What should be noted when choosing suitable powder pneumatic conveying equipment?
? ? Due to the significant impact of environmental issues on air quality, it has attracted attention from all over the country. Large scale environmental protection supervision operations have begun, especially in the industrial sector, where production must be carried out under certain environmental protection indicators. Production shall be carried out in accordance with relevant laws and regulations. If the circumstances are serious, the country will close the factory. A series of environmental protection measures have brought good development to powder pneumatic conveying equipment. When many industries recognize the importance of powder pneumatic conveying equipment, they also make mistakes. When selecting powder pneumatic conveying equipment, choose the appropriate powder pneumatic conveying equipment based on the distance. Let's take a look at the requirements below.
? ? Powder pneumatic conveying equipment mainly relies on gas power devices such as fans and compressors, while the transportation of liquid materials mainly relies on pumps, their own gravity, and vacuum equipment.
The powder pneumatic conveying equipment mainly has the following characteristics:
1. Long distance centralized or decentralized transportation, supply and transportation of high-pressure or low-pressure containers, powder pneumatic conveying equipment can basically produce and transport in bulk, which is convenient for production management.
2. The powder pneumatic conveying equipment is simple, with a narrow coverage area and low equipment and maintenance costs. In addition, regardless of the transportation volume, automation can be achieved with only a small number of production personnel, resulting in high labor productivity, low labor concentration, and low management costs.
3. Transportation is not affected by weather or surrounding conditions of pipelines, and there is no moisture, foreign matter pollution, or dust scattering. Powder pneumatic conveying equipment is easy to protect the quality and hygiene of products, avoiding a good working environment.
4. Powder pneumatic conveying equipment has a wide range of applications, capable of pneumatic conveying small particles in powder, granular, block, and flake forms, such as cement, flour, granules, resin chips, etc. Powder pneumatic conveying equipment can meet the special requirements of certain materials during transportation distance, such as nitrogen and carbon dioxide protection. The temperature range for conveying products can reach 400 degrees Celsius.
5. According to the requirements for equipment placement in the workshop, the distance of the powder pneumatic conveying equipment route can be arranged freely. This makes the pipeline layout of the factory more reasonable. It can also be transported in places where other powder pneumatic conveying equipment cannot be laid or transported due to air route conditions.
6. The mixing process, grinding process, drying process, heating process, cooling process, dust removal process, etc. can be carried out simultaneously with the transportation process, and the powder pneumatic conveying equipment can also be carried out simultaneously at the transportation terminal.
? ? If the above items can be checked one by one before pneumatic conveying work, it can effectively reduce the abnormal vibration failure rate during equipment operation. If this situation occurs again under normal inspection conditions, the quality of the equipment itself should be checked. Choosing the appropriate powder pneumatic conveying equipment depends on these parameters such as distance.
1. The powder and air must be completely mixed with the feeder. In other words, air must enter from underneath the material. The material is evenly dispersed in the airflow and carried away by the airflow, effectively exerting the effect of the airflow. Pause or promote to prevent blockage and accumulation of substances.
2. The structure of the powder pneumatic conveying equipment should allow air to enter smoothly without excessive disturbance and turbulence, in order to reduce the distance loss of airflow resistance.
3. The powder entering the airflow should match the direction of the airflow as much as possible to avoid reverse distance transportation. In some cases, it is necessary to slow down the material or utilize its impact to rotate the material, in order to reduce the energy consumption of the airflow and push the material.
