Description

Technical Field

[0001] This utility model relates to the field of refining furnace technology, and in particular to an automatic electrode adjustment device for refining furnaces. Background Technology

[0002] A refining furnace is a piece of equipment used in the metallurgical industry to refine molten metal. Its main function is to remove impurities, gases, and non-metallic inclusions from the molten metal, thereby improving the purity and quality of the metal. The refining furnace promotes the flotation and removal of impurities through heating, stirring, blowing, and the addition of alloying elements, while simultaneously adjusting the chemical composition of the metal to meet different specifications and performance requirements. Refining furnaces are widely used in the smelting and casting processes of iron and steel and non-ferrous metals, and are key equipment for improving the performance and quality of metallic materials. Depending on the refining process, refining furnaces can be classified into several types, including electric arc furnaces, induction furnaces, and vacuum furnaces.

[0003] In existing refining furnace technology, electrode heads are typically installed downwards to ensure they can directly insert into the molten pool for reaction during the smelting process. However, this installation method presents inconveniences when the electrode heads require inspection, maintenance, or cleaning. Specifically, when the electrode heads need to be raised to their highest point for manual handling due to wear, contamination, or malfunction, their fixed downward orientation makes it difficult for operators to directly access the lower and sides of the electrode heads, thus limiting the efficiency and effectiveness of inspection, maintenance, or cleaning. This limitation not only increases the workload of operators but may also affect the normal operation and production efficiency of the refining furnace. Utility Model Content

[0004] One objective of this invention is to provide an automatic electrode adjustment device for a refining furnace. This invention addresses the problem mentioned in the background: when the electrode head needs to be raised to its highest position for manual handling due to wear, contamination, or malfunction, its fixed downward orientation makes it difficult for operators to directly access the lower part and sides of the electrode head, thus limiting the efficiency and effectiveness of maintenance or cleaning. This limitation not only increases the labor intensity of operators but may also affect the normal operation and production efficiency of the refining furnace.

[0005] An automatic electrode adjustment device for a refining furnace according to an embodiment of the present invention includes a lateral moving mechanism for realizing the lateral sliding of the main plate, a lifting mechanism for controlling the up and down movement of the lifting block, and a steering mechanism for realizing the steering of the motor body during the lifting process. The lateral moving mechanism includes the main plate and the fixed block, the main plate being movably connected to the surface of the fixed block. The lifting mechanism includes the lifting block, the lifting block being movably connected to the surface of the main plate. The steering mechanism includes a rack and a rotating disk, the rotating disk being rotatably connected to one side surface of the lifting block, a toothed block being fixedly connected to the side surface of the rotating disk, the rack being fixedly connected to the side surface of the main plate, and an electrode body being fixedly connected to the side surface of the rotating disk by a mounting rod.

[0006] Preferably, a first drive motor is fixedly connected to one end of the fixing block, and a lead screw is driven to the output end of the first drive motor. A sliding groove is formed on the upper surface of the fixing block, and the lead screw is rotatably connected inside the sliding groove. The main board is threadedly connected to the surface of the lead screw.

[0007] Preferably, the lower parts of both sides of the motherboard are rotatably connected to limit wheels through a connecting structure, the lower surface of the fixing block is fixedly connected to a slide rail, and the side surface of the limit wheel is provided with a limit groove.

[0008] Preferably, a second drive motor is fixedly connected to the upper part of one side surface of the fixed block via a fixed bracket, and a rotating rod is driven to the output end of the second drive motor.

[0009] Preferably, the lifting block has a sliding groove inside, a second limiting rod is fixedly connected inside the sliding groove, a slider is slidably connected to the surface of the second limiting rod, and the surface of the slider is rotatably connected to one end of the rotating rod.

[0010] Preferably, the motherboard has a lifting groove on its surface, a first limiting rod is fixedly connected inside the lifting groove, and the lifting block is slidably connected to the surface of the first limiting rod.

[0011] Preferably, the side surface of the rotating disk is provided with a slot, the upper part of the side surface of the main board is fixedly connected with an upper locking rod, and the lower part of the side surface of the main board is fixedly connected with a lower locking rod.

[0012] Preferably, a push switch is installed on the lower surface of the upper lever and the upper surface of the lower lever, and an indicator light is installed on the upper surface of the main board. The indicator light is electrically connected to an external power supply through the push switch.

