Different slurry circulation speeds can be formed by different stirring speeds of the slurry. The included angle between the center axis of the center cone and the generatrix is larger than or equal to 10 degrees and smaller than or equal to 30 degrees, the higher the slurry circulation speed is, the smaller the included angle between the center axis of the center cone and the generatrix is, and smooth operation of the whole slurry circulation is facilitated. And the stopper and the through holes of the outer fence perform a stopping action on the circulation of the slurry, so that the paddle and the bottom of the shell perform a kneading procedure on the electrolyte slurry.

Description

Technical Field

[0001] The present application relates to the technical field of stirring equipment, and in particular to a mixing 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 traditional mixing device cannot efficiently adapt to the kneading requirements of the electrolyte slurry. The core reason for this problem is that different types of electrolyte slurries have different stirring speed requirements during the production process due to different formulas, and the traditional mixing device cannot efficiently adapt to the stirring requirements of the electrolyte slurry, and thus cannot efficiently knead the electrolyte slurry. For this reason, it is necessary to propose a mixing device to address the defect that the traditional mixing device cannot efficiently adapt to the kneading requirements of the electrolyte slurry. Summary of the invention

[0004] Based on this, it is necessary to propose a mixing device to address the defect that the traditional mixing device cannot efficiently adapt to the kneading requirements of the electrolyte slurry.

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

[0006] A central cone, wherein the central cone is a cone, and the angle between the central axis of the central cone and the generatrix is ​​within an angle range of greater than or equal to 10 degrees and less than or equal to 30 degrees;

[0007] A plurality of blades, each blade is fixedly connected to the bottom of the central cone, and the plurality of blades are evenly arranged circumferentially around the central axis of the central cone;

[0008] A plurality of blockers, each of which is provided with a blocker at the top of a blade, the number of blockers is equal to the number of blades and the blockers correspond to the blades one by one, and all blockers are evenly arranged circumferentially around the central axis of the central cone;

[0009] The outer fence is fixedly connected to the edge of each blade, and the outer fence is provided with a plurality of through holes, and all the through holes are evenly arranged circumferentially around the central axis of the central cone on the outer fence.

[0010] The present application relates to a mixing device, which realizes the stirring of the electrolyte slurry by rotating the paddle fixedly connected to the bottom of the central cone. Since the mixing device is arranged in a shell for accommodating the electrolyte slurry, the electrolyte slurry will form a circulation in the shell. Different slurry stirring speeds will form different slurry circulation speeds. The angle between the central axis of the central cone and the busbar is within an angle range of greater than or equal to 10 degrees and less than or equal to 30 degrees. The faster the slurry circulation speed, the smaller the angle between the central axis of the central cone and the busbar, which is conducive to the smooth operation of the entire slurry circulation. The through holes of the blocker and the outer fence perform a blocking action on the slurry circulation, so that the paddle and the bottom of the shell perform a kneading procedure on the electrolyte slurry. This solves the defect that the traditional mixing device cannot efficiently adapt to the kneading requirements of the electrolyte slurry. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] 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.

[0026] The present application provides a mixing device.

[0027] like Figure 1 As shown, in one embodiment of the present application, a mixing device includes a central cone 100, a plurality of paddles 200, a baffle 300 and an outer fence 400.

[0028] The central cone 100 is a cone, and the central axis 110 ( Figure 2 ) and busbar 120 ( Figure 2 The included angle is within the range of greater than or equal to 10 degrees and less than or equal to 30 degrees.

[0029] Each blade 200 is fixedly connected to the bottom of the central cone 100 , and a plurality of blades 200 are evenly arranged circumferentially around the central axis of the central cone 100 .

[0030] A blocker is disposed at the top of each blade 200 , the number of blockers 300 is equal to the number of blades 200 , and the blockers 300 and the blades 200 correspond one to one, and all blockers 300 are evenly arranged circumferentially around the central axis of the central cone 100 .

[0031] The outer fence 400 is fixedly connected to the edge of each blade 200 . The outer fence 400 is provided with a plurality of through holes 410 . All the through holes 410 are evenly arranged circumferentially around the central axis of the central cone 100 on the outer fence 400 .

[0032] Specifically, Figure 1 As shown, the plurality of through holes 410 provided on the outer fence 400 are rectangular through holes. The plurality of through holes 410 provided on the outer fence 400 may also be parallelogram through holes.

