Battery slurry is a key factor in the entire battery electrode preparation process. The quality of the slurry affects the coating process and the final battery performance, so it is particularly important in the slurry stage. Usually, the battery slurry is formed by the active material, binder, and conductive agent being evenly dispersed in the solvent through the mechanical action of the stirring paddle and the dispersion disk in the stirring device, such as flipping, kneading, and shearing. The stirring of the ingredients is the basis of the subsequent process of lithium batteries, and high-quality stirring is the prerequisite for the high-quality completion of subsequent coating and rolling.

[0064] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0065] In some embodiments, a stirring device is provided, which can be applied to the field of battery production, and is used to stir the materials involved in the battery production process. For example, in the field of secondary batteries, in the manufacturing process of the battery, the preparation of positive electrode slurry and negative electrode slurry is involved, and the active material, binder, conductive agent and solvent are mixed together, and stirred with a stirring device to form a uniform electrode slurry. Of course, in addition to this, the stirring device can also be used in other fields, and the embodiments of the present application do not specifically limit the specific use scenarios and working conditions of the stirring device.

[0066] See also Figures 1 to 6As shown, in some embodiments, the stirring device provided includes: a stirring shell 100, a driving mechanism 200, a stirring mechanism 300, a first rotating shaft 500 and a second rotating shaft 600; the stirring shell 100 can be used to form a stirring space, the driving mechanism 200 can be used as a power source to provide power for the rotation of the stirring mechanism 300, etc., the stirring mechanism 300 can be used to stir the material so that the material is fully mixed and uniform, the two ends of the first rotating shaft 500 can be used to connect the output end of the driving mechanism 200 and one end of the stirring mechanism 300 respectively, the driving mechanism 200 drives the first rotating shaft 500 to rotate, the rotation of the first rotating shaft 500 can drive the stirring mechanism 300 to rotate, the second rotating shaft 600 can be used with the other end of the stirring mechanism 300, the second rotating shaft 600 can rotate with the first rotating shaft 500 and the stirring mechanism 300, and the second rotating shaft 600 can also play a role of stable support.

[0067] The stirring shell 100 includes a first wall 110 and a second wall 120 which are arranged at intervals, such as the first wall 110 and the second wall 120 are arranged at intervals in the up-down direction, and the first wall 110 is located above the second wall 120; further, the stirring shell 100 may also include a side wall arranged between the first wall 110 and the second wall 120, and the side wall may be a cylindrical structure, or a structure similar to a cylindrical structure, or a square cylindrical structure, and the upper and lower ends of the side wall are respectively connected to the first wall 110 and the second wall 120. Thus, by the arrangement of the first wall 110, the second wall 120 and the side wall, a stirring space can be formed, and the stirring mechanism 300 and the material to be stirred can be arranged in the stirring space.

[0068] The stirring mechanism 300 is disposed between the first wall 110 and the second wall 120 , that is, the stirring mechanism 300 is disposed in the stirring space to stir the material in the stirring space.

[0069] The first rotating shaft 500 is rotatably connected to the first wall 110, and one end of the first rotating shaft 500 extends out of the stirring shell 100, such as the upper end of the first rotating shaft 500 extends out of the first wall 110, and the upper end of the first rotating shaft 500 is transmission-connected to the driving mechanism 200, and the other end of the first rotating shaft 500 extends into the stirring shell 100 and is connected to the first end of the stirring mechanism 300, such as the lower end of the first rotating shaft 500 extends into the stirring shell 100 and is connected to the first end of the stirring mechanism 300, such as the top end of the stirring mechanism 300. Thus, the first rotating shaft 500 can be driven to rotate by the driving mechanism 200, and the rotation of the first rotating shaft 500 can drive the stirring mechanism 300 to rotate.

[0070] Optionally, the driving mechanism 200 is a driving motor. The output shaft of the driving motor can transmit power to the first rotating shaft 500 through a coupling, gear transmission, etc.

