Description

Technical Field

[0001] This invention relates to the field of agitator technology, and more particularly to a high-efficiency combined agitator for automotive brake fluid. Background Technology

[0002] Currently, high-efficiency combined mixing tanks are commonly used in the production of automotive brake fluid for mixing and homogenization. These mixing tanks typically consist of a tank body, a drive motor, a mixing shaft, and multiple layers of blades. Basic mixing can be achieved by controlling the mixing speed and time. Some advanced equipment also integrates heating and vacuum degassing functions to adapt to the physicochemical properties of components such as alcohols, ethers, and corrosion inhibitors in the brake fluid formulation, thereby improving production efficiency and product stability.

[0003] However, existing high-efficiency combined stirred tanks still have significant limitations in practical applications. In particular, the single stirring method makes it difficult to meet the mixing requirements of high-performance brake fluid production. Currently, most stirred tanks rely on fixed-angle blades for unidirectional rotational stirring. Although this can form an overall circulation, it is difficult to generate complex, multidirectional fluid movement within the tank. Especially for components with large viscosity differences or poor miscibility, it is easy to cause local mixing dead zones and uneven component distribution. Brake fluid is usually composed of multiple additives such as polyol ethers, lubricants, and rust inhibitors. The density, viscosity, and compatibility of each component are different. A single stirring mode can easily lead to the floating of light components, the sedimentation of heavy components, or insufficient dispersion of additives. This not only affects the uniformity of the product but may also cause corrosion inhibitor failure or high-temperature vapor lock risks due to excessively high local concentrations. In addition, the unidirectional shear force is weak, making it difficult to effectively break up clumps or agglomerates, which reduces the long-term stability and resistance to damp heat of the brake fluid. Although existing technologies can improve the mixing degree by extending the stirring time or increasing the rotation speed, this will exacerbate the increase in energy consumption and the risk of material thermal degradation.

[0004] Therefore, how to provide a high-efficiency combined mixing tank for automotive brake fluid is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One object of the present invention is to provide a high-efficiency combined stirring vessel for automotive brake fluid, which solves the problems mentioned in the background art.

[0006] According to an embodiment of the present invention, a high-efficiency combined mixing tank for automotive brake fluid includes a mixing tank body. A mounting bracket for placing on the ground is fixedly sleeved on the surface of the mixing tank body. A main shaft assembly is rotatably connected to the top of the mixing tank body. The bottom end of the main shaft assembly extends into the interior of the mixing tank body. A drive assembly for driving the main shaft assembly to rotate is fixedly installed at the top of the mixing tank body corresponding to the main shaft assembly. A positioning assembly is fixedly installed at the top of the mixing tank body. A driven assembly is movably installed inside the main shaft assembly. The top end of the driven assembly extends to the positioning assembly and is movably connected to the positioning assembly. A rotating assembly is rotatably installed on the surface of the main shaft assembly located inside the mixing tank body. The rotating assembly and the driven assembly mesh with each other. A mixing blade is fixedly installed on the side section of the rotating assembly.

[0007] The main shaft assembly includes a central shaft and a shaft-shaped housing. The shaft-shaped housing is fixedly sleeved on the surface of the central shaft and is rotatably mounted on the top of the mixing tank via a sealed bearing.

[0008] The drive assembly includes a drive motor, a drive gear, and a transmission gear. The drive motor is fixedly installed on the top of the mixing tank, the drive gear is fixedly installed on the output shaft end of the drive motor, and the transmission gear is fixedly installed on the top of the shaft-shaped housing. The drive gear and the transmission gear mesh with each other.

[0009] The positioning assembly includes a mounting bracket, an adjusting component, a positioning block, and an annular wave groove. The mounting bracket is fixedly installed on the top of the mixing tank, the adjusting component is located on the top of the mounting bracket, the bottom end of the adjusting component is fixedly connected to the top of the positioning block, and the annular wave groove is formed on the surface of the positioning block.

