Description

Technical Field

[0001] The present invention relates to the technical field of feeding structures, and specifically to a feeding structure for a metallurgical furnace. Background Art

[0002] A metallurgical furnace is an industrial furnace for hot processing various materials or workpieces during the metallurgical production process, and is widely used in the metallurgical industry, construction industry, transportation industry, and other industrial fields. Among them, blast furnaces are used for the reduction smelting of iron ore, converters use the oxygen content in molten iron for blowing to remove impurities, and electric furnaces use electric energy to heat scrap steel or ferroalloys for smelting. During smelting, ores need to be crushed, and coke and fluxes are continuously loaded from the top of the blast furnace after being mixed in proportion.

[0003] Currently, the crushed and mixed ore raw materials are transported to the top of the blast furnace through a screw conveyor. During the feeding process, when the materials in the silo are discharged into the internal part of the screw feeder, in order to facilitate the flow and aggregation of the mixed materials to the bottom, the outlet at the bottom of the silo is relatively narrow. Under the action of the accumulation and extrusion of the materials, it is easy to cause blockage at the feeding port. After the blockage, directly agitating can loosen the blocked materials, but the gaps between the loosened materials are relatively large, which easily leads to the appearance of gaps in the area inside the screw blades, affecting the stability of the feeding volume. During transportation, it is necessary to adjust the discharging height according to the height of the metallurgical furnace. For the existing feeding structure, when adjusting the height, generally the entire feeding structure is lifted or lowered. Due to the large weight of the feeding equipment, it is relatively laborious to adjust. Summary of the Invention

Detailed implementation manners

[0018] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Refer to Figures 1-9, a feeding structure for a metallurgical furnace, comprising a spiral feeding tube 1 and a mobile bracket 2, the spiral feeding tube 1 rotating frame is mounted on the mobile bracket 2, a driving motor 4 is installed on the spiral feeding tube 1 on the side of the feeding port 11, the output end of the driving motor 4 and the end of the spiral rotating rod inside the spiral feeding tube 1 extending to the outside are fixed with a pulley 5, the two pulleys 5 are connected by a heat-resistant belt 6, the top of the feeding end of the spiral feeding tube 1 is fixed with a feeding port 11, the bottom of the discharging end is fixed with a discharge port 7, the top of the feeding port 11 is connected with a silo 3, the silo 3 is a cone with a downward pointed end, which is convenient for the material to be fed into the silo The material flows inside the feed port 11, and it is also convenient to pour the mixed material through the wide-mouthed top of the silo 3. An anti-blocking rod 29 is inserted into the feed port 11 for intermittent reciprocating sliding. The anti-blocking rod 29 extends to the inside of the feed port 11 and is evenly fixed with several movable plates 30. When the anti-blocking rod 29 is repeatedly moved and pulled inside the feed port 11, the crushed mining materials inside the feed port 11 are pushed to loosen, so as to prevent the ore materials from being squeezed and blocked inside the feed port 11. A conductive head 33 is fixed at one end of the anti-blocking rod 29 extending to the outside of the feed port 11, and several collision balls 34 are evenly arranged at the bottom of the conductive head 33.

[0020] An auxiliary turntable 21 is fixed to the outside of the pulley 15, and a corrugated plate 22 with a corrugated end edge is fixed to the side of the auxiliary turntable 21. A number of moving balls 23 are equidistantly arranged on the side of the corrugated plate 22. When the corrugated plate 22 rotates, according to the different spacing between its corrugations and the moving balls 23, when the corrugated plate 22 rotates to the crest and contacts the moving balls 23, the moving balls 23 are pushed to move toward the feed port 11. The moving balls 23 are slidably arranged on the side of the corrugated plate 22. A connecting slide rod 24 is fixed to the side of the moving ball 23. A supporting sleeve 25 is slidably sleeved on the connecting slide rod 24 to support the connecting slide rod 24. A fixed support rod 28 is symmetrically fixed to the side of the bottom of the support sleeve 25, and the other end of the fixed support rod 28 is fixed to the side wall of the feed port 11. A push plate 26 is fixed to the side of the connecting slide rod 24, and the side of the push plate 26 is slidably fitted with a connecting support plate 27. After the corrugated plate 22 pushes the moving ball 23 to move, the push plate 26 moves along the inclination direction of the spiral feeding tube 1. The horizontal distance generated during the movement is the distance that the push plate 26 pushes the connecting support plate 27 to move. The connecting support plate 27 is slidably sleeved on the fixed support rod 28, and the fixed support rod 28 supports and limits the connecting support plate 27 to ensure the stability of the connecting support plate 27 during movement.

