Description

Technical Field

[0001] The present invention relates to the technical field of metal smelting, and particularly to a remote iron-smelting centralized control device and method. Background Technique

[0002] Iron smelting is a process of extracting metallic iron from iron-containing minerals, mainly including the blast furnace method, direct reduction method, smelting reduction method, and plasma method. From a metallurgical perspective, iron smelting is the reverse process of iron rusting and gradual mineralization. Simply put, pure iron is reduced from iron-containing compounds. In actual production, pure iron does not exist, and what is obtained is an iron-carbon alloy. Currently, the blast furnace is still the main force in iron smelting in the metallurgical industry, and its advantages are long furnace life, large production capacity, low energy consumption, and easy operation.

[0003] In the prior art, when using the blast furnace method for iron smelting, the feeding position at the blast furnace mouth is in a high-temperature and dust environment for a long time, and the environment is harsh. In the existing blast furnace, due to the fixed single-track design during feeding, the feeding vehicle can only run along a single path. In actual use, when there is a material accumulation phenomenon inside the blast furnace, feeding needs to be temporarily stopped. At this time, the feeding vehicle moving to a high position with iron ore not only has the hidden danger of high-altitude falling objects, but also causes the empty feeding vehicle below to be unable to be loaded in time, resulting in the reduction of iron-smelting efficiency.

[0004] Therefore, we propose a remote iron-smelting centralized control device and method to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of the present invention is to provide a remote iron-smelting centralized control device and method to solve the problems raised in the above background technique.

Between the inner surfaces of the front and rear sides of the second orbit frame, a second low-level orbit and a high-level orbit are symmetrically and fixedly connected. The orbit switching component is used to switch the path state of the orbit component and includes electric push rods. The number of electric push rods is set to two.

[0009] Preferably, the traveling mechanism includes a mounting plate, a material conveying hopper is rotatably connected to the top of the mounting plate, a flat motor is installed at the center of the bottom of the mounting plate, the output end of the flat motor rotatably penetrates through the bottom of the mounting plate and extends upward, and the output end of the flat motor is fixedly connected to the bottom of the material conveying hopper.

[0010] Preferably, connecting frames are symmetrically and fixedly connected to the bottom of the mounting plate near the front and rear side edges, frame plates are fixedly connected to the bottoms of the two connecting frames, first wheel shafts are symmetrically rotatably connected to the positions near the right two corners between the outer surfaces of the two frame plates on the opposite sides, and second wheel shafts are symmetrically rotatably connected to the positions near the left two corners between the outer surfaces of the two frame plates on the opposite sides.

[0011] Preferably, a traveling motor is installed at the position near the right side of the bottom of the mounting plate, a fourth pulley is fixedly connected to the output end of the traveling motor, a third pulley is fixedly connected to the position near the middle of the outer surface of one of the second wheel shafts, a second transmission belt is sleeved between the outer surfaces of the third pulley and the fourth pulley, moving wheels are fixedly connected to both ends of one of the first wheel shafts and the second wheel shafts, reinforcing wheels are fixedly connected to both ends of the other two first wheel shafts and the second wheel shafts, the adjacent moving wheels and reinforcing wheels are clamped on the top and bottom of the first lower track, and the opposite surfaces of the two frame plates and the opposite surfaces of the two first lower tracks are attached.

[0012] Preferably, gears are fixedly connected to the positions near the ends of the outer surfaces of the two first wheel shafts, the upper and lower adjacent gears are meshed, first pulleys are fixedly connected to the positions near the gears on the outer surfaces of the first wheel shafts, second pulleys are fixedly connected to the positions on the outer surfaces of the second wheel shafts that cooperate with the first pulleys, and a first transmission belt is sleeved between the outer surfaces of the adjacent first pulleys and second pulleys.