[0010] The adjustment assembly includes an adjustment knob, a fixing screw, a positioning cylinder, and a movable block. The adjustment knob is rotatably mounted on the top of the mounting frame. The positioning cylinder is fixedly mounted on the top of the inner wall of the mounting frame. The movable block is fixedly mounted on the top of the positioning block. The positioning cylinder is movably sleeved on the top of the movable block. The fixing screw is fixedly mounted on the top of the movable block. The fixing screw passes through the adjustment knob and extends above the adjustment knob. The adjustment knob is threaded onto the surface of the fixing screw.

[0011] The driven assembly includes a driven rod, a driven tooth groove, a limiting seat, a driving ring, a driving rod, and a driving head. The limiting seat is fixedly installed on the surface of the central shaft between the shaft housing and the central shaft. The driven rod is in contact with the surface of the central shaft, and the limiting seat is movably sleeved on the surface of the driven rod. The driven rod is parallel to the central shaft. The driven tooth groove is opened on the side of the driven rod. The driving ring is movably sleeved on the surface of the central shaft and located inside the shaft housing. The top end of the driven rod is fixedly connected to the lower surface of the driving ring, and the bottom end of the driving rod is fixedly connected to the top end of the driving ring. The top end of the driving rod passes through the shaft housing and the transmission gear and extends above the transmission gear. The driving head is fixedly installed on the inner side of the driving rod near the top end, and the driving head is movably inserted into the interior of the annular wave groove.

[0012] The number of driven rods is five, and the number of rotating components and stirring blades is also five. The positions of the driven rods correspond to the positions of the rotating components and stirring blades. The five sets of driven rods, rotating components and stirring blades are arranged in a ring array with the central axis as the array center. The number of driving rods is two, and the two sets of driving rods are arranged axially symmetrically. Both sets of driving heads are movably inserted into the inside of the annular wave groove.

[0013] The rotating assembly includes a rotating shaft and a rotating gear. The rotating shaft is rotatably mounted on the surface of the central shaft pair. One end of the rotating shaft passes through the shaft-shaped housing and extends to the outside of the shaft-shaped housing. The end of the rotating shaft located outside the shaft-shaped housing is fixedly connected to one end of the stirring blade. The rotating gear is fixedly sleeved on the rotating shaft on the surface located between the shaft-shaped housing and the central shaft. The rotating gear meshes with the driven tooth groove.

[0014] The beneficial effects of this invention are: Multidimensional composite stirring is achieved, significantly improving mixing uniformity and efficiency. Through the combination of the main shaft driving the stirring blades to revolve and the driven component driving the stirring blades to rotate, a complex and multidirectional fluid shearing and convection is formed in the mixing tank. This dynamically changing stirring method can effectively break through local mixing dead zones and prevent stratification or uneven dispersion caused by differences in component density and viscosity. It is particularly suitable for materials such as brake fluid that are compounded with multiple additives, ensuring the high uniformity and stability of product composition.

[0015] While ensuring efficient mixing, this invention avoids high energy consumption and the risk of material thermal degradation. Through a mechanical linkage structure, the single rotational power source is transformed into the compound motion of the stirring blades. The enhanced mixing effect can be achieved without the need for additional drive or a significant increase in rotation speed. This reduces the dependence on long-term high-intensity mixing, thereby reducing overall energy consumption and avoiding the risk of thermal degradation of brake fluid components that may be caused by excessive shearing heat or long-term mixing, thus ensuring product performance.

[0016] The stirring mode is flexible and adjustable to adapt to different formulations and process stages. By designing independent adjustment components, the axial position of the positioning block and the annular wave groove can be easily changed, thereby macroscopically adjusting the initial tilt angle of all stirring blades. Combined with the periodic angle changes of the stirring blades themselves during operation, the flow field morphology and shear intensity of the stirring can be flexibly optimized according to different brake fluid formulations or mixing processes, enhancing the process adaptability and versatility of the equipment.

