Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of gas-liquid mixing devices. BACKGROUND

[0002] The advantages of gas-liquid mixing operation include suitable temperature and sufficient time. Low temperature increases the viscosity of the liquid, but it is beneficial to gas-liquid mixing operation, so maintaining suitable low temperature conditions is positive for gas-liquid mixing operation. However, the production mode of improving mixing effect by a single factor often has the problem of limited production, which leads to low production of gas-liquid mixing in the prior art. SUMMARY

[0003] The technical problem to be solved by the utility model is how to improve the gas-liquid mixing effect by increasing the mixing time.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: the gas-liquid mixing device comprises a material input pipe, a gas input pipe, a mixer, a booster pump, a static holding mixing pipe, a circulating conveying pipe, valve I and valve II, the material input pipe and the circulating conveying pipe are connected with the liquid input end of the mixer, the gas input pipe is connected with the gas input end of the mixer, the output end of the mixer is connected with the input end of the booster pump through a pipeline, the output end of the booster pump is connected with the static holding mixing pipe through a pipeline, the output end of the static holding mixing pipe is connected with valve I, the circulating conveying pipe is connected with the output end of the static holding mixing pipe and located upstream of valve I, valve II is installed on the circulating conveying pipe, the static holding mixing pipe is provided with a tubular body, the body is provided with turbulence sections, the turbulence sections comprise wave crests protruding into the body and spaced around the center line of the body, and the wave crests of adjacent turbulence sections on the body are distributed in staggered positions along the center line of the body.

[0005] The design idea of the above scheme is to increase the conveying path and prolong the conveying path to increase the mixing time under the condition that the space occupied by the equipment remains unchanged. The key lies in the structural optimization of the static holding mixing pipe. Turbulence sections are provided on the body of the static holding mixing pipe. The turbulence sections comprise wave crests protruding into the body. The design of the turbulence sections is realized by pipe extrusion processing, so that the turbulence sections and the body are an integral structure. The wave crests form a concave-convex flow path inside the body. Compared with the original straight-through internal structure of the body, the concave-convex internal structure of the body changes the conveying path, so that the conveying path is curved and has a longer conveying path. The time of the material passing through the static holding mixing pipe is increased, which realizes the purpose of improving the gas-liquid mixing effect by increasing the mixing time. The wave crests change the conveying path and play a turbulence role at the same time. The staggered distribution feature of adjacent turbulence sections also promotes the generation of turbulence. Turbulence can make the materials collide with each other, which helps to improve the mixing effect.

[0006] In order to obtain the best flow path, the spoiler section is provided with two antinodes which are symmetrically distributed relative to the center line of the body, the height of the antinodes protruding into the body is greater than one fourth of the inner diameter of the body and less than one half of the inner diameter of the body.

[0007] The spoiler section is integrated with the body, which helps to keep the inside of the static holding mixing pipe smooth and seamless, avoiding flow dead angle, and in order to further ensure that there is no flow dead angle or health dead angle in the body, the cross section of the antinode is oval, and the extension direction of the antinode is parallel to the center line of the body. This structure is easy to establish a sterile environment and can also meet the delivery requirements of sterile materials.

[0008] The space defined between the antinodes guides the flow of the material while forcing the material to generate turbulence at a local position of the body part, causing the material to collide and generate more mixing effect, and in order to further strengthen the mixing effect obtained based on the turbulence, the length of the antinode in the direction along the center line of the body is less than the distance between adjacent spoiler sections.

[0009] As mentioned above, low temperature conditions help gas-liquid mixing operation, in order to avoid the liquid material containing gas absorbing heat and warming up when passing through the static holding mixing pipe, the static holding mixing pipe is provided with a heat preservation sleeve, the heat preservation sleeve is located outside the body, and the heat preservation sleeve is provided with a breathing hole. There is air between the heat preservation sleeve and the body, and air is a good thermal insulation material. By arranging a fixed air layer around the body, the purpose of preventing external heat from being transferred to the body is achieved, thereby maintaining the low temperature state of the liquid material containing gas in the body to the greatest extent.

[0010] The above technical scheme is adopted in the utility model: the gas-liquid mixing device increases the length of the flow path under the premise of not occupying more space, increases the time of the material on the conveying path, and keeps the material in a turbulent state during conveying, thereby increasing the mixing effect.
