[0002] In online water quality analysis, the performance of the mixing device directly affects the accuracy and efficiency of the test results. Currently, some mixing devices based on mechanical stirring, pneumatic mixing, and magnetic drive technologies have appeared on the market. However, these devices usually require complex transmission components or additional power support in their structural design, and they also have certain limitations in terms of mixing uniformity. In addition, some devices are prone to generating dead zones during operation, resulting in insufficient sample mixing and affecting the accuracy of the analysis.

[0003] For example, the Chinese invention patent (application number: 202110123456.7) discloses a "mixing device for water quality testing," which includes a base, a support frame fixedly connected to the base, a drive motor mounted on the top of the support frame, a stirring shaft connected to the output shaft of the drive motor via a coupling, multiple sets of stirring blades on the outer side of the stirring shaft, a fixing groove on the base, a mixing container installed in the fixing groove, and a heating component at the bottom of the mixing container. This application achieves preliminary mixing of liquids through multiple sets of stirring blades and improves mixing efficiency by using a heating component; however, the above patent still has problems with dead zones in mixing and high energy consumption in practical applications, indicating that there is still room for improvement in the existing technology in terms of mixing effect and energy consumption.

[0004] Therefore, we have made improvements to this and proposed an online water quality analysis mixing device. Utility Model Content

[0005] The purpose of this invention is to solve the problems of numerous dead zones in existing online water quality analysis mixing devices, insufficient mixing uniformity, and high energy consumption.

[0006] To achieve the above-mentioned objectives and improve the above-mentioned problems, this utility model provides an online water quality analysis mixing device, including a mixing drive structure and a mixing execution structure. The top of the mixing drive structure is provided with a fixing component, and the mixing execution structure is located inside the mixing drive structure.

Adjusting components are provided on both sides of the mixing drive structure, and guide components are provided inside the adjusting components.

[0007] The hybrid execution structure includes a rotating disk, with several guide plates fixedly arranged on the circumference of the rotating disk. A baffle is provided between each of the guide plates, and a flow-dividing hole is opened on the surface of the baffle. The hybrid drive structure includes two transmission wheels located on both sides of the rotating disk. When the transmission wheels rotate in the liquid container, they generate shear force and eddy effect on the liquid through the baffle and guide plates, thereby realizing multi-directional flow of the liquid.

[0008] As a preferred technical solution of this application, the fixing component includes a mounting plate, and the top of the mounting plate has two mounting slots that communicate with the bottom of the mounting plate, and the two transmission wheels are respectively located inside the two mounting slots.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] By designing a mixing execution structure and a mixing drive structure, the problem of dead zones in traditional mixing devices is solved. Specifically, the rotating disk in the mixing execution structure rotates at high speed driven by a transmission wheel. The guide plates on its circumferential side exert initial shear force on the liquid during rotation, while the flow-dividing holes on the baffles further divide the liquid into multiple smaller streams, creating a complex vortex effect within the container. This design not only avoids the dead zones caused by the unidirectional movement of traditional stirring blades but also significantly improves the uniformity of liquid mixing. Furthermore, the sliding rails and sliders in the mixing drive structure work together to flexibly adjust the position of the mounting plate according to the height of the liquid container, ensuring the rotating disk is always at the optimal working height, further improving mixing efficiency. These technical measures effectively reduce energy consumption during device operation, simplify the structural design, and reduce the use of complex transmission components, thereby lowering manufacturing costs.

[0018] Through the above technical solution, this utility model solves the problems of numerous dead zones in the mixing device, insufficient mixing uniformity, and high energy consumption in the prior art, and meets the demand for high-precision mixing in the process of online water quality analysis.

[0027] This utility model provides an online water quality analysis mixing device, the specific implementation of which is described in detail with reference to the accompanying drawings. Figure 1As shown, the mixing device includes a mixing drive structure 1 and a mixing execution structure 2. A fixing component 3 is provided on the top of the mixing drive structure 1, and the mixing execution structure 2 is located inside the mixing drive structure 1. The fixing component 3 includes a mounting plate 11. Two mounting slots communicating with the lower part of the mounting plate 11 are formed at the top of the mounting plate 11, and two transmission wheels 10 are respectively located inside the two mounting slots. A through hole communicating with the lower part of the mounting plate 11 is also formed at the top of the mounting plate 11, located between the two mounting slots. The mixing drive structure 1 also includes two support seats 12 fixedly connected to the bottom end of the mounting plate 11. The two transmission wheels 10 are respectively connected to opposite sides of the two support seats 12 via bearings. A rotating disk 6 is connected between the two support seats 12 via a bushing. A limiting seat fixedly connected to the mounting plate 11 is provided on the opposite side of the two transmission wheels 10.

