Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sintering machine, and particularly relates to a sintering machine material distribution structure with fuel self-adaptive distribution and a sintering machine system. BACKGROUND

[0002] The operation of the material distribution system equipment of the sintering machine directly affects the yield and quality of the sintered ore. The quality and yield of the sintered ore directly affect the production of the blast furnace and the improvement of the iron yield, quality and various economic and technical indexes, thereby affecting the cost control. Therefore, the improvement of the sintering machine material distribution device is of great significance. The ideal material distribution method should be that the particle size of the mixed material gradually increases from top to bottom, and the fuel gradually decreases. Such material distribution has higher heat utilization rate, and is beneficial to the improvement of the permeability of the material layer and the yield and quality of the sintered ore.

[0003] Currently, there are three kinds of material distribution methods. One is a mixed material bin, a circular roller feeder and a reflection plate material distribution. The advantages of this material distribution method are stable equipment operation and simple process flow. The disadvantages are that the circular roller and the reflection plate are prone to material adhesion, the mixed material flow is uneven, the material surface is uneven, the firing rate is affected, and the particle size of the sintered ore is affected. The segregation material distribution cannot meet the requirements of the sintering process. Another one is a mixed material bin, a wide rubber belt and a nine-roller material distributor. The advantages of the wide rubber belt feeder are that the material blocking phenomenon at the outlet of the small material bin is improved, the drop of the mixed material is reduced, and the damage rate of the small balls is reduced. The third one is a shuttle material distributor, a circular roller feeder and a multi-roller material distribution. The advantages of this method are uniform material distribution and beneficial to the improvement of the yield and quality of the sintered ore. When the shuttle material distributor is running, the particle size distribution of the mixed material along the width direction of the sintering machine body is relatively uniform, and the effect is good. When the shuttle material distributor is fixed, the particle size of the mixed material has a relatively large segregation, and the material distribution effect is poor. The current three kinds of material distribution methods all have problems such as uneven distribution of the mixed material, and the particle size distribution of the upper and lower layers cannot present the ideal distribution state of gradually increasing particle size from top to bottom. This makes the sintering machine not effectively utilize the fuel during work, and also reduces the yield and quality of the sintered ore. In addition, the surface distribution of the sintered ore fuel is uneven, which leads to a low firing rate.

[0004] In view of this, it is necessary to provide a sintering machine material distribution structure with fuel self-adaptive distribution and a sintering machine system to solve or at least alleviate the above-mentioned defects. SUMMARY

[0038] Please refer to the attached Figures 1-6 The present application provides a sintering machine fuel adaptive distribution structure in one embodiment, which comprises a feeding device 10 and a plurality of roller distribution devices 20 located below the feeding device 10. First of all, it needs to be pointed out that the existing distribution methods will all have the problem of uneven distribution of mixed materials, and the particle size distribution of the upper and lower layers is not ideal, which makes the sintering machine cannot effectively utilize fuel when working, and also makes the yield of sintering ore decrease. The present application can effectively solve the above defects in the prior art by setting a sintering machine fuel adaptive distribution structure. The specific implementation is as follows:

[0039] The plurality of roller distribution devices 20 comprise an inclined conveying table 210, a plurality of roller distribution mechanisms 220 and a first driving mechanism 230; wherein the inclined conveying table 210 comprises a high-position end 211 and a low-position end 212 which are oppositely arranged along the running direction of the sintering machine trolley 50, the low-position end 212 extends downwardly from the high-position end 211, and the high-position end 211 is located below the feeding device 10 to receive the sintering material from the feeding device 10.

[0040] Specifically, the feeding device 10 is used to provide sintering material, the plurality of roller distribution devices 20 are used to receive sintering material and transmit it into the sintering machine trolley 50, the plurality of roller distribution devices 20 comprise an inclined conveying table 210, a plurality of roller distribution mechanisms 220 and a first driving mechanism 230, the inclined conveying table 210 is used to receive sintering material, and the inclined conveying table 210 also has a discharge opening 213 for sintering material to fall into the sintering machine trolley 50, as an example, the discharge opening 213 can be arranged in a rectangular shape, the discharge opening 213 is arranged at the end of the movement track of the sintering material along the inclined conveying table 210, and its size length corresponds to the plurality of roller distribution mechanisms 220, it should be noted that the corresponding arrangement here means that the length of the discharge opening 213 corresponds to the length of the plurality of roller distribution mechanisms 220 along the extension direction of the inclined conveying table 210, so that the sintering material transmitted by each conveying roller 222 can fall into the sintering machine trolley 50 through the discharge opening 213, please refer to FIG. 5 for details.

