[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Referring to Figure 1 , Figure 2 , Figure 4 , an embodiment provided by the present invention: an electrofused magnesia smelting device, including a base 1. A fixed block 9 is fixedly connected to the top of the base 1, enabling the base 1 to provide a supporting and fixing effect for the fixed block 9. The top of the fixed block 9 is arc-shaped. A frame 3 is fixedly connected to the top of the base 1, enabling the base 1 to provide a supporting and fixing effect for the frame 3. The middle of the frame 3 is hollow. A servo motor 5 is fixedly connected to the outer wall of the frame 3, enabling the frame 3 to provide a supporting and fixing effect for the servo motor 5. The servo motor 5 is a general motor. The output shaft of the servo motor 5 is fixedly connected to an electric arc furnace 2, enabling the output shaft of the servo motor 5 to drive the electric arc furnace 2 to rotate. The servo motor 5 provides a supporting effect for the electric arc furnace 2. A stirrer 11 is rotatably connected to the inner wall of the electric arc furnace 2, enabling the electric arc furnace 2 to provide a supporting effect for the stirrer 11. The stirrer 11 can rotate along the inner wall of the electric arc furnace 2 for stirring the electrofused magnesia raw materials to make them heat more evenly. One end of the stirrer 11 is fixedly connected to a gear A8, enabling the gear A8 to drive the stirrer 11 to rotate when it rotates, and the other end of the stirring rod 11 does not contact the scraper 12.

[0034] Referring to Figure 1 , Figure 2 , Figure 5 , a scraper 12 is rotatably connected to the inner wall of the electric arc furnace 2, enabling the electric arc furnace 2 to provide a supporting effect for the scraper 12. The scraper 12 rotates on the inner wall of the electric arc furnace 2 for scraping residues and sediments. One end of the scraper 12 is fixedly connected to a gear D18, enabling the gear D18 to drive the scraper 12 to rotate when it rotates. A transmission mechanism is arranged on the top of the base 1. The transmission mechanism includes a stepping motor 4. The stepping motor 4 is a special motor, and its output shaft will not self-lock. The output shaft of the stepping motor 4 is drivingly connected to a gear B14. The output shaft of the stepping motor 4 drives the gear B14 to rotate through a chain and sprocket. The outer wall of the gear B14 meshes with the outer wall of the gear A8. When the electric arc furnace 2 is in a standing state, the gear B14 drives the gear A8 to rotate. When the electric arc furnace 2 rotates to pour out the molten electrofused magnesia after smelting is completed, the gear B14 disengages from the gear A8 and no longer meshes. At this time, the stirrer 11 no longer rotates and stirs.

[0035] Referring to Figure 2 , Figure 4 , Figure 6, a rotating column 13 is fixedly connected to the output shaft of the stepping motor 4, so that the output shaft of the stepping motor 4 drives the rotating column 13 to rotate. The rotating column 13 is drivingly connected to a gear C17, and the rotating column 13 drives the gear C17 to rotate through a chain and sprocket. The outer wall of the gear C17 meshes with the outer wall of the gear D18. When the electric arc furnace 2 rotates 90 degrees and is fixed to pour out the molten fused magnesia, the gear C17 meshes with the gear D18, and the gear C17 drives the gear D18 to rotate. When the electric arc furnace 2 returns to the standing state, the gear C17 and the gear D18 disengage and no longer mesh. At this time, the scraper 12 no longer rotates and scrapes. A cylinder 16 is fixedly connected to the outer wall of the electric arc furnace 2, so that the cylinder 16 provides a supporting effect for the electric arc furnace 2. One end of the cylinder 16 is rotatably connected to a support column 15, so that the cylinder 16 can rotate inside the inner wall of the support column 15. The support column 15 provides a supporting effect for the cylinder 16. The inner wall of the support column 15 is rotatably connected to one end of the gear C17, so that one end of the gear C17 can rotate inside the inner wall of the support column 15. The support column 15 provides a supporting effect for the gear C17. The outer wall of the support column 15 is rotatably connected to one end of the rotating column 13, so that the support column 15 provides a supporting effect for the rotating column 13. A fixed column 19 is fixedly connected to the outer wall of the support column 15, so that the support column 15 provides a supporting and fixing effect for the fixed column 19. One end of the fixed column 19 is slidably connected to the inner wall of the electric arc furnace 2. An arc-shaped notch is formed on the back of the electric arc furnace 2. One end of the fixed column 19 can enter and exit the arc-shaped notch, and can fix it after the electric arc furnace 2 rotates 90 degrees. A sealing ring 20 is fixedly connected to the outer wall of the electric arc furnace 2, so that the sealing ring 20 can seal the connection between the stirrer 11 and the scraper 12 and the electric arc furnace 2 to prevent the molten fused magnesia from overflowing. There are two groups of sealing rings 20. An outlet is provided on the outer wall of the electric arc furnace 2, which can be used to pour out the molten fused magnesia after melting is completed.

