Description
Technical field
The invention belongs to metallurgical coking technology field, more particularly to a kind of top fills coke oven coal-charging compacting integrated device and coalings
Debulking methods.
Background technology
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 confession thermit powder of blast furnace, the effect of carbon supplying agenty and reducing agent
Reduced, but coke, used as skeleton, the effect for protecting gas permeability and liquid permeability in blast furnace is strengthened on the contrary, is current blast furnace
Irreplaceable raw material in ironmaking processes.
China's blast furnace metallurgical coke uses chamber type coking process.Existing coking technology is produced with improving coke invariably
Amount, quality expand coal for coking source to reduce production cost, protect limited coking coal resource as starting point.It is above-mentioned to reach
Purpose, main heap density using increase as-fired coal, allocates additive into and realizes using techniques such as dry coke quenching.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 according to the mode of coalingging, heating gas and air feed mode, combustion chamber quirk form, realize it is high to
The difference such as homogeneous heating mode and air-flow regulative mode is classified.Each coke oven form is by reasonable group for classifying above
Close and constitute.There are top dress (in bulk) coke oven and side to fill dividing for (making firm by ramming) coke oven according to the mode coke oven of coalingging.Top dress coke oven is given birth in coking
During product, need in the stage of coalingging the indoor as-fired coal of charing to be carried out being bulldozed process, be commonly called as " flat coal " operation, stay 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 because by itself furnace binding feature, there are the following problems：1、
Because larger the caused carbonization chamber upper and lower part coke quality difference of the upper and lower heap density variation of as-fired coal is big and the burnt product of upper metallurgical
Amount is relatively low；2nd, with the growth in furnace life, the difficulty for improving coke output again in the case of full production is larger；3rd, with height
Stove towards the direction maximized is developed, and the quality of STRENGTH ON COKE is put forward higher requirement, and when Blending does not change, is carried
The difficulty of high coke quality is larger.
Therefore, how the difficulty that coking production is faced is always using existing top dress coke oven raising coke output and quality
Topic.
It is new by looking into, some correlation techniques are retrieved, such as：A kind of " tamping machine of top charging coke stamp-charging coke
(CN2721643Y) " bar shaped pressure head is put into pressures inside by the utility model using leveling bar, then compaction rod and bar shaped pressure
After head connection, leveling bar exits carbonization chamber, and compaction rod is compacted to bar shaped pressure head, and then coke-oven coal is compacted, but patent
In be related to coaling and be compacted it is synchronous carry out, coal charge is entered that charing is indoor by bar shaped pressure head top, and bar shaped pressure head will certainly be to coal
The decline of material produces stop, or even the coal charge for declining can separate bar shaped pressure head with compaction rod connecting portion so that bar shaped pressure head
Fall in coke furnace carbonization chamber, in addition, top dress coke oven coal leveling bar does not have the locomotive function on vertical direction, the utility model
Undeclared that it is reequiped accordingly, after the completion of compacting, the leveling bar that can only be moved horizontally does not have holds bar
Shape pressure head is caused and compaction rod separation function, and then also bar shaped pressure head cannot be held out into carbonization chamber by leveling bar.
" a kind of pressure coal coal leveling device (CN202849318U) of pusher machine " utility model provides one kind not only to be had
Put down logical, smooth, flat balancing function and will can coaling compacting, coaling more, and simple structure, easy replacing, usage cycles length is pushed away
The pressure coal coal leveling device of burnt car.But in whole process, briquetting machine active force is acted predominantly on two blocks of side plates, the work to coal
It is firmly limited, when run into charing in coal surface cross have depression less than leveling bar device or coal surface when, cylinder will hang 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 in top dress
During coke oven coal-charging, will stretch in coke-oven coal with the vibration head for moving up and down function, vibration head is carried out while coalingging and is shaken
It is dynamic.Effect of vibration is possible to that brickwork structure can be damaged, and reduces coke oven service life, easily causes carbonization chamber raw coke oven gas string and drains to
Combustion chamber, and carbonization chamber raw coke oven gas is unprocessed, and Jing combustion chambers can be caused not up to standard eventually through smoke stack emission.In the technology
Tight actual load will be vibrated and be set in coal position under charging car, but clearly do not describe how device is connected with lower device for coal, passed
During the dress coke oven coal-charging of system top, after charging car is aligned with coal port, the horizontal spiral feeder on charging car is in coal loading port of coke oven

Operation simultaneously also counteracts that to a certain extent the blanking of blanking device；Vibration head rises with the rising synchronous of height of coalingging,
That is vibration head is all the time inside the coal of coke oven coal-charging, for existing top dress coke oven coal leveling bar, laterally flat coal operation is generated for this
Very big obstruction, therefore the device does not have the realizability of flat coal operation in production.In addition, coke oven cased coal is typically aqueous
10% or so, can only realize closely knit, the loose coal near vibration head in the range of very little separately through a vibratile thin bar
Powder can not conduct vibration force to very wide range, therefore it is unobvious to improve coke oven coal-charging heap density effect.
" the flat coal method (CN105001884A) of the coke oven " technology provides a kind of coke oven flat coal method, can compress
Coking coal in real coke oven, making the heap density of coking coal increases, and then improves coke quality.Leveling bar external part category in the technology
In hard link, connecting portion causes the leveling bar for stretching out successively can not all make the gravity of itself support force of leveling bar
On coal, therefore, reduce the effect that coal leveling device is compacted to coal.
" coke oven coal leveling device (CN204569810U) " this technology provides one kind and overcome existing top dress coke oven coal leveling bar not
Coke oven coal leveling device in place of foot, using gravity and rolling principle, can layer by layer compress coal charge, flatten.Wherein relate in the technology
And flat coal compaction apparatus part that top layer coal is directly compacted be lever fifth wheel, coal compacting predominant intermolecular forces are come from flat
Support force during coal bar is movable to lever fifth wheel, when coal rat is higher, support force is larger, when coal surface
When there is depression, lever fifth wheel is suspended between leveling bar and coal surface, and support force is obviously reduced, does not even exist, that is,
Say that the lever fifth wheel being connected on leveling bar is acted on and uneven the support force on coal surface, and to the maximum pressure on coal surface
Power is less 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 vibrating compacting function " this technology provides a kind of with vibration
The leveling bar of compacting functions, arranges vibrating compaction device on leveling bar, makes squeeze board produce vibration, profit using Vibration on Start-up device
The purpose put down work of flapping up and down, realize the coal compacting of dress coke oven top is pushed up of squeeze board is realized with quadric chain.But the technology
Vibrating compacting function leveling bar used is due to by leveling bar connection quadric chain effect, there is a big chunk power on vertical direction
Act on the connecting portion of leveling bar and double leval jib；When coal surface occurs uneven, simple vibration can not be realized
The Effective Compaction of coal in coke oven, and the quadric chain vibrator being connected on leveling bar affects to a certain extent leveling bar
Normal walking；In addition, effect of vibration is possible to that brickwork structure can be damaged, coke oven service life is reduced, easily cause charing
Room raw coke oven gas string drains to combustion chamber, and carbonization chamber raw coke oven gas is unprocessed, can cause Jing combustion chambers eventually through smoke stack emission
It is not up to standard.
Therefore, the Density inhomogeneity of coalingging for existing for existing top dress coke oven coal leveling bar device, increase top dress coke oven coke