[0013] The beneficial effects of this utility model are:

[0014] This invention, through its steering mechanism, allows the rotating disk to move up and down within the lifting groove on the main board surface via the lifting mechanism. When the electrode body needs to contact the material inside the molten pool with its head facing downwards, the toothed blocks on the side surface of the rotating disk contact and mesh with the rack as it slides downwards. The rack drives the rotating disk to rotate 180 degrees, so that the head of the electrode body contacts the molten pool downwards. When the electrode body is not in use or needs maintenance or cleaning, the lifting mechanism drives the lifting block and the rotating disk to slide upwards inside the lifting groove. As the rotating disk slides upwards, the toothed blocks contact and mesh with the rack, so that the rotating disk rotates 180 degrees when it passes the rack, so that the head of the electrode body faces upwards. This allows the head of the electrode body to be flexibly flipped, facilitating maintenance and cleaning, improving operating efficiency, reducing labor intensity, and ensuring the normal operation and production efficiency of the refining furnace.

[0015] This utility model, through the lifting mechanism, can drive the rotating rod to rotate via the second drive motor, thereby pulling the slider to slide left and right inside the slide groove. Through the coordinated movement between the rotating rod and the slider, the lifting block can reciprocate within the lifting groove, achieving flexible lifting of the electrode body and enhancing the adjustment convenience and operational flexibility of the electrodes in the refining furnace.

[0016] This invention, through its lateral movement mechanism, allows the refining furnace to move laterally left or right when the motor body needs to move laterally. The first drive motor rotates the lead screw, causing the main plate, threaded onto the lead screw surface, to slide left and right within the sliding groove. Simultaneously, as the main plate slides, a connecting structure drives a limiting wheel to roll along the slide rail surface through the limiting groove. This ensures the stability of the main plate and its surface components during left and right sliding, achieving stable left and right movement of the electrode body and improving the accuracy of electrode position adjustment and overall structural stability within the refining furnace.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] refer to Figure 1-4An automatic electrode adjustment device for a refining furnace includes a lateral moving mechanism 1 installed inside a fixed block 13 for lateral sliding of a main plate 19, a lifting mechanism 2 for controlling the up-and-down movement of a lifting block 26, and a steering mechanism 3 for steering the motor body during the lifting process. The lateral moving mechanism 1 includes the fixed block 13 and the main plate 19, with the main plate 19 movably connected to the surface of the fixed block 13. The lifting mechanism 2 includes a lifting block 26, which is movably connected to the surface of the main plate 19. The steering mechanism 3 includes a rack 33 and a rotating disk 31. The rotating disk 31 is rotatably connected to one side surface of the lifting block 26. A toothed block 32 is fixedly connected to the side surface of the rotating disk 31. The rack 33 is fixedly connected to the side surface of the main plate 19. An electrode body 5 is fixedly connected to the side surface of the rotating disk 31 via a mounting rod 4. The rotating disk 31 is driven by the lifting mechanism 2 to move on the surface of the main plate 19. When the electrode body 5 needs to contact the material inside the molten pool with its head facing downwards during the lifting movement within the lifting groove 24, the toothed blocks 32 on the side surface of the rotating disk 31 contact and mesh with the rack 33 as it slides downwards. The rack 33 drives the rotating disk 31 to rotate 180 degrees, so that the head of the electrode body 5 contacts the molten pool with its head facing downwards. When the electrode body 5 is not in use or needs to be inspected, maintained, or cleaned, the lifting mechanism 2 drives the lifting block 26 and the rotating disk 31 to slide upwards inside the lifting groove 24. During the upward sliding of the rotating disk 31, the toothed blocks 32 contact and mesh with the rack 33, so that the rotating disk 31 rotates 180 degrees when it passes the rack 33, so that the head of the electrode body 5 faces upwards. This allows the head of the electrode body 5 to be flexibly flipped, facilitating inspection, maintenance, and cleaning, improving operating efficiency, reducing labor intensity, and ensuring the normal operation and production efficiency of the refining furnace.

