The difference between double-shaft screw conveyor and single-shaft screw conveyor

2021-03-05 12:53:44 Double-shaft screw loading conveyor, also known as double-shaft screw feeder, is a continuous conveying equipment widely used in metallurgy, building materials, chemical, food and mechanical processing sectors. The double-shaft screw loading conveyor is equipped with a solid spiral in two seamless steel pipes, one of which is left-handed and the other is right-handed. When working, the two spirals rotate through a pair of gears at the shaft extension position. Due to the rotation of the spirals, the material moves axially, so as to achieve the purpose of feeding. The double-shaft screw conveyor is mainly used for feeding powdery materials. It generally works in a horizontal situation and is suitable for feeding under the silo. In order to achieve uniform feeding and adjust the feeding capacity, the drive of this system adopts an electromagnetic speed regulating motor or a frequency converter to conveniently adjust the speed of the feeder so that it can better meet the actual feeding volume requirements. The structural characteristics of the double-shaft screw conveyor: 1. The head and tail bearing seats are outside the shell, and all bearings adopt multi-layer sealed box with sealing technology, and the bearing has a long service life. 2. Compared with other conveying equipment, it has the advantages of small cross-sectional size, good sealing performance, stable and reliable operation, multi-point loading and unloading, safe operation, and simple maintenance. 3. The screw shaft and the hanging bearing, the head and tail shaft are all connected with the embedded tongue, and the installation and disassembly do not require axial movement, and the maintenance is convenient. Long mandrel, less hanging and fewer failure points. 4. The variable diameter structure is adopted to increase the volume of the hoisting bearing and avoid the contact of the hoisting bearing with the material. The life of the hoisting bearing can reach more than two years. 5. Each transmission part adopts the floating connection mode, and the hanging bearing is a universal structure, so that the spiral body, the hanging bearing and the tail part form an integral rotating floating body. Within a certain range, the resistance can be transported and rotated freely to avoid material jam or blockage. . Xinxiang Company is a manufacturer of conveying machinery and equipment products.
