Description

Technical Field

[0001] The utility model relates to a sintering cooling device, in particular to an arc plate type sintering machine layered material discharging cooling device, belonging to the technical field of sintering. Background Art

[0002] In the steelmaking process, sintering is a key core link, and its role is to provide high-quality low-sulfur sintered ore for the ironmaking blast furnace. The sintering process is roughly divided into seven links from beginning to end, namely batching-mixing-laying-ignition-sintering-cooling-granulation. Among them, the cooling link is to recover the waste heat of the red-hot sintered ore through normal temperature air heat exchange, and use the waste gas after heat exchange to generate steam for power generation. Its operation quality directly affects the energy efficiency index of the entire sintering process.

[0003] The existing sintering cooling process flow diagram is as follows Figure 1 As shown in the figure: the sintering machine trolley full of sintered ore begins to turn over after entering the tail cover, so that the sintered ore layer inside is poured out as a whole, the material layer falls and is broken by the single roller crusher, and the broken pieces enter the ring cooler through the material discharge chute for air blast cooling. At the same time, the empty trolley after pouring out the material layer returns to the sintering machine head position under the action of the large gear, ready for the next cycle of material loading.

[0004] The material layer reaction in the sintering machine trolley is as follows Figure 2 and 3 As shown: After laying and ignition, the sintered material layer is as follows: Figure 2 As shown in the figure, a uniform high-temperature zone is formed on the surface; and with the lower exhaust, when the sintering machine trolley reaches the tail position, the high-temperature zone has moved down from the upper part of the material layer to the bottom of the material layer. At this time, the upper part of the high-temperature zone is all sintered finished ore, most of which has a temperature below 50°C and accounts for about 3 / 4 of the entire sintering material layer. Figure 3 shown.

[0005] With the introduction of my country's dual carbon strategy, the steel industry has an increasingly obvious demand for energy conservation and carbon reduction. Reducing process energy consumption and process carbon emissions through extreme energy efficiency methods has become a hot topic in the industry. The current sintering ore production process has low efficiency in waste heat utilization during cooling and there is energy waste, as follows:

[0006] 1. Cold ore and hot ore are mixed together for cooling, and the exhaust gas temperature is low: Due to the cooling of the ore in the tail car of the sintering machine in the prior art, the ore is first poured down as a whole, falls on the single roller crusher for crushing, and then enters the ring cooler for blast cooling. The disadvantage of this method is that the upper and lower material layers in the sintering car are not separated, resulting in the cold ore on the upper layer and the hot ore on the lower layer being mixed together and entering the cooler for cooling. The exhaust gas temperature after cooling is low, and the heat utilization efficiency is poor;

[0007] 2. Serious waste of power consumption of cooling fans: As mentioned above, since the cold ore and hot ore of the sintering machine are mixed together and enter the cooler for cooling, the material volume is large and the wind resistance is high, which leads to unnecessary waste of power consumption of cooling fans. Utility Model Content

[0008] In view of the defects existing in the above-mentioned prior art, the utility model proposes an arc plate type sintering machine layered unloading and cooling device.

Therefore, the arrangement of the dividing plate device can realize the high and low temperature layered unloading of the sintered ore. After sintering is completed, the low temperature material located on the upper layer of the sintering trolley is discharged from above the dividing plate and the upper material layer drainage plate, and the high temperature material located on the lower layer of the sintering trolley is discharged from below the dividing plate and the upper material layer drainage plate, thereby realizing the high and low temperature layered unloading and cooling of the sintered material layer, and then realizing the significant increase in the exhaust gas temperature after cooling the material, and greatly reducing the power consumption of the cooling fan.

[0009] According to the implementation scheme of the utility model, a layered material discharging cooling device for an arc plate type sintering machine is provided.

