Heat-pipe type three-cylinder dryer

Abstract

The invention discloses a heat-pipe type three-cylinder dryer comprising a heat-pipe type three-cylinder drying bin, a feeding exhaust device, a support, a heating device, a driving device, a roller rack and a moving device. The heat-pipe type three-cylinder drying bin comprises a shell, a combined-type drying bin, 2-5 sets of roller paths, 1-2 sets of gear rings and a heat-conducting medium; the heat-conducting medium is in the inner cavity between the shell and the combined-type drying bin; the feeding exhaust device comprises a vacuum feeding and discharging device, a ventilation pipe and an exhaust device; the roller paths and the gear rings are arranged on the shell of the heat-pipe type three-cylinder drying bin. Under the driving of the driving device, the heat-pipe type three-cylinder drying bin can rotate to operate under the support of rollers on the roller rack; materials are fed or discharged from the heat-pipe type three-cylinder drying bin through the vacuum feeding and discharging device, humidity is discharged from the combined-type drying bin through the exhaust device, and the materials can be continuously dried, so that drying efficiency of the materials is improved, and drying effect of the materials 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] Now on the market, there are drying equipment for materials such as grain, chemical products, coal, gravel, sand, mineral products, pasture, crops, and local specialties. The heat exchange outside the equipment of the three-cylinder dryer on the market is hot air, and the heat exchange The heat efficiency is low, the use of heat energy is one-time, and the heat energy required for drying will increase a lot, which will affect the uneven drying moisture of materials. [0003] The patented heat pipe type three-cylinder vacuum dryer (patent application number 2016208123269) that I applied for includes a heat pipe type three-cylinder drying chamber, an air duct, a bracket, a vacuum unit, a heating device, a driving device, a vacuum feeding and discharging device, and a moving device. The vacuum feeding and discharging devi...