[0028] The hybrid execution structure 2 includes a rotating disk 6, with several guide plates 7 fixedly mounted on its circumference. Baffles 8 are positioned between the guide plates 7, and flow-diverting holes 9 are formed on the surface of each baffle 8. A rack is fixedly mounted on the circumference of the drive wheel 10. When the drive wheel 10 rotates within the liquid container, it generates shear force and eddy currents in the liquid through the baffles 8 and guide plates 7, thereby achieving multi-directional flow of the liquid. Adjusting components 4 are provided on both sides of the hybrid drive structure 1, with guide components 5 inside each adjusting component 4. Each adjusting component 4 includes a slide rail 13, which is used to connect with the guide component 5. The guide component 5 includes a slider 14 slidably disposed inside the slide rail 13, and the slider 14 is fixedly connected to the mounting plate 11. An elastic element 15 is fixedly mounted inside the slide rail 13, and the end of the elastic element 15 is fixedly connected to the slider 14.

[0029] Combination Figures 2 to 4 The specific implementation process of this utility model is further described below. The mounting plate 11 serves as the fixed foundation for the entire device, and its top mounting groove accommodates the transmission wheel 10 and provides it with rotation space. The transmission wheel 10 is connected to the support seat 12 via bearings, ensuring that the transmission wheel 10 can rotate smoothly without deviation. The rotating disk 6 is connected between the two support seats 12 via bushings, forming a stable center of rotation. Multiple guide plates 7 are evenly distributed on the circumference of the rotating disk 6. The number and size of the guide plates 7 are designed according to actual needs to ensure that the liquid is subjected to sufficient shear force during rotation. Baffles 8 are disposed between adjacent guide plates 7. The surface of the baffles 8 has diversion holes 9. The shape of the diversion holes 9 can be circular, elliptical, or other regular or irregular shapes. Their main function is to divide the liquid, allowing it to form a more complex fluid path during flow.

[0030] A rack is fixedly mounted on the circumferential side of the drive wheel 10. The rack design allows the drive wheel 10 to be driven to rotate by an external drive device, such as a motor. When the drive wheel 10 rotates, its rack meshes with the corresponding structure on the rotating disk 6, thereby transmitting the rotational motion to the rotating disk 6. During the high-speed rotation of the rotating disk 6, the guide plate 7 first applies shear force to the liquid, causing the liquid to flow along the surface of the guide plate 7. Due to the presence of the baffle 8, the liquid is divided into multiple small streams by the diversion holes 9 when passing through the baffle 8, and each stream forms a local vortex under the action of the baffle 8. This local vortex, together with the shear force generated by the guide plate 7, causes the liquid to form a complex multidirectional flow in the container, thereby avoiding the dead zones present in traditional stirring devices.

[0031] The adjusting element 4 and guide element 5 are designed to accommodate liquid containers of different heights. The adjusting element 4 includes a slide rail 13, inside which is a slider 14, which is fixedly connected to the mounting plate 11. An elastic element 15 is fixedly installed inside the slide rail 13, and its end is fixedly connected to the slider 14. When the height of the mounting plate 11 needs to be adjusted, the slider 14 slides along the slide rail 13, and the elastic element 15 provides a certain elastic force to maintain the stability of the slider 14. By adjusting the position of the slider 14, the mounting plate 11, its drive wheel 10, and the rotating disk 6 can be adjusted to the optimal working height, thereby ensuring that the rotating disk 6 is always in the appropriate position inside the liquid container.

