Description

Technical Field

[0001] This application relates to the field of reactive powder concrete preparation technology, and in particular to a method for preparing electrical components using reactive powder concrete. Background Technology

[0002] Power components refer to the parts of power equipment and electrical systems used in power systems, typically including equipment for power transmission, distribution, control, and protection. Power components are widely used in power systems and electrical equipment, and are an indispensable part of them.

[0003] The electrical components in this application specifically refer to precast concrete installation components, such as cement poles and substation mounting bases. Cement poles and substation mounting bases are typically precast from ordinary concrete. However, ordinary concrete has several drawbacks, both in its preparation and use. For example, ordinary concrete has low compressive strength, is brittle, and is prone to cracking under heavy loads; it also has poor durability, easily succumbing to environmental factors such as aging, cracking, and spalling; and its preparation process generates significant environmental pollution, producing large amounts of waste gas, wastewater, and solid waste.

[0004] Therefore, it is necessary to select new materials with superior mechanical properties and better durability when manufacturing power components. Compared with ordinary concrete, reactive powder concrete has better compressive strength, stronger durability, and less environmental pollution during the manufacturing process. Therefore, reactive powder concrete is selected to manufacture power components.

[0005] The preparation of reactive powder concrete requires thorough mixing to ensure its uniformity and density, thereby guaranteeing high compressive strength and durability. Before preparing reactive powder concrete, test blocks need to be prepared in a laboratory to test its physical properties. In the laboratory, manual mixing is typically used. However, the uniformity and density of the prepared reactive powder concrete are affected by the mixer's physical strength, experience, and other factors, making it difficult for the physical properties of the prepared concrete test blocks to meet testing requirements. Consequently, the physical properties of the resulting electrical components may not meet construction requirements.

[0006] Therefore, we propose a method for preparing electrical components using reactive powder concrete, which improves the mixing method of reactive powder concrete to ensure that the prepared electrical components meet construction requirements. Summary of the Invention

[0007] The purpose of this invention is to provide a method for preparing electrical components using reactive powder concrete, so as to solve the problem of difficulty in ensuring uniformity and density during the preparation of reactive powder concrete as mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A method for preparing electrical components using reactive powder concrete includes the following steps:

[0010] S1: Weigh the cement, silica fume, sand, and quartz powder according to the weight ratio, and put them into the mixer body separately. Dry mix for 1-3 minutes to make the materials evenly mixed.

[0011] The mixer body includes a mixing tank, a mixing mechanism disposed in the mixing tank for mixing the mixture, a power mechanism that drives the mixing tank to rotate in the opposite direction of the mixing mechanism, and a vibration mechanism that vibrates the outer peripheral wall of the mixing tank rotating in the opposite direction through the power mechanism.

[0012] S2: Add water and water-reducing agent, stir for 1-3 minutes. The mixing tank is equipped with a heating mechanism to heat the raw materials added to the mixing tank during the stirring process.

[0013] S3: Add cement again and stir for 3-5 minutes to fully mix all the raw materials. During this process, a heating device is also used to heat the raw materials.

[0014] S4: The mixed reactive powder concrete is poured into a test block mold and hydrated at a temperature of 22-28℃. On the first day of the hydration reaction, the ambient humidity around the mixing tank is controlled at 60-70%. On the second to third day of the hydration reaction, the ambient humidity around the mixing tank is controlled at 20-40%. The obtained test blocks are then tested.

[0015] S5: The stirred active powder concrete is poured into a special mold for preparing electrical components, and the hydration reaction is carried out under the temperature and humidity conditions in step S4.

[0016] S6: Remove the prepared reactive powder concrete from the special mold and cure it for one week.

[0017] By adopting the above technical solution, the mixing mechanism can fully mix various raw materials placed in the mixing tank. During this process, the mixing part of the mixing mechanism can move up and down while mixing in the mixing tank, thereby fully mixing raw materials at different depths, so that raw materials at different depths can be mixed together, making the mixing process more uniform.

[0018] During the mixing process, the mixing mechanism can drive the power mechanism to rotate, and the direction of rotation of the power mechanism is opposite to the mixing direction of the mixing mechanism, which further improves the mixing effect of the mixing mechanism on the mixture in the mixing box.

