Abstract
Description
Technical Field
[0001] The utility model relates to the field of graphite anode materials, in particular to a demagnetization device for graphite anode materials. Background Technique
[0002] Graphite anode materials generally refer to graphite materials used in electrochemical applications such as lithium-ion batteries, especially materials used as anodes of lithium-ion batteries. Graphite has the following characteristics and advantages as a battery anode material: High electrical conductivity: Graphite has good electrical conductivity, which can effectively conduct electrons, thereby improving the electrical conductivity of the battery. Stability: Graphite has good chemical stability and structural stability during the electrochemical process, and can stably carry out battery reactions for a long time without easy structural damage or loss. Reversibility: Graphite can repeatedly undergo the processes of lithium-ion insertion and extraction, with good reversibility, which is one of the important characteristics of its use as an anode material for lithium-ion batteries. Cost-effectiveness: Graphite has a lower cost compared to some other high-performance anode materials (such as silicon), which can reduce the cost of battery manufacturing. Capacity: Although the specific capacity of graphite is relatively low, its stability and reliability make it widely used in commercial lithium-ion batteries. In lithium-ion batteries, graphite anode materials are mainly used to store and release lithium ions, thereby providing the charge and discharge functions of the battery. With the rise of electric vehicles and renewable energy, the research and development and optimization of graphite anode materials are still one of the important fields in the development of battery technology.
[0003] After retrieval, a demagnetization device for graphite anode materials with the publication number CN209697155U includes a box body.

At the same time, by controlling the rotation of the stirring tube and the stirring teeth, the materials in the box can be fully demagnetized, which is suitable for large-scale operation. When the materials enter the box through the feeding pipe, they are first blocked by the arc-shaped plate, and the arc-shaped plate can make the materials disperse evenly around, which is beneficial to the full contact between the materials and the stirring tube and the stirring teeth, improving the demagnetization effect.

[0025] Refer to Figure 1 and Figure 2 As shown in [drawings not specified in the original text] and [drawings not specified in the original text], an embodiment provided by the present invention: A demagnetization device for graphite anode materials includes a barrel body 1. A barrel cover 2 is connected to the top side of the barrel body 1. A motor 5 is installed on the top side of the barrel cover 2. The middle end inside the barrel cover 2 is rotatably connected to a rotating rod 9. The driving end of the motor 5 is fixedly connected to the top end of the rotating rod 9. A cross bar 10 is fixedly connected to the outer wall of the rotating rod 9. A plurality of stirring blades 11 are fixedly connected to the outer wall of the rotating rod 9.

A feeding port 4 is fixedly connected to the top side of the barrel cover 2. Three support columns are fixedly connected to the bottom side of the barrel body 1.
[0026] Specifically, the graphite anode material to be demagnetized is added into the barrel body 1 through the feeding port 4, and then the rotating rod 9 is electrified to generate a magnetic field, so as to demagnetize the graphite anode material inside the barrel body 1. The motor 5 is used to drive the rotating rod 9 to rotate, so that the stirring blades 11 rotate. At the same time, when the rotating rod 9 rotates, the cross bar 10 will also rotate in the barrel body 1. After demagnetization is completed, the graphite anode material is discharged from the barrel body 1 through the discharge port 15.
[0027] Refer to Figure 1 and Figure 4 As shown in [drawings not specified in the original text] and [drawings not specified in the original text], limit grooves 7 are fixedly connected to the left and right sides of the top side of the barrel body 1. Chute grooves are opened on the left and right sides of the top side of the barrel cover 2. Slide blocks 19 are slidably connected inside the chute grooves. A rack 6 is fixedly connected to the top side of the slide block 19. A buckle block 3 is fixedly connected to the end of the rack 6.

The bottom end of the damping shaft 17 is rotatably connected inside the barrel cover 2. The top end of the damping shaft 17 is fixedly connected to a turning handle 16.
[0028] Specifically, by rotating the handle 16, the damping shaft 17 is rotated, thereby rotating the first gear 18. Then, the first gear 18 is rotated to drive the rack 6 to slide, so that the buckle block 3 at the end of the rack 6 is engaged in the limit groove 7 or the buckle block 3 is disengaged from the limit groove 7, thus completing the installation or disassembly between the bucket lid 2 and the bucket body 1, and cleaning the residue inside the bucket body 1 to prevent the residue from affecting the next demagnetization.

[0030] Specifically, by rotating the cross bar 10, the second gear 14 rotates in the bucket body 1 under the action of the teeth 8, thereby driving the round rod 13 to rotate, so that the spiral disk 12 rotates, and the graphite anode material at the bottom of the bucket body 1 is stirred to the upper layer, making the graphite anode material more uniform and the demagnetization more thorough.
[0031] Working principle: The graphite anode material to be demagnetized is added into the bucket body 1 through the feeding port 4, and then the rotating rod 9 is electrified to generate a magnetic field, so as to demagnetize the graphite anode material inside the bucket body 1. The motor 5 is used to drive the rotating rod 9 to rotate, so that the stirring piece 11 rotates. At the same time, when the rotating rod 9 rotates, the cross bar 10 also rotates in the bucket body 1, so that the second gear 14 rotates in the bucket body 1 under the action of the teeth 8, thereby driving the round rod 13 to rotate, so that the spiral disk 12 rotates, and the graphite anode material at the bottom of the bucket body 1 is stirred to the upper layer, making the graphite anode material more uniform and the demagnetization more thorough. When the demagnetization is completed, the graphite anode material is discharged from the bucket body 1 through the discharge port 15.
