[0002] In some work, it is often necessary to prepare a standard solution of a specific gas dissolved in a liquid. The volume of the gas must be precisely quantified and all of it must be dissolved in the liquid to form a uniform, stable single liquid standard solution. The mixing of gas and liquid is quite different from the mixing of liquids.

[0003] Currently, conventional gas-liquid mixing is mostly static mixing, which is achieved through the flow of liquid. However, the amount of dissolved gas is small, resulting in poor gas-liquid mixing ability and easily causing liquid stratification, affecting the uniformity of mixing.

[0004] Therefore, in order to solve the above problems, we propose a jet-type gas-liquid rotating mixing device to achieve synchronous dynamic mixing of gas and liquid, and the gas is directly sprayed into the liquid, which makes the mixing effect better. Utility Model Content

A fixing seat 54 is fixedly installed at the end of the connecting rod 53 away from the connecting seat 52. An injection pipe 55 is fixedly installed on the fixing seat 54 (wherein the connecting seat 52 and the connecting rod 53 and the connecting seat 52 are all provided with gas channels, so that the gas enters the gas channel through the hollow cavity of the hollow rotating shaft 51 and finally enters the injection pipe 55). The surface of the injection pipe 55 is provided with a plurality of injection holes at equal intervals. The liquid and gas are delivered through the liquid delivery pipe and the gas delivery pipe, and the liquid delivery pipe and the gas delivery pipe are connected to the liquid storage and gas storage equipment. When delivering the materials, the liquid can be directly delivered by conventional means of pumping, while the gas delivery pipe needs to be connected to a pressure pump to pressurize and deliver the gas, so that the gas enters the injection pipe 55 after passing through the hollow rotating shaft 51, and is sprayed by the injection holes on the surface, and the adaptive driving component drives the injection pipe 55 to rotate in the mixing tank 1, thereby realizing dynamic spraying and improving the mixing effect.

[0026] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5 In this embodiment, the driving assembly includes an outer cover body 41 fixedly connected to the upper end of the top cover 4, a driving motor 42 is fixedly installed on the upper end of the outer cover body 41, and the output end of the driving motor 42 extends to the inner side of the outer cover body 41 and is fixedly installed with a transmission wheel 43.

The two transmission wheels 43 are connected by a transmission belt. When the transmission wheel 43 rotates, the power of the drive motor 42 is transmitted to the outer cover 41 through the transmission of the belt. The injection pipe 55 is inclined, and the inclination of the injection pipe 55 is adapted to the inner wall of the mixing tank 1. There are two injection pipes 55.

[0028] See also Figure 3 and Figure 4 The gear 31 is rotated in the opposite direction to the gear 31, and the lower movement of the lifting frame 32 causes the gear 31 to rotate in the opposite direction, which can drive the mixing tank 1 to swing, thereby cooperating with the mixing and preventing the liquid from stratifying and settling.

[0029] During operation, the liquid is first sent into the mixing tank 1 through the infusion tube. During mixing, gas is supplied through the gas pipe. The gas enters the injection pipe 55 through the hollow shaft 51 and drives the motor 42 to drive the rotation of the transmission wheel 43. It can be synchronously transmitted to the hollow shaft 51 to drive the injection pipe 55 to rotate, realize dynamic gas transportation, and adapt to the rotating stirring assembly on the top. The servo motor 61 drives the rotating rod 6 to rotate. The rotation of the stirring rod realizes the stirring and mixing of the liquid, ensuring the mixing effect. At the same time, the lifting cylinder 7 is used to push the lifting frame 32 to move up and down, and the power is converted into rotational motion through the gear 31 during movement, which can drive the mixing tank 1 to swing, prevent the liquid from stratifying and settling, and improve the mixing effect.

[0030] Through the above steps, the gas enters the injection pipe 55 after passing through the hollow rotating shaft 51, and the injection is formed by the injection hole on the surface. The adaptive driving component drives the injection pipe 55 to rotate in the mixing tank 1 to achieve dynamic injection, thereby improving the mixing effect, so as to solve the problem that the existing gas-liquid rotating mixing equipment has a small amount of dissolved gas, resulting in poor gas-liquid mixing ability.
