Description

Technical Field

[0001] This application relates to the technical field of dry slag conveyors, specifically to a dry slag conveyor coke accumulation cleaning device. Background Art

[0002] After the adjustment of the coal blending method in the power plant, the melting point of the coke slag generated after boiler combustion has gradually decreased, which has made the phenomenon of coke slag accumulation (coke accumulation) at the dry slag conveyor more serious, and there is a tendency for the position of the coke accumulation to shift upward. Originally, the coke accumulation was mainly concentrated at the support crossbar at the bottom of the slag well, where there were usually slide rails and extrusion head crushing devices.

[0003] However, as the position of the coke accumulation moves upward, the existing extrusion head cannot reach the new coke accumulation position, so it cannot crush it and let it fall below, and thus cannot achieve the function of dredging the blockage. In addition, the existing extrusion head not only has a high installation cost, but also its installation position is fixed and cannot be adjusted according to actual needs during the later operation of the power plant. If new extrusion head equipment is added, additional guide rails need to be installed, which not only increases new areas prone to coke accumulation, but also increases the need for manual cleaning, thus introducing more potential safety hazards. Summary of the Invention