The device also comprises a dividing plate device arranged at the tail of the sintering machine. The dividing plate device comprises a dividing plate and an upper material layer drainage plate. Among them, one end of the dividing plate is connected to the discharge port on the sintering trolley entering the tail of the sintering machine, and corresponds to the high and low temperature layering position of the sintered ore in the sintering trolley. The other end of the dividing plate is tilted downward and connected to the upper material layer drainage plate arranged below. The other end of the upper material layer drainage plate is tilted downward and connected to the finished product trolley arranged below.

[0011] In the utility model, the material dividing plate device also includes an upper rotating shaft, an upper rotating motor, an upper bearing plate, an upper lifter, and an upper lifting motor. Among them, the upper rotating shaft is arranged between the material dividing plate and the upper material layer drainage plate, and the material dividing plate is connected to the upper material layer drainage plate through the upper rotating shaft. The upper rotating motor is connected to the upper rotating shaft. The upper bearing plate is fixedly mounted on the tail cover. One end of the upper lifter is connected to the upper rotating shaft, and the other end is connected to the upper bearing plate. The upper lifting motor is connected to the upper lifter.

[0012] Preferably, the device further comprises a lower material layer drainage device and a discharge hopper. The lower material layer drainage device is arranged on the side of the large gear and is located below the upper material layer drainage plate. The discharge hopper is arranged below the lower material layer drainage device and is connected to the discharge port of the lower material layer drainage device.

[0013] In the utility model, the lower material layer drainage device includes a straight plate section 1 and a straight plate section 2. The straight plate section 1 is arranged on the side of the large gear and is tilted downwardly and connected to the straight plate section 2 arranged below. The other end of the straight plate section 2 is tilted downwardly and connected to the discharge hopper.

[0014] In the utility model, the lower material layer drainage device also includes a lower layer rotating shaft, a lower layer rotating motor, a lower layer bearing plate, a lower layer lifter, and a lower layer lifting motor. Among them, the lower layer rotating shaft is arranged between the first straight plate section and the second straight plate section, and the first straight plate section is connected to the second straight plate section through the lower layer rotating shaft. The lower layer rotating motor is connected to the lower layer rotating shaft. The lower layer bearing plate is fixedly mounted on the tail cover. One end of the lower layer lifter is connected to the lower layer rotating shaft, and the other end is connected to the lower layer bearing plate. The lower layer lifting motor is connected to the lower layer lifter.

[0015] Preferably, the angle between the upper material layer guide plate and the horizontal plane is less than or equal to the angle between the second straight plate section and the horizontal plane.

[0016] In the present invention, the dividing plate of the dividing plate device is arc-shaped. Preferably, the curvature of the dividing plate is consistent with the profile of the large gear.

[0017] Preferably, the device further comprises a temperature detection device, which is arranged at the tail of the sintering machine and located in the tail cover.

[0018] In the utility model, the device further comprises a cooler arranged below the discharge hopper.

[0019] In the utility model, the device further comprises a crushing device arranged between the discharge port of the lower material layer drainage device and the discharge hopper.

[0020] In view of the problem of low cooling exhaust gas temperature and serious power consumption of cooling fan caused by the crushing and cooling of cold ore located on the upper layer of the sintering trolley and hot ore located on the lower layer after sintering in the prior art, the utility model proposes an arc plate type sintering machine layered unloading cooling device. The device adds a dividing plate device at the tail of the sintering machine, and the dividing plate device includes a dividing plate connected to the unloading port of the sintering trolley and an upper material layer drainage plate connected to the dividing plate, and the dividing plate is arranged corresponding to the high and low temperature layering position of the sintered ore in the sintering trolley. Therefore, the setting of the dividing plate device can realize the high and low temperature layered unloading of sintered ore, wherein the low temperature material located on the upper layer of the sintering trolley after sintering is completed is discharged from above the dividing plate and the upper material layer drainage plate, and the temperature of this part of the material is relatively low, and it directly enters the finished product trolley, and there is no need to enter the cooling machine for cooling operation later; while the high temperature material located on the lower layer of the sintering trolley is discharged from below the dividing plate and the upper material layer drainage plate, and the temperature of this part of the material is relatively high, and it enters the cooling machine for cooling later. Therefore, the use of the utility model can realize high and low temperature layered cooling of the sintering material layer, that is, the materials that need to be cooled subsequently are all high-temperature materials, and are basically not mixed with low-temperature materials. Therefore, the sintering ore processing volume of the cooling process is greatly reduced. Compared with the existing technology, the temperature of the exhaust gas after cooling is significantly improved, the power consumption of the cooling fan will also be greatly reduced, and the energy consumption index will be significantly improved.

