[0001] This utility model relates to the field of graphite material grinding technology, and in particular to a grinding device for ultrafine particle low thermal expansion isostatic graphite materials. Background Technology

[0002] Graphite is a special type of carbon with good electrical conductivity. It is often used as the negative electrode material in batteries.

[0031] The graphite material grinding and processing assembly 1 includes an inclined discharge pipe 11, a rotating shaft 12, crushing blades 13, a grinding disc 14, and a grinding seat 15. The inclined discharge pipe 11 is fixedly installed inside the fixed cylinder 7, and the output end of the inclined discharge pipe 11 is fixedly installed on the rear side of the grinding box 6. The rotating shaft 12 is rotatably installed on the top of the grinding box 6. Multiple crushing blades 13 are fixedly installed around the outside of the rotating shaft 12. The grinding disc 14 is fixedly installed on the outside of the rotating shaft 12. The grinding seat 15 is fixedly installed on the bottom inner wall of the grinding box 6.

[0032] In this embodiment, a first motor 8 is fixedly installed at the bottom of the fixed frame 3, a drive shaft 9 is fixedly installed on the outside of the first motor 8, a feeding auger 10 is fixedly installed on the outside of the drive shaft 9, and a graphite material sieving and circulating assembly 2 is provided above the graphite material grinding and processing assembly 1.

[0033] In this embodiment, the graphite material grinding and processing assembly 1 further includes a main pulley 16, a secondary pulley 17, and a belt 18. The main pulley 16 is fixedly installed on the outside of the drive shaft 9, the secondary pulley 17 is fixedly installed on the outside of the rotating shaft 12, and the belt 18 is tensioned and sleeved on the outside of the main pulley 16 and the secondary pulley 17.

[0034] In this embodiment, the graphite material screening and circulation assembly 2 includes a limiting frame 21, a second motor 22, a lead screw 23, a moving plate 24, an electric telescopic rod 25, and a screening discharge box 26. The limiting frame 21 is fixedly installed on the top of the fixed frame 3, the second motor 22 is fixedly installed on the top inner wall of the limiting frame 21, the lead screw 23 is fixedly installed on the output end of the second motor 22, the moving plate 24 is threaded onto the outside of the lead screw 23, the electric telescopic rod 25 is fixedly installed on one side of the moving plate 24, and the screening discharge box 26 is fixedly installed on the output end of the electric telescopic rod 25.

[0035] In this embodiment, the graphite material screening and circulation assembly 2 further includes a guide ramp 27, a receiving groove 28, a guide rod 29, a spring 30, a screening plate 31, and a force-bearing plate 32. The guide ramp 27 is fixedly installed between the inner walls of the front and rear sides of the screening feed box 26. The receiving groove 28 is opened on the left side of the screening feed box 26. One end of the guide rod 29 and the spring 30 are fixedly installed on the inner wall of the right side of the receiving groove 28.

[0036] In this embodiment, the top of the grinding box 6 is provided with a feed hole, the size of which is larger than the size of the screening plate 31. The lead screw 23 can drive the moving plate 24 and the screening feed box 26 to rise, and control the electric telescopic rod 25 to drive the screening feed box 26 to move towards the grinding box 6, so that the force plate 32 below the screening feed box 26 abuts against the grinding box 6. During the movement of the screening feed box 26, the force plate 32 can drive the screening plate 31 to slide into the inner side of the receiving groove 28, so that the graphite particles in the screening feed box 26 can enter the inner side of the grinding box 6 for cyclic grinding.

[0037] In this embodiment, a guide groove is provided on one side of the screening plate 31, and the guide rod 29 fits into the guide groove.

[0038] In this embodiment, a feed trough is provided on the rear side of the grinding box 6, and an inclined discharge pipe 11 is fixedly installed inside the feed trough. The graphite material is lifted by the cooperation of the drive shaft 9, the feeding auger 10 and the inclined discharge pipe 11. The inclined discharge pipe 11 can transport the lifted graphite material to the inside of the grinding box 6 for grinding.

[0039] The specific operation is as follows: the material is placed inside the feeding box 4. The graphite material is fed into the grinding box 6 for grinding through the cooperation of the drive shaft 9, the feeding auger 10 and the inclined discharge pipe 11. During the rotation of the drive shaft 9, the multiple crushing blades 13 and the grinding disc 14 are driven through the cooperation of the main pulley 16, the auxiliary pulley 17 and the belt 18. The crushing blades 13 can crush the graphite material. The grinding disc 14 and the grinding seat 15 can grind the crushed graphite material. After grinding, the material can fall into the inner side of the screening feeding box 26 and be screened through the screening plate 31. The smaller graphite particles after screening can be discharged from the through hole above the fixed frame 3.

[0040] The electric telescopic rod 25 can move the screening feed box 26, allowing the graphite particles above the screening plate 31 to move, thus preventing the graphite particles from clogging the screening holes during the screening process. After the graphite material is ground, the second motor 22 can be controlled to drive the lead screw 23 to rotate. The lead screw 23 can drive the moving plate 24 and the screening feed box 26 to rise. The electric telescopic rod 25 is controlled to move the screening feed box 26 towards the grinding box 6, so that the force plate 32 below the screening feed box 26 abuts against the grinding box 6. During the movement of the screening feed box 26, the force plate 32 can drive the screening plate 31 to slide into the inner side of the receiving trough 28, which facilitates the graphite particles in the screening feed box 26 to enter the inner side of the grinding box 6 for cyclic grinding. This device does not require manual operation and has high working efficiency.
