Description

Technical Field

[0001] This utility model relates to the field of metallurgical engineering technology, and in particular to an energy-saving and consumption-reducing blast furnace that is easy to operate. Background Technology

[0002] A blast furnace is a vertical shaft furnace for ironmaking. It has a steel plate shell and is lined with refractory bricks. It consists of a throat, a furnace body, and other parts. It uses hot air to burn coke to generate carbon monoxide, which reduces iron ore to produce molten iron, which is used for steelmaking and other purposes.

[0003] Existing blast furnaces mainly consist of a vertical structure including the throat, body, waist, belly, and hearth. The furnace shell encloses a refractory lining to form a closed cavity, with tuyeres evenly distributed in the upper part of the hearth. Its core function is to reduce iron ore by burning coke to generate carbon monoxide, thereby separating and removing molten iron from slag. Simultaneously, it utilizes cooling walls, hot blast stoves, and other systems to maintain a high-temperature reaction environment and recover energy.

[0004] Some blast furnaces suffer from high fuel consumption and energy consumption due to incomplete combustion of fuel ratios during operation and the inability to adjust them in time. Therefore, an energy-saving and energy-efficient blast furnace that is easy to operate is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an easy-to-operate, energy-saving, and consumption-reducing blast furnace, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-operate, energy-saving and consumption-reducing blast furnace, comprising a furnace body, a charging box fixedly connected to the outside of the furnace body, a driving assembly installed on the inner wall of the charging box, a rotating shaft fixedly connected to the outside of the driving assembly, a limiting block slidably connected to the inner wall of the charging box, a moving plate fixedly connected to the outside of the limiting block, the rotating shaft slidably connected to the inner wall of the moving plate, and a charging plate fixedly connected to the outside of the moving plate.

[0008] As a further technical solution of this utility model, a feeding pipe is installed on the inner wall of the feeding box, and a square opening is provided on the inner wall of the feeding plate.

[0009] As a further technical solution of this utility model, a feeding pipe is fixedly connected to the bottom of the feeding box, and an inclined pipe is fixedly connected to the outside of the furnace body.

[0010] As a further technical solution of this utility model, the inclined tube is fixedly connected to two protective boxes, and a cylinder is installed on the inner wall of the protective box.

[0011] As a further technical solution of this utility model, the driving ends of the two cylinders are fixedly connected to a movable tube, the outside of the movable tube is fixedly connected to two fixed tubes, and the inner wall of the fixed tube is fixedly connected to a movable column.

[0012] As a further technical solution of this utility model, a sliding tube is slidably connected to the outside of the fixed tube, and a fixed ring is fixedly connected to the outside of the two sliding tubes. The outside of the fixed ring is fixedly connected to the outside of the protective box. A spring is fixedly connected to the inner wall of the sliding tube, and a sliding column is fixedly connected to the other end of the spring.

[0013] This invention provides an easy-to-operate, energy-saving and consumption-reducing blast furnace, which has the following advantages compared with the prior art:

[0014] 1. This design is an easy-to-operate, energy-saving and consumption-reducing blast furnace. The rotation of the disc drives the rotating shaft to rotate around the center of the disc. The position change of the rotating shaft can push the position of the moving plate to move on a fixed trajectory.

[0015] 2. This design is an easy-to-operate, energy-saving and consumption-reducing blast furnace. The position change of the moving column can squeeze the sliding column to move backward, thereby causing the spring to deform. When the spring returns to its original position, it can push the sliding column to make close contact with the moving column, thereby sealing the charging port. When the blast furnace charging channel is not in use, it can be sealed to reduce heat loss, maintain the high temperature inside the furnace, prevent gas leakage, and ensure production safety and environmental protection.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides an easy-to-operate, energy-saving and consumption-reducing blast furnace technical solution: It includes a furnace body 1, with a charging box 2 fixedly connected to the outside of the furnace body 1 to fix its position. The charging box 2 stores a large amount of raw materials and protects the charging structure. A driving assembly is installed on the inner wall of the charging box 2, and a rotating shaft 6 is fixedly connected to the outside of the driving assembly, driving the rotating shaft 6 to change position. A limiting block 7 is slidably connected to the inner wall of the charging box 2, limiting the movement of the limiting block 7 so that it can only move laterally. A moving plate 8 is fixedly connected to the outside of the limiting block 7, allowing the moving plate 8 to move only laterally. The rotating shaft 6 is slidably connected to the inside wall of the moving plate 8, and changes in the position of the rotating shaft 6 can drive changes in the position of the moving plate 8. A charging plate 9 is fixedly connected to the outside of the moving plate 8, and changes in the position of the moving plate 8 can drive changes in the position of the charging plate 9.