[0019] The power mechanism drives the vibration mechanism to vibrate automatically, causing the vibration mechanism to vibrate against the outer wall of the mixing tank. This, in conjunction with the mixing mechanism, makes the mixture more uniform. During the vibration process, air bubbles in the mixture are also removed, making the mixture more compact. This results in better uniformity and compactness of the test blocks, leading to better performance of the manufactured electrical components.

[0020] In a further embodiment, nano-alumina is added in step S1.

[0021] By adopting the above technical solution, nano-alumina, with its high specific surface area and activity, can react with the hydration products in cement to form hardened products, thereby improving the strength and durability of concrete.

[0022] Nano-alumina can also fill pores and microcracks in concrete, thereby improving the microstructure of reactive powder concrete and enhancing its density and durability.

[0023] In the preparation of reactive powder concrete, alkali-aggregate reaction is a common concrete defect, leading to cracking and embrittlement. Nano-alumina can react with alkaline substances in reactive powder concrete to form stable compounds, thereby inhibiting the occurrence of alkali-aggregate reaction.

[0024] Nano-alumina can also improve the durability of reactive powder concrete, making it more resistant to weathering, freeze-thaw cycles, and chemical erosion.

[0025] In summary, the addition of nano-alumina can improve the mechanical properties of reactive powder concrete, improve its microstructure, inhibit alkali-aggregate reaction, and enhance its durability.

[0026] In a further embodiment, the mixing tank is provided with an outer shell, and the mixing mechanism includes a mixing component, a driving component, and a linkage component;

[0027] The stirring assembly is disposed within the outer shell and the stirring part extends into the mixing tank, enabling it to mix and stir various raw materials within the mixing tank. Both the driving assembly and the linkage assembly are disposed within the outer shell, and the driving assembly can drive the stirring assembly to stir while the stirring part is repeatedly raised and lowered via the linkage assembly.

[0028] By adopting the above technical solution, when it is necessary to stir the mixture in the mixing tank, the drive component is activated. The drive component drives the stirring component to stir and lift at the same time through the linkage component, so as to improve the stirring effect of the concrete in the mixing tank, thereby improving the uniformity and density of the prepared reactive powder concrete, and thus improving the physical properties of the electrical components made of reactive powder concrete.

[0029] In a further embodiment, the stirring assembly includes a mounting base, a stirring shaft, and stirring blades. The mounting base is fixedly installed on the inner top wall of the outer shell. The stirring shaft slides through the mounting base and can move up and down along the height direction of the stirring tank. The stirring blades are installed on the stirring shaft and located at one end near the inner bottom wall of the stirring tank. The driving assembly can drive the stirring shaft to move up and down and rotate through the linkage assembly.

[0030] By adopting the above technical solution, when the drive component moves, it drives the linkage component to move, so that the linkage component drives the stirring shaft to rotate and simultaneously lifts and lowers, thereby enabling the stirring blades to stir and lift at the same time, thus achieving uniform stirring of the mixture in the mixing tank.

[0031] In a further embodiment, the stirring blade includes multiple blades, each of which has an adjustable rotation angle.

[0032] By adopting the above technical solution, when it is necessary to adjust the mixing force of the mixture, the installation angle of each blade can be adjusted to meet different usage requirements.

[0033] In a further embodiment, the drive assembly includes a drive member and a first worm gear. The drive member is mounted on the housing. The first worm gear is coaxially fixed to the output shaft of the drive member. A second worm gear is coaxially fixed to the stirring shaft. The rotation of the first worm gear can drive the second worm gear to rotate through the linkage assembly.

[0034] By adopting the above technical solution, when it is necessary to drive the stirring shaft to rotate and rise and fall, the driving component is activated. The driving component drives the first worm wheel to rotate, and the first worm wheel drives the second worm wheel to rotate through the linkage component. The second worm wheel drives the stirring shaft to rotate while rising or falling, thereby mixing materials of different depths more evenly.

[0035] In a further embodiment, the linkage component includes a first worm gear, a first rotating rod, a first connecting rod, a second worm gear, and a second rotating rod. The first worm gear and the second worm are both rotatably mounted on the inner top wall of the outer casing, and the first worm gear meshes with the first worm, and the second worm gear meshes with the second worm.

[0036] One end of the first rotating rod is fixed to the rotation axis of the first worm gear, and one end of the second rotating rod is fixed to the rotation axis of the second worm gear. The length of the first rotating rod is less than the length of the second rotating rod, and the two ends of the first connecting rod are rotatably connected to the other ends of the first rotating rod and the second rotating rod, respectively.

