In the chemical industry, construction and other industries, we often use tubular screw conveyors to transport non-viscous dry powder materials and small granular materials such as cement, fly ash and lime. A factor for enterprises to improve economic efficiency, so how to improve the conveying efficiency of tubular screw conveyor?
1. Material characteristics
When the tubular screw conveyor conveys the viscous material, the material is easy to stick to the spiral blade and the inner wall of the conveyor, which makes the resistance increase during the material conveying process, which directly affects the conveying efficiency. Therefore, when the tubular screw conveyor conveys viscous materials, the conveying efficiency of the shaftless screw is higher than that of the shafted screw.
2. Diameter
Under the same conditions, the conveying efficiency of a conveyor with a larger diameter is higher than that of a smaller diameter.
3. Speed
The rotating speed of the tubular screw conveyor is mainly determined by the power of its motor, and the size of the motor power determines the conveying capacity of the tubular screw conveyor. If the motor power is too small, the running speed of the material in the tube will become slower. , reducing the conveying efficiency, and in severe cases, the motor will be burned. If the power of the motor is too large, the power consumption will increase and the operating cost of the enterprise will increase. Therefore, it is necessary to limit the speed to a certain extent and cannot exceed a certain limit value.
4. Set up suction pipes and vents
Suction pipes and vents can be provided at the head and bottom to ensure that no overflow is formed during the feeding process of the conveying trough of the screw conveyor. The tubular screw conveyor must have reliable cold resistance, so that it can ensure sufficient working efficiency in the cold winter.
5. Placement
Attention should be paid to the placement of the tubular screw conveyor, and a certain distance should be reserved to ensure a certain space for ventilation and maintenance, which is conducive to quickly solving problems and improving work efficiency. Riveting or bonding anti-skid on the surface of the head bearing can effectively ensure the normal operation of the conveyor, improve the friction coefficient, prevent slippage during material transportation, and improve work efficiency.​​
6. Working environment
The workplace of the tubular screw conveyor should be kept clean and ventilated to avoid moisture or leakage, and reduce the damage to the screw conveyor, thereby prolonging the service life and improving the work efficiency of operators.
