When the screening drum rotates, the scraper drops the polyethylene wax attached to the inner wall of the screening drum and the screening net. When the scraper contacts the pushing block, the screening drum is driven to vibrate up and down through the pushing block. The screening drum moves up and down along the lifting rod through the connecting piece, driving the extension and compression of the spring, thereby intensifying the up and down vibration of the screening drum, preventing the polyethylene wax from adhering to the lower wall of the screening drum, and facilitating the dispersion of the polyethylene wax.

The middle large piece of polyethylene wax enters the discharge pipe from the inner discharge pipe and is discharged. The outer discharge pipe allows the polyethylene wax screened by the screening net to enter the two sides of the isolation cylinder, enter the discharge cylinders on both sides from the inclined platform, and be discharged from the discharge cylinders at different positions, so that the screened polyethylene wax can be dispersed and collected.
