Description

Technical Field

[0001] This invention relates to the field of steel processing technology, specifically to a scrap steel refining furnace device with automatic slag removal function. Background Technology

[0002] In the steel industry, scrap steel is an important renewable resource. Its refining process is a key link to realize the recycling of steel, reduce production costs and carbon emissions. As the core equipment for scrap steel refining, the steelmaking furnace is prone to metal oxides, slag and unreacted impurities adhering to the furnace wall surface during high-temperature smelting operations, forming a hard residual slag layer. When traditional equipment cleans the inside of a steelmaking furnace, the residual heat from the slag adhering to the furnace wall causes the cleaning blades to soften and deform during use, affecting their sharpness. Furthermore, the hard slag adhering to the furnace interior, combined with the residual heat, causes significant wear on the blades during use, reducing their service life. Summary of the Invention

[0003] To address the technical problems encountered in existing steelmaking furnace cleaning processes, where residual heat from slag adhering to the furnace's inner wall causes the cleaning blades to soften and deform during use, affecting their sharpness, and the hardness of the slag adhering to the furnace, combined with the residual heat, leads to significant wear on the blades and reduces their service life, this invention provides a scrap steel refining furnace device with automatic slag removal function.

[0004] The technical solutions provided by the embodiments of the present invention are as follows: This invention provides a scrap steel refining furnace device with automatic slag removal function, including a steelmaking furnace. A baffle that slides vertically along a first sliding groove is slidably mounted on the outside of the steelmaking furnace. A movable rod is rotatably mounted on one side of the steelmaking furnace. One end of the movable rod is connected to a support plate. A sliding seat is slidably mounted on the outside of the support plate. A threaded rod is rotatably mounted inside the sliding seat. One end of the threaded rod is connected to a rotating disk. One end of the rotating disk is connected to a pressure knife. The other end of the rotating disk is connected to an inclined block A. A pressure plate slides on the outer side of the threaded rod. Multiple sets of third sliding grooves for sliding the pressure plate are opened on the outer side of the threaded rod. An inclined block B is installed on one end of the pressure plate near the rotating disk. One side of the inclined block B is an inclined surface. The pressure plate is equipped with multiple sets of first nozzles. One end of each set of first nozzles is connected to two sets of connecting valves. Each set of connecting valves is equipped with a shut-off valve. The other end of each set of connecting valves is connected to a water supply device.

[0005] The lower end of the support plate is provided with a fourth sliding groove, which is slidably connected to the movable buckle. A hydraulic cylinder is installed on one side of the steelmaking furnace, and the output end of the hydraulic cylinder is rotatably connected to the fourth sliding groove.

[0006] The support plate has a second sliding groove at one end, the slide block is slidably connected to the second sliding groove, a reduction motor is installed at one end of the slide block, and one end of the threaded rod passes through the baffle and is connected to the output end of the reduction motor.

[0007] A horizontal plate is installed inside the rotating disk. The outer diameter of the rotating disk matches the inner diameter of the steelmaking furnace. The other end of the threaded rod passes through the movable rod and is connected to the pressure plate and the horizontal plate. The threaded rod is threadedly connected to the movable rod.

[0008] One side of the inclined block A is an inclined surface. The inclined block A and the inclined block B are located on the same plane. As the inclined block A rotates with the rotating disk, the inclined surface of the inclined block A intermittently squeezes the inclined block B. Multiple sets of force transmission blocks are installed on the end of the pressure plate near the rotating disk.

[0009] The pressure plate is internally connected to a bearing, which is slidably connected to multiple sets of third sliding grooves.

[0010] The horizontal plate is rotatably connected to a movable ring at one end near the pressure plate. One end of the movable ring is connected to a rack, and the other end of the rack extends through the pressure plate to the other end of the pressure plate.

[0011] Each of the multiple sets of first nozzles has a connecting pipe A fixedly connected to one end. The other end of the multiple sets of connecting pipe A is connected to two sets of connecting valves. Each of the two sets of connecting valves has a connecting pipe B connected to one end. The other end of the connecting pipe B is connected to the water supply equipment. Each of the two sets of connecting valves has a branch end connected to two sets of second nozzles. The four sets of second nozzles are installed inside the pressure plate and face the pressure knife side.

[0012] One end of the shut-off valve is fixedly connected to a valve stem, and the other end of the valve stem extends through the connecting valve to the outside. A gear is connected to the end of the valve stem located on the outside of the connecting valve, and the gear meshes with a rack.

