These drawings and detailed description are not intended to limit the scope of the concept of the present application in any way, but to explain the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0024] In order to make the purposes, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily mean the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0027] The existing homogenizer has two dispersion discs fixed on one shaft, and the material needs to cover the two dispersion discs, and the slurry around the dispersion discs can be uniformly dispersed. However, in the actual feeding process, according to the needs of battery production, the feeding amount is not fixed, so the position of the dispersion disc needs to be adjusted according to the feeding amount each time to ensure that the slurry covers the two dispersion discs and realizes uniform dispersion of the slurry. Moreover, the two dispersion discs cannot realize multi-liquid surface layer dispersion, and the dispersion force can only be around the two dispersion discs, and a long homogenization time is required to realize uniformity and stability of the slurry. In the semi-dry homogenization process, the slurry has a climbing rod phenomenon, and often needs to adjust the appropriate solid content to make the material climb the rod and then fall and be hit by the dispersion disc to realize dispersion, which has poor dispersion effect.

[0028] Please refer to Figure 1 , Figure 1 is a partial structure schematic diagram of a lithium battery homogenization and dispersion device provided by the embodiments of the present application. The lithium battery homogenization and dispersion device 000 can include a driving component 100, a dispersion rod 200, a spiral dispersion disc 300 and a first dispersion disc 400. Here, the driving component 100 can be a planetary box.

[0029] The dispersion rod 200 in the lithium battery homogenate dispersion device 000 can be located at one side of the driving component 100 and can be in transmission connection with the driving component 100.

[0030] The spiral dispersion disc 300 in the lithium battery homogenate dispersion device 000 can be fixedly connected with the side surface of the dispersion rod 200, and the spiral dispersion disc 300 can extend spirally along the length direction of the dispersion rod 200. The two sides of the edge portion of the spiral dispersion disc 300 can respectively have a plurality of first dispersion shear blades 301 and a plurality of second dispersion shear blades 302. Here, the two sides of the edge portion of the spiral dispersion disc 300 refer to the top surface and the bottom surface of the edge portion of the spiral dispersion disc 300.

[0031] The first dispersion disc 400 in the lithium battery homogenate dispersion device 000 can be located at the side of the spiral dispersion disc 300 away from the driving component 100 and can be fixedly connected with the side surface of the dispersion rod 200.

[0032] The direction in which the driving component 100 drives the dispersion rod 200 to rotate can correspond to the rotation direction of the spiral dispersion disc 300, so that the slurry moves towards the first dispersion disc 400. For example, as shown in Figure 1 The rotation direction of the spiral dispersion disc 300 can be right-handed, and the driving component 100 can drive the dispersion rod 200 to rotate in the clockwise direction.

[0033] In the embodiments of the present application, by integrating the spiral dispersion disc 300 in the lithium battery homogenate dispersion device, the spiral dispersion disc 300 can realize dispersion of the multiple liquid surface layers of the slurry, without the need to adjust the position of other dispersion discs (for example, the first dispersion disc) according to the size of the feeding amount. By controlling the rotation direction of the dispersion rod 200 by the driving component 100, the slurry can be moved from the upper liquid surface to the direction of the first dispersion disc 400, the climbing bad phenomenon of the semi-dry process can be reduced, and the slurry dispersion can be carried out at the same time in the process of slurry movement, and the prepared slurry has the same viscosity within 24h. In addition, the lithium battery homogenate dispersion device 000 integrated with the spiral dispersion disc 300 has simple structure, can not only realize uniform dispersion of the slurry, but also can shorten the homogenate process time, improve the production efficiency, and is suitable for large-scale production.

[0034] In summary, the embodiment of the present application provides a lithium battery homogenate dispersion device, which can include a driving component, a dispersion rod, a spiral dispersion disc and a first dispersion disc. By integrating the spiral dispersion disc in the lithium battery homogenate dispersion device, the spiral dispersion disc can realize the dispersion of multiple liquid surface layers of the slurry, without the need to adjust the position of the dispersion disc according to the size of the feeding amount. By controlling the rotation direction of the dispersion rod through the driving component, the slurry can be moved from the upper liquid surface to the direction of the first dispersion disc, reducing the poor phenomenon of climbing in the semi-dry process, and simultaneously dispersing during the movement of the slurry. The prepared slurry has the same viscosity within 24 hours. In addition, the lithium battery homogenate dispersion device integrated with the spiral dispersion disc has a simple structure, which not only can realize the uniform dispersion of the slurry, but also can shorten the homogenate process time, improve the production efficiency, and is suitable for large-scale production.

