Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a new energy vehicle battery raw material mixing device. Background Art

[0002] As we all know, the performance of new energy vehicle batteries depends largely on the quality and uniformity of their electrode materials. A suitable mixing process can improve the physical and chemical properties of battery raw materials. During the mixing process, the interaction between raw materials can make the particles contact better.

[0003] The battery raw material mixing device can fully mix a variety of raw materials such as positive and negative electrode materials (such as lithium cobalt oxide, lithium iron phosphate and other positive electrode materials and graphite and other negative electrode materials), binders (such as polyvinylidene fluoride), conductive agents (such as carbon black), etc. Through stirring, tumbling and other methods, these raw materials are evenly distributed at the microscopic level to ensure that each part of the electrode material has similar composition and performance, thereby improving the consistency of the battery electrodes. For example, when preparing the positive electrode material of a lithium-ion battery, the electrode sheet made by evenly mixing the active substance, binder and conductive agent can conduct ions and electrons more stably during the battery charging and discharging process, thereby improving the battery's charging and discharging performance and cycle life.

[0004] However, in the existing technology of new energy vehicle battery raw material mixing devices, most of them adopt a single stirring structure. Due to the lack of dispersion ability, it is impossible to quickly and effectively break up and disperse the stubborn agglomerated particles, resulting in uneven mixing of the raw materials, affecting the mixing effect of the battery raw materials, and thus reducing the battery's charge and discharge performance and cycle life. Moreover, the single stirring structure is prone to the accumulation of heavy or large particles of raw materials at the bottom, which cannot fully contact and fuse with other raw materials, which makes the overall mixing uniformity of the battery raw materials poor, which not only causes unstable battery performance, but also affects the mixing efficiency.

[0018] 1. The new energy vehicle battery raw material mixing device drives the mixing shaft to rotate through the working of the mixing motor, which can drive the high-speed dispersing paddle assembly to rotate. Since the high-speed dispersing paddle assembly includes components such as a circular turntable, an upper dispersing blade and a lower dispersing blade, the circular turntable, the upper dispersing blade and the lower dispersing blade can be rotated, so that the agglomerated particles of the upper battery raw materials can be quickly dispersed by the rotation of the upper dispersing blade and the lower dispersing blade, and the high-speed rotation of the upper dispersing blade and the lower dispersing blade can generate a strong shear force to disperse the particles quickly; at the same time, the agglomerated particles in the upper battery raw materials will flow downward during the dispersion, and the rotation of the mixing shaft will also drive the spiral-type stirring paddle assembly to rotate. Since the spiral-type stirring paddle assembly includes components such as a stirring rod, a spiral-type stirring blade and a U-shaped stirring head, the spiral-type stirring paddle assembly will further spirally flip and mix the lower raw materials when it rotates, so as to ensure that raw materials with different densities and particle sizes can be fully mixed at the bottom of the container. Finally, through the synergistic effect of the upper and lower stirring components, the mixing efficiency can be greatly improved and the mixing time can be reduced;

[0019] 2. The new energy vehicle battery raw material mixing device can also be provided with a swing mixing mechanism, so that the mixing tank can swing back and forth based on the rotating shaft on the support frame by rotating the connecting piece, so that the battery raw materials in the mixing tank can be further swung and mixed by swinging the mixing tank back and forth;

[0020] 3. The new energy vehicle battery raw material mixing device can coordinate the swing mixing of battery raw materials, the rapid dispersion of battery raw materials, and the spiral turning mixing at the same time, so that the raw materials at different positions can be fully and evenly mixed, and the mixing efficiency is improved, avoiding the difficulty in the prior art of using a single stirring structure to quickly and effectively crush and disperse the agglomerated particles in the raw materials, thereby causing uneven mixing of raw materials, affecting the mixing effect of battery raw materials, and further reducing the battery charging and discharging performance and cycle life. At the same time, it can also avoid the situation in the past where the raw materials are easily accumulated at the bottom due to the use of a single stirring structure and it is difficult to fully contact and fuse with other raw materials. Ultimately, it can greatly improve the mixing uniformity of the battery raw materials and ensure the subsequent battery performance;

[0021] To sum up, the present invention adopts a multi-layer stirring structure, and its upper stirring structure is designed as a high-speed dispersion structure for quickly breaking up the agglomerated particles in the battery raw materials. Its high-speed rotation can generate a strong shear force to quickly disperse the particles. At the same time, the lower stirring structure is a spiral belt design as a whole, which can turn and mix the entire material to ensure that raw materials of different densities and particle sizes can be fully mixed at the bottom of the container.