[0033] The present application relates to a mixing device, which realizes the stirring of the electrolyte slurry by rotating the paddle 200 fixedly connected to the bottom of the central cone 100. Since the mixing device is arranged in a shell for accommodating the electrolyte slurry, the electrolyte slurry will form a circulation in the shell. Different slurry stirring speeds will form different slurry circulation speeds. The angle between the central axis of the central cone 100 and the busbar 120 is within an angle range of greater than or equal to 10 degrees and less than or equal to 30 degrees. The faster the slurry circulation speed, the smaller the angle between the central axis of the central cone 100 and the busbar 120, which is conducive to the smooth operation of the entire slurry circulation. The through hole 410 of the blocker 300 and the outer fence 400 performs a blocking action on the slurry circulation, so that the paddle 200 and the bottom of the shell perform a kneading procedure on the electrolyte slurry. This solves the defect that the traditional mixing device cannot efficiently adapt to the kneading requirements of the electrolyte slurry.

[0034] In one embodiment of the present application, the angle between the central axis 110 of the central cone 100 and the generatrix 120 is equal to 10 degrees. The blocker 300 includes a first vertical rod 310. The first vertical rod 310 is perpendicular to the blade 200. The distance between the extension line of the height direction of the first vertical rod 310 and the central axis 110 of the central cone 100 is one third of the radius of the outer fence 400. The height direction of the first vertical rod 310 is parallel to the central axis 110 of the central cone 100.

[0035] Specifically, when the electrolyte slurry requires a greater kneading force, the central cone 100 can cause the blades 200 to rotate at a higher speed to form a higher electrolyte slurry circulation speed.

[0036] The distance between the first vertical rod 310 and the central axis of the central cone 100 is one third of the radius of the outer fence 400, which is conducive to the efficient dispersion of the electrolyte slurry at a low speed. The distance between the first vertical rod 310 and the outer fence 400 is large, and the dispersed electrolyte slurry can quickly enter between the blade 200 and the shell to knead the slurry.

[0037] Compared with other embodiments of the present application, the mixing device in this embodiment has weakened shearing ability and circulation ability, and the temperature rise of the slurry is slower, which is conducive to multiple mixing of high-speed electrolyte slurry in a low temperature environment.

[0038] 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.

[0039] This ensures that the electrolyte slurry that requires multiple strong kneading can be adapted to the kneading capacity of the mixing device, thereby solving the defect that the traditional mixing device cannot efficiently adapt to the kneading requirements of the electrolyte slurry.

[0040] In one embodiment of the present application, the angle between the central axis 110 of the central cone 100 and the generatrix 120 is equal to 10 degrees. The blocker 300 includes a first stirring blade 210. The first stirring blade 210 is arranged on the paddle 200. The extension line of the height direction of the first stirring blade 210 is perpendicular to the paddle 200. The distance between the extension line of the height direction of the first stirring blade 210 and the central axis 110 of the central cone 100 is one third of the radius of the outer fence 400. The height direction of the first stirring blade 210 is parallel to the central axis 110 of the central cone 100.

[0041] Specifically, some electrolyte slurries need to be dispersed strongly 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.

[0042] The height of the first stirring blade 210 is relatively low, and the obstruction to the circulation of the electrolyte slurry is small, which is conducive to the high-speed circulation of the electrolyte slurry.

[0043] The central cone 100 can make the blades 200 rotate at a higher rotation speed to form a higher electrolyte slurry circulation speed.

[0044] The distance between the extension line of the height direction of the first stirring blade 210 and the central axis 110 of the central cone 100 is one third of the radius of the outer fence 400, which is conducive to the large particles in the electrolyte slurry being blocked and dispersed by the first stirring blade 210. The stroke between the first stirring blade 210 and the outer fence 400 is large, and the dispersed large-particle electrolyte slurry can quickly enter between the blade 200 and the shell to knead the slurry, ensuring that the large-particle electrolyte slurry is strongly kneaded and uniform.

[0045] 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.

[0046] This ensures that the electrolyte slurry that needs to be dispersed multiple times can be adapted to the dispersing capacity of the mixing device, thereby solving the defect that the traditional mixing device cannot efficiently adapt to the kneading requirements of the electrolyte slurry.

[0047] like Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 An embodiment is an embodiment in which the angle between the central axis of the central cone and the generatrix is ​​equal to 10 degrees, and the embodiment has both a first vertical rod 310 and a first stirring blade 210 .

