Description

Technical Field

[0001] This utility model belongs to the field of lithium battery raw material crushing technology, and in particular relates to an ultrafine grinding device for lithium battery raw material grinding. Background Technology

[0002] With the rapid development of the new energy industry, lithium batteries are widely used in electric vehicles, energy storage systems, and consumer electronics due to their high energy density, long cycle life, and environmentally friendly characteristics. During the preparation of lithium battery positive and negative electrode materials, the raw materials typically need to be pulverized into fine powder to improve the reactivity of the electrode materials and the battery performance.

[0003] However, in existing crushing operations, the feeding of raw materials and the unloading of fine powder still rely heavily on manual operation. Operators need to manually carry raw materials from the previous production line and pour them into the crushing device. After crushing, the powder in the device needs to be collected and transferred to the next production line. This mode not only brings huge labor intensity, but also causes environmental pollution and waste of raw materials due to dust flying during the raw material handling and powder transfer process, and increases the occupational health risk of operators inhaling dust.

[0004] Therefore, it is necessary to design an ultrafine grinding device for lithium battery raw materials to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing crushing operations, such as high labor intensity, low efficiency, dust pollution, raw material waste and occupational health risks due to manual loading and unloading, this utility model provides an ultrafine crushing device for grinding lithium battery raw materials.

Motor 4 is located at the front right of the outer shell 2. The output shaft of motor 4 extends horizontally to the right, and gear 41 is fixedly connected to the output shaft. Gear 41 is located in front of gear 35 and meshes with gear 35. Gear 35 is a large gear and gear 41 is a small gear, which can realize speed reduction transmission, thereby providing stable, low-speed rotational power for the inner barrel 3. The axial thickness of gear 35 and gear 41 is equal. Controller 7 is bolted to the top of the base 1. Controller 7 is located at the front of the outer shell 2. Motor 4 is electrically connected to controller 7. Controller 7 is a programmable logic controller, model Huichuan Easy 521-24T4DT.

[0021] like Figure 1 , Figure 5 and Figure 6As shown, the top of the base 1 is equipped with a loading and unloading assembly, which includes a support frame 5, a second motor 51, a first conveyor roller 52, a first conveyor belt 53, a support plate 6, a third motor 61, a second conveyor roller 62, and a second conveyor belt 63. The support frame 5 is fixedly connected to the right side of the top of the base 1. The support frame 5 is located to the right of the outer shell 2. The second motor 51 is bolted to the upper part of the support frame 5. Two symmetrically arranged first conveyor rollers 52 are rotatably mounted on the upper part of the support frame 5. The output shaft of the second motor 51 extends horizontally backward and is fixedly connected to the front end of the first right conveyor roller 52. The first conveyor belt 53 is rotatably mounted between the two first conveyor rollers 52. The upper left part of the support frame 5 extends into the inner part through the feed inlet 31. Inside the barrel 3, the left side of the conveyor belt 53 extends into the inner barrel 3 through the feed inlet 31 to realize automatic and continuous feeding of raw materials. The top of the base 1 is connected by bolts to two support plates 6 arranged in front and behind. The left side of the front support plate 6 is connected by bolts to the motor 61. Both the second motor 51 and the third motor 61 are electrically connected to the controller 7. Two symmetrically arranged conveyor rollers 62 are rotatably arranged between the lower parts of the two support plates 6. The output shaft of the third motor 61 extends horizontally backward and is fixedly connected to the front end of the left conveyor roller 62. A conveyor belt 63 is rotatably arranged between the two conveyor rollers 62. The conveyor belt 63 is located below the discharge port 21 to accurately receive the powder discharged from the discharge port 21.

[0022] In use, this device is positioned between the previous and next production lines, with conveyor belt 53 connected to the previous production line and conveyor belt 63 connected to the next production line. The operator then adds an appropriate amount of steel balls into the inner drum 3. The controller 7 sequentially starts motors 4, 51, and 61. When the previous production line delivers the raw material to be crushed onto conveyor belt 53, the output shaft of motor 51 drives the right conveyor roller 52 to rotate counterclockwise. The right and left conveyor rollers 52 work together to stably pull conveyor belt 53 counterclockwise (viewed from the front of support plate 6), conveying the raw material to the left into the inner drum 3. The raw material falls from the leftmost end of conveyor belt 53 into the inner drum 3. At this time, the output shaft of motor 4 drives gear 41 to rotate clockwise. Engaging with gear 35, the drive gear 35 rotates the inner barrel 3 counterclockwise. When the inner barrel 3 rotates, the steel balls inside move along with the barrel wall and are carried to a certain height before falling freely due to gravity. The raw materials are crushed through impact and grinding. During the crushing process, powder with a particle size smaller than the aperture of filter screen 33 passes through filter screen 33 and then through baffle 22 onto conveyor belt 63. At this time, the output shaft of motor 61 drives the left conveyor roller 62 to rotate counterclockwise. The left and right conveyor rollers 62 work together to stably pull conveyor belt 63 to rotate counterclockwise, conveying the raw materials to the left to the next production line. When the raw materials are crushed and conveyor belt 63 has delivered all the powder to the next production line, motors 4, 51, and 61 are turned off in sequence.
