[0002] Coal gangue, a solid waste generated during coal mining and washing, not only occupies land resources but also may cause environmental pollution when it is piled up. Pretreatment and drying are key preliminary steps to achieve its efficient utilization.

[0003] In the traditional coal gangue pretreatment process, the removal of metal impurities mostly relies on manual sorting or large magnetic separation equipment, which has problems such as low efficiency, high cost, and incomplete separation, and is prone to wear and tear on subsequent processing equipment or affecting product purity.

[0004] Existing coal gangue drying equipment mostly adopts static stacking drying or single airflow drying methods, which are prone to uneven heating due to material accumulation, resulting in low drying efficiency and high energy consumption. Furthermore, the internal moisture of large or agglomerated coal gangue is difficult to evaporate quickly, affecting the subsequent processing effect. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a coal gangue pretreatment and drying device that can quickly heat and dry coal gangue and collect magnetic metal fragments inside the coal gangue.

A first drying cotton board is fixedly attached to the inner wall of the drying and posttreatment box. A first magnetic magnet is fixedly connected to the lower end of the first drying cotton board. A drying stirring shaft is provided inside the drying and posttreatment box. A stirring blade is fixedly connected to the drying and stirring shaft. Second drying cotton is attached to multiple surfaces of the stirring blade. Two second magnetic magnets are attached to the inner wall of the drying and posttreatment box. A pretreatment heating channel is fixedly connected to the outer wall of the drying and posttreatment box. Two layers of heating wires are provided in the inner interlayer of the pretreatment heating channel. A rotating shaft is provided inside the pretreatment heating channel.

[0012] Beneficial effects:

[0013] 1. The inner wall of the post-drying treatment chamber is fixedly attached to the first drying cotton board, and a drying stirring shaft is installed on the inner side as the core drying component. Through the continuous rotation of the drying stirring shaft, the coal gangue is fully turned over and dispersed in the device, increasing its contact with hot air.
