Efficient drying device for quartz sand production

The utility model belongs to the field of quartz sand production, particularly relates to an efficient drying device for quartz sand production, and aims to solve the problems that the existing quartz sand is easy to cake, the quartz sand is difficult to scatter by turning over a drying roller, and the quartz sand needs to be manually collected after being dried. A drying barrel is rotatably mounted at the top of the heating base, a discharging head is fixedly mounted on one side of the drying barrel, an internal-tooth gear is fixedly mounted on the inner wall of the drying barrel, an internal-external-tooth gear is meshed with the inner side of the internal-tooth gear, and two connecting gears are meshed with the inner side of the internal-external-tooth gear. A supporting base is installed at the bottom of the heating base in a clamped mode, and two moving grooves are formed in the inner side of the supporting base. According to the quartz sand drying device, internal caked quartz sand can be scattered, the
