Abstract
A kind of Aerated sealed slide gas baffle door, including connecting rod A and connecting rod B, described connecting rod A drives multi-disc odd-numbered blade to rotate, connecting rod B drives multi-disc even leaves to rotate, inflatable seal device is provided between odd-numbered blade and even leaves, inflatable seal device includes the telescopic shaft being arranged on even leaves, the cavity for being disposed on one end open in odd-numbered blade coordinated with telescopic shaft, annular air-pocket is provided with cavity, annular air-pocket is connected with inflator pump.The utility model has the advantages that：With inflated airbag, separate caused gap between script odd-numbered blade and even leaves, strengthen sealing function, energy-conserving and environment-protective.
Description
Technical field
The utility model belongs to smoke sealing device field, and in particular to a kind of Aerated sealed slide gas baffle door.
Background technology
It is right in the industry that heating power heating etc. can produce a large amount of flue gases with continuous improvement of the country to environmental requirement
Fume emission index there has also been higher requirement.Therefore, on the links from boiler combustion to fume emission to air all
Need accordingly to improve professional technique.Generally, gas baffle door is equiped with the flue of steam generator system, turning off, opening, shunting
With regulation flue flue gas, wherein, if contain more harmful components in flue gas, for sealing system sealing property require
Can be more strict.
Sealing between the sealing of gas baffle door mainly blade between blade and frame inner wall.All it is originally to rely on
Set flexure strip and doorframe inner ring that diaphragm seal is set in blade surrounding, when blade is closed, flexure strip and flexure strip and flexure strip
Formed and be in close contact between diaphragm seal, be so achieved that sealing.But because the size of blade is very big, flexure strip and elasticity
There are some gaps between piece and flexure strip and diaphragm seal unavoidably, this just have impact on sealing property.
Access is dried among some other gas baffle doors, clean hot-air can block flue gas by but blowing hot-air
Device to be always maintained at normal power-up during operation, cause human and material resources and energy waste.
The content of the invention
For deficiency of the prior art, the utility model provides a kind of Aerated sealed slide gas baffle door, existing to solve
There is the problem of gas baffle door energy resource consumption in technology is big, sealing effectiveness difference.
The utility model is achieved through the following technical solutions.
A kind of Aerated sealed slide gas baffle door, including connecting rod A and connecting rod B, described connecting rod A drive multi-disc odd-numbered blade
Rotate, connecting rod B drives multi-disc even leaves to rotate, and inflatable seal dress is provided between described odd-numbered blade and even leaves
Put, described inflatable seal device includes being arranged at telescopic shaft on even leaves, and what is coordinated with described telescopic shaft is to set
The cavity of one end open in odd-numbered blade is placed in, annular air-pocket is provided with described cavity, described annular air-pocket is connected with
Inflator pump.The sealing effectiveness of air inflation sealing device is than some hard contact good sealing effects, and aeration speed is fast, simple in construction, section
Can environmental protection.
Preferably, described telescopic shaft is controlled by minitype cylinder, the recessed of annular is offered on described telescopic shaft
Groove, described groove are used to accommodate annular air-pocket.The groove of annular is used to accommodate the air bag full of gas, good sealing effect.
Preferably, the flexible pad of the end set of described cavity.Cushion prevents for a long time using abrasion is produced, firmly
Contact of the material with soft material make it that gap is more small.
Preferably, described inflator pump is arranged at the side of no flue gas.Smoke pollution is prevented, is filled with to air bag,
If air bag is damaged, will leak.
Compared with prior art：With inflated airbag, separate caused gap between script odd-numbered blade and even leaves,
Strengthen sealing function, energy-conserving and environment-protective.

Fig. 3 is the structural representation that odd-numbered blade of the present utility model and even leaves coordinate.
Fig. 4 is the structural representation of even leaves of the present utility model.
Fig. 5 is the structural representation of odd-numbered blade of the present utility model.
Fig. 6 is the enlarged drawing at Fig. 5 A in the utility model.
Embodiment
Below in conjunction with the accompanying drawings with embodiment, the utility model is described further.
Aerated sealed slide gas baffle door, including connecting rod A1 and connecting rod B2, described connecting rod A1 drive multi-disc odd-numbered blade
11 rotate, and connecting rod B2 drives multi-disc even leaves 21 to rotate, and is provided with and fills between described odd-numbered blade 11 and even leaves 21
Gas formula sealing device, described inflatable seal device include the telescopic shaft 31 being arranged on even leaves 21, stretched with described
The cavity 4 for being disposed on one end open in odd-numbered blade 11 that contracting axle 31 coordinates, annular air-pocket is provided with described cavity 4
32, described annular air-pocket 32 is connected with inflator pump 33, is provided with slideway 4 on described even leaves 21, on described slideway 4
Slide bar 41 is provided with, the end set of described slide bar 41 has block, and described block is used for being arranged at odd-numbered blade 11
Plugging block 42 coordinate, described telescopic shaft 31 is controlled by minitype cylinder, offered on described telescopic shaft 31 annular
Groove, described groove are used to accommodate annular air-pocket 32, the flexible pad 43 of end set of described cavity 4, described inflation
Pump 33 is arranged at the side of no flue gas.
In use, when connecting rod A1 and connecting rod B2 are rotated backward, odd-numbered blade 11 and even leaves 21 mutually close
Hold together, after closing up in place, minitype cylinder starts, and telescopic shaft 31 extends, and telescopic shaft 31 stretches to one end open in odd-numbered blade 11
Cavity 4 in, after telescopic shaft 31 all stretches out, inflator pump 33 works, and is inflated into annular air-pocket 32, and annular air-pocket 32 is full of
After gas, it is stuck in the annular groove on telescopic shaft 31, the gap between odd-numbered blade 11 and even leaves 21 is blocked, and plays height
Imitate the effect of sealing.
If flue gas is still entered by gap, slide bar 41 is when connecting rod A1 and connecting rod B2 is reversely rotated in place, slide bar 41
Moved in slideway 4, slide bar 41 moves from left to right, stops when reaching the position of limit switch on the right, the end of slide bar 41
Block withstand plugging block 42, secondary seal is formed in closed space.
The scope of protection of the utility model includes but is not limited to embodiment of above, and the scope of protection of the utility model is to weigh
Sharp claim is defined, and any replacement being readily apparent that to those skilled in the art that this technology is made, deformation, improvement are each fallen within
The scope of protection of the utility model.
