Description

TECHNICAL FIELD

[0001] The utility model relates to metal smelting sintering equipment technical field, concretely relates to a sintering fuel non -uniform cloth device. BACKGROUND

[0002] Sintering process is one of the key links in steel production, and its main purpose is to mix raw materials such as iron ore powder, fuel (such as coke powder) and flux (such as limestone), and make it partially melt through high temperature heating, and re-solidify to form sinter with certain mechanical strength and uniform chemical composition during the cooling process. Sinter has high permeability and mechanical strength, which can improve the reduction efficiency and production efficiency in the blast furnace ironmaking process. Sintering process not only improves the utilization rate of iron ore powder and reduces resource waste, but also improves the stability and economy of blast furnace operation, which is an important means of efficient utilization of iron ore resources. Strictly controlling the particle size of sinter solid fuel (usually coal powder or coke powder) within 0.5-3mm has obvious effect on sintering energy saving and consumption reduction. When the fuel particle size is <0.5mm, the burnout speed is too fast, the fuel belt is thin, and it is easy to be sucked away by negative pressure; when the fuel particle size is >3mm, the burnout speed is too slow, the combustion zone is too thick, the permeability of the material layer is poor, and the utilization coefficient decreases. Sintering process is carried out from top to bottom, which has the characteristics of high demand for fuel in the upper part of the material layer and low demand for fuel in the lower part of the material layer. However, the fuel segregation arrangement effect is not obvious through the current distribution means, resulting in waste of lower layer fuel.

[0003] Currently, the common distribution method of sintering machine is the combination of circular roller distributor and nine-roller distribution device. The circular roller distributor uniformly outputs the mixed raw materials through a rotating circular roller, and moves to the nine-roller distribution device, which further adjusts the particle distribution of the sintering material layer through nine parallel rollers. The rotation speed and height of the circular roller can be adjusted to control the thickness and uniformity of the distribution. Then, the nine-roller distribution device further adjusts the particle distribution of the sintering material layer. The fuel distribution in the sintering material after the distribution of the existing equipment is uniform, which affects the thermal efficiency of the sintering process.

The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the utility model.

[0028] Embodiment:

[0029] Reference Figures 1-7The embodiment provides a sintering fuel non-uniform distribution device 100, which comprises a main distribution mechanism 1 and a secondary distribution mechanism 2, the main distribution mechanism 1 is provided with a discharge port, the secondary distribution mechanism 2 comprises a material taking assembly 21, a material conveying assembly 22, a mixed material conveying assembly 23 and a distribution hopper 24, the material taking assembly 21, the mixed material conveying assembly 23 and the distribution hopper 24 are sequentially arranged, the material taking assembly 21 is arranged at a downstream end of the main distribution mechanism 1 to receive part of material output by the discharge port of the main distribution mechanism 1, the material conveying assembly 22 is arranged in parallel with the material taking assembly 21, and the output end of the material conveying assembly 22 and the output end of the material taking assembly 21 are connected with the input end of the mixed material conveying assembly 23, the mixed material conveying assembly 23 is arranged at the downstream of the material conveying assembly 22 to receive incoming material conveyed by the material taking assembly 21 and the material conveying assembly 22, mix the incoming material and then output, and the distribution hopper 24 is arranged at the downstream output end of the mixed material conveying assembly 23 to receive mixed material of the mixed material conveying assembly 23 and uniformly output the mixed material.