[0037] By adopting the above technical solution, when the driving component drives the first worm to rotate, the first worm will drive the first worm wheel to rotate, and the rotation of the first worm wheel will drive the first rotating rod to rotate. During the rotation of the first rotating rod, the second rotating rod will be driven to rotate through the first connecting rod, and the rotation of the second rotating rod will drive the second worm wheel to rotate, so that the second worm will drive the second worm to rotate, and the second worm will rise or fall while rotating, thereby realizing the rising or falling of the stirring blade during the stirring process.

[0038] In a further embodiment, the power mechanism includes a first gear, a second gear, a third gear, a fourth gear, a second connecting rod, a fifth gear, and an external gear ring. The first gear is coaxially sleeved and fixed to the outside of the first worm gear. The second gear is coaxially rotatably sleeved on the mounting base. The third gear is rotatably mounted on the inner top wall of the outer shell. The second connecting rod is rotatably mounted in the inner cavity of the outer shell. The fourth gear is sleeved and fixed to one end of the second connecting rod. The fifth gear is coaxially sleeved on the other end of the second connecting rod. The external gear ring is sleeved and fixed to the outer peripheral wall of the mixing tank.

[0039] The first gear, the second gear, the third gear, and the fourth gear mesh in sequence, and the fifth gear meshes with the external gear ring.

[0040] By adopting the above technical solution, when the driving component drives the first worm to rotate, the first worm will drive the first gear to rotate, the first gear will drive the second gear to rotate, the second gear will drive the third gear to rotate, the third gear will drive the fourth gear to rotate, the fourth gear will drive the second connecting rod to rotate, the second connecting rod will drive the fifth gear to rotate, and the fifth gear will drive the external gear ring to rotate, thereby driving the mixing box to rotate, so that the rotation direction of the mixing box and the mixing blades are opposite, thus making the relative mixing effect of the mixing blades better.

[0041] In a further embodiment, the vibration mechanism includes multiple sets of vibration components arranged circumferentially around the outer peripheral wall of the mixing tank and a vibrating element disposed on the second connecting rod. The second connecting rod can drive the vibrating element to rotate, so that the vibrating element drives each set of vibration components to vibrate sequentially.

[0042] By adopting the above technical solution, when the second rotating rod drives the vibrating component to rotate, the mixing box will also drive each set of vibrating components to rotate. When each set of vibrating components rotates to be directly opposite the vibrating component, the vibrating component will drive the vibrating component to vibrate, thereby vibrating the mixture in the mixing box. In conjunction with the stirring blades, air bubbles in the mixture can be eliminated, and during the vibration process, the various mixtures will be mixed more evenly, thereby improving the uniformity and density of the obtained reactive powder concrete, thus improving the physical properties of the obtained electrical components.

[0043] In a further embodiment, the vibration assembly includes a vibrating magnet and an elastic element. A plurality of mounting slots are provided circumferentially on the outer peripheral wall of the mixing tank. The vibrating magnet and the elastic element are both located in the mounting slots. One end of the elastic element is fixedly connected to the vibrating magnet, and the other end is fixedly connected to the inner wall of the mounting slot. The vibrating element is an active magnet, and the magnetic poles of adjacent vibrating magnets are opposite.

[0044] By adopting the above technical solution, during the rotation of the active magnet driven by the second rotating rod, the active magnet drives the vibrating magnet opposite it to move. When the magnetic poles of the active magnet and the vibrating magnet opposite it are the same, the active magnet drives the vibrating magnet to move away from the active magnet. At this time, the vibrating magnet causes the elastic element to deform. When the vibrating magnet rotates until it is no longer directly opposite the active magnet, under the elastic force of the elastic element, the vibrating magnet will oscillate repeatedly in the mounting groove, thereby applying a force to the outer peripheral wall of the mixing tank. Since the magnetic poles of adjacent vibrating magnets are opposite, the movement directions of adjacent vibrating magnets after passing the active magnet are exactly opposite, making the oscillation of each vibrating magnet on the mixing tank more obvious, thereby achieving vibration of the mixture to remove air bubbles and make the mixture more uniform.

[0045] Compared with the prior art, the beneficial effects of the present invention are:

[0046] 1. The mixing mechanism can fully mix various raw materials placed in the mixing tank. During this process, the mixing part of the mixing mechanism can move up and down while mixing in the mixing tank, so as to fully mix raw materials at different depths, so that raw materials at different depths can be mixed together, making the mixing process more uniform.

