[0002] The hot-pressing dewatering device for lignite processing is a device for removing water in lignite under high temperature and high pressure conditions. Its main principle is to use hot-pressing technology to effectively squeeze out water in lignite under high temperature and high pressure, thereby improving the energy density and combustion efficiency of lignite. Hot-pressing dewatering can significantly improve the storage and transportation performance of lignite, reduce transportation costs, and improve its efficiency in energy utilization.

A water collecting chamber is provided below the water filtering ports. A discharging cavity is fixedly connected below the material dropping port. In the prior art, lignite is prone to sticking to the wall after drying and discharging, which affects the drying efficiency of subsequent lignite. An L-shaped scraper is fixedly connected to the side of the rotating frame. The scraper extends into the drying chamber. The rotating frame rotates, which drives the scraper to rotate in the drying chamber. The scraper removes the residual coal ash on the side wall of the drying chamber during rotation, thereby preventing lignite from accumulating on the inner wall of the drying chamber and improving the drying effect of subsequent lignite.
