A sand-filtering device for filtering sands produced by a sandblast machine that includes a housing, a supporting plate, at least one filtering sleeve, a division module and an air pump. The housing is connected to the sandblast machine to receive the sands. The supporting plate is detachably mounted in the housing. The filtering sleeve is hung on the supporting plate. The division module is detachably mounted in the housing. The division module has at least one passage connected to the filtering sleeve. The air pump pumps the sands through the passage into the filtering sleeve so that the sands are filtered by the filtering sleeve. To replace the filtering sleeve, the supporting plate and the division module are detached from the housing and directly thrown away together with the filtering sleeve. That is fast, efficient and safe.