[0017] With a compact structure, reliable linkage, and stable operation, the entire angle adjustment mechanism is integrated inside the main shaft assembly. The precise guidance and transmission of motion are achieved through components such as limit seats and drive rings. The angle changes of all stirring blades are synchronously controlled by the same set of annular wave grooves, ensuring the consistency and coordination of the actions. This design achieves a significant improvement in functionality without significantly increasing the complexity of external mechanisms. The compact structure makes it easy to integrate and modify existing mixing tanks, and the mechanical linkage method is highly reliable and easy to maintain. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0028] refer to Figure 1-8 In this embodiment, a mixing tank 1 is included. A placement rack 2, which is placed on the ground, is fixedly sleeved on the surface of the mixing tank 1. A main shaft assembly 3 is rotatably connected to the top of the mixing tank 1. The bottom end of the main shaft assembly 3 extends into the interior of the mixing tank 1. The main shaft assembly 3 includes a central shaft 28 and a shaft-shaped outer shell 29. The shaft-shaped outer shell 29 is fixedly sleeved on the surface of the central shaft 28. The shaft-shaped outer shell 29 is rotatably mounted on the top of the mixing tank 1 through a sealed bearing.

[0029] In practice, the entire mixing device provides a support frame and a core rotating shaft 26. Through the sleeve design of the shaft housing 29 and the central shaft 28, and the use of sealed bearings for installation, it not only ensures that the main shaft can rotate smoothly to drive the mixing, but also achieves dynamic sealing at the top of the mixing tank 1 to prevent material leakage. Its function is to form the main structure of the equipment and the foundation for power transmission. The selection of the sealed bearings must be compatible with the chemical properties of automotive brake fluid to ensure long-term operation without corrosion or leakage.

[0030] refer to Figure 1-8In this embodiment, a drive assembly 4 for driving the main shaft assembly 3 to rotate is fixedly installed at the top of the mixing tank 1 corresponding to the main shaft assembly 3. The drive assembly 4 includes a drive motor 9, a drive gear 10 and a transmission gear 11. The drive motor 9 is fixedly installed at the top of the mixing tank 1, the drive gear 10 is fixedly installed at the output shaft end of the drive motor 9, and the transmission gear 11 is fixedly installed at the top of the shaft housing 29. The drive gear 10 and the transmission gear 11 mesh with each other.

[0031] In practice, the drive motor 9 drives the gear 10 pair to rotate the main shaft assembly 3, so that the power of the drive motor 9 is efficiently and stably transmitted to the main shaft assembly 3. The gear transmission method has a compact structure and transmits a large torque, which can ensure that the main shaft obtains sufficient rotational power to drive the internal complex mechanism. Its function is to provide the core driving force for the entire stirring system. The meshing clearance between the drive gear 10 and the transmission gear 11 needs to be adjusted properly and lubricating grease should be added regularly to ensure smooth transmission, low noise and low wear.

[0032] refer to Figure 1-8 In this embodiment, a positioning component 5 is fixedly installed on the top of the mixing tank 1. The positioning component 5 includes a mounting frame 12, an adjusting component 13, a positioning block 14, and an annular wave groove 15. The mounting frame 12 is fixedly installed on the top of the mixing tank 1. The adjusting component 13 is disposed on the top of the mounting frame 12. The bottom end of the adjusting component 13 is fixedly connected to the top of the positioning block 14. The annular wave groove 15 is formed on the surface of the positioning block 14.

[0033] In practice, as a fixed "track template", the annular wave groove 15 on it regulates the movement trajectory of the driven component 6. It provides a non-rotational, fixed spatial curve reference for dynamically adjusting the angle of the stirring blade 8. Its function is to transform the static support positioning into a dynamic control source for the movement of the stirring blade 8. The mounting bracket 12 needs to be firmly welded or fixed to the top of the tank to ensure that the annular wave groove 15 is absolutely stationary and does not shift during operation, so as to ensure control accuracy.

