Description

Technical Field

[0001] The present invention relates to the technical field of steelmaking deoxidation treatment, and more particularly to a deoxidizer feeding device for a steelmaking converter. Background Art

[0002] Converter steelmaking uses hot metal, scrap steel, and ferroalloys as the main raw materials. Without relying on external energy, the steelmaking process is completed in the converter by the physical heat of the molten iron itself and the heat generated by the oxidation reaction between the components of the molten iron and oxygen. When the converter blowing is approaching the end point, the molten steel contains a certain amount of dissolved oxygen. Therefore, it is necessary to deoxidize the molten steel to ensure the quality of the steel. Adding a deoxidizer to the molten steel is the main means of deoxidation. Ferrosilicon is one of the most commonly used deoxidizers. Silicon in ferrosilicon is a strong deoxidizing element. Silicon and oxygen are easily combined to form silicon dioxide and release a large amount of heat. While deoxidizing, it can increase the temperature of the molten steel and reduce the energy consumption of steelmaking.

[0003] However, in the actual use process, uneven particle size, impurities, or high humidity of ferrosilicon can easily cause blockage of the conveying pipeline of the feeding device, which requires manual dredging, affecting the normal feeding. Manual dredging is time-consuming and laborious and is extremely likely to miss the best deoxidation opportunity, thus affecting the quality of the molten steel. For this reason, we propose a deoxidizer feeding device for a steelmaking converter to solve the above problems. Summary of the Invention

[0019] Technical effects and advantages of the present invention:

[0020] 1. Two semi-circular pipes are combined to form a conveying pipe for conveying ferrosilicon deoxidizer. When the deoxidizer in the conveying pipe is blocked, the deoxidizer will accumulate in the pipe, which will increase the weight of the conveying pipe and cause a downward displacement. At the same time, by using the linkage of the connecting pipe and the movable hinge rod, they are gradually separated during the downward movement of the conveying pipe, so as to expand the orifice of the conveying pipe, allowing the deoxidizer to fall, playing a role in preventing blockage. Finally, the reset spring is used to restore the original state.

[0021] 2. By using the staggered arrangement of the first sector piece and the second sector piece, on the one hand, the falling deoxidizer blocks hit on the sector piece, making the deoxidizer falling from the conveying pipe more pulverized and scattered in the molten steel, playing a role in improving the deoxidation effect. On the other hand, when the molten steel reacts with the deoxidizer, a large amount of heat energy will be released. The air at the converter mouth rushes upward into the fan blade drum due to the high temperature, and the hot air flow pushes the sector piece, causing the fan blade drum to rotate. By using the meshing relationship between the teeth of the sector drum and the gear, one semi-circular pipe is further separated from the other semi-circular pipe, so that the deoxidizer blocks stuck between the two semi-circular pipes due to the too-fast reset of the semi-circular pipes can be released, playing a role in recycling the deoxidizer debris.

Detailed implementation manners

[0031] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the drawings in the present invention. In addition, the forms of each structure described in the following embodiments are merely examples, and a deoxidizer dosing device for a steelmaking converter involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0032] Refer to Figure 1 , the present invention provides a deoxidizer dosing device for a steelmaking converter, including a dosing component 1. The bottom end of the dosing component 1 is fixedly connected to a hanging plate component 2. The bottom end of the hanging plate component 2 is movably sleeved with a converter component 3. The top of the dosing component 1 is fixedly connected to a converter moving component 4.

[0033] In this embodiment, it should be specifically supplemented that the dosing component 1 plays a role in preventing blockage of the deoxidizer pipeline. The hanging plate component 2 has the effect of improving the deoxidation effect. The converter component 3 is a steelmaking converter, and the converter moving component 4 is a working platform and control device during steelmaking. The specific structures and working principles of the above components will be described in detail later.

[0034] Refer to Figure 2, the feeding component 1 includes a feeding hopper 101. Connecting blocks 102 are fixedly connected to both sides of the feeding hopper 101. Fixed long rods 103 are fixedly connected to the bottoms of the two connecting blocks 102. A pipeline opening and closing component 104 is fixedly connected and communicated at the bottom of the feeding hopper 101. Springs 105 are fixedly connected to both ends of the bottom of the feeding hopper 101 near the edge positions. An activity tube 106 is movably sleeved in the hollow part inside the pipeline opening and closing component 104. The bottoms of the two springs 105 are fixedly connected to the activity tube 106.