[0013] Both sets of connecting valves have a fixed connecting pipe C at their branch ends, and the other end of each set of connecting pipe C is connected to the two sets of second nozzles.

[0014] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: In this embodiment of the invention, the downward vibration force of the pressure plate assists the pressure knife in more easily removing slag from the inner wall of the steelmaking furnace, preventing the problems of slag adhesion or difficulty in cleaning caused by simple squeezing. This makes slag removal smoother and more thorough. Simultaneously, the solid design of the pressure plate ensures sufficient vibration force is applied to the rotating disc, making the slag removal process easier. Furthermore, it prevents slag from splashing outwards during squeezing, preventing injury to operators or damage to equipment, significantly improving workplace safety. The irregular cold water splashing formed by the water source causes the slag on the inner wall to quickly break up and fall off due to thermal expansion and contraction. This reduces the resistance during subsequent cleaning of the inner wall by the pressure knife, lowering the mechanical wear and load on the pressure knife. At the same time, the cold water splashing promotes the assisted slag removal, reducing direct wear of the pressure knife on the inner wall of the steelmaking furnace and indirectly extending the furnace's service life. Water is sprayed directionally onto the edge of the pressure cutter at regular intervals, thereby promptly removing the heat generated by the rotational friction of the pressure cutter. This prevents the pressure cutter from wearing or deforming due to high temperatures, ensuring the stable process of the pressure cutter descending along the inner wall of the steelmaking furnace to clean the residue. At the same time, the water sprayed onto the pressure cutter will further contact the inner wall of the steelmaking furnace and descend along the inner wall, continuously utilizing the thermal expansion and contraction effect to act on the residue on the inner wall. In conjunction with localized splashing, this more comprehensively promotes the fragmentation and detachment of the residue. Attached Figure Description

[0025] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0026] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0027] Reference Figures 1-9 The present invention provides a scrap steel refining furnace device with automatic slag removal function, including a steelmaking furnace 1, a baffle 3 that slides vertically along a first sliding groove 2 on the outside of the steelmaking furnace 1, a movable rod 4 that rotates on one side of the steelmaking furnace 1, a support plate 6 that is connected to one end of the movable rod 4, a sliding seat 8 that slides on the outside of the support plate 6, a threaded rod 5 that rotates inside the sliding seat 8, a rotating disk 10 that is connected to one end of the threaded rod 5, a pressure knife 11 that is connected to one end of the rotating disk 10, and an inclined block A12 that is connected to the other end of the rotating disk 10. A pressure plate 17 slides on the outside of the threaded rod 5. Multiple sets of third slide grooves 15 for sliding of the pressure plate 17 are opened on the outside of the threaded rod 5. An inclined block B18 is installed on one end of the pressure plate 17 near the rotating disk 10. One side of the inclined block B18 is an inclined surface. The pressure plate 17 has multiple sets of first nozzles 20 installed inside. One end of each set of first nozzles 20 is connected to two sets of connecting valves 22. Each set of connecting valves 22 has a shut-off valve installed inside. The other end of each set of connecting valves 22 is connected to a water supply device.

[0028] In an optional embodiment, a fourth sliding groove 29 is provided at the lower end of the support plate 6. The fourth sliding groove 29 is slidably connected to the movable buckle 30. A hydraulic cylinder 28 is installed on one side of the steelmaking furnace 1. The output end of the hydraulic cylinder 28 is rotatably connected to the fourth sliding groove 29. The operator can control the lifting height or position of the baffle 3 according to the actual situation. When the baffle 3 is raised, when the steelmaking furnace 1 is melting scrap steel, the baffle 3 will increase the height of the feed inlet of the steelmaking furnace 1. And the initial position of the pressure plate 17 is located in the steelmaking furnace. On one side, when the preheated scrap steel enters the steelmaking furnace 1, the baffle 3 and the pressure plate 17 guide the scrap steel. After the scrap steel enters the steelmaking furnace 1, the baffle 3 and the pressure plate 17 increase the height of the feed inlet of the steelmaking furnace 1. Therefore, with the cooperation of the baffle 3 and the pressure plate 17, the splashing molten iron and steel slag will be effectively intercepted, thereby protecting the safety of the construction site. When pouring out the molten iron, the baffle 3 can guide the flow of the molten iron, thereby preventing the molten iron from adhering to the outer surface of the steelmaking furnace 1. When the operator uses the device, the hydraulic cylinder 28 pushes the movable buckle 30 to rise. When the movable buckle 30 rises, it will simultaneously push the support plate 6 to flip. When the support plate 6 flips, the movable buckle 30 will slide inside the fourth slide groove 29 due to the flipping of the support plate 6.

