Description

Technical Field

[0001] This utility model relates to the field of valves, specifically a vortex liquid mixing valve. Background Technology

[0002] Traditional liquid mixing valves generally face significant technical challenges in achieving efficient and controllable mixing.

[0003] Many existing liquid mixing valves have a relatively simple design concept, often employing a confluence mixing approach. This means they simply guide two or more fluids to a single point, relying on the fluids' natural diffusion to complete the mixing process. However, this passive mixing method is inefficient, especially when dealing with fluids with large differences in viscosity, density, or flow rate. Due to the lack of active shear forces or eddy currents, fluid components struggle to disperse and penetrate sufficiently and uniformly within a short time. As a result, the mixed fluid often exhibits localized concentration inhomogeneities, and may even show significant stratification, which is unacceptable for many industrial applications with stringent requirements for mixing uniformity. For example, in chemical production, uneven mixing can lead to inefficient reactions; in food processing, it can affect the taste and stability of the product.

[0004] Other traditional mixing valves may incorporate fixed-structure flow guides, such as helical blades or curved channels commonly found in static mixers. These flow guides can indeed promote mixing to some extent by altering the fluid path and generating turbulence. However, the fundamental drawback of this type of design is that its mixing state is preset and immutable. Once the valve is manufactured, the geometry and arrangement of its internal flow guide structure are fixed, meaning that the mixing intensity and pattern it provides are also constant. This unadjustability prevents the valve from flexibly adapting to changes in external conditions. For example, when the fluid flow rate changes, or the properties of the fluid to be mixed change (such as viscosity or temperature), or even when the requirements for mixing uniformity in the final product are adjusted, these valves are difficult to adapt through their own structure. Users cannot dynamically adjust the mixing process according to actual needs, which greatly limits the versatility and efficiency of the valves under varying operating conditions, and also makes them unsuitable for applications requiring precise control of the mixing process. Utility Model Content

[0005] The main purpose of this utility model is to provide a vortex liquid mixing valve, which aims to solve the technical problems of low mixing efficiency, poor uniformity, and inability to adaptively adjust the mixing intensity according to the working conditions of existing mixing valves.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vortex liquid mixing valve includes a valve body, wherein an inlet section, a mixing section and an outlet section are sequentially arranged in the valve body and are interconnected.

[0008] Within the mixing section, a first guide block and a second guide block are rotatably disposed, and both the first guide block and the second guide block have flow holes.

[0009] The key feature is that a drive assembly is also installed inside the valve body. The core function of this drive assembly is to use the energy of the fluid itself to drive the first guide block and the second guide block to rotate in opposite directions.

[0010] Specifically, the drive assembly includes a propeller rotatably disposed within the water inlet section. The propeller is fixedly connected to a drive shaft that passes through and is fixedly connected to the first guide block, thereby directly transmitting the rotation of the propeller to the first guide block.

[0011] The other end of the drive shaft is connected to a first driving bevel gear. To achieve reverse rotation, the drive assembly also includes at least one rotatable intermediate gear, and a second driving bevel gear is fixedly connected to the second guide block. The transmission relationship is as follows: the first driving bevel gear, the intermediate gear, and the second driving bevel gear mesh sequentially. Through this ingenious arrangement of the gear system, the reverse rotation of the second guide block relative to the first guide block is achieved.

[0012] Furthermore, the axis of the flow passage intersects the axis of the valve body at an angle of 30-75 degrees.

[0013] Furthermore, the first guide block has three flow holes, and the second guide block has four flow holes.

[0014] Furthermore, the number of intermediate gears is two.

[0015] Furthermore, the drive assembly includes a housing, which is fixed within the mixing section by fixing ribs.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. High mixing efficiency and good uniformity: By setting up rotating first and second guide blocks, the fluid is forced to undergo intense shearing, tearing, and rotation as it flows through them. The strong vortex effect generated by this counter-rotation far exceeds that of traditional static mixers or simple confluence structures, enabling thorough mixing of the fluid at the microscale in a very short distance and time, effectively solving the problems of stratification and localized uneven concentration.

[0018] 2. Adaptive Adjustment of Mixing Intensity: The driving force of this invention originates from the kinetic energy generated by the fluid flowing over the helical drive propeller. Therefore, when the inlet flow velocity increases, the rotational speed of the helical drive propeller increases accordingly, thereby increasing the rotational speed of the two guide blocks and enhancing the mixing intensity; conversely, when the flow velocity decreases, the mixing intensity also weakens accordingly. This design allows the mixing intensity to dynamically match the flow rate, achieving adaptive adjustment without the need for external power or control systems, thus broadening the valve's applicability to different operating conditions.

