What is a screw conveyor?
The screw conveyor is a device that uses a tilted spiral plane to move the material. The spiral of the screw conveyor is stretched at a distance to be browsed and is either located in the trough or fully closed in the cylinder. One end of the conveyor screw is put into contact with liquid, semi -solid or granulated cloth. When the spiral turns, it forces the fabric to move along the trough or cylinder. Other names for the facility include Auger conveyor, spiral conveyor and Helix conveyor. In this application it is easy to identify a screw screw or snail, as it normally requires only a trough, while the upper half of the screw is visible. Examples of this kind of application can be seen feeding grain to or from the silo or filling the basket on the back of the agricultural machinery.
Agriculture and industry can also use flexible screw conveyors that require a complete cover, usually a flexible tube. In addition to the most visible element - flexibility - with a flexible screw conveyor ifSew from other types of conveyors in that the screw usually does not contact the walls of the cover. It is also commonly without a cylindrical core and the screw resembles a spring with flattened coils. Flexible screw conveyors allow moving substances between places where a direct pipe will not function, whether around simple obstacles or floors and walls, as well as virtually any direction or at any angle. This also allows you to move the screw conveyor between the extraction or delivery points, similar to the hose.
The screw conveyor can also be known as the Archimedes screw, because the discovery of the principle behind it is sometimes credited to the Greek mathematician Archimedes. Regardless of the actual innovator, the device is used from at least 235 BCE in Egypt to move water for irrigation. The screw in this application is usually wrapped around the cylindrical core and can be placed in the trough or cylinder. The device is usually located at a slight angle to increase the water from one level of the irrigation ditch to the other. This use of screws toPolicy can also be observed in such diverse applications as pumps in wastewater treatment plants and hemopumpy, medical products used to maintain blood circulation during cardiac surgery.