[0035] Optionally, as shown in Figure 1 , the plurality of first dispersion shear blades 301 and the plurality of second dispersion shear blades 302 fixed on the edge portion of the spiral dispersion disc 300 are staggered. In this way, the dispersion effect of the spiral dispersion disc 300 on the slurry can be further improved. That is, one second dispersion shear blade 302 can be distributed between every two adjacent first dispersion shear blades 301, and one first dispersion shear blade 301 can be distributed between every two adjacent second dispersion shear blades 302.

[0036] In the embodiment of the present application, please refer to Figure 2 , Figure 2 is another partial structure schematic diagram of the lithium battery homogenate dispersion device provided by the embodiment of the present application. The target dispersion shear blade can have two first side edges Z1 arranged in parallel and two second side edges Z2 arranged in parallel, and one first side edge Z1 can be fixedly connected with the edge portion of the spiral dispersion disc 300. Here, the extension direction of the area where the edge portion of the spiral dispersion disc 300 contacts with one first side edge Z1 of the target dispersion shear blade can be arranged in parallel with the other first side edge Z1 of the target dispersion shear blade.

[0037] Among them, the target dispersion shear blade can be any one of the first dispersion shear blade 301 and the second dispersion shear blade 302. That is, the first dispersion shear blade 301 can be the target dispersion shear blade, or the second dispersion shear blade 302 can be the target dispersion shear blade, or both the first dispersion shear blade 301 and the second dispersion shear blade 302 can be the target dispersion shear blade.

[0038] In the present application, as Figure 2As shown, the length of the first dispersion shear blade 301 and the second dispersion shear blade 302 can be the same, and the width of the first dispersion shear blade 301 and the second dispersion shear blade 302 can also be the same. Here, the shape of the first dispersion shear blade and the second dispersion shear blade can be the same.

[0039] Optionally, as Figure 2 As shown, the lithium battery homogenate dispersion device 000 can further include a second dispersion disc 500, which can be located on the side of the spiral dispersion disc 300 close to the driving component 100 and fixedly connected with the side surface of the dispersion rod 200. In this way, the spiral dispersion disc 300, the first dispersion disc 400 and the second dispersion disc 500 can be driven to rotate synchronously in the process that the driving component 100 drives the dispersion rod 200 to rotate, so as to uniformly disperse the slurry.

[0040] In the embodiment of the present application, as Figure 2 As shown, the lithium battery homogenate dispersion device 000 can further include a stirring paddle 600 in transmission connection with one side of the driving component 100, which can be arranged adjacent to the dispersion rod 200. In this way, the slurry in the lower barrel can be stirred by the stirring paddle 600. It should be noted that the lower barrel in the lithium battery homogenate dispersion device 000 is described in subsequent embodiments.

[0041] Optionally, please refer to Figure 3 , Figure 3 is another partial structure schematic diagram of the lithium battery homogenate dispersion device provided in the embodiment of the present application. The lithium battery homogenate dispersion device 000 can further include a lower barrel 700 arranged opposite to the driving component 100, which can be used to load the slurry. Here, the dispersion rod 200, the first dispersion disc 400, the spiral dispersion disc 300, the second dispersion disc 500 and the stirring paddle 600 can all be located on the side of the driving component 100 facing the lower barrel 700. Here, the driving component 100 can drive the first dispersion disc and the spiral dispersion disc to revolve around the central axis of the lower barrel 700, and can drive the first dispersion disc 400 and the spiral dispersion disc 300 to rotate by the two dispersion rods 200.

[0042] For example, the lithium battery homogenate dispersion device 000 can further include an upper barrel (not shown in the figure) arranged opposite to the lower barrel 700, and the driving component 100 can be installed in the upper barrel, and the upper barrel can be buckled with the lower barrel in the process of slurry dispersion.

[0043] In summary, the embodiment of the present application provides a lithium battery homogenate dispersion device, which can include a driving component, a dispersion rod, a spiral dispersion disc and a first dispersion disc. By integrating the spiral dispersion disc in the lithium battery homogenate dispersion device, the spiral dispersion disc can realize the dispersion of multiple liquid surface layers of the slurry, without the need to adjust the position of the dispersion disc according to the size of the feeding amount. By controlling the rotation direction of the dispersion rod through the driving component, the slurry can be moved from the upper liquid surface to the direction of the first dispersion disc, reducing the poor phenomenon of climbing in the semi-dry process, and simultaneously dispersing the slurry in the process of moving the slurry, so that the prepared slurry has the same viscosity within 24 hours. In addition, the lithium battery homogenate dispersion device integrated with the spiral dispersion disc has a simple structure, which can not only realize the uniform dispersion of the slurry, but also shorten the homogenate process time, improve the production efficiency, and is suitable for large-scale production.
