Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrode shot blasting, in particular to a shot blasting device used before graphite electrode impregnation. Background Art

[0002] Shot blasting machine is a processing technology that uses a shot blaster to throw steel sand and steel shots at high speed to impact the surface of material objects. Compared with other surface treatment technologies, it is faster and more effective, and can be used for partially retained or stamped casting processes. Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar as a binder, and are made through calcination, batching, kneading, pressing, roasting, graphitization, and machining. When producing graphite electrodes, shot blasting devices are required to remove sand, core and clean them, and increase their strength, so as to achieve greater safety and reliability in later use.

[0003] When the graphite electrode is shot blasted, the cylindrical graphite electrode is usually hoisted onto the conveyor roller, and then the conveyor roller is started to convey the graphite electrode into the shot blasting room. There is an angle between the axis of the drive roller on the conveyor roller and the conveying direction of the graphite electrode, so that the friction of the drive roller on the graphite electrode produces two effects, one is to drive the graphite electrode to move linearly along the conveying direction, and the other is to drive the graphite electrode to rotate around its axis, so that the outer surface of the graphite electrode can be made smooth in the shot blasting room. However, this conveying method also has insurmountable drawbacks: first, when the graphite electrode is hoisted onto the conveyor roller, the conveying needs to be stopped, which causes the discontinuity of the shot blasting operation and reduces the production efficiency; second, the graphite electrode does not need to rotate when it is outside the shot blasting room, which will cause a large part of energy waste, increase production costs, and reduce corporate benefits. Utility Model Content

[0004] In order to solve the deficiencies mentioned in the above background technology, the purpose of the utility model is to provide a shot blasting device for graphite electrodes before impregnation. Through the combination of a linear conveying roller section and a rotating conveying roller section, the continuous conveying and self-rotation shot blasting of the graphite electrodes are realized, thereby improving production efficiency. At the same time, the design of the automatic feeding component makes the feeding process more automated and efficient, reduces manual intervention, and reduces production costs. In addition, the push block design of the multi-stage material distribution component can adapt to graphite electrodes of different lengths, thereby improving the versatility of the device.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0024] The multi-stage material distribution assembly includes a first push block 7, a second push block 8 and a third push block 9. The top of the first push block 7 is flush with the end of the stacking plate 3 close to it to ensure that the graphite electrode can smoothly enter the first push block 7. A bottom plate 10 is arranged below the first push block 7, and a first hydraulic rod 11 is arranged on the bottom plate 10. The output end of the first hydraulic rod 11 is connected to the first push block 7. A second hydraulic rod 12 is arranged on the bottom plate 10, and the output end of the second hydraulic rod 12 is connected to the second push block 8. A third hydraulic rod 13 is arranged on the bottom plate 10, and the output end of the third hydraulic rod 13 is connected to the third push block 9.

[0025] The bottom ends of the first push block 7 and the second push block 8 are symmetrically provided with slide bars 14, the slide bars 14 are slidably connected to the first push block 7 and the second push block 8, and the bottom ends of the slide bars 14 are fixedly connected to the bottom plate 10. The design of the slide bars 14 makes the push blocks more stable when pushing the graphite electrodes.

[0026] The heights of the first push block 7, the second push block 8 and the third push block 9 increase in sequence. The tops of the first push block 7, the second push block 8 and the third push block 9 are provided with an arc surface 15 on the side away from the stacking plate 3. The arc surface 15 is adapted to the shape of the graphite electrode. The graphite electrode can be stably prevented from detaching within the arc surface 15 through the arc surface 15. The second push block 8 and the third push block 9 are provided with an anti-collision strip 16 on the side close to the stacking plate 3. The second push block 8 and the third push block 9 are also provided with an anti-collision strip 16 on the side close to the stacking plate 3 to prevent the graphite electrode from colliding with the push block and being damaged during the pushing process.

[0027] The second push block 8 and the third push block 9 are both provided with a slide groove 17, and the first push block 7 and the second push block 8 are both fixedly connected with a connecting block 18, one end of the connecting block 18 on the first push block 7 extends to the inside of the slide groove 17 on the second push block 8, and one end of the connecting block 18 on the second push block 8 extends to the inside of the slide groove 17 on the third push block 9.

[0029] Working principle:

[0030] When using the device, a plurality of graphite electrodes are first placed flat on the stacking plate 3. When the shot blasting treatment is performed, the first hydraulic rod 11 is first started to push the graphite electrode on the first push block 7 to move upward. When the height of the first push block 7 exceeds the second push block 8, the graphite electrode will roll onto the second push block 8. Then the first push block 7 is reset, and the second hydraulic rod 12 pushes the graphite electrode on the second push block 8 to move upward. When the height of the second push block 8 exceeds the third push block 9, the graphite electrode will roll onto the third push block 9. Then the graphite electrode rolls onto the straight conveying roller section 1 and is then transported to the rotating conveying roller section 2. Since the rotating conveying roller section 2 is inclined relative to the straight conveying roller section 1, the rotating conveying roller rotates under the drive of the motor after the graphite electrode enters the rotating conveying roller section 2, which not only provides a forward driving force for the graphite electrode, but also decomposes a rotational force for rotating the graphite electrode, thereby driving the graphite electrode to rotate and move forward on the rotating conveying roller section 2, so as to ensure that the surrounding surfaces of the graphite electrode can be fully processed by parabolic treatment.