[0024] The drive assembly includes a motor 4, which is externally mounted on the inner wall of the feeding box 2, providing a fixed mounting position for the motor 4. A disc 5 is fixedly connected to the drive end of the motor 4; starting the motor 4 causes the disc 5 to rotate. A rotating shaft 6 is externally fixedly connected to the outside of the disc 5; the rotation of the disc 5 causes the rotating shaft 6 to rotate around the center of the disc 5. A feeding pipe 3 is installed on the inner wall of the feeding box 2 for storing large quantities of ingredients. A square opening 10 is provided on the inner wall of the feeding plate 9, allowing the ingredients to fill the opening and move with the feeding plate 9, thus completing quantitative feeding. A discharge pipe 11 is fixedly connected to the bottom of the feeding box 2 for transferring ingredients.

[0025] Reference Figure 3 and Figure 5 An inclined tube 12 is fixedly connected to the outside of the furnace body 1, allowing the ingredients to move freely into the furnace body 1 due to gravity when entering the channel. Two protective boxes 15 are fixedly connected to the outside of the inclined tube 12 to provide external protection for the drive structure. Cylinders 16 are installed on the inner wall of the protective boxes 15 to protect the cylinders 16. Moving tubes 13 are fixedly connected to the drive ends of the two cylinders 16. Activating the cylinders 16 causes the moving tubes 13 to move. Two fixed tubes 18 are fixedly connected to the outside of the moving tubes 13, causing the two fixed tubes 18 to move.

[0026] A movable column 19 is fixedly connected to the inner wall of the fixed tube 18. Changes in the position of the fixed tube 18 can cause the movable column 19 to move. A sliding tube 17 is slidably connected to the outside of the fixed tube 18, limiting its sliding position. A fixing ring 14 is fixedly connected to the outside of the two sliding tubes 17, and the fixing ring 14 is fixedly connected to the outside of the protective box 15. The protective box 15 fixes the position of the two sliding tubes 17 through the fixing ring 14. A spring 21 is fixedly connected to the inner wall of the sliding tube 17, fixing one end of the spring 21. A sliding column 20 is fixedly connected to the other end of the spring 21. The outside of the sliding column 20 contacts the outside of the movable column 19, so that when the movable column 19 moves, it can push the sliding column 20 to change position, causing the spring 21 to deform. The return of the spring 21 ensures that the sliding column 20 and the outside of the movable column 19 are in close contact.

[0027] The working principle of this utility model is as follows: When the proportion needs to be adjusted, the drive motor 4 is activated, causing the drive end of the motor 4 to rotate, thereby causing the disc 5 to rotate. This allows the specific specifications of the batching material to move down from the inner wall of the square opening 10 and then down from the inner wall of the feeding pipe 11 to complete the feeding. Since the size of the square opening 10 is fixed, the amount of material carried is fixed, requiring multiple transports. The batching ratio is automatically adjusted to achieve uniform distribution of materials and good permeability in the blast furnace, reduce segregation and slippage of the material column, and reduce the coke ratio and fuel consumption of the blast furnace. By monitoring parameters such as temperature, pressure, and gas composition in the blast furnace in real time, the air volume, air temperature, and oxygen ratio are adjusted in a timely manner to keep the blast furnace in the best operating state, thereby improving production efficiency and energy utilization.

[0028] In use, only two cylinders 16 need to be activated, causing the position of the driving end of the two cylinders 16 to move the position of the moving tube 13, thereby exposing the feed port of the inclined tube 12 and completing the feeding. When not in use, the reverse driving cylinder 16 can drive the moving tube 13 to move backward, thereby simultaneously driving the fixed tube 18 to move and pushing the moving column 19 to move. The position change of the moving column 19 can squeeze the sliding column 20 to move backward, thereby causing the spring 21 to deform. When the spring 21 returns to its original position, it can push the sliding column 20 to make close contact with the moving column 19, thereby sealing the feed port. When the blast furnace feed channel is not in use, it can be sealed to reduce heat loss, maintain the high temperature inside the furnace, prevent gas leakage, and ensure production safety and environmental protection; it can also isolate air intrusion, stabilize the reaction inside the furnace, reduce dust overflow, improve the environment, and reduce equipment wear.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
