The screw conveyor is mainly composed of screw, shell, support and screw shaft.
a) solid spiral b) endless spiral c) blade spiral d) forming spiral
1-spiral shaft 2-spiral blade
The spiral blade is made of a thin steel plate with a thickness of 4 to 8 mm or stainless steel, brass, aluminum or other materials. When transporting highly corrosive materials, the surface of the blade is covered with a layer of tungsten, chromium, cobalt and other hard alloys or other similar anticorrosive materials.
The mandrel-free spiral is also called a coil spring, as shown in Figure 1-15. The spiral spring has a simple structure, is easy to process and assemble, and has a lighter weight than the mandrel-type spiral, which can be less than 90. Turn at any angle. This kind of screw is suitable for conveying powder materials, which has a large crushing force on granular materials and a small conveying capacity.
a) Rectangular cross-section spiral b) Mesh-shaped cross-section spiral c)
Conveyors with equal pitch are mainly used for conveying materials; variable-pitch conveyors can produce squeezing and chucking at the same time as conveying, such as feeding and squeezing in meat grinders, juicers, puffing machines and other machinery For spiral.
The function of the spiral shaft is to fix the spiral blades and drive the blades to rotate together. The spiral shaft can be a solid shaft or a hollow shaft. Hollow shafts usually made of steel pipes are generally assembled from 2 to 4 m long segments.
The connection of each section of the spiral shaft is usually a shaft connection or a flange connection. Figure 1-16 is to insert the shaft section into the hollow shaft =} inch sleeve and fix it with screws.
These shaft joints can also be used as the neck of the intermediate bearing and the head bearing. This connection method has a compact structure, but it is more difficult to disarm. Large screw conveyors are connected by flanges, and a section of short shafts with flanges at both ends is connected to the flange at the end of the screw shaft. This connection is easy to load and unload, but the radial direction t and r are larger, and the resistance to the material is also greater.
