The inside of the drying chamber is heated by the heating plate, the quartz sand is dried, and the treated quartz sand is discharged from the outlet hole 211.

[0075] The implementation principle of the quartz sand treatment equipment according to the embodiment is as follows: first, the quartz sand is poured into the screening box 123, and the screening box 123 filters the large-particle impurities in the quartz sand. Second, the quartz sand enters the containing groove 111, and the magnetic impurities in the quartz sand are adsorbed by the operation roller 132. The quartz sand is conveyed to the storage box 17 through the box body 11. Third, the suction mechanism 22 sucks the quartz sand into the oven 21 for drying treatment, and the dried quartz sand is discharged from the oven 21. If the magnetic impurities in the quartz sand are not removed cleanly, the quartz sand can be poured into the screening device 1 again for treatment, so as to further improve the quality of the quartz sand.