[0025] Example 1: A first drive motor 11 is fixedly connected to one end of a fixed block 13. A lead screw 12 is driven to the output end of the first drive motor 11. A sliding groove 14 is provided on the upper surface of the fixed block 13. The lead screw 12 is rotatably connected inside the sliding groove 14. A main plate 19 is threadedly connected to the surface of the lead screw 12. Limiting wheels 17 are rotatably connected to the lower parts of both sides of the main plate 19 through a connecting structure 16. A slide rail 15 is fixedly connected to the lower surface of the fixed block 13. Limiting grooves 18 are provided on the side surfaces of the limiting wheels 17. When the refining furnace is in use, if the motor body needs to move laterally left or right, the first drive motor 11 can drive the lead screw 12 to rotate, so that the main plate 19 threadedly connected to the surface of the lead screw 12 can slide left and right inside the sliding groove 14. At the same time, while the main plate 19 is sliding, the limiting wheels 17 are driven by the connecting structure 16 to roll on the surface of the slide rail 15 through the limiting grooves 18. This ensures the stability of the main plate 19 and its surface structures when sliding left and right, realizing the stable left and right movement of the electrode body 5 and improving the stability of the electrode body 5. To ensure the precision of electrode position adjustment and the stability of the overall structure within the refining furnace, a second drive motor 22 is fixedly connected to the upper part of one side surface of the fixed block 13 via a fixed bracket 21. The output end of the second drive motor 22 is connected to a rotating rod 23. A sliding groove 27 is provided inside the lifting block 26, and a second limiting rod 28 is fixedly connected inside the sliding groove 27. A slider 29 is slidably connected to the surface of the second limiting rod 28, and the surface of the slider 29 is rotatably connected to one end of the rotating rod 23. A lifting groove 24 is provided on the surface of the main board 19, and a first limiting rod 25 is fixedly connected inside the lifting groove 24. The lifting block 26 is slidably connected to the surface of the first limiting rod 25. The second drive motor 22 can drive the rotating rod 23 to rotate, thereby pulling the slider 29 to slide left and right inside the sliding groove 27. Through the coordinated movement between the rotating rod 23 and the slider 29, the lifting block 26 can reciprocate within the lifting groove 24, achieving flexible lifting of the electrode body 5 and enhancing the convenience of electrode adjustment and operational flexibility within the refining furnace.

[0026] Example 2: A slot 34 is provided on the side surface of the rotating disk 31. An upper locking rod 35 is fixedly connected to the upper part of the side surface of the main board 19, and a lower locking rod 36 is fixedly connected to the lower part of the side surface of the main board 19. A push switch 37 is installed on the lower surface of the upper locking rod 35 and the upper surface of the lower locking rod 36. An indicator light 38 is installed on the upper surface of the main board 19. The indicator light 38 is electrically connected to an external power supply through the push switch 37. When the rotating disk 31 moves to the uppermost position, the upper locking rod 35 is locked inside the slot 34. The upper push switch 37 is triggered and controls the indicator light 38 to light up, indicating that the electrode body 5 is at the uppermost position. When the rotating disk 31 moves to the lowermost position, the lower locking rod 36 is locked inside the slot 34. At this time, the lower push switch 37 is triggered and controls another indicator light 38 to light up, indicating that the electrode body 5 is at the lowermost position.

[0027] In use, firstly, the electrode body 5 moves left and right through the lateral movement mechanism 1. Simultaneously, the two sides of the main board 19, through the connecting structure 16, drive the limiting wheels 17 to roll within the limiting grooves 18 of the slide rail 15, ensuring the stability of the overall structure during sliding. Next, the electrode body 5 is raised and lowered through the lifting mechanism 2. This mechanism includes a second drive motor 22, a rotating rod 23, a slider 29, and a lifting block 26. The second drive motor 22 drives the rotating rod 23 to rotate, and the rotating rod 23 pulls the slider 29 to slide left and right within the slide groove 27 of the lifting block 26. Through the coordinated movement of the rotating rod 23 and the slider 29, the lifting block 26 reciprocates within the lifting groove 24 of the main board 19. During the raising and lowering process, the steering mechanism 3 ensures that the head end of the electrode body 5 can be flexibly rotated. When the rotating disk 31 slides up and down within the lifting groove 24... When in motion, the rack 33 drives the rotating disk 31 to rotate 180 degrees, so that the head end of the electrode body 5 faces downward to contact the molten pool or faces upward for easy inspection and maintenance. In addition, the device is also equipped with a position indication function. The side surface of the rotating disk 31 has a slot 34. The upper and lower parts of the side surface of the main board 19 are respectively fixedly connected to the upper locking rod 35 and the lower locking rod 36. A push switch 37 is installed on the locking rod, and an indicator light 38 is installed on the top of the main board 19. When the rotating disk 31 moves to the uppermost or lowermost position, the corresponding locking rod triggers the push switch 37, which controls the indicator light 38 to light up, indicating the position of the electrode body 5. The entire device achieves stable left and right movement, flexible lifting and lowering, and head end flipping of the electrode body 5 through the coordinated work of the lateral movement, lifting and turning mechanism 3, which improves operating efficiency, reduces labor intensity, and ensures the normal operation and production efficiency of the refining furnace.
