Abstract
Description
Technical Field
[0001] This application relates to the field of mixing equipment technology, and in particular to a homogenizing device. Background Technology
[0002] With the development of the electrical age, the battery industry has ushered in a promising future. Among the current battery types, one widely used method involves coating the electrolyte slurry onto a tear-away steel side. This type of battery requires a very high viscosity of the electrolyte slurry.
[0003] High-speed homogenization systems have always been a core component in battery technology for adjusting electrolyte slurry viscosity. Current electrolyte slurry mixing equipment, i.e., homogenization devices, cannot adapt to different mixing speeds for operations such as mixing and kneading. This deficiency stems from the fact that the electrolyte slurry can withstand varying kneading forces at different mixing speeds, and these forces affect the slurry viscosity. Therefore, it is necessary to propose a new homogenization device that addresses the limitation of traditional homogenization devices in achieving different desired electrolyte slurry viscosities. Summary of the Invention
[0004] Therefore, it is necessary to propose a homogenizing device to address the shortcomings of traditional high-speed homogenizing systems, which have weak kneading capabilities and cannot match the viscosity of different desired electrolyte slurries.
[0005] This application provides a homogenizing apparatus, comprising:
[0006] A central cone, wherein the central cone is a cone;
[0007] Multiple blades, each blade is fixedly connected to the bottom of the central cone, and the multiple blades are evenly arranged in a circular shape around the central axis of the central cone;
[0008] Multiple stirring rods, with one stirring rod provided on the top surface of each blade, and the stirring rods being perpendicular to the bottom surface of the central cone;
[0009] The jet ring plate is fixedly connected to the edge of each blade. The jet ring plate is provided with multiple quadrilateral holes, and each quadrilateral hole is evenly arranged in a circular shape around the central axis of the central cone.
[0010] The homogenizing device also includes multiple flow-blocking plates;
[0011] Each baffle is fixedly mounted on the top surface of one blade;
[0012] Each of the flow-blocking plates is disposed between a stirring rod and the central cone;
[0013] The extension line of the flow-blocking plate in the height direction is perpendicular to the bottom surface of the central cone;
[0014] The opening area of each quadrilateral hole is different on the side closer to the central cone and on the side farther away from the central cone.
[0015] Furthermore, the opening area of the quadrilateral hole on the side closer to the central cone is greater than the opening area of the quadrilateral hole on the side farther from the central cone.
[0016] Furthermore, the opening area of the quadrilateral hole on the side closer to the central cone is smaller than the opening area of the quadrilateral hole on the side farther from the central cone.
[0017] Furthermore, each of the flow-blocking plates is provided with a jet hole;
[0018] The axis of each jet hole is located on the extension line of the radius of the jet ring plate, so that one side of each jet hole faces the central cone and the other side faces the inner ring surface of the jet ring plate.
[0019] The axis of each jet hole is parallel to the bottom surface of the central cone;
[0020] The axis of each jet hole is parallel to the bottom surface of the central cone.
[0021] Furthermore, the jet hole is a circular through hole.
[0022] Furthermore, the blades include a back blade and a front blade;
[0023] The back propeller is fixedly connected to the front propeller;
[0024] The front propeller has an inclined plane cross section;
[0025] The angle of the apex of the inclined plane is within the range of 20 degrees or greater and 40 degrees or less.
[0026] Furthermore, the stirring rod is a Mitsubishi prism;
[0027] The cross-section of the stirring rod along the horizontal plane is an isosceles triangle.
[0028] The extension of the altitude of the base of the isosceles triangle passes through the central axis of the central cone.
[0029] Furthermore, the quadrilateral hole is a parallelogram hole.
