During the process of battery manufacturing, a homogenizer is required. The quality of battery slurry depends on two factors: one is the homogenization equipment, and the other is the homogenization process.

[0003] For example, the utility model with the application number CN202322307252.6 discloses a homogenization device for battery manufacturing. Similar homogenization devices for battery manufacturing as described in the above application still have the following deficiencies: during the stirring and homogenization process of battery raw materials, although continuous stirring can be carried out, only using a stirring structure is not conducive to completely dispersing the slurry, and thus not conducive to the homogenization efficiency.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a homogenizer for battery manufacturing that reduces discharge residue is proposed. Content of the Utility Model

The upper scraping plate 502 is fixed on the outer side of the homogenizing blade 501, and the lower scraping plate 504 is connected to the outer side of the bottom of the stirring shaft 3 through the connecting rod 503, and the outer side surface of the lower scraping plate 504 is attached to the inner side surface of the discharge hopper 10; the driving motor 8 facilitates driving the rotation of the stirring shaft 3 and the mixing and homogenizing component 5, so that the homogenizing blade 501 can stir the slurry inside the outer shell 1, and at the same time, the upper scraping plate 502, the connecting rod 503, and the lower scraping plate 504 can rotate synchronously to scrape the inner walls of the outer shell 1 and the discharge hopper 10 on one side, so as to reduce discharge residue subsequently.

[0021] As Figures 1-3As shown in the figure, a bubble removal component 9 is installed below the interior of the outer shell 1, and the bubble removal component 9 includes a filter screen 901, a horizontal plate 902, and steel brush needles 903. The filter screen 901 is bolted to the inner wall of the outer shell 1. Two sets of upper and lower horizontal plates 902 are fixedly installed outside the lower part of the stirring shaft 3, and a plurality of steel brush needles 903 are evenly fixed on one side of the horizontal plate 902 close to the filter screen 901. The two sets of upper and lower horizontal plates 902 and the steel brush needles 903 are symmetrically arranged with respect to the horizontal center line of the filter screen 901, and one end of the steel brush needle 903 is in contact with the outer side of the filter screen 901. The filter screen 901 is beneficial for bubble removal, enabling bubbles to be captured by the filter screen 901. At the same time, the rotation of the stirring shaft 3 can drive the rotation of the horizontal plate 902 and the steel brush needles 903, so that the two sets of upper and lower steel brush needles 903 can pierce and disperse the bubbles at the filter screen 901 and dissipate the bubbles, achieving the purpose of removing bubbles.

[0022] As Figures 1-2 shown in the figure, a stirring and shearing component 2 is installed above the interior of the outer shell 1, and the stirring and shearing component 2 includes a shearing cylinder 201, a mounting plate 203, a main blade 204, and shearing blades 205. The inner wall of the shearing cylinder 201 is bolted to the mounting plate 203, and a main blade 204 is fixed inside the mounting plate 203. Shearing blades 205 are fixed on both sides of the main blade 204, and the shearing blades 205 are distributed in a dendritic shape. The stirring and shearing component 2 further includes a fixing block 202, a through groove 206, and a hollowed-out net 207. One side of the shearing cylinder 201 is fixedly connected to the outer shell 1 through the fixing block 202, and the vertical center lines of the shearing cylinder 201 and the outer shell 1 coincide. A through groove 206 is formed in the outer wall of the shearing cylinder 201, and a hollowed-out net 207 is fixed inside the through groove 206. By means of the stirring shaft 3, it is convenient to drive the rotation of the stirring blades 4, so that the stirring blades 4 can drive the slurry to repeatedly impact the inner wall of the shearing cylinder 201. The cutting edges of several groups of main blades 204 and shearing blades 205 inside the shearing cylinder 201 are staggered, which can generate different shearing forces, forming a kind of shearing mechanism. Thus, the slurry can be dispersed and sheared during the process of high-speed rotation and impact of the slurry, making the slurry mixing more uniform, improving the homogenization efficiency, and the sheared slurry can enter the interior of the outer shell 1 through the hollowed-out net 207 inside the through groove 206.

[0023] In summary, as Figures 1-3As shown in the figure, when the homogenizer for battery manufacturing that reduces discharge residue is in use, first, the slurry for battery manufacturing can be fed into the interior of the shear cylinder 201 of the outer housing 1 through the feed pipe 7. Then, the driving motor 8 drives the rotation of the stirring shaft 3 and the stirring blades 4, so that the stirring blades 4 can drive the slurry to reciprocally impact the inner wall of the shear cylinder 201. The cutting edges of several groups of main blades 204 and shear blades 205 on the inner side of the shear cylinder 201 are staggered to generate different shearing forces, forming a kind of shearing mechanism. Thus, the slurry can be dispersed and sheared during the process of high-speed rotation and impact of the slurry, making the slurry mixing more uniform and improving the homogenization efficiency. Then, the sheared slurry can enter the interior of the outer housing 1 through the hollow net 207 inside the through slot 206. At this time, the stirring shaft 3 can drive the rotation of the mixing and homogenizing assembly 5, so that the homogenizing blades 501 can stir and homogenize the slurry inside the outer housing 1. Then, at the same time, the upper scraping plate 502, the connecting rod 503, and the lower scraping plate 504 can rotate synchronously to scrape the inner wall side of the outer housing 1 and the material discharge hopper 10, so as to reduce the discharge residue in the subsequent process. Then, the bubbles in the slurry during discharging will be captured by the filter screen 901. At this time, the rotation of the stirring shaft 3 can drive the rotation of the cross plate 902 and the steel brush needles 903, so that the upper and lower groups of steel brush needles 903 can pierce and disperse the bubbles at the filter screen 901 and make the bubbles dissipate, achieving the purpose of removing bubbles. Finally, the slurry is discharged through the discharge port 11, and thus the use process of the homogenizer for battery manufacturing that reduces discharge residue is completed.
