The utility model discloses a
sand blasting dust separation device, a feeding hole of the
sand blasting dust separation device is connected with
sand blasting equipment, and the sand blasting dust separation device comprises a separated sand flowing groove and a separator, a feeding port of the separating type
quicksand groove is communicated with sand blasting equipment, the separating type
quicksand groove can separate sundries, a discharging port of the separating type
quicksand groove is communicated with a feeding port of the separator, the separator is arranged below the separating type quicksand groove, and dust of
grinding materials is separated through the separator and can be collected. According to the sand blasting dust separation device,
mixed waste materials are separated through the arrangement of the separation type sand flowing groove, and waste caused by the fact that the
abrasive materials which can be used are mixed into waste
abrasive materials is avoided. And negative-pressure separation is carried out through the negative-pressure separation area in the separator, so that the quality of the recycled
grinding materials is guaranteed, and
dust pollution is avoided. And moreover, the separator can adjust, adsorb and separate abrasives with different specific gravities according to the characteristic that different abrasives have different specific gravities, so that the applicability of the sand blasting dust separation device is improved.