[0041] Wherein, the inclined conveying table 210 comprises a high-position end 211 and a low-position end 212 which are oppositely arranged along the running direction of the sintering machine trolley 50, the low-position end 212 is arranged downwardly from the high-position end 211, the inclined conveying table 210 arranged in this way is convenient for the sintering material to roll towards the low-position end 212 of the inclined conveying table 210 after falling onto the inclined conveying table 210, and the high-position end 211 of the inclined conveying table 210 needs to be located below the feeding device 10 to receive the sintering material conveyed by the feeding device 10.

[0042] The multi-roller material distribution mechanism 220 is arranged above the inclined conveying table 210, and includes two support seats 221 arranged opposite to both sides of the inclined conveying table 210 and a plurality of conveying rollers 222 arranged along the extension direction of the inclined conveying table 210 at intervals. The support seat 221 is fixed to the top of the inclined conveying table 210, and the interval distance between each conveying roller 222 and the inclined conveying table 210 decreases from the high end 211 to the low end 212. The conveying roller 222 is rotatably connected between the two support seats 221. The inclined conveying table 210 also has a discharge opening 213 for the sintered material to fall into the sintering machine trolley 50. The first driving mechanism 230 is in transmission connection with the conveying roller 222, and is used to drive the conveying roller 222 to rotate, thereby driving the sintered material on the inclined conveying table 210 to move along the axial direction of the conveying roller 222 to the discharge opening 213, so as to distribute the sintered material into the sintering machine trolley 50 located below the inclined conveying table 210.

[0043] In detail, the multi-roller material distribution mechanism 220 is used to drive the sintered material to move towards the discharge opening 213 to fall into the sintering machine trolley 50. The multi-roller material distribution mechanism 220 is arranged above the inclined conveying table 210, and includes two support seats 221 arranged opposite to both sides of the inclined conveying table 210 and a plurality of conveying rollers 222 arranged along the extension direction of the inclined conveying table 210 at intervals. The support seat 221 is used to mount and fix the conveying roller 222 on the inclined conveying table 210, so that the conveying roller 222 is rotatably connected between the two support seats 221, and the interval distance between each conveying roller 222 and the inclined conveying table 210 decreases from the high end 211 to the low end 212 of the inclined conveying table 210.

[0044] It is worth mentioning that preferably, the spacing distance between each of the conveying rollers 222 and the inclined conveying table 210 can refer to the vertical distance from the center line of each of the conveying rollers 222 to the inclined conveying table 210, which is arranged in a decreasing manner from the high end 211 to the low end 212 of the inclined conveying table 210, and the vertical distance is adapted to the particle size of different materials, for example, so as to make the largest particle size of the sintered material falling first stop at the first conveying roller 222 with a larger spacing distance, and then be driven to the discharge opening 213 by the rotation of the first conveying roller 222 to fall into the sintering trolley 50 first, and then the sintered material with a particle size smaller than the maximum particle size cannot be stopped by the first conveying roller 222, and the remaining sintered material continues to roll back along the inclined conveying table 210, and so on. Since the spacing distance is arranged in a decreasing manner towards the low end 212, the sintered material with a larger particle size will be stopped by the conveying roller 222 corresponding to the current particle size, and the current sintered material will be conveyed to the discharge opening 213 by the rotation of the conveying roller 222,

[0045] It can be understood that the material is generally equivalent to a spherical shape, and falls from the discharge opening 213 to the sintering trolley 50 by converting the potential energy of gravity into kinetic energy, so that the material can be self-adapted to be laid in the sintering trolley 50, and the sintered material with a large particle size falls first and is laid in the lowermost layer of the sintering trolley 50, and so on, thereby finally achieving the ideal distribution state of the sintered material in the sintering trolley 50, i.e., the particle size gradually increases from top to bottom, which greatly improves the utilization rate of fuel, improves the permeability of the material layer, and improves the yield and quality of the sintered ore.

[0046] The first driving mechanism 230 is fixedly connected with the conveying roller 222, and the first driving mechanism 230 is used to drive the rotation of the conveying roller 222, thereby driving the sintered material to roll to the discharge opening 213. It is worth noting that the conveying roller 222 can be a threaded roller, which can better guide the sintered material to roll to the discharge opening 213, or can be a circular roller 124 or other types. Considering the higher efficiency of guiding the sintered material, preferably, the conveying roller 222 can be a threaded roller, which can be set according to specific needs by those skilled in the art.

[0047] In a preferred embodiment, the number of the conveying rollers 222 can be nine, for example, a nine-roller distribution mechanism commonly used in a distribution mechanism. In other embodiments, the number can also be seven, i.e., a seven-roller distribution mechanism. Considering that the nine-roller distribution mechanism divides the sintered material into nine particle size intervals, the adaptive hierarchical structure of the sintered material is better. Preferably, the number of the conveying rollers 222 can be nine, and the specific number can be determined by those skilled in the art according to the particle size of the sintered material.

