Anatomy of the development history of screw conveyors
In industrial production, we can't do without the screw conveyor. Today, Xiaobian will take everyone to understand the development history of the screw conveyor.
The development of screw conveyors is divided into two types of development processes: shaft screw conveyors and shaftless screw conveyors. The shaft screw conveyor consists of a screw, a U-shaped trough, a cover plate, an inlet and a discharge port, and a driving device. Generally, there are three types of horizontal type, inclined type and vertical type; and the shaftless conveyor is screw-modified. It is a shaftless spiral, and has a replaceable lining in the U-shaped groove. The structure is simple. The material is output by the feed inlet and then output by the discharge port. The whole transfer process can be carried out in a sealed tank. In general, the screw conveyors we usually refer to refer to screw conveyors with shaft type.
For many materials that are difficult to transport, people have been seeking a reliable delivery method, and the shaftless screw conveyor is a better solution.
From the middle of the 17th century, the use of aerial ropeway to transport bulk materials began. In 1887, the screw conveyor was invented by Archimedes and later improved. It was widely used in industry to transport bulk and solid materials, and then passed a long time. During the development of time, a series of screw conveyors were gradually developed, which made the screw conveyor have a great development.
GX type screw conveyor is an early type of screw conveyor, and it is also the earliest type of production equipment in China. It is mainly used for conveying powdery, granular and small block materials. It is not suitable for conveying easily degradable, viscous agglomerated materials and large pieces of material, because these materials are easy to stick to the spiral and rotate with it, or The phenomenon of blockage occurs at the hanging bearing, which brings great inconvenience to the material conveying process. The advantages of GX screw conveyor are mainly energy saving and significant consumption reduction. The head and tail bearings are moved outside the casing, which has good dustproof sealing, low noise, strong adaptability, convenient operation and maintenance, and position of inlet and outlet. The layout is flexible; the disadvantage is that the power consumption is large, the parts are worn quickly, and the materials are crushed seriously during transportation.
LS type screw conveyor is a new generation of screw conveyor modified on the basis of GX conveyor. The LS type screw conveyor features novel structure, reliable performance, advanced technical indicators, wide application range and remarkable energy saving.
The above is Xiaobian for everyone to introduce the development history of screw conveyors, I hope to help everyone, if you still have something you don't know, please call us, we will be happy to help you!
