Basic components of pneumatic conveying system
The basic components of pneumatic conveying system:
1. Gas source (Roots blower/air compressor)
Roots blower is generally used as the gas source for dilute phase pneumatic conveying, with positive pressure blowing or negative pressure suction
2. Conveyor device
Rotating feeder: This equipment is a commonly used conveying device in pneumatic conveying systems, commonly found in dilute phase pneumatic conveying systems. The rotating feeder can uniformly and continuously convey materials, and has the characteristics of wear resistance, no backflow, no material return, high sealing performance, and easy maintenance in the later stage;
Warehouse pump: Warehouse pump is a commonly used conveying equipment for dense phase pneumatic conveying, suitable for conveying powder materials. The conveying process is fully sealed, dust-free, and can be transported over long distances. It has a large conveying capacity, long service life, and easy maintenance. It is widely used in power plants, ash yards, etc
3. Dust removal equipment:
Whether it is positive pressure conveying or negative pressure conveying, the material gas separator is an essential equipment.
4. Control system
The pneumatic conveying system can be equipped with manual control and automatic control. In addition to using local control, we can also add centralized control to make it more convenient and easy for workers to monitor and observe the use of the conveying system. The pneumatic conveying system is equipped with complete detection signal devices, which can be observed through the PLC centralized control system to generally grasp the safety status of the conveying system at any time.
