<p>A belt drop point dust catching system for conveying bulk material by a belt comprises a closed hood (1) of a machine head, a material chute (2) and a lower closed hood (3) of a machine body. The discharge hole of the closed hood (1) of the machine head is connected with the feed hole of the material chute (2), and the discharge hole of the material chute (2) the feed hole of the lower closed hood (3) of the machine body. A first dust remover (4) is arranged at the top part of the lower closed hood (3) of the machine body, and a second dust remover (5) the closed hood (1) of the machine head. A dust gas return pipe (7) is arranged fixedly between the lower closed hood of the machine body and the material chute (2), its ports communicating respectively with the inner cavities of the material chute (2) and the lower closed hood (3) of the machine body. The system is easy to maintain and install, saving water resource, with ideal efficiency of dust removing, preventing secondary pollution.</p> |