[0013] Preferably, grooves are formed on the outer surfaces of the moving wheels, and convex ridges with semicircular tops that match the grooves are provided on the tops of the first lower track, the second lower track, the upper track, the lane-changing track, the straight-through track, and the blanking track.

[0014] Preferably, the outer surface of the reinforcement wheel is provided with outwardly protruding spline ridges, and spline grooves matching the spline ridges are provided at the bottoms of the first low-level track, the second low-level track, the high-level track, the lane-changing track, the straight-through track, and the blanking track.

[0015] A method for a remote iron-smelting centralized control device includes the following steps:

[0016] S1. When in use, when it is necessary to deliver iron-smelting raw materials to the iron-smelting blast furnace, a certain number of traveling mechanisms are installed on the first track rack according to the actual situation. When installing, the moving wheels and reinforcement wheels in the traveling mechanism clamp the first low-level track and then the traveling motor is started. At this time, with the cooperation of the fourth pulley, the second transmission belt, the third pulley, the first wheel shaft, the second wheel shaft, the first pulley, the second pulley, and the first transmission belt, the four moving wheels and the four reinforcement wheels are clamped on the surfaces of the two first low-level tracks and then rotate in the reverse direction and move onto the first low-level track.

[0017] S2. After all the required number of traveling mechanisms are installed on the surface of the first low-level track, iron-smelting raw materials are replenished into the material transport hopper and the traveling motor is started, and then the material transport hopper is driven to travel towards the feeding port position of the iron-smelting blast furnace.

[0018] S3. After the traveling mechanism equipped with iron-smelting raw materials moves to the left end position of the first low-level track, by starting the electric push rod to push the U-shaped frame and the side plate to descend, the lane-changing track can connect the high-level track and the first low-level track, or the straight-through track can connect the first low-level track and the second low-level track, or the blanking track can be connected to the first low-level track.

[0019] S4. When the blanking track is connected to the first low-level track, the material transport hopper that continues to travel will complete the feeding operation. When the straight-through track, the first low-level track, and the second low-level track are connected, the material transport hopper after feeding can return to the low position on the left for reloading. When the lane-changing track, the high-level track, and the first low-level track are connected, the material transport hopper equipped with raw materials can directly travel to the low position to wait without discharging materials.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. When in use, when the iron-smelting blast furnace fails and needs to be temporarily shut down, by controlling the lane-changing track with the electric push rod to connect the first low-level track and the high-level track, the material transport hopper will enter the standby high-level track from the first low-level track through the lane-changing track, and finally move to a height close to the ground along the high-level track and stop waiting. This design enables the material transport hopper equipped with iron-smelting raw materials to safely return to the ground through the standby track when the iron-smelting blast furnace is temporarily shut down, avoiding the hidden danger of high-altitude falling objects and not affecting the feeding efficiency at the same time, ensuring that feeding and iron-smelting can continue after the blast furnace maintenance is completed, and ensuring the iron-smelting efficiency.

[0022] 2. During use, the cooperation between the blanking track and the first low-level track enables the material transport hopper to complete the blanking operation simply by continuing to move forward. The through track, the first low-level track, and the second low-level track cooperate to form a dual-track feeding route, ensuring that ironmaking raw materials can be continuously fed into the ironmaking blast furnace and the air transport hopper does not affect the material transport hopper during the feeding process. During the entire ironmaking process, only the telescopic movement of the electric push rod and the forward and reverse rotation of the flat motor and the traveling motor need to be remotely controlled to remotely and continuously feed the material transport hopper into the ironmaking blast furnace, eliminating the need for manual participation and improving the ironmaking efficiency and safety.

[0023] 3. During use, when the material transport hopper moves on tracks such as the first low-level track, the grooves on the surface of the moving wheels cooperate with the convex ridges on the track to play a limiting role. While ensuring the stability of the movement of the material transport hopper, since the upper part of the convex ridge is semi-circular, dust particles with relatively large particle sizes are difficult to stay above the track. The surface of the reinforcing wheels located below is provided with spline ridges, which will engage with the spline grooves below the track during movement, thereby driving the material transport hopper to move forward stably. This design enables the material transport hopper to stably and reliably complete the feeding operation of ironmaking raw materials during the use of the ironmaking blast furnace, with a simple structure and good use effect.

