Description
Technical field
It can adapt to top dress the utility model relates to coking by coke oven technical field more particularly to one kind and make integrated coke oven firm by ramming
The defeated coal cloth screw conveyor of movable type switched to coal.
Background technique
Since tamping coke furnace coking can more be incorporated the low binding coal of high volatile or non-adherent than top dress coking by coke oven
Property coal, makes tamping coke furnace coking have wider coal source.As production spirit improves in the growing tension of coking coal resource and coke-oven plant
Active requirement, top dress makes integrated coke oven firm by ramming or top dress coke oven changes top dress and makes the market demand of integrated coke oven firm by ramming and constantly increases
Greatly.On top, dress is made firm by ramming in integrated coke oven coal preparation technology, how to be realized top dress, is made furnace coal in two kinds of different production methods firm by ramming
It is key problem in technology place to coal switching.
Currently, country top dress, which makes integrated coke oven furnace coal firm by ramming, is all made of the side that coal mouth under tower of coalingging is pushed up in switching to coal switching
Formula is realized.Such as the Chinese patent of Publication No. CN103992803A, disclose that " one kind can produce stamp-charging coke but also production top
Fill burnt coke oven for iron ": it is provided with two kinds of funnel groups in the case where tower is coaling on top, respectively corresponds coal and tamping coking under the dress coking of top
Lower coal pushes up coaling tower tamping coking funnel group and side-mounted tamping coal tower to fix belt conveyor connection；Publication No.
The Chinese patent of CN107298981A, disclose " a kind of top 7.3m dress makes dual-purpose type coke oven production technique firm by ramming ": it coalings on top
Tower divides into top set and coalings coal mouth under lower coal mouth and coal tamping, with fix belt conveyor connection top coaling under tower coal tamping coal mouth and
Coal tamping tower realizes that top dress makes switching to coal for two kinds of furnace coals firm by ramming.Although above-described two kinds of technical solutions are able to achieve top
Dress makes switching to coal for two kinds of furnace coals firm by ramming, but has the disadvantage that
(1) it when top dress coking or tamping coking, in above-described two kinds of technical solutions, is under one kind of coal tower
The idle state of the production of coal mouth, another lower coal mouth, thus greatly reduces the utilization rate for pushing up coal mouth under tower of coalingging.
(2) since feed coal accumulates in the top coal scuttle of coal mouth under leaving unused, " dead coal " is formed after hardened, reduces coal tower
Available capacity, to guarantee coal tower available capacity, investment will be increased by, which being bound to, increases coal tower；In addition, the switching of coking by coke oven mode by
The factors such as coal, market restrict, the period is longer (several months to several years), in coal scuttle long-standing " dead coal " Yi Fasheng spontaneous combustion is even
Explosion, considerably increases security risk.
(3) coal mouth and coal tamping tower under tower of coalingging are pushed up using fixed belt conveyor connection, the height of tower so that top is coaling
The space requirement of coalingging of top dress charging car and fixed belt conveyor could be met simultaneously by least needing to raise 3~4m, be increased
The investment of coal handling system before coal tower and coal tower.
Coke oven top dress was not only met it can be seen that how to realize, has made switching to coal for two kinds of furnace coals firm by ramming, but also can be sufficiently sharp
With the capacity of existing coal tower and the above deficiency is avoided, becomes and improves the pass that top dress makes integrated coke oven coal preparation technology economy firm by ramming
Key.
Summary of the invention
The utility model, which provides a kind of top dress, makes integrated coke oven firm by ramming and gives coal movable type defeated coal cloth screw conveyor,
As needed, removable screw conveyor can be erected to coal tower and making firm by ramming to be realized between coal scuttle to making firm by ramming in coal scuttle into coal,
Or coal tower lower space is conceded into top dress charging car into coal, thus meet coke oven top dress, make firm by ramming two kinds of furnace coals to coal
The characteristics of switching has structure simple using helical feed mode, and closure is good, reliable operation.
In order to achieve the above object, the utility model is implemented with the following technical solutions:
Top dress makes integrated coke oven firm by ramming and gives coal mobile defeated coal cloth screw conveyor, including removable screw conveyor
And walking rails；The removable screw conveyor is made of closed box, conveyor screw, rack and running mechanism；Rail