[0071] Of course, in other implementations, other driving modes known in the art may also be selected, and this embodiment is not limited to this.

[0072] The second rotating shaft 600 is rotatably connected to the second wall 120, and one end of the second rotating shaft 600 extends into the stirring shell 100 and is connected to the second end of the stirring mechanism 300; if the upper end of the second rotating shaft 600 extends into the stirring shell 100, the lower end of the second rotating shaft 600 can extend out of the stirring shell 100, that is, the upper and lower ends of the second rotating shaft 600 can be respectively located at the upper and lower sides of the second wall 120, and the upper end of the second rotating shaft 600 can be connected to the second end of the stirring mechanism 300. Therefore, the second rotating shaft 600 can rotate with the rotation of the first rotating shaft 500 and the stirring mechanism 300.

[0073] The first rotating shaft 500 and the second rotating shaft 600 are coaxially arranged, that is, the axis of the first rotating shaft 500 and the axis of the second rotating shaft 600 are colinearly arranged.

[0074] Therefore, based on the above settings, the stirring device provided in this embodiment is adopted, and the driving mechanism 200 such as a motor is used to drive the first rotating shaft 500 to rotate. The stirring mechanism 300 can be operated through the synergistic effect. With the support of the first rotating shaft 500 and the second rotating shaft 600, respectively, and the principle of the first rotating shaft 500 and the second rotating shaft 600 being coaxial, the splitting problem caused by the wear of the stirring shaft can be effectively prevented, and the deformation problem of the stirring paddle can be effectively avoided. That is, the occurrence of pain points such as the deformation of the stirring paddle caused by the splitting of the stirring shaft due to long-term use can be effectively prevented, and the undesirable problem of the stirring paddle scraping the tank wall due to deformation is alleviated, and the slurry has a good stirring and dispersing effect, which is beneficial to improving the quality of the slurry and improving the production efficiency and quality of the slurry.

[0075] In addition, in a preferred embodiment of the present application, a dispersion mechanism 400 and an extrusion assembly 380 are provided in the stirring shell 100. The dispersion mechanism 400 can adopt a double dispersion shaft setting method, and the extrusion assembly 380 can adopt a conical screw structure design method. Thus, by adopting the design of double dispersion shafts and conical screw structures, the stirring, extrusion and dispersion effects can be improved, the production efficiency can be improved, and the quality of the slurry can be further improved.

[0076] like Figure 1As shown, in some embodiments, the stirring device further includes a dispersion mechanism 400 arranged around the axis of the stirring mechanism 300, and the dispersion mechanism 400 includes a dispersion shaft 410 and a plurality of dispersion components 420; the dispersion shaft 410 is rotatably connected to the first wall 110 and the second wall 120 respectively, such as the upper end of the dispersion shaft 410 is rotatably connected to the first wall 110, and one end of the dispersion shaft 410, such as the top end, extends out of the stirring shell 100 and is transmission-connected to the driving mechanism 200, and the lower end of the dispersion shaft 410 is rotatably connected to the second wall 120; the plurality of dispersion components 420 are all arranged on the dispersion shaft 410 and are arranged at intervals along the axial direction of the dispersion shaft 410. The dispersion shaft 410 is arranged parallel to the first rotating shaft 500 and the second rotating shaft 600.

[0077] Optionally, there are multiple dispersing mechanisms 400, that is, the stirring device includes multiple dispersing mechanisms 400, and the multiple dispersing mechanisms 400 are all connected to the driving mechanism 200; the multiple dispersing mechanisms 400 are evenly distributed around the stirring mechanism 300, that is, the multiple dispersing mechanisms 400 are evenly arranged around the axis of the stirring mechanism 300, and the dispersing axes 410 in the multiple dispersing mechanisms 400 are all arranged parallel to the first rotating shaft 500 and the second rotating shaft 600.

