本装置发明的目的是提供一种新颖的螺旋输送机,它能高效率地作长距离垂直提升固体流料。其基本原理为:用一管状筒体,一端设有入口,另一端为出口。筒体内装有一轴,既可旋转又可作轴向运动,轴上装螺旋叶片,筒体内壁上也装有与轴上螺旋相反旋向的螺旋叶片。两组叶片各以一些狭小间隙在径向位置断开,当轴与筒体相对转动时,这些间隙能让叶片在重叠情况下相互通过。其结果,轴相对于筒体转动时使装在轴上的叶片相对于装在筒体壁上的叶片交替地升起和下落,而轴每垂直运动一次使流料向上移动一定的距离。装置结构图参见图1。在下部有平口倒
The purpose of the invention of the device is to provide a novel screw conveyor which can efficiently lift the solid flow material vertically over long distances. The basic principle is: using a tubular body, one end is provided with an inlet and the other end is an outlet. The cylinder body is equipped with a shaft, which can rotate and move axially. The shaft is equipped with a spiral blade. The internal wall of the cylinder is also equipped with a spiral blade which rotates in an opposite direction to the spiral on the shaft. The two groups of blades are each separated at a radial position by narrow gaps. When the shaft and the cylinder rotate relative to each other, these gaps allow the blades to pass through each other in an overlapping manner. As a result, when the shaft rotates relative to the barrel, the vanes mounted on the shaft alternately rise and fall relative to the vanes mounted on the barrel wall, and each vertical movement of the shaft causes the flow material to move upward by a certain distance. See Figure 1 for the device structure. There is a flat mouth down in the lower part
