Description

[0002] Briquettes are a kind of main raw materials used in metallurgical industry, which are obtained by screening and processing the raw ore with a certain particle size after mining. In the mining process, water is often used to suppress dust, and the dust formed in the mining process will adhere to the surface of the ore after being soaked in water, and is difficult to be removed by screening, so a large amount of powder will be brought into the metallurgical reduction process, which will eventually cause the deterioration of the permeability of the furnace charge.

[0003] In the related art, although a powerful screening device is configured in the production process, the strong adhesion of the water-containing dust makes it difficult to effectively separate the ore and the powder on the surface thereof. Meanwhile, briquettes are directly used as a kind of main raw material, which generally only stays in the raw material warehouse of the metallurgical furnace and the storage yard. The storage yard has a large storage capacity and can achieve long-term storage.

[0026] Embodiments: Please refer to Figures 1-17 The briquette drying device in the preferred embodiment of the present application can realize efficient drying of the briquettes, fully remove the moisture on the briquettes, thereby reducing the powder adhesion on the briquettes, and further greatly reducing the powder rate into the furnace.

[0027] Specifically, as shown in Figures 1-17 In the preferred embodiment of the present application, the briquette drying device dries the briquettes by means of the hot air in the hot air pipeline 604. The briquette drying device comprises a drying mechanism 3 and an air supply and exhaust mechanism 6.

[0028] The drying mechanism 3 comprises at least two drying members 1 arranged in sequence along the vertical direction. The drying member 1 comprises a frame body 101 extending along the vertical direction, a first evaporation plate 103 and a second evaporation plate 112. The frame body 101 comprises a drying channel 102 extending along the vertical direction, and the top opening of the drying channel 102 is a drying feeding port, so as to facilitate the briquettes to enter the drying channel 102 from the drying feeding port for drying. Meanwhile, the first evaporation plate 103 and the second evaporation plate 112 are arranged in sequence and staggered in the longitudinal direction in the drying channel 102, so as to form a plurality of drying spaces arranged in sequence in the drying channel 102.

[0029] The first evaporation plate 103 is provided with a through first evaporation air duct 104 in the transverse direction, and the second evaporation plate 112 is provided with a through second evaporation air duct 111 in the transverse direction. At least one drying hole 105 is arranged on the two side walls of the first evaporation plate 103 and the second evaporation plate 112, so that the hot air in the first evaporation air duct 104 and the second evaporation air duct 111 can flow into the drying space from the drying hole 105, thereby realizing effective drying of the briquettes in the drying space.

[0030] Meanwhile, a first opening 113 communicating with the first evaporation air duct 104 is formed on the first side wall of the frame body 101, and correspondingly, a second opening 114 communicating with the second evaporation air duct 111 is formed on the second side wall of the frame body 101, so as to realize air supply and exhaust in the adjacent two first evaporation plates 103 and second evaporation plates 112 from the first opening 113 and the second opening 114 by the air supply and exhaust mechanism 6.

[0031] Further, the air supply and exhaust mechanism 6 comprises a first air duct 601, a second air duct 602, a switching chamber 605 and an exhaust duct 603.

[0032] The switching chamber 605 is respectively communicated with the first air duct 601, the second air duct 602, the exhaust duct 603 and the hot air duct 604. Meanwhile, a switching piece 606 is arranged in the switching chamber 605, so as to divide the switching chamber 605 into two spaces. Before and after the switching piece 606 is switched, the first air duct 601 is switched from being communicated with the exhaust duct 603 to being communicated with the hot air duct 604, while the second air duct 602 is switched from being communicated with the hot air duct 604 to being communicated with the exhaust duct 603. Alternatively, the first air duct 601 is switched from being communicated with the hot air duct 604 to being communicated with the exhaust duct 603, while the second air duct 602 is switched from being communicated with the exhaust duct 603 to being communicated with the hot air duct 604.

[0033] Meanwhile, the first air duct 601 is communicated with each first opening 113, and the second air duct 602 is communicated with each second opening 114. In actual use, the hot air duct 604 and the exhaust duct 603 communicated by the first air duct 601 and the second air duct 602 make the adjacent first evaporation plate 103 and the second evaporation plate 112 respectively in the air supply state and the air exhaust state, so as to form the drying air flow flowing along the longitudinal direction at both sides of the drying space, avoid the drying flue gas extending along the longitudinal direction from being discharged from the drying inlet, and further reduce the drying flue gas with dust being discharged to the outside of the drying equipment, so as to avoid the spread of the dust pollution of the flue gas.

