Description
Technical field
The utility model is related to waste heat boiler technical fields, and in particular to a kind of smoke wind pipe tertiary air tube shut-off device valve.
Background technology
On dry cement production line, tertiary-air pipe is the special smoke wind pipe by kiln head cover to dore furnace from grate-cooler,
High-temperature flue gas is provided for dore furnace fuel combustion to set up.And the distribution of tertiary-air pipe air quantity (such as distributes to cogeneration
System), the aperture of generally use slide valve controls；Slide valve realizes keying and the aperture control of flue, completes tunnel gas
With the adjusting and distribution of air quantity；Tertiary air tube shut-off device valve has very important effect on cement industry, it is also that adjustment is burnt
At the necessary means of workshop section.
And currently, the service life of tertiary air tube shut-off device valve is ideal not to the utmost, most of all at 6-10 months, some only has three
A month or so time, once slide valve damages, firing will be very passive, or even be difficult to continue.Some enterprises simply remove flashboard,
It is built a wall in air hose to substitute valve plate, but calcined by rotary kiln is the process of a dynamic change, just not when there is the fluctuation of kiln condition
The balance of rotary kiln and dore furnace wind can be adjusted, entire production and product quality are finally influenced.
Utility model content
The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and provide a kind of suitable for dry method water
Smoke wind pipe tertiary air tube shut-off device valve in the tertiary-air pipe and cogeneration high temperature smoke wind pipe of mud production line, it is above-mentioned to solve
Problem on deformation, the castable of large-scale gate valve plate fall off problem and service life problem.
Technical solution is used by realize the purpose of this utility model：
A kind of smoke wind pipe tertiary air tube shut-off device valve, including valve plate and the combination anchor that is connect with the valve plate, institute
It includes the cast wearing layer that valve plate substrate and high alumina ceramic material are formed to state valve plate, and the cast wearing layer forms the valve plate
On windward side, it is fixed with latticed heating muscle on the valve plate substrate on two sides, in the grid of the latticed heating muscle
It is provided with and eliminates stress hole.
The combination anchor includes the U-shaped anchoring piece being welded on flashboard substrate and Ω type round steel, the U-shaped anchoring
Part and the Ω types round steel right-angled intersection, are welded with valve plate substrate respectively.
The U-shaped anchoring piece surface is coated with bitumen layer, and the both ends of the U-shaped anchoring piece are equipped with plastic cap.
The valve plate of the utility model slide valve is unlikely to deform, castable is not easily to fall off and valve plate high temperature resistant, resistance to erosion, tool
There is long service life.
Description of the drawings
Fig. 1 is the structural schematic diagram of smoke wind pipe tertiary air tube shut-off device valve；
Fig. 2 is the structural schematic diagram of the substrate of valve plate.
Specific implementation mode
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Shown in Fig. 1-2, a kind of smoke wind pipe tertiary air tube shut-off device valve, including：
Valve plate 1 and the combination anchor being fixedly connected with the valve plate, the valve plate include valve plate substrate 11 and height
The cast wearing layer 4 that aluminum porcelain is formed, the cast wearing layer is formed on the windward side of the valve plate, on the valve plate substrate
It is fixed with latticed heating muscle 13 on two sides, is provided in the grid of the latticed heating muscle and eliminates stress hole 12.
The elimination stress hole is round hole, and diameter is determined according to the size of valve plate, not influence the intensity of valve plate
It is limited, one or two can be opened in each grid, according to the size in hole come quantification.By on flashboard
Windward side, as castable, forms pouring layer using alumina porcelain, ensures slide valve in high temperature and the higher evil of dust hardness in this way
Bad operating mode is small indeformable and wear-resisting, can normal operation, increase valve service life to 1 year or more.
Stress hole is eliminated by offering, i.e., opens some circular holes, such as Fig. 2 on flashboard substrate, it is therefore an objective to is heated in flashboard
Reduce stress concentration when expansion, flashboard substrate is made of high-temperature heat-resistance Steel material；Grid is arranged on flashboard substrate simultaneously to add
Strengthening tendons, both measures greatly reduce flashboard and are deformed under high temperature environment.
Therein, the combination anchor includes that the circular steel being welded on flashboard substrate makes the U-shaped anchoring piece to be formed
1, the welding ends of U-shaped anchoring piece is straight line portion, can increase the fusion length with valve plate substrate, while in U-shaped anchoring piece bottom
Covering Ω type round steel part 3 simultaneously welds, and the U-shaped anchoring piece and the Ω types round steel part right-angled intersection are welded with valve plate substrate respectively
It connects, plays the role of double insurance, U-shaped anchoring piece ensures to thermally expand system using the heat-resisting steel material as flashboard substrate
Number is consistent, and such combination anchor is very secured, will not fall off substantially, would not also cause the de- of castable in production process
It falls.
Bitumen layer must be formed, while U-shaped in the surface smear pitch of U-shaped anchoring piece before carrying out castable construction
Plastic cap 2 is installed on anchoring piece top, as shown in Figure 1, smearing pitch and top installation plastic cap are provided on U-shaped anchoring piece
Flashboard valve eliminates the heat expansion stress between U-shaped anchoring piece and castable under worst hot case, in order to avoid castable is caused to split
Seam.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
