The impact plate 713 blocks the water flow, causing the water to impact the inside of the spiral screen drum 71 to flush the waste. At the same time, the spiral plate 711 fixed in the spiral screen drum 71 plays a role of horizontally conveying the waste as the spiral screen drum 71 rotates. The waste can be flushed and conveyed horizontally at the same time, so that the bottle cap waste can be continuously cleaned. The flushed water is The bottom of the cleaning pipe 6 is discharged through the return pipe 62, and the cleaned waste enters the drying pipe 7 through the connecting pipe.