[0047] 2. During the mixing process, the mixing mechanism can drive the power mechanism to rotate, and the direction of rotation of the power mechanism is opposite to the mixing direction of the mixing mechanism, which further improves the mixing effect of the mixing mechanism on the mixture in the mixing box.

[0048] 3. Under the action of the power mechanism, the vibration mechanism will be driven to vibrate automatically, so that the vibration mechanism vibrates the outer peripheral wall of the mixing tank. This will work with the mixing mechanism to make the mixture more uniform. During the vibration process, the air bubbles in the mixture will also be removed, making the mixture more compact. This will result in better uniformity and compactness of the test blocks and better performance of the electrical components.

[0049] This invention provides a mixer with superior mixing performance. This mixer achieves more uniform and denser mixing of reactive powder concrete, resulting in electrical components with enhanced physical properties. Furthermore, the mixer in this invention uses only one drive unit for power, with all functions and effects achieved through various linkage mechanisms. The optimized design reduces the number of drive units, improves the linkage and integration between mechanisms, and reduces manufacturing costs while achieving better mixing results.

[0059] Combined with appendix Figure 1-5 This application will be described in further detail below.

[0060] This application discloses a method for preparing electrical components using reactive powder concrete.

[0061] A method for preparing electrical components using reactive powder concrete includes the following steps:

[0062] S1: Weigh the cement, silica fume, sand, quartz powder, and nano alumina according to the weight ratio and put them into the mixer body 1 respectively. The weight ratio of the cement, silica fume, sand, quartz powder, and nano alumina is 1:0.4:1.3:3.1:0.1. Dry mix for 1-3 minutes to make the materials evenly mixed.

[0063] S2: Add water and water-reducing agent in a weight ratio of 0.4:1, and stir the mixture for 1-3 minutes.

[0064] S3: Add cement again, at a ratio of 10% of the total weight, and stir again for 3-5 minutes to ensure that all raw materials are fully mixed.

[0065] S4: The mixed reactive powder concrete is poured into the test block mold and hydrated at a temperature of 22-28℃. On the first day of the hydration reaction, the ambient humidity around the mixing tank 2 is controlled at 60-70%. On the second to third day of the hydration reaction, the ambient humidity around the mixing tank 2 is controlled at 20-40%. The obtained test blocks are then tested.

[0066] S5: The stirred active powder concrete is poured into a special mold for preparing electrical components, and the hydration reaction is carried out under the temperature and humidity conditions in step S4.

[0067] The cement hydration reaction is a dynamic process; as time progresses, the hydration reaction continues, and the strength and hardening degree of the cement gradually increase. During the cement hydration reaction, the relationship between the strength of reactive powder concrete and time can be described using an exponential model in mechanical models. Where f(t) represents the cement strength at time t, and k3 and k4 are constants, representing the maximum value and growth rate of cement strength.

[0068] S6: Remove the prepared reactive powder concrete from the special mold for power components and cure it. After curing for one week, the required power components can be obtained.

[0069] The mixer body 1 in step S1 above includes a mixing tank 2, a heating mechanism, a stirring mechanism 3, a power mechanism 4, and a vibration mechanism 5. The heating mechanism is installed inside the mixing tank 2 and is used to heat the raw materials in steps S2-S3. The heating temperature is controlled within the range of 40-60℃.

[0070] Because reactive powder concrete generates friction during mixing, its viscosity increases. Heating during mixing can reduce the viscosity of reactive powder concrete, thereby improving mixing efficiency and uniformity.

[0071] Reference Figure 1 and Figure 2 The mixing tank 2 is covered with a fixed outer shell 21. The mixing tank 2 is equipped with a feeding mechanism 22 and a discharging mechanism 23. The raw materials enter the mixing tank 2 through the feeding mechanism 22. The raw materials entering the mixing tank 2 will be fully mixed under the stirring of the stirring mechanism 3. During the operation of the stirring mechanism 3, the stirring mechanism 3 can drive the power mechanism 4 to rotate the mixing tank 2 in the opposite direction of the stirring of the stirring mechanism 3, so that the raw materials in the mixing tank 2 can be more fully and evenly mixed.

[0072] During the operation of the power mechanism 4, the vibration mechanism 5 will be driven to vibrate, thereby vibrating and mixing the mixture in the mixing tank 2 and removing air bubbles from the mixture, thus improving the uniformity and density of the obtained active powder concrete.

