[0026] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0027] Combination Figures 1 to 8 As shown, the isostatic pressing graphite raw material grinding device of this utility model includes an outer shell 1, a hopper 2 and a lower shell 4. The hopper 2 is provided on the top of the outer shell 1, and a return bucket 3 is provided on one side of the outer shell 1. The lower shell 4 is fixed inside the outer shell 1. The upper shell 5 is provided on the top of the lower shell 4. An adjustment component is provided on the outer periphery of the lower shell 4. A grinding component is provided inside the lower shell 4. A screening component is provided below the lower shell 4. A material box 7 is installed on the inner bottom wall of the outer shell 1.

[0028] The grinding assembly includes a grinding block 51 installed on the top of the upper housing 5, the grinding block 51 being positioned on the inner top wall of the upper housing 5, a grinding disc 42 being rotatably mounted inside the lower housing 4, a base frame 43 being mounted at the bottom of the grinding disc 42, the base frame 43 being fixed inside the lower housing 4, the grinding disc 42 being rotatably mounted on the top of the base frame 43, a second motor 44 being mounted at the middle position of the bottom of the base frame 43, the rotating shaft at the top of the second motor 44 protruding from the top of the base frame 43 and connected to the middle position of the bottom of the grinding disc 42.

[0029] The distance adjustment assembly includes multiple telescopic rods 52 installed on the outer side wall of the lower housing 4. The output end of the top of the telescopic rod 52 is fixedly connected to the outer edge of the bottom of the upper housing 5. A guide groove 45 is provided on the outer side wall of the lower housing 4. A guide block 46 is provided in the guide groove 45. The guide block 46 is fixed on the inner side wall of the upper housing 5. A laser particle size sensor 41 is installed on the side wall at the bottom of the lower housing 4.

[0030] The screening assembly includes a filter box 6 located below the lower housing 4, which is directly above the material box 7. Springs 62 are provided on both sides of the filter box 6, and a bracket 61 is fixed to the bottom of the springs 62. The bracket 61 is fixed to the inner bottom wall of the outer housing 1. A vibration motor 63 is installed at one end of the bottom of the filter box 6, and a connecting pipe 35 is connected to the other end of the filter box 6. The connecting pipe 35 protrudes from the inside of the outer housing 1 to its outer wall.

[0031] The return material bin 3 is equipped with a rotating spiral roller 34 inside. A motor 33 is installed on the top of the return material bin 3. The rotating shaft at the bottom of the motor 33 extends into the return material bin 3 and is fixedly connected to the rotating shaft at the top of the spiral roller 34. A feed pipe 31 is connected to the bottom end of one side of the return material bin 3. The feed pipe 31 is connected to the connecting pipe 35. A discharge pipe 32 is connected to the top end of one side of the return material bin 3. The discharge pipe 32 is connected to the inside of the hopper 2.

[0032] Specifically, after the operator starts the entire system, the pre-treated coke particles are first fed into hopper 2. The coke particles enter the interior of the upper shell 5 along the inner wall of hopper 2;

[0033] After the coke particles enter the upper shell 5, they fall into the gap between the grinding disc 42 and the grinding block 51. Driven by the motor 44, the grinding disc 42 begins to rotate at a stable and efficient speed. As the grinding disc 42 rotates, the coke particles are subjected to strong compression and shearing forces between the grinding disc 42 and the grinding block 51, gradually grinding the coke particles into fine powder.

[0034] During the grinding process, the laser particle size sensor 41 continuously detects the fine powder discharged from the bottom feed pipe of the lower housing 4. Utilizing advanced laser scattering principles, it can quickly and accurately detect the particle size distribution of the powder in real time. The laser particle size sensor 41 rapidly transmits the detected particle size data to the PLC (Programmable Logic Controller).

[0035] The PLC pre-stores a series of preset standards. Upon receiving particle size data, the PLC quickly performs comparative analysis. If the detected powder particle size does not meet the preset standards, the PLC immediately issues instructions to precisely adjust the rotation speed of the grinding disc 42 and the spacing between the grinding block 51 and the grinding disc 42.

[0036] When reducing the distance between the grinding block 51 and the grinding disc 42, the telescopic rod 52 is activated. The telescopic rod 52 uses hydraulic drive technology, enabling smooth and precise extension and retraction. As the telescopic rod 52 extends, the upper housing 5 slowly moves downwards. During this downward movement, the guide block 46 moves synchronously downwards within the guide groove 45. The guide groove 45 and the guide block 46 guide the vertical movement of the upper housing 5. This guiding action ensures the stability of the upper housing 5 during its vertical movement, preventing swaying and deviation, thereby guaranteeing the accuracy of the distance adjustment between the grinding block 51 and the grinding disc 42.

[0037] After grinding, the powder falls into the filter box 6. Under the action of the vibrating motor 63, the screen inside the filter box 6 begins to vibrate at a high frequency. This vibration can effectively accelerate the sieving process of the powder, so that qualified powder can quickly pass through the screen and fall into the storage bin 7.

[0038] The substandard powder cannot pass through the sieve and enters the return hopper 3 through the connecting pipe 35 and the feed pipe 31. The motor 33 drives the spiral roller 34 to rotate, and the spiral roller 34 gradually lifts the substandard powder. Finally, the substandard powder is reintroduced into the hopper 2 through the discharge pipe 32 to participate in the grinding work again, forming a cyclical, efficient and precise production process.
