Description

Technical Field

[0001] This invention belongs to the field of metallurgical mineral processing technology, and specifically relates to a pellet drying device. Background Technology

[0002] Lump ore is a primary raw material used in metallurgical production. It is obtained from raw ore with a certain particle size after being mined, crushed, and screened. During the mining process, lumps often require water spraying for dust suppression. The dust generated during mining adheres to the ore surface after being soaked in water and is difficult to remove by screening. As a result, a large amount of powder is carried into the metallurgical reduction process, ultimately causing a deterioration in the permeability of the furnace charge.

[0003] In related technologies, although powerful screening devices are configured in the production process, the strong adhesion of water-containing dust makes it impossible to effectively separate the ore and its surface powder. Meanwhile, lumps are a primary raw material used directly and generally only remain in storage yards and raw material silos in metallurgical furnaces. Storage yards have large storage capacities, allowing for long-term storage. In the past, sunlight exposure was used to reduce surface moisture in the lumps, ultimately separating the ore from the adhering powder. However, this required dump trucks for turning the lumps, which was not only labor-intensive but also generated significant dust during the turning process. Furthermore, the storage layer could not be too thick, otherwise, the turning operation to reduce the surface moisture of the lumps could not be completed. Summary of the Invention

[0029] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include:

[0030] (1) The agglomerate drying equipment of the present invention includes a drying component, which includes a frame and a plurality of evaporation plates. The frame includes a drying channel extending in a vertical direction, and the top opening of the drying channel is a drying feed inlet. Each evaporation plate is fixed in the drying channel at intervals along the longitudinal direction to form a plurality of spaced drying zones in the drying channel; an evaporation duct is provided in the evaporation plate in a transverse direction, and the two ends of the evaporation duct penetrate the side wall of the frame for introducing hot air from the hot air pipeline; a plurality of drying holes are provided on the evaporation plate to connect the drying zones and the evaporation duct for blowing hot air from the hot air pipeline into the drying zones. This agglomerate drying equipment can achieve efficient drying of agglomerates, fully remove moisture from the agglomerates, thereby reducing powder adhering to the agglomerates, and thus significantly reducing the powder rate entering the furnace.

[0031] (2) The agglomerate drying device of the present invention comprises a plurality of support plates arranged in an array between the first side plate and the second side plate, and the support plates are arranged in an alternating manner between adjacent rows, so as to improve the uniformity of support between the two adjacent first side plates and the second side plate and avoid deformation of the evaporator plate when the agglomerates act on the support plates. Furthermore, by fixing the support plates on the first side plate and the second side plate in an alternating manner, the deformation of the evaporator plate is further reduced.

[0032] (3) The agglomerate drying equipment of the present invention uses a detection module, which includes a temperature sensor and a mounting pipe, in each drying zone to accurately collect the temperature of the dried agglomerates, thereby enabling users to accurately obtain the degree of agglomerate drying based on the temperature information.

[0033] (4) The agglomerate drying equipment of the present invention, by means of an inverted V-shaped dividing plate set in the middle area of ​​the top inlet of the second discharge trough, enables the inverted V-shaped dividing plate to achieve stable guiding and sorting of agglomerates, thereby making the agglomerates on both sides more uniform. At the same time, the inverted V-shaped dividing plate set in the middle area of ​​the second discharge trough can also reduce the impact caused by the falling agglomerates, avoiding deformation of the second discharge trough caused by the impact load of the agglomerates. Furthermore, combined with the baffle plate set at the bottom discharge port of the second discharge trough, the falling speed of the agglomerates is further reduced, avoiding deformation of the first discharge trough caused by the impact load of the agglomerates.

[0034] (5) The agglomerate drying equipment of the present invention is efficient, stable in operation, and convenient to use. It utilizes a vertically extending drying channel and several evaporation plates arranged longitudinally at intervals within the drying channel. This allows the agglomerates to be fully dried as they fall from the top of the drying channel to the first and second discharge troughs at the bottom. Simultaneously, the array of drying holes on the evaporation plates, combined with their positions, ensures that the hot air within the evaporation plates can fully dry the agglomerates within the drying zone. Furthermore, the first and second discharge troughs, arranged vertically at intervals on the base, ensure stable collection of agglomerates while minimizing the impact of the agglomerates falling on the discharge troughs. This not only improves the agglomerate collection efficiency but also significantly extends the service life of the agglomerate drying equipment, demonstrating good promotional value and application prospects.

[0062] Example:

[0063] Please see Figures 1-17 The agglomerate drying equipment in the preferred embodiment of the present invention can achieve efficient drying of agglomerates, fully remove moisture from the agglomerates, thereby reducing powder adhering to the agglomerates and thus significantly reducing the powder rate entering the furnace.