Specific embodiments

[0036] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Refer to Figures 1 - 10 As shown: A centralized control device for remote ironmaking includes a blast furnace for ironmaking 1. A track switching assembly 3 is provided inside the blast furnace for ironmaking 1. A track assembly 2 and a traveling mechanism 5 are provided outside the blast furnace for ironmaking 1. The track assembly 2 includes a first track frame 201 and a second track frame 203. A first low-level track 202 is symmetrically installed between the inner surfaces of the front and rear sides of the first track frame 201. A second low-level track 204 and a high-level track 205 are symmetrically and fixedly connected between the inner surfaces of the front and rear sides of the second track frame 203. The track switching assembly 3 is used to switch the path state of the track assembly 2 and includes an electric push rod 301. The number of electric push rods 301 is set to two. A U-shaped frame 302 is fixedly connected between the bottoms of the two electric push rods 301. Side plates 303 are symmetrically and fixedly connected to the bottom of the U-shaped frame 302. A lane-changing track 304, a straight-through track 305, and a blanking track 306 are fixedly connected between the outer surfaces of the opposite sides of the two side plates 303.

[0038] The interior of the ironmaking blast furnace 1 is hollow, and a feeding port 11 is provided near the upper part. The tops of two electric push rods 301 are fixedly connected to the inner top of the ironmaking blast furnace 1, and the U-shaped frame 302 is located above the feeding port 11. The feeding port 11 is used to feed ironmaking raw materials into the interior of the ironmaking blast furnace 1. After the ironmaking raw materials are fed into the interior of the ironmaking blast furnace 1, hot air is blown in from the bottom of the furnace, and coke burns to generate high temperature and carbon monoxide reducing gas, which reduces the iron oxide in the iron ore to liquid pig iron. The flux and the impurities in the ore form slag, which floats on the surface of the molten iron. The liquid pig iron and slag are discharged from the iron notch and slag notch respectively. The whole process is carried out continuously to achieve efficient and large-scale production of molten iron. The electric push rod 301 is used to control the height of the U-shaped frame 302. The U-shaped frame 302 is connected to the side plate 303, so that the electric push rod 301 can control the lifting and adjustment of the switching track 304, the straight-through track 305 and the feeding track 306. The shape design of the U-shaped frame 302 also ensures that the transport hopper 516 will not be blocked when moving on the switching track 304 at the highest position.

[0039] The left end of the first low-level track 202 and the right end of the second low-level track 204 are at the same height. The height of the high-level track 205 is higher than that of the second low-level track 204. The switching track 304 cooperates with the first low-level track 202 and the high-level track 205. The straight-through track 305 cooperates with the first low-level track 202 and the second low-level track 204. The feeding track 306 cooperates with the first low-level track 202. The switching track 304 is inclined upward, and the feeding track 306 is inclined downward. A limiting block 307 is fixedly connected to the left end of the feeding track 306. During use, under the control of the electric push rod 301, when the switching track 304 descends to the same height as the first low-level track 202, it will connect the first low-level track 202 on the right side and the high-level track 205 on the left side, so that the traveling mechanism 5 can move onto the high-level track 205. When the straight-through track 305 is flush with the first low-level track 202, the first low-level track 202 and the second low-level track 204 are in a connected state. At this time, after the traveling mechanism 5 has emptied the raw material port, it can move to the lower right side to discharge and replenish the raw materials without affecting the traveling mechanism 5 that is continuously feeding on the right side. When the feeding track 306 descends and docks with the first low-level track 202, a feeding path is formed. When the transport hopper 516 continues to move at the junction of the first low-level track 202 and the feeding track 306, the left moving wheels 508 and the reinforcing wheels 509 will move onto the feeding track 306 and the height will decrease accordingly, so that the discharging port of the transport hopper 516 is inclined downward, and the ironmaking raw materials are fed into the feeding port 11 to complete the feeding.

