Description

[0002] Lithium ion battery has the advantages of cyclic continuous utilization, less pollution, long service life, and in recent years, it develops rapidly, is widely used in consumer electronics, electric vehicles, energy storage and other fields, and is growing at a high speed every year.

[0003] Pulping is the first process of lithium ion battery manufacturing, and the quality of slurry greatly affects the battery quality, which is the most critical process in battery manufacturing. The traditional pulping process mainly adopts double planetary stirring, and the slurry is dispersed by the paddle for a long time. The process efficiency is low, and it is difficult to meet the process and battery performance requirements. Emerging pulping process adopts continuous dispersion process; the main principle of continuous dispersion process is that the high-speed rotation of the rotating impeller in the dispersion cavity can disperse the inhaled powder and solvent through strong shearing force and strong turbulent flow formed by the solvent. Since the dispersion cavity has small gap and adopts circulating conveying mode, the slurry can be dispersed quickly and efficiently, effectively solving the problem of low efficiency of traditional pulping process. However, the continuous dispersion process is short in continuous dispersion time and low in dispersion frequency, which can easily cause the shearing frequency of PVDF (Chinese name: polyvinylidene fluoride) to be low, the viscosity of the slurry to be high, and thus the BOM cost (i.e. the cost of the production and manufacturing link) to increase, and the coating manufacturing cost to be high.

[0052] The stirring device 200 is provided with a first feeding port 211, a second feeding port 212 and a discharging port 213; optionally, the stirring device 200 includes a dispersion tank 210; the first feeding port 211, the second feeding port 212 and the discharging port 213 are respectively arranged on the dispersion tank 210, and the first feeding port 211 is used for supplying the powder into the dispersion tank 210.

[0055] The pipeline dispersion device 100 is installed in at least one of the first pipeline 510 and the second pipeline 520; that is, the pipeline dispersion device 100 can be installed in the first pipeline 510, can be installed in the second pipeline 520, and can also be installed in both the first pipeline 510 and the second pipeline 520. The specific installation position and the number of the pipeline dispersion device 100 can be determined according to the installation position, the structural relationship, the conveying capacity and the performance of the slurry of the continuous dispersion system and other factors. Optionally, the number of the pipeline dispersion device 100 is 1, 2, 4, 5 or other numbers.

[0056] The pipeline dispersion device 100 comprises a disperser 150 for dispersing the slurry. The disperser 150 disperses the slurry, thereby increasing the shearing times of the slurry and the dispersion performance of the slurry, and effectively reducing the viscosity of the slurry.

[0057] The continuous dispersion system in the embodiment comprises the pipeline dispersion device 100, the stirring device 200, the storage transfer device 300, the first pipeline 510 and the second pipeline 520. The first pipeline 510 is connected to the discharge port 213 of the stirring device 200 and the circulating feed port 311 of the storage transfer device 300, and the second pipeline 520 is connected to the circulating discharge port 312 of the storage transfer device 300 and the second feed port 212 of the stirring device 200. The pipeline dispersion device 100 is installed in at least one of the first pipeline 510 and the second pipeline 520, so that the disperser 150 of the pipeline dispersion device 100 disperses the slurry, thereby effectively increasing the shearing times of the slurry and the dispersion performance of the slurry, and effectively reducing the viscosity of the slurry.

[0058] Referring to FIGS. 1, 2, 3, 4, 5 and 6, Figure 3 and Figure 4 In an optional solution of the embodiment, the pipeline dispersion device 100 further comprises a shell 110, a support 120, a rotating rod 130 and a blade 140. The shell 110 is provided with the support 120 supporting and connecting the rotating rod 130. The rotating rod 130 is located in the shell 110. The rotating rod 130 is stably rotated relative to the shell 110 through the support 120 supporting and connecting the rotating rod 130.

[0059] The blade 140 and the disperser 150 are sequentially connected with the rotating rod 130 along the flow direction of the slurry. The blade 140 and the disperser 150 are both located in the shell 110. Optionally, the blade 140 is fixedly connected with the rotating rod 130, for example, the blade 140 is fixedly connected with the rotating rod 130 by welding, screw connection, adhesion or the like. Optionally, the disperser 150 is fixedly connected with the rotating rod 130, for example, the disperser 150 is fixedly connected with the rotating rod 130 by welding, screw connection, adhesion or the like.

[0060] The rotating rod 130 is configured to be rotatable about the central axis of the rotating rod 130 in the shell 110, and the blade 140 and the disperser 150 are both rotatable with the rotating rod 130. The blade 140 and the disperser 150 are both rotatable with the rotating rod 130, which can be driven to rotate by an external force, thereby rotating the blade 140 and the disperser 150. Alternatively, the blade 140 and the disperser 150 can be driven to rotate by the flow impact force of the slurry, thereby rotating the rotating rod 130. For example, the flow impact force of the slurry is utilized to drive the blade 140 to rotate to disperse the slurry during the circulation and dispersion of the slurry, thereby driving the rotating rod 130 to rotate, and further driving the disperser 150 connected with the rotating rod 130 to rotate, so as to shear and disperse the slurry again, increase the shearing times of the slurry, and achieve the effect of reducing the viscosity of the slurry.

