Description

Technical Field

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

[0002] Metallurgical furnaces are industrial furnaces that perform heat treatment on various materials or workpieces during metallurgical production. They are widely used in the metallurgical industry, construction, transportation, and other industrial fields. Blast furnaces are used for the reduction and smelting of iron ore, converters use the oxygen content in molten iron to blow and remove impurities, and electric furnaces use electricity to heat scrap steel or ferroalloys for smelting. During smelting, the ore is crushed, and coke and flux are mixed in proportion and continuously charged from the top of the blast furnace.

[0003] At present, 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 material in the hopper is discharged into the spiral feeder, in order to facilitate the mixed material to flow and gather to the bottom, the bottom outlet of the hopper is narrow. Under the action of the accumulation and extrusion of the material, it is easy to cause the feed port to be blocked. Direct stirring after the blockage can loosen the blocked material, but the gaps between the loosened materials are large, which can easily lead to gaps in the area inside the spiral sheet, affecting the stability of the feeding amount. During transportation, the discharge height needs to be adjusted according to the height of the metallurgical furnace. The existing feeding structure generally raises or lowers the feeding structure as a whole when adjusting the height. Due to the heavy weight of the feeding equipment, it is more laborious to adjust it. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference 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.

[0031] 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.

[0032] A connecting support plate 27 is fixedly sleeved on the anti-blocking rod 29 between the conduction head 33 and the feed port 11, and a spring 31 is sleeved on the anti-blocking rod 29 between the connecting support plate 27 and the feed port 11, so that the connecting support plate 27 is more stable when moving. One end of the spring 31 is fixed on the connecting support plate 27, and the other end of the spring 31 is fixed with a sliding pad 32, and the sliding pad 32 is slidingly sleeved with an anti-blocking rod 29. The connecting slide rod 24 and the support sleeve plate 25 are both arranged to be inclined to cooperate with the 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 spring 31, and can move back and forth in the connecting support plate 27, thereby driving the anti-blocking rod 29 to be repeatedly pulled and drawn inside the feed port 11, making it convenient for the corrugated plate 22 to push the moving ball 23 to move stably and repeatedly.

[0033] Several fixed sleeves 35 are fixed at equal distances on the side of the pulley 15, and an inner slide rod 36 is slidably sleeved inside each fixed sleeve 35. A collision ball 34 is fixed on one end of each inner slide rod 36 extending outside the fixed sleeve 35, which is used to intermittently impact the moving ball 23. The vibration force generated by the impact allows the material to fall more tightly inside the spiral feeding tube 1, and after the impact force is transmitted to the bellows telescopic tube 8, the material inside the bellows telescopic tube 8 can quickly fall into the feed port 11, and after the bellows telescopic tube 8 is compressed, some materials will be easily stuck in the compressed gap of the bellows telescopic tube 8, and the vibration force generated by repeated knocking will help the bellows to expand and contract. The material of the tube 8 passes through quickly, further ensuring the smoothness of the material discharge during the feeding process. A spring 2 37 is fixed between the inside of each inner slide bar 36 and the inside of the fixed sleeve 35. Each inner slide bar 36 is configured as a T-shaped rectangular cylinder, so that the inner slide bar 36 can move stably inside the fixed sleeve 35 and will not separate from the fixed sleeve 35. A limiting slide bar 38 is slidably sleeved inside each inner slide bar 36 and the inside of the spring 2 37. The end of the limiting slide bar 38 is fixed inside the fixed sleeve 35. A sliding hole that cooperates with the limiting slide bar 38 is opened inside each inner slide bar 36. When the spring 2 37 is compressed, it can move stably inside the fixed sleeve 35.

[0034] 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.

[0035] 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 spiral rotating rod inside the spiral feeding tube 1 extends to one end of the outer side of the spiral feeding tube 1 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.

[0036] 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 discharge box 15. The connecting rod 17 extends to one end of the auxiliary discharge box 15 and is fixed with a rectangular rod. The separator assembly 16 is slidably sleeved on the rectangular rod, and a rectangular groove that cooperates with the rectangular rod is opened inside the separator assembly 16. The other end of the separator assembly 16 is rotatably sleeved with a cylinder, and the end of the cylinder is fixed to the inner wall of the sealing cover 20. A threaded tube that cooperates with the sealing cover 20 is fixed to the side end of the auxiliary discharge box 15, which is convenient for fixing and disassembling the sealing cover 20 and the auxiliary discharge box 15. At the same time, the hollow design makes it convenient to remove the separator assembly 16 inside the auxiliary discharge box 15, making the feeding structure more convenient and labor-saving during maintenance.

[0037] Working principle: When feeding, first move the spiral feeding tube 1 to the side of the metallurgical furnace through the mobile bracket 2, turn on the mobile unit, drive the connecting bracket 14 to move, and when the connecting bracket 14 moves, it drives the driving roller 12 to move through the connecting plate 13. The driving roller 12 mobile device drives the spiral feeding tube 1 to rotate. When the spiral feeding tube 1 rotates, it drives the adjusting shaft 9 to rotate inside the fixed bracket 10 and stretches or compresses the corrugated telescopic tube 8 until the auxiliary discharge box 15 is aligned with the feed of the metallurgical furnace, and the material is poured into the silo 3. Turn on the drive motor 4, and the drive motor 4 drives the pulley 5 and the heat-resistant The belt 6 drives the spiral feeding pipe 1 to run and transport the material to the inside of the discharge port 7. When the pulley 15 rotates, it drives the auxiliary turntable 21 to rotate, and the auxiliary turntable 21 drives the corrugated plate 22 to rotate. The corrugated plate 22 rotates intermittently to push the moving ball 23, so that the moving ball 23 drives the connecting slide 24 to move inside the support sleeve 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 feed port 11, so that the material inside the feed port 11 is loosened, and the corrugated plate 22 is recessed on the side of the moving ball 23, and the thrust on the moving ball 23 is released. When the material is pulled out of the feeding port 11, the anti-blocking rod 29 is used to pull the material out of the feeding port 11, and the anti-blocking rod 29 is used to pull the material out of the feeding port 11. The material is pulled out of the feeding port 11, and the anti-blocking rod 29 is used to pull the material out of the feeding port 11. The anti-blocking rod 29 is used to pull the material out of the feeding port 11, and the anti-blocking rod 29 is used to pull the material out of the feeding port 11. The anti-blocking rod 29 is used to pull the material out of the feeding port 11, and the anti-blocking rod 29 is used to pull the material out of the feeding port 11. The material on the side is blocked. While avoiding blockage, the fullness of the feeding is guaranteed. After the material enters the auxiliary discharge box 15 through the discharge port 7, the spiral feeding tube 1 runs through the pulley 2 19 and the other heat-resistant belt 6 to drive the connecting rod 17 to rotate, and the connecting rod 17 drives the separator assembly 16 to rotate. The separator assembly 16 rotates to push the material. When cleaning, screw the sealing cover 20 to drive the cylinder to move out of the separator assembly 16, and then remove the separator assembly 16 for cleaning. After cleaning, put the rectangular groove of the separator assembly 16 on the rectangular rod, and screw the sealing cover 20 to the auxiliary discharge box 15 for fixing.