[0048] like Figure 2As shown, the bottom surface of the first stirring blade 210 is fixedly connected to the top surface of the blade 200, and the bottom surface of the first vertical rod 310 is fixedly connected to the top surface of the first stirring blade 210. At this time, the distance between the extension line of the height direction of the first vertical rod 310 and the central axis of the central cone 100 is equal to the distance between the extension line of the height direction of the first stirring blade 210 and the central axis of the central cone 100, both of which are one-third of the radius of the outer fence 400.

[0049] like Figure 3 As shown, Figure 3 This is a simulation diagram of the mixing device in this embodiment. Under a relatively low temperature environment, the mixing process of the electrolyte slurry can achieve a mixing effect. Intuitively, there is an orange-yellow effective mixing area at the through hole 410 of the outer fence 400. In the simulation parameters, an orange-yellow to red speed zone appears, which means that the effective mixing area can be determined.

[0050] like Figure 4 and Figure 5 As shown, in one embodiment of the present application, the angle between the central axis of the central cone 100 and the busbar 120 is equal to 20 degrees. The blocker 300 includes a second vertical rod 320 and a second stirring blade 220. The second vertical rod 320 is perpendicular to the blade 200. The distance between the extension line of the second vertical rod 320 in the height direction and the central axis 110 of the central cone 100 is two-thirds of the radius of the outer fence 400. The height direction of the second vertical rod 320 is parallel to the central axis 110 of the central cone 100. The height direction of the second stirring blade 220 is parallel to the central axis 110 of the central cone 100. The distance between the extension line of the height direction of the second stirring blade 220 and the central axis 110 of the central cone 100 is one-third of the radius of the outer fence 400.

[0051] Specifically, at this time, the second stirring blade 220 is equivalent to being disposed between the second stirring rod 320 and the central cone 100 , and part of the electrolyte slurry requires moderate dispersion and kneading to ensure strong adhesion of the finished electrolyte slurry.

[0052] More specifically, Figure 4 As shown, the top angle of the central cone 100 is changed from 10° to 20°, and the position of the second stirring blade 220 remains unchanged.

[0053] In this embodiment, the shear capacity of the mixing device becomes stronger and the circulation capacity becomes weaker. The circulation capacity can adapt to the inertia of large particles in the electrolyte slurry and reduce the impact damage of large particles in the electrolyte slurry on the entire device. After the shear capacity becomes stronger, the shear capacity of large particles in the electrolyte slurry can be increased.

[0054] The angle between the central axis of the central cone 100 and the busbar 120 is equal to 20 degrees, which is conducive to the continuous operation of a moderate electrolyte slurry circulation speed.

[0055] The distance between the second stirring blade 220 and the central axis of the central cone 100 is one third of the radius of the outer fence 400, which is conducive to the large particles in the electrolyte slurry being blocked and dispersed by the first stirring blade 210. The distance between the second stirring blade 220 and the outer fence 400 is large, and the dispersed large-particle electrolyte slurry can quickly enter between the blade 200 and the shell to knead the slurry, ensuring that the large-particle electrolyte slurry is strongly kneaded and uniform.

[0056] The distance between the second vertical rod 320 and the central axis of the central cone 100 is two-thirds of the radius of the outer fence 400, which is conducive to the efficient dispersion of the electrolyte slurry at a low speed. The distance between the second vertical rod 320 and the outer fence 400 is relatively narrow, and the dispersed electrolyte slurry can enter between the blade 200 and the shell to knead the slurry while maintaining a strong dispersion effect and speed.

[0057] like Figure 5 As shown, the second vertical bar 320 has a green block representing a higher speed, which is conducive to the efficient dispersion of the electrolyte slurry at a lower speed during the mixing process. In this simulation, the speed represented by the green block is lower than that of the orange area, which meets the working requirements of only dispersing but not mixing. Simply, large particle slurry needs to be dispersed first, which is conducive to the mixing process. And, it can be intuitively seen that the dispersion process occurs before the mixing process. Simply, the simulated flow field arrow points from the green block to the orange block.

