Technical Field

The invention relates to the technical field of coking, in particular to a flap adjusting device in a small flue of a coke oven.

Background

The small flue of the coke oven is a channel of a regenerator connected with a waste gas shutter, cold air and cold coal gas enter when the air current rises, and hot waste gas is collected when the air current falls. Perforated grate bricks are often adopted at the top of the small flue, in order to ensure that the airflow distribution of the heat storage chamber is uniform, grate bricks with different resistances are required to be configured along the length direction of the heat storage chamber, and the perforated grate bricks are realized by prefabricating grate bricks with different apertures or changing the airflow channel area of an adjusting hole by utilizing an adjusting brick and a pull-out grate plate. In addition, a metal adjusting plate is arranged above the small flue to adjust the airflow of the regenerator.

When the adjusting bricks are used for adjustment, the lower part of each regenerative chamber is provided with a down-adjusting hole. And the grate plate is too long in adjusting stroke, so that even if the operation is performed from two sides, the maximum operating stroke can reach the half-position of the coke oven in the length direction, and the operation difficulty is higher.
