Abstract
The utility model discloses a kind of detachable dust excluding hood of blast furnace iron notch, which is made of cover top, side plate, panel, column, crossbeam, locating piece, hook, suspender, lifting lug, operation inlet and outlet, gusset.Cover top is placed on crossbeam, is positioned by locating piece at the top of column；Crossbeam is fixed on column, and column is fixed on blast furnace iron notch platform；By the hook of column side, side plate and panel can be positioned at column side；Suspender is fixed on cover top top, and lifting lug is fixed on side plate and upper panel；For operation import and export in lower panels, gusset is weldingly fixed on cover top/bottom part.The cover top of the device, side plate and panel are can to dismantle, and neither influence equipment operation and maintenance in this way, and when molten iron discharging can form enclosure space again, and raising dust arrestment rate reduces the pollution to environment, failure rate is low, simple and reliable practicality.
Description
Technical field
The utility model is related to a kind of dust-extraction unit more particularly to a kind of detachable dust excluding hoods of blast furnace iron notch.
Background technology
Blast furnace discharge yard smoke contamination is serious, often generates 1t iron, about generates 2.5kg flue dust.Tapping hole is dissipated in cast house
The main flue dust source for sending out pollutant, accounts for about the 30% of gross contamination object, carries out effective dedusting of tapping hole, to improving blast furnace blast-furnace man
Make condition, reduces flue dust and play an important role to the pollution of air.Blast furnace iron notch mostly uses the mode that side is inhaled plus top suction is combined,
Also there is top draft hood at scene.In order to protect the normal use of iron mouth machine and clay gun, top draft hood is higher apart from tapping hole, smoke catching effect
Difference.Since tapping hole is open space, surrounding air can be rolled up inspiration and gone by wind turbine, increase the inspiratory capacity of wind turbine, power consumption it is big and
Smoke catching effect is poor.Flue dust spreads escape in uphill process simultaneously, when cast house has lateral wind or tapping hole to spray
When splashing, high pressure flue gas can go out smoke catching area, easily cause the generation of flue dust out-of-control phenomenon.Fixed dust excluding hood can influence
The operation of iron jaws equipment and maintenance of equipment, removable or rotatable petticoat pipe are easy by high-temperature smoke due to closer from tapping hole
Wash away, equipment failure rate is high, short life, and when there is lateral wind, collects flue dust poor effect.
Invention content
The utility model is intended to overcome the existing defect of dust hood for blast furnace tap hole, and it is detachable to provide a kind of blast furnace iron notch
Dust excluding hood, efficiently to complete the task of blast furnace iron notch smoke catching.The utility model dust excluding hood includes：Cover top, side plate, face
Plate, column, crossbeam, locating piece, hook, suspender, lifting lug, operation inlet and outlet, gusset.It is lifted by live overhead traveling crane, cover top is placed on
On crossbeam, positioned by locating piece at the top of column；Crossbeam is fixed on column, and column is fixed on blast furnace iron notch platform
On；By the hook of column side, side plate and panel Liftable are positioned at column side；Suspender is fixed on cover top top, lifting lug
It is fixed on side plate and upper panel.For operation import and export in lower panels, gusset is weldingly fixed on cover top/bottom part.
Wherein cover top is washed away by high-temperature smoke, and in order to avoid deforming, proof strength, cover top is welded by steel plate makes
Make, while cover top/bottom part staggeredly welds gusset, refractory cotton can be also embedded between gusset, cover top can dismantle.
Its latus inframedium is washed away smaller by high-temperature smoke, and main function is to form confined space, reduce wind turbine inspiratory capacity and
Lateral wind effect.Side plate is made of angle steel and aluminium sheet, and aluminium sheet is riveted on angle steel, can dismantle.
Wherein panel is made of angle steel and aluminium sheet, and aluminium sheet is riveted on angle steel, can dismantle.
Its central post is made of I-steel, and bottom is weldingly fixed on blast furnace iron notch platform, the spacing between column
Guarantee does not influence tapping hole equipment operation and maintenance of equipment, while reaching intensity requirement again.
Its middle cross beam is made of I-steel, is bolted on column, and the spacing and height of crossbeam ensure not shadow
Tapping hole equipment operation and maintenance of equipment are rung, while reaching intensity requirement again.
Wherein locating piece is made of angle steel, is weldingly fixed at the top of column, convenient for the lifting positioning of cover top.
Wherein hook is made of angle steel, is weldingly fixed on column side, convenient for side plate and panel lifting positioning.
Wherein suspender is made of steel pipe and steel plate, is weldingly fixed at the top of cover top, convenient for overhead traveling crane lifting cover top, avoids people
Work lifts.
Wherein lifting lug is made of square steel, is weldingly fixed at the top of side plate and panel, and side plate and panel are lifted convenient for overhead traveling crane,
It avoids manually lifting.
Wherein operation inlet and outlet are located at lower panels, and personnel easy to operation pass in and out petticoat pipe operation.
Wherein gusset is made by steel plate, is welded in cover top/bottom part, improves cover top intensity, while convenient for embedded refractory cotton.
Due to the adoption of the above technical scheme, utility model device has following good effect compared with the prior device：
1. the utility model is simple and practical, can make, it is cost-effective；
2. the utility model is detachable, i.e., equipment operation is not influenced, also improves dust arrestment rate；
3. the utility model is simple in structure, service life is long, and securely and reliably, failure rate is low.
Therefore, the utility model has the advantages of simple structure and easy realization, and is simple and efficient, securely and reliably.

Specific implementation mode
Practical patent is described further below in conjunction with the accompanying drawings：
The dust excluding hood of the utility model is by cover top 1, side plate 2, panel 3, column 4, crossbeam 5, locating piece 6, hook 7, suspender
8, lifting lug 9, operation inlet and outlet 10, gusset 11 forms.When it is implemented, the dust excluding hood of the utility model is mounted on blast furnace iron notch
Locate, trough is closed in dust excluding hood at tapping hole and tapping hole；It is closed by cover top 1 at the top of dust excluding hood, dust excluding hood is towards going out
Part is closed by blast-furnace body at iron mouth, and side has side plate 2 and panel 3 to close；Dust excluding hood is just formed close when normal blast furnace casting
Space is closed, dust arrestment rate can be improved.The wherein cover top 1 of dust excluding hood, side plate 2 and panel 3 are detachable, equipment need operation or
, can be by live overhead traveling crane, by cover top 1 when person overhauls, side plate 2 and panel 3 are dismantled, and are returned dress when tapping a blast furnace again, are passed through suspender 8 and lifting lug
9, it need not manually lift.
