Dust falling device for quartz sand production

The utility model relates to the technical field of quartz sand production, and discloses a dust falling device for quartz sand production. The dust falling device for quartz sand production comprisesa crusher, a pipeline, an elevator, a magnetic separator, a classification screening system, a cloth bag, a vibrator, a screening machine, a feeding hopper and a dust falling device body, and the right side of the crusher communicates with the pipeline. The utility model discloses a dust falling device for quartz sand production. Operating by a fan, dust in the elevator is sucked out through thedust suction pipe; entering a water tank through a dust outlet pipe; the water adsorbs a part of dust into the water; secondary starting water pump, the water pump flows water into the rotary injectorhead through the water outlet pipe; due to the fact that the water pressure is adjusted to be large, the rotary spraying head sprays water mist, the water mist and the dust are adsorbed in the watertank, then the water mist fa
