[0025] Such as Figures 1 to 4As shown in the figure, a hermetic sand mill for sodium-ion batteries includes a base 1. On the left side of the top surface of the base 1, a column 2 is fixedly connected. The end of the column 2 is rotatably connected to a support base 3. On the top surface of the support base 3, a sand grinding cylinder 5 is fixedly connected. Inside the base 1, there is an inclined mixing component 4 for controlling the inclination of the support base 3. On the surface of the sand grinding cylinder 5, there is a grinding component 6 for grinding the carbon nanotube slurry. On the surface of the support base 3, there is a feeding component 7 for agitating the slurry. On the top surface of the sand grinding cylinder 5, a feeding hopper 8 is fixedly connected. On the right side surface of the sand grinding cylinder 5, a discharge pipe 9 is fixedly inserted. More specifically, the carbon nanotube slurry and abrasive particles are added into the interior of the sand grinding cylinder 5 from the feeding hopper 8. By operating the grinding component 6, the carbon nanotube slurry and abrasive particles are driven to rotate, and the carbon nanotube slurry is ground. By operating the feeding component 7, the slurry can be pushed to move horizontally to avoid the accumulation of the slurry. Then, by operating the inclined mixing component 4, the right end of the support base 3 is driven to rotate up and down reciprocally, thereby driving the sand grinding cylinder 5 to shake, and then the slurry inside the sand grinding cylinder 5 can be driven to shake, assisting the slurry to move and mix continuously.

[0026] The inclined mixing component 4 includes a first motor 401, and the first motor 401 is fixedly installed on the left side surface of the base 1. The output end of the first motor 401 is fixedly connected to a reciprocating threaded rod 402. A mounting plate 403 is threadedly connected to the surface of the reciprocating threaded rod 402.

The end of the support rod 404 is rotatably connected to a cross bar 405, and the cross bar 405 is fixedly connected to the bottom surface of the support base 3. It should be noted that by driving the reciprocating threaded rod 402 to rotate by the first motor 401, under the action of the thread, the mounting plate 403 will be driven to reciprocate along the surface of the sliding column 406, thereby pushing the bottom end of the support rod 404 to move. The top end of the support rod 404 will pull the cross bar 405 to move, thereby driving the right end of the support base 3 to rotate reciprocally.

[0027] The grinding component 6 includes a second motor 601, and the second motor 601 is fixedly installed on the surface of the sand grinding cylinder 5. The output end of the second motor 601 is fixedly connected to a rotating shaft 602. A grinding wheel 603 is fixedly connected to the surface of the rotating shaft 602.

It should be noted that by operating the third motor 702, the lead screw 703 is driven to rotate. Under the action of the thread, the connecting rod 704 will be driven to move. The material pushing ring 705 is pushed by the connecting rod 704 to slide along the inner wall of the grinding cylinder 5, so as to push the slurry to move along the inner wall of the grinding cylinder 5, prevent the slurry from accumulating at a certain place, and strengthen the flow of the slurry.

[0029] The material pushing ring 705 is of an annular structure, and the inner diameter of the material pushing ring 705 is larger than the diameter of the grinding wheel 603. More specifically, by setting a larger inner diameter, the material pushing ring 705 is prevented from colliding with the grinding wheel 603 during the moving process.

[0030] Valves are provided inside both the feeding hopper 8 and the discharge pipe 9. It should be noted that by providing the valves, the slurry is prevented from overflowing from the inside of the feeding hopper 8 or the discharge pipe 9 during the grinding process.

[0031] In summary: The carbon nanotube slurry and abrasive particles are added into the grinding cylinder 5 from the feeding hopper 8. By operating the grinding assembly 6, the carbon nanotube slurry and abrasive particles are driven to rotate, and the carbon nanotube slurry is ground. By operating the material pushing assembly 7, the slurry can be pushed to move horizontally to prevent the slurry from accumulating. Then, by operating the inclined mixing assembly 4, the right end of the support base 3 is driven to rotate up and down reciprocally, so as to drive the grinding cylinder 5 to shake, and then the slurry inside the grinding cylinder 5 can be driven to shake, assisting the slurry to move and mix continuously. The effect of facilitating the effective grinding process of the carbon nanotube slurry is achieved during use. During the grinding process, the slurry can be disturbed to prevent the slurry from accumulating at the corners, thereby ensuring the uniformity of the slurry grinding.