[0036] Refer to Figure 1 - Figure 3, the top of the base 1 is fixedly connected to the outer wall of the stepper motor 4, enabling the base 1 to provide a support and fixation effect for the stepper motor 4. The top of the base 1 is fixedly connected to the bottom of the support column 15, enabling the base 1 to provide a support and fixation effect for the support column 15, ensuring the stability of the support column 15. The top of the base 1 is fixedly connected to a bracket 10, enabling the base 1 to provide a support and fixation effect for the bracket 10. The middle part of the bracket 10 is hollowed out, and the inner wall of the bracket 10 is rotatably connected to the outer wall of gear B 14, enabling the outer wall of gear B 14 to rotate within the inner wall of the bracket 10. The bracket 10 provides a support effect for gear B 14. The top of the electric arc furnace 2 penetrates and is fixedly connected to a feed pipe 6, enabling the electric arc furnace 2 to provide a fixation effect for the feed pipe 6. The electrofused magnesia raw material can be added from the feed pipe 6. The top of the electric arc furnace 2 penetrates and is fixedly connected to an electrode pipe 7, and the electrode pipe 7 can heat and melt the electrofused magnesia raw material inside the electric arc furnace 2. The outer wall of the electric arc furnace 2 is in contact with the outer wall of the fixed block 9, enabling the electric arc furnace 2 to remain stable when in a standing state. The inner wall of the fixed block 9 is rotatably connected to the outer wall of the rotating column 13, enabling the rotating column 13 to rotate along the inner wall of the fixed block 9 and remain stable without deviation.

[0037] Working principle: The staff adds raw materials from the feed pipe 6, and the electric arc furnace starts heating through the electrode pipe 7. At this time, the stepper motor 4 is started, and it drives gear B 14 to rotate through a chain and sprocket. Gear B 14 drives gear A 8 to rotate, and at the same time, gear A 8 drives the stirrer 11 to rotate to stir the raw materials, making them evenly heated and accelerating the melting speed of the raw materials.

[0038] When the melting is completed, the servo motor 5 is started to drive the electric arc furnace 2 to rotate. During the rotation of the electric arc furnace 2, it will drive gear A 8 to disengage from gear B 14 and no longer mesh. At this time, the stirrer 11 stops working. When the electric arc furnace 2 rotates 90 degrees, it is fixed by being clamped with the fixed column 19 through the arc-shaped notch on the back. At this time, gear C 17 meshes with gear D 18. The output shaft of the stepper motor 4 drives the rotating column 13 to rotate, and the rotating column 13 drives gear C 17 to rotate within the inner wall of the support column 15 through a chain and sprocket. Gear C 17 drives gear D 18 to rotate, and at the same time drives the scraper 12 fixed on gear D 18 to rotate, scraping off the remaining residues and precipitates to avoid the formation of more lumps over time, which may affect the subsequent use of the electric arc furnace 2.

[0039] When the electric arc furnace 2 is in the standing state, the gear A8 meshes with the gear B14 through the transmission mechanism to drive the stirrer 11 to work. At this time, the gear C17 and the gear D18 are not in contact, and the scraper 12 does not work. When the melting is completed and the electric arc furnace 2 rotates to prepare for pouring, the gear A8 and the gear B14 are disengaged, and the stirrer 11 stops working. At this time, the gear C17 and the gear D18 mesh to drive the scraper 12 to scrape. The transmission mechanism can be used for stirring during the melting of fused magnesia. When the melting is completed and pouring is required, the remaining residue can be automatically scraped. Only one stepping motor 4 can make the two groups of structures work when needed, saving costs.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
