[0030] When the polyethylene waste recycling and granulation equipment is used, the rotating net cylinder is first raised to the highest point by the multi-section lifting rod, so that the feed connection port corresponds to the feed pipe, and then the polyethylene waste is added to the feed hopper and enters the rotating net cylinder from the feed pipe. Then the multi-section lifting rod is retracted and descended, and half of the rotating net cylinder is immersed in the cleaning liquid in the cleaning box. The driving motor is started to drive the rotating net cylinder to rotate, and the polyethylene waste in the rotating net cylinder is fully cleaned. After the cleaning is completed, the multi-section lifting rod is raised to half the height, and the rotating net cylinder is controlled to stay at the height of the shower pipe. The shower pipe is used to wash the cleaning liquid and the attached mud and sand on the polyethylene waste. After the washing is completed, the multi-section lifting rod continues to rise to the highest point, and the drying fan is started to blow hot air from the air outlet pipe to dry the polyethylene waste.

[0031] After drying is completed, the electric telescopic rod extends out to drive the unloading guide groove through the unloading connecting port to the lower side of the rotating net cylinder near the end cover mechanism, and then the telescopic cylinder extends out to open the sealed end cover, and the polyethylene waste enters the crushing box from the unloading guide groove. At this time, the crushing roller in the crushing box is driven to rotate by the crushing motor, and the crushing blades distributed on it crush the polyethylene waste. After crushing, it falls to the bottom of the crushing box and is preheated by the preheating electric heating tube. After preheating, it enters the double spiral cylinder below and is hot-melted by the electric heating tube. At the same time, the hollow spiral shaft rotates to push the hot-melt polyethylene material to the granulation extruder for extrusion and granulation, completing the recycling and granulation process.
