Working principle and application of powder pneumatic conveying pump
Powder pneumatic conveying pump is a widely used conveying equipment in the industrial field. The following is related information on its working principle and application:
1、 Working principle
The powder pneumatic conveying pump uses gas to push the powder for conveying, and its working principle can be divided into two stages:
1. Push stage: The pump body is filled with high-pressure gas, which absorbs the material through the bottom opening of the pump body. The material is pushed into the pipeline, forming a dense particle flow.
2. Transport stage: The pushed particle flow is transported in a fluid like manner within the pipeline, forming a uniformly dense particle flow. By adjusting parameters such as gas pressure and pipeline resistance, different materials can be transported.
3. Specifically, the powder pneumatic conveying pump utilizes airflow to transport granular materials along the direction of the airflow in a closed pipeline. After mixing dust and gas, they move in the conveying pipe. When the lift of the airflow carrying dust is equal to the gravity of the dust, the dust remains suspended. During the conveying process, the conveying speed should be much higher than the suspension speed of the dust to ensure that the material can be effectively conveyed.
2、 Application
Powder pneumatic conveying pumps have the advantages of long conveying distance, high conveying efficiency, and energy saving, and are therefore widely used in multiple industrial fields, including:
1. Cement industry: used for transporting materials such as cement and slag powder.
2. Chemical industry: transportation of materials such as coatings, pigments, rubber, plastics, etc.
3. Thermal power plant: used for transporting materials such as coal powder and ash.
4. Grain processing and oil processing industry: used for transporting materials such as grains and corn starch.
5. Other industries: powder material conveying in industries such as papermaking and food processing.
In addition, powder pneumatic conveying pumps are often used to transport high concentration and high viscosity powders, such as coal powder, cement, etc. During the transportation process, physical or chemical operations such as heating, cooling, drying, and airflow classification of materials can also be carried out simultaneously.
3、 Characteristics and advantages
1. Simple structure: The structure of the powder pneumatic conveying pump is relatively simple, easy to operate, and easy to maintain and upkeep.
2. Stable conveying: Adopting continuous conveying method, the conveying process is stable and reliable, and not easily blocked.
3. Energy saving: The gas pressure inside the pump can be adjusted to achieve energy saving. At the same time, fully sealed and pollution-free transportation meets the requirements.
4. Flexible arrangement: Depending on the specific situation of the system, it can be arranged into single pump single tube or multi pump common tube, multi pump common gas source and other types. Pipelines can be arranged horizontally, vertically, and diagonally to meet the ever-changing layout requirements of engineering.
5. Economically reasonable: Low cost, low system operating expenses, and high economic viability.
In summary, powder pneumatic conveying pumps play an important role in the industrial field due to their working principle and wide application areas. At the same time, its simple structure, stable transportation, energy saving, flexible layout, and economic rationality also give it significant advantages in market competition.
