Description

Technical Field

[0001] This invention relates to the technical field of stirring and mixing devices, and more specifically, to a high-efficiency stirring device. Background Technology

[0002] Agitators are one of the most common production equipment in industrial manufacturing, mainly used for mixing and reacting liquids and solids. Common agitators generally use impellers to stir the mixture, allowing different materials within the mixture to come into full contact with each other, thereby achieving better mixing or reaction results.

[0003] For situations where mixing is difficult or relies on efficient mixing, the common practice is to increase the impeller speed or extend the stirring time. However, such methods are sometimes inefficient. For example, in phosphoric acid production, efficient mixing is required. If insufficient liquid displacement or shearing occurs in parts of the mixture, the internal components cannot rotate sufficiently, leading to crystallization. Crystallization significantly reduces reaction efficiency. Such high-precision mixing requirements cannot usually be met by simply increasing the speed and extending the stirring time.

[0004] Therefore, designing a more efficient mixing device can better meet higher mixing requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a highly efficient stirring device that has a better stirring and mixing effect.

[0006] The embodiments of the present invention are achieved through the following technical solutions: The efficient stirring device of the present invention includes a tank, a turbulence-inducing component disposed on the inner wall of the tank, and a driving device; the turbulence-inducing component includes a first baffle and a second baffle disposed directly below the first baffle; the lower end of the first baffle and the upper end of the second baffle are close to each other; the driving device is used to drive the first baffle and the second baffle to swing.

[0007] Furthermore, both the first baffle and the second baffle have multiple flow-disrupting holes.

[0008] Furthermore, the driving device includes a driving rod disposed inside the tank, a pair of U-shaped clamps disposed on the side wall of the driving rod, a first lever disposed at one end of the first baffle, and a second lever disposed at the end of the second baffle; both the first lever and the second lever are engaged in the clamps; the first baffle is rotatably connected to the inner wall of the tank via a first rotating shaft, and the second baffle is rotatably connected to the inner wall of the tank via a second rotating shaft.

[0009] Furthermore, the driving device also includes a driving ring located below the tank body, and a motor for driving the driving ring to rotate; the upper end face of the driving ring is wavy, and the lower end of the driving rod passes through the bottom wall of the tank body and abuts against the upper end face of the driving ring.

[0010] Furthermore, the first lever is located at the lower end of the first baffle, and the second lever is located at the upper end of the second baffle.

[0011] Furthermore, a first spring is provided at the end of the first baffle away from the first lever, and a second spring is provided at the end of the second baffle away from the second lever; both the first spring and the second spring are connected to the inner wall of the tank.

[0012] Furthermore, the lower end of the first baffle is positioned close to the central axis of the tank, and the upper end of the second baffle is positioned close to the central axis of the tank.

[0013] Furthermore, the flow-disrupting assembly comprises multiple components, which are distributed along the circumferential direction of the tank.

[0014] The technical solution of this invention has at least the following advantages and beneficial effects: The efficient stirring device of this invention discharges materials into a tank and then uses external paddles to agitate the liquid, causing it to rotate and mix within the tank. During the rotation of the liquid in the tank, the liquid near the tank body hits the first and second baffles. The first and second baffles turbulent the liquid, causing the liquid near the tank wall to come into contact with and exchange with the liquid in the center of the tank, improving the mixing effect. Furthermore, the first and second baffles form a V-shape, squeezing the liquid at the upper and lower ends of the tank wall towards the center. The squeezed liquid can be further mixed, and the flow rate difference between the squeezed liquid and the rest of the liquid is significant. This flow rate difference generates further turbulence, creating more and richer turbulence zones inside the tank. This allows the liquid to rotate slightly within the tank, which is particularly important for phosphoric acid production, as maintaining a slight rotation of the internal liquid is crucial to effectively prevent crystallization.

[0023] Example

[0024] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 - Appendix Figure 7As shown, the efficient stirring device of this embodiment includes a tank 10, a flow-turbulence assembly disposed on the inner wall of the tank 10, and a driving device. The flow-turbulence assembly includes a first baffle 21 and a second baffle 26 disposed directly below the first baffle 21. The lower end of the first baffle 21 and the upper end of the second baffle 26 are close to each other. The driving device is used to drive the first baffle 21 and the second baffle 26 to swing. Specifically, in use, the material is discharged into the tank 10, and then an external blade is used to stir the liquid (since the blade is external and not part of this device, it is not shown in the figure), causing it to rotate and mix in the tank 10. During the rotation of the liquid in the tank 10, the liquid near the tank 10 will hit the first baffle 21 and the second baffle 26. The first baffle 21 and the second baffle 26 play a turbulence role on the liquid, so that the liquid near the wall of the tank 10 is disturbed and comes into contact with and exchanges with the liquid in the center of the tank 10, improving the mixing effect. Furthermore, the first baffle 21 and the second baffle 26 form a figure-eight shape, which can squeeze the liquid at the upper and lower ends of the tank wall 10 towards the middle. The squeezed liquid can be further mixed, and the liquid in the squeezed state has a large flow rate difference with the rest of the liquid. The flow rate difference will generate turbulence in the liquid again, thereby forming more and richer turbulence areas inside the tank 10. This can make the liquid generate a small rotation inside the tank 10 as much as possible. Especially for phosphoric acid production, it is necessary to keep the internal liquid in a small rotation to effectively avoid crystallization.

