Abstract
The invention provides a conduction heating type cylinder dryer. The conduction heating type cylinder dryer comprises a cylinder drying bin, a heating tank, a heat preservation cover, a rear support,a driving device, supporting wheels, a front support and an exhaust device. The cylinder drying bin comprises a cylinder, spiral blades, heating pipes, a supporting frame, a transmission shaft and a rolling path. Each heating pipe comprises a metal pipe, a heat conduction working medium and a heating device. Heat energy conducts heat conduction and heating on materials through a barrel in the cylinder of the cylinder drying bin and the heating pipes on the barrel, the heat dissipation area of a heater with heating strips is increased by 8-35 times, the heater conducts enough heat to the heat conduction working media, the heat conduction working media conduct heat conduction and heat exchange of liquid-vapor phase change in the cavities of the pipes, the heat energy is conducted to the materials in the cylinder through the heating pipes for heat conduction and heating, the material drying efficiency is improved, the material drying effect is optimized, the material drying moisture uniformity is improved, the material drying efficiency is improved, the material drying effect is optimized, and the conduction heating type cylinder dryer is environmentally friendly in drying, and is energy-saving.
Description
technical field [0001] The invention relates to a drum dryer, in particular to a conduction heating drum dryer. Background technique [0002] At present, the heat exchange of the drum drying chamber of the drum dryer on the market is mostly carried out by tube-and-tube or interlayer heat conduction heating, but their heaters are large in size, small in heat dissipation area, and low in efficiency of heat energy use. The heating tube of the tubular drum drying bin and the cylinder welding joint of the drum drying bin are also susceptible to air leakage damage caused by welding stress and stress generated by corrosion products. The heating tube is worn by the material during the drying process of heat conduction and heat exchange materials. , there is a leakage of a heating pipe, the heating pipe is not easy to repair, resulting in the drum drying chamber of the entire drum dryer cannot be used normally. [0003] The heating tube in the drum drying bin of the new drum dryer t...
