Description

Technical Field

[0001] The utility model relates to a sintering cooling device, in particular to a layered material discharging cooling device for a broken column type sintering machine, 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 a layered unloading and cooling device for a sintering machine with a breaking column. The device is provided with a wind cushion-type breaking column below the unloading position at the tail of the sintering machine, and the wind cushion-type breaking column includes a column body and a unloading hopper, wherein the column body is vertically arranged in the unloading hopper, and the space in the unloading hopper is divided into a first unloading chamber and a second unloading chamber along the running direction of the sintering machine, and the setting position of the column body corresponds to the high and low temperature layering position of the sintered ore in the sintering trolley during unloading. When the sintered ore is unloaded from the sintering trolley after sintering, it collides with the column body of the wind cushion-type breaking column, and is divided into a high-temperature ore layer and a low-temperature ore layer by the column body, and enters the first unloading chamber and the second unloading chamber of the unloading hopper respectively, that is, the setting of the wind cushion-type breaking column can realize the high and low temperature layered unloading of the sintered ore, thereby realizing the layered unloading and cooling of the sintered material layer, so that the exhaust gas temperature after cooling the material is significantly improved, and the power consumption of the cooling fan is greatly reduced.

[0009] At the same time, the column is also provided with a vertical air duct, an air inlet connected to the air duct, and an air nozzle arranged on the upper part of the air duct. During the unloading process of the sintered ore, the high-pressure air entering from the air inlet is ejected through the air duct and the air nozzle, forming a layer of high-pressure air cushion on the upper surface of the column, thereby protecting the column.

[0010] According to the implementation scheme of the utility model, a layered material discharging and cooling device for a broken column type sintering machine is provided.

[0011] A breaking column type sintering machine layered unloading cooling device, the device includes a sintering trolley, a tail cover arranged at the tail of the sintering machine, and an air cushion type breaking column arranged below the tail unloading position. The air cushion type breaking column includes a column body and a discharge hopper. The column body is vertically arranged in the discharge hopper, and divides the space in the discharge hopper into two chambers along the running direction of the sintering machine, namely a first discharge chamber and a second discharge chamber. The setting position of the column body corresponds to the high and low temperature layering position of the sintered ore in the sintering trolley during unloading. The column body is also provided with a vertical air duct, an air inlet connected to the air duct, and an air nozzle arranged at the upper part of the air duct.

[0012] In the utility model, the wind cushion type material breaking column also includes a walking track, a walking device, and a walking motor. The walking track passes through the column and is arranged on both sides of the upper part of the lower hopper along the running direction of the sintering machine. The walking device is arranged on the walking track and connected to the column. The walking motor is connected to the column.

[0013] Preferably, a partition is provided in the air duct at a position lower than the height of the air inlet.

[0014] Preferably, the air duct is provided with a plurality of air jets, which are evenly distributed on the top and / or upper part of the side wall of the air duct.

[0015] In the utility model, the device also includes a tail poking device arranged above the tail unloading position. The tail poking device includes a load-bearing member, a poking rod, and a poking motor. Among them, the load-bearing member is fixedly mounted on the tail cover. The poking rod is arranged on the load-bearing member and passes through the load-bearing member. The poking motor is connected to the load-bearing member, and drives the poking rod to move up and down through the load-bearing member.

[0016] Preferably, the poking rod comprises a high-temperature poking rod and a low-temperature poking rod. The high-temperature poking rod and the low-temperature poking rod are sequentially arranged on the load-bearing member and correspond to the positions of the high-temperature material layer and the low-temperature material layer in the sintering trolley during unloading. The poking motor drives the high-temperature poking rod and the low-temperature poking rod to move up and down.

[0017] In the utility model, the device also includes an embedded plate arranged in the sintering trolley. The embedded plate includes a plate body and a positioning bolt. The plate body is arranged in parallel in the sintering trolley, and the setting height of the plate body corresponds to the high and low temperature layering position of the sintered ore in the sintering trolley after sintering. The positioning bolt is connected to the plate body and installed on the side wall of the sintering trolley. The plate body is provided with evenly distributed flower holes.

