Description

Technical Field

[0001] The utility model relates to the technical field of sintering equipment, in particular to a sintering dehumidification system. Background Art

[0002] Sintering production is an important part of the production process of the steel industry and is the basic condition for ensuring the normal production of blast furnace ironmaking. In the sintering process, one of the most important links is the series of physical and chemical reactions of the materials on the sintering machine trolley. During the process of mixed material exhaust sintering, five areas with different properties will appear along the entire material layer height. The top layer is the sintering zone, and the lower layer is the combustion zone, preheating zone, drying zone and over-wet zone (or original mixed material zone). As the sintering time increases, each zone gradually disappears, leaving only the sintering zone. Among them, the exhaust gas coming down from the drying zone contains a large amount of water vapor. When these exhaust gases containing water vapor encounter the cold material at the bottom, the temperature suddenly drops. When the temperature of these exhaust gases containing water vapor drops below the temperature of condensation into water droplets - the dew point temperature (52℃~65℃), the water vapor changes from gas to liquid, causing the moisture content of the lower mixed material to increase continuously and form an over-wet zone. The formation of the over-wet zone will deteriorate the air permeability of the material layer. Therefore, how to reduce the occurrence of over-humidification during the sintering process to improve the sintering quality has become a technical problem that needs to be solved urgently.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Please refer to Figure 1 and Figure 2As shown, a sintering dehumidification system is provided in an embodiment of the utility model, which includes a sintering device 100 and an exhaust assembly 200, the sintering device 100 includes a sintering trolley, a partition 110 arranged on the sintering trolley, and a breathable structure arranged on the partition 110; the exhaust assembly 200 includes an exhaust structure 210 arranged on one side of the sintering trolley, the exhaust structure 210 includes a plurality of air ducts 211, and a plurality of exhaust main pipes 212 corresponding to and connected to the air ducts 211, the air duct 211 has an exhaust port 213 arranged facing the breathable structure, and the exhaust ports 213 are sequentially arranged along the extension direction of the sintering trolley and connected to the breathable structure.

[0039] On the whole, when the sintering dehumidification system is used, a breathable structure is provided on the partition 110 of the sintering trolley, and the two sides of the partition 110 can be connected through the breathable structure, so as to facilitate the subsequent extraction of water vapor in the material on the sintering trolley. In addition, an exhaust structure 210 is provided on one side of the sintering trolley, and the exhaust ports 213 of the multiple air ducts 211 in the exhaust structure 210 are arranged in sequence along the extension direction of the sintering trolley, wherein the air duct 211 itself does not have the ability to exhaust air, so the air duct 211 can be connected to the exhaust main pipe 212, and the exhaust main pipe 212 is used to provide an exhaust power source. Each exhaust port 213 can be connected to the breathable structure, and then the water vapor in the material on the sintering trolley can enter the air duct 211 along the exhaust port 213 to achieve a dehumidification effect, reduce the humidity of the material, and thus help improve the subsequent sintering quality.

[0040] The designer can adjust the specific model structure of the sintering device 100 according to the use requirements, and no specific restrictions are made here. Preferably, the starting position of the exhaust assembly 200 is the rear side of the igniter of the sintering device 100, and the end position of the exhaust assembly 200 is the front side of the single roller crusher at the tail of the sintering device 100.

[0041] In the implementation mode of the present utility model, Figure 1 In the illustrated embodiment, two groups of exhaust structures 210 are provided, and the two groups of exhaust structures 210 are respectively provided on both sides of the sintering trolley.

[0042] By providing two sets of exhaust structures 210, exhaust and dehumidification operations can be performed on both sides of the sintering trolley respectively by using the two sets of exhaust structures 210, which is beneficial to improving the dehumidification uniformity of the material and further improving the subsequent sintering quality of the material.

[0043] Furthermore, the exhaust pipe 212 may be arranged at the bottom of the sintering trolley, and the air duct 211 is connected to the exhaust pipe 212 located at the bottom of the sintering trolley, so that the exhaust power is provided by the exhaust pipe 212 .

[0044] In the implementation mode of the present utility model, Figure 2 , Figure 3 and Figure 4 In the embodiment shown, the area of ​​the air outlet 213 of each air duct 211 is gradually reduced along the transport direction of the sintering trolley. The designer can adjust the area of ​​each air outlet 213 according to the dehumidification needs, and no specific numerical value is imposed here.

[0045] By utilizing a plurality of air ducts 211 to exhaust and dehumidify the materials on the sintering trolley, the humidity of the materials downstream of the sintering trolley is gradually reduced, thereby eliminating the need to use constant power for dehumidification operations.

[0046] The utility model gradually reduces the area of ​​the exhaust ports 213 of each downstream air duct 211. On the one hand, the exhaust ports 213 with smaller areas can still achieve good exhaust and dehumidification effects. On the other hand, it is also beneficial to reduce the manufacturing cost of the device and the exhaust operation cost.

