At this time, the formation switch of the cleaning and dehydration position S1 is triggered. Under the action of the water pump 401, the water in the water storage tank 400 enters the stirring sleeve 211 along the water supply inner pipe 402 and the water supply outer sleeve 403, flows along the mixing side pipe 216, and is finally discharged from the jet hole 217. The sprayed water column can quickly rinse the bottle pieces. Subsequently, the water pump 401 stops working and stops supplying water. Driven by the scraper inclined plate 218, the water in the water storage tank 400 flows into the stirring sleeve 211. The bottle pieces rotate at high speed to achieve centrifugal dehydration. The heat sealing unit 206 provides hot air, which enters the rotating air guide pipe 207 along the hot air buffer box 204, and then enters the mixing side pipe 216 along the stirring sleeve 211, and then is ejected along the jet hole 217. The ejected hot air can assist in the dehydration of the bottle pieces, completing the integrated design of cleaning and dehydration. When the wear-resistant ring 405 is in the unloading position S2, the first piston column 212 and the second piston column 215 are in the lowest position, that is, the position of the discharge notch 214. At this time, the bottle pieces will be thrown into the collecting box 105 to complete the unloading; During the whole processing process, the stirring sleeve 211 rotates to drive the toggle crossbar 210 and the pre-treatment brush 209 to rotate, so as to brush the bottle flakes. In addition, driven by the pusher, the toggle crossbar 210 and the pre-treatment brush 209 can also float up and down, thereby further improving the stirring and brushing effects. The wastewater generated by cleaning enters the wastewater collection tank 104, and then enters the purification component 300. After the water is discharged along the recovery pipe 308 and enters the purification box 301, the reaction force generated by the water discharge of multiple rotating drainage pipes 302 constructs a rotational torque, thereby causing the rotating drum 305 to rotate. The rotating arc plate 307 can guide the water power discharged from the recovery pipe 308, thereby assisting the rotation of the rotating drum 305. The inner wall of the purification box 301 is provided with a scraper side plate 311 that matches the outer wall of the filter mesh surface 304. When the rotating drum 305 rotates, the scraper side plate 311 will remove impurities accumulated on the filter surface of the filter mesh surface 304, thereby avoiding the problem of clogging. The rotational power here comes from the energy contained in the water itself, without the need for additional power, which has an energy-saving effect.