[0061] In the embodiment, the rotating rod 130 can be fixedly connected with the support 120, and when the rotating rod 130 rotates around its central axis, the support 120 rotates synchronously. Alternatively, the rotating rod 130 can be rotatably connected with the support 120, and the support 120 is fixedly connected with the shell 110, and when the rotating rod 130 rotates around its central axis, neither the support 120 nor the shell 110 rotates. As shown in Figure 3 In an alternative embodiment of the present application, the pipeline dispersion device 100 further comprises a bearing 160, and the opposite ends of the rotating rod 130 are respectively connected with a support 120, and the bearing 160 is connected between the rotating rod 130 and the support 120. By arranging the bearing 160 between the rotating rod 130 and the support 120, the rotating resistance of the rotating rod 130 is reduced to a certain extent, which is conducive to the rotation of the blade 140 and the disperser 150.

[0062] In the embodiment, the support 120 can also be arranged in the shell 110 to support the rotating rod 130.

By arranging multiple dispersers 150, the shearing times of the slurry are increased to a certain extent, and the dispersion performance of the slurry is improved to a certain extent, which can effectively reduce the viscosity of the slurry.

[0064] Alternatively, the number of the blades 140 is one or multiple. Alternatively, the shape of the blade 140 is spiral or other shapes.

[0065] As shown in Figure 2 and Figure 4 In an alternative embodiment of the present application, the pipeline dispersion device further comprises a driver 170, and the fixed end of the driver 170 is connected to the outside of the shell 110, and the driving end of the driver 170 is connected with the rotating rod 130. By connecting the rotating rod 130 with the driver 170, the rotating speed of the blade 140 and the disperser 150 can be increased, thereby effectively increasing the shearing times of the slurry, effectively improving the dispersion performance of the slurry, and effectively reducing the viscosity of the slurry.

[0066] As shown in Figure 5 and Figure 6As shown, in an optional embodiment of the present embodiment, the disperser 150 comprises a base 151 and a sidewall 152 peripherally arranged around the base 151. A plurality of through holes 153 are arranged on the base 151 and / or the sidewall 152, that is, a plurality of through holes 153 are arranged on the base 151, or a plurality of through holes 153 are arranged on the sidewall 152, or a plurality of through holes 153 are arranged on both the base 151 and the sidewall 152. Through the through holes 153, the dispersing performance of the disperser 150 on the slurry can be effectively improved.

[0067] In an optional embodiment of the present embodiment, the distance between the central axis of the rotating rod 130 and the central axis of the shell 110 is greater than or equal to 0 and less than or equal to 15 mm; alternatively, the central axis of the rotating rod 130 coincides with the central axis of the shell 110. For example, the distance between the central axis of the rotating rod 130 and the central axis of the shell 110 is 0.5 mm, 2 mm, 5 mm, 13 mm, 15 mm, or other values.

[0068] In an optional embodiment of the present embodiment, the diameter and length of the shell 110 can be adjusted according to the diameter and size of the connected pipeline, for example, the diameter of the shell 110 ranges from 50 mm to 200 mm, and the length of the shell 110 ranges from 0.2 m to 5 m along the central axis of the shell 110.

[0069] In an optional embodiment of the present embodiment, the disperser 150 is arranged spaced apart from the inner wall of the shell 110 to prevent the shell 110 from affecting the rotation of the disperser 150. Alternatively, the gap between the disperser 150 and the inner wall of the shell 110 ranges from 0.5 mm to 30 mm, for example, the gap between the disperser 150 and the inner wall of the shell 110 is 0.5 mm, 1 mm, 8 mm, 20 mm, 30 mm, or other values. In the present embodiment, the specific gap between the disperser 150 and the inner wall of the shell 110 can be adjusted according to factors such as the viscosity and flowability of the slurry.

Through the conveying drive device 400, the flow rate of the slurry in the second pipeline 520 can be increased, which can effectively increase the number of shearing operations of the pipeline dispersion device 100 installed in the second pipeline 520 on the slurry; specifically, when the conveying drive device 400 conveys, the impact force of the slurry drives the blades 140 in the pipeline dispersion device 100 to make the rotating rod 130 rotate at high speed, and the rotating rod 130 drives the disperser 150 to shear and disperse the slurry at high speed; during the continuous dispersion system's cyclic dispersion, the pipeline dispersion device 100 in the second pipeline 520 continuously shears the slurry, thereby achieving the purpose of improving the slurry dispersion performance, reducing the slurry viscosity, and increasing the solid content.
