Description

Technical Field

[0001] The utility model relates to the technical field of soot treatment, in particular to a movable dust removal hood structure for a train screw unloading workshop. Background Art

[0002] Train unloading has the advantages of short operation time and large one-time unloading volume. Therefore, there is a train unloading process flow in the raw material areas of many steel mills. Screw unloading is one of the forms of train unloading, but a large amount of soot will be generated during this unloading form. The form of ultra-low emission transformation in steel mills is becoming more and more urgent, and the treatment of unorganized soot in steel mills is imminent.

[0003] Since during train screw unloading, the screw unloader needs to move back and forth in the carriage to ensure that all materials are unloaded into the silo, the dust generation points are not fixed, and the unloading workshop is not an enclosed factory building, so the design of dust removal and dust suppression is extremely difficult.

[0004] Prior art one: The soot is treated by the form of dry fog dust suppression. The specific treatment measure is to set a dry fog dust suppression device at the underground silo in the train unloading workshop, and spray dry fog to combine with the dust during train unloading to play a role in soot suppression. Using dry fog dust suppression to treat soot will cause a significant increase in the moisture content of the material, resulting in a significant increase in energy consumption during blast furnace smelting, increasing the blast furnace smelting cost, and it is difficult to solve this dust suppression means for hydrophobic materials such as dry quenched coke.

[0005] Prior art two: The soot is treated by the form of overall workshop enclosure. The specific treatment measure is to enclose the train unloading workshop as an enclosed factory building, and collect the soot through a dust removal pipeline on the side wall of the factory building. Enclosing the factory building as an enclosed factory building can reduce the escape of soot during unloading to a certain extent, but the required dust removal air volume is very large and the effect is not significant. At the same time, soot will also escape from the poorly sealed places.

[0006] Therefore, based on the experience and practice of being engaged in the relevant industry for many years, the inventor proposes a movable dust removal hood structure for a train screw unloading workshop to overcome the defects of the prior art. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a movable dust removal hood structure for a train screw unloading workshop.

[0044] As Figure 1 、 Figure 2 、 Figure 3 shown, the present utility model provides a mobile dust removal hood structure for a train screw unloading workshop, including:

[0045] The hood body 11 can horizontally move synchronously with the spiral car dumper 9 and can cover the underground bunker 12. A smoke storage bin 8 is arranged at the top of the hood body 11, and a dumper passage opening is arranged at the top end of the smoke storage bin 8. The dumper passage opening is arranged to be openable or closable; a through train passage is arranged below the dumper passage opening, and the train 10 passes through the train passage, that is, a through notch is arranged on the side plate along the moving direction of the hood body 11, and the size of the through notch is slightly larger than the cross-sectional size of the train carriage (not too large to avoid excessive escape of smoke and dust); the bottom of the hood body 11 is communicated with the underground bunker 12; except for the train passage (at the horizontal middle position of the hood body 11) and the bottom, the hood body 11 is sealed, and a sealed space is formed at the unloading place under the condition of ensuring the unloading process, and the escape of smoke and dust during the unloading process from the hood body 11 is minimized as much as possible.

[0046] The dust removal connecting pipe 7, the first end of the dust removal connecting pipe 7 is communicated with the smoke storage bin 8, and the second end of the dust removal connecting pipe 7 is movably communicated with the dust removal structure in the unloading workshop.

[0047] By adopting the utility model, on the one hand, the tightness of the unloading area and the smoke and dust capture rate during unloading can be enhanced, the realization of ultra-low emission can be promoted, and the consequences such as production reduction and production stoppage caused by the escape of smoke and dust can be avoided; on the other hand, by adopting the utility model, the dust removal air volume can be greatly reduced, and the investment cost of environmental protection transformation can be reduced; finally, the utility model combines the moving dust removal hood with the dust removal structure in the unloading workshop, can meet the characteristic that the operation points of the spiral car dumper are not fixed, and ensures that the process operation is not affected by the transformation.

[0048] The hood body 11 of the utility model can be perfectly fitted with the spiral car dumper at the train unloading place, and can minimize the required dust removal air volume to the greatest extent and meet the characteristic that the operation points of the spiral car dumper are not fixed under the premise of ensuring the dust removal effect, without any impact on the process facilities.

[0049] Further, as Figure 1 、 Figure 2 shown, the utility model further includes a dust removal hood track 1 arranged on both sides of the underground bunker 12 in the unloading workshop (extending along the traveling direction of the train 10) and used for guiding the movement of the hood body 11.

