Description
Technical field
The utility model relates to coke oven technical field more particularly to a kind of nested type coke oven combustion chamber-chute structures.
Background technique
With the development of coking technology, coke oven enlargement is trend of the times.But to realize that coke oven enlargement is not only
The amplification of coking furnace shaft size equal proportion is so simple, but needs to carry out rational modification to coking furnace shaft structure, can fit
Answer the requirement of enlargement.For example, to meet the high to heating uniformity of coke oven after enlargement, Patent No. CN10251742B's
Chinese patent discloses " a kind of coke oven heating method of controllable multi-section-combustion ", proposes coke oven grading combustion technology.But
There is no the intensity for considering furnace wall limit side load and furnace wall whether can satisfy requirement for it.
Coke oven enlargement is not only increase of the coke oven height to size, coke oven length to and width direction size all
Increase.The coke oven of enlargement can be realized the raising of coal capacity and coke output, but due to the increase of coal amount, coke coking
The bulbs of pressure of coking chamber wall and coke pushing resistance are also accordingly increased in journey；Therefore, the intensity of coking chamber wall is wanted
It asks and is consequently increased.
It as shown in Figure 1-Figure 3, is domestic currently used oven wall of coke oven carbonization chamber structure, wherein the shop fixtures in combustion chamber
It is only connected by bridge of the nose brick 4 and lamp cap brick 3 between brick 2 and chute 5, this structure can satisfy the intensity of small scale coke oven production operation
It is required that but for capacity coke oven, it is smaller due to being mutually twisted contact surface, cause furnace wall structure intensity relatively low, therefore
It is unable to satisfy requirement.In addition, there are horizontal mortar joints between its carbonization chamber and combustion chamber, string leakage is easily caused.
Summary of the invention
The utility model provides a kind of nested type coke oven combustion chamber-chute structure, protrudes into combustion by chute boss brick
It burns room and forms combustion chamber-chute nested structure, effectively improve coking chamber wall intensity；And it is not present between carbonization chamber and combustion chamber
Horizontal mortar joint will not cause string to leak.
In order to achieve the above object, the utility model is implemented with the following technical solutions：
A kind of nested type coke oven combustion chamber-chute structure, the combustion chamber are set by combustion chamber stove walled, combustion chamber
Lower section sets chute for being connected to regenerative chamber；Bottom of combustion chamber sets chute mouth, and chute is formed by multilayer chute brick masonry；Top
Chute brick part extends upwardly in combustion chamber, forms chute boss brick, combustion chamber is connected in nested fashion with chute
Together；Combustion chamber furnace wall bottom first layer brick is made of furnace wall interconnecting piece and shop fixtures portion, and wherein shop fixtures portion extends in combustion chamber,
Furnace wall interconnecting piece and shop fixtures portion are integrally built by refractory material；The top surface of furnace wall interconnecting piece is higher than the top surface in shop fixtures portion, paving
The top surface of bottom is identical as the apical side height of chute boss brick.
The chute mouth is enclosed to set by chute boss brick to be formed.
The width in the shop fixtures portion is adjusted according to the taper of coke oven.
Compared with prior art, the utility model has the beneficial effects that：
1) chute boss brick, which is equivalent to, combines the brick in conventional structure around chute bridge of the nose brick with bridge of the nose brick, makees
Directly go deep into combustion chamber for a part of combustion chamber shop fixtures brick, plays a supporting role to combustion chamber furnace wall；
2) combustion chamber furnace wall bottom first layer brick is made of furnace wall interconnecting piece and shop fixtures portion, and it is whole build forming, and it is oblique
The cooperation of road boss brick, avoids the straight-through seam in conventional structure between carbonization chamber and combustion chamber shop fixtures brick, to enhance charing
The structural strength of room furnace wall and the globality of coking furnace shaft and leakproofness；
3) structure is simple, easy for construction, it is easy to accomplish engineering.
