[0040] In this embodiment, a device for efficiently recycling concrete waste using activated water is provided.

The conveying pipe 14 is connected to the external activated water supply equipment. , activated water can be transported through the delivery pipe 14, and the activated water is sprayed through the equidistantly arranged nozzles 15 to regenerate the concrete particles in the waste. When the waste is mixed, the electric telescopic rod 21 is started to drive the fixed frame 22 to move upward, and the fixed frame 22 drives the sliding rod 19 to move upward. Then the sliding rod 19 drives the baffle 16 to open, and the mixed waste will fall onto the discharge channel 24 through the gap between the two baffles 16, and slide to one side through the discharge channel 24. The discharge flow rate can be controlled by controlling the size of the gap between the baffles 16.