[0021] A connecting support plate 27 is fixedly sleeved on the anti-blocking plug rod 29 between the conduction head 33 and the feed inlet 11. A first spring 31 is sleeved on the anti-blocking plug rod 29 between the connecting support plate 27 and the feed inlet 11, so that the connecting support plate 27 moves more stably. One end of the first spring 31 is fixed on the connecting support plate 27, and a sliding backing plate 32 is fixed at the other end of the first spring 31. The sliding backing plate 32 is slidably sleeved on the anti-blocking plug rod 29. Both the connecting slide rod 24 and the support sleeve plate 25 are arranged in an inclined shape to cooperate with the first pulley 5. When the corrugated plate 22 rotates, the moving ball 23 in the same direction as the corrugated plate 22 is pushed by the corrugated plate 22 and the first spring 31, and can reciprocate in the connecting support plate 27, thereby driving the anti-blocking plug rod 29 to be repeatedly pulled in and out inside the feed inlet 11, facilitating the corrugated plate 22 to push the moving ball 23 to move stably and repeatedly.

[0022] A number of fixed sleeves 35 are fixedly arranged at equal intervals on the side of the first pulley 5. An inner slide rod 36 is slidably sleeved inside each fixed sleeve 35. A collision ball 34 is fixed at one end of each inner slide rod 36 extending outside the fixed sleeve 35, which is used to intermittently impact the moving ball 23. Through the vibration force generated by the impact, the material can fall on the spiral feeding pipe 1 more tightly. After the impact force is transmitted to the corrugated expansion pipe 8, the material inside the corrugated expansion pipe 8 can quickly fall into the feed inlet 11. And after the corrugated expansion pipe 8 is compressed, some materials are likely to get stuck in the compressed gap of the corrugated expansion pipe 8. The vibration force generated by repeated knocking helps the material in the corrugated expansion pipe 8 to pass quickly, further ensuring the smoothness of feeding during the feeding process. A second spring 37 is fixed between the inside of each inner slide rod 36 and the inside of the fixed sleeve 35. Each inner slide rod 36 is arranged as a T-shaped rectangular column, so that the inner slide rod 36 can move stably inside the fixed sleeve 35 and will not separate from the fixed sleeve 35. A limit slide rod 38 is slidably sleeved inside each inner slide rod 36 and inside the second spring 37. The end of the limit slide rod 38 is fixed inside the fixed sleeve 35. A slide hole cooperating with the limit slide rod 38 is opened inside each inner slide rod 36, and it can move stably inside the fixed sleeve 35 when the second spring 37 is compressed.

[0023] A bellows telescopic tube 8 is fixed between the feed port 11 and the silo 3. When the angle of the spiral feeding tube 1 is adjusted, the spiral feeding tube 1 rotates to drive the feed port 11 to squeeze or stretch the bellows telescopic tube 8, thereby meeting the rotation requirement of the spiral feeding tube 1 and facilitating the angle adjustment of the spiral feeding tube 1. Adjustment shafts 9 are fixed on both sides of the feed port 11. The two adjustment shafts 9 are rotatably connected to the inside of the fixed frame 10. The fixed frame 10 is fixed on the movable bracket 2. The spiral feeding tube 1 is symmetrically rotatably sleeved with drive rollers 12. Both ends of the two drive rollers 12 are rotatably connected to the connecting plate 13. A movable connecting bracket 14 is fixed to the bottom of the connecting plate 13. The bottom of the connecting bracket 14 is driven to reciprocate by a moving unit. The moving unit is specifically a slide rail, a screw rod rotatably connected to the inside of the slide rail, and a screw rod for driving the screw rod and fixed. The servo motor installed on one side of the slide rail and the movable sleeve block threaded on the screw rod are fixed to the bottom of the connecting bracket 14. When the angle of the spiral feeding tube 1 needs to be adjusted, the servo motor drives the screw rod to rotate. When the screw rod rotates, the movable sleeve block is driven to move under the action of the thread, thereby driving the connecting bracket 14 to move, thereby pushing the spiral feeding tube 1 to rotate and adjust the feeding height. The middle part of each driving roller 12 is set to a depression that cooperates with the spiral feeding tube 1 to limit the spiral feeding tube 1 so that the spiral feeding tube 1 can be stably supported and limited. The top of the connecting bracket 14 is set to a U-shape that cooperates with the connecting plate 13 and the driving roller 12. Moving rollers are symmetrically fixed to the bottom of the connecting bracket 14. The moving rollers are located on both sides of the moving unit for supporting the connecting bracket 14.