[0029] In an optional embodiment, a second groove 7 is provided at one end of the support plate 6, and a slide block 8 is slidably connected to the second groove 7. A reduction motor 9 is installed at one end of the slide block 8, and one end of the threaded rod 5 passes through the baffle 3 and is connected to the output end of the reduction motor 9. As mentioned above, since the support plate 6 is connected to the movable rod 4, when the support plate 6 flips, it will synchronously drive the movable rod 4 to flip synchronously. After the movable rod 4 flips, the threaded rod 5 is aligned with the central axis of the steelmaking furnace 1. At this time, the reduction motor 9 is started, and after the reduction motor 9 starts, it will drive the threaded rod 5 to rotate. When the threaded rod 5 rotates, since the threaded rod 5 is threadedly connected to the movable rod 4, see [reference]. Figure 2 As shown, when the threaded rod 5 rotates via the movable rod 4, the threaded rod 5 will gradually descend, and when the threaded rod 5 descends, it will synchronously drive the reduction motor 9 to move. When the reduction motor 9 moves, the slide block 8 will slide on the surface of the support plate 6.

[0030] In an optional embodiment, a horizontal plate 31 is installed inside the rotating disk 10. The outer diameter of the rotating disk 10 matches the inner diameter of the steelmaking furnace 1. The other end of the threaded rod 5 passes through the movable rod 4 and connects to the pressure plate 17 and the horizontal plate 31. The threaded rod 5 is threadedly connected to the movable rod 4. As described above, since one end of the threaded rod 5 is connected to the horizontal plate 31, and the horizontal plate 31 is connected to the rotating disk 10, when the threaded rod 5 rotates, it will synchronously drive the horizontal plate 31 to rotate. When the horizontal plate 31 rotates, it will synchronously drive the rotating disk 10 to rotate. (See reference...) Figure 5As shown, while the rotating disk 10 rotates, it gradually descends along the inner wall of the steelmaking furnace 1. As the rotating disk 10 rotates, it descends synchronously with the threaded rod 5. When the rotating disk 10 rotates and descends, it synchronously drives the pressure knife 11 to rotate and descend along the inner wall of the steelmaking furnace 1. When the pressure knife 11 descends and contacts the inner wall of the steelmaking furnace 1, it removes the steel slag attached to the inner wall of the steelmaking furnace 1.

[0031] In an optional embodiment, one side of the inclined block A12 is an inclined surface. The inclined block A12 and the inclined block B18 are located on the same plane. As the inclined block A12 rotates with the rotating disk 10, the inclined surface of the inclined block A12 intermittently squeezes the inclined block B18. Multiple sets of force transmission blocks 19 are installed on one end of the pressure plate 17 near the rotating disk 10. A ball bearing is rotatably connected to one side of the inclined surface of the inclined block B18. As described above, when the rotating disk 10 rotates, it will synchronously drive the inclined block A12 to rotate. As the inclined block A12 rotates, the inclined surface of the inclined block A12 will contact the ball bearing on the inclined surface of the inclined block B18. The friction between the inclined block A12 and the ball bearing is small. Therefore, when the rotating disk 10 rotates, the inclined block A12 will not synchronously push the inclined block B18 to rotate, but will squeeze the inclined block B18 to slide upward.