[0034] Further, the switching piece 606 switches the ducts communicated by the first air duct 601 and the second air duct 602, and further switches the first evaporation plate 103 and the second evaporation plate 112 respectively in the air exhaust state and the air supply state, so as to realize the sufficient drying of the lump ore by the drying form of the circulating drying longitudinal air flow at both sides.

[0035] It is worth mentioning that, in the preferred embodiment of the present application, the vertical direction is the direction of the vertical or plumb horizontal plane. The extending direction of each evaporation plate is the transverse direction. The direction of the interval arrangement of each evaporation plate is the longitudinal direction, which is perpendicular to the transverse direction in the horizontal plane.

[0036] Further, as shown in FIG. 1, the air supply and exhaust mechanism 6 comprises a first air duct 601, a second air duct 602, a switching chamber 605 and an exhaust duct 603. Figures 10-15As shown in the preferred embodiment of this application, both the first evaporator plate 103 and the second evaporator plate 112 include a base plate 108 and a first side plate 106 and a second side plate 107 arranged in parallel. The tops of the first side plate 106 and the second side plate 107 are fixedly connected, while the base plate 108 is fixed in the region between the bottoms of the first side plate 106 and the second side plate 107, thereby forming a stable evaporation airflow channel between the first side plate 106, the second side plate 107, and the base plate 108.

[0037] More preferably, the tops of the first side plate 106 and the second side plate 107 deform towards each other, forming an arc-shaped plate structure on their tops. This creates sharp corners on the tops of the first side plate 106 and the second side plate 107, allowing the clumps to accurately enter the drying zone between the two adjacent evaporation ducts, ensuring that the hot air inside the evaporation plate can fully dry the clumps. Preferably, the tips of the sharp corners are formed with arc-shaped surfaces to reduce deformation caused by contact between the top of the evaporation plate and the clumps.

[0038] More specifically, several through holes are provided on the base plate 108 along the longitudinal direction so that the hot air in the evaporation duct can be blown onto the lumps after passing through the drying zone through the through holes on the base plate 108, thereby further improving the drying rate of the lumps.

[0039] More preferably, such as Figures 10-15 As shown in the preferred embodiment of this application, a plurality of drying holes 105 are arranged in an array on both the first side plate 106 and the second side plate 107. Preferably, adjacent rows of drying holes 105 are staggered to improve the uniformity of the drying airflow. More preferably, the drying holes 105 on the first side plate 106 and the second side plate 107, which belong to two evaporation plates on both sides of a single drying zone, are also staggered, that is, the projections of the drying holes 105 on the first side plate 106 and the second side plate 107 in the longitudinal direction do not overlap.

[0040] More specifically, in a preferred embodiment of this application, the drying hole 105 is a waist-shaped hole extending laterally, thereby increasing the number of drying holes 105 arranged within a unit area while minimizing the accidental intrusion of mineral powder.

[0041] Of course, the arrangement of the drying holes 105 is not limited to the above-mentioned structural form. In another preferred embodiment of this application, the drying holes 105 are waist-shaped holes that extend vertically, so as to further increase the lateral blowing range of a single drying hole 105 on the agglomerates, thereby significantly improving the drying capacity of the drying holes 105 on the agglomerates.

[0043] Further, in the preferred embodiment of the present application, at least one support plate 109 is arranged between the first side plate 106 and the second side plate 107, both ends of the support plate 109 contact the first side plate 106 and the second side plate 107, and the support plate 109 is fixed on the first side plate 106 and / or the second side plate 107, preferably, the support plate 109 is fixed on the first side plate 106 and / or the second side plate 107 by welding.

[0044] Further, each support plate 109 is arranged in an array in the evaporation air duct, preferably, the projection of each support plate 109 in the transverse direction does not overlap the projection of each drying hole 105 in the transverse direction, which not only avoids the influence of the arrangement of the support plate 109 on the exhaust hot air of the drying hole 105, but also reduces the deformation of the side plate caused by welding.

[0045] Further preferably, in the preferred embodiment of the present application, a plurality of support plates 109 are arranged in an array in the evaporation air duct, preferably, two adjacent rows of support plates 109 are staggered to improve the uniformity of the support plate 109 supporting the adjacent two first side plates 106 and second side plates 107, and avoid the evaporation plate deformation caused by the lump acting on the support plate 109.

