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

Protrusion and recess mutually splicing, occlusion, pressure, coal surface are to squeeze board support force, the occlusion of two pieces of squeeze boards under support plate
Under power collective effect, two pieces of squeeze boards are expanded to 180 °；
Reduce compacting motor speed, by electric machine shaft driving, gear and double wedge intermeshing act on, compaction rod to coal in coke oven into
Row compacting operation, under the action of limited block, the squeeze board of two pieces of expansion remains at 180 °；When compaction rod downward pressure reaches
When bearing lower pressure or coke oven furnace wall compression resistance to compaction rod maximum, close compacting motor, support plate and squeeze board stop to
Lower movement；
It opens compacting motor to rotate backward, support plate moves up under gear and double wedge intermeshing effect, two pieces of squeeze boards
It is closed in fact again under self gravitation effect, and withdraws from coal loading port of coke oven with support plate；
Step 4), after compaction rod exits the passway where sealing cover, spiral feeder advances to original under hydraulic axis effect
It coalings at position, is disappeared by the traction force that traction rope is connected to sealing cover, the sealing cover on inclined-plane is made in self gravity
It is re-closing off under, is again turned on feed device of coalingging, carry out mending coal operation.