[0030] This application relates to a homogenizing device, comprising multiple blades fixedly connected to a central cone, with stirring rods mounted on the blades. A jet ring plate is fixedly connected to the edge of the blade ends. When the central cone drives the blades to rotate, the blades cause the electrolyte slurry to circulate. As the electrolyte slurry moves from the central cone towards the stirring rods, it impacts the stirring rods, dispersing the first portion of the electrolyte slurry. The second portion of the electrolyte slurry, under the cutting action of the blades, enters the bottom of the blades and undergoes a kneading action. The third portion of the electrolyte slurry, mixed with the electrolyte slurry dispersed by the stirring rods, passes through quadrilateral holes on the jet ring plate under centrifugal force, experiencing the kneading action of the quadrilateral holes. The kneading force of the quadrilateral holes can be achieved by selecting the shape of the openings on both sides of the holes (i.e., whichever has a larger opening area—the side closer to the central cone or the side farther from the central cone) to match the required kneading force of the electrolyte slurry and participate in the electrolyte slurry circulation. During the rotation of the blades, the electrolyte slurry circulates, which disperses and mixes the electrolyte slurry. The stirring rod disperses the electrolyte slurry, while the blades cut and knead it. These actions allow the homogenizing device to match different desired electrolyte slurry viscosities.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0039] This application provides a homogenizing device.
[0040] like Figure 1 As shown in one embodiment of this application, a homogenizing device includes a central cone 100, a paddle 200, a stirring rod 300, and a jet ring plate 400.
[0041] The central cone 100 is a cone.
[0042] Each blade 200 is fixedly connected to the bottom of the central cone 100, and the multiple blades 200 are evenly arranged in a circular shape around the central axis of the central cone 100.
[0043] Each blade 200 has a stirring rod 300 on its top surface, and the stirring rod 300 is perpendicular to the bottom surface of the central cone 100.
[0044] The jet ring plate 400 is fixedly connected to the edge of each blade 200. The jet ring plate 400 is provided with a plurality of quadrilateral holes 410, and each quadrilateral hole 410 is evenly arranged in a circular shape around the central axis of the central cone 100.
[0045] The homogenizing device also includes multiple baffles 500. Each baffle 500 is fixedly disposed on the top surface of a blade 200. Each baffle 500 is disposed between a stirring rod 300 and the central cone 100. The extension line of the height direction of the baffle 500 is perpendicular to the bottom surface of the central cone 100.
[0046] Specifically, electrolyte slurries with certain component formulations require strong dispersion to ensure that components that are difficult to mix thoroughly are evenly dispersed throughout the slurry. In this case, the electrolyte slurry needs to be circulated multiple times; high-speed circulation is more effective than kneading.
[0047] The height of the baffle plate 500 is relatively lower than that of the jet ring plate 400, which reduces the obstruction to the circulation of the electrolyte slurry and facilitates the high-speed circulation of the electrolyte slurry.
[0048] The central cone 100 can enable the blades 200 to rotate at a higher speed, thereby creating a larger electrolyte slurry circulation velocity.
[0049] The distance between the baffle plate 500 and the central axis of the central cone 100 can be one-third of the radius of the jet ring plate 400, which is beneficial for large particles in the electrolyte slurry to be blocked and dispersed by the baffle plate 500. The large stroke between the baffle plate 500 and the jet ring plate 400 allows the dispersed large particles of electrolyte slurry to quickly enter the bottom of the impeller 200 for kneading, ensuring that the large particles of electrolyte slurry are strongly and uniformly kneaded.
[0050] At the same time, the high-speed electrolyte slurry circulation can drive the kneaded electrolyte slurry to circulate, so that these slurries can participate in the next dispersion and kneading.
[0051] Furthermore, the opening area of the quadrilateral hole 410 on the side closer to the central cone is different from the opening area of the quadrilateral hole 410 on the side farther from the central cone. This allows the pinching force of the quadrilateral hole 410 to be achieved by selecting the shape of the openings on both sides of the quadrilateral hole 410.
