Waste gas can be discharged, moreover it is possible to adjusting gas flow.During with BF gas heating ascending air, two exhaust gas discs are fallen by waste gas sectional wheel
Under, gas weight is lifted by coal gas sectional wheel, and air cover plate carries out, and coal gas and air are fed to regenerator.During down current just
Good on the contrary, gas weight is fallen, two exhaust gas discs lift, and air cover plate is closed, and tines is connected waste air with flue.
Traditional exchange shutter air door adjusting structure is that air door is a circular hole, by the door frame that leaks informaton, shape at circular hole
For square, air door circular hole is inscribed within, four square sides are fixed by four pieces of adjustable plates and covered, and it is by more that air, which feeds regulation,
The iron plate changed in exhaust gas disc air door frame square adjusts the size of air inlet, and polylith iron plate is flat to be ridden on air door frame, reach tune
Save the purpose of air door.Following defect be present in this air door adjusting structure：
（1）Because iron plate dimensions is identical, air door is adjusted aperture and controlled with iron plate area, exist sized span greatly and
The problem of degree of regulation is low；
（2）Iron plate is flat to be ridden on air door frame, is easily fallen into exhaust gas disc, sometimes jam coal gas, waste gas stone roller；（3）Wind is with the door open, burnt
Powder and booty are directly fallen into exhaust gas disc, are caused coal gas, waste gas stone roller to fall imprecision, are influenceed coke oven heating, cause coke quality
Decline with yield；
（4）Coke oven cokery side individual exhaust gas disc more than totally 100, due to the limitation of its structure and position, it is big to clean difficulty, cleaning works amount
Greatly.
The content of the invention
It is an object of the present invention to provide a kind of coke oven exchange shutter throttle opening adjusting means, it is possible to increase throttle opening
Degree of regulation, avoid particle granulated slag from falling into exhaust gas disc, solve problem present in background technology.
The technical scheme is that：
A kind of coke oven exchange shutter throttle opening adjusting means, comprising lower annulus base, upper regulation ring, regulation combined blade,
Indicator, valve position dial, moving vane and Air Filter, lower annulus base and upper regulation ring are the annulus to cooperate
Shape, upper regulation ring are located on lower annulus base, and upper regulation ring is provided with Air Filter, and lower annulus base is provided with valve position scale
Disk, upper regulation ring are provided with the indicator corresponding with valve position dial, are provided between upper regulation ring and lower annulus base
Combined blade is adjusted, the regulation combined blade is formed by stacking by multiple moving vanes.
The regulation combined blade is formed by stacking by eight moving vanes, and the moving vane is and upper regulation ring and lower circle
The arc-shaped structure that ring base is engaged.
The circumferencial direction of the upper regulation ring is provided with multiple regulation ring positioning holes, and moving vane is provided with to be determined with regulation ring
The upper steady pin that is engaged of position hole, the lower steady pin being engaged with lower annulus base is additionally provided with moving vane.
Upper steady pin and lower steady pin on the moving vane are located at the both ends of moving vane respectively.
The upper regulation ring is provided with hand driving lever, and indicator is fixed on hand driving lever.
Air Filter in the upper regulation ring is fixed on lower annulus base by dust-proof network framework.
Using the present invention, the regulation of exchange shutter throttle opening is realized by adjusting the circumferential displacement of combined blade
's.In use, lower annulus base is embedded in the air door circular hole of exhaust gas disc, during damper aperture, according to coke oven heating demand
Select suitable throttle opening, rotate clockwise hand driving lever, by indicator point to corresponding to scale on valve position dial,
Moved by the circumference of upper regulation ring, drive eight moving vanes in regulation combined blade that impartial displacement occurs, air door is justified
Hole diminishes, and reaches satisfied throttle opening.
The beneficial effects of the invention are as follows：The aperture of air door can be accurately controlled, simple to operate, degree of regulation is high, effectively
Prevent jam coal gas, the phenomenon of waste gas stone roller, made granular residue be not easy to fall into blast furnace gas pipeline and coke oven cokery side flue,
Exhaust gas disc scavenging amount is greatly reduced, ensure that the stable operation of coke oven heating system.
