[0002] A shield machine is a tunnel boring machine that uses the shield method. According to the working principle, shield machines are generally divided into hand-dug shields, extrusion shields and semi-mechanical shields. Its main structure includes a shield cutter head, a screw conveyor and a slag pretreatment system connected end to end in sequence. The slag pretreatment system is connected to a water collection device. In order to improve the utilization rate of the slag, it is generally necessary to dry the slag, but the existing drying devices have certain inconveniences when used.

[0003] In Chinese utility model patent application number: CN202221017317.2, a shield slag drying and processing device based on the eddy current principle is disclosed. By setting a drying device at the tail of the shield machine for drying operations, the shield waste slag is synchronously dried and dehydrated in the tunnel for recycling in tunnel excavation operations, which greatly improves the efficiency and value of the shield waste slag and reduces the pollution and safety risks in the process of shield waste slag treatment. However, the slag drying and processing device cannot sort the imported soil slag when in use. The volume of the soil slag is different, which easily causes uneven drying. In addition, it takes a long time to dry a larger volume of soil slag, which easily affects work efficiency and wastes energy. In addition, the slag drying and processing device cannot cool the dried soil slag when in use. The high-temperature soil slag is not convenient for subsequent recycling and storage. For this reason, we propose a shield slag drying and processing device based on the eddy current principle. Utility Model Content
