干燥机设计说明书

摘要

筒体是卧式滚筒软化干燥机的机体。筒体内既进行热和质的传递又输送物料，筒体的大小标志着卧式滚筒软化干燥机的规格和生产能力。筒体应具有足够的刚度和强度。在安装和运转中必须保持轴线的直线性和截面的圆度。筒体的材料一般用Q235钢和普通低合金钢。提高了传热效率,充分发挥了蒸汽的潜能,降低了蒸汽消耗;提高了滚筒软化干燥机加热列管的管壁温度,增加设备处理量,提高物料软化效率。应根据油料的种类和含水量的不同，制定软化温度；当油料含水量低时，软化温度应相应高些，反之，应低些。根据油料含水量的不同，可进行加热润湿或加热去水。根据轧呸效果调整软化条件。轴的设计工作中的另一个重要方面是一根轴与另一根轴之间的直接联接方法。这由刚性或者弹性联轴器来实现的。联轴器是用来把相邻的两个轴端联接起来的装置。在机械结构中,联轴器被用来实现相邻的两根转轴之间的半永久性联接。

Title The Softening kettle

Abstract：T he tube body is the machine body that the softening kettle. The tube body inside since carry on heat and qualities' deliver and transport the material, the size of the tube body symbolizes the specification and the production ability that the softening kettle. The tube body should have enough of just degree and strength.Must keep the straight line of the stalk line and cut a degree of the noodles in install and revolve.The material of the tube body uses the low metal alloy steel of Q235 steel and commonness generally. Raised to transmit heat the efficiency, developed the potential of the steam well, lower the steam to eliminate Consume; raised the roller to soften the tube wall temperature of a pot of heating row tube, increase the equipments processing quantity, raise the material to soften the efficiency. Should according to the category and dissimilarity with amount of waters that oil anticipate, draw up to soften the temperature;When the oil anticipates to contain the amount of water low, soften the temperature and should correspond a little higher, whereas, should be a little lower. Anticipate the dissimilarity with amount of water according to the oil, can carry on heat smooth wet or heat to the water. A djust to soften the condition according to the force result. Another important aspect of shaft design is the method of directly connecting one shaft to another. This is accomplished by devices such as rigid and flexible couplings. A coupling is a device for connecting the ends of adjacent shafts. In machine construction, couplings are used to effect a semi permanent connection between adjacent rotating shafts.