[0058] In one embodiment of the present application, the angle between the central axis 110 of the central cone 100 and the generatrix 120 is equal to 30 degrees. The blocker 300 includes a third vertical rod 330. The third vertical rod 330 is perpendicular to the blade 200. The distance between the extension line of the height direction of the third vertical rod 330 and the central axis 110 of the central cone 100 is two-thirds of the radius of the outer fence 400. The height direction of the third vertical rod 330 is parallel to the central axis 110 of the central cone 100.

[0059] Specifically, some electrolyte slurries need to be temperature controlled during the kneading process to ensure the yield rate of the finished electrolyte slurry.

[0060] The angle between the central axis of the central cone 100 and the busbar 120 is equal to 30 degrees, which can adapt to a lower electrolyte slurry circulation speed.

[0061] While keeping the through hole 410 unchanged, increasing the top angle of the central cone 100 can enhance the circulation capacity.

[0062] The distance between the extension line of the third vertical rod 330 in the height direction and the central axis of the central cone 100 is two-thirds of the radius of the outer fence 400, which is conducive to the efficient dispersion of the electrolyte slurry at a low speed. The travel between the third vertical rod 330 and the outer fence 400 is relatively narrow, and the dispersed electrolyte slurry can enter between the blade 200 and the shell to knead the slurry while maintaining a strong dispersion effect and speed.

[0063] In one embodiment of the present application, the angle between the central axis 110 of the central cone 100 and the generatrix 120 is equal to 30 degrees. The blocker 300 also includes a third stirring blade 230. The third stirring blade 230 is arranged on the paddle 200. The height direction of the third stirring blade 230 is perpendicular to the paddle 200. The distance between the extension line of the height direction of the third stirring blade 230 and the central axis 110 of the central cone 100 is two-thirds of the radius of the outer fence 400. The height direction of the third stirring blade 230 is parallel to the central axis 110 of the central cone 100.

[0064] Some electrolyte slurries require 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 that of kneading. At the same time, the electrolyte slurry needs to be temperature-controlled during the kneading process to ensure the yield rate of the finished electrolyte slurry.

[0065] The distance between the third stirring blade 230 and the central axis of the central cone 100 is two-thirds of the radius of the outer fence 400, which is conducive to the large particles in the electrolyte slurry being blocked and dispersed by the third stirring blade 240. The distance between the third stirring blade 230 and the outer fence 400 is small, and the dispersed large-particle electrolyte slurry can enter between the blade 200 and the shell to knead the slurry, ensuring that the large-particle electrolyte slurry is strongly kneaded and uniform, while realizing the circulation of small-particle electrolyte slurry.

[0066] like Figure 6 and Figure 7 As shown, Figure 6 and Figure 7 The embodiment is an embodiment in which the angle between the central axis of the central cone 100 and the generatrix is ​​equal to 30 degrees, and the embodiment also has a third vertical rod 330 and a third stirring blade 230.

[0067] like Figure 6As shown, the bottom surface of the third stirring blade 230 is fixedly connected to the top surface of the blade 200, and the bottom surface of the third vertical rod 330 is fixedly connected to the top surface of the third stirring blade 230. At this time, the distance between the extension line of the height direction of the third vertical rod 330 and the central axis of the central cone 100 is equal to the distance between the extension line of the height direction of the third stirring blade 230 and the central axis of the central cone 100, both of which are one third of the radius of the outer fence 400.

[0068] like Figure 7 As shown, Figure 7 This is a simulation diagram of the mixing device in this embodiment. Part of the electrolyte slurry requires strong dispersion and can be strongly dispersed and kneaded in the red area.

[0069] like Figure 8 As shown, in one embodiment of the present application, the angle between the central axis 110 of the central cone 100 and the busbar 120 is equal to 30 degrees. The blocker 300 includes a fourth vertical rod 340 and a fourth stirring blade 240. The fourth vertical rod 340 is perpendicular to the blade 200. The distance between the extension line of the height direction of the fourth vertical rod 340 and the central axis 110 of the central cone 100 is two-thirds of the radius of the outer fence 400. The height direction of the fourth vertical rod 340 is parallel to the central axis 110 of the central cone 100. The height direction of the fourth stirring blade 240 is parallel to the central axis 110 of the central cone 100. The distance between the extension line of the height direction of the fourth stirring blade 240 and the central axis 110 of the central cone 100 is one-third of the radius of the outer fence 400.

[0070] Specifically, some electrolyte slurries need to control the temperature of the slurry circulation process to ensure the yield of the slurry.

