Continuous heat pipe drying machine

Abstract

The invention discloses a continuous heat pipe drying machine. The continuous heat pipe drying machine comprises a drying bin, an exhaust device, a feed device, a three-way pipe, a bracket, a support roller bracket, a fan, a heating device, a sealing device and a drying device. The drying bin includes an inner bin, a shell and a heat conducting medium. The heat conducting medium is in an inner cavity between the shell and the inner bin. The heating device heats the shell of the drying bin; and one end of the inner bin is a drying area, and the other end is a cooling area. The fan is fixedly mounted out of the inner bin of the cooling area of the drying bin. The driving device drives a gear ring of the drying bin; and the drying bin is supported by the support roller bracket, and rotates on the support roller bracket. When materials are dried, the heat exchange area is increased, the heat conduction and exchange speed of heat energy is accelerated, the material drying efficiency is enhanced, and the quick material drying purpose is achieved; the drying bin rotates under the effect of external force; the materials stirred by a heat dissipating pipe and a spiral blade are not easy to cake during drying in the inner bin, so that the material drying quality is improved; and the heat conduction, the heat exchange and the cooling are performed for the dried materials in the cooling area.

Description

technical field [0001] The invention relates to a dryer, in particular to a continuous heat pipe dryer. Background technique [0002] Drying equipment for materials such as grain, chemical products, coal, gravel, sand, mineral products, pasture, crops, and local specialties on the market. Now the materials on the market are heated by metal pipes for heat exchange, and the heat conduction and heat dissipation efficiency is low. If the exhaust efficiency is low, the heat energy required for drying will increase a lot, and the dried materials will have dead angles, and the materials will easily form agglomerates, which will affect the uneven drying moisture of the materials. Now the material is cooled in a normal pressure environment, it will be affected by the moisture in the surrounding air, and the dry material will be damaged by moisture; if it is directly cooled in a dry state, the quality of the dried material will be further protected. [0003] Heat pipe technology is a...