[0018] Preferably, screw holes are provided at different heights on the side wall of the sintering trolley, and positioning bolts pass through the screw holes to connect with the plate body.

[0019] Preferably, the shape of the flower hole is circular or elongated oval.

[0020] In the utility model, the top of the column is configured as a pointed structure.

[0021] 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.

[0022] In the utility model, the device further comprises a cooling machine and a finished product trolley arranged below the unloading hopper, wherein the cooling machine is arranged below the first unloading chamber, and the finished product trolley is arranged below the second unloading chamber.

[0023] In view of the problems in the prior art that the cold ore located on the upper layer of the sintering trolley and the hot ore located on the lower layer are crushed and cooled together after sintering, resulting in low cooling exhaust gas temperature and serious power consumption of the cooling fan, the utility model proposes a layered unloading cooling device for a sintering machine with a breaking column. The device is provided with a wind cushion type breaking column below the unloading position at the tail of the sintering machine. The wind cushion type breaking column includes a column body and a unloading hopper. The unloading hopper is closely connected with the tail cover. The column body is vertically arranged in the unloading hopper, and the space in the unloading hopper is divided into a first unloading chamber and a second unloading chamber along the running direction of the sintering machine. The setting position of the column body corresponds to the high and low temperature layering position of the sintered ore in the sintering trolley during unloading. When the sintered ore is unloaded from the sintering trolley after sintering, it collides with the column body of the wind cushion type breaking column, and is divided into a high temperature ore layer and a low temperature ore layer by the column body, and enters the first unloading chamber and the second unloading chamber of the unloading hopper respectively. Among them, the temperature of the part of the material entering the second unloading chamber is relatively low, and it directly enters the finished product trolley without entering the cooler for cooling operation; while the temperature of the part of the material entering the first unloading chamber is relatively high, and it enters the cooler for cooling later. Therefore, the setting of the wind cushion type breaking column can realize the high and low temperature layered unloading of sintered ore, and then realize the layered unloading and cooling of the sintered material layer, so that the exhaust gas temperature after cooling the material is significantly increased, and the power consumption of the cooling fan is greatly reduced.

[0024] At the same time, the column is also provided with a vertical air duct, an air inlet connected to the air duct, and an air jet arranged at the upper part of the air duct. During the unloading process of the sintered ore, the high-pressure wind entering from the air inlet is ejected through the air duct via the air jet, forming a layer of high-pressure wind cushion on the upper surface of the column, thereby protecting the column. Preferably, the utility model also sets a partition in the air duct at a position lower than the height of the air inlet, and forms an air inlet and outlet opening loop through the partition, the air inlet, the air duct, and the air jet. The air duct is located inside the column, and a plurality of air jets are evenly arranged at the top and / or the upper part of the side wall of the air duct, and each air jet is connected to the air duct, so that the high-pressure wind is ejected through the air duct via multiple air jets, forming a high-pressure wind cushion on the upper surface of the column, protecting the column and extending the service life of the column. In addition, the air inlet is also provided with a valve, through which the air volume entering the air duct can be adjusted, and the best air cushion protection is provided for the column without affecting the layered unloading of the sintered ore.

[0025] In the utility model, the wind cushion type breaking column also includes a walking track, a walking device and a walking motor. Among them, the walking track passes through the column and is closely connected with the lower hopper, and is installed on both sides of the upper part of the lower hopper along the running direction of the sintering machine. The walking device is arranged on the walking track and connected to the column. The walking device can move back and forth in the horizontal direction on the walking track, and drive the column to move in the horizontal direction. The walking motor is connected to the column to provide driving force for the movement of the walking device and the column. Through the driving action of the walking motor, the position adjustment of the column in the running direction of the sintering machine can be realized, so that the high and low temperature layered discharge of the sintering material layer (i.e., sintered ore) can be more accurately realized.

