Description

Technical Field

[0001] This utility model belongs to the field of flue gas collection technology, specifically relating to a ladle flue gas collection device. Background Technology

[0002] In the pyrometallurgical process of non-ferrous metals, steel ladles are typically used to carry molten metal when it needs to be transferred. After the molten metal is poured from the furnace into the ladle, it is then transported to the next process step by a crane. However, before the ladle can be moved, the next process step may not be ready, and the ladle will have to wait. During this waiting period, the molten metal in the ladle will release a large amount of toxic and harmful gases and fumes. Direct discharge into the workshop will pollute the environment and endanger the health of workers.

[0003] In related technologies, steel ladles are typically transported to electric flatcars via overhead cranes. The electric flatcars then horizontally transport the ladles under a fume hood, where the hood collects the escaping fumes while the ladle waits. Once the next process is complete, the electric flatcars are first horizontally transported away from under the fume hood. After clearing sufficient lifting space for the overhead crane, the ladles are then lifted from the electric flatcars to the next process step. However, this method is complex, costly, and requires significant ground space for laying the transport tracks for the electric flatcars. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a ladle flue gas collection device that can collect the gas overflowing from the ladle without affecting the overhead crane's handling of the ladle, thus saving space and reducing costs.

[0005] The ladle flue gas collection device of this utility model includes: a driving assembly having an output end rotatable about a vertical axis; and a smoke collector having a smoke outlet connected to a smoke exhaust pipe, the smoke collector having a working position and a clearance position, the smoke collector being disposed at the output end of the driving assembly to be driven to the working position or the clearance position by the driving assembly; in the working position, the smoke collector is located above the ladle to collect the gas overflowing from the ladle; in the clearance position, the smoke collector is moved away from above the ladle.

[0006] In this embodiment, the ladle flue gas collection device, by setting up a drive assembly and a smoke collector, allows for the collection of flue gas escaping from the ladle. When collection is needed, the drive assembly moves the smoke collector to a clearance position, allowing the overhead crane to lift the ladle below the smoke collector in its working position. Since the smoke collector is in the clearance position, it does not interfere with the crane's lifting of the ladle. After the crane lifts the ladle into place, it separates from and moves away from the ladle. Then, the drive assembly moves the smoke collector to its working position, enabling the collection of flue gas from the ladle. When it is necessary to transfer the high-temperature solution inside the ladle to the next process, the smoke collector is moved to a clearance position by the drive component. The smoke collector will not interfere with the overhead crane's lifting of the ladle. The overhead crane is then brought close to and connected to the ladle, allowing it to lift the ladle to the next process. The entire waiting process before the ladle is transferred to the next process does not require the use of an electric flatcar for ladle transfer, nor does it require the use of tracks and tunnels for the electric flatcar. This saves costs and space, avoids the safety hazards caused by the electric flatcar for ladle transfer, and improves safety.

The smoke exhaust end of the smoke collector is connected to the flange and is rotatably connected to the smoke inlet of the smoke exhaust pipe on the same axis as the column. The smoke exhaust outlet of the smoke collector is connected to the smoke inlet of the smoke exhaust pipe.

[0013] In this embodiment, the flange includes a bushing and a mounting plate. The bushing has a connecting hole, the mounting plate is connected to the bushing, and the bushing is connected to the top of the column through the connecting hole.

[0014] In this embodiment, the driving assembly further includes: a first positioning component, which includes a first inductive switch and a first sensor.

[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] In this embodiment, as Figure 1 As shown, the ladle flue gas collection device includes a drive assembly 1 and a smoke collector 2. The drive assembly 1 has an output end that can rotate around a vertical axis. The exhaust port of the smoke collector 2 is connected to the exhaust pipe 300. The smoke collector 2 has a working position and a clearance position. The smoke collector 2 is located at the output end of the drive assembly 1 so that the drive assembly 1 can drive the smoke collector 2 to the working position or the clearance position. In the working position, the smoke collector 2 is located above the ladle 100 to collect the gas overflowing from the ladle 100. In the clearance position, the smoke collector 2 is moved away from above the ladle 100.