[0032] In an optional embodiment, a bearing 16 is rotatably connected inside the pressure plate 17. The bearing 16 is slidably connected to multiple sets of third sliding grooves 15. When the threaded rod 5 rotates, it will synchronously drive the bearing 16 to rotate. Because the bearing 16 is rotatably connected to the pressure plate 17, the rotation of the bearing 16 will not drive the pressure plate 17 to rotate. As described above, when the inclined surface of the inclined block A12 contacts the inclined surface of the inclined block B18, the inclined block A12 is connected to the rotating disk 10, and the rotating disk 10 is positioned... When the inclined surface of inclined block A12 contacts the inclined surface of inclined block B18, inclined block A12 will press inclined block B18 to move away from the end of inclined block A12. Since inclined block B18 is fixedly connected to pressure plate 17, the movement of inclined block B18 will synchronously drive pressure plate 17 to move. After inclined block A12 continues to rotate, it will cause inclined block A12 to disengage from inclined block B18. After inclined block A12 disengages from inclined block B18, as... Figure 8As shown, at this time, the bearing 16 will slide down the multiple sets of third slide grooves 15 due to downward inertia. As the bearing 16 falls, it will simultaneously drive the pressure plate 17 to fall. When the pressure plate 17 falls, the inclined block B18 will contact the rotating disk 10. Furthermore, as the pressure plate 17 descends, multiple sets of force transmission blocks 19 will contact the horizontal plate 31. Thus, as the pressure plate 17 falls, it will transmit force to the rotating disk 10 through the inclined block B18 and the multiple sets of force transmission blocks 19, thereby applying a downward vibration force to the rotating disk 10. This vibration force assists the pressure knife 11 in removing slag from the inner wall of the steelmaking furnace 1 during the descent of the rotating disk 10. Because the pressure plate 17 is a solid design, it ensures that sufficient vibration force is applied to the rotating disk 10 during descent, and the solid design also prevents… The steel slag on the inner wall of the steelmaking furnace 1 is prevented from splashing outward when it is squeezed and detached by the pressure knife 11, thereby improving the safety of the working environment. The downward vibration force of the pressure plate 17 assists the pressure knife 11 to more easily remove the steel slag from the inner wall of the steelmaking furnace 1, preventing the problem of steel slag adhesion or difficulty in cleaning caused by simple squeezing, making slag removal smoother and more thorough. At the same time, the solid design of the pressure plate 17 can ensure that sufficient vibration force is applied to the rotating disk 10, making the slag removal process easier. On the other hand, it can prevent steel slag from splashing outward when it is squeezed and detached, preventing injury to operators or damage to equipment, and greatly improving the safety of the working environment. The specifications of the inclined surfaces of the inclined blocks A12 and B18 can be customized according to the actual situation, and the vibration force only plays an auxiliary role in detachment and will not affect the movement of the threaded rod 5 along the movable rod 4. Because the multiple sets of third slide grooves 15 are relatively short, and the height at which the inclined block A12 lifts the inclined block B18 is relatively low, the pressure plate 17 will only cause vibration to the rotating disk 10 when it descends.

[0033] In an optional embodiment, a movable ring 13 is rotatably connected to one end of the horizontal plate 31 near the pressure plate 17. One end of the movable ring 13 is connected to a rack 14, and the other end of the rack 14 extends through the pressure plate 17 to the other end of the pressure plate 17. Therefore, when the horizontal plate 31 rotates, refer to... Figure 9 As shown, because the movable ring 13 is connected to the rack 14 and the rack 14 extends through the pressure plate 17 to the other end, the movable ring 13 is limited by the limiting rack 14, so that when the horizontal plate 31 rotates, the horizontal plate 31 will not drive the movable ring 13 to rotate synchronously.

[0034] In an optional embodiment, one end of each of the multiple sets of first nozzles 20 is fixedly connected to a connecting pipe A21, and the other end of the multiple sets of connecting pipes A21 is connected to two sets of connecting valves 22. One end of each of the two sets of connecting valves 22 is connected to a connecting pipe B23, and the other end of the connecting pipe B23 is connected to a water supply device. The branch ends of each of the two sets of connecting valves 22 are connected to two sets of second nozzles 27. The four sets of second nozzles 27 are installed inside the pressure plate 17 and face the pressure knife 11. When using the equipment, the operator simultaneously turns on the water supply device. After the water supply device is turned on, in the initial state of the connecting valve 22, the end of the connecting valve 22 connected to the connecting pipe A21 is in the open state, and the end of the connecting valve 22 connected to the connecting pipe C26 is in the closed state. Then, after the water source enters the interior of the connecting valve 22, the water source will enter the interior of the connecting pipe A21 through the connecting valve 22. The connecting pipe A21 will spray the water source to the inner wall of the steelmaking furnace 1 through the multiple sets of first nozzles 20. When multiple sets of first nozzles 20 spray water, as mentioned above, the rotation of the threaded rod 5 synchronously drives the horizontal plate 31 to rotate. As the horizontal plate 31 rotates, it comes into contact with the water sprayed by the multiple sets of first nozzles 20 at intervals, causing the water to splash upon contact with the horizontal plate 31. This splashing causes the water to irregularly spray onto the inner wall of the steelmaking furnace 1. Consequently, when the residue adhering to the inner wall of the steelmaking furnace 1 comes into contact with the cold water, the thermal expansion and contraction effect causes the residue adhering to the inner wall of the steelmaking furnace 1 to break apart. The cracking and detachment of residues on the inner wall of the steelmaking furnace 1 reduces the adhesion of the residues and the load on the pressure knife 11 when cleaning the inner wall of the steelmaking furnace 1. The irregular cold water splash formed by the splashing of water source causes the residues on the inner wall to quickly crack and detach through the thermal expansion and contraction effect, reducing the resistance of the pressure knife 11 when cleaning the inner wall, reducing the mechanical wear and load of the pressure knife 11. At the same time, the cold water splashing promotes the auxiliary detachment of residues, reduces the direct wear of the pressure knife 11 on the inner wall of the steelmaking furnace 1, and indirectly extends the service life of the furnace body.