[0052] This application relates to a homogenizing device. The device comprises multiple blades 200 fixedly connected to a central cone 100. A stirring rod 300 is mounted on each blade 200. A jet ring plate 400 is fixedly connected to the edge of the blade's end. When the central cone 100 rotates the blades, the blades 200 cause the electrolyte slurry to circulate. As the electrolyte slurry moves from the central cone 100 towards the stirring rod 300, it impacts the stirring rod 300, causing a first portion of the electrolyte slurry to be dispersed. A second portion of the electrolyte slurry, under the cutting action of the blades 200, enters the bottom of the blades 200 and undergoes a kneading action. The third part of the electrolyte slurry, mixed with the electrolyte slurry dispersed by the stirring rod 300, passes through the quadrilateral holes 410 on the jet ring plate 400 under centrifugal force. It is subjected to the kneading effect of the quadrilateral holes 410. The kneading force of the quadrilateral holes 410 can be achieved by selecting the shape of the openings on both sides of the holes (i.e., whichever is larger, the opening area on the side closer to the central cone 100 or the opening area on the side farther from the central cone 100) to match the required kneading force of the electrolyte slurry and participate in the electrolyte slurry circulation. During the rotation of the impeller 200, the electrolyte slurry circulates, which plays a role in dispersion and mixing. The stirring rod 300 disperses the electrolyte slurry, while the impeller 200 cuts and kneads it. These actions allow the homogenizing device to match different desired electrolyte slurry viscosities.
[0053] like Figure 3 As shown, in one embodiment of this application, the opening area of the quadrilateral hole 410 on the side closer to the central cone 100 is greater than the opening area of the quadrilateral hole 410 on the side farther from the central cone 100.
[0054] Specifically, in this embodiment, the opening area of the quadrilateral hole 410 on the side closer to the central cone 100 is greater than the opening area of the quadrilateral hole 410 on the side farther from the central cone 100.
[0055] The quadrilateral hole 410 has a larger opening area at the end near the central cone 100, which can receive a larger range of electrolyte slurry. The electrolyte slurry is kneaded through the quadrilateral hole 410, which is larger inside and smaller outside.
[0056] More specifically, the end of the quadrilateral hole 410 closest to the central cone 100 is the inner side of the quadrilateral hole 410, and the end of the quadrilateral hole 410 furthest from the central cone 100 is the outer side of the quadrilateral hole 410.
[0057] The quadrilateral orifice 410 can effectively suppress the edge effect of non-Newtonian fluid type electrolyte slurry, and the quadrilateral orifice 410 can be used to perform kneading on the flowing electrolyte slurry.
[0058] In one embodiment of this application, the opening area of the quadrilateral hole 410 at the end closer to the central cone 100 is smaller than the opening area of the quadrilateral hole 410 at the end farther from the central cone 100.
[0059] Specifically, this embodiment differs from the previous embodiment in that the opening area at the end closer to the central cone 100 is smaller than the opening area at the end of the quadrilateral hole 410 furthest from the central cone 100. This embodiment is not shown in the figures, but can be understood through reference. Figure 3 This is something that can be understood without question by those skilled in the art.
[0060] The quadrilateral hole 410, which is smaller inside and larger outside, is conducive to the formation of the electrolyte slurry in a jet state. The electrolyte slurry in the jet state is conducive to the dispersion of its own structure and also to increasing the circulation stroke, so that it can enter the kneading zone of the jet ring plate 400 and the blade 200.
[0061] In this embodiment, by setting a quadrilateral hole 410 with a smaller inner diameter and a larger outer diameter, the kneading area of the jet ring plate 400 and the paddle 200 is increased, which is beneficial to improving the efficiency of the homogenizing device in kneading electrolyte slurry.
[0062] like Figure 2 As shown, in one embodiment of this application, each of the flow-blocking plates 500 is provided with a jet hole 510. The axis of each jet hole 510 is located on the extension line of the radius of the jet ring plate 400, such that one side of each jet hole 510 faces the central cone 100, and the other side of each jet hole 510 faces the inner ring surface of the jet ring plate 400. The axis of each jet hole 510 is parallel to the bottom surface of the central cone 100.
[0063] Specifically, in this embodiment, each baffle plate 500 is provided with a jet hole 510. The baffle plate 500 itself will block part of the large particles of electrolyte slurry at the bottom. Increasing the jet hole 510 is beneficial to further improve the dispersion ability of the homogenizing device to knead the large particles of electrolyte slurry, enhance the participation in the circulation and kneading of electrolyte slurry.