[0046] More specifically, in the preferred embodiment of the present application, the support plate 109 extends in the longitudinal direction, and the angle between the support plate 109 and the horizontal plane is between 30° and 60°, preferably, the angle between the support plate 109 and the horizontal plane is 30°, 40°, 45°, 50° or 60°.

[0047] Further, in the preferred embodiment of the present application, the support plates 109 on the first side plate 106 and the second side plate 107 are staggered and fixed by welding, for example, four rows and five columns of support plates 109 are arranged in the drying air duct, wherein the support plates 109 in the first, third and fifth columns of the first and third rows are welded on the first side plate 106, the support plates 109 in the second and fourth columns of the first and third rows are welded on the second side plate 107; the support plates 109 in the first, third and fifth columns of the second and fourth rows are welded on the second side plate 107, and the support plates 109 in the second and fourth columns of the second and fourth rows are welded on the first side plate 106, thereby significantly reducing the deformation amount of the evaporation plate.

Preferably, the detection module 110 is arranged in each drying section, so as to control the drying degree in each drying section.

[0049] Specifically, the detection module 110 comprises a mounting pipe penetrating through the side wall of the frame and a temperature sensor, the sensing end of the temperature sensor penetrates through the mounting pipe and extends into the drying section, for detecting the temperature in the drying section.

[0050] Further, as shown in the figures, Figure 1 , Figure 2 , Figure 3 , Figure 16 and 17 , in the preferred embodiment of the present application, the briquette drying device further comprises a base 2, and the base 2 comprises a support 201 and a first discharge chute.

[0051] The support 201 is fixedly installed on the bottom end surface of the frame 101, for supporting the drying member 1. Preferably, the support 201 is a support frame structure comprising four supporting legs. The first discharge chute comprises two first inclined guide plates 202 arranged in opposite positions, and the two first inclined guide plates 202 extend along the longitudinal direction and are fixed on the support 201, so as to form a first V-shaped chute structure, and meanwhile, the top inlet of the first V-shaped chute is directed towards the bottom opening of the frame 101, so that the first V-shaped chute can accurately receive the briquettes dried by the drying member 1. Correspondingly, the bottom of the first V-shaped chute is formed with an outlet extending along the longitudinal direction, so that the dried briquettes received by the first V-shaped chute can fall onto the transfer conveyor through the outlet extending along the longitudinal direction.

[0052] Further preferably, in the preferred embodiment of the present application, the projections of the drying channels 102 in the vertical direction all fall on the first discharge chute, which also ensures that all the briquettes dried by the drying member 1 can fall into the first V-shaped chute, thereby providing stable and accurate guidance for the collection of the briquettes.

[0053] More specifically, in the preferred embodiment of the present application, the top of the first inclined guide plate 202 is provided with a horizontal outward turning plate, and further, at least one supporting corbel 203 is arranged between the first inclined guide plate 202 and the support 201, and preferably, the supporting corbel 203 is a plurality of supporting corbels arranged in the longitudinal direction, so as to fixedly install the first inclined guide plate 202 on the support 201, thereby significantly improving the structural stability of the first inclined guide plate 202, and then improving the guidance stability for the collection of the briquettes.

[0054] Preferably, the support bracket 203 comprises an inclined support rod 505 and a V-shaped support rod abutting on the first inclined guide plate 202, the horizontal part of the V-shaped support rod is fixed on the support frame 201, and the horizontal part abuts on the bottom end surface of the everted plate; the inclined part of the V-shaped support rod abuts on the outer side wall surface of the first inclined guide plate 202. One end of the inclined support rod 505 is fixedly installed on the support frame 201, and the other end of the inclined support rod 505 is fixed in the region away from the horizontal part, so as to ensure that the support bracket 203 can form stable support to the first inclined plate.

[0055] Further, in the preferred embodiment of the present application, the base 2 further comprises a plurality of second discharge grooves arranged continuously in the transverse direction. Preferably, each second discharge groove is arranged between the first discharge groove and the frame body 101.

[0056] The second discharge groove comprises two second inclined guide plates 204 arranged oppositely, the two second inclined guide plates 204 extend in the longitudinal direction and are fixed on the support frame 201 to form a second V-shaped groove. Meanwhile, the projection of the drying channel 102 in the vertical direction falls within the plane formed by the top inlet of each second V-shaped groove. Further, the projection of the bottom outlet of each second V-shaped groove in the vertical direction falls within the range of the top inlet of the first V-shaped groove.
