Heat-pipe-type drum drying bin

Abstract

The invention discloses a heat-pipe-type drum drying bin. The heat-pipe-type drum drying bin comprises a heat pipe heating device and a drum drying bin; the heat pipe heating device is installed in abin of the drum drying bin; the heat pipe heating device comprises a heating pipe and a heat conducting pipe; the heating pipe comprises a metal pipe, a heat conducting work medium and a heating sealhead; the heat energy carried by the medium conducts heat conduction and heating for materials in the drum drying bin through the heat conducting pipe and the heating pipe of the heat pipe heating device; and the heat dissipation area of a heater with heating strips is increased by 8-35 times, the heater transmits heat energy to the heat conducting work medium, and the heat conducting work mediumconducts the heat conduction and heat transfer of 'liquid vapor phase change' in the inner cavity of the pipe. The heating pipe in the drum drying bin can conduct heat conduction and heating for the materials, and can stir the materials during the material drying working, the drying quality of the materials in the drum drying bin is uniform, the drying efficiency of the materials is improved, thedrying effect of the materials is optimized, and green drying, energy saving and environmental protection are achieved.

Description

technical field [0001] The invention relates to a drum drying bin, in particular to a heat pipe type drum drying bin. Background technique [0002] Nowadays, in the processing and production fields of grain, food, chemical industry, medicine, agricultural by-products, pasture and so on, it is necessary to heat and dry the materials. The heat energy used by the drum drying chamber of the drum dryer is the heat generated by the peripheral heating equipment through the heat exchange into hot air. 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. , The uneven drying moisture that affects the drying of materials. [0003] Some drum dryers use heat energy to heat the drum body through the medium in the peripheral heating tank when the material in the drum drying chamber is dried. The small heat conduction area of ​​the body causes the slow conduction speed of heat energy. The tumbl...

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 conduction working fluid 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-conducting working medium causes the total heat energy of the heat-conducting working medium to be insufficient, causing the heating tube to fail to output a large amount of heat energy, and the material cannot receive enough heat energy, which affects the drying efficiency of the drum drying chamber