[0078] The stirring device is provided with a stirring mechanism 300 and a dispersing mechanism 400. Through the cooperation between the stirring mechanism 300 and the dispersing mechanism 400, the stirring device has both stirring and dispersing functions, so that the slurry can be stirred more evenly and the quality of the slurry is improved.

[0079] In this embodiment, the top of the dispersion shaft 410 is transmission-connected with the driving mechanism 200, and the top of the dispersion shaft 410 can be transmission-connected with the driving mechanism 200 through the transmission mechanism. Thus, the stirring mechanism 300 and the dispersion mechanism 400 are simultaneously driven to rotate by the driving mechanism 200 such as a motor. For example, the output end of the driving motor can be connected to a transmission mechanism such as a gear, and the transmission mechanism such as a gear is respectively transmission-connected with the dispersion shaft 410 and the first rotating shaft 500 of the dispersion mechanism 400, and the first rotating shaft 500 is connected to the stirring mechanism 300, and then the dispersion mechanism 400 and the stirring mechanism 300 are simultaneously driven to rotate by the motor. Compared with the existing solution of using two driving mechanisms 200 to drive the dispersion mechanism 400 and the stirring mechanism 300 respectively, the present application has a simple structure, can reduce the setting of the driving motor, reduce the weight, and save costs.

[0080] The number of the above-mentioned dispersing mechanisms 400 can be multiple, that is, at least two, such as two, three or more dispersing mechanisms 400. In order to reduce costs while ensuring the dispersing effect, in this embodiment, two dispersing mechanisms 400 are provided, that is, two dispersing shafts 410 are provided, and each dispersing shaft 410 is provided with multiple dispersing components 420, and the two dispersing shafts 410 can be symmetrically arranged on both sides of the stirring mechanism 300. Of course, in other embodiments, more than two dispersing mechanisms 400 can also be provided, and the specific setting can be selected according to actual needs.

[0081] The above-mentioned multiple dispersion components 420 are arranged at intervals along the length direction of the dispersion axis 410. The specific number of the dispersion components 420 is not limited in this embodiment. The number of dispersion components 420 can be set according to the actual situation such as the length of the dispersion axis 410, such as 2 groups, 4 groups, 5 groups, 6 groups, etc. Optionally, the dispersion components 420 on at least two dispersion axes 410 are located at different heights, that is, the dispersion components 420 on at least two dispersion axes 410 can be arranged in a staggered manner. In this way, the slurry at different height positions can be dispersed, which can further improve the dispersion effect of the slurry. In addition, in other embodiments, the dispersion components 420 on at least two dispersion axes 410 can also be arranged in parallel.

[0082] Through the above arrangement, the slurry gathered between the stirring mechanism 300 and the dispersion can be dispersed, so that the stirring paddle can perform the stirring operation more effectively, thereby improving the stirring efficiency.

[0083] like Figure 1 or Figure 6 As shown, in some embodiments, the dispersion assembly 420 includes a dispersion wheel 421 and a dispersion disk 422 , the dispersion wheel 421 is disposed on the dispersion shaft 410 , and the dispersion disk 422 is disposed on the dispersion wheel 421 .

[0084] By setting the dispersion component 420 on the dispersion shaft 410 and setting the dispersion disk 422 on the dispersion shaft 410 through the dispersion wheel 421, the dispersion wheel 421 and the dispersion disk 422 on the dispersion shaft 410 will disperse the secondary flow generated during the stirring process during rotation, which can shorten the stirring time, improve the stirring efficiency, and improve the uniformity of the slurry.

[0085] In addition, by adopting the above structure, such as by setting the above stirring mechanism 300 and the dispersion mechanism 400, it is possible to avoid interference between the stirring paddle and the dispersion shaft 410 during the operation of the stirring device, so that the stirring operation can be carried out reliably.

