Heat pipe type three-cylinder drying bin

Abstract

The invention provides a heat pipe type three-cylinder drying bin. The heat pipe type three-cylinder drying bin comprises a heat pipe type heating device and a three-cylinder drying bin body. The heatpipe type heating device comprises a heating pipe and a heat conduction pipe; and the heating pipe comprises a metal pipe, a heat conduction working medium and a heating sealing head. The heat pipe type heating device is mounted in a bin of the three-cylinder drying bin body. Heat energy carried by the medium conducts heating conduction and heating on materials in the three-cylinder drying bin body by the heat conduction pipe and the heating pipe of the heat pipe type heating device; and the heat dissipation area of a heater with heating strips is increased by 8 times to 35 times, the heaterconducts the heat energy to the heat conduction working medium, and the heat conduction working medium carries out "liquid vapor phase change" heat conduction heat exchange in a pipe inner cavity. Theheat energy is conducted to the materials in a roller through the heating pipe for conducting heat conduction and heating; and the heating pipe in the three-cylinder drying bin body can conduct heatconduction and heating on the materials and also play the role in stirring the materials when the materials are dried, 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 drying warehouse, in particular to a heat-pipe-type three-cylinder drying warehouse. Background technique [0002] At present, in the processing and production fields of grain, food, chemical industry, medicine, agricultural and sideline products, and pasture, it is necessary to heat and dry materials. The heat energy used in the three-cylinder drying bin of the tumble dryer is the hot air generated by the heat energy generated by the peripheral heating equipment through the heat exchanger. Poor, the drying moisture that affects the drying of the material is uneven. [0003] The heat energy used in the drying of the materials in the three-cylinder drying chamber of some drum dryers heats the cylinder of the drum drying chamber through the medium in the external heating tank. The loss is large, and the heat conduction area of ​​the cylinder is small, resulting in a slow conduction speed of heat energy. The tu...

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 ...
