylinder rolling roller. A first gear is fixedly sleeved on the outer surface of the front end of the second roller shaft from the left. The first gear meshes with a second gear. A long rotating shaft is connected to the axis of the second gear. A third gear is fixedly sleeved on one side of the outer surface of the long rotating shaft. A large upper gear ring fixed inside the bottom shell of the mixing device is meshed on the lower end face of the third gear.

[0008] Preferably, a fixing ring is fixedly sleeved on the lower side of the outer surface of the bottom shell of the mixing device, and the outer surface of the fixing ring is provided with multiple fixing through holes.

[0009] Preferably, a handle is fixedly provided on one side of the outer surface of the mixing device cover, and the mixing device cover and the handle are fixed together by screws.

[0010] Preferably, a control panel is installed on one side of the outer surface of the bottom shell of the mixing device, and the control panel is electrically connected to the heating lamp and the mixing motor.

[0011] Preferably, both ends of the roller shaft are located inside the placement frame, and the roller shaft located inside the placement frame is connected to the placement frame by roller bearings.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a mixing motor to drive the mixed gas bottle to rotate around the transmission shaft while the mixing motor drives the mixed gas bottle to roll. This driving structure increases the variation range of the gas inside the mixed gas bottle, thereby improving its mixing efficiency. The above technical solution improves the preparation efficiency of mixed gas.

[0016] 2. This utility model improves the mixing efficiency of the equipment for mixed gas cylinders containing liquid oxygen by using a heating lamp when the mixed gas cylinder contains liquid oxygen.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The mixing motor 5 (model DM542), the first gear 11 (model M16), and the mixed gas cylinder 10 (model 000215) mentioned in this utility model can be obtained from the market or through private customization.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, one embodiment of the present invention is a standard mixed gas mixing device, including a bottom shell 1 of the mixing device, a mixing device cover 3 installed on the upper end face of the bottom shell 1 of the mixing device via a rotating shaft, and a plurality of heating lamps 4 fixedly installed on the inner wall of the mixing device cover 3.

[0025] A mixing motor 5 is fixedly installed on the lower side inside the bottom shell 1 of the mixing device. The output shaft of the mixing motor 5 is connected to a transmission shaft 6 via a coupling. A rotating table 7 is connected to the upper end face of the transmission shaft 6. The rotating table 7 is connected to the bottom shell 1 of the mixing device via roller bearings. A placement frame 8 is fixedly installed at the middle position of the upper end face of the rotating table 7. A mixed gas cylinder rolling roller 9 is provided on both sides inside the placement frame 8. A roller shaft 17 is connected to the axis of the mixed gas cylinder rolling roller 9. A first gear 11 is fixedly sleeved on the outer surface of the front end of the second roller shaft 17 from the left. The first gear 11 meshes with a second gear 12. A long rotating shaft 13 is connected to the axis of the second gear 12. A third gear 14 is fixedly sleeved on one side of the outer surface of the long rotating shaft 13. A large upper gear ring 15 fixed inside the bottom shell 1 of the mixing device is meshed on the lower end face of the third gear 14.

[0026] As a preferred technical solution in this embodiment, such as Figure 1 As shown, a fixing ring 16 is fixedly sleeved on the lower side of the outer surface of the bottom shell 1 of the mixing device, and the outer surface of the fixing ring 16 is provided with multiple fixing through holes; before using the equipment, the equipment is fixed in a certain position by the fixing ring 16 to prevent the equipment from swinging due to the rotational force during operation.

[0027] A control panel 2 is installed on one side of the outer surface of the bottom shell 1 of the mixing device, and the control panel 2 is electrically connected to the heating lamp 4 and the mixing motor 5; the heating lamp 4 and the mixing motor 5 located inside the device can be controlled through the control panel 2.

[0028] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 4 As shown, a handle is fixedly provided on one side of the outer surface of the mixing device cover 3, and the mixing device cover 3 and the handle are fixed together by screws; a mixing gas bottle 10 is provided between the two mixing gas bottle rolling rollers 9, and the mixing gas bottle 10 contains liquid oxygen; before using the equipment, liquid oxygen and the gas to be mixed with liquid oxygen are added to the mixing gas bottle 10, and then the mixing device cover 3 is opened by the handle, and the mixing gas bottle 10 is placed between the two mixing gas bottle rolling rollers 9. After the mixing gas bottle 10 is placed, the mixing device cover 3 is closed, and then the mixing motor 5 is started. The mixing motor 5 can drive the rotating table 7 connected to it through the transmission shaft 6 to rotate. When the rotating table 7 rotates, the placement frame 8 fixed on the upper end face of the rotating table 7 and the mixing gas bottle 10 placed on the two mixing gas bottle rolling rollers 9 located on both sides inside the placement frame 8 will rotate together.

[0029] During the rotation of the rotary table 7, the third gear 14 will roll along the upper end face of the large upper gear ring 15. During the rolling of the third gear 14, the long rotating shaft 13 connected to the axis of the third gear 14 and the second gear 12 fixedly sleeved on the outer surface of the long rotating shaft 13 will rotate together. The rotating second gear 12 can drive the first gear 11 meshing with it and the roller shaft 17 connected to the axis of the first gear 11 to rotate. When the roller shaft 17 rotates, the mixed gas cylinder rolling roller 9 fixedly sleeved on the outer surface of the roller shaft 17 will rotate together. When one of the mixed gas cylinder rolling rollers 9 rotates, it will drive the mixed gas cylinder 10 that is in contact with it to rotate. Through this embodiment, the mixed gas cylinder 10 can be rotated around the transmission shaft 6 while being driven to roll, thereby increasing the variation range of the gas inside the mixed gas cylinder 10 and improving the preparation efficiency of the mixed gas.

[0030] When the mixed gas cylinder 10 contains liquid oxygen, the mixed gas cylinder 10 and the liquid oxygen inside the mixed gas cylinder 10 can be heated by the heating lamp 4. Heating the liquid oxygen can accelerate its heat absorption efficiency, thereby speeding up the vaporization rate of the liquid oxygen. Through the above technical solution, the mixing efficiency of the equipment for the mixed gas cylinder 10 containing liquid oxygen is improved.

[0031] When heating the mixed gas cylinder 10 with the heating lamp 4, care must be taken not to heat the mixed gas cylinder 10 to above 40 degrees Celsius in order to avoid accidents.

[0032] Both ends of the roller shaft 17 are located inside the placement frame 8, and the roller shaft 17 located inside the placement frame 8 is connected to the placement frame 8 by roller bearings; the roller bearing structure between the placement frame 8 and the roller shaft 17 can ensure the stability of the roller shaft 17 when rotating.

[0033] Below the mixing motor 5 is a circular cover plate located on the lower end face of the bottom housing 1 of the mixing device, and the bottom housing 1 of the mixing device and the circular cover plate are fixed together by screws; the circular cover plate can protect the internal structure of the bottom housing 1 of the mixing device, and when the internal structure of the bottom housing 1 of the mixing device fails, the circular cover plate can be removed to repair its internal structure.