[0034] refer to Figure 1-8In this embodiment, a driven component 6 is movably installed inside the spindle assembly 3. The top end of the driven component 6 extends to and is movably connected to the positioning component 5. The driven component 6 includes a driven rod 20, a driven toothed groove 21, a limiting seat 22, a driving ring 23, a driving rod 24, and a driving head 25. The limiting seat 22 is fixedly installed on the surface of the central shaft 28 between the shaft housing and the central shaft 28. The driven rod 20 is in contact with the surface of the central shaft 28, and the limiting seat 22 is movably sleeved on the surface of the driven rod 20. The shafts 28 are parallel to each other. The driven tooth groove 21 is opened on the side of the driven rod 20. The driving ring 23 is movably sleeved on the surface of the central shaft 28 and located inside the shaft housing. The top end of the driven rod 20 is fixedly connected to the lower surface of the driving ring 23. The bottom end of the driving rod 24 is fixedly connected to the top end of the driving ring 23. The top end of the driving rod 24 passes through the shaft housing and the transmission gear 11 and extends above the transmission gear 11. The driving head 25 is fixedly installed on the inner side of the driving rod 24 near the top end. The driving head 25 is movably inserted into the inside of the annular wave groove 15.

[0035] In practical implementation, when the main spindle assembly 3 drives the driven assembly 6 to revolve, the top drive head 25 is constrained by the fixed annular wave groove 15, forcing it to generate axial up-and-down reciprocating motion. This motion is transmitted to the driven rod 20 through the drive rod 24 and drive ring 23. It cleverly transforms the rotational motion of the main spindle into the precise linear reciprocating motion of the driven rod 20, and is the core mechanism for motion conversion. Its function is to receive the extrusion force from the wave groove shape of the positioning assembly 5 and transmit this force to the rotating assembly 7. The limit seat 22 must ensure that the driven rod 20 can only slide axially and cannot rotate on its own, ensuring the correct meshing relationship between the driven tooth groove 21 and the rotating gear 27. The fit between the drive head 25 and the annular wave groove 15 must be smooth to reduce wear.

[0036] refer to Figure 1-8 In this embodiment, a rotating assembly 7 is rotatably mounted on the surface of the main shaft assembly 3 inside the mixing tank 1. The rotating assembly 7 meshes with the driven assembly 6. A stirring blade 8 is fixedly mounted on the side section of the rotating assembly 7. The rotating assembly 7 includes a rotating shaft 26 and a rotating gear 27. The rotating shaft 26 is rotatably mounted on the surface of the central shaft 28. One end of the rotating shaft 26 passes through the shaft-shaped housing 29 and extends to the outside of the shaft-shaped housing 29. The end of the rotating shaft 26 located outside the shaft-shaped housing 29 is fixedly connected to one end of the stirring blade 8. The rotating gear 27 is fixedly sleeved on the surface of the rotating shaft 26 located between the shaft-shaped housing 29 and the central shaft 28. The rotating gear 27 meshes with the driven tooth groove 21.

[0037] In practice, the reciprocating motion of the driven rod 20 drives the rotating gear 27 to rotate alternately in both directions through the driven tooth groove 21 on its side. This causes the rotating shaft 26 and the stirring blade 8 to oscillate around their own axis, ultimately converting the linear reciprocating motion into the rotational motion of the stirring blade 8. This achieves dynamic angle adjustment of the stirring blade 8 during its revolution. Its function is to act as the final actuator, directly acting on the material to generate the required complex fluid motion. The rotational connection between the rotating shaft 26 and the shaft housing 29 must be sealed to prevent material from seeping into the internal mechanism. The connection between the stirring blade 8 and the rotating shaft 26 must be tight to withstand alternating torque.

