DETAILED DESCRIPTION

[0023] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] In the description of the present invention, it should be understood that the orientations or positional relationships indicated by the terms "top", "bottom", "inside", "outside", "circumferential", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] like Figures 1 to 6As shown, a gas-liquid mixing device of the present invention includes a mixing container 1, a gas delivery component 2 and an infusion component 3. The mixing container 1 is provided with a mixing chamber 11, the gas delivery component 2 includes a first gas delivery pipe 31, the first gas delivery pipe 31 is connected to the mixing chamber 11, and gas can be input into the mixing chamber 11 through the first gas delivery pipe 31. The infusion component 3 is provided with a plurality of liquid delivery ports 21, and each of the liquid delivery ports 21 is arranged correspondingly so that the liquid sprayed from the liquid delivery ports 21 collides in the mixing chamber 11.

[0027] In the above technical scheme, the first gas delivery pipe 31 of the gas delivery component 2 is connected to the mixing chamber 11, and gas can be input into the mixing chamber 11 through the first gas delivery pipe 31 to fill the mixing chamber 11 with gas. The infusion component 3 is provided with a plurality of corresponding liquid delivery ports 21. When each liquid delivery port 21 sprays liquid, the liquids can collide in the mixing chamber 11, and the gas is dissolved in the liquid delivered to the mixing chamber 11. Among them, since the liquid will be dispersed into many smaller liquid particles after the collision, the contact area between the liquid and the gas is greatly improved, so that the gas can be quickly dissolved in the liquid. In summary, the gas-liquid mixing device of the present invention can disperse the liquid through the collision of the liquid, greatly increase the contact area between the liquid and the gas, so that the gas can be quickly dissolved in the liquid. In a mixing process, the solubility of the gas in the liquid is relatively high, which can meet the requirements of industrial production.

[0028] Furthermore, the infusion assembly 3 may also include a water pump, and the liquid may be delivered to the liquid delivery port 21 by the water pump, or the liquid may be delivered to the liquid delivery port 21 by utilizing potential energy.

[0029] Furthermore, the infusion assembly 3 includes multiple first infusion tubes 23, and the liquid delivery port 21 is arranged at one end of the first infusion tube 23, wherein the first infusion tube 23 can pass through the mixing container 1, with one end located outside the mixing container 1 and the other end located in the mixing chamber 11, and the first infusion tube 23 can also be entirely located in the mixing chamber 11.

[0030] Furthermore, the infusion assembly 3 includes two first infusion tubes 23, and the liquid delivery ports 21 of the two first infusion tubes 23 are opposite to each other and have a gap, so that the liquid delivery ports 21 on the two first infusion tubes 23 spray in opposite directions and collide with each other, and then the liquid splashes out along the gap between the two liquid delivery ports 21.

[0031] Furthermore, the axes of the two first infusion tubes 23 are collinear, and a plurality of connecting rods 27 are provided between the ends of the two first infusion tubes 23 provided with the liquid delivery ports 21. The two ends of the connecting rod 27 are respectively connected to the two first infusion tubes 23. The plurality of connecting rods 27 are spaced apart around the axes of the first infusion tubes 23 so that the liquid delivery ports 21 of the two first infusion tubes 23 can remain relative to each other, which is convenient for installation and prevents the two first infusion tubes 23 from deviating after long-term use. Furthermore, the structure can be formed by cutting the middle part of a straight tube, and the characteristics of the first infusion tubes 23 on both sides and the middle connecting rod 27 are formed after cutting. Preferably, the two first infusion tubes 23 are arranged relative to each other in the vertical direction, so that the mixing container 1 can be manufactured as a vertical long structure to reduce the area occupied by the device. Furthermore, the connecting rod 27 can be provided with a cutting blade on the side facing the axis to further cut off the splashing liquid.

[0032] Furthermore, it also includes a cutting component 4, which includes two cutting units 41, and the cutting units 41 correspond to the first infusion tube 23 one by one. The cutting unit 41 includes a knife disc 411 and a plurality of blades 412. The knife disc 411 is sleeved on the outside of the first infusion tube 23, and the plurality of blades 412 are arranged on an end surface of the knife disc 411 and are arranged around the axis of the knife disc 411. The blades 412 protrude from the liquid delivery port 21, and the blades of the blades 412 are all facing the gap between the two liquid delivery ports 21; wherein, when the liquid splashes around, the liquid will be cut and dispersed by the blades of the blades 412 to disperse the liquid into smaller liquid particles, further increasing the contact area between the liquid and the gas.

