Heat pipe type three-cylinder dryer

Abstract

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.

Description

technical field [0001] The invention relates to a three-cylinder dryer, in particular to a heat pipe type three-cylinder dryer. Background technique [0002] Nowadays, in the processing and production fields of grain, food, chemical industry, medicine, agricultural and sideline products, pasture, etc., it is necessary to heat and dry the materials; the hot air used by the three-cylinder dryer is the hot air exchanged by the heat exchanger outside the equipment. The drying equipment is large in size, low in heat energy utilization and high in power consumption, and the quality of the dried material is poor, which affects the uneven drying moisture of the material. The high-temperature material after drying cannot be cooled. [0003] At present, there are three-cylinder dryers on the market that are equipped with a heating chamber outside the heat pipe three-cylinder drying chamber. The heating tank conducts heat conduction heating to the cylinder body of the heat pipe three-...

AI Technical Summary

Problems solved by technology

The heat conduction area of ​​the heating plate at the lower end of the heating tube is limited, and the heating plate with a small heat exchange area only inputs a small amount of heat. The heat transfer medium affects the heat energy in the heat conduction tube to the inner cavity of the tube due to the limited heating area. The heat conduction heating of the heat conduction working medium causes the total heat energy of the heat conduction working medium to be insufficient, causing the heating tube to fail to output a large amount of heat energy, and the material cannot get enough heat energy, which affects the drying efficiency of the material in the three-cylinder drying chamber of the heat pipe
