Problems solved by technology

[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 heat pipe dryers currently on the market, if a heat pipe leaks, it is not easy to repair, and the entire three-drum drying chamber will be scrapped and cannot be used.

Abstract

The invention relates to a four cylinder vacuum drying machine. The four cylinder vacuum drying machine comprises a four cylinder drying bin, a feeding device, a discharging device, a gear ring, a heating device, a bracket, a supporting wheel bracket, a driving device, a gas-guide tube and a vacuum unit. 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 heats a heat-conducting medium through a bin body of the heating bin of the four cylinder drying bin; the feeding device is installed on a feed inlet of the four cylinder drying bin, and the discharging device is installed at a discharge hole of the four cylinder drying bin. One end of thegas-guide tube penetrates through an elbow of the feeding device, and the other end of the gas-guide tube is connected to the vacuum unit. The relative air pressure of gas in the four cylinder dryingbin is 0.025 Mpa-0.098 Mpa; The heat conversion efficiency of the four cylinder vacuum drying machine is high, the loss is small, and the heat conduction and heat exchange speed is increased. By meansof continuous vacuum drying, the material drying efficiency is improved, the material drying effect is optimized, and the purpose of drying the materials rapidly is achieved.

Description

technical field [0001] The invention relates to a dryer, in particular to a four-cylinder vacuum 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 heat pipe dryers currently on the market, if a heat pipe leaks, it is not easy to repair, and the entire three-cylinder drying chamber will be scrapped and cannot be used. [0003] The energy consumption index of vacuum low-temperature conduction drying is 2800-4000kj / kg, while that of hot-air convection drying is 4000-7500kj / kg; the ef...