[0040] The traveling mechanism 5 includes a mounting plate 515. A material conveying hopper 516 is rotatably connected to the top of the mounting plate 515. A flat motor 517 is installed at the center of the bottom of the mounting plate 515. The output end of the flat motor 517 rotatably penetrates through the bottom of the mounting plate 515 and extends upward. The output end of the flat motor 517 is fixedly connected to the bottom of the material conveying hopper 516. The material conveying hopper 516 is used to hold iron-making raw materials. The unobstructed position on the lower side is the pouring opening, and a shielding plate is provided on the other side. The flat motor 517 is used to control the rotation of the material conveying hopper 516, so that the material conveying hopper 516 can face the iron-making blast furnace 1 on either side, so that when it tilts when moving upward, the materials are difficult to fall.

[0041] Connecting frames 518 are symmetrically and fixedly connected to the bottom of the mounting plate 515 near the front and rear side edges. Frame plates 501 are fixedly connected to the bottoms of the two connecting frames 518. First wheel shafts 502 are symmetrically rotatably connected to positions near the two corners on the right side between the outer surfaces of the two frame plates 501. Second wheel shafts 503 are symmetrically rotatably connected to positions near the two corners on the left side between the outer surfaces of the two frame plates 501. The mounting plate 515 is connected through the connecting frames 518 and the frame plates 501, and is simultaneously rotatably connected to the material conveying hopper 516, serving as the main frame in the traveling mechanism 5. The first wheel shafts 502 and the second wheel shafts 503 are the drive shafts of the moving wheels 508 and the reinforcement wheels 509.

[0042] A traveling motor 519 is installed at the position near the right side of the bottom of the mounting plate 515. A fourth pulley 514 is fixedly connected to the output end of the traveling motor 519. A third pulley 512 is fixedly connected to a position near the middle of the outer surface of one of the second wheel shafts 503. A second transmission belt 513 is sleeved between the outer surfaces of the third pulley 512 and the fourth pulley 514. Moving wheels 508 are fixedly connected to both ends of one of the first wheel shafts 502 and the second wheel shafts 503. Reinforcement wheels 509 are fixedly connected to both ends of the other two first wheel shafts 502 and the second wheel shafts 503. The adjacent moving wheels 508 and reinforcement wheels 509 are clamped on the top and bottom of the first low-position track 202. The opposite surfaces of the two frame plates 501 are attached to the opposite surfaces of the two first low-position tracks 202. When the traveling motor 519 is started to drive the fourth pulley 514, the fourth pulley 514 will drive the third pulley 512 to rotate through the second transmission belt 513 when it rotates. At this time, the third pulley 512 will drive the first wheel shaft 502 connected to it to rotate. The first wheel shafts 502 and the second wheel shafts 503 at the same height are connected by a first pulley 504, a second pulley 505 and a first transmission belt 506. Therefore, the first wheel shafts 502 and the second wheel shafts 503 will rotate synchronously and in the same direction.

[0043] At positions near the ends of the outer surfaces of the two first-round shafts 502, gears 507 are fixedly connected. The upper and lower adjacent gears 507 are meshed. At positions on the outer surfaces of the first-round shafts 502 near the gears 507, first pulleys 504 are fixedly connected. At positions on the outer surfaces of the second-round shafts 503 that cooperate with the first pulleys 504, second pulleys 505 are fixedly connected. A first transmission belt 506 is sleeved between the outer surfaces of the adjacent first pulleys 504 and second pulleys 505. The upper and lower adjacent first-round shafts 502 are drivingly connected through the meshed gears 507. Therefore, the two first-round shafts 502 will rotate synchronously and in opposite directions. Driven by the traveling motor 519, the two first-round shafts 502 and the second-round shafts 503 will rotate synchronously and drive the four moving wheels 508 and the four reinforcement wheels 509 to be clamped on the surfaces of the two first low-position tracks 202 and then rotate in the opposite direction. Furthermore, the frame plate 501 and the connecting frame 518 drive the mounting plate 515 to move forward on the first low-position track 202.

