4. increase adjusting mechanism of the present invention in combustion furnace, it is ensured that burner hearth and pipeline are not subjected to displacement, and production process is steady
It is fixed.
The detailed technology scheme of the present invention is further described below in conjunction with the drawings and specific embodiments.
Brief description of the drawings
Fig. 1 is the structure diagram of burner hearth high-temp waste gas conveyance conduit anticracking break structure described in embodiment.
Embodiment
Embodiment
As shown in Figure 1, there is provided a kind of burner hearth high-temp waste gas conveyance conduit anticracking break structure, it includes waste gas pipeline road
1, because waste gas pipeline road is generally longer, therefore it need to be connected by the equal pipeline of more diameters, in the connection of pipeline and pipeline
Place sets the adjusting mechanism that thermal expansion telescopic adjustment function can be provided for waste gas pipeline road.
Adjusting mechanism provides for traditional pipeline and pipeline weld stablizes flexible effect, it is well known that pipeline by
Heat is cooled and can be deformed, and the high temperature SO that the gas of the burner hearth of the present embodiment discharge is 800 DEG C2Gas, it passes through exhaust gas
During conveyance conduit, weld will be split or be directly broken the risk of distortion of disengaging, and the in due course introducing of adjusting mechanism
Enough extendable rooms can be effectively provided for weld.
Specifically, adjusting mechanism includes sealed set in pipeline and the ring drum face structure 21 of pipeline junction, ring drums
Structure 21 periphery in face protrudes from pipeline periphery and is uniformly arranged on pipeline periphery, it includes being sent into the seal for pipe joints at end with exhaust gas and connects
The first cydariform face 211 for connecing, send out with exhaust gas the second cydariform face 212 that the seal for pipe joints at end is connected, arranged on the first cydariform face and
Cylindrical extended surface 213 between second cydariform face, the first cydariform face, the second cydariform face and cylindrical extended surface form annular
The inner groovy 214 of drum face structure.
In the present embodiment, the diameter of annular drum face structure 21(The body diameter of i.e. cylindrical extended surface)For pipe diameter
1.5 again.
The width size of cylindrical extended surface 213 directly determines the telescopic space between pipeline and pipeline, this implementation
The cylindrical extended surface width of example is 20mm, you can the shrink space of 20mm is provided for pipeline generating surface.
In addition the first cydariform face 211 and the second cydariform face 212 should have under sustainable annular drum face structure itself normality not
The thickness of macroscopic deformation occurs, the present embodiment selects the metal material of 5mm thickness to make.
Wherein annular drum face structure 21 is welded to connect with pipeline, and the cylindrical extended surface 213, first of annular drum face structure rouses
211 and second cydariform face 212 of shape face is integrally formed.
Further to strengthen telescopic adjustment effect, the adjusting mechanism of the present embodiment is further included in waste gas pipeline road 1
Exhaust gas diversion division 22, the periphery of 22 one end of exhaust gas diversion division connects in the seal for pipe joints that end is sent into along exhaust gas conveying direction and exhaust gas
Connect, and the other end extends to exhaust gas and sends out in the pipeline at end, the sealed connection mode of exhaust gas diversion division and pipeline in the present embodiment
For welding.
Exhaust gas diversion division 22 is sealing fixing end equivalent to one end in waste gas pipeline road, and the other end is free end, high
Warm air directly will be admitted to latter pipe when by the adjusting mechanism part in waste gas pipeline road 1 by exhaust gas diversion division 22
In road, almost only a small part can be back to annular drum face structure 21 to high temperature gas flow in the free end of exhaust gas diversion division 22,
So exhaust gas diversion division then prevents most of gas shock annular drum face structure 21.
Telescopic variation can also occur for exhaust gas diversion division 22 itself to adapt to the impact of high temperature gas flow at the same time.
The present invention structure be not limited to above-mentioned concrete mode and structure setting, as long as with structure of the present invention
The technical solution of close or similar set-up mode is within the scope of the present invention.
