It includes an electromagnet 51 arranged on the driven roller 103; the side of the second transport device 10 away from the secondary crusher 4 is provided with a fifth transport device 13 for separating garbage, and the bottom of the first magnetic separator 5 is arranged There is a third transport device 11 for transporting garbage to the iron-plastic stripper 6, a sixth transport device 14 is provided below the second magnetic separator 7; the trommel 8 is provided with a feeding end and a discharging end, and the discharging end is provided with There is a seventh transport device 15 for transporting the garbage out, and the wall of the drum screen 8 is provided with a screen hole 82 .

When recycling garbage, the garbage is first put into the hopper 1, and then the garbage in the hopper 1 is transported by the first transport device 9 and sent to the shredder 2. The shredder 2 can remove large pieces of waste during operation. The plastic garbage is shredded into small pieces of garbage. For those with metal connected to the plastic, the shredder 2 can also make the metal fall off from the plastic. However, due to some plastics containing iron wires and other metals, it is difficult for the shredder 2 to remove the metal from the plastic. The iron wire falls off from the plastic, so when the garbage is shredded, it enters the primary crusher 3 and the secondary crusher 4 through the first transport device 9. The primary crusher 3 performs preliminary crushing, and the secondary crusher 4 performs primary crushing. Deep crushing, after crushing, the plastic containing iron wire and other metals is crushed into small pieces, and when the garbage is transported on the second transport device 10 and passes through the first magnetic separator 5, as shown in FIG. The plastic waste is attracted by the electromagnet 51, and moves to the bottom of the driven roller 103 along with the conveyor belt 102. When the conveyor belt 102 is away from the driven roller 103, the steel and metal will automatically fall into the third transportation device 11. Other The garbage is thrown to the fifth transport device 13 along with the conveyor belt 102 for recycling. The plastic waste containing steel and metal falling into the third transport device 11 is transported to the iron-plastic stripping machine 6 for stripping. Machine 7, as shown in FIG. 5, the iron and steel metal is attracted by the electromagnet 51, and moves to the bottom of the driven roller 103 along with the conveyor belt 102. When the conveyor belt 102 is away from the driven roller 103, the iron and steel metal will automatically fall into the The sixth conveying device 14, and other garbage will be thrown to the trommel 8 along with the conveyor belt 102. As shown in FIG. During the process, the sediment impurities tightly adhered in the garbage will be stripped to obtain clean and recyclable garbage and transported out through the seventh transport device 15 for recycling.

In this embodiment, specifically, as shown in FIG. 3 and FIG. 4 , the iron-plastic peeling machine 6 includes a peeling drum 61 , and the peeling drum 61 is provided with a peeling chamber 611 and a collecting chamber 612 at the bottom of the peeling chamber 611 . A separation roller 62 is rotatably connected inside the cavity 611. The separation roller 62 is distributed with a number of separation pieces 63 at intervals along the axial direction. The separation piece 63 is provided with a number of blades at intervals along the circumferential direction. The bottom of 611 is provided with a channel communicating with the collecting cavity 612 , the bottom of the collecting cavity 612 is provided with a discharge port 65 , and the top of the peeling cylinder 61 is provided with a feeding port 641 communicating with the peeling cavity 611 .

Under the high-speed rotation of the separation roller 62, the blade rotates and drives the separation knife 631 to rotate rapidly. The separation knife 631 arranged on the blade will peel off the plastic containing steel metal, because the separation knife 631 hits or cuts the iron in the plastic. A large impact force will be generated during the threading process, so the separating knife 631 is rotated and arranged on the separating blade, in order to reduce the wear of the separating knife 631 and prolong its service life. The stripped steel metal and plastics enter the discharge port 65 of the collecting chamber 612 through the channel to be transported out, and are transported to the second magnetic separator 7 through the fourth transport device 12 .

Furthermore, due to the high-speed rotation of the separation roller 62, if the feeding port 641 is set directly above the feeding hopper 64, the garbage will be easily thrown out from the feeding port 641 with the rotation of the separation roller 62, Therefore, the upper end of the feeding hopper 64 is closed and the feeding port 641 is provided on the side of the feeding hopper 64 .

Further, in order to transport the steel metal and plastic waste separated by the iron-plastic peeling machine 6 out of the discharge port 65, the collecting cavity 612 is set in the shape of a trumpet with a large upper and a small lower, and the discharge port 65 is set at the lowest position. The purpose of the bottom end is to prevent garbage from accumulating on both sides of the collecting cavity 612 .