[0047] Furthermore, along the transport direction of the sintering trolley, the diameter of each air duct 211 is gradually reduced. The designer can adjust the diameter of each air duct 211 according to the use requirements, and no specific numerical value is limited here.

[0048] It can be seen from the above that as the humidity of the material on the sintering trolley decreases, the area of ​​the exhaust port 213 gradually decreases. Correspondingly, by gradually reducing the diameter of each air duct 211, each air duct 211 is matched with the exhaust port 213. This is beneficial to maintaining the suction power of each exhaust port 213, avoiding causing greater disturbance to the material, and improving the stability of the exhaust process.

[0049] The designer can adjust the shape of the air duct 211 according to the use requirements. For example, the cross section of the air duct 211 can be set to a circular, square or other shape, which is not specifically limited here. In addition, along the extension direction of the air duct 211, the air duct 211 can be set to a single cross-sectional shape or a composite cross-sectional shape.

[0050] In the implementation mode of the present utility model, Figure 3 and Figure 4 In the embodiment shown, the air inlets 213 are arranged in a flared manner, and the air inlets 213 are connected in sequence. By flaring the air inlets 213, the air inlets 213 can be better covered or roughly covered on the air permeable structure of the partition 110, thereby improving the air extraction effect.

[0051] Furthermore, by sequentially connecting the plurality of air intake ports 213, it is advantageous to eliminate the gaps between adjacent air intake ports 213 and to seal the gaps between adjacent air intake ports 213. Designers can adjust the sealing structure between adjacent air intake ports 213 according to usage requirements, and no specific limitation is made here.

[0052] The designer can adjust the specific shape of the air vent 213 according to the use requirements, and no specific limitation is made here. Preferably, the cross-sectional shape of the air vent 213 is rectangular. The rectangular air vent 213 is easy to process and manufacture, and can be better covered on the partition 110.

[0053] Along the transport direction of the sintering trolley, such as Figure 2 , Figure 3 and Figure 4 In the embodiment shown, a plurality of air ducts 211 exhaust and dehumidify the material on the sintering trolley, and cooperate with the sintering operation to continuously reduce the humidity of the material, especially along the height direction, the humidity of the upper layer of the material will be significantly reduced, so that only the lower layer of the material needs further exhaust and dehumidification.

[0054] In order to solve the above problems, in the implementation mode of the present utility model, Figure 2 , Figure 3 and Figure 4 In the illustrated embodiment, along the conveying direction of the sintering carriage, each air duct 211 is divided into a plurality of air duct sections, and the cross-sectional areas of the air outlets 213 of each air duct 211 in the same air duct section are the same.

[0055] By dividing each air duct 211 into a plurality of air duct sections, and making the cross-sectional area of ​​the air outlet 213 of each air duct 211 in the same air duct section the same, the air ducts 211 in each air duct section have different cross-sectional areas, and using air ducts 211 with different cross-sectional areas to achieve the dehumidification effect for materials at different heights, on the one hand, using the air outlet 213 with a smaller area can still achieve a good dehumidification effect, and on the other hand, it is also beneficial to reduce the manufacturing cost of the device and the running cost of the exhaust. Among them, the number of air ducts 211 in each air duct section can be one or more, and there is no specific limitation here.

[0056] In a specific embodiment, the plurality of air duct sections include a first air duct section 300 , which is disposed at the most upstream side of the sintering trolley, and the height of the air outlet 213 of the air duct 211 in the first air duct section 300 is the same as the height of the partition 110 .

[0057] The partition 110 can be fully covered by the first air duct section 300, so that the material in this part can be fully sucked, which significantly reduces the humidity of the material and improves the dehumidification effect.

[0058] Secondly, the multiple air duct sections include a second air duct section 400, which is arranged downstream of the first air duct section 300. The height of the air outlet 213 of the air duct 211 located in the second air duct section 400 is smaller than the height of the partition 110.

[0059] Due to the dehumidification effect of the first air duct section 300, the humidity in the material decreases, and with the sintering effect, the humidity of the upper layer of the material is significantly reduced. At this time, the upper layer of the material does not need to be dehumidified by dehumidification, so as to save resources.

[0060] The second air duct section 400 can continue to carry out targeted ventilation and dehumidification operations on the portion of the material with a higher moisture content, thereby further reducing the moisture content of the material, which is beneficial to improving the subsequent sintering quality.

[0061] Furthermore, the multiple air duct sections include a third air duct section 500, which is arranged downstream of the second air duct section 400, and the height of the air exhaust port 213 of the air duct 211 located in the third air duct section 500 is smaller than the height of the air exhaust port 213 of the air duct 211 located in the second air duct section 400.

