Description
Technical field
The utility model relates to coking production technical field more particularly to a kind of top dress make firm by ramming integrated coke oven to coal
System.
Background technique
In China, the coking technology of mainstream is broadly divided into top dress coking by coke oven technology and tamping coke furnace coking technology two at present
Kind, since the high-quality main coking coal resource in China is nervous, under the premise of guaranteeing same weight of coke, tamping coke furnace coking is than top
Dress coking by coke oven at most can polygamy enter 30% weak caking coal, reduce coking production cost.But top dress coke oven is relative to smashing
Gu coke oven has many advantages, such as that simple production process, coke oven for iron maintenance are small, based on the above reasons, more and more coal chemical enterprises
Tending to selection not only can be carried out tamper production, but also can be carried out the coke oven of top dress production, and after the coke oven for configuring this form, enterprise can
According to factors such as market conditions, coal resources, the switching of top dress coking by coke oven and tamping coke furnace coking production model, production are carried out
Mode is more flexible, and can increase the economic benefit of enterprise.
The top of top dress coke oven coaling tower be typically located between two coke ovens between above platform, on the top that oven top of coke oven moves
Dress charging car can be directly entered top and coaling tower received down furnace coal, and the coal tamping tower of tamping coke furnace is typically located between coke oven
The pusher side of platform, while coal tamping tower received down furnace coal, the tamping unit of coal tamping tower setting will be smash tamping charging car
Gu the furnace coal in case is pounded briquette.For having top dress to make the coke oven coal supply system of function firm by ramming simultaneously, have disclosed at present
Technical solution is to be respectively set that feed opening is coaling on several groups of tops and several groups of coal tamping feed openings, furnace roof are coaling in top tower bottom of coalingging
Vehicle, which can be directly entered top, coalings to coaling from top below tower and receives furnace coal from feed opening, is arranged below coal tamping feed opening and fixes
Coal tamping is delivered to coal tamping tower by transporting coal belt feeder, and mutually not general between two kinds of feed openings, this is just that coke oven production mode is cut
Following problem is brought when changing：
(1) when coke oven is in top dress coke oven production mode, being stored in the coal near coal tamping feed opening can not be unloaded down, shape
At dead zone, if the long period switches without production model, the coal near coal tamping feed opening is easy hardened, and blocking is made firm by ramming
Coal feed opening.When coke oven is from top dress production model to tamper production pattern switching, due to the coal plate near coal tamping feed opening
Knot, feed opening being blocked are then needed to spend a large amount of cleaning of artificial and time feed openings, be made troubles to production model switching.Similarly
When coke oven switches from tamper production mode to top dress production model, similar trouble can be also encountered.
(2) no matter which kind of production model coke oven is in, since the coal near another production model coal feed opening is formed extremely
Area becomes smaller so that coal tower obtains dischargeable capacity, and the practical coal storage ability of coal tower is caused to become smaller.
Summary of the invention
The utility model provides a kind of coal supply system for pushing up dress and making integrated coke oven firm by ramming, can satisfy top dress and makes firm by ramming
The demand of two kinds of production models, and the furnace coal in coal tower will not be formed about dead zone in feed opening, avoid feed opening because of coal
Flitch knot and block, while increasing the dischargeable capacity of coal filling tower.