[0030] In this embodiment, the ladle flue gas collection device, by setting up a drive assembly 1 and a smoke collector 2, allows for the collection of flue gas escaping from the ladle 100. When it is necessary to collect the flue gas, the drive assembly 1 drives the smoke collector 2 to a clearance position. The overhead crane 200 can then lift the ladle 100 to a position below the smoke collector 2 when it is in its working position. Since the smoke collector 2 is in the clearance position, it will not interfere with the overhead crane 200's lifting of the ladle 100. After the overhead crane 200 lifts the ladle 100 into place, it separates from the ladle 100 and moves away from it. Then, the drive assembly 1 drives the smoke collector 2 to move it to its working position, thus allowing the flue gas inside the ladle 100 to be collected. The system collects the molten steel in the ladle 100. When it is necessary to transport the high-temperature solution in the ladle 100 to the next process, the smoke collector 2 is moved to a clearance position by the drive component 1. The smoke collector 2 will not interfere with the hoisting of the ladle 100 by the overhead crane 200. The overhead crane 200 is brought close to the ladle 100 and connected to it, so that the overhead crane 200 can hoist the ladle 100 to the next process. The entire waiting process before the ladle 100 is transported to the next process does not require the use of an electric flatcar to transfer the ladle 100, nor does it require the use of tracks and tunnels for the operation of the electric flatcar. This saves costs and space, avoids the safety hazards caused by the electric flatcar to transfer the ladle 100, and improves safety.

[0031] In this embodiment, as Figure 2 As shown, the drive assembly 1 includes a mounting base 11 and a rotary drive component 12. The rotary drive component 12 is disposed on the mounting base 11, and the smoke collection component 2 is disposed at the output end of the rotary drive component 12.

[0032] For example, the bottom of the mounting base 11 can be fixed to the ground, and the mounting base 11 can be a columnar structure, which can save space while providing support for the rotary drive component 12.

[0033] It is understandable that by setting the mounting base 11, the rotary drive component 12 can be supported while also being positioned above the ground. This allows the smoke collector 2 to be positioned above the ground via the rotary drive component 12, facilitating the placement of the ladle 100 below the smoke collector 2. The rotary drive component 12 can drive the smoke collector 2 to rotate, thereby moving it to a clearance position or a working position.

[0034] In this embodiment, as Figure 2 and Figure 3 As shown, the rotary drive component 12 includes a column 121 and a drive member 122. The column 121 is rotatably connected to the mounting base 11, and the smoke collection component 2 is connected to the column 121. The drive member 122 is disposed on the mounting base 11, and the column 121 is connected to the output end of the drive member 122 so as to drive the column 121 to rotate through the drive member 122.

[0035] For example, the drive component 122 can be a geared motor, and the column 121 is connected to the output shaft of the geared motor via a coupling, so that the column 121 can be driven to rotate by the geared motor. Directly driving the column 121 to rotate by the geared motor has high transmission efficiency and is conducive to the overall stable operation.

[0036] It is understandable that by rotatably connecting the column 121 to the mounting base 11 and connecting the smoke collection component 2 to the column 121, while driving the column 121 to rotate via the drive component 122, the smoke collection component 2 on it can also be driven to rotate around the rotation axis of the column 121.

[0037] In this embodiment, the ladle flue gas collection device also includes a controller 3, and the drive unit 122 is electrically connected to the controller 3 so as to control the start and stop of the drive unit 122 through the controller 3.

[0038] In this embodiment, the rotary drive component 12 further includes a support member 123, and the smoke collector 2 is connected to the column 121 through the support member 123.

[0039] For example, the support member 123 can be triangular in structure. By setting the support member 123 to a triangular structure, a stable support can be formed for the smoke collector 2. Alternatively, the support member 123 can be welded to the smoke collector 2, or the smoke collector 2 can be connected to the support member 123 by a detachable connection method such as bolts. The specific connection method between the smoke collector 2 and the support member 123 can be selected by those skilled in the art according to actual needs, and is not limited here.

[0040] It should be noted that by connecting the smoke collector 2 to the column 121 via the support 123, the distance between the smoke collector 2 and the column 121 can be easily controlled as needed, so as to facilitate the placement and removal of the ladle 100 and the correspondence between the positions of the smoke collector 2 and the ladle 100.