[0021] In the utility model, the material dividing plate device also includes an upper rotating shaft, an upper rotating motor, an upper bearing plate, an upper lifting device and an upper lifting motor. Among them, the upper rotating shaft is arranged between the material dividing plate and the upper material layer drainage plate, and is used to connect the material dividing plate and the upper material layer drainage plate, and drive the material dividing plate and the upper material layer drainage plate to realize free rotation. The upper rotating motor is connected to the upper rotating shaft, and provides driving force for the upper rotating shaft to drive the rotation of the material dividing plate and the upper material layer drainage plate. The upper bearing plate is fixedly mounted on the tail cover, and the upper rotating shaft is suspended and fixed inside the tail cover by the upper lifting device. The setting of the upper lifting device can realize the up and down movement of the upper rotating shaft and drive the material dividing plate and the upper material layer drainage plate to realize up and down movement. The upper lifting motor is connected to the upper lifting device, and provides driving force for the upper rotating shaft to drive the material dividing plate and the upper material layer drainage plate to realize up and down movement. Through the driving action of the upper rotating motor and the upper lifting motor, the distribution plate and the upper material layer drainage plate can be rotated and moved up and down, that is, the angle and position adjustment of the distribution plate and the upper material layer drainage plate can be achieved, so that the high and low temperature layered unloading of the sintering material layer (that is, sintered ore) can be more accurately achieved.

[0022] The utility model also includes a lower material layer drainage device. Different from the dividing plate device, the lower material layer drainage device is arranged relatively downward, below the upper material layer drainage plate of the dividing plate device. The lower material layer drainage device includes a straight plate section one arranged on the side of the large gear and a straight plate section two connected to the straight plate section one. The straight plate section one and the straight plate section two are arranged to be inclined downward, and the inclination angles of the two can be the same or different. The arrangement of the lower material layer drainage device provides a discharge channel for the high-temperature material discharged from the bottom of the dividing plate device, which can prevent the discharged high-temperature material from being too dispersed, thereby preventing the lower layer high-temperature material from being mixed into the low-temperature material during the discharge process, and also facilitates all high-temperature materials to enter the cooler for cooling after the crushing process.

[0023] Preferably, the lower material layer drainage device also includes a lower rotating shaft, a lower rotating motor, a lower bearing plate, a lower lifting device, and a lower lifting motor. Among them, the lower rotating shaft is arranged between the first section of the straight plate and the second section of the straight plate, and is used to connect the first section of the straight plate and the second section of the straight plate, and drive the first section of the straight plate and the second section of the straight plate to realize free rotation. The lower rotating motor is connected to the lower rotating shaft to provide a driving force for the lower rotating shaft to drive the first section of the straight plate and the second section of the straight plate to rotate. The lower bearing plate is fixedly mounted on the tail cover, and the lower rotating shaft is suspended and fixed inside the tail cover by the lower lifting device. The setting of the lower lifting device can realize the up and down movement of the lower rotating shaft and drive the first section of the straight plate and the second section of the straight plate to realize up and down movement. The lower lifting motor is connected to the lower lifting device to provide a driving force for the lower rotating shaft to drive the first section of the straight plate and the second section of the straight plate to move up and down. Through the driving action of the lower rotating motor and the lower lifting motor, the straight plate section one and the straight plate section two can be rotated and moved up and down, that is, the angle and position adjustment of the straight plate section one and the straight plate section two can be achieved, so as to better guide the discharge of the high-temperature material located at the lower layer of the sintering trolley after sintering is completed.

