Description

Technical Field

[0001] This utility model relates to the field of blast furnace smelting equipment, and in particular to a blast furnace top-charging coke smelting material layer thickness adjustment mechanism based on reducing heat loss. Background Technology

[0002] Blast furnace smelting equipment refers to equipment consisting of the blast furnace body, blast furnace dust collector, blast furnace blower, blast furnace hot blast stove, and molten iron ladle car. During blast furnace production, ore powder, coke, and flux for slag formation are charged from the top of the furnace. Preheated air is blown in from the tuyeres located at the bottom of the furnace along the perimeter. At high temperatures, the carbon in the coke burns with the oxygen in the blown air to produce carbon monoxide and hydrogen. As the hydrogen rises inside the furnace, it removes the oxygen from the iron ore powder, thereby reducing it to iron.

[0003] However, in the use of existing blast furnace smelting equipment, since the volumes of ore powder, coke and flux for slag making are different, the feed inlet is prone to blockage when being transported into the blast furnace, which affects the smelting process.

[0004] Furthermore, after the raw materials are directly transported into the blast furnace smelting equipment, the raw materials are prone to accumulate inside the equipment, resulting in uneven heating of the raw materials inside, which undoubtedly prolongs the smelting time and thus affects the smelting effect and smelting efficiency.

[0005] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: This example addresses the problem in existing blast furnace smelting equipment where, due to the different volumes of ore powder, coke, and flux used for slag formation, the feed inlet is prone to blockage during transport into the blast furnace, thus affecting the smelting process.

[0027] Please see Figure 1 - Figure 3 As shown, this embodiment is a material layer thickness adjustment mechanism for blast furnace top coking based on reducing heat loss. It includes a furnace body 1, a base 2 fixedly installed at the bottom of the furnace body 1, a feed inlet 101 opened at the top of the furnace body 1, and an adjustment component 3 fixedly installed at the top of the furnace body 1. The furnace body 1 also has the required flue gas structure and heating structure fixedly installed, which are all existing technologies. Their specific types and structures will not be described in detail here.

[0028] The regulating component 3 includes a housing 301, a rotating rod 302, and a cutting plate 303. The housing 301 is fixedly installed on the top of the furnace body 1, the cutting plate 303 is fixedly installed inside the housing 301, the rotating rod 302 is movably installed in the housing 301, a feed pipe 304 is fixedly installed on the top of the housing 301, a motor is fixedly installed on the top of the housing 301, the output end of the motor is fixedly connected to the rotating rod 302, and a rotating blade is fixedly installed on the rotating rod 302. The rotating rod 302 is driven to rotate by the motor, and the rotating blade drives the material to be stirred and pushes the material towards the feed inlet 101.

[0029] Multiple cutting plates 303 are provided, and the cutting plates 303 are inclined downwards and evenly spaced apart. A lead screw 306 is movably installed on one side of the housing 301. The top of the lead screw 306 is connected to the rotating rod 302 via a belt. During the movement of the material, the material and the cutting plates 303 are squeezed against each other, thereby breaking up the agglomerated material.

[0030] Specifically, the material is conveyed into the housing 301 through the feed pipe 304. At this time, the rotating rod 302 rotates to stir the material inside the housing 301. During the mixing process, the cutting plate 303 disperses the clumps of material, effectively improving the feeding efficiency and preventing the material from clogging the feed inlet 101.

[0031] Example 2: This example addresses the problem that when raw materials are directly fed into a blast furnace smelting equipment, they tend to accumulate inside the equipment, leading to uneven heating and thus extending the smelting time, which in turn affects the smelting effect and efficiency.

[0032] Please see Figure 4 - Figure 5 As shown, this utility model also includes a vibrating plate 305, which is movably installed in the base 2. A first fixed tube 310 and a second fixed tube 311 are fixedly installed inside the base 2. The first fixed tube 310 is located at the center of the base 2. Multiple second fixed tubes 311 are provided and are evenly distributed around the first fixed tube 310. A first movable rod 312 is movably installed in the first fixed tube 310, and a second movable rod 313 is movably installed in the second fixed tube 311.

