Abstract
Description
Technical Field
[0001] This utility model belongs to the field of self-baking electrode insulation technology, specifically relating to a self-baking electrode phase-to-phase insulation device. Background Technology
[0002] Self-baking electrodes are made by mixing amorphous carbon, graphite, tar, and pitch in a specific ratio into a paste, which is then cooled, processed into blocks, and further crushed into suitable particle sizes before use. These blocks are then added to a specially designed electrode cylinder (shell) and baked using an external heating source, the electric furnace's own heat radiation and conduction, and the resistance heat generated by the current passing through the electrodes. During production, the self-baking electrodes are continuously consumed and sintered again using the heat generated during production, ensuring timely replenishment of the consumed material and maintaining stable furnace operation. Because the self-baking electrodes are electrically charged, they require insulation. Traditionally, wooden boards are used for insulation. However, in actual production, for self-baking electrodes operating at high currents, the large amount of resistance heat generated after power supply can easily cause the wooden boards to carbonize, posing a safety hazard. Therefore, a safe, reliable, simple, and practical interphase insulation device for self-baking electrodes needs to be developed. Utility Model Content

The support column is installed on an insulating platform with self-baking electrodes. The insulating tube is sleeved on the outside of the support column. One end of the insulating fireproof plate is connected to the insulating tube through a connector. The insulating fireproof plates are arranged between two adjacent self-baking electrodes to achieve phase-to-phase insulation between the self-baking electrodes. The insulating fireproof plate includes a fixed frame and a supporting thin plate. The inner side of the fixed frame is provided with a receiving groove adapted to the supporting thin plate. The supporting thin plate is disposed in the receiving groove. The surface of the supporting thin plate is provided with a reinforcing structure.
[0005] As an optional embodiment of the above technical solution, the reinforcing structure includes a reinforcing ridge, which is disposed on the front side of the supporting plate, and a strip-shaped groove is provided on the back side of the supporting plate corresponding to the position of the reinforcing ridge.

[0021] like Figures 1-3 As shown, this embodiment provides a self-baking electrode phase-to-phase insulation device, including a support column 1, an insulating tube 2, and several insulating fireproof plates 3. The support column 1 is mounted on an insulating platform 5 with a self-baking electrode 4. Figure 3 As shown, the insulating platform 5 is provided with three self-baking electrodes 4, which are arranged at the vertices of an equilateral triangle to achieve uniform heating. The support column 1 is located at the center of the equilateral triangle. The support column 1 can be a supporting steel pipe. The insulating platform 5 has threaded holes, and the bottom end of the support column 1 has external threads. The support column 1 is installed in the threaded holes through its bottom external threads. Three insulating fireproof plates 3 are arranged around the periphery of the insulating pipe 2. Each insulating fireproof plate 3 is positioned between two adjacent self-baking electrodes 4, with an included angle of 60 degrees between adjacent insulating fireproof plates 3. This effectively prevents electrostatic discharge between the self-baking electrodes 4, improving safety during use.
[0022] like Figure 2 As shown, the insulating tube 2 is sleeved on the outside of the support column 1, and the insulating tube 2 is fixed to the support column 1. One end of the insulating fireproof plate 3 is connected to the insulating tube 2 through a connector. The insulating fireproof plate 3 is arranged between two adjacent self-baking electrodes 4 to achieve interphase insulation of the self-baking electrodes 4. After being powered on, the self-baking electrodes 4 will generate static electricity and resistance heat. The insulating fireproof plate 3 has insulation and fireproof functions, and it is not easily carbonized by heat, effectively reducing the risk of fire and improving the safety of the self-baking electrodes 4. Both the insulating fireproof plate 3 and the insulating tube 2 are made of FR-4 epoxy resin material to ensure the fireproof and insulation effects of the insulating fireproof plate 3 and the insulating tube 2. This utility model has a simple structure, is safe and reliable in use, and can ensure the long-term safe and stable operation of the electric furnace.
[0023] Specifically, such as Figure 2As shown, the insulating fireproof board 3 includes a fixed frame 6 and a supporting thin plate 7. The inner side of the fixed frame 6 has a receiving groove adapted to the supporting thin plate 7, and the supporting thin plate 7 is disposed within the receiving groove. The surface of the supporting thin plate 7 has a reinforcing structure. The fixed frame 6 is connected to the insulating tube 2 via a connector. The fixed frame 6 has a certain thickness to ensure the overall strength of the insulating fireproof board 3. The supporting thin plate 7 is disposed within the receiving groove. The thickness of the supporting thin plate 7 is less than the thickness of the fixed frame 6, and the surface of the supporting thin plate 7 has a reinforcing structure to increase its strength. The fixed frame 6 and the supporting thin plate 7 are integrally formed. The structural design of the fixed frame 6 and the supporting thin plate 7 in this invention reduces the overall material usage and weight of the insulating fireproof board 3, facilitating its transportation and installation.
[0024] In one specific embodiment, the reinforcing structure includes reinforcing protrusions 8, which are disposed on the front side of the supporting thin plate 7, and strip-shaped grooves 9 are provided on the back side of the supporting thin plate 7 corresponding to the positions of the reinforcing protrusions 8. Preferably, the front side of the supporting thin plate 7 is provided with multiple reinforcing protrusions 8, which are evenly spaced from top to bottom. Correspondingly, the back side of the supporting thin plate 7 is provided with multiple strip-shaped grooves 9, the positions of which correspond to the positions of the reinforcing protrusions 8, thereby increasing the strength and toughness of the supporting thin plate 7 and reducing its weight. During processing, the insulating fireproof board 3 uses a mold to apply pressure to the supporting thin plate 7, causing the reinforcing protrusions 8 to form on the front side of the supporting thin plate 7, and simultaneously forming the strip-shaped grooves 9 on the back side of the supporting thin plate 7.
[0025] In one specific embodiment, the connector includes a clamp 10 and connecting lugs 11. The clamp 10 is mounted on the insulating tube 2, one end of the connecting lug 11 is connected to the clamp 10, and the other end of the connecting lug 11 is connected to the insulating fireproof board 3. The clamp 10 is fitted onto the insulating tube 2, one end of the connecting lug 11 is fixedly connected to the clamp 10, and the other end of the connecting lug 11 is mounted on the insulating fireproof board 3 by screws. Specifically, two clamps 10 are provided on the insulating tube 2, one upper and one lower, and each clamp 10 has three connecting lugs 11, which are respectively connected to three insulating fireproof boards 3.
[0026] To facilitate the movement of the insulating fireproof board 3, rollers are provided at the bottom of the insulating fireproof board 3, and the rollers are in contact with the insulating platform 5. When it is necessary to inspect and repair the self-baking electrode 4, the clamp 10 can be loosened, and the insulating fireproof board 3 can be moved away from a self-baking electrode 4 using the rollers, so that the worker can inspect and repair the self-baking electrode 4.