[0032] In practical applications, the mixing device of this invention is suitable for various online water quality analysis scenarios. For example, in water quality monitoring laboratories, liquid samples usually need to be thoroughly mixed before accurate analysis. When using the mixing device of this invention, the liquid sample is first poured into a liquid container, and then the external drive device is activated to rotate the transmission wheel 10. The transmission wheel 10 transmits power to the rotating disk 6 through a rack and pinion, and the rotating disk 6 drives the guide plate 7 and the baffle plate 8 to shear and divide the liquid. Under the combined action of the guide plate 7 and the baffle plate 8, the liquid forms a complex vortex effect, and the components in the liquid are rapidly and uniformly distributed. Throughout the mixing process, the cooperation of the slide rail 13 and the slider 14 ensures that the rotating disk 6 is always at the optimal working height, thereby improving mixing efficiency and reducing energy consumption.

[0033] Furthermore, the structure of this invention is simple and easy to maintain. Since the power transmission between the transmission wheel 10 and the rotating disk 6 is mainly accomplished by rack and pinion, the use of complex transmission components is reduced, thereby lowering manufacturing costs and maintenance difficulty. At the same time, the design of the elastic element 15 gives the slider 14 a certain degree of self-adaptability within the slide rail 13, enabling it to accommodate liquid containers of different sizes, further enhancing the versatility of the device.

[0034] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principles of this utility model are further explained below in conjunction with specific application scenarios.

[0035] In online water quality analysis laboratories, liquid samples typically require thorough mixing before accurate testing. When using the mixing device of this invention, the liquid sample to be mixed is first poured into a liquid container, ensuring the container is securely placed on the work platform. Then, an external drive device (such as a motor) is activated, driving the transmission wheel 10 to rotate. A rack is fixedly mounted on the circumference of the transmission wheel 10, meshing with a corresponding structure on the rotating disk 6, thereby transmitting the rotational motion to the rotating disk 6. This power transmission process ensures that the rotating disk 6 can rotate at a set speed.

[0036] When the rotating disk 6 begins to rotate, the guide plates 7, evenly distributed along its circumference, first apply shear force to the liquid. This shear force causes the liquid to flow along the surface of the guide plates 7, forming an initial radial flow tendency. Since the baffles 8 are positioned between adjacent guide plates 7, and their surfaces have diversion holes 9, the liquid is divided into multiple small streams as it passes through them. These small streams further form local eddies under the action of the baffles 8. The combined effect of these local eddies and the shear force generated by the guide plates 7 creates a complex multi-directional flow path within the container. This flow pattern not only avoids the dead zones caused by unidirectional movement in traditional stirring devices but also significantly improves the mixing uniformity of the liquid.

[0037] During the mixing process, the design of the adjusting component 4 and the guide component 5 plays a crucial role. The adjusting component 4 includes a slide rail 13, inside which is a slider 14, which is fixedly connected to the mounting plate 11. An elastic element 15 is fixedly installed inside the slide rail 13, with its end fixedly connected to the slider 14. When the height of the mounting plate 11 needs to be adjusted, the slider 14 slides along the slide rail 13, and the elastic element 15 provides a certain elastic force to maintain the stability of the slider 14. By adjusting the position of the slider 14, the mounting plate 11, its drive wheel 10, and the rotating disk 6 can be adjusted to the optimal working height, thereby ensuring that the rotating disk 6 is always in the appropriate position within the liquid container. This height-adjustable design allows this invention to adapt to liquid containers of different sizes, enhancing the versatility of the device.

[0038] Furthermore, the structure of this invention is simple and easy to maintain. Power transmission between the transmission wheel 10 and the rotating disk 6 is mainly accomplished by a rack and pinion, reducing the use of complex transmission components and thus lowering manufacturing costs and maintenance difficulty. Simultaneously, the design of the elastic element 15 allows the slider 14 to have a certain degree of self-adaptability within the slide rail 13, enabling it to automatically adjust its position when dealing with liquid containers of different sizes, further improving the stability and reliability of the device.

[0039] Throughout the mixing process, the liquid sample forms a complex vortex effect under the combined action of the guide plate 7 and the turbulence deflector 8, allowing the components in the liquid to be rapidly and uniformly distributed. Through these technical means, this invention effectively solves the problem of dead zones in traditional mixing devices, while significantly improving mixing efficiency and reducing energy consumption. This design meets the high-precision mixing requirements of online water quality analysis, providing a strong guarantee for the accuracy and reliability of experimental results.

Electrical control components not mentioned in this technical solution are prior art and are therefore not shown in the figures, nor will they be described further here.