[0033] Furthermore, the cutter disc 411 is rotatably connected to the first infusion tube 23, and the blade of the blade 412 of the cutting unit 41 is biased toward one side of the axis of the cutter disc 411, so that when the liquid splashes outward in the gap between the two liquid delivery ports, part of the liquid splashes to the side of the blade, generating thrust on the side of the blade 412, causing the cutter disc 411 to rotate, and the blade can cut more liquid at a certain speed to increase the efficiency of cutting liquid particles, thereby increasing the cutting effect.

[0034] Furthermore, the blade of the blade 412 of one cutting unit 41 is biased toward one side of the axis of the cutter disc 411, and the blade of the blade 412 of the other cutting unit 41 is biased toward the other side of the axis of the cutter disc 411, so that when the liquid splashes outward in the gap between the two liquid delivery ports 21, the cutter discs 411 of the two cutting units 41 rotate in different directions. Further, when liquid splashes onto the side of the blade 412 of one of the cutting units 41, the liquid pushes the cutter disc 411 of the cutting unit 41 to rotate (which can be in a clockwise direction), and then the liquid is splashed by the side of the blade 412 of the cutting unit 41 to the side of the blade 412 of the other cutting unit 41, and then pushes the cutter disc of the cutting unit 41 to rotate (which can be in a counterclockwise direction), so that the two cutting units 41 can accelerate each other's rotation speed.

[0035] Furthermore, the infusion assembly 3 also includes a second infusion tube 24, which is connected to one end of each of the first infusion tubes 23 away from the liquid delivery port 21. Specifically, the first infusion tube 23 is located in the mixing chamber 11, and the outer surface of the mixing container 1 is provided with a through-tube hole that penetrates the mixing chamber 11. The second infusion tube 24 passes through the through-tube hole, and one end of the second infusion tube 24 is located in the mixing chamber 11, and the end is connected to one end of the first infusion tube 23. The water pump 22 can be provided in the second infusion tube 24, and the water pump 22 is located outside the mixing container 1.

[0036] Furthermore, in order to increase the water outlet pressure of the liquid delivery port 21, the infusion component 3 also includes a water hammer generator 25, and the water hammer generator 25 is arranged in the second infusion pipe 24, wherein the water hammer generator 25 uses the inertia of the liquid flow in the pipeline to generate pulsed intermittent high pressure to increase the outlet water pressure of the liquid delivery port 21. Further, since the water hammer generator 25 intermittently increases the water pressure, in order to enable each of the liquid delivery ports 21 to simultaneously spray the same flow of liquid at the same pressure to have the best breaking up effect on the liquid, the specifications of each of the first infusion pipes 23 and the specifications of the components arranged thereon are the same. Further, the water hammer generator 25 can be located between one end of the second infusion pipe 24 connected to the first infusion pipe 23 and the water pump 22.

[0037] Furthermore, the first liquid infusion pipe 23 is provided with a Venturi section 26 to further increase the liquid flow rate and liquid pressure; the gas delivery component 2 also includes a plurality of second gas delivery pipes 32 corresponding one-to-one to the first liquid infusion pipe 23, one end of the second gas delivery pipe 32 is connected to the side wall of the Venturi section 26, and the second gas delivery pipe 32 is used to deliver gas to the Venturi section 26 for mixing so that part of the gas is dissolved in the liquid in the Venturi section 26. Specifically, the outer surface of the mixing container 1 is provided with a plurality of gas delivery holes that penetrate into the mixing chamber 11, and the gas delivery holes correspond one-to-one to the second gas delivery pipes 32, and the second gas delivery pipe 32 passes through the gas delivery holes.

[0038] Furthermore, it also includes a liquid outlet pipe 5, which is connected to the mixing container 1, and its tube hole is connected to the mixing chamber 11. Specifically, the bottom surface of the mixing container 1 is provided with a liquid outlet hole that penetrates into the mixing chamber 11, and the liquid outlet pipe 5 is connected to the liquid outlet hole. The upper end of the liquid outlet pipe 5 is not higher than the bottom of the mixing chamber 11, so that the liquid in the mixing chamber 11 can be smoothly discharged along the mixing chamber 11.

[0039] Furthermore, the gas-liquid mixing device of the present invention can be operated without using a driver or only using a small number of drivers. Therefore, the gas-liquid mixing device of the present invention is more energy-efficient than a general gas-liquid mixing device.

[0040] Furthermore, the specific connection methods of fixed setting and fixed connection refer to the relative position relationship of two components that can be fixedly connected, including fixing by connecting parts, fixing by welding, fixing by adhesives, fixing by integral molding, and fixing by snap connections.

[0041] Furthermore, the connecting parts include fasteners, straps, ties, pneumatic connecting elements, hydraulic connecting elements, flange plates, Velcro, and buttons.

[0042] In summary, the embodiment of the present invention provides a gas-liquid mixing device, and its technical effects are:
