Description
Technical field
The invention belongs to metallurgical coking technology field, in particular to a kind of top dress coke oven coal-charging is compacted integrated device and coalings
Debulking methods.
Background technique
With the continuous development and raising of blast furnace smelting technology and equipment, the requirement of blast furnace Coke Quality is more and more tight
Lattice, although the development of oxygen enriched blast coal injection new technology etc., coke has as the effect for thermit powder, carbon supplying agenty and reducing agent of blast furnace
It is reduced, but coke protects the effect of gas permeability and liquid permeability in blast furnace to be reinforced instead, be current blast furnace as skeleton
Irreplaceable raw material in ironmaking processes.
China's blast furnace metallurgical coke is using chamber type coking process.Existing coking technology is invariably to improve coke production
Amount, quality expand coal for coking source to reduce production cost, the limited coking coal resource of protection as starting point.It is above-mentioned to reach
Purpose, it is main to be realized using techniques such as the heap density, supplying additive and the application dry coke quenching that increase as-fired coal.Increase coal charge heap
The measure of density includes improving carbonization chamber height, coal conditioning technique, tamping technology and with shaped coal technology etc..
Modern coke oven can be fed according to the mode of coalingging, heating gas and air mode, combustion chamber quirk form, realize it is high to
The differences such as homogeneous heating mode and air-flow regulative mode are classified.Each coke oven form is by reasonable group to classify above
It closes and constitutes.It there are top dress (in bulk) coke oven and side dress (making firm by ramming) coke oven according to the mode coke oven of coalingging.Top dress coke oven is raw in coking
It during production, needs to carry out as-fired coal in carbonization chamber in the stage of coalingging to be bulldozed processing, is commonly called as " flat coal " operation, is stayed after coalingging
Under angle of rest (repose) be bulldozed, with reach increase coke oven coal-charging amount, improve coke output purpose.
In actual coking production process, top dress coke oven is since by itself furnace structure feature, there are the following problems: 1,
Above and below as-fired coal heap density variation it is larger caused by carbonization chamber upper and lower part coke quality difference is big and the burnt production of upper metallurgical
It measures lower；2, with the growth in furnace life, the difficulty for improving coke output again in the case where full production is larger；3, with height
The direction of furnace towards enlargement is developed, and more stringent requirements are proposed for the quality of STRENGTH ON COKE, when Blending does not change, mentions
The difficulty of high coke quality is larger.
Therefore, how coke output is improved using existing top dress coke oven and quality is always the difficulty that coking production is faced
Topic.
It is new by looking into, some the relevant technologies are retrieved, such as: a kind of " tamping machine for pushing up charging coke stamp-charging coke
(CN2721643Y) " bar shaped pressure head is put into pressures inside using leveling bar by the utility model, then compaction rod and bar shaped pressure
After head connection, leveling bar exits carbonization chamber, and compaction rod is compacted bar shaped pressure head, and then coke-oven coal is compacted, however patent
In be related to coalingging it is synchronous with compacting carry out, coal charge is entered in carbonization chamber by bar shaped pressure head top, and bar shaped pressure head will certainly be to coal
The decline of material generates blocking, or even the coal charge of decline can separate bar shaped pressure head with compaction rod connecting portion, so that bar shaped pressure head
It falls into coke furnace carbonization chamber, in addition, top fills coke oven coal leveling bar and do not have the locomotive function on vertical direction, the utility model
Undeclared to be reequiped accordingly to it, after the completion of compacting, the leveling bar that can only be horizontally moved simultaneously does not have and holds item
Shape pressure head make with compaction rod separation function, and then also bar shaped pressure head cannot be held out carbonization chamber by leveling bar.
A kind of " pressure coal coal leveling device (CN202849318U) of the pusher machine " utility model, which provides one kind, not only to be had
Flat logical, smooth, flat balancing function and the compacting that can will coaling, coaling, and structure is simple more, Yi Genghuan, and service life is long to be pushed away
The pressure coal coal leveling device of burnt vehicle.But in the whole process, briquetting machine active force acts predominantly on two blocks of side plates, to the work of coal
It is firmly limited, when encounter carbonize in coal surface cross have recess lower than leveling bar device or coal surface when, roller will be hung on
Between coal leveling device and coal surface, coal surface no pressure is acted on.
A kind of " method and device (CN105713623A) for the improving top dress coke oven coal-charging heap density " patent is filled on top
When coke oven coal-charging, will there is the vibration head for moving up and down function to stretch in coke-oven coal, vibration head vibration is carried out while coalingging
It is dynamic.Effect of vibration is possible to that brickwork structure can be damaged, and reduces coke oven service life, carbonization chamber raw coke oven gas string is easily caused to drain to
Combustion chamber, and carbonization chamber raw coke oven gas is unprocessed, will cause through combustion chamber eventually by smoke stack emission without up to standard.In the technology
Close actual load will be vibrated and be set in coal position under charging car, but there is no clearly narration devices how to connect with lower device for coal, passes
When the dress coke oven coal-charging of system top, after charging car and coal port contraposition, the lateral spiral feeder on charging car is in coal loading port of coke oven

That is vibration head, always inside the coal of coke oven coal-charging, for existing top dress coke oven coal leveling bar, laterally flat coal operation is produced for this
Very big obstruction, therefore the device and the realizability for not having flat coal operation in production.In addition, coke oven cased coal is generally aqueous
10% or so, closely knit, the loose coal of vibration head nearby very a small range can only be realized separately through a vibratile thin bar
Powder can not conduct vibration force to very wide range, therefore improve coke oven coal-charging heap density effect and be not obvious.
" the flat coal method (CN105001884A) of the coke oven " technology provides a kind of flat coal method of coke oven, can compress
Coking coal in real coke oven increases the heap density of coking coal, and then improves coke quality.Leveling bar extension end belongs in the technology
In hard link, connecting portion make the leveling bar successively stretched out can not all the gravity of itself support force of leveling bar
With on coal, therefore, the effect that coal leveling device is compacted coal is reduced.
" coke oven coal leveling device (the CN204569810U) " technology provides one kind and overcomes existing top dress coke oven coal leveling bar not
The coke oven coal leveling device of foot place using gravity and rolls principle, can compress layer by layer coal charge, flatten.Wherein related in the technology
And flat coal compaction apparatus part that surface layer coal is directly compacted be lever fifth wheel, to coal compacting predominant intermolecular forces from flat
To the support force of lever fifth wheel during the back-and-forth motion of coal bar, when coal surface bulge is higher, support force is larger, when coal surface
When being recessed, lever fifth wheel is suspended between leveling bar and coal surface, and support force is obviously reduced, is even not present, that is,
Say that the lever fifth wheel that is connected on leveling bar to the support force effect on coal surface and uneven, and presses the maximum on coal surface
Power is no more than the support force in leveling bar traveling process to lever fifth wheel, and mass action effect is limited.
A kind of " leveling bar (CN105885878A) with the vibrating compacting function " technology provides a kind of with vibration
The leveling bar of compacting functions, is arranged vibrating compaction device on leveling bar, so that squeeze board is generated vibration, benefit using starting vibrator
The upper and lower flat work of flapping that squeeze board is realized with four-bar mechanism is realized the purpose of coal compacting at the top of the dress coke oven of top.But the technology
Vibrating compacting function leveling bar used has a big chunk power on vertical direction due to being acted on by leveling bar connection four-bar mechanism
Act on the connecting portion of leveling bar and double leval jib；When coal surface occurs uneven, simple vibration be can not achieve
The Effective Compaction of coal in coke oven, and the four-bar mechanism vibrator being connected on leveling bar influences leveling bar to a certain extent
Normal walking；In addition, effect of vibration is possible to that brickwork structure can be damaged, coke oven service life is reduced, charing is easily caused
Room raw coke oven gas string drains to combustion chamber, and carbonization chamber raw coke oven gas is unprocessed, will cause through combustion chamber eventually by smoke stack emission and
It is not up to standard.
