Specific embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation, it is therefore an objective to help those skilled in the art to the design of the utility model, technical solution have it is more complete, accurate and
Deep understanding, and facilitate its implementation.
As shown in Fig. 1 to Figure 18, a kind of coke dry quenching furnace high temperature flue refractory masonry structure, including refractory masonry sheet
Body, between refractory masonry ontology and external expansion section shell be filled with sealing thermal insulation cast bed of material 1, refractory masonry ontology include by
Under to the bottom masonry, side wall and top masonry for being above sequentially connected setting, bottom masonry, side wall and top masonry are enclosed cigarette
Gas channel.Top masonry is preferably arch masonry, and sound construction can effectively extend the service life of high temperature channel.
For low, easy to fall off, the service life the is short problem of coke dry quenching boiler entrance high temperature channel castable structural strength, this reality
Refractory brick marshalling structure is combined with new design arch, sound construction has the characteristics that high temperature resistant, is wear-resistant, can be effective
Extend the service life of high temperature channel.The refractory masonry structure is wanted according to geometry, the wear-resisting, high temperature resistant of high temperature channel
It asks, designs two sides and bottom using refractory brick anchoring masonry, top and use arch masonry, refractory masonry and external stainless steel expand
It is poured between section shell using heavy castable closely knit.Specifically, coke dry quenching boiler entrance high temperature channel masonry structure and point
Class brick is as follows:
The masonry brick of arch masonry is axe brick 2 wide at the top and narrow at the bottom.Specifically, using model GAM- in arch crown part
1579 axe brick, GAM-1579 brick be mullite material production, shape be it is wide at the top and narrow at the bottom, guarantee that brick body is agreed with securely.As
A kind of preferred implementation ratio setting, as shown in figure 4, the ratio of axe brick width both ends width and width both ends wire length is
107:97.5:416, as shown in figure 5, Aspect Ratio is 416:230.In order to reinforce the secured intensity of arch masonry, built at top
Body (arch masonry) setting locking brick, locking brick can be increased locking effect, be prevented from falling off using multiple.
Side wall is connect with the linkage section of arch masonry using special-shaped occlusion structure brick.The linkage section of side wall and vault masonry is logical
Cross three kinds of special-shaped occlusion structure brick connections, the special-shaped occlusion structure brick of the first of respectively model GAM-1571, model GAM-1569
The second special-shaped occlusion structure brick and model GAM-1575 third abnormity occlusion structure brick.Special-shaped occlusion structure brick, which designs, to be adopted
It is made of mullite material.The both ends of vault masonry are connect with third abnormity occlusion structure brick masonry respectively, the first abnormity occlusion
Similar to being L-type structure brick, third abnormity occlusion structure brick is two tapered points of removal for structure brick and the second special-shaped occlusion structure brick
The end face of the triangular structure of right angle in corner, removal acute angle corner is horizontal plane, and two horizontal planes are respectively parallel to two
Right-angle side, two horizontal planes are connected by inclined surface, and the both ends of the surface of vault masonry are engaged knot with third abnormity in both walls respectively
The inclined surface of structure brick builds connection, so that the downward power in vault part passes through the linking peptizaiton of inclined surface, reduces vault pair
The direct extruding of side wall reduces the proportion of goods damageds.First special-shaped occlusion structure brick and the second special-shaped occlusion structure brick occlusal masonry are in side
On wall, implementation ratio setting as one preferred, as shown in fig. 6, Aspect Ratio is 288:133.5, as shown in fig. 7, first
The whole height of special-shaped occlusion structure brick and the ratio of L-type cut height are 133:38；As shown in figure 8, Aspect Ratio is 230:
113.5, as shown in figure 9, the whole height of the second special-shaped occlusion structure brick and L-type cut height and the wide ratio of notch short side are
180:133:100, as shown in FIG. 10 and 11, the ratio of length, width and height is 405:113.5:295, and the length ratio of two horizontal planes is
72:39.5。
Side wall is built using side wall brick 9, in sidewall structure, erects (height) to every several layers of several anchored bricks of design, anchor
Gu turning to use GAM-1568 brick；Anchoring brick equally selects mullite material, by the setting of anchored brick, further increases it
Structural integrity effectively extends the service life of high temperature channel.
Side wall is located at the basic straight section on the masonry of bottom and is equipped with reinforcing brick 6.Reinforcing brick 6 is ten layers, reinforces brick and uses GAM-
1573 bricks, material selection mullite material.Specifically, the basic straight section of both walls, which is built, reinforces brick, further improve
Its structural integrity.
Bottom masonry includes bottom brick layer and the reinforcing brick layer on bottom brick layer.Reinforcing brick layer positioned at bottom masonry upper layer
Using GAM-1573 brick, with the reinforcing brick number of side wall basis straight section, below three layers be bottom brick 8, using GAM-
Mullite material is used in S101 brick, the selection of brick material.
It is poured between refractory masonry and external stainless steel expansion joint shell using heavy castable closely knit；Castable material is
Heavy castable (trade mark ZCH).
The utility model also provides the building method of the coke dry quenching furnace high temperature flue refractory masonry structure, this method
It is to pass sequentially through set up job platform, castable of disintegrating, cut off anchoring piece, clear up furnace shell, build both walls, install masonry arch
Tire, between building arch crown refractory brick, pouring using heavy castable closely knit refractory masonry between external stainless steel expansion joint shell
Gap and dismounting masonry arch tire obtain the refractory masonry structure, finally clean health in furnace.Certainly, set up job platform it
Before, it first has to remove high temperature channel position castable, convenient for the progress of follow-up work.
Specifically, vault building method: arch crown part uses GAM-1579 brick, and GAM-1579 brick turns for axe, upper width
Under it is narrow；Vault builds the method for using the preparatory supporting of wooden model, and to prevent vault faulting of slab ends, arch tire must be installed securely；Vault is built
When last arch brick, while squeezing into three blocks of neck bricks；Arch top needs bracing wire to be built, to guarantee the flatness of masonry.
The brick building method of side wall: it is different that with vault linkage section GAM-1569, GAM-1571 and GAM-1575 is respectively adopted in side wall
Type occlusion structure brick by being built as shown in Figure 1；Side wall rule position uses GAM-S101 brick, and anchored brick uses GAM-1568
Brick, side wall basis straight section use GAM-1573 brick.Using these above-mentioned brick, formed according to being built shown in Fig. 1.
The brick building method in bottom: bottom upper layer use GAM-1573 brick, below three layers use QN53-S101 bricks, pass through block
It builds to build bottom masonry and form.
Heavy castable fills gap: irregular between vault masonry and top shell, between side wall and furnace body shell
Region is filled using high alumina castable (ZCH-027 type), enhancing heat preservation and sealing function.Specific physical and chemical index design is as follows
Table.
The utility model is exemplarily described in conjunction with attached drawing above.Obviously, the utility model implements not
It is limited by aforesaid way.As long as the various unsubstantialities that the method concept and technical solution that use the utility model carry out
Improvement；Or it is not improved, the above-mentioned conception and technical scheme of the utility model are directly applied into other occasions, at this
Within the protection scope of utility model.