[0086] like Figures 1 to 3As shown, in order to make the driving mechanism 200 respectively connected to the first rotating shaft 500 and the dispersion shaft 410, a transmission mechanism is also provided in the embodiment of the present application. In some embodiments, the stirring device further includes a first transmission mechanism 700 and a second transmission mechanism 800;

[0087] The first transmission mechanism 700 includes a first driving wheel 710 and a first driven wheel 720 meshing with each other; the first driving wheel 710 is in transmission connection with the first rotating shaft 500; the first driven wheel 720 is in transmission connection with the dispersion shaft 410;

[0088] The second transmission mechanism 800 includes a second driving wheel 810 and a second driven wheel 820 meshing with each other; the other end of the dispersion shaft 410 extends out of the mixing shell 100, and the second driven wheel 820 is transmission-connected to the dispersion shaft 410; the second driving wheel 810 is rotatably disposed on the second rotating shaft 600.

[0089] The above-mentioned first transmission mechanism 700 can be arranged above the first wall 110, the upper end of the first rotating shaft 500 extends out of the first wall 110 and is transmission-connected to the first driving wheel 710 located above the first wall 110, and the top end of the first rotating shaft 500 is connected to the output end of the driving motor; the top end of the dispersion shaft 410 extends out of the first wall 110 and is transmission-connected to the first driven wheel 720 located above the first wall 110, and the first driven wheel 720 and the first driving wheel 710 are meshed with each other.

[0090] The above-mentioned second transmission mechanism 800 can be arranged below the second wall 120, the lower end of the second rotating shaft 600 extends out of the second wall 120, and the second driving wheel 810 located below the second wall 120 can be rotatably arranged on the second rotating shaft 600; the lower end of the dispersion shaft 410 extends out of the second wall 120, and the second driven wheel 820 located below the second wall 120 can be rotatably arranged on the dispersion shaft 410, or the dispersion shaft 410 is transmission-connected to the second driven wheel 820, and the second driving wheel 810 and the second driven wheel 820 are meshed with each other.

[0091] It should be understood that the first wall 110 is provided with through holes for the first rotating shaft 500 and the dispersion shaft 410 to pass through respectively, and the second wall 120 is provided with through holes for the second rotating shaft 600 and the dispersion shaft 410 to pass through respectively. This embodiment does not limit the specific connection method between the first wall 110 and the first rotating shaft 500 and the dispersion shaft 410, and the specific connection method between the second wall 120 and the second rotating shaft 600 and the dispersion shaft 410, and will not be repeated here.

[0092] The driving motor is connected to the first rotating shaft 500 and the dispersion shaft 410 by gear transmission, which has a simple structure, low cost and easy maintenance.

[0093] When multiple dispersion mechanisms 400 are provided, the first transmission mechanism 700 includes multiple first driven wheels 720, and the second transmission mechanism 800 includes multiple second driven wheels 820. The number of the first driven wheels 720 and the second driven wheels 820 can be adapted to the number of the dispersion shafts 410. For example, when two dispersion mechanisms 400 are provided, two first driven wheels 720 can be provided around the first driving wheel 710, and the two first driven wheels 720 are respectively connected to the two dispersion shafts 410. The first driving wheel 710 can simultaneously engage with the two first driven wheels 720, so that the two first driven wheels 720 rotate in the same direction, thereby forming a shear force, which can fully mix the slurry and make it easy to disperse. Similarly, two second driven wheels 820 can be provided around the second driving wheel 810, and the two second driven wheels 820 are respectively connected to the two dispersion shafts 410. The second driving wheel 810 can simultaneously engage with the two second driven wheels 820 to improve the stirring and dispersing effect, or ensure the supporting effect, so that the overall structure is more stable and reliable.

[0103] In some embodiments, the stirring mechanism 300 further includes a third driving wheel 340, a plurality of third driven wheels 350, a fourth driving wheel 360, and a plurality of fourth driven wheels 370;

[0104] The third driving wheel 340 is attached to the lower side of the first rotating disk 310 and is in transmission connection with the first rotating shaft 500.