[0041] In this embodiment, as Figure 2 and Figure 3 As shown, the column 121 is vertically arranged on one side of the mounting base 11. The rotary drive component 12 also includes a first connector 124, which includes a bearing housing and a first bearing. The bearing housing is disposed in the mounting base 11, the first bearing is disposed in the bearing housing, and the column 121 passes through the first bearing.

[0042] Specifically, multiple first connectors 124 can be provided. For example, two, three, or four first connectors 124 can be provided. The specific number of first connectors 124 can be set according to actual needs and is not limited here. When multiple first connectors 124 are provided, the multiple first connectors 124 are arranged sequentially at intervals along the axial direction of the column 121. By providing multiple first connectors 124 to connect the column 121 to the mounting base 11, the reliability of the connection of the column 121 can be improved.

[0043] The bearing housing can be bolted to the mounting base 11. The specific fixing method of the bearing housing is conventional existing technology and will not be described in detail here.

[0044] In this embodiment, by setting a first connecting member 124, the column 121 can be rotated relative to its axis. The first connecting member 124 includes a bearing seat and a first bearing. Rotating the column 121 relative to its axis through the bearing can reduce the friction force when the column 121 rotates, which is beneficial to improving transmission efficiency and stability during rotation.

[0045] In this embodiment, as Figure 2 and Figure 3 As shown, the rotary drive component 12 also includes a flange 125, which is disposed on the top of the column 121. The smoke inlet of the smoke exhaust pipe 300 is located above the column 121. The smoke exhaust end of the smoke collector 2 is connected to the flange 125 and is coaxially rotatably connected to the smoke inlet of the smoke exhaust pipe 300 with the column 121. The smoke exhaust port of the smoke collector 2 is connected to the smoke inlet of the smoke exhaust pipe 300.

[0046] Specifically, the exhaust end of the smoke collector 2 can be connected to the exhaust pipe 300 via a rotary joint to reduce the friction when the smoke collector 2 rotates. The rotary joint is a conventional existing product, and its specific structure will not be described in detail here.

[0047] It should be noted that by installing a flange 125 on the top of the column 121 and connecting the exhaust end of the smoke collector 2 to the flange 125, the smoke collector 2 can be connected to the column 121 via the support 123 and the flange 125, which improves the stability of the smoke collector 2 installation. Furthermore, the exhaust end of the smoke collector 2 is coaxially rotatably connected to the inlet of the exhaust pipe 300 with the column 121, allowing the exhaust port of the smoke collector 2 to rotate relative to the exhaust pipe 300. Since the exhaust port of the smoke collector 2 is connected to the inlet of the exhaust pipe 300, the connection between the smoke collector 2 and the exhaust pipe 300 does not interfere with the rotation of the smoke collector 2 while the smoke collector 2 exhausts smoke into the exhaust pipe 300.

[0048] In this embodiment, as Figures 3 to 5As shown, flange 125 includes bushing 1251 and mounting plate 1252. Bushing 1251 has a connection hole. Mounting plate 1252 is connected to bushing 1251. Bushing 1251 is connected to the top of column 121 through connection hole.

[0049] For example, bushing 1251 and mounting plate 1252 are welded to improve the connection strength between bushing 1251 and mounting plate 1252. The diameter of the connecting hole of bushing 1251 can match the outer diameter of column 121 so that bushing 1251 is fitted onto the outside of column 121.

[0050] Multiple flanges 125 can be provided. The connecting holes of the bushings 1251 of the multiple flanges 125 have the same diameter to match the column 121. The mounting plates 1252 of the multiple flanges 125 have different specifications to adapt to different specifications of smoke collection components 2.

[0051] In this embodiment, the flange 125 includes a bushing 1251 and a mounting plate 1252. By providing the bushing 1251, the connection between the flange 125 and the column 121 can be facilitated. By providing the mounting plate 1252, the connection between the smoke collection component 2 and the mounting plate 1252 can be facilitated.

[0052] In this embodiment, as Figure 2 As shown, the smoke collection component 2 includes a smoke inlet hood 21 and a smoke exhaust pipe 300 segment connected in sequence. The smoke exhaust pipe 300 segment is connected to the inlet of the smoke exhaust pipe 300 and can move relative to the inlet of the smoke exhaust pipe 300.

