Regeneration system capable of recycling steel casting sodium silicate waste sand

The utility model discloses a regeneration system capable of recycling steel casting sodium silicate waste sand. Firstly, sand blocks are subjected to graded crushing through the crushing device; thesand blocks are crushed into smaller particles; then, water glass impurities in the crushed sand are removed by the sand washing device; clean sand is conveyed into the drying and screening device; the sand-water mixture is dried through the drying machine, the dried sand is classified according to the volume size through the vibration screening machine, meanwhile, sewage discharged in the sand washing and drying process is subjected to decontamination treatment through the sewage treatment device, and clear water left after mud removal can be circulated into the sand washing device to be repeatedly used. And the device can completely remove water glass impurities in the casting mold waste sand, and enables the used sand to be recycled. 一种能够使钢铸造水玻璃废砂再利用的再生系统，首先通过破碎装置对砂块进行分级破碎，将砂块破碎成较小的颗粒，之后由洗砂装置去除破碎后砂子中的水玻璃杂质，并且将干