[0073] The stirring mechanism 3, the power mechanism 4, and the vibration mechanism 5 are described in detail below:

[0074] Reference Figure 2 and Figure 3 The stirring mechanism 3 includes a stirring component 31, a driving component 32, and a linkage component 33. The stirring component 31 is located inside the outer shell 21 and the stirring part extends into the mixing tank 2, which can mix and stir various raw materials in the mixing tank 2. The driving component 32 and the linkage component 33 are both located inside the outer shell 21, and the driving component 32 can drive the stirring component 31 to stir while the stirring part is repeatedly raised and lowered through the linkage component 33.

[0075] Reference Figure 2 and Figure 3 The stirring assembly 31 includes a mounting base 311, a stirring shaft 312, and stirring blades. The mounting base 311 is fixedly installed on the inner top wall of the outer shell 21. The stirring shaft 312 slides through the mounting base 311 and can be raised and lowered along the height direction of the stirring box 2. It can also rotate freely while being raised and lowered. The stirring blades are installed on the stirring shaft 312 and are located at one end near the inner bottom wall of the stirring box 2. The stirring blades include multiple blades, and the rotation angle of each blade can be adjusted.

[0076] Reference Figure 3 The drive assembly 32 includes a drive component 321 and a first worm gear 322. The drive component 321 is a stepper motor. In other embodiments, a servo motor or a geared motor may also be used. This embodiment is only an example of a preferred method and is not the only implementation method.

[0077] The stepper motor is mounted on the housing 21. The first worm 322 is coaxially fixed with the output shaft of the stepper motor. The second worm is coaxially fixed on the stirring shaft 312. The rotation of the first worm 322 can drive the second worm to rotate through the linkage component 33.

[0078] Reference Figure 3 and Figure 4 The linkage component 33 includes a first worm gear 331, a first rotating rod 332, a first connecting rod 333, a second worm gear 334, and a second rotating rod 335. The first worm gear 331 and the second worm are both rotatably mounted on the inner top wall of the outer casing 21, and the first worm gear 331 and the first worm 322 are meshed, and the second worm gear 334 and the second worm are meshed.

[0079] One end of the first rotating rod 332 is fixed to the rotation axis of the first worm gear 331, and one end of the second rotating rod 335 is fixed to the rotation axis of the second worm gear 334. The length of the first rotating rod 332 is less than the length of the second rotating rod 335. The two ends of the first connecting rod 333 are rotatably connected to the other ends of the first rotating rod 332 and the second rotating rod 335, respectively.

[0080] When the stepper motor drives the first worm 322 to rotate, the first worm 322 will drive the first worm wheel 331 to rotate. The rotation of the first worm wheel 331 will drive the first rotating rod 332 to rotate. During the rotation of the first rotating rod 332, the second rotating rod 335 will be driven to rotate through the first connecting rod 333. The rotation of the second rotating rod 335 will drive the second worm wheel 334 to rotate, so that the second worm wheel 334 drives the second worm to rotate, and the second worm will rise or fall while rotating, thereby realizing the rising or falling of the stirring blade during the stirring process.

[0081] Reference Figure 3 and Figure 4 The power mechanism 4 includes a first gear 41, a second gear 42, a third gear 43, a fourth gear 44, a second connecting rod 45, a fifth gear 46, and an external gear ring 47. The first gear 41 is coaxially sleeved and fixed outside the first worm gear 322. The second gear 42 is coaxially rotatably sleeved on the mounting base 311. The third gear 43 is rotatably mounted on the inner top wall of the outer shell 21. The second connecting rod 45 is rotatably mounted in the inner cavity of the outer shell 21. The fourth gear 44 is sleeved and fixed at one end of the second connecting rod 45. The fifth gear 46 is coaxially sleeved at the other end of the second connecting rod 45. The external gear ring 47 is sleeved and fixed on the outer peripheral wall of the mixing tank 2.

[0082] The first gear 41, the second gear 42, the third gear 43, and the fourth gear 44 mesh in sequence, while the fifth gear 46 meshes with the external gear ring 47.

