Description
Technical field
The utility model application casting electric induction furnace, in particular to a kind of dust excluding hood being placed on above electric induction furnace.
Background technique
In foundry enterprise, with the attention that Environmental is protected, the furnace cupola of casting industry is gradually eliminated, induced electricity
Furnace becomes the capital equipment of fusing molten iron.During electric induction furnace melts molten iron, poly- slag skim in operating process, Yi Jitie
In water spheroidizing process, a large amount of dust, smoke pollution will cause.
In order to mitigate or prevent the environmental pollution of workshop flue dust, some electric induction furnace manufacturers install on electric induction furnace
The bell that can be rotated horizontally connects deduster on bell, can effectively prevent the dust pollution generated in fusion process.But bell
The operation such as charging, observation, tapping is affected, is usually dismantled and does not have to by blast-furnace man.Also have above electric induction furnace using horizontal rotation
The dust excluding hood turned, this dust excluding hood, which is equivalent to, vertically have been moved on to bell above electric induction furnace, does not interfere charging, tapping operation,
It is also convenient for molten iron fusing observation, but due to the high temperature action of flue gas and barbarous operation, failure rate is higher.Both dedusting methods without
Method solves the volume of smoke generated when liquid iron balling, and workshop dust pollution is still serious, and advantage is that residue in nodularization packet can be achieved
Molten iron directly melts down.
Also have using slidingtype dust excluding hood as shown in Fig. 1, hang oneself to meet table and transport the requirement of material, using cunning
Movable plate structure.Fixed dust excluding hood 1 is located at the top of electric induction furnace 2, and when table feeding, sliding panel 6 is retracted.When nodularization, overhead traveling crane is hung
Hook 4 hangs nodularization packet 3 and connects tapping molten iron, slides sliding panel 6 at this time, as far as possible covering nodularization flue dust region.But due to wirerope 5
Influence, sliding panel 6 can not all cover nodularization packet.The dust removing effects of this dedusting are bad, always have part flue dust not over
Workshop is sucked out in flue 7.Also have using as shown in Fig. 2, in order to avoid conflicting for steel wire rope of crown block hook and dust excluding hood, and to the greatest extent may be used
Nodularization flue dust can be removed, nodularization packet 3 can be placed in stokehold tapping accident hole or on trolley 8, sliding panel 6 can cover entire ball
Change region, good dedusting effect.After the completion of nodularization, nodularization packet 3 is hung away with overhead traveling crane.Such operation extends the pelletizing operations time,
It is unfavorable for tapping pelletizing operations.The structure and dedusting method of this dust excluding hood, dust removing effects are good.But this slidingtype fixation removes
Dust hood 1, since 3 handling of nodularization packet to the upright position of 2 fire door of electric induction furnace can not be cannot achieve in nodularization packet 3 and be remained by overhead traveling crane
Remaining molten iron melts down, and can only be poured in residual iron slot, is melted down again again after cooling, causes the waste of molten iron heat.
Summary of the invention
The technical issues of the utility model is solved is: providing a kind of fixed dust excluding hood for electric induction furnace, solves day
Vehicle suspension hook wirerope conflicts with dust excluding hood, and structure is simple, facilitates tapping nodularization, the operation such as molten iron melts down.
The technical scheme adopted by the utility model is dust excluding hood is fixedly mounted on to the top of electric induction furnace, it is described to remove
Dust hood is connect by flue with deduster, and in the position directly above of electric induction furnace converter nose, design has strip opening on dust excluding hood
And cover board；Connection stay cord on the cover board pulls drawstring, and cover board rotation is opened, and unclamps drawstring, and cover board is relied on to be self-possessed to be covered with and be opened
Mouthful.
The beneficial effects of the utility model are: dust excluding hood covers entire electric induction furnace and nodularization region, good dedusting effect, knot
Structure is simple, easy to operate, it can be achieved that molten iron melts down, and provides convenience for blast-furnace man, is conducive to improve melting efficiency, reduces melting
Cost.

Specific embodiment
Embodiment 1:
Fig. 3 is the structural schematic diagram of embodiment 1, dust excluding hood 1 is fixedly mounted in the top of electric induction furnace 2, dust excluding hood 1 passes through
Flue 7 is connect with deduster.In the position directly above of the converter nose 11 of electric induction furnace 2, design has strip opening on dust excluding hood 1
10, cover board 9 can cover entire opening 10, and connection stay cord on cover board 9 pulls drawstring, and cover board 9 can be rotated and be opened, and unclamp drawstring,
Cover board 9 can rely on self weight and be covered with opening 10.
When to table feeding, pull drawstring, open cover board 9, as shown in figure 4, the wirerope 5 of overhead traveling crane can pass through opening 10 will
Hopper is sent on table, facilitates blast-furnace man's feeding operation.
When melt operation, drawstring is unclamped, with the covering of cover board 9 opening 10, it can be achieved that all standing dedusting of boiler face.
When nodularization, drawstring is pulled, cover board 9 is opened, slings nodularization packet 3 with crown block hook 4, wirerope 5 will by opening 10
Before nodularization packet 3 is sent to electric induction furnace 2, liquid iron balling is connect.Since dust excluding hood covers entire nodularization packet region substantially, so dedusting is imitated
Fruit is good, and after the completion of nodularization, rapid poly- slag takes off slag operation, advantageously reduces the pelletizing operations time.
If molten iron does not pour in nodularization packet 3, molten iron melt down operation with to table feeding operation it is almost the same.It pulls
Rope opens cover board 9, and nodularization packet 3 can be sent to fire door by opening 10 by the wirerope 5 of overhead traveling crane, by remaining molten iron in nodularization packet 3
It refunds in furnace.
The present embodiment dust excluding hood covers entire electric induction furnace and nodularization region, and good dedusting effect, structure is simple, operation side
Just it, it can be achieved that molten iron melts down, is provided convenience for blast-furnace man, is conducive to improve melting efficiency, lowers melting cost.
Embodiment 2:
Fig. 5 is the structural schematic diagram of embodiment 2, and the present embodiment is the difference from embodiment 1 is that cover board 9 is not covered with entirely
Opening 10, the length of cover board 9 are less than the length of opening 10, are limited with not influencing tapping pelletizing operations, remaining structurally and operationally with
Embodiment 1 is essentially identical.
It is with the maximum difference of embodiment 1, only when molten iron is melted down with table feeding, cover board 9 is just opened, such as Fig. 6
It is shown.In melt operation and pelletizing operations, cover board 9 is still in the state of covering opening 10, reduces in this way than embodiment 1
Opening area further improves nodularization flue dust dust removing effects.
Liquid iron balling can concentrate generation volume of smoke, and this embodiment reduces the opening areas of dust excluding hood when nodularization, than reality
Example 1 is applied with better dust removing effects, while reducing the opening/closing frequency of cover board 9.In the same manner as in Example 1, structure is simple, can be real
Existing molten iron melts down, and provides convenience for blast-furnace man.
