[0002] The high-speed, high-shear mixer for lithium battery powder is a device used to prepare positive and negative electrode materials for batteries. It is mainly used to mix, homogenize, and disperse various components in battery materials. This device typically uses high-speed rotating blades or cutters to mix various powders, particles, or liquids together through high-speed rotation and high shear force.
[0003] According to the utility model patent application CN222219220U, a high-speed, high-shear mixing device for lithium battery powder is disclosed. Although this device greatly improves the shearing efficiency, it has certain shearing mixing dead zones, which prevents the powder from being evenly dispersed during the mixing process. This results in excessively high powder concentration in some areas, causing the lithium battery powder to agglomerate and affecting the uniformity of the material and the quality of the final product. To address these issues, we provide a continuous high-speed, high-shear mixer. Utility Model Content

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0019] This embodiment provides a continuous high-speed high-shear mixer. The device is used to avoid the agglomeration of lithium battery powder during the shearing and mixing process by setting up a frame 1 and a shearing and mixing mechanism 2.
[0020] Please refer to Figure 1 and Figure 4 A continuous high-speed high-shear mixer includes a frame 1, with a shearing and mixing mechanism 2 inside the frame 1. The shearing and mixing mechanism 2 includes a vessel body 201, the bottom of which is fixedly connected to the inner bottom wall of the frame 1. A conveying box 213 and a storage tank 214 are fixedly installed on the upper surface of the frame 1. The bottom end of the storage tank 214 extends into the interior of the conveying box 213. A spiral conveying rod 215 is rotatably connected inside the conveying box 213. A rotating motor 216 is fixedly installed on the left side of the conveying box 213. The output end of the rotating motor 216 is fixedly connected to the left end of the spiral conveying rod 215. A connecting pipe 217 is fixedly connected to the bottom surface of the conveying box 213, and the bottom end of the connecting pipe 217 extends into the interior of the vessel body 201. The operator uses the power provided by the rotating motor 216 to drive the spiral conveying rod 215 to rotate, thereby continuously adding lithium battery powder from the storage tank 214 into the vessel body 201 without the need for manual addition by the operator.
[0021] Please refer to Figure 1 An air pump 202 and a connecting box 203 are fixedly installed on the upper surface of the vessel body 201. The air outlet of the air pump 202 extends into the interior of the connecting box 203. Two connecting ears 211 are fixedly installed on the front and back of the frame 1. An expansion bolt 212 is provided inside each connecting ear 211. The bottom end of each expansion bolt 212 extends into the bottom of the connecting ear 211. The expansion bolt 212 and the connecting ear 211 are used to fix the frame 1 to the ground, thereby preventing the frame 1 from moving on its own and ensuring the stability of the frame 1.
[0022] Please refer to Figure 1 and Figure 2 The connecting box 203 has several drying plates 204 snapped into its interior. The upper surface of the connecting box 203 is fixedly connected to a conveying pipe 205. The drying plates 204 are made of silica gel desiccant, which can absorb moisture in the air. The upper surface of the storage tank 214 is fixedly connected to a feed pipe 218. The outer surface of the feed pipe 218 is threadedly connected to a box cover 219. The installation of the feed pipe 218 and the box cover 219 allows workers to add lithium battery powder that needs to be sheared and mixed into the storage tank 214.
[0023] Please refer to Figure 2 and Figure 3 A stirring rack 206 is rotatably connected inside the vessel body 201. A first filter screen 207, made of fiberglass, is fixedly installed on the inner wall of the stirring rack 206 to prevent lithium battery powder from entering the interior of the stirring rack 206. A shearing rack 220 is rotatably connected inside the vessel body 201. A cylinder 221 is fixedly installed on the upper surface of the shearing rack 220. A first conical wheel 222 is fixedly installed on the upper surface of the cylinder 221. A second conical wheel 223 is fixedly installed on the outer surface of the stirring rack 206. A rotary motor 224 is fixedly installed on the upper surface of the vessel body 201. The output of the rotary motor 224... A third conical wheel 225 is fixedly installed at one end. The outer surface of the third conical wheel 225 meshes with the outer surfaces of the first conical wheel 222 and the second conical wheel 223 respectively. The stirring frame 206 passes through the shearing frame 220, the cylinder 221 and the first conical wheel 222, and rotates in contact with all three. The power provided by the rotary motor 224, in conjunction with the third conical wheel 225, drives the first conical wheel 222 and the second conical wheel 223 to rotate in different directions, thereby causing the shearing frame 220 and the stirring frame 206 to rotate in opposite directions, thus achieving the function of shearing and mixing the lithium battery powder.
[0024] Please refer to Figures 1-3The outer surface of the stirring rack 206 is provided with several air outlets 208. The top of the stirring rack 206 extends through to the outside of the vessel body 201 and is rotatably connected to the end of the conveying pipe 205 away from the connecting box 203. The bottom surface of the vessel body 201 is fixedly connected to the discharge pipe 226, and the outer surface of the discharge pipe 226 is fixedly connected to the solenoid valve 227. The installation of the discharge pipe 226 and the solenoid valve 227 serves to discharge the sheared and mixed lithium battery powder from the vessel body 201.
[0025] Please refer to Figure 2 A second filter screen 209 is fixedly installed on the upper surface of the vessel body 201. The second filter screen 209 is made of glass fiber to prevent lithium battery powder from entering the outside. A vibration motor 210 is fixedly installed on the upper surface of the vessel body 201. A water inlet pipe 228 is fixedly connected to the upper surface of the vessel body 201. A valve 229 is fixedly connected to the outer surface of the water inlet pipe 228. The installation of the water inlet pipe 228 and the valve 229 allows workers to add water to the inside of the vessel body 201, thus facilitating the cleaning of the inside of the vessel body 201.
[0026] Working Principle: During operation, the rotary motor 216 is activated using an external remote control. The power provided by the rotary motor 216 drives the spiral conveyor 215 to rotate, thus conveying the lithium battery powder through the connecting pipe 217 into the reactor body 201. Afterwards, the rotary motor 216 is stopped, and the rotary motor 224, air pump 202, and vibration motor 210 are activated. The power provided by the rotary motor 224 drives the third conical wheel 225 to rotate, which in turn drives the first conical wheel 222 and the second conical wheel 223 to rotate in opposite directions. These, in turn, drive the shearing frame 220 and the stirring frame 206 to rotate. The shearing frame 220 shears the lithium battery powder, while the counter-rotating stirring frame 206 mixes the powder, thus achieving the desired effect. The lithium battery powder undergoes shear mixing. During this process, the air pump 202 draws external gas into the connecting box 203, dehumidifies it through the drying plate 204, and then sends it into the conveying pipe 205. The gas then passes through the stirring rack 206 and the air outlet 208 before being discharged into the reactor body 201. This causes the lithium battery powder to tumble and collide under the airflow, dispersing agglomerates. Simultaneously, the vibration motor 210 breaks down the inter-particle interactions within the agglomerates, reducing agglomeration and enhancing the shear mixing effect. Once complete, the operator remotely opens the solenoid valve 227 to discharge the lithium battery powder from the reactor body 201, facilitating subsequent processing.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