[0026] The utility model also includes a tail poking device arranged above the tail unloading position of the sintering machine. The tail poking device includes a load-bearing member, a poking rod and a poking motor. Among them, the load-bearing member is closely connected to the tail cover and fixedly mounted on the tail cover. The poking rod is connected to the load-bearing member and can move freely up and down through the transmission device inside the load-bearing member, and its purpose is to poke down the material that may be stuck during the unloading process. Preferably, the poking rod is divided into two, namely, a high-temperature poking rod and a low-temperature poking rod, which respectively correspond to the high-temperature material layer and the low-temperature material layer in the sintering material layer. The poking motor is connected to the load-bearing member, and provides driving force for the up and down movement of the poking rod through the transmission device provided in the load-bearing member.

[0027] The utility model also provides an embedded plate in the sintering trolley. The embedded plate includes a plate body and positioning bolts. During production, the plate body is embedded and fixed to a certain height in the material layer of the sintering trolley by the positioning bolts. During material distribution, the mixed material above the plate body will flow to the bottom of the plate body through the flower holes evenly opened on the plate body. At the same time, the material layer is divided into an upper layer and a lower layer by the plate body. The purpose is to artificially divide the sintered ore into a high-temperature layer and a low-temperature layer. Screw holes are opened at different heights on the side of the sintering machine trolley, and the embedded plate can freely change the installation height. The opening shape of the flower holes and their structural form are not limited, and they can realize the flow of the sintering material from top to bottom and uniform distribution. For example, the flower holes can be circular, elongated, elliptical, etc., and the structural form of the flower holes can be Fig.10 , Fig.11 , Fig.12 or Fig.13 in the above mentioned form or in any form other than that.

[0028] The utility model eliminates the single-roll crusher in the prior art. The purpose of doing so is to make the sintered ore layer unloaded from the sintering trolley relatively more integrated, so that it can collide with the column of the wind cushion type crushing column during unloading, making it easier to break the material into layers. In order to enhance the stratification effect of the wind cushion type crushing column on the unloaded sintered ore, the present application sets the top of the column as a pointed structure. It should be noted that since the wind cushion type crushing column in the present application is located below the tail unloading device, the flipping unloading method of the existing sintering trolley may not be able to achieve the correspondence between the high-temperature material layer and the low-temperature material layer and the first unloading chamber and the second unloading chamber of the unloading hopper. Therefore, the present application can open the front side wall of the sintering trolley in the running direction of the sintering machine for unloading. At this time, the front side wall of the sintering trolley is movably connected to the entire sintering trolley. Preferably, a driving device is connected to the front side wall of the sintering trolley. When the sintering trolley enters the tail of the sintering machine and needs to unload, the driving device is started to open the front side wall of the sintering trolley for unloading, thereby ensuring that the sintered ore layer is divided into a high-temperature ore layer and a low-temperature ore layer by the column during unloading, thereby realizing high and low temperature layered unloading of the sintered ore.

[0029] 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.

[0030] When using the device of the utility model, the temperature distribution data of the material layer in the unloading trolley detected by the experience or temperature detection device is analyzed to determine the partition interface position of the high and low temperature areas in the sintering material layer, and this position is used as the control basis to calculate the height position of the embedded plate, the horizontal position of the poking rod of the tail poking device and the horizontal position of the column of the wind cushion type breaking column; at the same time, the setting height of the embedded plate is adjusted by the positioning bolts at the head inspection port, the horizontal position of the poking rod is adjusted by adjusting the poking motor, and the horizontal position of the column is adjusted by adjusting the walking motor, so as to finally realize the one-to-one determination of the positions of each structure. The fired sintered ore layer is unloaded from the sintering trolley and divided into two layers, high-temperature and low-temperature, by the embedded plate embedded in the sintered ore layer. During the unloading process of the sintering trolley in the tail cover, the tail poking device controls the poking rod to periodically descend, thereby poking out the material in the sintering trolley. The poked material falls and hits the column of the pointed structure, and is further divided into a high-temperature ore layer and a low-temperature ore layer. The high-temperature ore layer falls from the upstream side of the column into the first discharge chamber of the discharge hopper and finally falls into a cooler (such as a ring cooler) for blast cooling, and the low-temperature ore layer falls from the downstream side of the column into the second discharge chamber of the discharge hopper and finally falls into the finished product trolley and is directly transported to the finished product bin.

[0031] Compared with the prior art, the utility model has the following beneficial effects:

[0032] 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.

[0033] 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.

[0034] 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
