Heat pipe type three-cylinder dryer

A heat pipe type three-cylinder drying machine comprises a heat pipe three-cylinder drying bin, roller paths, a gear ring, a three-way connector device, a discharging device, an exhaust device, a support, riding wheels and a driving device. The heat pipe three-cylinder drying bin comprises heating devices, a three-cylinder drying bin body and spiral blades. Heat energy carried by a medium carriesout heat conduction and heating on materials in the three-cylinder drying bin body through heat conduction pipes and heating pipes of the heating devices; heaters with heating strips conduct heat energy to a heat conduction working medium, the heat conduction working medium carries out heat conduction and heat exchange of liquid-vapor phase change in inner cavities of the pipes, and the heat energy is conducted to materials in a roller through the heating pipes for heat conduction and heating; and when a certain heating pipe is damaged to cause leakage, use of the whole three-cylinder drying bin body is not influenced. When the heating devices in the three-cylinder drying bin body carry out heat conduction and heating on the materials, the effect of stirring the materials during material drying work is achieved, the drying quality of the materials in the three-cylinder drying bin body is uniform, the material drying efficiency is improved, and the material drying effect is optimized.
