[0046] It should be noted that when the water droplets in the plastic are thrown out by the drying drum 74, they fall to the top of the purification filter plate 83 due to the influence of gravity. The water droplets are filtered by the setting of the purification filter plate 83 to prevent impurities from entering the water storage bin 86.

[0058] When the water droplets in the plastic are thrown out by the drying drum 74, they fall to the top of the purification filter plate 83 under the influence of gravity. The water droplets are filtered by the setting of the purification filter plate 83 to prevent impurities from entering the water storage bin 86. When the first roller 742 hits the second roller 85, it drives the purification filter plate 83 to vibrate to prevent impurities from accumulating on the surface of the purification filter plate 83 and causing the purification filter plate 83 to be blocked. The setting of the inclined plate 82 prevents impurities from adhering to the top of the sliding ring 81. When the sealing door plate 70 is opened, the electric slide rail 80 is started, and the electric slide rail 80 drives the purification filter plate 83 to move out of the processing box 3 through the sliding ring 81, which is convenient for the staff to clean the purification filter plate 83.

The staff does not need to clean it. At the same time, the water resources can be filtered and circulated to reduce the water resource loss of the equipment.

[0059] When the sealing door panel 70 is away from one side of the processing box 3, the sealing door panel 70 stops limiting the sliding bin 92, and the limiting spring 91 drives the sliding bin 92 to pop out of the storage box 2 through elasticity. When the discharge brush plate 77 discharges the plastic in the spin-drying drum 74, the plastic falls to the top of the sorting net 97 under the influence of gravity. The plastic is separated from the impurities by the setting of the sorting net 97, and there is no need for staff to separate and screen the plastic. After the plastic falls into the top of the sorting net 97, the mass of the sorting box 95 itself increases, and the sorting box 95 drives the second telescopic rod 94 to contract. When the second telescopic rod 94 contracts, the humidity detector 96 is started to detect the humidity of the plastic to avoid incomplete drying of the plastic. There is no need for staff to detect it, thereby reducing the labor intensity of the staff.
