Description

Technical Field

[0001] This utility model belongs to the field of metallurgical mineral processing technology, specifically relating to a modular agglomerate 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.

[0004] Meanwhile, the drying equipment in this technology needs to be set up on-site, resulting in a long construction period. Furthermore, if the number of drying units needs to be adjusted, the on-site setup and construction must be completely redesigned. Utility Model Content

[0016] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include: (1) The modular agglomerate drying device of this utility model includes multiple modular drying mechanisms and an air supply and exhaust mechanism. Each modular drying mechanism is arranged sequentially along the longitudinal direction, and a connecting structure is provided between adjacent modular drying mechanisms. The modular drying mechanism includes two drying components; the drying component includes a frame, a first evaporation plate, and a second evaporation plate. The first evaporation plate and the second evaporation plate are arranged alternately along the longitudinal direction in the drying channel. The first evaporation plate and the second evaporation plate are provided with drying holes. The air supply and exhaust mechanism is used to provide hot air to the first evaporation plate and the second evaporation plate or to extract hot air. The agglomerate drying device can achieve efficient drying of agglomerates, fully remove moisture from the agglomerates, thereby reducing powder adhering to the agglomerates. At the same time, it can be flexibly adjusted according to customer needs, significantly reducing the construction cycle.

[0017] (2) The modular agglomerate drying device of this utility model has a plurality of support plates arranged in an array between the first side plate and the second side plate, and the adjacent rows of support plates are staggered to improve the uniformity of support between the two adjacent first side plates and the second side plate, and avoid deformation of the evaporation plate when the agglomerates act on the support plates. Furthermore, by staggering the support plates on the first side plate and the second side plate, the deformation of the evaporation plate is further reduced.

[0018] (3) The modular agglomerate drying device of this utility model can accurately collect the temperature of the dried agglomerates by setting a detection module including a temperature sensor and a mounting tube in each drying zone, so that users can accurately obtain the degree of agglomerate drying based on the temperature information.

[0019] (4) The modular agglomerate drying device of this utility model uses an inverted V-shaped distribution plate set in the middle area of ​​the top inlet of the second discharge trough, which enables the inverted V-shaped distribution plate to stably guide and classify the agglomerates, thereby making the agglomerates on both sides more uniform. At the same time, the inverted V-shaped distribution 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.

[0020] (5) The modular agglomerate drying device of this utility model is efficient in drying, stable in operation, and convenient in use. Through the modular drying mechanism, users can select the number of modular drying mechanisms according to their needs, and the modular drying mechanism can be easily assembled through the connection structure between two adjacent modular drying mechanisms, thereby significantly reducing the construction efficiency of the drying furnace. At the same time, through the array of drying holes set on the evaporation plate, and combined with the position of the drying holes on the evaporation plate, the hot air in the evaporation plate can fully dry the agglomerates in the drying zone. Furthermore, combined with the first and second discharge troughs set vertically at intervals on the base, the first and second discharge troughs can achieve stable collection of agglomerates while minimizing the impact of agglomerates on the discharge troughs during the falling process. This not only improves the agglomerate collection efficiency, but also significantly extends the service life of the modular agglomerate drying device, and has good promotional value and application prospects.

[0028] Example: Please see Figures 1-20 The modular agglomerate drying device 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. At the same time, it can be flexibly adjusted according to customer needs, significantly reducing the construction cycle.

[0029] Specifically, such as Figures 1-20 As shown in the preferred embodiment of this application, the modular agglomerate drying device dries the agglomerates using hot air in the hot air duct 604. The modular agglomerate drying device includes multiple modular drying mechanisms 3 and an exhaust mechanism 6.

[0030] Each modular drying unit 3 is arranged sequentially along the longitudinal direction, and a connecting structure is provided between adjacent modular drying units 3 to fix them together as a whole. In actual use, users can select the number of modular drying units 3 according to their needs, and conveniently assemble the modular drying units 3 through the connecting structure between adjacent modular drying units 3, thereby significantly reducing the construction efficiency of the drying oven. Preferably, the connecting structure includes angle steel set at the edges of adjacent drying units 3 and connecting bolt assemblies for connecting the angle steel. Alternatively, the connecting structure includes a welded layer set between the edges of adjacent drying units 3.

[0031] The modular 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.

[0032] 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 evaporation duct 111 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 the waste heat flue gas 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.

[0033] 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.

[0034] Furthermore, the exhaust system 6 includes a first ventilation duct 601, a second ventilation duct 602, a reversing chamber 605, a hot air duct 604, and an exhaust duct 603.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] It is worth noting that in the preferred embodiment of this application, the vertical direction refers to a direction perpendicular to or perpendicular to the horizontal plane. The extension direction of each evaporator plate is transverse. The direction in which the evaporator plates are spaced apart is longitudinal, and in the horizontal plane, the longitudinal and transverse directions are perpendicular.

[0039] Furthermore, in a preferred embodiment of this application, a plurality of connecting structures are also provided between two adjacent drying components 1 to facilitate the convenient assembly of a single modular drying mechanism 3. Preferably, a connecting structure is provided on the side wall of the frame 101 of two adjacent drying components 1, the connecting structure including angle steel provided at the edges of the frames 101 of the two adjacent drying components 1 and connecting bolt assemblies connecting the angle steel. Alternatively, the connecting structure includes a welded layer provided between the edges of the frames 101 of the two adjacent drying components 1.

[0040] Preferably, a limiting structure is provided at the ends of the opposing frames 101 of two adjacent drying components 1. The limiting structure is preferably a U-shaped slot structure fixedly installed at the ends of the frames 101. In actual use, the end of one frame 101 is directly inserted into the U-shaped slot structure at the ends of the adjacent frames 101, thereby achieving initial limiting between the two adjacent frames 101. Then, the modular drying mechanism 3 is quickly assembled by combining the connecting structure provided on the outer wall of the two adjacent frames 101.

[0041] Furthermore, in a preferred embodiment of this application, the vertical projections of the evaporation plates in two adjacent drying components 1 do not overlap, so that after the clump passes through the drying space of the upper drying component 1, most of the clump will fall onto the evaporation plate of the lower drying component 1, causing the clump to flip over, thereby ensuring that the drying equipment fully dries each surface of the clump.

[0042] Furthermore, such as Figures 14-18 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.

[0043] 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.

[0044] 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.

[0045] More preferably, such as Figure 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] More specifically, in a preferred embodiment of this application, a plurality of connecting pipes 111 are provided between two adjacent evaporating plates, and both ends of adjacent connecting pipes 111 penetrate the plate body of the evaporating plate, thereby connecting the evaporation ducts in the two evaporating plates through the connecting pipes 111. Preferably, the cross-section of the connecting pipe 111 is square, circular, or irregular in shape. More preferably, a wear-resistant layer is provided on the top of the connecting pipe 111, and the top of the connecting pipe 111 is a wedge-shaped surface to ensure that clumps do not continuously wear down the connecting pipe 111, thereby improving the service life of the drying component 1.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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°.

[0054] 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.

[0055] More preferably, such as Figure 13 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.

[0056] 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.

[0057] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 19 and Figure 20 As shown in the preferred embodiment of this application, it also includes a base 2, which includes a bracket 201 and a first discharge trough.

[0058] 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.
