The compositions such as clock, bottom bell, device for discharging and execution connecting rod.
On the one hand top charging apptss are the passages of charging blast furnaces, on the other hand after charging end-of-job, are also played
The sealing function of furnace gas in whole stove.During charging, sling batch can by charging crane, when batch can is fitted with device for discharging upper flange
When, top bell is opened, and material falls in batch can, rests on bottom bell top, is then shut off top bell, then opens bottom bell,
After material fully enters internal blast furnace, bottom bell is closed, and thus completes a charging action.But batch can and device for discharging
Upper flange faying face is by long-term collision, deformation, when the material in batch can falls into the top of bottom bell with the unlatching of top bell
When, before top bell is also not closed, there are part small grain size material and dust excessive from this, not only cause the damage of valuable metal
Lose, and cause that site environment is deteriorated.
When damping down cleaning work is carried out to blast furnace, the power-equipment of blast furnace rear portion system is stopped, this is caused
Furnace high-temperature gas nowhere discharges, and then the directly mechanism such as erosion, baking, calcination top bell, bottom bell, execution connecting rod, so that
Top charging apptss are damaged, causes top bell, bottom bell to open difficult or seal failure.In order to avoid case above, it is necessary to fixed
Shi Kaiqi top bells and bottom bell, by the high-temperature furnace gas release in blast furnace.At this moment there are a large amount of inner flue gas of the stove excessive, cause valuable
Metal largely loses, metal recovery rate reduction.A large amount of excessive flue gases, not only corrode surrounding structures, facility etc., and scene
Environment is deteriorated, and is unfavorable for cleaning the development carried out production strictly in line with rules and regulations and worked with safety and environmental protection, is also unfavorable for that employee is physically and mentally healthy.
The content of the invention
For defect of the prior art, the present invention provides a kind of simple structure, good leak tightness and recyclable inner flue gas of the stove
Top filling device for blast furnace.
The utility model is achieved through the following technical solutions：
A kind of top filling device for blast furnace, including main body, top bell, bottom bell, device for discharging and execution connecting rod, it is described
Top bell is arranged on body top, and the bottom bell is arranged on lower body part, and device for discharging is arranged on the top bell top, institute
Stating device for discharging includes funnel type main body, and the infundibulate main body upper end is provided with upper flange, and bottom is provided with and the main body
With reference to lower flange, the lower flange is fixedly connected by supporting walls with the funnel type main body；It is characterized in that：Also include receiving
Dirt device, the dust arrester installation includes house steward of gathering dust, and is negative pressure in the house steward's pipe that gathers dust, and the house steward of gathering dust passes through embedded institute
State the first air draft pipe of supporting walls and the inner space of the device for discharging；The house steward of gathering dust connects second by rotor
One end of air draft pipe, the other end of second air draft pipe connects the cover body that gathers dust, and is provided with second air draft pipe
Valve.
More specifically, in the device for discharging, described lower flange the inner is provided with inner support wall, outside is additionally provided with outer branch
Support wall, is provided with least two passages on the inner support wall, first air draft pipe is embedded in the outer support wall.
To ensure rotor uniform force so that the second air draft pipe and the cover body that gathers dust rotate flexible, can be described the
Chain is set on two air draft pipes, rotor uniform force is ensured by adjusting the chain elasticity, rotate flexible, the chain
Bar one end is fixed at the second air draft pipe, and the other end is fixed on rotor, is preferably fixed in a certain fixed point of the centre of gyration.
A kind of top filling device for blast furnace of the present utility model, during daily production charging, the material in batch can
As the unlatching of top bell is during the top for falling into bottom bell, tiny dust, flue gas, from funnel type main body lower port
Outside through embedded supporting walls the first exhaust column, by gathering dust, house steward collects.
During damping down is cleared away, by using rotor, the cover body that will gather dust manually is rotated to directly over device for discharging, is opened
Valve, you can realize flue gas dust collection operation.In blast furnace routine work, the cover body that will be gathered dust manually by using rotor leaves
Device for discharging top, and close valve.
The device can effectively collect inner flue gas of the stove, the dust overflowed during charging process and damping down cleaning so that in flue gas
Metal be able to reclaim and effectively improve the working environment around blast furnace.