[0049] It should be noted that the coal powder sticking device 30 is used to provide the sticking of the coal powder and the sintered material, so that the surface of the sintered material is uniformly distributed after the coal powder is stuck, the coal powder sticking device 30 is arranged between the feeding device 10 and the multi-roller material distribution mechanism 220, and is arranged close to the discharge port (not marked in the figure) of the feeding device 10, the coal powder sticking device 30 comprises an inclined storage mechanism 310 and a second driving mechanism 320, the inclined storage mechanism 310 is used to store the coal powder, wherein the inclined storage mechanism 310 comprises a porous coal powder plate 311, a movable powder pressing plate 312 and a coal powder bin 313 with two open ends, the porous coal powder plate 311 is covered on one side of the coal powder bin 313 close to the high end 211, wherein the covering means that the porous coal powder plate 311 is covered on one side of the coal powder bin 313 close to the high end 211, and the coal powder can only seep out from the hole groove of the porous coal powder plate 311, and the remaining positions are sealed and covered; the porous coal powder plate 311 is arranged towards the discharge port of the feeding device 10, the movable powder pressing plate 312 is movably arranged along the inner wall of the coal powder bin 313 and close to the low end 212, the coal powder in the coal powder bin 313 seeps out from the porous coal powder plate 311 and sticks to the sintered material through the pushing of the movable powder pressing plate 312, therefore the coal powder bin 313 needs to be inclined and arranged below the feeding device 10, and the porous coal powder plate 311 needs to be arranged towards the discharge port of the feeding device 10, so that the sintered material falling directly can stick to the coal powder seeping out from the porous coal powder plate 311, wherein the sidewall of the coal powder bin 313 is provided with a coal powder supplement port (not marked in the figure) for filling the coal powder, part of the coal powder is pushed out at the same time, and new coal powder is supplemented from the coal powder supplement port.

[0050] Wherein, the second driving mechanism 320 is fixedly connected with the movable powder pressing plate 312, the second driving mechanism 320 drives the movable powder pressing plate 312 to reciprocate along the inner wall of the coal powder bin 313, so as to push the coal powder in the coal powder bin 313 out of the porous coal powder plate 311, so that the sintered material from the feeding device 10 sticks to the coal powder.

[0051] Preferably, the second driving mechanism 320 comprises a push-pull mechanism 321, a crank slider mechanism 322 and a driving motor 323; wherein the push-pull mechanism 321 comprises a push plate rotating support 3210, a swing push plate 3211 and a connecting block (not shown in the figure); wherein the push plate rotating support 3210 is arranged above the coal powder bonding device 30 and close to the low end 212, the swing push plate 3211 is in a strip shape, and the swing push plate 3211 is swingably connected around the push plate rotating support 3210; the connecting block is connected between the swing push plate 3211 and the movable powder pressing plate 312; the slider 3220 of the crank slider mechanism 322 is connected with the swing push plate 3211; the driving motor 323 is used to drive the movement of the crank slider mechanism 322, and the swing push plate 3211 is swung through the slider 3220 to push the movable powder pressing plate 312 to reciprocate along the inner wall of the coal powder bin 313.

[0052] It is worth noting that the second driving mechanism 320 comprises a push-pull mechanism 321, a crank slider mechanism 322 and a driving motor 323, wherein the push-pull mechanism 321 comprises a push plate rotating support 3210, a swing push plate 3211 and a connecting block, the push plate rotating support 3210 is arranged above the coal powder bonding device 30 and close to the low end 212, so that the push plate rotating support 3210 is located on the side close to the movable powder pressing plate 312, facilitating the movement of the movable powder pressing plate 312 driven by the swing push plate 3211, the swing push plate 3211 is in a strip shape, the light and agile structure of the strip shape is easy to swing, and it can also be in a plate shape or other shapes, one end of the swing push plate 3211 is swingably connected around the push plate rotating support 3210, which can be swingably connected through a pin shaft, or can be other hinged ways, which can be selected according to specific needs by those skilled in the art, the connecting block is used to connect the swing push plate 3211 and the movable powder pressing plate 312, so the connecting block is arranged between the swing push plate 3211 and the movable powder pressing plate 312.

[0053] Further, the crank slider mechanism 322 comprises a crank (not labeled in the figure) and a slider 3220, and it can be understood that the crank slider mechanism 322 is a relatively mature system for converting rotation into movement, and thus its specific structure will not be described in detail here. The slider 3220 of the crank slider mechanism 322 is fixed to the swing pushing plate 3211, the driving motor 323 drives the crank of the crank slider mechanism 322 to rotate, and the crank drives the slider 3220 to move along the swing pushing plate 3211 in the process of rotation, so that the swing pushing plate 3211 swings around the pushing plate rotating support 3210, thereby pushing the movable powder pressing plate 312 back and forth.

[0054] It is worth mentioning that the driving motor 323 of the second driving mechanism 320 can also be a telescopic motor, which is fixedly connected with the swing pushing plate 3211.
