When the air flow is lowered, the gas mounds fall down, the two waste gas trays are lifted, the air cover plate is closed, and the two fork parts are communicated with the flue to discharge waste gas.
The traditional switching shutter air door adjusting structure is characterized in that an air inlet is a round hole, an air discharging door frame is arranged at the round hole, the shape of the air discharging door frame is square, the air discharging door frame is internally tangent to the air door round hole, four sides of the square are fixedly covered by four adjusting plates, the air supply adjusting mode is to adjust the size of an air inlet by changing an iron plate in the square of an air door frame of an exhaust gas disc, and a plurality of iron plates are horizontally lapped on the air door frame to achieve the purpose of adjusting the air door. Such damper adjustment structure has the following drawbacks:
(1) Because the iron plates have the same size and specification, the air door adjusting opening is controlled by the iron plate area, and the problems of large adjusting size span and low adjusting precision exist;
(2) The iron plate is horizontally lapped on the air door frame, is extremely easy to fall into the waste gas tray, and sometimes blocks gas and waste gas mounds; (3) When the air valve is opened, coke powder and dirty matters directly fall into the waste gas tray, so that coal gas and waste gas mounds fall inaccurately, the heating of the coke oven is affected, and the quality and yield of coke are reduced;
(4) The coke side of the coke oven has more than 100 waste gas discs, and the cleaning difficulty and the cleaning workload are high due to the limitation of the structure and the position of the waste gas discs.

The dustproof net on the upper adjusting ring is fixed on the lower circular ring base through a dustproof net framework.
By adopting the invention, the opening degree adjustment of the air door of the exchange shutter is realized by adjusting the circumferential displacement of the combined blade. When the air door is opened, the proper air door opening is selected according to the heat supply requirement of the coke oven, the manual lever is rotated clockwise, the indication needle points to the corresponding opening to display scales on the dial, and eight movable blades in the adjusting combined blade are driven to generate equal displacement through the circumferential movement of the upper adjusting ring, so that the air door opening is reduced, and the satisfactory air door opening is achieved.
The beneficial effects of the invention are as follows: the opening degree of the air door can be accurately controlled, the operation is simple, the adjusting precision is high, the phenomena of blocking gas and waste gas mounds are effectively avoided, particle residues are not easy to fall into a blast furnace gas pipeline and a coke side flue of the coke oven machine, the cleaning amount of a waste gas disc is greatly reduced, and the stable operation of a heating system of the coke oven is ensured.