[0030] It can be known that, in the process of distributing the sintering material, the mixed material with low fuel content is loaded into the main distribution mechanism 1, the mixed material is distributed on the sintering trolley 3 of the sintering machine through the main distribution mechanism 1, and the first layer of sintering material is formed on the sintering trolley 3; when the main distribution mechanism 1 is distributing, part of the mixed material is intercepted from the discharge port of the main distribution mechanism 1 through the material taking assembly 21, and the intercepted part of the mixed material is conveyed into the mixed material conveying assembly 23, the material conveying assembly 22 is used for conveying fuel, part of the fuel is conveyed into the mixed material conveying assembly 23 through the material conveying assembly 22, the mixed material and the fuel are fully mixed through the mixed material conveying assembly 23, and finally the mixed material with high fuel content is output, the mixed material with high fuel content is conveyed to the distribution hopper 24 through the mixed material conveying assembly 23, and the mixed material with high fuel content is distributed on the first layer of sintering material through the distribution hopper 24 to form the second layer of sintering material, so that the distributed sintering material finally presents the distribution state that the fuel content of the upper layer of sintering material is high and the fuel content of the lower layer of sintering material is low. In the combustion process of the sintering machine, the ignition gun ignites the surface layer of the mixed material, and the mixed material is combusted from the upper layer to the lower layer under the action of the fan, because the fuel content of the upper layer is high, more heat can be provided for the first layer of sintering material during combustion, so that the combustion is more sufficient, and the thermal efficiency in the sintering process is improved. Therefore, the structure form that the main distribution mechanism 1 and the secondary distribution mechanism 2 are cooperatively distributed increases the fuel content of the upper layer of the mixed material, which can make the ignition gun more smoothly ignite the mixed material, and can provide more heat for the combustion of the lower layer of the mixed material, so that the combustion is more sufficient, and the thermal efficiency in the sintering process is improved.

[0031] It is illustrated that the mixed material with high fuel content refers to the fuel content in the mixed material being higher than that in the conventional mixed material, and the mixed material with low fuel content refers to the fuel content in the mixed material being lower than that in the conventional mixed material.

[0032] Further, the main distributing mechanism 1 comprises a mixing bin 11, a distributing gate 12 and a round roller feeder 13, the distributing gate 12 is installed at the discharging port of the mixing bin 11, the round roller feeder 13 is rotatably connected to the lower end of the distributing gate 12, and the material taking assembly 21 is arranged at the downstream end of the round roller feeder 13 to partially intercept the mixed material conveyed by the round roller feeder 13.

[0033] It can be known that the mixed material is stored in the mixing bin 11, the mixing bin 11 is arranged in the shape of large at the top and small at the bottom, so that the mixed material in the mixing bin 11 moves downward under the action of gravity and moves to the round roller feeder 13 through the distributing gate 12, and the mixed material is uniformly distributed downward along with the rotation of the round roller feeder 13. The amount of mixed material discharged from the mixing bin 11 is controlled by the control valve, so as to control the thickness of the distribution.

[0034] Further, the auxiliary distributing mechanism 2 further comprises a vibrating bin 25, the vibrating bin 25 is arranged between the material taking assembly 21 and the mixed material conveying assembly 23, the vibrating bin 25 comprises an input conveying belt 251, a material box 252, a vibrating motor 253, an output conveying belt 254 and a weighing sensor 255, the input conveying belt 251 is arranged at the head end of the material box 252, the output conveying belt 254 is arranged at the tail end of the material box 252, the input conveying belt 251 is arranged in butt joint with the material taking assembly 21, the output conveying belt 254 is arranged in butt joint with the mixed material conveying assembly 23, the vibrating motor 253 is installed on the material box 252, the weighing sensor 255 is installed in the material box 252, and the weighing sensor 255 is electrically connected with the material taking assembly 21.

