Description

Technical Field

[0001] The present application relates to the technical field of graphite electrode roasting, and in particular to a furnace discharge device for graphite electrode roasting. Background Art

[0002] During the processing of graphite electrodes, they need to be roasted. Among them, there are covered ring roasting furnaces, open ring roasting furnaces, and tunnel kilns for roasting, and natural gas is mainly used as fuel.

[0003] Existing graphite electrodes need to be transferred using a furnace unloading device after roasting. Among them, the current furnace unloading devices mostly use a combination of ropes and clamps to clamp and transport the middle part of the graphite electrode. Since the rope is prone to swing during transportation, the graphite electrode is also prone to swing, and the two ends of the graphite electrode lack tools for limiting the position, resulting in poor stability of the graphite electrode during transportation out of the furnace, and there is a risk of sliding in the axial direction. Since the graphite electrode is in a high temperature state at this time, once it falls off, it may cause a safety hazard to the workers. For this reason, the present application provides a furnace unloading device for graphite electrode roasting. Utility Model Content

The graphite electrode is in a high temperature state at this time, and once it falls off, it may cause a safety hazard to the workers.

At this time, the electric push rod 9 extends to drive the automatic clamp 10 to clamp the graphite electrode body 11, and then the electric push rod 9 contracts to drive the graphite electrode body 11 to rise. When the graphite electrode body 11 rises and is placed between the two groups of L-shaped brackets 12, the two ends of the graphite electrode body 11 are respectively in contact with the inclined plates 16. When the graphite electrode body 11 rises to exceed the height of the rotating shaft 15, the inclined plates 16 rotate under the action of the rotating shaft 15. At this time, the two groups of inclined plates 16 are arranged in an inverted eight shape, so that the two groups of inclined plates 16 can support the two ends of the graphite electrode body 11.

One end of the telescopic guide rod 21 is fixedly mounted on the side wall of the L-shaped bracket 12.

This structure is simple, stable and efficient, and improves the practicality during use. In addition, the connecting mechanism 7 is a connecting rod, which avoids the conventional rope from causing the graphite electrode to swing, which is beneficial to improving the safety performance of the graphite electrode when moving. The graphite electrode body 11 with a longer diameter is convenient for squeezing the inclined plate 16, and the spring 13 is squeezed and compressed to drive the inclined plate 16 to move, and the graphite electrode body 11 can rise smoothly. The position of the inclined plate 16 can be adjusted by the spring 13, which is suitable for graphite electrode bodies 11 of various lengths.

Then the electric push rod 9 contracts and drives the graphite electrode body 11 to rise. When the graphite electrode body 11 rises and is placed between the two groups of L-shaped brackets 12, the two ends of the graphite electrode body 11 are in contact with the inclined plate 16 respectively. When the graphite electrode body 11 rises to exceed the height of the rotating shaft 15, the inclined plate 16 rotates under the action of the rotating shaft 15.

By using the connecting mechanism 7 as a connecting rod, it is avoided that the conventionally used rope causes the graphite electrode to swing, which is beneficial to improving the safety performance of the graphite electrode when it is moved;

[0034] At the same time, when the graphite electrode is clamped, the buffer spring 20 provides a good buffering effect between the graphite electrode body 11 and the automatic clamp 10, thereby effectively protecting the outer wall of the graphite electrode;