[0044] Grooves 510 are formed on the outer surfaces of the moving wheels 508. On the tops of the first low-position track 202, the second low-position track 204, the high-position track 205, the lane-changing track 304, the straight-through track 305, and the blanking track 306, there are convex ridges with a semi-circular top that match the grooves 510. Grooves 510 are formed on the surfaces of the upper moving wheels 508. The convex ridges on the matching tracks can play a role in limiting the position. While ensuring the moving stability of the material conveying hopper 516, since the upper part of the convex ridge is semi-circular, dust particles with a relatively large particle size are difficult to stay above the track.

[0045] On the outer surfaces of the reinforcement wheels 509, there are outwardly protruding spline ridges 511. On the bottoms of the first low-position track 202, the second low-position track 204, the high-position track 205, the lane-changing track 304, the straight-through track 305, and the blanking track 306, there are spline grooves that match the spline ridges 511. The reinforcement wheels 509 are provided with spline ridges 511 on their surfaces. When moving, they will engage with the spline grooves below the track, thereby driving the material conveying hopper 516 to move stably.

[0046] Effects and usage methods achieved by the present invention: When in use, when it is necessary to deliver iron-making raw materials to the iron-making blast furnace 1, a certain number of traveling mechanisms 5 are installed on the first track frame 201 according to actual conditions. During installation, the moving wheel 508 and the reinforcement wheel 509 in the traveling mechanism 5 clamp the first low-position track 202, and then the traveling motor 519 is started to drive the fourth pulley 514. When the fourth pulley 514 rotates, it will drive the third pulley 512 to rotate through the second transmission belt 513. At this time, the third pulley 512 will drive the first wheel shaft 502 connected thereto to rotate, and the first wheel shaft 502 and the second wheel shaft 503 adjacent to the same height are driven by the first pulley 504, the second pulley 505 and the first transmission belt 506. The first axle 502 and the second axle 503 are connected, so the first axle 502 and the second axle 503 will rotate synchronously in the same direction, and the upper and lower adjacent first axles 502 are connected by gears 507 that mesh with each other, so the two first axles 502 will rotate synchronously in the opposite direction. Driven by the travel motor 519, the two first axles 502 and the second axle 503 will rotate synchronously and drive the four moving wheels 508 and the four reinforcement wheels 509 to clamp on the surfaces of the two first low-level rails 202 and rotate in the opposite direction, and then drive the mounting plate 515 to move forward on the first low-level rail 202 through the frame plate 501 and the connecting frame 518. Through this method, the required number of travel mechanisms 5 are installed on the first low-level rail 202 for conveying ironmaking raw materials;

