The Roots blower for sawdust conveying is a pneumatic conveying equipment designed specifically for sawdust materials. Here is a detailed introduction to it:
1、 Working principle
Roots blower belongs to positive displacement blower, and its working principle is to use two blade shaped rotors to compress and transport gas through relative motion in the cylinder. This blower has a simple structure, is easy to manufacture, and can generate continuous and stable airflow, making it very suitable for pneumatic conveying of sawdust.
2、 Characteristics and advantages
1. Adapt to the characteristics of sawdust:
2. Humidity control: The humidity of sawdust has a significant impact on its conveying performance. When designing Roots blowers, their moisture resistance is taken into account to ensure that the sawdust maintains appropriate humidity during transportation.
3. Particle size distribution: Uneven particle size distribution of wood chips may cause blockages in conveying equipment. By adopting appropriate inlet shapes and airflow channel designs, Roots blowers can effectively avoid blockages and improve conveying efficiency.
4. Provide stable airflow: The Roots blower is designed with dual impellers to generate continuous and stable airflow, providing power for the pneumatic conveying of wood chips. This stable airflow helps ensure that wood chips are evenly and smoothly transported in the pipeline.
5. Adjust conveying pressure: According to the specific needs of sawdust conveying, the Roots blower can adjust its operating parameters, such as speed and flow rate, to control the pressure during the conveying process. Appropriate pressure regulation helps ensure that sawdust can smoothly overcome pipeline resistance and achieve the predetermined conveying distance and speed.
6. Reduce energy consumption: The Roots blower can provide sufficient airflow pressure and flow rate at lower energy consumption, thereby reducing the operating cost of the sawdust pneumatic conveying system. This is particularly important for large-scale and long-term wood chip transportation.
3、 Application and Selection
1. Application areas: Roots blowers for pneumatic conveying of sawdust are widely used in wood processing, wood product production, and other fields, achieving automated conveying of sawdust from the raw material area to the processing area.
2. Choose to consider:
Conveying capacity: Determine the required conveying capacity based on production needs, and then choose the appropriate Roots blower model and specifications.
Conveying distance: Consider the specific distance of sawdust conveying to ensure that the Roots blower can provide sufficient airflow pressure and flow to meet the conveying requirements.
Material characteristics: Select a Roots blower with corresponding moisture-proof and anti clogging capabilities based on the humidity, particle size distribution, and other characteristics of wood chips.
Energy consumption and cost: On the premise of meeting transportation requirements, choose Roots blowers with lower energy consumption and reasonable operating costs.
4、 Maintenance and upkeep
To ensure the long-term stable operation of Roots blowers, regular maintenance and upkeep are necessary. This includes checking the fastening, lubrication, belt tension, and pulley misalignment of various parts, as well as regularly replacing lubricating oil and cleaning the oil tank. In addition, attention should be paid to avoiding installing fans in places where people frequently enter or where flammable, explosive, and corrosive gases are easily generated, in order to prevent accidents such as fire and poisoning.
In summary, Roots blowers used for sawdust transportation have the characteristics and advantages of adapting to sawdust characteristics, providing stable airflow, regulating conveying pressure, and reducing energy consumption. When choosing, comprehensive consideration should be given to specific application requirements and material characteristics. At the same time, regular maintenance and upkeep are also key to ensuring the long-term stable operation of Roots blowers.