[0035] In this embodiment, it should be specifically supplemented that the structure of the activity tube 106 is a circular tube with a ring fixedly sleeved on the side. The bottoms of the two springs 105 are respectively fixedly connected to the top of the ring, and there are two chutes at the bottom of the ring.

[0036] Refer to Figure 3 , the pipeline opening and closing component 104 includes a hollow pipeline 1041. Connecting pipes 1042 are fixedly connected to both sides of the hollow pipeline 1041. Activity folding rods 1043 are movably sleeved at the ends of the two connecting pipes 1042 away from the hollow pipeline 1041. Semi-circular pipelines 1044 are fixedly connected to one ends of the two activity folding rods 1043. A toothed plate 1045 is fixedly connected to one side of one semi-circular pipeline 1044. The two semi-circular pipelines 1044 and the activity tube 106 are connected by sliders, and the two semi-circular pipelines 1044 can slide horizontally in the circular chute of the activity tube 106.

[0037] In this embodiment, it should be specifically supplemented that the hollow pipeline 1041 is a pipeline with a hollow inner wall. The inner wall of the activity tube 106 is movably sleeved in the hollow part of the inner wall of the hollow pipeline 1041. There is a rack at the bottom of the end of the toothed plate 1045 away from the semi-circular pipeline 1044 for meshing with a gear. The feeding hopper 101 is a deoxidizer feeding device. The deoxidizer enters from the feeding hopper 101, flows through the hollow pipeline 1041 and is conveyed to the semi-circular pipeline 1044. When the deoxidizer is blocked and cannot flow at the semi-circular pipeline 1044, the weight of the semi-circular pipeline 1044 increases due to the accumulation of the deoxidizer, and then it moves downward. The activity folding rod 1043 is fixedly connected to the semi-circular pipeline 1044, so the activity folding rod 1043 also moves downward. Since the connecting pipe 1042 is inclined outward, the activity folding rod 1043 moves outward while moving downward, and then the two semi-circular pipelines 1044 are separated, expanding the area of the pipe orifice of the conveying pipeline formed by the two semi-circular pipelines 1044 to dredge the blockage. The fact that the two semi-circular pipelines 1044 can slide horizontally in the circular chute of the activity tube 106 is not shown in the drawings due to its simple structure.

[0038] Refer to Figure 4, the suspension plate assembly 2 includes a mounting plate 201. Inside the middle of the mounting plate 201, a fan blade drum 202 is rotatably sleeved. In the middle of the bottom of the mounting plate 201, a conical plate 203 is fixedly connected. At both ends of the bottom of the mounting plate 201, converter hooks 204 are fixedly connected. In the front of the top of the mounting plate 201, a first gear 205 is rotatably connected. In the middle of the top of the first gear 205, a first bevel gear 206 is fixedly connected. The side of the first gear 205 meshes with the top end of the fan blade drum 202. The side of the first bevel gear 206 meshes with a second bevel gear 207. At the end of the second bevel gear 207 away from the first bevel gear 206, a second gear 208 is fixedly connected. The side of the second gear 208 meshes with a toothed plate 1045. On one side of the second gear 208, a rotating rod is fixedly connected and a fixed ring rod 209 is movably sleeved on the side of the rotating rod. The bottom end of the fixed ring rod 209 is fixedly connected to the top of the mounting plate 201. On both sides of the top of the mounting plate 201, fixed long rods 103 are fixedly connected. At the edge positions on both sides of the top of the mounting plate 201, first motor groups 407 are fixedly connected.

[0039] In this embodiment, it should be specifically supplemented that the deoxidizer in the conveying pipeline can enter the converter from the round hole. The conical plate 203 is a pipe shell with a large bottom surface and a small top surface, which is used to guide the hot air flow from bottom to top to gather at the top pipe orifice.

[0040] Refer to Figure 5 , the fan blade drum 202 includes a drum body 2021. On the side of the top of the drum body 2021, gear teeth 2022 are fixedly connected. In the middle of the side of the drum body 2021, a collar 2023 is fixedly sleeved. On the side of the collar 2023, an annular groove is provided and sliding beads 2024 are placed in the annular groove.

[0041] In this embodiment, it should be specifically supplemented that the sliding beads 2024 placed in the collar 2023 are in contact with the inside of the mounting plate 201 to realize the rotation of the drum body 2021. The function of the sliding beads 2024 is to reduce friction.

