Technical Field

the invention relates to the technical field of sealing devices of belt conveyors, in particular to a double-layer sealing type belt conveyor.

Background

the belt conveyor is often used in bulk powder material conveying, during the conveying process, materials on the existing belt conveyor are exposed in the air, dust or other impurities in the production environment can enter the materials, the materials are polluted, the performance of the materials is affected, and even scrapping treatment is carried out; meanwhile, the powdery material on the belt conveyor can be scattered in the production environment in the conveying process, so that the production environment is influenced.

When the powdery material is transported by the transporter, the diffused material dust can not only influence the workshop environment, but also waste the part of the material, thereby causing resource waste.