[0053] Specifically, the fume hood 21 has a flared fume inlet to facilitate the entry of flue gas into the fume hood 21. The exhaust pipe section 22 includes a bent pipe section 221 and a straight pipe section 222 connected in sequence. The end of the bent pipe section 221 facing away from the straight pipe section 222 is connected to the exhaust port of the fume hood 21. The bent pipe section 221 is connected to the side wall of the straight pipe section 222. The straight pipe section 222 is vertically arranged, and its two axial ends are connected to the flange 125 and the exhaust pipe 300, respectively.

[0054] In this embodiment, as Figure 2 and Figure 3 As shown, the drive assembly 1 also includes a first positioning element 126 and a second positioning element 127. The first positioning element 126 includes a first inductive switch and a first sensor. The first inductive switch is disposed on the mounting base 11, and the first sensor is disposed on the column 121. When the smoke collector 2 rotates to the working position, the first sensor triggers the first inductive switch, and the first inductive switch sends a signal indicating that the smoke collector 2 is in position. The second positioning element 127 includes a second inductive switch and a second sensor. The second inductive switch is disposed on the mounting base 11, and the second sensor is disposed on the column 121. When the smoke collector 2 rotates to the clearance position, the second sensor triggers the second inductive switch, and the second inductive switch sends a signal indicating that the smoke collector 2 is in position.

[0055] Specifically, both the first and second inductive switches are electrically connected to the controller 3, so that the controller 3 controls the start and stop of the drive unit 122 according to the signals fed back by the first and second inductive switches, which helps to improve the rotation accuracy of the column 121.

[0056] Understandably, during the rotation of the column 121, the column 121 drives the first and second sensors to rotate. When the first sensor approaches the first sensor switch, the first sensor switch is triggered and sends a position signal. Based on the position signal sent by the first sensor, the drive unit 122 can be controlled to stop so that the smoke collector 2 can be accurately stopped in the working position. When the second sensor approaches the second sensor switch, the second sensor switch is triggered and sends a position signal. Based on the position signal sent by the second sensor, the drive unit 122 can be controlled to stop so that the smoke collector 2 can be accurately stopped in the avoidance position.

[0057] The ladle flue gas collection device in this embodiment also includes a position sensor (not shown in the figure). The position sensor can be installed on the mounting base 11. When the trolley 200 approaches the mounting base 11, the position sensor sends a signal to the controller 3. The controller 3 controls the drive assembly 1 to drive the flue gas collecting component 2 to the avoidance position. When the trolley 200 moves away from the mounting base 11, the position sensor sends a signal to the controller 3. The controller 3 controls the drive assembly 1 to drive the flue gas collecting component 2 to the working position, thereby realizing the interlock between the trolley 200 and the ladle flue gas collection device.

[0058] Example 2

[0059] The working principle of the ladle flue gas collection device in this embodiment is basically the same as that in Embodiment 1, with the specific differences being, for example... Figure 6 and Figure 7 As shown, the column 121 is disposed on the top of the mounting base 11. The rotary drive component 12 also includes a rotary reducer 128, which is disposed on the top of the mounting base 11. The bottom of the column 121 is connected to the rotary reducer 128, and the rotary reducer 128 is connected to the drive component 122.

[0060] Specifically, the inner ring of the rotary reducer 128 is connected to the top of the mounting base 11, the bottom of the column 121 is connected to the outer ring of the rotary reducer 128, the inner ring and the outer ring of the rotary reducer 128 are connected by a second bearing, the drive component 122 is connected to the worm gear of the rotary reducer 128, and the outer ring of the rotary reducer 128 is driven to rotate by the worm gear of the rotary reducer 128, thereby enabling the column 121 to rotate.

[0061] In this embodiment, the first inductive switch and the second inductive switch can be fixed to the rotary reducer 128 so that the first inductive switch can sense the first trigger, or the second inductive switch can sense the second trigger.

[0062] In this embodiment, by setting the column 121 on the top of the mounting base 11, the structure is simpler and more compact, which is more conducive to saving space, reducing costs, and making maintenance easier.