[0025] In this embodiment, both the first baffle 21 and the second baffle 26 have multiple flow-disrupting holes 22. Specifically, when the liquid passes through the flow-disrupting holes 22, its flow velocity will change significantly (the flow velocity increases). After passing through the flow-disrupting holes 22, the difference in flow velocity between the liquid and the surrounding liquid will result in a better mixing effect at this point.

[0026] The driving device in this embodiment includes a driving rod 31 disposed inside the tank 10, a pair of U-shaped clamping plates 32 disposed on the side wall of the driving rod 31, a first lever 24 disposed at one end of the first baffle 21, and a second lever 28 disposed at the end of the second baffle 26; both the first lever 24 and the second lever 28 are engaged in the clamping plates 32; the first baffle 21 is rotatably connected to the inner wall of the tank 10 via a first rotating shaft 23, and the second baffle 26 is rotatably connected to the inner wall of the tank 10 via a second rotating shaft 27. The driving device also includes a driving ring 33 disposed below the tank 10, and a motor 34 for driving the driving ring 33 to rotate; the upper end surface of the driving ring 33 is wavy, and the lower end of the driving rod 31 passes through the bottom wall of the tank 10 and abuts against the upper end surface of the driving ring 33. The first lever 24 is disposed at the lower end of the first baffle 21, and the second lever 28 is disposed at the upper end of the second baffle 26. Specifically, when the motor 34 drives the drive ring 33 to rotate, the wave-like shape of the upper surface of the drive ring 33 causes the drive rod 31 to reciprocate up and down. This, in turn, causes the clamping plate 32 and the first lever 24 and second lever 28 to oscillate the first baffle 21 and the second baffle 26, allowing the first lever 24 and the second lever 28 to also act as paddles, thus separately agitating the liquid on the wall of the tank 10. This significantly improves the agitation effect of the liquid.

[0027] In this embodiment, a first spring 25 is provided at the end of the first baffle 21 away from the first lever 24, and a second spring 29 is provided at the end of the second baffle 26 away from the second lever 28; both the first spring 25 and the second spring 29 are connected to the inner wall of the tank 10. Specifically, the springs ensure that even if the motor 34 is not turned on, the first spring 25 will still be connected to the second lever 28.

[0028] The first baffle 21 and the second baffle 26 can also be in a slight 5-swing state under the push of the liquid and the elastic force of the spring. It should be noted that there needs to be a certain amount of liquid between the clamp 32 and the first lever 24 and the second lever 28.

[0029] In this embodiment, the lower end of the first baffle 21 is positioned close to the central axis of the tank body 10, and the upper end of the second baffle 26 is positioned close to the central axis of the tank body 10. Specifically, see attached... Figure 3 As shown, this is the first gear.

[0030] Plate 21 and the second baffle 26 can squeeze the liquid at the edge toward the center, and the gap distance between the first baffle 21 and the second baffle 26 and the inner wall of the tank 10 is not the same everywhere, so that when the liquid passes through the gap between the first baffle 21, the second baffle 26 and the inner wall of the tank 10, a certain degree of turbulence can also be generated.

[0031] In this embodiment, multiple turbulence-disrupting components are provided, and these components are distributed along the circumference of the tank 10. Specifically, the dense distribution of multiple turbulence-disrupting components on the inner wall of the tank 10 can effectively improve the turbulence-disrupting effect.

[0032] In summary, the efficient stirring device of this embodiment discharges the material into the tank 10 during use, and then uses external paddles to stir the liquid, causing it to rotate and mix within the tank 10. During the rotation of the liquid within the tank 10, the portion of the liquid near the tank 10 will hit the first baffle 21 and...

[0033] On the second baffle 26, the first baffle 21 and the second baffle 26 turbulently affect the liquid, causing the liquid near the wall of the tank 10 to be disturbed and come into contact with and exchange with the liquid at the center of the tank 10.

[0034] To improve the mixing effect, the first baffle 21 and the second baffle 26 form a figure-eight shape, which can squeeze the liquid at the upper and lower ends of the tank wall 10 towards the middle. The squeezed liquid can be further mixed, and the liquid in the squeezed state has a large flow rate difference with the rest of the liquid. The flow rate difference will generate liquid turbulence again, thereby forming more and richer turbulence areas inside the tank 10. This can make the liquid generate a small rotation inside the tank 10 as much as possible. Especially for phosphoric acid production, it is necessary to keep the internal liquid in a small rotation to effectively avoid crystallization.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