[0019] 3. Compact structure and high energy efficiency: This invention integrates driving, transmission, and mixing functions into a compact valve body, directly utilizing fluid energy to drive the mixing process without external energy consumption, thus meeting energy-saving requirements. The overall structural design is reasonable, achieving efficient energy conversion and utilization. Attached Figure Description

[0028] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0029] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1-2 As shown, this vortex liquid mixing valve includes a valve body 1. A fluid channel is formed inside the valve body 1, which is sequentially divided into an inlet section 111, a mixing section 112, and an outlet section 113. Two or more liquids to be mixed enter the valve body 1 from the inlet section 111.

[0031] Within the mixing section 112 of the valve body 1, two key rotating components are installed: a first guide block 120 and a second guide block 130. Both guide blocks can rotate freely within the valve body 1 around its central axis. To allow fluid to pass through, both the first guide block 120 and the second guide block 130 are provided with multiple flow holes 150.

[0032] The drive assembly 140 includes a propeller 141 disposed in the water inlet section 111. When fluid enters the valve body 1, it impacts the blades of the propeller 141, causing it to rotate like a windmill.

[0033] The left end of the drive shaft 142 is fixedly connected to the propeller 141, so the drive shaft 142 will rotate synchronously. The drive shaft 142 extends rearward from the water inlet section 111, passes through the center of the first guide block 120 and is fixedly connected to it. In this way, the rotational motion of the propeller 141 is directly transmitted to the first guide block 120, causing it to rotate.

[0034] The drive shaft 142 continues to extend rearward, and a first drive bevel gear 143 is fixedly connected to its end. Within the mixing section 112, one or more intermediate gears 144 and a second drive bevel gear 145 are also provided. The second drive bevel gear 145 is fixed to the second guide block 130.

[0035] The transmission path is as follows: the rotation of the first driving bevel gear 143 drives the intermediate gear 144 meshing with it to rotate; the intermediate gear 144 then drives the second driving bevel gear 145 meshing with it to rotate. Through this gear system configuration, it can be ensured that when the first driving bevel gear 143 (and the first guide block 120) rotates clockwise, the second driving bevel gear 145 (and the second guide block 130) will rotate counterclockwise, thereby achieving stable counterclockwise rotation of the two guide blocks.

[0036] To ensure the stability and service life of the gear transmission mechanism, components such as the first drive bevel gear 143, the intermediate gear 144, and the second drive bevel gear 145 can be housed within a separate drive assembly 140 housing. This housing is securely mounted on the inner wall of the mixing section 112 by several fixing ribs 146, which not only protects the gear train from direct fluid erosion but also provides reliable support for the entire rotating system.

[0037] Work process

[0038] When the liquid to be mixed flows into the valve body 1 from the inlet section 111, it first impacts the propeller 141, causing it to rotate. The propeller 141 drives the first guide block 120 to rotate via the drive shaft 142, and simultaneously drives the second guide block 130 to rotate in the opposite direction via the first drive bevel gear 143, the intermediate gear 144, and the second drive bevel gear 145. The fluid then enters the first and second guide blocks 120 and 130, which are rotating in the opposite direction, and is forced to pass through their flow holes 150. Due to the high-speed opposing rotation of the two guide blocks, the fluid is subjected to strong shear and centrifugal forces as it passes through, forming complex, opposing vortices. This intense turbulent state allows the fluid molecules of different components to disperse and penetrate rapidly and fully, so that a highly homogeneous mixed liquid has been formed when it flows out of the mixing section 112, and is finally discharged from the outlet section 113.

[0039] Preferred solution

[0040] As a preferred option, the axis of the flow passage 150 can be designed to form a specific angle with the central axis of the valve body 1, such as an angle of 30 to 75 degrees. This inclined channel design, combined with the rotation of the guide block itself, can guide the fluid to generate a spiral forward three-dimensional motion trajectory, further enhancing the radial and axial mixing effect and ensuring that there are no dead zones in the mixing.

[0041] As another preferred option, the number of flow holes 150 on the first guide block 120 can be different from the number of flow holes 150 on the second guide block 130. For example, the first guide block 120 has 3 flow holes 150, while the second guide block 130 has 4 flow holes 150. This asymmetrical design can avoid the periodic complete alignment of the two sets of holes during rotation, thereby preventing continuously changing and irregular flow disturbances, further breaking the laminar flow of the fluid, and improving the degree of chaos and uniformity of the mixing.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
