The invention relates to a dust treatment device for a
belt conveyor. The dust treatment device comprises a feeding belt, a material collecting hopper, a sweeper, an atomizing pipeline, a spraying
nozzle, a
material flow adjustment device, a primary sliding groove, a secondary sliding groove, a feeding device, a material guide groove and a material receiving belt, wherein the feeding belt is connected with the material collecting hopper; the sweeper is mounted below the feeding belt; the atomizing pipeline and the spraying
nozzle are arranged at the periphery of the sweeper; the
material flow adjustment device is arranged in the material collecting hopper; the secondary sliding groove is formed below the sweeper; the lower end of the secondary sliding groove is connected with the primary sliding groove; the primary sliding groove is connected with the feeding device; the material guide groove is formed below the feeding device; the material receiving belt is arranged below the material guide groove. According to the dust treatment device for the
belt conveyor, the generation of dust is inhibited from the source, and the dust produced by the sweeper during a sweeping process can also be inhibited.