[0105] The fourth driving wheel 360 is attached to the top of the second rotating disk 320 and is transmission-connected to the second rotating shaft 600 . The plurality of fourth driven wheels 370 are rotationally connected to the other end of the stirring paddle 330 , and are located around the fourth driving wheel 360 and meshed with the fourth driving wheel 360 .

[0106] In the above stirring mechanism 300, a stirring paddle 330, a third driving wheel 340, a plurality of third driven wheels 350, a fourth driving wheel 360 and a plurality of fourth driven wheels 370 are arranged between the first rotating disk 310 and the second rotating disk 320. The third driving wheel 340 is connected to the lower end of the first rotating disk 310, and a plurality of third driven wheels 350, such as two or more, are meshed around the third driving wheel 340 at the same time. The fourth driving wheel 360 is connected to the upper end of the second rotating disk 320, and a plurality of fourth driven wheels 370, such as two or more, are meshed around the fourth driving wheel 360 at the same time. The upper and lower ends of the stirring paddle 330 are respectively connected to the first rotating disk 310 and the second rotating disk 320, and the stirring paddle 330 is connected to the third driven wheel 350 and the fourth driven wheel 370. The first rotating shaft 500 is connected to the first rotating disk 310 and the third driving wheel 340, and the second rotating shaft 600 is connected to the second rotating disk 320 and the fourth driving wheel 360. Therefore, based on the setting of the above stirring mechanism 300, the connection method or transmission connection is reliable, which can play a certain supporting role, so that the stirring paddle 330 can perform stirring operations more effectively, which is more conducive to the mixing of the slurry, can make the slurry fully mixed, and can reduce or avoid the problem of the stirring paddle 330 deforming and scraping the side wall.

[0107] like Figure 1 or Figure 5 As shown, in order to improve the stirring, extruding and dispersing effect, the stirring mechanism 300 of this embodiment is also provided with an extrusion assembly 380 capable of producing an extrusion effect on the slurry. In some embodiments, the stirring mechanism 300 further includes an extrusion assembly 380, which is disposed in the stirring housing 100 and connected to the second rotating shaft 600.

[0108] The extrusion assembly 380 may be disposed below the stirring mechanism 300 , and the top end of the second rotating shaft 600 may extend into the stirring housing 100 and be connected to the extrusion assembly 380 .

[0109] In some embodiments, the extrusion assembly 380 includes a cone member 381, the large end of the cone member 381 is connected to the second rotating shaft 600, and the small end of the cone member 381 is arranged toward the first rotating shaft 500; the conical surface of the cone member 381 is provided with a material guide channel 3811; further, the extrusion assembly 380 may also include a screw 382, ​​the bottom end, i.e., the large end, of the cone member 381 can be connected to the screw 382, ​​the cone member 381 is connected to the second rotating shaft 600 through the screw 382, ​​and the screw 382 can be connected to the fourth driving wheel 360 and the second turntable 320 through the second rotating shaft 600.

[0110] In some embodiments, the material guide channel 3811 includes a threaded structure. Of course, in other embodiments, other structural forms that can be used for guiding materials can also be used. The material guide channel 3811 with a threaded structure has a simple structure and is easy to process and manufacture. In addition, a certain shear force can be generated through the threaded structure to gradually soften the material, further fully mix the material, and improve the stirring and dispersing effect.

[0111] Therefore, by setting the extrusion component 380 and utilizing the material guide channel 3811 and the screw 382 of the cone 381, the slurry at the bottom can be transported to the conical top of the cone 381, and cooperate with the stirring paddle 330 and the dispersion mechanism 400 to generate a strong shear force. In addition, the rotation of the screw 382 causes friction of the material during the movement, allowing the material to gradually soften and further fully and evenly mix, and then be extruded from the tip of the cone 381, further improving the dispersion and stirring effect.