[0071] The angle between the central axis of the central cone 100 and the busbar 120 is equal to 30 degrees, which is conducive to the continuous operation of a moderate electrolyte slurry circulation speed.

[0072] The distance between the extension line of the fourth stirring blade 240 in the height direction and the central axis of the central cone 100 is one third of the radius of the outer fence 400, which is conducive to the large particles in the electrolyte slurry being blocked and dispersed by the fourth stirring blade. The distance between the fourth stirring blade and the outer fence 400 is large, and the dispersed large-particle electrolyte slurry can quickly enter between the blade 200 and the shell to knead the slurry, ensuring that the large-particle electrolyte slurry is strongly kneaded and uniform.

[0073] The distance between the extension line of the fourth vertical rod 340 in the height direction and the central axis of the central cone 100 is two-thirds of the radius of the outer fence 400, which is conducive to the efficient dispersion of the electrolyte slurry, and the temperature change is small due to the reduced circulation speed. The distance between the fourth vertical rod 340 and the outer fence 400 is relatively narrow, and the dispersed electrolyte slurry can enter between the blade 200 and the shell to knead the slurry, while maintaining a strong dispersion effect and speed.

[0074] In order to intuitively understand the performance of different mixing devices, this application provides a performance parameter table.

[0075] Table 1: Performance parameters

[0076]

[0077]

[0078] The names and configurations of the mixing devices are as follows:

[0079] like Figure 2 and Figure 3 As shown, in improved type 1, the angle between the central axis 110 of the central cone 100 and the busbar 120 is equal to 10 degrees, the distance between the extension line of the first vertical rod 310 in the height direction and the central axis 110 of the central cone 100 is one third of the radius of the outer fence 400, and the distance between the extension line of the first stirring blade 210 in the height direction and the central axis 110 of the central cone 100 is one third of the radius of the outer fence 400.

[0080] like Figure 4 and Figure 5 As shown, in the improved type 2, the angle between the central axis 110 of the central cone 100 and the busbar 120 is equal to 20 degrees, the distance between the extension line of the second vertical rod 320 in the height direction and the central axis 110 of the central cone 100 is two-thirds of the radius of the outer fence 400, and the distance between the extension line of the second stirring blade 220 in the height direction and the central axis 110 of the central cone 100 is one-third of the radius of the outer fence 400.

[0081] like Figure 6 and Figure 7 As shown, in the improved type 3, the angle between the central axis 110 of the central cone 100 and the busbar 120 is equal to 30 degrees, the distance between the extension line of the third vertical rod 330 in the height direction and the central axis of the central cone 100 is two-thirds of the radius of the outer fence 400, and the distance between the extension line of the third stirring blade 240 in the height direction and the central axis 110 of the central cone 100 is two-thirds of the radius of the outer fence 400.

[0082] like Figure 8As shown, in improved type 4, the angle between the central axis 110 of the central cone 100 and the busbar 120 is equal to 30 degrees, the distance between the extension line of the fourth vertical rod 340 in the height direction and the central axis 110 of the central cone 100 is two-thirds of the radius of the outer fence 400, and the distance between the extension line of the fourth stirring plate in the height direction and the central axis of the central cone 100 is one-third of the radius of the outer fence 400.

[0083] It is worth mentioning that the characteristic parameters of shear capacity in Table 1 are average shear stress, maximum shear stress, average shear rate and maximum shear rate. Among them, shear stress is the force exerted by the mixing device on the electrolyte slurry. The shear rate is the distribution ratio of the amount of electrolyte slurry sheared and mixed in the electrolyte slurry to the whole electrolyte slurry when the mixing device acts on the electrolyte slurry.

[0084] The characteristic parameters of circulation capacity in Table 1 are top suction flow rate and material circulation rate. Among them, top suction flow rate is the capacity of the flow power source caused by the mixing device in the flow field of the electrolyte slurry. The material circulation rate is the circulation rate of the electrolyte slurry in the flow field by the mixing device.

[0085] The stirring power in Table 1 is the maximum power load that the mixing device can withstand under the position settings of the vertical rod of the stopper 300 of the mixing device and the stirring blades of the stopper 300.

[0086] From Table 1, under the condition of keeping the through hole 410 unchanged, increasing the top angle of the central cone 100 can enhance the circulation capacity.

[0087] The technical features of the above embodiments may be combined arbitrarily, 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 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.

[0088] The above 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.
