Four cylinder drying machine

Abstract

The invention relates to a four cylinder drying machine. The four cylinder drying machine comprises a four cylinder drying bin, a feeding exhaust device, a gear ring, a heating device, a support, a supporting wheel bracket and a driving device. Under the drive of the driving device, the four cylinder drying bin can rotate to work under the support of supporting wheels on the supporting wheel bracket. Heat energy generated by the heating device conducts heating and heat conduction on a heat-conducting medium in a heating bin through a bin body of the heating bin. The heat energy carried by theheat-conducting medium is used for conducting heat conduction and heat exchange on heat pipes in a double cylinder bin through an outer cylinder body and an inner cylinder body of an inner cylinder bin. The heat conversion efficiency is high, the loss is small, and the heat conduction and heat exchange speed is increased. When the four cylinder drying machine dries materials, excess heat air is not needed, the heat loss taken away by exhaust can be ignored, the overall effective utilization rate is 80%-90%, the exhaust device exhausts moisture out of the four cylinder drying bin, a guide platestirs and pushes the materials in the drying process, the drying uniformity of the materials is improved, by means of continuous drying, the material drying efficiency is improved, and the material drying effect is optimized.

Description

technical field [0001] The invention relates to a dryer, especially a four-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 products. Most of the three-cylinder dryers on the market now use external heat exchange for hot air. The heat exchange efficiency of heat energy is low, the use of heat energy for hot air convection drying is one-time, and the heat energy required for drying will increase a lot, which will affect the uneven drying moisture of materials. During the use of the heat pipe dryers currently on the market, if a heat pipe leaks, it is not easy to repair, and the entire drying chamber will be scrapped and cannot be used. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies in the prior art, and provide a four-cylinder dryer, which uses conduct...