[0038] Example 2 refer to Figure 1-8 In this embodiment, the adjustment assembly 13 includes an adjustment knob 16, a fixing screw 17, a positioning cylinder 18, and a movable block 19. The adjustment knob 16 is rotatably mounted on the top of the mounting bracket 12. The positioning cylinder 18 is fixedly mounted on the top of the inner wall of the mounting bracket 12. The movable block 19 is fixedly mounted on the top of the positioning block 14, with the positioning cylinder 18 movably sleeved on the top of the movable block 19. The fixing screw 17 is fixedly mounted on the top of the movable block 19, and passes through the adjustment knob 16 and extends to the top of the adjustment knob 16. Above, the adjusting knob 16 is threaded onto the surface of the fixed screw 17. There are five sets of driven rods 20, five sets of rotating components 7 and stirring blades 8. The positions of the driven rods 20 correspond to the positions of the rotating components 7 and stirring blades 8. The five sets of driven rods 20, rotating components 7 and stirring blades 8 are arranged in a ring array with the central axis 28 as the array center. There are two sets of driving rods 24. The two sets of driving rods 24 are arranged axially symmetrically. The two sets of driving heads 25 are movably inserted into the inside of the annular wave groove 15.

[0039] In specific implementation, this section details the mechanical structure of the adjustment component 13 and clarifies the quantity and layout of each component. The adjustment component 13 raises and lowers as a whole by rotating the adjustment knob 16, causing the threaded fixed screw 17 to drive the movable block 19 and the positioning block 14. This allows the operator to easily adjust the initial tilt angle of all the stirring blades 8, thereby changing the basic flow field mode of the stirring and enhancing the process flexibility. The five sets are arranged in a ring array to ensure the uniformity of the stirring action within the tank. Its function is to macroscopically and holistically preset and adjust the stirring mode. During adjustment, it should be ensured that the two driving heads 25 on both sides are always kept within the annular wave groove 15 to avoid dislodging. After adjustment, the adjustment knob 16 should be locked or a locking device should be installed to prevent the positioning block 14 from being accidentally displaced due to equipment vibration.

[0040] The working principle of this invention is: The drive motor 9 is a stirring motor powered by the municipal power supply system. When the drive motor 9 is turned on, it drives the transmission gear 11 to rotate via the drive gear 10. The rotation of the transmission gear 11 drives the shaft housing 29 to rotate, which in turn drives the central shaft 28 to rotate synchronously. At this time, the rotation of the shaft housing 29 drives the rotating shaft 26 and the rotating gear 27 on the rotating assembly 7 to rotate synchronously around the central shaft 28. The rotation of the rotating shaft 26 around the central shaft 28 drives the stirring blade 8 to rotate around the central shaft 28, thereby mixing and stirring the automotive brake fluid in the mixing tank 1 through the stirring blade 8. During the stirring process, since the positioning assembly 5 is stationary, the driven assembly 6 rotates synchronously with the central shaft 28. During the rotation of the driven assembly 6, the head 25 rotates and moves within the annular wave groove 15. Since the annular wave groove 15 is as follows... Figure 7 As shown in the figure, the drive head 25 is squeezed by the annular wave groove 15 to form an up-and-down undulating motion. The up-and-down undulating motion of the drive head 25 drives the drive ring 23 to move up and down along the central axis 28 via the drive rod 24. The up-and-down undulating motion of the drive ring 23 drives the driven rod 20 to move up and down along the limit seat 22. The up-and-down undulating motion of the driven rod 20 drives the rotating gear 27 to rotate via the driven tooth groove 21. The rotation of the rotating gear 27 drives the rotating shaft 26 to rotate. The rotation of the rotating shaft 26 drives the stirring blade 8 to rotate. In this way, the tilt angle of the stirring blade 8 can be adjusted during the stirring process, thereby changing the stirring mode and further increasing the mixing effect. By rotating the adjustment knob 16, the fixed screw 17 is moved up and down. The up-and-down movement of the fixed screw 17 drives the positioning block 14 to move up and down via the movable block 19. The up-and-down movement of the positioning block 14 drives the entire driven assembly 6 to move up and down via the annular wave groove 15. The up-and-down movement of the driven assembly 6 changes the initial tilt angle of the stirring blade 8, further achieving the purpose of adjusting the tilt angle of the stirring blade 8.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
