Hot-pressing dehydration device for lignite

The lignite hot-pressing dehydration device comprises a main body, a feeding port and a drying chamber, the feeding port is formed in the lateral upper portion of the main body, water filtering ports are formed in the two sides of the bottom of the drying chamber, a discharging port is formed in the lower portion of the drying chamber, water collecting chambers located below the water filtering ports are arranged on the two sides of the discharging port, and the lower portion of the discharging port is fixedly communicated with a discharging cavity. In the using process of a lignite hot-pressing dehydration device in the prior art, lignite is prone to adhering to the wall after being dried and discharged, the dried lignite is accumulated on the inner wall of a cavity, and the subsequent lignite drying efficiency is affected. The rotary frame can drive the scraper to rotate in the drying chamber in the rotating process, residual coal slag on the side wall of the drying chamber can be scraped away in the rotati
