Description

Technical Field

[0001] The present application relates to the technical field of stirring equipment, and in particular to a homogenizing device. Background Art

[0002] With the development of the electrical age, the battery industry has ushered in a relatively positive development prospect. Among the current battery types, there is a type of battery that is used in large quantities: the electrolyte slurry is applied to one side of the hand-torn steel. This type of battery structure has high requirements for the viscosity of the electrolyte slurry.

[0003] The high-speed homogenization system in the battery field has always been the core device for adjusting the viscosity of the electrolyte slurry. The current electrolyte slurry stirring equipment, namely the homogenization device, cannot achieve functional adaptation of operations such as stirring and kneading at different stirring speeds. The reason for this defect is that the kneading force that the electrolyte slurry can bear is different at different stirring speeds, and different kneading forces will affect the viscosity of the electrolyte slurry. For this reason, it is necessary to propose a homogenization device to address the defect that the traditional homogenization device cannot match the different electrolyte slurry viscosities that are desired to be achieved. Summary of the invention

[0004] Based on this, it is necessary to propose a homogenization device to address the defect that the traditional high-speed homogenization system has weak kneading ability and cannot match the different desired electrolyte slurry viscosities.

[0005] The present application provides a homogenization device, comprising:

[0006] A central cone, wherein the central cone is a cone;

[0007] A plurality of blades, each blade being fixedly connected to the bottom of the central cone, and the plurality of blades being evenly arranged in a circle around the central axis of the central cone;

[0008] A plurality of stirring rods, each of the top surfaces of the blades is provided with a stirring rod, and the stirring rod is perpendicular to the bottom surface of the central cone;

[0009] A jet ring plate is fixedly connected to the edge of each blade, and the jet ring plate is provided with a plurality of quadrilateral holes, each of which is evenly arranged in a circle around the central axis of the central cone;

[0010] The homogenizing device also includes a plurality of baffles;

[0011] Each spoiler is fixedly arranged on the top surface of a blade;

[0012] Each of the baffles is disposed between a stirring rod and the central cone;

[0013] The extension line of the spoiler in the height direction is perpendicular to the bottom surface of the central cone;

[0014] The opening area of ​​each quadrilateral hole at a side close to the central cone is different from the opening area at a side far from the central cone.

[0015] Furthermore, an opening area of ​​a side of the quadrilateral hole close to the central cone is larger than an opening area of ​​a side of the quadrilateral hole far from the central cone.

[0016] Furthermore, an opening area of ​​a side of the quadrilateral hole close to the central cone is smaller than an opening area of ​​a side of the quadrilateral hole far from the central cone.

[0017] Furthermore, each of the spoiler plates is provided with a jet hole;

[0018] The hole 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 annular surface of the jet ring plate;

[0019] The hole axis of each jet hole is parallel to the bottom surface of the central cone;

[0020] The hole 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] Further, the paddles include a back paddle and a front paddle;

[0023] The back paddle is fixedly connected to the front paddle;

[0024] The cross section of the front paddle is an inclined surface;

[0025] The vertex angle of the inclined surface is within an angle range of greater than or equal to 20 degrees and less than or equal to 40 degrees.

[0026] Further, the stirring rod is a triangular prism;

[0027] The cross section of the stirring rod along the horizontal plane is in the shape of an isosceles triangle;

[0028] The extension line of the height 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] The present application relates to a homogenizing device, wherein a plurality of blades are fixedly connected through a central cone, a stirring rod is arranged on the blade, and the edge of the end of the blade is fixedly connected to a jet ring plate. When the central cone drives the blade to rotate, the blade drives the electrolyte slurry to form a circulation. In the process of the electrolyte slurry moving from the central cone to the stirring rod, the electrolyte slurry hits the stirring rod, so that the first part of the electrolyte slurry is dispersed. Under the cutting action of the blade, the second part of the electrolyte slurry enters the bottom of the blade to perform a kneading action. The third part of the electrolyte slurry is mixed with the electrolyte slurry dispersed by the stirring rod, and passes through the quadrilateral hole on the jet ring plate under the action of centrifugal force, and is kneaded by the quadrilateral hole. The kneading force of the quadrilateral hole can be achieved by selecting the opening shape of the two sides of the quadrilateral hole (that is, which one of the opening area close to the central cone and the opening area away from the central cone is larger) to adapt to the kneading force required by the electrolyte slurry and participate in the circulation of the electrolyte slurry. During the rotation of the paddles, the electrolyte slurry circulates, which disperses and mixes the electrolyte slurry. The stirring rod disperses the electrolyte slurry, and the paddles cut and knead the electrolyte slurry. These effects enable the homogenizing device to match the desired electrolyte slurry viscosity. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] The present application provides a homogenization device.

[0040] like Figure 1 As shown, in one embodiment of the present 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 of the blades 200 is fixedly connected to the bottom of the central cone 100 , and a plurality of blades 200 are evenly arranged in a circle around the central axis of the central cone 100 .

[0043] A stirring rod 300 is disposed on the top surface of each blade 200 , 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 . Each quadrilateral hole 410 is evenly arranged in a circle around the central axis of the central cone 100 .

