[0029] The overall effect achieved by the entire Embodiment 1 is that by starting the first driving motor 8, the first rotating shaft 6 drives the permanent magnet guiding roller 7 to rotate. When the waste residue is crushed and then falls on the permanent magnet guiding roller 7 through the material guiding hopper 5, during the rotation of the permanent magnet guiding roller 7, the waste residue falls due to gravity and is discharged from the corresponding discharging port, while the iron slag will be attracted by the permanent magnet guiding roller 7 and adsorbed on the permanent magnet guiding roller 7. The permanent magnet guiding roller 7 carries the iron slag to rotate until it collides with the discharging brush 12. The iron slag adsorbed on the permanent magnet guiding roller 7 is separated on the permanent magnet guiding roller 7 by the discharging brush 12 made of insulating material. At the same time, under the elastic force of the first return spring 10, the discharging brush 12 can always keep in close contact with the permanent magnet guiding roller 7, facilitating the separation of the iron slag, thereby achieving the purpose of separating the waste residue and the iron slag, without manual operation and improving the separation efficiency.

[0030] Embodiment 2: As Figure 1 - Figure 7As shown in the figure, the feeding mechanism 3 includes a rectangular groove 301 which is opened inside the feeding port 2. A rotating rod 302 is rotatably connected inside the rectangular groove 301. A vibrating plate 303 is fixedly sleeved on the outer surface of the rotating rod 302. A bearing plate 304 is fixedly connected inside the feeding port 2. A second return spring 305 is fixedly connected to the top of the bearing plate 304. The top end of the second return spring 305 is fixedly connected to the vibrating plate 303. The crushing mechanism 4 includes two second rotating shafts 401 which are both rotatably connected inside the machine housing 1. Two crushing rollers 402 are fixedly sleeved on the outer surfaces of the two second rotating shafts 401. The two crushing rollers 402 cooperate with each other. One end of each of the two second rotating shafts 401 movably penetrates through the machine housing 1. Two gears 403 are fixedly sleeved on the outer surfaces of the two second rotating shafts 401. The two gears 403 are meshed and connected. A second driving motor 404 is installed on one side of the machine housing 1. The output end of the second driving motor 404 penetrates through the machine housing 1 and is fixedly connected to one of the second rotating shafts 401. A heat energy conversion device 13 is arranged at the inner top of the machine housing 1. A cover plate 14 is bolted to the top of the machine housing 1. A guiding block 15 is fixedly connected to the inner bottom of the machine housing 1. The guiding block 15 is inclined. A first discharge port 16 is arranged at the bottom of the machine housing 1. A second discharge port 17 is arranged at the bottom of the machine housing 1.

[0031] The effect achieved by the entire embodiment 2 is that when adding waste residue into the machine housing 1 through the feeding port 2 by setting the feeding mechanism 3, the vibrating plate 303 is supported by the second return spring 305, and then the vibrating plate 303 can vibrate continuously, which is convenient for improving the feeding speed and effectively preventing the feeding port 2 from being blocked. By setting the crushing mechanism 4 and starting the second driving motor 404, the second driving motor 404 drives one of the second rotating shafts 401 to rotate. One of the second rotating shafts 401 drives one of the gears 403 to rotate. Since the two gears 403 are meshed and connected, the two crushing rollers 402 rotate relatively, which is convenient for crushing and grinding the waste residue. By setting the heat energy conversion device 13, during the process of crushing the waste residue, the heat inside it is dissipated. The heat conducting rod is fixedly connected to the bottom of the heat energy conversion device 13, and the heat conducting rod absorbs the heat of the waste residue. The heat energy conversion device 13 is convenient for converting the absorbed heat energy. The bolted cover plate 14 is convenient for taking out the heat energy conversion device 13. Under the action of the guiding block 15, it is convenient for the waste residue to be discharged through the first discharge port 16, and the iron slag is discharged through the second discharge port 17.

[0032] Working principle: When in use, install the heat energy conversion device 13 inside the casing 1, and install the cover plate 14 on the top of the casing 1 through bolts. When separating the waste residue, start the first drive motor 8 and the second drive motor 404, and then add the waste residue into the casing 1 through the feed port 2. The vibration plate 303 is supported by the second return spring 305, so that the vibration plate 303 can vibrate continuously, improving the feeding speed. When the waste residue falls between the two crushing rollers 402 through the feed port 2, drive one of the second rotating shafts 401 to rotate through the second drive motor 404. One of the second rotating shafts 401 drives one of the gears 403 to rotate. Since the two gears 403 are meshed and connected, the two crushing rollers 402 rotate relatively to crush and grind the waste residue. When the waste residue is crushed, it falls on the permanent magnet guide roller 7 through the material guide hopper 5. At the same time, the first rotating shaft 6 drives the permanent magnet guide roller 7 to rotate. During the rotation of the permanent magnet guide roller 7, the waste residue falls due to gravity and is discharged from the first discharge port 16, while the iron slag will be attracted by the permanent magnet guide roller 7 and adsorbed on the permanent magnet guide roller 7. The permanent magnet guide roller 7 carries the iron slag to rotate until it collides with the unloading brush 12. The iron slag adsorbed on the permanent magnet guide roller 7 is separated on the permanent magnet guide roller 7 through the unloading brush 12 made of insulating material and is discharged from the second discharge port 17. It does not require manual operation, improving the separation efficiency. At the same time, during the rolling and crushing process of the waste residue, the heat inside it is dissipated, and the heat energy conversion device 13 absorbs the heat of the waste residue, facilitating the energy conversion of the absorbed heat.

[0033] The above is only the preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