[0064] Specifically, such as Figures 1-17 As shown in the preferred embodiment of this application, the agglomerate drying equipment dries the agglomerates using hot air in the hot air duct 604. The agglomerate drying equipment includes a drying mechanism 3 and an air supply and exhaust mechanism 6.

[0065] The drying mechanism 3 includes at least two drying components 1 arranged sequentially along a vertical direction. Each drying component 1 includes a frame 101 extending vertically, a first evaporator plate 103, and a second evaporator plate 112. The frame 101 includes a drying channel 102 extending vertically, with its top opening serving as a drying inlet to allow lumps to enter the drying channel 102 for drying. Simultaneously, the first evaporator plate 103 and the second evaporator plate 112 are arranged longitudinally in a staggered pattern within the drying channel 102, forming several spaced drying spaces within the drying channel 102.

[0066] The first evaporator plate 103 has a through first evaporation duct 104 arranged horizontally inside, and the second evaporator plate 112 has a through second evaporator plate 112 arranged horizontally inside. At least one drying hole 105 is provided on both side walls of the first evaporator plate 103 and the second evaporator plate 112 so that hot air in the first evaporation duct 104 and the second evaporation duct 111 can flow into the drying space through the drying hole 105, thereby achieving effective drying of the lumps in the drying space.

[0067] Meanwhile, a first opening 113 is provided on the first side wall of the frame 101 to connect to the first evaporation duct 104, and correspondingly, a second opening 114 is provided on the second side wall of the frame 101 to connect to the second evaporation duct 111, so that the exhaust mechanism 6 can supply and exhaust air to the adjacent first evaporation plates 103 and second evaporation plates 112 from the first opening 113 and the second opening 114.

[0068] Furthermore, the ventilation system 6 includes a first ventilation duct 601, a second ventilation duct 602, a reversing chamber 605, and an exhaust duct 603.

[0069] The reversing chamber 605 is connected to the first ventilation duct 601, the second ventilation duct 602, the exhaust duct 603, and the hot air duct 604. Simultaneously, a reversing element 606 is installed within the reversing duct to divide the reversing chamber 605 into two spaces. Before and after switching using the reversing element 606, the first ventilation duct 601 can be switched from being connected to the exhaust duct 603 to being connected to the hot air duct 604, while the second ventilation duct 602 can be switched from being connected to the hot air duct 604 to being connected to the exhaust duct 603. Alternatively, the first ventilation duct 601 can be switched from being connected to the hot air duct 604 to being connected to the exhaust duct 603, while the second ventilation duct 602 can be switched from being connected to the exhaust duct 603 to being connected to the hot air duct 604.

[0070] Meanwhile, the first ventilation pipe 601 is connected to each of the first openings 113, and the second ventilation pipe 602 is connected to each of the second openings 114. In actual use, through the hot air pipe 604 and the exhaust pipe 603 connected by the first ventilation pipe 601 and the second ventilation pipe 602, the adjacent first evaporator plate 103 and the second evaporator plate 112 are respectively in the air supply state and the air exhaust state, thereby forming a longitudinally flowing drying airflow on both sides of the drying space, preventing the dried flue gas from extending longitudinally and being discharged from the drying feed inlet, thereby reducing the discharge of dusty drying flue gas to the outside of the drying equipment and preventing the spread of flue gas dust pollution.

[0071] Furthermore, by switching the pipelines connected to the first ventilation pipe 601 and the second ventilation pipe 602 through the reversing component 606, the first evaporator plate 103 and the second evaporator plate 112 are switched to the exhaust state and the air supply state respectively, so as to achieve full drying of the lump ore through the drying form of longitudinal air circulation drying on both sides.

[0072] It is worth noting that in the preferred embodiment of this application, the vertical direction is perpendicular to or perpendicular to the horizontal plane. The extension direction of each evaporator plate is transverse. The evaporator plates are spaced apart in the longitudinal direction, and in the horizontal plane, the longitudinal and transverse directions are perpendicular.

[0073] Furthermore, such as Figures 10-15 As 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] Furthermore, in another preferred embodiment of this application, the drying hole 105 includes both a waist-shaped hole extending laterally and a waist-shaped hole extending vertically.

[0080] Furthermore, in a preferred embodiment of this application, at least one support plate 109 is provided between the first side plate 106 and the second side plate 107. Both ends of the support plate 109 are in contact with 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.

[0081] Furthermore, the support plates 109 are arranged in an array in the evaporation duct. Preferably, the projection of each support plate 109 in the lateral direction does not coincide with the projection of each drying hole 105 in the lateral direction. This not only avoids the influence of the support plate 109 on the hot air discharged from the drying hole 105, but also reduces the deformation of the side plate caused during the welding process.