[0045] The homogenizing device further comprises a plurality of 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, the electrolyte slurry under some component formulas needs strong dispersion to ensure that the components that are difficult to fully mix in the electrolyte slurry are evenly dispersed throughout the electrolyte slurry. At this time, the electrolyte slurry needs to be circulated multiple times, and the effect of high-speed circulation will be better than the effect of kneading.

[0047] The height of the baffle plate 500 is lower than that of the jet ring plate 400 , and has less obstruction to the circulation of the electrolyte slurry, which is conducive to the high-speed circulation of the electrolyte slurry.

[0048] The central cone 100 can make the blades 200 rotate at a higher rotation speed to form a higher electrolyte slurry circulation speed.

[0049] The distance between the spoiler 500 and the central axis of the central cone 100 may be one third of the radius of the jet ring plate 400, which is conducive to the large particles in the electrolyte slurry being blocked and dispersed by the spoiler 500. The distance between the spoiler 500 and the jet ring plate 400 is relatively large, and the dispersed large-particle electrolyte slurry can quickly enter the bottom of the blade 200 to knead the slurry, ensuring that the large-particle electrolyte slurry is strongly kneaded and uniform.

[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] In addition, the opening area of ​​the quadrilateral hole 410 close to the central cone is different from the opening area of ​​the quadrilateral hole 410 away from the central cone, so that the kneading force of the quadrilateral hole 410 can be achieved by selecting the opening shapes on both sides of the quadrilateral hole 410.

[0052] The present application relates to a homogenizing device, wherein a plurality of paddles 200 are fixedly connected through a central cone 100, a stirring rod 300 is arranged on the paddle 200, and the edge of the end of the paddle 200 is fixedly connected to a jet ring plate 400. When the central cone 100 drives the paddle to rotate, the paddle 200 drives the electrolyte slurry to form a circulation, and in the process of the electrolyte slurry moving from the central cone 100 to the stirring rod 300, the electrolyte slurry hits the stirring rod 300, so that the first part of the electrolyte slurry is dispersed. Under the cutting action of the paddle 200, the second part of the electrolyte slurry enters the bottom of the paddle 200 to perform a kneading action. The third part of the electrolyte slurry is mixed with the electrolyte slurry dispersed by the stirring rod 300, and passes through the quadrilateral hole 410 on the jet ring plate 400 under the action of centrifugal force, and is subjected to the kneading effect of the quadrilateral hole 410. The kneading force of the quadrilateral hole 410 can be achieved by selecting the opening shape on both sides of the quadrilateral hole 410 (i.e., which one of the opening area on the side close to the central cone 100 and the opening area on the side away from the central cone 100 is larger) to adapt to the kneading force required by the electrolyte slurry and participate in the circulation of the electrolyte slurry. During the rotation of the blade 200, the electrolyte slurry circulates, and the circulation plays a role of dispersion and mixing. The stirring rod 300 plays a role of dispersion on the electrolyte slurry, and the blade 200 plays a role of cutting and kneading on the electrolyte slurry. These effects enable the homogenizing device to match different electrolyte slurry viscosities that are desired to be achieved.

[0053] like Figure 3 As shown, in one embodiment of the present application, the opening area of ​​the quadrilateral hole 410 on the side close to the central cone 100 is larger than the opening area of ​​the quadrilateral hole 410 on the side away from the central cone 100 .

[0054] Specifically, in this embodiment, the opening area of ​​the side of the quadrilateral hole 410 close to the central cone 100 is larger than the opening area of ​​the side of the quadrilateral hole 410 far from the central cone 100 .

[0055] The opening area of ​​one end of the quadrilateral hole 410 close to the central cone 100 is larger, and can receive a larger range of electrolyte slurry, and the electrolyte slurry is kneaded through the quadrilateral hole 410 with a larger inner side and a smaller outer side.

[0056] More specifically, one end of the quadrilateral hole 410 close to the central cone 100 is the inner side of the quadrilateral hole 410 , and one end of the quadrilateral hole 410 away from the central cone 100 is the outer side of the quadrilateral hole 410 .

[0057] The quadrilateral holes 410 can effectively suppress the edge effect of the electrolyte slurry of the non-Newtonian fluid type, and the flowing electrolyte slurry can be kneaded by using the quadrilateral holes 410 .

[0058] In one embodiment of the present application, an opening area of ​​one end of the quadrilateral hole 410 close to the central cone 100 is smaller than an opening area of ​​one end of the quadrilateral hole 410 far from the central cone 100 .

[0059] Specifically, this embodiment is different from the previous embodiment. In this embodiment, the opening area of ​​the end close to the center cone 100 is smaller than the opening area of ​​the end of the quadrilateral hole 410 away from the center cone 100. This embodiment is not shown in the figure, but by reference Figure 3 Those skilled in the art can understand it without any doubt.

[0060] The quadrilateral hole 410 with a small inside and a large outside is conducive to the electrolyte slurry forming a spray state. The electrolyte slurry in the spray state is conducive to the dispersion of its own structure and is also conducive to increasing the circulation stroke and entering the kneading action area of ​​the jet ring plate 400 and the blade 200.