[0062] Due to the dehumidification effect of the second air duct section 400, the humidity in the material is further reduced. Through the third air duct section 500, targeted dehumidification operations can continue to be performed on the part of the material with a higher moisture content, which is beneficial to further reduce the moisture content in the material.

[0063] Furthermore, the multiple air duct sections include a fourth air duct section 600, which is arranged downstream of the third air duct section 500, and the height of the air exhaust port 213 of the air duct 211 located in the fourth air duct section 600 is smaller than the height of the air exhaust port 213 of the air duct 211 located in the third air duct section 500.

[0064] Due to the dehumidification effect of the third air duct section 500, the humidity in the material is further reduced. Through the fourth air duct section 600, targeted dehumidification operations can continue to be performed on the part of the material with a higher moisture content, which is beneficial to further reduce the moisture content in the material.

[0065] In the implementation mode of the present utility model, Figure 4 In the illustrated embodiment, the height of the exhaust port 213 of the air duct 211 located in the second air duct section 400 is approximately one-third and one-fourth of the height of the partition 110; and / or the height of the exhaust port 213 of the air duct 211 located in the third air duct section 500 is approximately one-half of the height of the partition 110; and / or the height of the exhaust port 213 of the air duct 211 located in the fourth air duct section 600 is approximately one-quarter of the height of the partition 110.

[0066] Preferably, the height of the exhaust port 213 of the air duct 211 located in the second air duct section 400 is approximately one-third of the height of the partition 110; the height of the exhaust port 213 of the air duct 211 located in the third air duct section 500 is approximately one-half of the height of the partition 110; the height of the exhaust port 213 of the air duct 211 located in the fourth air duct section 600 is approximately one-quarter of the height of the partition 110.

[0067] Of course, in other feasible embodiments, designers can adjust the height of each air outlet 213 according to usage requirements, and no specific numerical limit is imposed herein.

[0068] Furthermore, the designer can adjust the shape and diameter of each air duct 211 according to the use requirements, and no specific numerical limit is imposed here. For example, the pipe where the air duct 211 in each air duct section is connected to the exhaust main pipe 212 is changed from a square pipe to a Furthermore, the connection between the air duct 211 and the exhaust main pipe 212 can be welded by opening a hole, and the quality of the weld is ensured and ultrasonic testing is performed to ensure that there is no air leakage.

[0069] In the embodiment of the utility model, a control mechanism 214 is provided on the air duct 211. Specifically, the control mechanism 214 is a control valve. Designers can adjust the specific model of the control valve according to the use requirements, and no specific restrictions are made here. Preferably, the control valve is a butterfly valve.

[0070] In a feasible embodiment, a butterfly valve is installed on the circular pipe section of the air duct 211, and the butterfly valve can be installed on the plane of the sintering trolley, so as to facilitate manual operation. Of course, the butterfly valve can also be controlled by a PLC controller, or on-site control.

[0071] In the embodiment of the utility model, a sealing structure is also included between the sintering trolley and the exhaust assembly 200, and the sealing structure is an oil-free flexible sealing structure. By adopting the oil-free flexible sealing structure, there is no need to add lubricating oil during use, saving lubricating oil costs, and avoiding the generation of smoke due to the combustion of lubricating oil by heat, thereby protecting the environment.

[0072] In the embodiment of the present utility model, the sealing structure includes a dynamic seal provided on the sintering trolley and a static seal provided on the exhaust assembly 200 , and the dynamic seal and the static seal are sealed to each other.

[0073] Specifically, the dynamic seal includes flexible sealing plates arranged on both sides of the sintering trolley, and the static seal includes a fixed beam connecting each air duct 211 and a fixed slideway arranged on the fixed beam. The flexible sealing plate and the fixed slideway are pre-tightened for sealing.

[0074] Furthermore, the flexible sealing plate is formed by a rubber material, and the fixed slideway is formed by a carbon steel plate. Preferably, the rubber material is a composite wear-resistant and high-temperature resistant rubber.

[0075] Among them, the flexible sealing plate can be fixed on both sides of the sintering trolley by bolts. After the flexible sealing plate is installed, it is pre-tightened and fitted with the fixed slideway on the fixed beam by its own material characteristics, so that the fixed slideway wears very little when the sintering trolley is running, and the service life is relatively long. It only needs to replace the flexible sealing plate regularly. In addition, the flexible sealing plate is installed on the sintering trolley, and the replacement process will not affect the sintering operation and is easy to operate.

[0076] In the embodiment of the utility model, the partition 110 is formed by a grate structure, and the grate structure is hollowed out to form a breathable structure. Designers can adjust the specific shape and structure of the grate structure according to the use requirements, and no specific restrictions are made here. Preferably, the grate structure is a grate plate.

[0077] Of course, in other feasible embodiments, designers can adjust the structure of the partition 110 according to usage to form a breathable structure, and no specific limitation is made here.