[0047] When the ironmaking blast furnace 1 needs to feed ironmaking raw materials during the ironmaking process, raw materials are added to the hopper 516 in the traveling mechanism 5 on the first low-level track 202. Then, after starting the forward rotation of the traveling motor 519, the moving wheels 508 and the reinforcing wheels 509 will rotate, driving the hopper 516 to travel along the first low-level track 202 towards the feeding port 11 at the high position of the ironmaking blast furnace 1. At this time, after starting the contraction of the electric push rod 301 above the feeding port 11, it can drive the U-shaped frame 302 to move upward. When the U-shaped frame 302 moves upward, it will drive the side plates 303 on the front and rear sides to move synchronously, further enabling the right end of the feeding track 306 to be butted with the high position on the left side of the first low-level track 202, forming a feeding path. When the hopper 516 continues to move at the intersection of the first low-level track 202 and the feeding track 306, the left moving wheels 508 and the reinforcing wheels 509 will move onto the feeding track 306 and their height will decrease accordingly, causing the discharge opening of the hopper 516 to tilt downward, so that the ironmaking raw materials are put into the feeding port 11 to complete the feeding. Subsequently, after the traveling motor 519 flips, the hopper 516 will retract back onto the first low-level track 202. At this time, the electric push rod 301 is started to push the U-shaped frame 302 down to a medium height and make the straight-through track 305 butted with the first low-level track 202 and the second low-level track 204. Then, the hopper 516 in the empty car state continues to move forward and moves to the left low position through the second low-level track 204 for feeding. This design enables the hopper 516 to continuously travel and continuously feed ironmaking raw materials into the feeding port 11 of the ironmaking blast furnace 1, and then replenish materials in turn from the other side. The empty car does not need to return for alternate feeding, greatly improving the utilization rate and ironmaking efficiency of the ironmaking blast furnace 1;

[0048] When the hopper 516 in the empty car state moves to the low position on the left second low-level track 204 for feeding, start the flat motor 517 to drive the hopper 516 to rotate 180°, so that its discharge opening faces the ironmaking blast furnace 1 again. When feeding ironmaking raw materials from the left, it only needs to move to above the first low-level track 202 first and then control the hopper 516 to rotate back to the state where the discharge opening faces left to continue the feeding operation. After the feeding is completed, it returns to the right side of the first low-level track 202 to re-queue and feed the hopper 516. During the entire feeding process, only the telescopic of the electric push rod 301 and the forward and reverse rotation of the flat motor 517 and the traveling motor 519 need to be remotely controlled to control the hopper 516 to continuously feed the ironmaking blast furnace 1 remotely, without manual participation, improving the ironmaking efficiency and safety;

[0049] When the charging hopper 516 is filled with ironmaking raw materials and the ironmaking blast furnace 1 fails and needs to be temporarily shut down, the electric push rod 301 is activated to push the U-shaped frame 302 down to the lowest position. At this time, the right end of the lane-changing track 304 will be docked with the left end of the first low-level track 202, and its left end will be docked with the right end of the high-level track 205. At this time, the charging hopper 516 will pass through the lane-changing track 304 from the first low-level track 202 and then enter the spare high-level track 205. Finally, it moves along the high-level track 205 to a height close to the ground and stops waiting. This design enables the charging hopper 516 filled with ironmaking raw materials to safely return to the ground through the spare track when the ironmaking blast furnace 1 is temporarily shut down, avoiding the hidden danger of high-altitude falling objects and not affecting the feeding efficiency at the same time, ensuring that feeding and ironmaking can continue after the blast furnace maintenance is completed, and ensuring the ironmaking efficiency;

[0050] When the charging hopper 516 moves on tracks such as the first low-level track 202 through the moving wheels 508 and the reinforcing wheels 509, grooves 510 are provided on the surface of the upper moving wheels 508, which can play a limiting role in cooperation with the convex ribs on the track, ensuring the moving stability of the charging hopper 516. At the same time, since the upper part of the convex rib is semicircular, dust particles with larger particle sizes are difficult to stay above the track. At the same time, spline ribs 511 are provided on the surface of the lower reinforcing wheels 509, which will engage with the spline grooves below the track during movement, so as to drive the charging hopper 516 to move forward stably. This design enables the charging hopper 516 to stably and reliably complete the feeding operation of ironmaking raw materials during the use of the ironmaking blast furnace 1, with a simple structure and good use effect.

[0051] The wiring diagrams of the ironmaking blast furnace 1, the electric push rod 301, the flat motor 517 and the traveling motor 519 in the present invention belong to the common knowledge in the field. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the ironmaking blast furnace 1, the electric push rod 301, the flat motor 517 and the traveling motor 519 will not be explained in detail.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