[0061] In this embodiment, by providing a quadrilateral hole 410 that is smaller inside and larger outside, the kneading action area of ​​the jet ring plate 400 and the blade 200 is increased, which is beneficial to improving the efficiency of the homogenizing device in kneading the electrolyte slurry.

[0062] like Figure 2 As shown, in one embodiment of the present application, each of the baffle plates 500 is provided with a jet hole 510. The hole axis of each of the jet holes 510 is located on the extension line of the radius of the jet ring plate 400, so that one side of each of the jet holes 510 faces the central cone 100, and the other side of each of the jet holes 510 faces the inner annular surface of the jet ring plate 400. The hole axis of each of the jet holes 510 is parallel to the bottom surface of the central cone 100.

[0063] Specifically, in this embodiment, each baffle 500 is provided with a jet hole 510. The baffle 500 itself will block part of the large-particle electrolyte slurry at the bottom. Adding the jet hole 510 is beneficial to further improve the dispersion ability of the homogenizing device to knead the large-particle electrolyte slurry and enhance the circulation and kneading effect of the electrolyte slurry.

[0064] When the hole axis of the jet hole 510 is parallel to the bottom surface of the central cone 100, the electrolyte circulation direction through the jet hole 510 is parallel to the bottom surface of the central cone 100. In this case, a relatively high circulation velocity can be maintained.

[0065] In addition, providing the jet holes 510 on the baffle plate 500 is also helpful in reducing the electrolyte slurry accumulated and adhered to the baffle plate.

[0066] In one embodiment of the present application, there is an angle between the hole axis of the jet hole 510 and the bottom surface of the central cone 100. At this time, the jet hole 510 is slightly deflected and is not directly facing the central cone 100. When there is an angle between the hole axis of the jet hole 510 and the bottom surface of the central cone 100, the electrolyte circulation through the jet hole 510 can form a unidirectional spiral, which is conducive to improving the kneading effect of the homogenizing device.

[0067] like Figure 2 As shown, in one embodiment of the present application, the jet hole 510 may be a circular through hole. The circular jet hole 510 utilizes the edge effect to disperse the large-particle electrolyte slurry faster, which is beneficial to the full kneading of the large-particle electrolyte slurry.

[0068] like Figure 4 As shown, in one embodiment of the present application, the blade 200 includes a back paddle 210 and a front paddle 220. The back paddle 210 is fixedly connected to the front paddle 220. The cross section of the front paddle 220 is an inclined plane. The angle of the top angle of the inclined plane is within an angle range of greater than or equal to 20 degrees and less than or equal to 40 degrees.

[0069] Specifically, the back paddle 210 can be used to install the stirring rod 300 and the spoiler 500. At the same time, the front paddle 220 has an inclined cross section, and the front paddle 220 can cut the electrolyte slurry and guide the electrolyte slurry to the bottom of the blade 200 for kneading. The back paddle 210 is fixedly connected to the front paddle 220 with an inclined cross section, which can efficiently disturb the electrolyte slurry.

[0070] It is worth mentioning that the angle of the top angle of the inclined surface is within the range of 20 degrees or more and 40 degrees or less. As the angle of the top angle of the inclined surface increases, the effect of guiding the electrolyte slurry to the bottom of the blade 200 increases. As the angle of the top angle of the inclined surface decreases, the effect of the front paddle 220 in cutting and dispersing the electrolyte slurry increases.

[0071] like Figure 4 As shown, in one embodiment of the present application, the stirring rod 300 is a triangular prism. The cross section of the stirring rod 300 along the horizontal plane is an isosceles triangle. The extension line of the height of the base of the isosceles triangle passes through the central axis of the central cone 100.

[0072] Specifically, the extended line of the height 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, the electrolyte slurry will hit the side corresponding to the vertex of the stirring rod 300. The stirring rod 300 will efficiently disperse the electrolyte slurry.

[0073] In one embodiment of the present application, the quadrilateral hole 410 is a parallelogram hole. Figure 1 and Figure 2 This is an example of a parallelogram hole.

[0074] Specifically, the quadrilateral hole 410 is provided on the jet ring plate 400. In the process of establishing the three-dimensional data model, when the diameter of the jet ring plate 400 is within the data range of about 300 mm, the curvature of the jet ring plate 400 can realize the establishment of the 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 the draft angle, the effect of the quadrilateral hole 410 that is small inside and large outside or the effect of the quadrilateral hole 410 that is large inside and small outside can be achieved.

[0075] Optionally, in an embodiment of the present application, the quadrilateral hole 410 may also be a rectangular hole. Figure 3 This is an example of a rectangular hole. In order to better demonstrate the rectangular hole and the parallelogram hole, Figure 1 and Figure 2 and Figure 3 The use of quadrilateral holes 410 of different shapes does not mean that a certain embodiment is limited to quadrilateral holes of only one shape. On the contrary, any embodiment of the present application can use quadrilateral holes of any shape.

[0076] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described 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 above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
