Description

Technical Field

[0001] The utility model relates to the technical field of transfer equipment, in particular to a sealed conveying and storage system for roasting powder. Background Art

[0002] After the sintering material is crushed in the furnace, it is transported to the belt conveyor through the electric shock discharging machine, and then transported to the drum screening machine for screening. The screened material (large block material) is transported to the roasting block material bin through the belt conveyor. The screened material (fine powder material) is transported to the raw material batching bin of the block making system through the belt conveyor. The fly ash generated by drying, roasting, smelting, and ring bag dust collector in the factory area is collected in the fly ash bin and then transferred to the block making batching bin (or aging area batching).

[0003] However, the existing roasting powder is transported through an open belt conveyor. During the transportation process, because the powder does not contain moisture and the belt conveyor equipment is not sealed, a lot of dust is generated, causing secondary pollution, posing an environmental hazard and affecting the environmental management within the factory.
