Abstract
Description
Technical Field
[0001] The present application relates to the technical field of coke ovens, and in particular to a coke oven chute dredging device. Background Art
[0002] As the coke oven ages, the inclined opening of the combustion chamber of the coke oven is often blocked by broken bricks or slag, making it difficult to expand the hole. If the hole is not expanded and cleaned in time, the passage of the heating gas will be blocked, resulting in insufficient heat supply in the combustion chamber and local coking, which seriously affects the quality of coke and even causes a difficult pushing accident.
[0003] The existing treatment method is to use φ14 or φ16mm round steel to make a foldable long steel chisel, which is inserted into the combustion chamber chute from the top of the coke oven through the fire hole, and the steel chisel is adjusted to poke the slag into the heat storage chamber or push away the broken bricks at the chute to achieve the purpose of hole expansion. Since the temperature of the combustion chamber can reach 1400℃, the existing long steel chisel is easily softened by heat. The existing coke oven chute dredging device can only remove the loose slag at the chute, but cannot remove the broken bricks or sintered slag that block part of the chute. Summary of the invention
