In this way, the light garbage can be separated from the mixed waste and transported out of the drop box 3 from the air outlet 34, and the clean iron in the mixed waste is transported out of the drop box 3 from the discharge port 33.

[0036] Specifically, refer to Figure 5 In this embodiment, the cyclone 5 is a hollow structure. The cyclone 5 includes an exhaust port section, an air inlet section, a straight section, a connecting section, a tapered section, and a discharge section arranged from top to bottom. A built-in liner is provided in the air inlet 32 section. The diameters of the tapered section and the discharge section gradually decrease from top to bottom. The bottom of the discharge section is connected to the ash discharge valve 6 by fasteners, and the outlet of the exhaust port section is connected to the fan 2 through an exhaust duct 8.

[0037] In the above-mentioned cyclone 5 structure, light garbage is transported from the drop box 3 to the cyclone 5 through the connecting channel, enters the cyclone 5 from the air inlet section, and the connecting section is welded between the straight section and the conical section. The separated material is discharged from the cyclone 5 through the discharge section, and the gas is discharged through the outlet of the exhaust section.

[0038] Specifically, refer to Figure 7 In this embodiment, the ash discharge valve 6 includes a shell 61, a rotating body 62 arranged in the shell 61, and a driving motor 63 arranged outside the shell 61 and connected to the rotating body 62, and the driving motor 63 drives the rotating body 62 to rotate.

[0039] Specifically, refer to Figure 9In this embodiment, the rotating body 62 includes a rotating shaft 621 and a plurality of rotating blades 622 disposed on the rotating shaft 621. The rotating shaft 621 extends axially to the exterior of the housing 61. The plurality of rotating blades 622 are arranged in a circular array along the radial direction of the rotating shaft 621. Connecting pieces 623 are provided between adjacent rotating blades 622. One end of the rotating shaft 621 is connected to the drive motor 63 via a shaft key. The drive motor 63 drives the rotating shaft 621 to rotate, causing the rotating shaft 621 to drive the rotating blades 622 to rotate about the rotating shaft 621.

[0041] Specifically, in this embodiment, a discharge hopper 65 for discharging materials is provided at the bottom of the ash discharge valve 6 .

[0042] The structure of the above-mentioned ash discharge valve 6 is that the rotation of the rotary body 62 will discharge the materials separated and dropped from the cyclone 5, and the sealing design inside the ash discharge valve 6 ensures the air tightness of the air separation device system to prevent ash and dust. The drive motor 63 drives the rotary body 62 to rotate and discharge the materials separated and dropped from the cyclone 5 into the discharge hopper 65, completing the unloading efficiency safely and efficiently. The ash discharge valve 6 is provided with a speed monitoring proximity sensor 64. Since the garbage separated by the scrap steel crusher air separation system also contains a certain proportion of metal, the ash discharge valve 6 of the scrap metal crusher air separation device will also produce metal wear during operation. In addition, due to the uncontrollable nature of the crushed material, sometimes large and long materials will fall into the ash discharge valve 6 of the scrap metal crusher air separation device, causing the large or long materials inside the ash discharge valve 6 to block the machine and cause the cyclone 5 and pipeline of the air separation device to accumulate and block. In this case, a speed monitoring device is provided to monitor the operating status of the ash discharge valve 6 to ensure that the ash discharge valve 6 is properly operated. Now, it is determined whether to execute relevant actions according to different operating states. For example, when the speed is zero, the main fan 2 of the air separation unit is shut down for 10 seconds, and a fault message is sent to the operator for maintenance. When the drive motor 63 drives the rotary shaft 621 to rotate, the proximity sensor 64 receives a continuous pulse signal and transmits the signal to the PLC system. At this time, the PLC system determines that the equipment is in an operating state. When the rotary shaft 621 stops rotating, the proximity sensor 64 cannot receive a continuous pulse signal and transmits the signal to the PLC system. At this time, the PLC system determines that the equipment is in a shutdown state.