[0035] In an optional embodiment, a valve stem 24 is fixedly connected to one end of the shut-off valve, and the other end of the valve stem 24 extends outward through the connecting valve 22. A gear 25 is connected to the end of the valve stem 24 located outside the connecting valve 22. The gear 25 meshes with the rack 14. As described above, when the horizontal plate 31 rotates, it will not drive the movable ring 13 to rotate. When it is not rotating, the position of the rack 14 will not change. At this time, when the pressure plate 17 moves intermittently due to the movement of the inclined block A12, the movement of the pressure plate 17 will synchronously drive the first nozzle 20 and the second nozzle 27 to move upward. When the nozzle moves on the first nozzle 20, it will synchronously drive the connecting valve 22 to move through the connecting pipe A21. When the connecting valve 22 moves, it will synchronously drive the gear 25 to move. When the gear 25 moves, it will rotate through the rack 14. When the gear 25 rotates, it will drive the plug valve inside the connecting valve 22 to rotate through the valve stem 24. After the plug valve rotates, the connecting valve 22 will change from being connected to the connecting pipe A21 in the initial state to being connected to the connecting pipe C26, so that the water source that enters the connecting valve 22 will enter the connecting pipe C26.

[0036] In an optional embodiment, each of the two sets of connecting valves 22 is fixedly connected to a connecting pipe C26 at one end, and the other end of each of the two sets of connecting pipes C26 is connected to two sets of second nozzles 27. As described above, after the water source enters the connecting pipe C26, the water source will be sprayed outward through the four sets of second nozzles 27. When the water source is sprayed out through the four sets of second nozzles 27, because the second nozzles 27 are biased towards the pressure knife 11, the water source will be sprayed onto the pressure knife when it is sprayed out through the second nozzles 27. At the edge of 11, the residual slag on the inner wall of the steelmaking furnace 1 will generate a certain residual heat, and the pressure knife 11 will descend in a rotating posture. The pressure knife 11 will generate heat due to the rotational friction between it and the slag. At this time, the water source will cool down the pressure knife 11. When the water source comes into contact with the pressure knife 11, it will come into contact with the inner wall of the steelmaking furnace 1. After the water source comes into contact with the inner wall of the steelmaking furnace 1, it will descend along the inner wall of the steelmaking furnace 1, thereby better removing the slag attached to the inner wall of the steelmaking furnace 1 due to the effect of thermal expansion and contraction. As described above, when the inclined block A12 and the inclined block B18 come into contact and then separate, the pressure plate 17 will reset. When the pressure plate 17 resets, the gear 25 will come into contact with the rack 14 again. When the gear 25 rotates after coming into contact with the rack 14 again, the plug valve inside the connecting valve 22 will reset, allowing the water source to spray outward through multiple sets of first nozzles 20. Thus, when using the device, the pressure knife 11 is cooled down at regular intervals. Water is sprayed directionally onto the edge of the pressure knife 11 at regular intervals, thereby removing the heat generated by the rotational friction of the pressure knife 11 in time, preventing the pressure knife 11 from wearing or deforming due to high temperature, and ensuring that the process of the pressure knife 11 descending on the inner wall of the steelmaking furnace 1 to clean the residue is stable. At the same time, the water sprayed onto the pressure knife 11 will further contact the inner wall of the steelmaking furnace 1 and descend along the inner wall of the steelmaking furnace 1, continuously using the thermal expansion and contraction effect to act on the residue on the inner wall. In combination with local splashing, the residue is more comprehensively promoted to break and fall off.