[0112] like Figure 1As shown, in some embodiments, the side wall of the stirring shell 100 is provided with a feed port 130 and a discharge port 140; the feed port 130 is adjacent to the first wall 110, and the discharge port 140 is adjacent to the second wall 120; the feed port 130 and the discharge port 140 are respectively located on opposite sides of the stirring mechanism 300. For example, the feed port 130 can be arranged at the upper end of the side wall of the stirring shell 100 and adjacent to the first wall 110, and the discharge port 140 can be arranged at the lower end of the side wall of the stirring shell 100 and adjacent to the second wall 120, and the feed port 130 and the discharge port 140 can be located in different directions. Through the setting of the feed port 130, it can be used to input the raw materials to be stirred into the stirring shell 100; through the setting of the discharge port 140, the slurry obtained after stirring can be output from the stirring shell 100.

[0113] The working principle of the stirring device in the embodiment of the present application is as follows:

[0114] The material to be stirred is filled into the stirring shell 100 through the feed port 130; the first rotating shaft 500 is driven to rotate by the driving mechanism 200 such as a motor, and the first driving wheel 710 in the first transmission mechanism 700, the first rotating disk 310 and the third driving wheel 340 in the stirring mechanism 300 are connected in series through the first rotating shaft 500 to achieve a linkage effect. The rotation of the first rotating disk 310 carries the self-rotation and revolution of the third driven wheel 350, such as self-rotation with its own bearing, revolution with the bearing of the first rotating disk 310 or revolution of the third driving wheel 340; the upper and lower ends of the stirring paddle 330 are connected in series with the first rotating disk 310 and the second rotating disk 320, and the third driven wheel 350 and the fourth driven wheel 370 in the stirring mechanism 300 are connected through the stirring paddle 330. Similarly, the fourth driven wheel 370 rotates with its own bearing, and revolves with the bearing of the second rotating disk 320 or the fourth driving wheel 360. The screw 382 of the extrusion assembly 380 can be arranged inside the fourth driving wheel 360 through the second rotating shaft 600. The screw 382 is rotated by the synergistic action of the driven second turntable 320 and the fourth driving wheel 360, and the cone member 381 is driven to rotate, and then the slurry at the bottom can be transported to the conical top of the cone member 381 through the material guide channel 3811 of the cone member 381, and cooperate with the stirring paddle 330 and the dispersion mechanism 400 to generate a strong shear force. In addition, the rotation of the screw 382 causes friction of the material during the movement, so that the material gradually softens and is further fully and evenly mixed, and then extruded from the tip of the cone member 381, further improving the dispersion and stirring effect. At the same time, the first driving wheel 710 and the first driven wheel 720 in the first transmission mechanism 700 are meshed with each other, and the first driven wheel 720 is connected to the dispersion shaft 410. The second driving wheel 810 and the second driven wheel 820 in the second transmission mechanism 800 are meshed with each other, and the second driven wheel 820 is connected to the dispersion shaft 410, thereby driving the dispersion shaft 410 to rotate, and then driving the dispersion assembly 420 disposed on the dispersion shaft 410 to rotate, thereby improving the dispersion effect. The slurry obtained after stirring can be output from the stirring shell 100 through the discharge port 140.

[0115] Thus, the embodiment of the present application adopts an upper and lower integrated upright bearing structure, the first driven wheel 720 and the second driven wheel 820 are connected by the dispersion shaft 410, and the first driving wheel 710 and the second driving wheel 810 are connected in series by the stirring paddle 330, which can effectively solve the splitting problem caused by the wear of the current stirring bearing and solve the problem of the current stirring paddle deforming and scraping the wall of the stirring tank; and the structural design of the double dispersion shaft 410 bearing has a good dispersion effect on the slurry, and an extrusion assembly 380 is also provided. Through the setting of the conical screw extrusion structure, the slurry is squeezed by the rotation of the screw 382, ​​which can play the role of transmission and extrusion. The combined effect of the stirring paddle 330 and the dispersion mechanism 400 can improve the stirring and dispersion effect, and improve the production efficiency and quality of the slurry.
