The working principle of the invention is as follows: before use, water is injected into the cleaning barrel, and when the cleaning barrel is used, the driving motor is started and runs
Moving a crushing knife to operate, putting the plastic bottle into a crushing box, cutting the plastic bottle into small pieces of plastic by the crushing knife, enabling the plastic and liquid in the plastic bottle to flow into a cleaning barrel through a conveying pipe communicated with the crushing box, enabling the liquid to flow into a liquid collecting box from a notch in the process that the plastic and the liquid flow into the cleaning barrel, starting a propeller in a through pipe when the plastic falls into the cleaning barrel through the conveying pipe, enabling water in the cleaning barrel to transversely flow due to the fact that the through pipe is parallel to the bottom of the cleaning barrel when the propeller operates, enabling the water in the cleaning barrel to form a vortex after a period of time, enabling the plastic in the cleaning barrel to rotate along with the vortex, stopping the propeller after a period of time, stopping the water in the cleaning barrel from flowing, starting a lifting rod, supporting a screen plate to ascend when the lifting rod ascends, driving the plastic on the screen plate to ascend when the upper surface of the screen plate ascends to the, the lifting rod positioned at the lower end of the discharge hole stops lifting, the other lifting rod continues lifting to enable the screen plate to incline towards the discharge hole, and when the inclination angle of the screen plate is gradually increased, the plastic on the screen plate falls out of the discharge hole.
The plastic bottle cleaning machine has the beneficial effects that the plastic bottle is broken through the breaking knife, so that liquid in the plastic bottle flows out from the notch in the conveying pipe, the plastic bottle is separated from the liquid, water cannot be polluted by the liquid in the plastic bottle in the cleaning process, the cleaning beneficial effect is further influenced, the broken plastic bottle falls into the cleaning barrel, the plastic bottle is cleaned through vortex generated by the propeller, and the beneficial effect of simultaneously cleaning the inner wall and the outer wall of the plastic bottle is achieved.
Further, the bottom of the liquid collecting box is communicated with a liquid discharge pipe. Its purpose is convenient for discharge the liquid in the collection liquid case, avoids piling up flow out in the breach behind the excessive, flows to in the washing bucket.
Further, a filter screen is arranged at the water inlet of the through pipe. The purpose is to prevent plastic from entering the through pipe to block the propeller in the cleaning process.
Further, the bottom end of the cleaning barrel is communicated with a drain pipe, and a water stop valve is arranged on the drain pipe. The sewage cleaning device aims to discharge sewage which is cleaned for many times in the cleaning barrel through the sewage discharge pipe.