[0024] In order to further prevent the high-temperature materials located at the lower layer of the sintering trolley from being mixed into the upper layer low-temperature materials during the discharge process after sintering is completed, the utility model sets the angle between the upper material layer guide plate and the horizontal plane to be less than or equal to the angle between the second straight plate section and the horizontal plane. In order to ensure smooth discharge of the lower layer high-temperature materials, the angle between the upper material layer guide plate and the horizontal plane can also be set to be less than or equal to the angle between the first straight plate section and the horizontal plane.

[0025] Since the materials in the sintering trolley are turned over and unloaded around the large gear at the tail of the sintering machine after sintering, the utility model sets the dividing plate of the dividing plate device to be arc-shaped. Preferably, the curvature of the arc-shaped dividing plate is consistent with the contour of the large gear.

[0026] Generally speaking, the temperature of the sintered finished ore is mostly below 50℃, and its volume accounts for about 3 / 4 of the whole sintered material layer. Figure 3 As shown, the high and low temperature stratification positions of the sintered ore are Figure 3 The boundary position between the fired cold material layer and the sub-high temperature material layer. In other words, based on experience, the high and low temperature layer positions of the sintered ore in the sintering trolley after sintering can be roughly determined. The utility model also sets a temperature detection device at the tail of the sintering machine to detect the temperature distribution data of the material layer of the sintered ore in the sintering trolley during unloading, so as to more accurately determine the high and low temperature layer positions of the sintered ore and realize accurate layered unloading.

[0027] When using the device of the utility model, the position of the partition interface of the high and low temperature areas in the sintered material layer is determined based on experience or the temperature distribution data of the material layer in the unloading trolley detected by the temperature detection device, and this position is used as the control basis. The upper rotating motor and the upper lifting motor are used to control the dividing plate device to rotate and move up and down, so that the dividing plate is aligned with the high and low temperature partition interface of the sintered material layer in the unloading trolley, so that the sintered material layer is cut by the dividing plate during the unloading process, and the upper low-temperature material layer enters the finished product trolley after passing through the dividing plate and the upper material layer drainage plate, skipping the cooling link and directly entering the finished product ore bin. At the same time, the lower rotating motor and the lower lifting motor control the lower material layer drainage device to rotate and move up and down, so that the straight plate section 1 and the straight plate section 2 can better provide a discharge channel for the lower high-temperature material layer. After passing through the straight plate, the lower high-temperature material layer collides with the crushing device (such as a single-roll crusher) and is crushed and then enters the cooler (such as a ring cooler) to implement blast cooling.

[0028] Compared with the prior art, the utility model has the following beneficial effects:

[0029] 1. High exhaust gas temperature: Due to the adoption of the technology of the utility model, the sintering material layer is discharged in layers according to high and low temperatures, so all the materials entering the cooler are high-temperature materials. Compared with the existing technology, the average material temperature can be increased by more than 200%, so the exhaust gas temperature after cooling and heat exchange will also be significantly increased, and the efficiency of generating steam and power generation at the back end will be significantly enhanced.

[0030] 2. Low power consumption of cooling fan: Due to the adoption of the technology of the utility model, all materials entering the cooler are high-temperature materials that actually need to be cooled, and there is no or very little low-temperature materials that do not need to be cooled mixed in. The processing capacity of the cooler is significantly reduced, so the power consumption of the cooling fan will be greatly reduced compared with the existing technology, and the energy efficiency index will be significantly improved.

[0031] In summary, the new technology of the utility model effectively solves the defects and shortcomings of the existing technology without causing other negative effects, and has low investment and operating costs. It can be expected to have high application value in the future market. BRIEF DESCRIPTION OF THE DRAWINGS
