Color sorting device for quartz sand purification

The utility model discloses a color sorting device for quartz sand purification, which comprises a box body, an impurity box and a quartz sand loading box are respectively arranged on two sides of a base, baffles are arranged on the outer sides of the impurity box and the quartz sand loading box, a first CCD (Charge Coupled Device) sensor is arranged on the right side of a first inclined plate, and a second CCD sensor is arranged on the right side of a second inclined plate. A second CCD sensor is fixedly connected to the lower side of the fixing piece, and a collecting box is arranged on the lower side of the first CCD sensor. According to the structure, the electric push rod drives the baffle to move upwards, so that quartz sand and impurities which are separated by color sorting in the device can be prevented from falling to the outer side, the falling quartz sand and the impurities which do not meet the requirement cannot fall out of the outer side, and after the first CCD sensor performs color sorting on
