Civil engineering material lifting and separation treatment device

The utility model relates to a civil engineering material lifting and separation treatment device, which comprises a lifting cavity, wherein a rotating shaft is perpendicularly arranged in the lifting cavity; the upper end of the rotating shaft is connected with an upper driving motor on the upper part of the lifting cavity; a feed opening and a discharge opening are horizontally formed in the left side of the lower part and the right side of the top of the lifting cavity respectively; a separation cavity is formed below the discharge opening respectively; a fine residue cavity is formed in the lower part of the separation cavity; a filter plate is arranged between the separation cavity and the fine residue cavity; a lower driving motor is arranged at the middle position of the bottom of the fine residue cavity; a motor shaft is perpendicularly arranged on the upper part of the lower driving motor, and is connected with the middle position of the filter plate. According to the device, undesirable paper scrap can be conveniently separated from a civil engineering construction material after the civil engineering construction material is lifted, and undesirable fine residues can be conveniently separated, so that required solids can be used for civil engineering construction, the fine residues are used for other places, the civil engineering construction material is effectively and reasonably used, and civil engineering construction quality is improved.
