Embodiment 1
[0027] Under the condition that the room temperature is about 27°C, the mixed solid waste first passes through a low-temperature thermostatic chamber with a temperature of 27°C for 5 minutes, and the temperature of the mixed solid waste is completely kept at 27°C. At this time, the main conveyor belt transports the mixed solid waste to a high-temperature room with a temperature of 55 °C, and collects data through a PC-based data acquisition system. The sensor data shows that metal materials such as stainless steel, lead, aluminum, gold, copper, silver, etc. will rise by 15°C within 1.5-4min, and the heating rate is 3.75-10°C / min. At this time, several groups of solid waste sorting hands can sort out metal materials such as stainless steel, lead, aluminum, gold, copper, silver, etc., and move them to the secondary conveyor belt for conveying metal materials. The auxiliary conveyor belt then transports the metal material to the metal material collection room.
Embodiment 2
[0029] Under the condition that the room temperature is about 27°C, the mixed solid waste first passes through a low-temperature thermostatic chamber with a temperature of 27°C for 5 minutes, and the temperature of the mixed solid waste is completely kept at 27°C. At this time, the main conveyor belt transports the mixed solid waste to a high-temperature room with a temperature of 55 °C, and collects data through a PC-based data acquisition system. The sensor data shows that inorganic materials such as glass, soil, concrete, etc. will rise by 15°C within 5.5-8.5min, and the heating rate will be 1.76-2.72°C / min. At this time, several groups of solid waste sorting hands can sort inorganic materials such as glass, soil, concrete, etc., and move them to the secondary conveyor belt for transporting inorganic materials. The auxiliary conveyor belt then transports the inorganic material to the inorganic material collection chamber.
Embodiment 3
[0031] Under the condition that the room temperature is about 27°C, the mixed solid waste first passes through a low-temperature thermostatic chamber with a temperature of 27°C for 5 minutes, and the temperature of the mixed solid waste is completely kept at 27°C. At this time, the main conveyor belt transports the mixed solid waste to a high-temperature room with a temperature of 55 °C, and collects data through a PC-based data acquisition system. The sensor data shows that organic polymer materials such as rubber, [polymer] polypropylene, and epoxy resin rise by 15°C within 10-14min, and the heating rate is 1.07-1.5°C / min. At this time, several groups of solid waste sorting hands can sort out organic polymer materials such as rubber, [macromolecule] polypropylene, epoxy resin, etc., and move them to the secondary conveyor belt for conveying organic polymer materials. The secondary conveyor belt then transports the organic polymer material to the organic polymer material coll...
