The utility model discloses a lime powder screening device for calcium carbide production, which relates to the technical field of lime powder screening and comprises an external screening box, a second through groove is formed in the top of the external screening box, a storage box is arranged in the external screening box, and an air exhaust box is fixedly mounted on one side of the external screening box. The device has the advantages that the reciprocating lead screw is driven by the second motor to rotate, the moving plate on the outer side can be driven by rotation of the reciprocating lead screw to move, and when the moving plate moves, the piston is driven to slide in the air exhaust box; therefore, lime powder in the air can be sucked in through the first pipeline on one side of the second pipeline and then sprayed into the filter box through the third pipeline, the lime powder in the air can be filtered through the filter screen, finally the air is sprayed out through the air outlet, purification wo
