Description

Technical Field

[0001] This utility model relates to the technical field of electric fused brick production equipment, specifically an electric arc furnace with sustainable feeding. Background Technology

[0002] Zirconium corundum fused bricks are solid materials made by melting alumina powder and zircon sand in an electric arc furnace and then casting them. When feeding materials into the electric arc furnace, efforts should be made to feed them evenly in order to improve their melting efficiency. However, current equipment generally uses fixed feeding ports or feeding pipes, which fixes the landing point of the material in the furnace and easily causes material accumulation.

[0003] According to a public notice (Announcement No.: CN219264910U) of a zirconium corundum electric arc furnace feeding device, the above application includes a rotating body, which is vertically inserted into the center of the furnace top. A 90-degree bent feeding channel is opened in the rotating body. After the rotating body is installed on the furnace top, the outlet of the feeding channel is located in the furnace body. A feeding roller that is perpendicular and horizontal to the outlet of the feeding channel is installed.

[0004] However, in actual use, when the rotating body of the above-mentioned feeding device rotates, the discharge port will rotate around the center of the furnace top, thus drawing a circular trajectory in the furnace. If feeding is continuous, a ring of material will accumulate on the circumferential path, resulting in uneven material distribution and affecting melting efficiency. In view of this, we propose an electric arc furnace with continuous feeding. Utility Model Content

Detailed Implementation

[0026] like Figures 1-6 As shown, this utility model provides a technical solution: a continuously feeding electric arc furnace, including a furnace body 1, a control device 2 fixedly connected to the side wall of the furnace body 1, and a feeding assembly 3 provided on the top end face of the furnace body 1. The feeding assembly 3 includes a bearing ring 301, a bearing ring 302, a drive motor 303, a belt 304, a guide ring 305, a hopper 306, a fixed sleeve 307, a movable sleeve 308, a connecting rod 309, a hinge rod 310, a guide rod 311, and a roller 312.

[0027] In one embodiment of this utility model, a bearing ring 301 is fixedly connected to the top end face of the furnace body 1. A bearing ring 302 is provided on the top of the bearing ring 301. The inner wall of the bearing ring 301 is movably connected to a steel ball. The steel ball is movably connected to the bearing ring 302. A feeding hopper 306 is fixedly connected to the top end face of the bearing ring 302. A fixed sleeve 307 is fixedly connected to the bottom of the feeding hopper 306. A movable sleeve 308 is sleeved on the end face of the fixed sleeve 307. The outer diameter of the fixed sleeve 307 is equal to the inner diameter of the movable sleeve 308.

[0028] A rotating shaft is fixedly connected to the output end of the drive motor 303. A pulley is fixedly connected to the side wall of the rotating shaft. The pulley is connected to the belt 304 for transmission. A guide ring 305 is fixedly connected to the top end face of the furnace body 1. The drive motor 303 is fixedly connected to the top end face of the furnace body 1. A pulley is fixedly connected to the side wall of the bearing ring 302. The pulley is connected to the belt 304 for transmission. Through the transmission action of the belt 304, the rotating shaft of the drive motor 303 rotates, driving the bearing ring 302 and the hopper 306 to rotate.

[0029] A connecting frame 4 is fixedly connected to the side wall of the fixed sleeve 307. A rotating shaft 5 is rotatably connected to the end face of the connecting frame 4. The rotating shaft 5 is rotatably connected to the connecting rod 309. The connecting rod 309 is fixedly connected to the outer wall of the movable sleeve 308. The end face of the connecting rod 309 is hinged to the hinge rod 310. A guide rod 311 is hinged to the end of the hinge rod 310 away from the connecting rod 309. A roller 312 is rotatably connected to the end of the guide rod 311 away from the hinge rod 310. The top end face of the guide ring 305 is wavy. The top end face of the guide ring 305 is movably connected to the roller 312, so that while the roller 312 rotates at the top of the guide ring 305, the roller 312 also moves up and down in the longitudinal direction.

[0030] The drive motor 303 starts, causing the hopper 306, fixed sleeve 307, and movable sleeve 308 to rotate, allowing the material to continuously discharge along a circular trajectory. The rotation of the fixed sleeve 307 drives the guide rod 311 and roller 312 to also perform circular motion. Under the guidance of the guide ring 305, the roller 312 rotates and also moves vertically. As the roller 312 rises, it drives the guide rod 311 upward, which in turn pulls the hinge rod 310 and connecting rod 309, causing the movable sleeve 308 to move away from the fixed sleeve 307. This changes the direction of the material outlet clockwise, allowing the material to be thrown to a farther position. Meanwhile, the downward movement of the roller 312 drives the guide rod 311 upward. The downward movement of rod 311 pushes the hinge rod 310 and connecting rod 309, causing the movable sleeve 308 to move closer to the fixed sleeve 307. This causes the material outlet direction to change counterclockwise, allowing the material to be thrown to a closer position. This enables the material to be dynamically and irregularly scattered over a wider area, breaking the problem of material accumulating on the same circumference. It makes the material more evenly distributed in different areas of the furnace, which is conducive to rapid melting, improves feeding efficiency and heat utilization. Through the set roller 312, the movement process is rolling friction, which is much less than sliding friction. The rolling structure is also less prone to jamming at high temperatures, improving the movement response speed and stability, ensuring smooth changes in the discharge direction, protecting the guide structure, and reducing wear.

[0031] In addition, a limiting frame 7 is fixedly connected to the inner wall of the furnace body 1, and a limiting block 6 is slidably connected to the side wall of the limiting frame 7. The limiting block 6 is fixedly connected to the side wall of the guide rod 311. The limiting block 6 and the limiting frame 7 limit the posture of the guide rod 311, so that the axis of the guide rod 311 always remains parallel to the axis of the furnace body 1, maintains the stable movement trajectory of the guide rod 311, constrains its lateral sway or angular deviation, ensures its smooth movement in a fixed direction, prevents deviation or jamming, ensures that the force transmission is a pure axial push-pull action, ensures the accurate force transmission path, improves the efficiency of the mechanism, and makes the entire feeding direction adjustment structure operate more smoothly.

[0032] In this invention, during use, the drive motor 303 starts, causing the hopper 306, fixed sleeve 307, and movable sleeve 308 to rotate, allowing the material to be continuously fed in a circular trajectory. The rotation of the fixed sleeve 307 drives the guide rod 311 and roller 312 to also perform circular motion. Under the guidance of the guide ring 305, the roller 312 rotates while also moving vertically. As the roller 312 rises, it drives the guide rod 311 to move upward, thereby pulling the hinge rod 310 and connecting rod 312. 09, causing the movable sleeve 308 to move away from the fixed sleeve 307, thereby changing the direction of the material outlet clockwise, allowing the material to be thrown to a farther position. Meanwhile, the roller 312 descends, causing the guide rod 311 to move downward, which in turn pushes the hinge rod 310 and the connecting rod 309, causing the movable sleeve 308 to move closer to the fixed sleeve 307, thereby changing the direction of the material outlet counterclockwise, allowing the material to be thrown to a closer position, thus realizing the dynamic and irregular throwing of material in a wider area.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
