Pneumatic conveyor working principle
- The working principle of a pneumatic conveyor is to use the action of air flow to transport materials from one place to another. It generates airflow by compressing air or other gases to suspend materials in the airflow, thereby achieving fast and efficient transportation. Specifically, the working principle of a pneumatic conveyor is based on the principle of pneumatic conveying. First, air flow is generated by compressed air or other gases to form a certain air flow speed and pressure. Then, the material is sent into the conveying pipe through the feeding device (such as the feeding hopper). The material will be picked up by the air flow, suspended in the air flow, and transported along the pipe with the push of the air flow. Finally, the materials are discharged to the destination through the discharge port.
- The structure of a pneumatic conveyor mainly includes a feeding device, a pipeline system, an air source device, a separation device, a control system, etc. The feeding device is responsible for feeding materials into the conveying pipeline. Common ones include feeding hoppers, rotary valves, etc. The pipeline system is the main channel for material transportation. The air source device provides the necessary compressed air or other gases. The separation device is used to separate materials and gases. The control system is used for automatic control of the entire process.
- Pneumatic conveyors have the advantages of simple structure, easy operation, large conveying capacity, long conveying distance, and high conveying speed. Therefore, they are widely used in plastics, casting, chemical industry, food processing and other industries.
What is the pressure in a pneumatic conveyor?
- Extremely low pressure
In the pneumatic conveyor pipeline, if the air pressure is relatively low, usually between 0.2-0.5MPa, it belongs to the extremely low pressure category. In this case, the operating effect of the pneumatic conveyor will be greatly affected, such as slow material conveying speed, insufficient flow, and even material jamming, which affects production efficiency. - Low pressure
The low-pressure category refers to the air pressure in the pneumatic conveyor pipeline between 0.5-0.7MPa. Although it is higher than the extremely low pressure, it is still low. Under low pressure conditions, the material conveying speed of the pneumatic conveyor can be accelerated and the flow rate will also increase, but if it exceeds a certain range, its operating effect will still be affected. - Medium pressure
The medium pressure range refers to the air pressure in the pneumatic conveyor pipeline between 0.7-1.0MPa. In this range, the operating effect of the pneumatic conveyor can be fully exerted. The material transportation speed is faster and the flow rate is larger, which is suitable for many production scenarios.
4.High pressure
The high-pressure range refers to the air pressure in the pneumatic conveyor pipeline being above 1.0-1.5MPa. In this case, the material conveying speed of the pneumatic conveyor is very fast and the flow rate is also very large, but too high air pressure can lead to safety problems such as pipeline bursting.