[0033] A connecting plate 307 is fixedly installed on one side of the housing 301. The bottom of the lead screw 306 is movably connected to the connecting plate 307. A movable block 308 is movably installed on the lead screw 306 through a thread. An airbag 309 is fixedly installed on the connecting plate 307. The bottom of the movable block 308 is fixedly connected to the top of the airbag 309. The lead screw 306 is provided with a reciprocating thread. The movable block 308 forms a reciprocating transmission structure with the lead screw 306 through the reciprocating thread. When the lead screw 306 rotates, the movable block 308 gradually moves up and down under the action of the thread. When the movable block 308 moves down, the airbag 309 is compressed and contracted. When the movable block 308 moves up, the airbag 309 expands.

[0034] An airbag 314 is fixedly installed in the fixed tube 310. The bottom of the movable rod 312 is fixedly connected to the airbag 314. A spring is fixedly installed at the bottom of the movable rod 313. One end of the spring is fixedly connected to the inner wall of the fixed tube 311. The tops of the movable rod 312 and the movable rod 313 abut against the vibrating plate 305. The airbag 314 is fixedly connected to the airbag 309 through a pipeline.

[0035] When airbag 309 is compressed and contracted, gas enters airbag 314, causing airbag 314 to expand. This expands airbag 314, which in turn moves rod 312 upward, thereby pushing vibrating plate 305 upward. At this time, rod 313 moves in fixed tube 311, and the spring is stretched. When airbag 309 expands, airbag 314 gradually contracts. Under the action of the spring, vibrating plate 305 returns to its original position. The above steps are repeated, causing vibrating plate 305 to move up and down, at which time vibrating plate 305 vibrates.

[0036] Specifically, the material is first initially dispersed by the rotating rod 302 and the cutting plate 303. After dispersion, the material falls into the base 2. While the rotating rod 302 rotates, it drives the vibrating plate 305 to vibrate. The vibration makes the material on the vibrating plate 305 evenly distributed, further avoiding the accumulation of raw materials and effectively improving smelting efficiency and smelting effect.

[0037] Combining Embodiments 1 and 2, the material is conveyed into the shell 301 through the feed pipe 304. At this time, the rotating rod 302 rotates to stir the material inside the shell 301. During the stirring and mixing process, the cutting plate 303 disperses the clumps of material, effectively improving the feeding efficiency and preventing the material from clogging the feed inlet 101. The rotating rod 302 and the cutting plate 303 initially disperse the material, which then falls into the base 2. While the rotating rod 302 rotates, it drives the vibrating plate 305 to vibrate, which makes the material on the vibrating plate 305 evenly distributed, further preventing the accumulation of raw materials and effectively improving the smelting efficiency and smelting effect.

[0038] The working process and principle of this utility model are as follows:

[0039] First, the material is conveyed into the housing 301 through the feed pipe 304. At this time, the rotating rod 302 rotates to stir the material inside the housing 301. During the mixing process, the cutting plate 303 disperses the clumps of material, effectively improving the feeding efficiency and preventing the material from clogging the feed inlet 101.

[0040] Furthermore, the material is initially dispersed by the rotating rod 302 and the cutting plate 303. After dispersion, the material falls into the base 2. While the rotating rod 302 rotates, it drives the vibrating plate 305 to vibrate. The vibration makes the material on the vibrating plate 305 evenly distributed, further avoiding the accumulation of raw materials and effectively improving smelting efficiency and smelting effect.

[0041] In summary, the present invention, through the setting of the adjustment component 3, not only avoids material blockage at the feed inlet 101, but also effectively prevents raw material accumulation, thereby improving smelting efficiency and smelting effect.
