In modern industrial production, due to its efficient and flexible characteristics, airflow conveying technology has been widely used in the transportation of various materials. Airflow transportation not only solves the problems that traditional transportation methods cannot handle, but also greatly improves production efficiency and environmental protection. This article will introduce several airflow conveying processes that are helpful for understanding the characteristics and applicable scenarios of different airflow conveying schemes.

1. Dilute phase pneumatic conveying

Dilute phase pneumatic conveying is a technology that utilizes lower density airflow to transport materials in a point to surface manner. The process mainly includes the following:

Airflow generation: The airflow entering the conveying pipe is generated by a fan or air pump.

Material introduction: Powdered materials enter the pipeline through a hopper or feeding port, and mixed airflow enters the pipeline.

Material transportation: Air flow pushes materials towards the destination, forming a sparse mixture state.

Material separation: at the conveying terminal, through a separation device(such as a cyclone separator) separates the airflow from the material and collects the material at the target location, thereby achieving material separation.

Advantages: Dilute phase pneumatic conveying is suitable for processing materials with small particles and good flowability, such as fertilizers and plastic particles. Its advantages are fast transmission speed, long distance, and effective prevention of material agglomeration and blockage.

2. Dense phase pneumatic conveying

Dense phase pneumatic conveying is suitable for materials with poor fluidity and high dust content, using high-density airflow to process powdery materials. The process mainly includes the following:

Airflow generation: High density airflow is created using high-pressure fans or air pumps.

Material conveying: The material is fed into a high-density airflow and pushed towards the destination by the airflow through a feeding device.

Separation and collection: At the transfer terminal, the airflow and materials are separated by a separation device, and the materials are collected into a storage container.

Advantages: The dense phase pneumatic conveying system can efficiently process large particles, high-density materials such as cement and ore. Its characteristics are high stability and strong adaptability, especially suitable for situations where materials need to be protected from moisture and use in high temperature environments.

3. Transport of mixed airflow of dilute and dense phases

The mixed airflow transportation of dilute and dense phases combines the advantages of dilute and dense phase airflow transportation, and is suitable for situations that require flexible adjustment of airflow state. In different environments, the process mainly includes the following:

Airflow regulation: The system can adjust the airflow density according to the type of material and conveying requirements. Make the system run more efficiently and meet various requirements of materials during transportation.

Material handling: After airflow regulation, the material is effectively transported to the target location. Enable the processing process to proceed smoothly. Improve the processing effect.

Separation and Collection: In order to ensure accurate collection and storage of materials during the conveying process, a separation device is used at the conveying terminal to separate the airflow and materials. Ensure that the airflow and materials do not affect each other during the conveying process, thereby achieving precise collection.

Advantages: The advantage of this airflow conveying method lies in its high flexibility and adaptability, which can process various materials of different properties and adjust the airflow density according to actual needs to meet various production needs. Therefore, it has good applicability.

4. Negative pressure airflow delivery

The main process is as followsIn order to create a negative pressure environment for the smooth passage of powder materials during transportation, it is first necessary to crush the powder materials to be transported.

Negative pressure generation: Use negative pressure fans or vacuum pumps in the conveying pipeline to create a negative pressure environment inside the pipeline.

物料引入The material is introduced into the negative pressure pipeline through the feeding device.

Transportation process: In a negative pressure environment, the material is attracted by the airflow and transported to the destination.

Material separation: After passing through the separation device at the conveying terminal, the airflow and material are collected separately to achieve precise extraction of the required material.

Advantages: Due to its suitability for handling high dust and easily agglomerated materials such as coal powder and ores, negative pressure airflow transportation has these advantages. It can reduce dust leakage, improve the accuracy of material transportation, and operate effectively in high dust environments.

5. Positive pressure airflow delivery

Positive pressure airflow conveying is a method of conveying materials by utilizing an environment that generates positive pressure. The main process is roughly as followsDue to the device that generates positive pressure requiring certain control and regulation of the material, the material is transported through a pipeline with positive pressure airflow at a certain flow rate.

Positive pressure generation: Using a positive pressure fan or compressor in the conveying pipeline to generate a positive pressure environment.

Material conveying: Airflow pushes materials towards the target location under positive pressure environment.

Separation and Collection: At the transmission terminal, the airflow and materials are separated by a separation device to ensure the collection of materials.

Advantages: The positive pressure airflow conveying system is suitable for processing large quantities of materials with good fluidity, such as cement and plastic particles. The advantages are fast transmission speed, high efficiency, and the ability to maintain a stable state even over long transmission distances.

It can meet the transportation needs of various powdered materials, and different airflow transportation processes have their own characteristics. Dilute phase pneumatic conveying, dense phase pneumatic conveying, mixed dilute phase and dense phase airflow conveying, negative pressure airflow conveying, positive pressure airflow conveying, each provide efficient solutions for different material characteristics and production requirements.