[0037] See also Figure 2-3 , a swing mixing mechanism comprises a linkage mounting plate 10 movably arranged on the left side of the support frame 2, a linkage column 9 is fixedly connected to the top right side of the linkage mounting plate 10, the right end of the linkage column 9 slides in the horizontal direction to penetrate to the right side of the support frame 2 and is rotatably connected to a linkage slide seat 18, a slide rail 19 is fixedly arranged on the left side of the mixing tank 3, and the linkage slide seat 18 is slidably installed on the slide rail 19; a mounting shell 11 is fixedly installed on the left side of the linkage mounting plate 10, a screw motor 12 is fixedly installed in the mounting shell 11, the output shaft of the screw motor 12 rotates to penetrate to the right side of the linkage mounting plate 10 and is fixedly connected to a linkage screw rod 13, a screw nut 14 is fixedly installed on the support frame 2, and the linkage screw rod 13 is threadedly connected to the screw nut 14.

[0039] A controller 8 is disposed on the left side of the support frame 2 , and the controller 8 is electrically controlled and connected to the mixing motor 4 and the screw motor 12 .

[0040] like Figure 1-6As shown, the new energy vehicle battery raw material mixing device, when mixing the new energy vehicle battery raw materials in the mixing tank 3, uses the mixing motor 4 to drive the mixing shaft 5 to rotate, and when the mixing shaft 5 rotates, it will drive the high-speed dispersing paddle assembly 6 to rotate. Since the high-speed dispersing paddle assembly 6 includes components such as a circular turntable 601, an upper dispersing blade 601 and a lower dispersing blade 602, the circular turntable 601, the upper dispersing blade 601 and the lower dispersing blade 602 can be rotated, so that the agglomerated particles of the upper layer of battery raw materials can be quickly dispersed by the rotation of the upper dispersing blade 601 and the lower dispersing blade 602, such as the powder particle agglomerates in the positive and negative electrode materials. The high-speed rotation of the blade 601 and the lower dispersing blade 602 can generate a strong shear force to quickly disperse the particles; then the agglomerated particles in the upper layer of battery raw materials will flow downward during the dispersion.

Since the screw-belt stirring paddle assembly 7 includes components such as a stirring rod 701, a screw-belt stirring blade 702 and a U-shaped stirring head 703, the screw-belt stirring paddle assembly 7 will further spirally mix the lower layer of raw materials when it rotates, so as to ensure that raw materials of different densities and particle sizes can be fully mixed at the bottom of the container. In this way, through the synergistic effect of the upper and lower stirring components, the mixing efficiency can be greatly improved and the mixing time can be reduced.

[0041] At the same time, the screw motor 12 in the swing mixing mechanism can also be used to drive the linkage screw 13 to rotate forward and reverse, so that the linkage screw 13 can be driven to and fro in the horizontal direction based on the screw nut 14. When the linkage screw 13 moves left and right, it also drives the linkage mounting plate 10 and the linkage column 9 to move left and right. When the linkage column 9 moves, it will slide with the slide rail on the mixing tank 3 through the linkage slide seat 18, so that the mixing tank 3 can be swung back and forth (such as the rotating shaft 304 on the support frame 2 is the center) by rotating the connecting piece 303. Figure 6 As shown in , by swinging the mixing tank 3 back and forth, the battery raw materials in the mixing tank 3 can be further swung and mixed, and the swung mixing of the battery raw materials and the rapid dispersion of the battery raw materials and the spiral mixing can be coordinated at the same time, which not only can fully and evenly mix the raw materials at different positions, but also improves the mixing efficiency, avoids the prior art that it is difficult to quickly and effectively crush and disperse the agglomerated particles in the raw materials due to the use of a single stirring structure, thereby causing uneven mixing of the raw materials, affecting the mixing effect of the battery raw materials, and further reducing the battery charging and discharging performance and cycle life. At the same time, it can also avoid the situation in the past where the raw materials at the bottom are easily accumulated due to the use of a single stirring structure and it is difficult to fully contact and fuse with other raw materials. Ultimately, the mixing uniformity of the battery raw materials can be greatly improved, ensuring the subsequent battery performance.

[0042] To sum up, the present invention adopts a multi-layer stirring structure, and its upper stirring structure is designed as a high-speed dispersion structure for quickly breaking up the agglomerated particles in the battery raw materials. Its high-speed rotation can generate a strong shear force to quickly disperse the particles. At the same time, the lower stirring structure is a spiral belt design as a whole, which can turn and mix the entire material to ensure that raw materials of different densities and particle sizes can be fully mixed at the bottom of the container. The synergistic effect of the upper and lower multi-layer stirring structures, coupled with the cooperation of the left and right swinging mixing structure, can greatly improve the mixing efficiency, reduce the mixing time, ensure the overall mixing effect is better, and ensure the quality of new energy vehicle batteries, which is suitable for promotion and use.
