Description
Technical field
The present invention relates to metallurgical technology field, particularly relate to a kind of sintering machine dust-fall pipe arrangement.
Background technology
Sintering machine is the most important equipment that iron and steel metallurgy enterprise produces sintering deposit.The factory building at sintering machine place is called main sintering building under normal circumstances, main sintering building is configured with blending bunker and shop fixtures feed bin above sintering device handpiece, and blending bunker, shop fixtures feed bin top are provided with the transhipment sealing-tape machine from compound conveyor gallery and grate-layer material conveyor gallery.Dust-fall pipe is arranged in below sintering machine, the sinter fume of the pallet bed of material enters dust-fall pipe through bellows, wireway under suction function, Double-deck cinder discharge valve is installed in dust-fall pipe ash bucket bottom, and dust is unloaded to bulk material belt machine by Double-deck cinder discharge valve and transports, as shown in Figure 1.
Sintering machine frame basic platform is positioned at main sintering building and sees below fiery platform, the anchor bolt of sintering machine frame and embedded part are just on this layer of platform, and as shown in Figure 2, both sides, sintering machine frame basis are preformed holes of two air exhaust box wireways, in addition, platform both sides do not have miscellaneous equipment substantially.This layer of platform wireway One's name is legion, each bellows both sides are arranged symmetrically with a pair wireway, and as shown in Figure 3, because in flue gas, dust content is high, granularity of dust is large, makes wireway pipe bent position serious wear, needs regular mending-leakage.In actual production; sintering machine startup-shutdown and fluctuation all can cause wireway bearing temperature to change the thermal stress brought; particularly wireway pipe bent position is except bearing longitudinal dilation matrices; also there is thrust or the pulling force of horizontal direction; easily make weld seam and flange connections distortion, ftracture; cause and leak out, and maintenance work is difficult.
In addition along with metallurgical equipment the Enlargement Tendency, the production capacity of sintering machine is increasing, and the diameter of dust-fall pipe is also increasing. and sintering machine place main sintering building is also built higher and higher. cause the problem of two aspects like this:
On the one hand along with emission request is more and more higher, the volume of head electric cleaner is increasing, head electric cleaner height and length are all in increase, the dust-fall pipe be arranged on below sintering machine needs significantly to climb after going out main sintering building and could dock with the import of head electric cleaner, because large-type sinterer dust-fall pipe is general all more than 4 meters, the turning of dust-fall pipe, climbing adds the resistance of ducting and making, mounting cost.
On the other hand, a lot of large-type sinterer main building head section is highly all more than 40 meters at present. and some even reaches 50 meters, significantly increase height and the length of the vestibule of the vestibule transporting compound and transport grate-layer material, increase construction cost, be unfavorable for that the equipment in these regions is installed and safeguards; Main sintering building height is high, is also unfavorable for the lifting in main building and equipment repair and maintenance.
Summary of the invention
The present invention is directed to existing sintering machine dust-fall pipe and arrange Problems existing, provide a kind of new sintering machine dust-fall pipe arrangement, object reduces flue gas resistance, and minimizing is leaked out, and reduces main sintering building height, optimizes main sintering building arrangement.
The present invention includes: dust-fall pipe is moved to sintering machine frame basic platform both sides below sintering machine, cancel wireway bend pipe and bend pipe lower pipeline, flue gas enters dust-fall pipe with the shortest path, only retain the top straight part of wireway, drastically reduce the area the workload of the making of wireway, installation, maintenance.Owing to eliminating wireway bent tube section, flue gas directly enters dust-fall pipe from bellows through bellows tube connector, expansion joint, wireway (straight tube), wireway length greatly reduces, effectively reduce the resistance of ducting of bellows to dust-fall pipe, cancel wireway elbow simultaneously, the stress that wireway flange, weld seam bear becomes relatively simple, decreases the probability of distortion, cracking.
Dust-fall pipe moves to sintering machine frame basic platform two rear flank, dust-fall pipe center absolute altitude improves relatively, elevation difference between dust-fall pipe export center and head electric cleaner import center reduces, centre-to-centre spacing between two dust-fall pipe becomes large, the spacing at dust-fall pipe center and head electric cleaner import center reduces, dust-fall pipe can be reduced and be exported to duct length between the import of head electric cleaner, increase the radius of turn of pipeline, effectively reduce the resistance of this part pipeline.
Dust-fall pipe is arranged in sintering machine frame basic platform two rear flank, and the absolute altitude of this platform can significantly reduce, and the height of whole like this main sintering building is all reduced.The height being connected to the compound vestibule of main building head, grate-layer material vestibule and relevant transfer station is also reduced.
Traditional sintering machine main factory building is in economic consideration, and sintering machine center line both sides platform one hem width is narrow, and narrow side platform need be taken the circumstances into consideration to external expansion according to dust-fall pipe width by the present invention.
Because sintering machine frame basic platform has flexible gearing and inspection platform respectively in sintering device handpiece both sides, dust-fall pipe should be moved in sintering device handpiece position outside both sides, avoid these devices, the main building both sides of former sintering device handpiece part all need suitably to widen, and main sintering building is seen that fiery platform should be arranged and walked ladder towards flexible gearing.
Dust-fall pipe is arranged in sintering machine frame basic platform two rear flank, takies the position at this platform original sintering machine dry oil lubrication station, so this dry oil lubrication station is configured in sintering machine during actual design to see fiery platform, projected position and original position are substantially identical.
Dust-fall pipe is arranged in sintering machine frame basic platform two rear flank, take the segment space of the hole for hoist in the middle part of this platform sintering machine main factory building, cancel this place's hole for hoist during actual design, transform former tail hole for hoist, daily lifting operation mainly completes at tail hole for hoist.In addition, the hole for hoist of main building head need consider the lifting of flexible transmission device of sintering machine parts.
Dust-fall pipe is arranged in sintering machine frame basic platform two rear flank, and sintering machine frame basic platform absolute altitude reduces, and should shorten central cooler feed chute length, transformation single-tooth roller discharging chute or central cooler frame.
Owing to adopting technique scheme, the present invention cancels wireway bend pipe and bend pipe lower pipeline, reduce wireway length, reduce the length that dust-fall pipe is exported to pipeline between the import of head electric cleaner, increase this place's pipeline turning radius, effective minimizing bellows are to dust-fall pipe, dust-fall pipe is exported to the resistance of ducting between the import of head electric cleaner, reduce main sintering building, compound vestibule, grate-layer material vestibule, the absolute altitude of relevant transfer station, reduce compound vestibule, the length of grate-layer material vestibule, reduce the maintenance workload of wireway, be conducive to main sintering building, the equipment repair and maintenance work of relevant transfer station.
