In the formed coke production technology of current comparative maturity, coke oven generally individually adopts vertical type sloping hearth furnace.Traditional top dress is burnt
Stove and tamping coke furnace are typically all not used to produce formed coke, and reason is in traditional coke oven, placement in carbonization chamber for the moulded coal
The drawbacks of mode has very big, moulded coal is packed into during carbonization chamber it is impossible to accomplish uniform piling up, and can waste very long like that
Time can significantly decline in the process of coalingging, furnace temperature, so it is to be all not have Methodistic stacking that moulded coal enters stove.So, moulded coal must
So have with carbonization chamber interior walls substantial amounts of contact, and then moulded coal be changed into formed coke after also can contact in a large number with carbonization chamber interior walls.Type
Burnt hardness is big, intensity is high, so coke pushing can be caused difficult when traditional coke oven is using pusher machine coke pushing, simultaneously hard formed coke with
The a large amount of friction of carbonization chamber interior walls will badly damaged carbonization chamber interior walls, significantly reduce the service life of coke oven, produce and also can be difficult to
It is carried out continuously.Domestic also have using flammable support, that is, using flammable separate layer, moulded coal is layered stacked, places into carbonization chamber combustion
Burn, such technique moulded coal is piled up too loaded down with trivial details with the setting of separate layer, and needs long time to be assisted after the discharging of the coke
Operation, furnace temperature fall can be very big.
Vertical type sloping hearth furnace is exactly the problem of the discharging of the coke in order to solve formed coke.Sloping hearth furnace is exactly furnace bottom as its name suggests is oblique,
Furnace bottom tilts certain angle to coke side, and when formed coke discharges of the coke, due to being wedged bottom, formed coke will be in gravity for such design
In the presence of voluntarily roll out carbonization chamber, discharge of the coke simple and convenient in the extreme, carbonization chamber interior walls will not be damaged, simplified coke oven simultaneously
Machinery, eliminates pusher machine.
Nowadays, the coke oven that domestic most of coke-oven plant adopts is all tamping coke furnace or top shove charge, and the need of formed coke
The amount of asking is increasing, and the production capacity of domestic sloping hearth furnace cannot meet.
Content of the invention

Technical scheme: for achieving the above object, technical scheme is as follows:
Distribution type coal is made firm by ramming and moulded coal tamping coke furnace technique, and processing step is as follows:
A, in charging car, along vertical direction by compactor to load distribution type coal make firm by ramming, obtain upper surface
Distribution type coal briquette for slope shape；
B, upper surface is pushed carbonization chamber for the distribution type coal briquette of slope shape, distribution type coal briquette and carbonization chamber interior walls are formed
Moulded coal is loaded carbonization chamber from carbonization chamber top by the structure of sloping hearth furnace, so that moulded coal is deposited on distribution type coal briquette；
When c, coke are ripe, coke side fire door opens to side, and the burnt gradient by distribution type coal briquette Jiao's upper surface of moulded coal exists
Roll out carbonization chamber in the presence of gravity, after moulded coal Jiao all rolls out, then released burnt for bottom distribution type coal briquette by pusher machine.
Further, length on making direction firm by ramming for the described compactor is linear in the horizontal direction or camber line increases.Make firm by ramming
Hammer makes described distribution type coal firm by ramming trapezoidal shape distribution type coal briquette at a right angle.
Beneficial effect: advantages of the present invention is as follows:
1st, using traditional tamping coke furnace, and manufacturing machine Jiao and formed coke simultaneously in the case of coke oven not being transformed,
Increased the product category of coke-oven plant, the transformation for traditional coke-oven plant provides new thinking；
2nd, compared with other techniques domestic, this technological operation more simple it is not necessary to have extra machinery, material cost throw
Enter；
3rd, distribution type coal is made firm by ramming trapezoidal shape at a right angle, define the structure of similar sloping hearth furnace, solve traditional coke oven formed coke
Coal produces the problem of the coke pushing difficulty in formcoke process.
