Continuous heat pipe type hot air drying machine

Abstract

The invention provides a continuous heat pipe type hot air drying machine, which consists of a heat pipe vacuum drying cabin, an air inlet device, a support frame, a discharging device, a heating device, a driving device, rails and an exhaust device, wherein the discharging device, the air inlet device and the exhaust device are arranged on material inlet and outlet openings of an inner cabin; the rails arranged on a case of the heat pipe vacuum drying cabin is arranged on the support frame; the driving device is used for driving the rails arranged on the case; the heating device is used for directly heating the case of the heat pipe vacuum drying cabin. The heat exchange is directly performed in the drying cabin; the heat exchange area is increased by 12 to 60 times; the heat conduction and heat exchange speed of material drying is accelerated. The materials are fed into or discharged from the vacuum drying cabin through the discharging device, and the materials can be subjected to continuous hot air drying. A heat radiation pipe and a spiral blade have the stirring function; no dead corner exists during the material drying; the material drying time is shortened, so that the material drying quality is uniform; the material drying efficiency is improved; the material drying effect is optimized; the dried materials are cooled; the effects of green drying, energy saving and environment protection are achieved.

Description

technical field [0001] The invention relates to a dryer, in particular to a continuous heat pipe hot air 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. The heating of materials on the market today is to dissipate heat through metal bundle tubes placed in parallel, or The heat exchange outside the equipment is done by hot air for drying. The heat conversion efficiency is low, the exhaust efficiency is low, and the heat energy required for drying increases a lot. Evenly, the dried material will not be cooled. [0003] The patented heat pipe vacuum drying chamber that I applied for consists of an outer shell, an inner chamber, a highly airtight unloading device, an air guide pipe and a heat-conducting working fluid. The appearance shape of the heat pipe vacuum drying chamber is cylindrical, and its two ends are tapered. The shell i...
