Background

At present, a dry slag removal system is mostly adopted in large and medium-sized thermal power plants to treat bottom slag of a coal-fired boiler, and the working process of the dry slag removal system is that hot slag discharged by the boiler falls onto a conveying belt of a dry conveyor after passing through a slag falling hopper and a pre-crushing hydraulic shutoff door and moves along with the conveying belt moving slowly. The slag is cooled in the dry conveyor, the cooled slag is conveyed by the conveyor belt to enter the crusher for crushing, and the crushed slag finally enters the intermediate slag bin or directly falls into the slag bin for storage. Slag silo bottom is equipped with the facility of unloading, a slag unloading to the transport vechicle in with the slag silo, however in the uninstallation transportation, often produce a large amount of raise dusts and cause the pollution to the surrounding environment, also caused the health threat to the staff, in the chinese patent document of application number CN201620935035.9, get rid of the raise dust through set up integrated cover on the scum pipe, however in the actual loading transportation, because the slag falls into speed very fast and the volume is big when loading, it is short and the raise dust scope is big to cause the raise dust time, it is relatively poor only to carry out dust removal effect through integrated cover, can not satisfy actual user demand.

The present application is made in view of this feature.