[0035] It can be known that through the setting of the vibrating bin 25, the material taken by the material taking assembly 21 is conveyed into the material box 252 through the input conveyor 251, the weight of the conveyed mixed material is weighed by the weighing sensor 255 in the material box 252, and under the vibration of the vibrating motor 253, the material in the material box 252 moves towards the output conveyor 254 and is finally conveyed from the output conveyor 254 into the mixing conveying assembly 23. When the mixed material is conveyed into the material box 252, the weighing sensor 255 is pressed by the mixed material, and a pressure signal is transmitted. The material taking assembly 21 receives the signal transmitted by the weighing sensor 255 and makes corresponding actions accordingly; when the flow of the mixed material conveyed into the material box 252 is greater than the set value, the weighing sensor 255 transmits a signal, the material taking assembly 21 receives the corresponding signal and moves away from the side of the circular roller feeder 13, so that the material taking assembly 21 reduces the amount of mixed material taken; when the flow of the mixed material in the material box 252 is less than the set value, the weighing sensor 255 transmits a signal, the material taking assembly 21 receives the corresponding signal and moves away from the side of the circular roller feeder 13, so that the material taking assembly 21 increases the amount of mixed material taken. Thus, the amount of material taken by the material taking assembly 21 is automatically adjusted through the setting of the vibrating bin 25.

[0036] Further, the vibrating bin 25 further comprises a weighing partition 256, which is slidingly arranged in the material box 252 along the height direction of the material box 252. The weighing partition 256 and the bottom of the material box 252 form a mounting cavity 257, the weighing sensor 255 is mounted in the mounting cavity 257, and the top of the weighing sensor 255 is connected with the weighing partition 256, and the bottom of the weighing sensor 255 is fixedly connected with the material box 252.

[0037] It can be known that when the mixed material enters the material box 252, the mixed material presses on the weighing partition 256 and exerts a downward pressure on the weighing partition 256, so that the weighing partition 256 moves downward and compresses the weighing sensor 255, facilitating the weighing sensor 255 to weigh the weight of the mixed material. Through the setting of the weighing partition 256, the weighing sensor 255 is protected, and secondly, the weight of the material can be better transmitted to the weighing sensor 255.

[0038] Further, two vibrating motors 253 are arranged, and the two vibrating motors 253 are respectively mounted on the two sides of the material box 252.

[0039] It can be known that by symmetrically arranging the vibrating motors 253 on the two sides of the material box 252, the vibration is more balanced, and additionally, by arranging two vibrating motors 253, the vibration of the material box 252 can be increased, and the strength of the vibration can be improved.

[0040] Further, the material taking assembly 21 comprises a track 211, a driving member 212, and a material taking chute 213, the material taking chute 213 is slidingly connected to the track 211 by the driving member 212, the upstream end of the material taking chute 213 is arranged towards the circular roller feeder 13, the downstream end of the material taking chute 213 is arranged towards the input conveying belt 251, and the upstream end of the material taking chute 213 is higher than the downstream end of the material taking chute 213. Specifically, the weighing sensor 255 is electrically connected to the driving member 212, when the material taking chute 213 moves close to the circular roller feeder 13, the material taking amount of the material taking assembly 21 is increased; when the material taking chute 213 moves away from the circular roller feeder 13, the material taking amount of the material taking assembly 21 is decreased.

[0041] It can be known that the driving member 212 drives the material taking chute 213 to reciprocatingly slide along the track 211, when the weighing sensor 255 senses that the weight is greater than the set value, the weighing sensor 255 outputs a signal towards the driving member 212, so that the driving member 212 controls the material taking chute 213 to move away from the circular roller feeder 13, and the material taking amount is decreased, so that the mixed material entering the vibrating assembly is reduced, the weight sensed by the weighing sensor 255 is decreased, until the weight is decreased to the set value. When the weight sensed by the weighing sensor 255 is less than the set value, the weighing sensor 255 outputs a signal towards the driving member 212, so that the driving member 212 controls the material taking chute 213 to move close to the circular roller feeder 13, and the material taking amount is increased, so that the mixed material entering the vibrating assembly is increased, the weight sensed by the weighing sensor 255 is increased, until the weight is increased to the set value. The automatic adjustment of the material taking amount is realized. In the embodiment, the driving member 212 is a hydraulic motor, in other embodiments, the driving member 212 can also be a motor, or other components or structures capable of providing power.

[0042] Further, the upper end of the material distributing hopper 24 is open, and the upper end of the material distributing hopper 24 is connected to the mixed material conveying assembly 23, and the lower end of the material distributing hopper 24 is arranged as an elongated material distributing chute.