[0082] Further preferably, in the preferred embodiment of this application, a plurality of support plates 109 are arranged in an array in the evaporation duct. Preferably, two adjacent rows of support plates 109 are staggered to improve the uniformity of support between the support plates 109 and the two adjacent first side plates 106 and second side plates 107, and to avoid deformation of the evaporation plate caused by the action of clumps on the support plates 109.

[0083] More specifically, in the preferred embodiment of this application, the support plate 109 extends longitudinally, 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°.

[0084] Furthermore, in a preferred embodiment of this application, the support plates 109 on the first side plate 106 and the second side plate 107 are staggered and welded together. For example, a four-row, five-column arrangement of support plates 109 is provided in the drying air duct. The support plates 109 in the first, third, and fifth columns of the first and third rows are welded to the first side plate 106, and the support plates 109 in the second and fourth columns of the first and third rows are welded to the second side plate 107. The support plates 109 in the first, third, and fifth columns of the second and fourth rows are welded to the second side plate 107, and the support plates 109 in the second and fourth columns of the second and fourth rows are welded to the first side plate 106, thereby significantly reducing the deformation of the evaporation plate.

[0085] More preferably, such as Figure 10 As shown in the preferred embodiment of this application, the drying component 1 further includes a detection module 110 disposed in at least one drying zone, and the detection module 110 is disposed at the outlet of the drying zone to detect the temperature of the lumps and thereby calculate the degree of drying of the lumps. Preferably, a detection module 110 is disposed in each drying zone to achieve control over the degree of drying in each drying zone.

[0086] Specifically, the detection module 110 includes an installation tube that penetrates the side wall of the frame and a temperature sensor. The sensing end of the temperature sensor passes through the installation tube and extends into the drying zone to detect the temperature within the drying zone.

[0087] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 16and 17 As shown in the preferred embodiment of this application, the agglomerate drying equipment further includes a base 2, which includes a support 201 and a first discharge trough.

[0088] The bracket 201 is fixedly installed on the bottom surface of the frame 101 to support the drying component 1. Preferably, the bracket 201 is a support frame structure including four legs. The first discharge trough includes two first inclined guide plates 202 arranged at relatively intervals. The two first inclined guide plates 202 extend longitudinally and are fixed on the bracket 201 to form a first V-shaped groove structure. At the same time, the top inlet of the first V-shaped groove opens towards the bottom of the frame 101 so that the first V-shaped groove can accurately receive the lumps dried by the drying component 1. Correspondingly, a longitudinally extending discharge port is formed at the bottom of the first V-shaped groove so that the dried lumps received by the first V-shaped groove can fall onto the transfer conveyor belt through the longitudinally extending discharge port.

[0089] More preferably, in the preferred embodiment of this application, the vertical projection of the drying channel 102 falls on the first discharge trough, which also ensures that all lumps dried by the drying component 1 can fall into the first V-shaped groove, thereby providing a stable and accurate guide for the collection of lumps.

[0090] More specifically, in a preferred embodiment of this application, a horizontal outward flap is provided on the top of the first inclined guide plate 202. Furthermore, at least one supporting bracket 203 is provided between the first inclined guide plate 202 and the bracket 201. Preferably, there are multiple supporting brackets 203 spaced apart along the longitudinal direction, so as to fix the first inclined guide plate 202 on the bracket 201, thereby significantly improving the structural stability of the first inclined guide plate 202 and thus improving the guiding stability of the agglomerate collection.

[0091] Preferably, the supporting bracket 203 includes an inclined support rod 505 and a V-shaped support rod attached to the first inclined guide plate 202. The horizontal portion of the V-shaped support rod is fixed to the bracket 201 and abuts against the bottom surface of the outer flap; the inclined portion of the V-shaped support rod abuts against the outer wall surface of the first inclined guide plate 202. One end of the inclined support rod 505 is fixedly installed on the bracket 201, while the other end of the inclined support rod 505 is fixed in the area where the inclined portion faces away from the horizontal portion, to ensure that the supporting bracket 203 can provide stable support for the first inclined plate.

[0092] Furthermore, in a preferred embodiment of this application, the base 2 further includes a plurality of second discharge troughs arranged continuously in a transverse direction. Preferably, each of the second discharge troughs is disposed between the first discharge trough and the frame 101.

[0093] The second discharge trough includes two relatively spaced second inclined guide plates 204, which extend longitudinally and are fixed to the bracket 201 to form a second V-shaped groove. Simultaneously, the vertical projection of the drying channel 102 falls within the plane formed by the top inlets of each of the second V-shaped grooves. Furthermore, the vertical projection of the bottom discharge outlets of each second V-shaped groove falls within the area of ​​the top inlet of the first V-shaped groove.

[0094] In actual use, the lumps dried in the drying zone fall into the various second discharge troughs, which not only collect the dried lumps but also provide initial cushioning during their descent.
