Description
Technical field
The present invention relates to roaster technical field, more particularly to it is a kind of be used in calcining kiln flue, favorable sealing property
A kind of calcining kiln flue door.
Background technology
Roaster is a kind of device that sulphide ore is calcined with fluidization of solid technology.Roasting process has reaction heat releasing, production
The raw gas containing sulfur dioxide is mainly used to manufacture sulfuric acid, and slag is then used as metallurgical raw material.Contain in roaster discharge waste gas
SO 2 tail gas, a large amount of discard are discharged into air, easily cause air pollution, meanwhile, the discharge of sulfurous gas easily forms acid
Rain, serious pollution is caused to atmosphere, therefore, generally use flue gas desulfurization unit to the sulfurous gas in flue at
Reason.
But once the flue gas desulfurization unit breaks down, maintenance down is just needed, it is necessary to close during maintenance
Close to desulfurization unit ventilate main channel, it is therefore desirable to open up a bypass and continue to be vented, prevent flue gas can not drain and
Cause furnace pressure to increase, and bypass and use limestone-gypsum wet flue gas desulfurization technology, it is therefore desirable in main channel and bypass
It is upper to set baffle door to switch venting channels.During flue gas desulfurization unit normal work, by-pass damper is closed, and main channel baffle plate is opened
Opening, flue gas is outer again after main channel enters flue gas desulfurization unit progress desulfurization process to be arranged, and in flue gas desulfurization unit failure, it is other
Road baffle plate is opened, main channel flapper closure, and flue gas is arranged from bypass is outer, and therefore, in the case of normal work, bypass necessarily be in
Closed state, to prevent sulfurous gas from leaking, therefore the sealing property of baffle plate is particularly important.
Chinese patent CN201476036U discloses the blinds gear on a kind of board gate of flue gas desulfurization, including valve body, valve body
Plate, a pneumatic means are arranged on the lower end of valve body, and valve shaft is connected on valve body, and blinds baffle plate is connected on valve shaft, each valve
Axle is connected by connecting rod, crank with pneumatic means, and the pneumatic means of valve body lower portion is connected with some valve shafts in bottom, support catch,
Sealing shell fragment is connected in blinds baffle plate.Technical scheme disclosed by the invention passes through the support catch in blinds baffle plate and sealing shell fragment
To ensure sealing, it is no longer necessary to high-temperature gas is passed through into blinds baffle plate to ensure sealing property, reduces gas baffle
Operating cost, but in the technical scheme of the disclosure of the invention, blinds baffle plate deformable blade, can reduce after a period of time is run
Sealing property, and easily there is blade bite phenomenon.
And for example, Chinese patent CN104771997A discloses a kind of bypass with sealing device for sintering flue gas desulfurization
Baffle door, including valve body, plate, door body framework and the telescopic system for driving plate vertically to move reciprocatingly；Institute
It is a framework surrounded by upper ledge, lower frame, left frame and right frame to state valve body, and valve body is fixed on door body framework, and one end enters for flue gas
Mouthful, the other end is exhanst gas outlet, and valve body is provided with chute, and the plate is arranged at smoke inlet to the path of exhanst gas outlet,
Plate size is more than the size of smoke inlet, and plate surrounding is located in chute, and a circle deformation is formed between plate surrounding and valve body
Space；Smoke inlet is connected with exhanst gas outlet by deforming space；Also include be arranged at valve body be used for block deform space with
Separate smoke inlet to the sealing device of exhanst gas outlet path；The upper ledge of the valve body holds plate provided with what is be adapted to plate
The hole passed through, the telescopic system are arranged at the top of door body framework.Technical scheme disclosed by the invention, is slided using plate
The design that is arranged in valve body is, it is necessary to when closing by-pass damper door, in plate insertion valve body, it is necessary to when opening by-pass damper door,
Plate detaches valve body, and deformation space is surrounded between plate surrounding and valve body, therefore, when plate inserts or detaches valve body, no
Bite phenomenon occurs, and the sealing problem between louvre blade is not present in plate compared with louvre blade, it is only necessary to become in closure
Shape space can realizes sealing function, therefore seals conveniently, and sealing property is more preferable, it is ensured that by-pass damper door 100% seals,
But the technical scheme of the disclosure of the invention needs to take larger space.

2121, as shown in figure 5, right angle sheet of the support catch 2121 into bending, support catch 2121 flushes with elastic sealing strip 212,
Set support catch 2121 to press elastic sealing strip 212 located at the adjacent wall of two impeller 21, prevent elastic sealing strip 212 from sticking up
Rise, to improve sealing property.
As shown in figure 3, the 3rd sealing mechanism is including scalable close in the both sides side frame body of door body frame 1 (103,104)
Block block 213, door body frame 1 is connected with two pieces of telescopic sealing blocks 213 per side, and is located at the both sides of blinds baffle plate 2 respectively.It can stretch
Contracting sealing block 213 is connected with telescopic system, is driven and stretched by telescopic system, when telescopic system drives telescopic sealing block
During 213 contraction, telescopic sealing block 213 is closed in the both sides side frame body of door body frame 1 (103,104), when telescopic system driving can
When the flexible stretching of sealing block 213 tells that door body frame 1 is outer, telescopic sealing block 213 partly overlaps with blinds baffle plate 2.
As shown in figure 3, be used as preferably, in a preferred embodiment of the invention, telescopic sealing block 213 and blinds
It is provided with seal between baffle plate 2 to fill, the structure of its seal is：Airbag chamber is equipped with each telescopic sealing block 213
2131, airbag chamber 2131 is interior to be provided with air bag 2132, and air bag 2132 is set along the short transverse of door body frame 1, and the pressure of air bag 2132 is located at hundred
The both sides two sides of leaf baffle plate 2, as it is further preferred that in a preferred embodiment of the invention, the cross section of air bag 2132 into
" convex " shape, the wide portion of " convex " shape air bag 2132 are embedded in airbag chamber 2131, and " convex " shape air bag 2132 connects inflation mechanism 2133,
When blinds baffle plate 2 rotates, inflation mechanism 2133 is non-aerating, and telescopic sealing block 213 is closed in door body frame 1, works as blinds
When baffle plate 2 closes, telescopic sealing block 213 is stretched out, and inflation mechanism 2133 is inflated into " convex " shape air bag 2132, " convex " shape
The narrow portion pressure of air bag 2132 is located at the both sides of blinds baffle plate 2, is not only exerted a force to the two side walls of blinds baffle plate 2, prevents blinds baffle plate 2 from returning
Turn, avoid blinds baffle plate 2 from deforming, while realize the left and right sides of blinds baffle plate 2 and the sealing function of door body frame 1.
The preferred embodiments of the present invention have shown and described in described above, as before, it should be understood that the present invention is not limited to
Form disclosed herein, the exclusion to other embodiment is not to be taken as, and can be used for various other combinations, modification and ring
Border, and can be modified in this paper invented the scope of the idea by the technology or knowledge of above-mentioned teaching or association area.And this
The change and change that field personnel are carried out do not depart from the spirit and scope of the present invention, then all should be in appended claims of the present invention
Protection domain in.