[0083] When the stepper motor drives the first worm gear 322 to rotate, the first worm gear 322 will drive the first gear 41 to rotate, the first gear 41 will drive the second gear 42 to rotate, the second gear 42 will drive the third gear 43 to rotate, the third gear 43 will drive the fourth gear 44 to rotate, the fourth gear 44 will drive the second connecting rod 45 to rotate, the second connecting rod 45 will drive the fifth gear 46 to rotate, and the fifth gear 46 will drive the external gear ring 47 to rotate, thereby driving the mixing box 2 to rotate, so that the rotation direction of the mixing box 2 and the mixing blade is opposite, thus making the relative mixing effect of the mixing blade better.

[0084] Reference Figure 3 and Figure 4 The vibration mechanism 5 includes a vibration assembly 51 and a vibration element 52. The vibration assembly 51 is arranged in multiple groups around the outer peripheral wall of the mixing tank 2. The vibration element 52 is fixedly installed on the second connecting rod 45. During the rotation of the second connecting rod 45, it can drive the vibration element 52 to rotate, so that the vibration element 52 drives each group of vibration assemblies 51 to vibrate in sequence.

[0085] Specifically, refer to Figure 4 and Figure 5 The vibration assembly 51 includes a vibration magnet 511 and an elastic element 512. The elastic element 512 is a spring, which is made of stainless steel. Multiple mounting slots are provided on the outer peripheral wall of the mixing tank 2 along the circumferential direction. The vibration magnet 511 and the spring are located in the mounting slots, and two springs are provided in each mounting slot. One end of each spring is fixedly connected to the vibration magnet 511, and the other end is fixedly connected to the inner wall of the mounting slot.

[0086] The vibrating element 52 is an active magnet. In this embodiment, both the vibrating magnet 511 and the active magnet are permanent magnets. When the second connecting rod 45 drives the active magnet to rotate, it will simultaneously drive the external gear ring 47 to rotate through the fifth gear 46. When the active magnet rotates, the mixing tank 2 will rotate together, so that each vibrating magnet 511 will rotate to the position directly opposite the active magnet in turn.

[0087] When the magnetic poles of the active magnet and the vibrating magnet 511 facing it are the same, the active magnet will drive the vibrating magnet 511 to move away from the active magnet. At this time, the vibrating magnet 511 will cause the elastic element 512 to deform. When the vibrating magnet 511 rotates until it is no longer facing the active magnet, under the elastic force of the elastic element 512, the vibrating magnet 511 will oscillate repeatedly in the mounting groove, thereby applying a force to the outer peripheral wall of the mixing tank 2.

[0088] The magnetic poles of adjacent vibrating magnets 511 are opposite, and the directions of movement of adjacent vibrating magnets 511 after passing the active magnet are exactly opposite, making the vibration of each vibrating magnet 511 on the mixing tank 2 more obvious, thereby achieving vibration of the mixture to remove air bubbles in the mixture and make the mixture more uniform.

[0089] The working principle of this embodiment is as follows: Start the stepper motor, the stepper motor drives the first worm 322 to rotate, the first worm 322 drives the first worm wheel 331 to rotate, the rotation of the first worm wheel 331 will drive the first rotating rod 332 to rotate, during the rotation of the first rotating rod 332, it will drive the second rotating rod 335 to rotate through the first connecting rod 333, the rotation of the second rotating rod 335 will drive the second worm wheel 334 to rotate, so that the second worm wheel 334 drives the second worm to rotate, and the second worm will rise or fall while rotating, thereby realizing the rising or falling of the stirring blade during the stirring process;

[0090] At the same time, when the stepper motor drives the first worm gear 322 to rotate, the first worm gear 322 will drive the first gear 41 to rotate, the first gear 41 will drive the second gear 42 to rotate, the second gear 42 will drive the third gear 43 to rotate, the third gear 43 will drive the fourth gear 44 to rotate, the fourth gear 44 will drive the second connecting rod 45 to rotate, the second connecting rod 45 will drive the fifth gear 46 to rotate, and the fifth gear 46 will drive the external gear ring 47 to rotate, thereby driving the mixing box 2 to rotate, so that the rotation direction of the mixing box 2 is opposite to that of the mixing blade. During the rotation of the mixing box 2, each vibrating magnet 511 will rotate to the position directly opposite to the active magnet in turn.

[0091] The second connecting rod 45 drives the active magnet to rotate, causing the vibrating magnet 511 to repeatedly move within the mounting groove, thereby vibrating the outer peripheral wall of the mixing tank 2, which in turn vibrates the mixture inside the mixing tank 2, thus improving the mixing effect.

[0092] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Furthermore, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This descriptive method is merely for clarity; those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