[0050] Further, as Figure 1 、 Figure 3 shown, the hood body 11 is supported on a plurality of columns 4 (steel columns can be used), pulleys 2 are arranged at the bottom ends of the columns 4, a reduction motor 3 is connected to the pulleys, and the reduction motor 3 drives the hood body 11 to move along the dust removal hood track 1 through the pulleys 2. The reduction motor 3 is used to control the start, movement and stop of the hood body 11.

[0051] Further, the reduction motor 3 is interlocked with the screw car dumper 9 so that the hood body 11 moves horizontally synchronously with the screw car dumper 9.

[0052] Further, as Figure 2 shown, two split telescopic roof panels 13 are arranged at the car dumper passage opening. The telescopic roof panel 13 can be an electric telescopic roof panel and is interlocked with the screw car dumper 9.

[0053] Further, the car dumper passage opening is arranged in an oval shape (the dimension of the car dumper passage opening along the track direction is smaller than the dimension perpendicular to the track direction), so as to accommodate the possible lateral deviation of the screw car dumper 9.

[0054] Further, as Figure 1 、 Figure 2 shown, the dust removal structure of the unloading workshop is arranged on one side of the smoke storage bin 8. A movable joint 6 is arranged at the second end of the dust removal connecting pipe 7, and the movable joint 6 can be hermetically connected with the dust removal structure of the unloading workshop.

[0055] Further, the movable joint 6 includes a joint pipe, and connecting flanges are arranged at both ends of the joint pipe.

[0056] The dust removal structure of the unloading workshop can be a ventilation trough structure 5 arranged on the top of the workshop. The ventilation trough structure includes a ventilation trough body with an open top end. A pressing belt structure is hermetically and movably arranged above the open top end of the ventilation trough body. A communication port structure is arranged on the pressing belt structure. The dust removal connecting pipe 7 is connected to the communication port structure through the movable joint 6; the communication port structure can move along with the movement of the dust removal hood.

[0057] The dust removal structure of the unloading workshop can also be a butt - type dust removal pipeline. External process pipelines are arranged at positions of the butt - type dust removal pipeline corresponding to each underground feeding bin 12. The dust removal connecting pipe 7 arranged at the smoke storage bin 8 is attached to the external process pipeline. When the dust removal hood moves to the position of the underground feeding bin 12, the dust removal connecting pipe 7 is docked with the external pipeline through the movable joint 6 to capture the smoke and dust.

[0059] Further, the cross - section of the top of the hood body 11 is tapered from bottom to top, that is, the top is in a converging setting, which is beneficial to the concentration of the smoke and dust.

[0060] The usage method of the movable dust removal hood structure for the train screw unloading workshop of the present utility model is as follows:

[0061] When the train 10 travels into the workshop, the screw unloader 9 starts. Through process interlock settings, the hood body 11 can move simultaneously and synchronously with the screw unloader 9. It stops when it moves above the underground bunker 12. At this time, the telescopic roof panel 13 at the top of the smoke storage bin 8 opens to both sides, exposing the unloader passage opening. The unloading brush (prior art) of the screw unloader 9 descends into the hood body 11 to unload the train carriage. At this time, the telescopic roof panel 13 closes inward. The hood body 11 moves back and forth with the screw unloader 9. The dust removal connecting pipe 7 is connected to the ventilation trough structure 5 through a movable joint 6 and can move with the movement of the hood body 11. After unloading one carriage, the screw unloader 9 lifts, and the hood body 11 moves with the screw unloader 9 to the next carriage to continue unloading. The ventilation trough structure 5 can be connected to an external dust removal pipeline to capture and purify the smoke and dust.

[0062] As described above, the mobile dust removal hood structure for a train screw unloading workshop of the present utility model has the following beneficial effects:

[0063] By adopting the present utility model, on the one hand, it can enhance the tightness of the unloading area and the smoke and dust capture rate during unloading, promote the realization of ultra-low emissions, and avoid consequences such as production reduction and production stoppage caused by smoke and dust escape; on the other hand, adopting the present utility model can greatly reduce the dust removal air volume and the investment cost of environmental protection transformation; finally, the present utility model combines the moving dust removal hood with the dust removal structure of the unloading workshop, which can meet the characteristics of the non-fixed operation point of the screw unloader and ensure that the process operation is not affected by the transformation.

[0064] The hood body of the present utility model can perfectly fit with the screw unloader at the train unloading place, and can minimize the required dust removal air volume to the greatest extent while ensuring the dust removal effect, meet the characteristics of the non-fixed operation point of the screw unloader, and have no impact on the process facilities.
