Description

Technical Field

[0001] The utility model relates to the technical field of graphite processing, in particular to a dust-proof discharging structure for graphite ball raw material crushing. Background Art

[0002] Graphite is a crystalline carbon. It is widely used in various fields due to its advantages such as light weight, high thermal conductivity, self-lubrication at high temperature, and wear resistance. Spherical graphite is made from high-quality high-carbon natural flake graphite. The graphite surface is modified through a series of processing techniques to produce graphite products shaped like ellipsoidal spheres.

[0003] When processing spherical graphite, it is usually necessary to crush the spherical graphite raw materials. When the crushed graphite raw materials are discharged, the graphite powder has a small diameter, which makes it easy for the graphite powder to diffuse in the air during discharge. After the operators inhale these graphite powders, they are prone to diseases such as "pneumoconiosis". In addition, the flying graphite powders adhere to the surrounding equipment and the site, making it difficult to clean.

[0004] Therefore, it is necessary to design a dust-proof discharging structure for graphite ball raw material crushing. Utility Model Content

[0028] See also Figure 2 and Figure 3 As shown, the crushing assembly includes a servo motor 4, a crushing roller 5, a gear 8 and a second protective plate 7. The servo motor 4 is installed on the left side of the crushing box 3 by bolt connection. Two crushing rollers 5 are rotatably arranged in the crushing box 3. The output shaft of the servo motor 4 passes through the crushing box 3 and is connected to the crushing roller 5 on the rear side through a coupling. First protective plates 6 are installed on both sides of the crushing roller 5. The cross-section of the first protective plate 6 is arc-shaped. The crushing roller 5 rotates between the two first protective plates 6. The first protective plate 6 can reduce the gap between the crushing roller 5 and the inner wall of the crushing box 3, so as to facilitate the crushing of the graphite ball raw material. The second protective plate 7 is installed on the right side of the crushing box 3, and the roller shafts of the two crushing rollers 5 pass through the second protective plate 7. One end of the crushing roller 5 passing through the second protective plate 7 is fixedly connected with a gear 8 by a key connection, and the two gears 8 are meshed with each other.

[0029] When the graphite ball raw material needs to be crushed, the servo motor 4 is started first, and the output shaft of the servo motor 4 drives one of the crushing rollers 5 to rotate. The two crushing rollers 5 are meshed and driven by the gear 8, so that the two crushing rollers 5 rotate in opposite directions. Then, the graphite ball raw material is added into the crushing box 3, and the two crushing rollers 5 rotate in opposite directions to crush the graphite ball raw material. At the same time, the fan 16 and the air pump 10 are started. The air pump 10 sucks the gas under the crushing box 3 through the air pipe 14 and the annular air guide pipe 12. When the crushed graphite When the ball raw material falls downward through the crushing box 3 and generates dust, the air nozzle 13 sucks the dust at the bottom of the crushing box 3 to prevent the dust from spreading when the graphite ball raw material is discharged.
