Energy-saving and environment-friendly screening device for waste recycled concrete

The invention relates to the technical field of recycled concrete, in particular to an energy-saving and environment-friendly waste recycled concrete screening device which comprises a rack, a screening barrel is rotatably mounted on the rack through a rotating shaft, a first through hole is formed in the side wall of the screening barrel, and a synchronous barrel is rotatably connected to the rack; the synchronous barrel is arranged on the outer side of the screening barrel in a sleeving mode, and second through holes in one-to-one correspondence with the first through holes are formed in the side wall of the synchronous barrel. The diameter of the screening barrel is smaller than that of the synchronous barrel, the screening barrel and the synchronous barrel are eccentrically arranged, a screening area is formed on one side of the screening barrel, the lower portion of the side, located in the screening area, of the screening barrel is attached to the inner wall of the synchronous barrel, and first through
