When the chain runs, the roller rotates synchronously, and the front end of the slag shovel plate always adheres to the chain, enabling the slag shovel plate to completely remove the furnace slag adhered to the chain, effectively solving the existing technical problems and ensuring the normal operation of the equipment.

Description

Technical Field

[0001] The present invention relates to a slag conveyor for a waste incineration power plant, and in particular to a slag shoveling device for a slag conveyor of a waste incineration power plant. Background Art

[0002] At present, the wet scraper conveyor of the slag conveyor in a waste incineration power plant is composed of a sprocket, a tail wheel, a chain, a housing, a track, a speed reducer, a motor, bearings and other structures. When the double-row chain slag conveyor operates, the chain meshes with the sprocket. When there are sundries or relatively large pieces of slag and other sundries on the chain, these sundries and slag will adhere to the sprocket. When the chain and the sprocket mesh again, since there are sundries stuck inside the sprocket, this will cause a gap when the chain and the sprocket mesh. When the meshing gaps of the two sides of the chain and the sprocket are different, accidents such as chain tooth skipping and helical teeth will occur. In severe cases, the chain of the chain type speed reducer at the sprocket will be broken, which has an adverse impact on the normal operation of the on-site equipment. Summary of the Invention