[0064] When the axis of the jet orifice 510 is parallel to the bottom surface of the central cone 100, the electrolyte circulation direction through the jet orifice 510 is parallel to the bottom surface of the central cone 100, which can maintain a high circulation velocity.
[0065] Furthermore, providing jet holes 510 on the flow baffle 500 helps to reduce the accumulation of electrolyte slurry on the flow baffle.
[0066] In one embodiment of this application, the axis of the jet orifice 510 forms an angle with the bottom surface of the central cone 100. In this case, the jet orifice 510 is slightly skewed and not directly aligned with the central cone 100. When the axis of the jet orifice 510 forms an angle with the bottom surface of the central cone 100, the electrolyte circulation through the jet orifice 510 can form a unidirectional spiral, which is beneficial for improving the kneading effect of the homogenizing device.
[0067] like Figure 2 As shown, in one embodiment of this application, the jet hole 510 can be a circular through hole. The circular jet hole 510 utilizes the edge effect to disperse large-particle electrolyte slurry more quickly, which is beneficial to the full kneading of large-particle electrolyte slurry.
[0068] like Figure 4 As shown, in one embodiment of this application, the propeller 200 includes a back propeller 210 and a front propeller 220. The back propeller 210 is fixedly connected to the front propeller 220. The front propeller 220 has an inclined plane cross-section. The apex angle of the inclined plane is within the range of greater than or equal to 20 degrees and less than or equal to 40 degrees.
[0069] Specifically, the back propeller 210 can be used to mount the stirring rod 300 and the baffle plate 500. Meanwhile, the front propeller 220 has a sloping cross-section, allowing it to cut the electrolyte slurry and guide it to the bottom of the blade 200 for kneading. The back propeller 210 is fixedly connected to the sloping front propeller 220, which efficiently agitates the electrolyte slurry.
[0070] It is worth mentioning that the angle of the apex of the inclined plane is within the range of greater than or equal to 20 degrees and less than or equal to 40 degrees. As the angle of the apex of the inclined plane increases, the effect of guiding the electrolyte slurry to the bottom of the blade 200 will increase. As the angle of the apex of the inclined plane decreases, the effect of the front blade 220 in cutting and dispersing the electrolyte slurry will increase.
[0071] like Figure 4 As shown, in one embodiment of this application, the stirring rod 300 is a triangular prism. The cross-sectional shape of the stirring rod 300 along the horizontal plane is an isosceles triangle. The extension line of the altitude of the base of the isosceles triangle passes through the central axis of the central cone 100.
[0072] Specifically, the extension of the altitude of the base of the isosceles triangle passes through the central axis of the central cone 100. When the electrolyte slurry is subjected to centrifugal force, it will impact the side corresponding to the apex of the stirring rod 300. The stirring rod 300 will efficiently disperse the electrolyte slurry.
[0073] In one embodiment of this application, the quadrilateral hole 410 is a parallelogram hole. Figure 1 and Figure 2 This is an example of a parallelogram-shaped hole.
[0074] Specifically, a quadrilateral hole 410 is provided on the jet ring plate 400. During the establishment of the three-dimensional data model, when the diameter of the jet ring plate 400 is approximately 300 mm, the curvature of the jet ring plate 400 can enable the creation of a quadrilateral hole 410 with a draft angle on the curved wall of the jet ring plate 400. When the quadrilateral hole 410 has the data feature of a draft angle, it can achieve the effect of a quadrilateral hole 410 that is smaller inside and larger outside, or a quadrilateral hole 410 that is larger inside and smaller outside.
[0075] Alternatively, in one embodiment of this application, the quadrilateral hole 410 may also be a rectangular hole. Figure 3 This is an example of a rectangular hole. To better demonstrate rectangular holes and parallelogram holes, in Figure 1 and Figure 2 and Figure 3 The use of quadrilateral holes 410 of different shapes does not mean that a particular embodiment is limited to only one shape of quadrilateral hole. On the contrary, any embodiment of this application can use quadrilateral holes of any shape.
[0076] The technical features of the above embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