[0043] It can be known that the mixed material with high fuel content after mixing of the mixed material conveying assembly 23 enters the material distributing hopper 24 through the opening, and is output from the elongated material distributing chute below the material distributing hopper 24, so as to be evenly distributed on the first layer of mixed material to form a second layer of mixed material. The fuel content in the second layer of mixed material is higher than that in the first layer of mixed material.

[0044] The width of the circular roller feeder 13 is equal to the width of the elongated material distributing chute, and the material distributing hopper 24 is arranged corresponding to the circular roller feeder 13. Therefore, the mixed material distributed by the material distributing hopper 24 can just cover the mixed material distributed by the circular roller feeder 13.

[0045] Further, the mixing and conveying assembly 23 comprises a housing 231, stirring blades 232 rotationally connected in the housing 231, and a driving motor 233 mounted on the housing 231 and having an output end connected with the stirring blades 232. Specifically, a cylindrical cavity is arranged in the housing 231, and the stirring blades 232 are coaxially rotationally connected in the cylindrical cavity.

[0046] It can be known that the stirring blades 232 are driven to rotate by the driving motor 233, so that the mixed material and the fuel in the housing 231 are fully stirred.

[0047] It should be noted that the stirring blades 232 are helical stirring blades 232, which play a stirring and conveying role in the rotation process, and convey the mixed material in the housing 231 towards the downstream end.

[0048] Referring to Figure 1 Further, a sintering machine is provided, comprising a sintering trolley 3, and the sintering fuel non-uniform distributing device 100 described above, which is arranged above the sintering trolley 3, and the circular roller feeder 13 is arranged in butt joint with the sintering trolley 3, and the distributing hopper 24 is also arranged in butt joint with the sintering trolley 3, and the circular roller feeder 13 is arranged at the upstream end of the distributing hopper 24.

[0049] Specifically, an igniter is arranged above the sintering trolley 3, a fan is arranged below the sintering trolley 3, and filter holes are arranged on the sintering trolley 3. During the sintering process, the fan draws air, and the sintering material burns from top to bottom during the sintering process.

[0050] It can be known that the sintering fuel non-uniform distributing device 100 distributes the sintering material on the sintering trolley 3, and during the distribution process, the main distributing mechanism 1 first distributes the first layer of mixed material with low fuel content, and then the second layer of mixed material with high fuel content is distributed by the auxiliary distributing mechanism 2. When sintering, the second layer of mixed material with high fuel content is ignited by the igniter, and the fan draws air downward, so that the second layer of fuel is heated downward during the combustion process, and the first layer of mixed material with low fuel content is burned. Through such a structure, the sintering fuel is more easily ignited during the combustion process, and because the fuel content of the upper layer of sintering material is high, it has a good heating effect on the lower layer of sintering fuel during the combustion process, and the sintering is more complete and the thermal efficiency is higher.

[0051] Further, the bottom material distributing mechanism 4 is arranged on the sintering trolley 3 and arranged upstream of the sintering fuel non-uniform distributing device 100.

[0052] It can be known that the bottom material distributing mechanism 4 is used for distributing the bottom material, that is, a thick bottom material is first distributed on the sintering trolley 3 by the bottom material distributing mechanism 4 during work, then the first layer of sintering material is distributed on the bottom material layer by the main distributing mechanism 1, then the second layer of sintering material is distributed on the first layer of sintering material by the auxiliary distributing mechanism 2. The content of fuel in the second layer of sintering material is higher than that in the first layer of sintering material, and more heat can be generated during the combustion process. Because of the existence of the fan, the fan blows air downward, so that the second layer of sintering material burns from top to bottom during the combustion process, so that the second layer of sintering material heats the first layer of sintering material during the combustion process, so that the first layer of sintering material can obtain more heat, so that the sintering is more sufficient, and the sintering efficiency is higher.

[0053] The preferred embodiments of the present application are described above, but are not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