[0042] Refer to Figure 6 , at the top end of the inner wall of the drum body 2021, six first sector-shaped pieces 2025 are fixedly connected. At the bottom end of the inner wall of the drum body 2021, six second sector-shaped pieces 2026 are fixedly connected.

[0043] In this embodiment, it should be specifically supplemented that the first sector-shaped pieces 2025 and the second sector-shaped pieces 2026 have the same structure. The middle of every two adjacent first sector-shaped pieces 2025 corresponds to one of the bottom second sector-shaped pieces 2026. The first sector-shaped pieces 2025 and the second sector-shaped pieces 2026 are obliquely fixed on the inner wall of the drum body 2021, so that the air flow from bottom to top can blow to make the drum body 2021 rotate.

[0044] Refer toFigure 7 , the converter assembly 3 includes a smelting furnace 301. Hook side ears 302 are fixedly connected to both sides of the smelting furnace 301. A lifting rope block 303 is fixedly connected to the front of the smelting furnace 301. Converter hooks 204 are rotatably connected to the sides of the two hook side ears 302. A second motor group 408 is rotatably sleeved inside the lifting rope block 303.

[0045] Refer to Figure 8 , the converter moving assembly 4 includes an operating platform 401. A cylinder 402 is fixedly connected to the top of the operating platform 401. A ladle 403 is fixedly connected to the inner side of the bottom of the operating platform 401. Air pipes 404 are fixedly communicated with both sides of the bottom end of the cylinder 402. Movable rods 405 are movably sleeved inside the inner sides of the two air pipes 404 away from the cylinder 402. One ends of the two movable rods 405 are fixedly connected to a movable plate 406. Two first motor groups 407 are fixedly connected to the top of the movable plate 406. A second motor group 408 is fixedly connected to one side of the movable plate 406.

[0046] In this embodiment, it should be specifically supplemented that the operating platform 401 is a steelmaking workbench. The telescopic movement of the movable rod 405 is realized by using the cylinder 402 and the air pipes 404, and then the translation of the movable plate 406 is realized. Both the first motor group 407 and the second motor group 408 are assemblies of a motor and a rope. The first motor group 407 realizes the up and down movement of the lifting plate and then realizes the up and down movement of the converter. The second motor group 408 is connected to the lifting rope block 303 to lift the bottom of the converter and realize the tilting of the converter. The above technologies are all existing technologies and will not be described in detail here.

[0047] Working principle of the present invention: The deoxidizer enters from the feed hopper 101, flows through the hollow pipe 1041 and is conveyed to the semi-circular pipe 1044. When the deoxidizer is blocked and cannot flow at the semi-circular pipe 1044, the weight of the semi-circular pipe 1044 increases due to the accumulation of the deoxidizer, and then it moves downward. The movable folding rod 1043 is fixedly connected to the semi-circular pipe 1044, so the movable folding rod 1043 also moves downward. Since the connecting pipe 1042 is inclined outward, when the movable folding rod 1043 moves downward, it also moves outward, and then the two semi-circular pipes 1044 are separated, expanding the orifice area of the conveying pipe formed by the two semi-circular pipes 1044 to dredge the blockage. When the middle of the conveying pipe is blocked, the mass of the semi-circular pipe 1044 returns to the initial state. Under the action of the spring 105, the movable pipe 106, the movable folding rod 1043, and the semi-circular pipe 1044 are all reset. In addition, when the deoxidizer falls from the lower orifices of the two semi-circular pipes 1044, it will hit the first sector piece 2025 and the second sector piece 2026, further pulverizing the agglomerated deoxidizer and scattering it in the molten steel, playing a role in improving the deoxidation effect. When the molten steel reacts with the deoxidizer, a large amount of heat energy is released. The air at the top port of the smelting furnace 301 surges upward due to the high temperature and enters the fan blade drum 202. The hot air flow pushes the first sector piece 2025 and the second sector piece 2026, and then the fan blade drum 202 rotates. By using the meshing relationship between the gear teeth 2022 and the first gear 205, the first bevel gear 206 drives the second bevel gear 207 to rotate, and the second bevel gear 207 drives the second gear 208 to rotate. The second gear 208 meshes with the toothed plate 1045, and the toothed plate 1045 moves, further separating the semi-circular pipe 1044 connected to the toothed plate 1045 from the other semi-circular pipe 1044, releasing the deoxidizer block stuck between the two semi-circular pipes 1044 due to the too-fast reset of the semi-circular pipe 1044, playing a role in recycling the deoxidizer debris.
