The invention belongs to the technical field of environment protection, and particularly discloses dust treatment equipment. The dust treatment equipment comprises a machine frame; a material storagecylinder and a collecting cylinder are arranged on the machine frame; the material storage cylinder communicates with a material outlet pipe; a rotating shaft is arranged on the outer side of the material outlet pipe; the rotating shaft is fixedly connected with a soft shaft; one end of the soft shaft extends into the material outlet pipe; a dredging switch and an impeller are arranged in the collecting cylinder; the machine frame is also fixed with an annular groove and an inner gear ring; the tooth shape of the inner ring gear is conical; a bevel gear is arranged in a gear hole of the innergear ring; the bevel gear is rotatably connected with the machine frame; a gear shaft is arranged between the inner ring gear and the bevel gear; the lower end of the gear shaft is fixedly connected with a compressing rod; a spring is arranged in the annular groove; the inner end of the spring is fixedly connected with an eccentric position of the upper end surface of the bevel gear; the inner endof the spring is fixedly connected with a first magnet; a second magnet is fixedly arranged on the inner wall of the annular groove; the outer circle of the rotating shaft is fixedly connected with aconnecting rod; and the connecting rod is fixedly connected with the outer end of the spring. By adopting the dust treatment equipment, the phenomenon that dust accumulates at the material outlet pipe can be avoided, so that the dust flows more smoothly.
