产品概述/Product overview
SZG双锥真空干燥机是我厂在结合国内同类产品技术所开发的新一代干燥装置,双锥真空采用皮带--链条两弹性联接方式,因而设备运行平稳。特别设计的工艺,充分体现了两支轴的良好同心,热媒及真空系统均采用可靠的机械密封或美国技木的旋转接头。在此基础上,我们开发了SZG--A它既可无级调速,又能进行恒温控制。
本厂可另行在罐内为您特别设计“抄板”结构。
SZG rotary vacuum dryer is a drying device of new generation developed by our factory based on technologies of similar domestic products. The two cone-vacuum adopts belt-chain double elastic connection method, therefore the equipment can run in a stable manner. The specially designed process fully shows the good concentricity of the two shafts. Thermal media and vacuum system all adopt reliable mechanical sealing or rotating connector of American Technology. Based on this, we developed SZG—A which is capable of stepless speed regulating and thermostatical control.
Our factory may provide you with special “shovelling plate” structure additionally inside the tank.
工作原理 /operating principle
在密闭的夹层中通入热能源(如热水,低压蒸汽或导热油)热量经内壳传给被干燥物料。在动力驱动下,灌体作缓慢旋转,罐内物科不断地混合从而达到强化干燥的目的。
物料处于真空状态,蒸汽压下降使物料表面的水份(容剂)达到饱和状态而蒸发了,并由真空泵及时排出回收。物料内部的水份(溶剂)不断的向表面渗透、蒸发、排出、三个过程不断进行,物料在短时间内达到干燥目的。
Supply heat energy (such as hot water, steam of low pressure or heat conduction oil) into the closed interlayer. The heat will be transferred to materials to be dried by inner shell. The tank body will be driven to rotate slowly. The materials inside the tank are mixed to strength drying purpose.
The materials are under vacuum status. Steam pressure will decrease which make the water on material surface (solvent) become saturated and then evaporate. The water will be discharged and recycled by the vacuum pump immediately. Water (solvent) inside the material is permeated, evaporated and discharged from the surface. The said three processes happen constantly and the materials will be dried in a short period.