[0024] An auxiliary discharge box 15 is fixed to the bottom of the discharge port 7 by bolts, and the top of the auxiliary discharge box 15 is a hollow cylinder. A detachable separator assembly 16 is rotatably connected inside the auxiliary discharge box 15, and the separator assembly 16 consists of a rotating rod and separators equidistantly arranged and fixed on the outer surface of the rotating rod. Therefore, when the separator assembly 16 rotates until the two separator discharge ports are aligned, the material between the two separators is discharged, and a connecting rod 17 is rotatably sleeved inside the discharge port 7. The other end of the spiral rotating rod inside the spiral feeding tube 1 extends to the outside and is fixed with a pulley 2 19 on the side end of the connecting rod 17. The two pulleys 2 19 are connected by another heat-resistant belt 6 for transmission. A support plate 18 is rotatably sleeved on the connecting rod 17, and the support plate 18 is fixed on the outer surface of the spiral feeding tube 1, so that the spiral feeding tube 1 drives the separator assembly 16 to rotate when it is running, and the material is quickly discharged, which facilitates the dispersed discharge of the material.

[0025] One end of the separator assembly 16 is slidably sleeved on the outer wall of the connecting rod 17, and the other end of the separator assembly 16 is rotatably sleeved on the inner wall of the sealing cover 20. The sealing cover 20 is threadedly sleeved on the side end of the auxiliary discharging box 15. One end of the connecting rod 17 extending into the auxiliary discharging box 15 is fixed with a rectangular rod. The separator assembly 16 is slidably sleeved on the rectangular rod, and a rectangular groove matching with the rectangular rod is formed inside the separator assembly 16. A cylinder is rotatably sleeved on the other end of the separator assembly 16, and the end of the cylinder is fixed on the inner wall of the sealing cover 20. A threaded pipe matching with the sealing cover 20 is fixed on the side end of the auxiliary discharging box 15, which is convenient for the fixing and disassembly of the sealing cover 20 and the auxiliary discharging box 15. At the same time, the hollow design is convenient for taking out the separator assembly 16 inside the auxiliary discharging box 15, making the feeding structure more convenient and labor-saving during maintenance.

[0026] Working principle: During feeding, first move the spiral feeding pipe 1 to the side of the metallurgical furnace through the moving support 2. Open the moving unit to drive the connecting support 14 to move. When the connecting support 14 moves, it drives the driving roller 12 to move through the connecting plate 13. The driving roller 12 moves the device to drive the spiral feeding pipe 1 to rotate. When the spiral feeding pipe 1 rotates, it drives the adjusting rotating shaft 9 to rotate inside the fixed bracket 10 and stretches or compresses the corrugated telescopic pipe 8 until the auxiliary discharge box 15 is aligned with the feeding place of the metallurgical furnace. Pour the material into the inside of the storage bin 3. Open the driving motor 4. The driving motor 4 drives the spiral feeding pipe 1 to operate through the first pulley 5 and the heat-resistant belt 6, and conveys the material to the inside of the discharge port 7. When the first pulley 5 rotates, it drives the auxiliary turntable 21 to rotate. The auxiliary turntable 21 drives the corrugated plate 22 to rotate. The corrugated plate 22 intermittently pushes the moving ball 23 during rotation, so that the moving ball 23 drives the connecting slide rod 24 to move inside the supporting sleeve plate 25, and pushes the connecting support plate 27 through the push plate 26. After the connecting support plate 27 is pushed, it drives the anti-blocking plug rod 29 to slide inside the feeding port 11, so that the material inside the feeding port 11 is loosened. When the depression of the corrugated plate 22 is located on the side of the moving ball 23 and the thrust on the moving ball 23 is released, the collision ball 34 rotates to the side of the conduction head 33 and impacts the conduction head 33. Under the action of the impact force, it drives the inner slide rod 36 to compress the second spring 37 and move into the fixed sleeve 35. The vibration generated by the impact force acts on the material inside the feeding port 11 through the anti-blocking plug rod 29, so that the material can fall and fill the gap generated by the loosening of the material after the insertion and extraction. First, the anti-blocking plug rod 29 inserts and extracts the movable material, and then the vibration generated by the collision ball 34 shakes down the upper material, which is timely supplemented into the gap generated after the anti-blocking plug rod 29 is pulled out and flows into the inside of the spiral feeding pipe 1, and also avoids the blockage of the material above the anti-blocking plug rod 29. While avoiding blockage, it ensures the fullness of feeding. After the material enters the inside of the auxiliary discharge box 15 through the discharge port 7, the spiral feeding pipe 1 operates to drive the connecting rod 17 to rotate through the second pulley 19 and another heat-resistant belt 6. The connecting rod 17 drives the partition plate assembly 16 to rotate. The partition plate assembly 16 rotates to push and distribute the material. During cleaning, turn the sealing cover 20 to drive the cylinder to move out of the partition plate assembly 16, and then remove the partition plate assembly 16 for cleaning. After cleaning, put the rectangular groove of the partition plate assembly 16 on the rectangular rod, and turn the sealing cover 20 to fix it on the auxiliary discharge box 15.
