The Roots blower in cement plants is a widely used equipment in the cement production process. Its main function is to provide a stable gas source for cement production, which is used in the pneumatic conveying, mixing, ventilation and other process links of materials. The following is a detailed introduction to the Roots blower in the cement plant:
1、 Working principle
The Roots blower in the cement plant is a positive displacement blower, which separates the air inlet through the "meshing" of a pair of rotors (with a gap between the rotors but not in contact with each other). The rotor is driven by a pair of synchronous gears and moves in the opposite direction, pushing the inhaled gas from the intake port to the exhaust port without internal compression. When the gas reaches the exhaust port, it is pressurized due to the reflux of high-pressure gas on the exhaust side, thus completing the gas delivery.
2、 Characteristics
1. Simple structure: Roots blower has a simple structure, is easy to manufacture, and is easy to maintain and upkeep.
2. High conveying efficiency: Due to the use of volumetric working principle, Roots blower can maintain a high gas conveying efficiency.
3. Strong adaptability: Roots blower is suitable for gas transportation and pressurization systems in various pressure situations, especially for cement plants and other occasions that require stable gas sources.
4. Low noise: By optimizing the design and adopting noise reduction measures, Roots blowers can maintain a low noise level.
3、 Selection and Configuration
1. Air volume and pressure: Select appropriate air volume and pressure according to the specific process requirements of the cement plant.
2. Material: Choose suitable materials based on the nature of the gas being transported and the working environment, such as cast iron, stainless steel, etc.
3. Lubrication method: Choose the appropriate lubrication method according to the usage conditions and requirements, such as oil lubrication or grease lubrication.
4. Control mode: Select the appropriate control mode based on the degree of automation and control requirements, such as manual control, automatic control, etc.
4、 Maintenance and upkeep
1. Daily inspection: Regularly check the operating status of the fan, including vibration, noise, temperature, etc., to ensure the normal operation of the fan.
2. Lubrication management: Regularly replace or replenish lubricating oil to maintain good lubrication of gears and bearings.
3. Cleaning and maintenance: Regularly clean the fan casing and air inlet to prevent dust and debris from entering the interior of the fan. At the same time, clean and maintain the interior of the fan to extend its service life.
4. Troubleshooting: Once a fault or abnormal phenomenon is found in the fan, it should be immediately stopped for inspection and the cause of the fault should be investigated, and timely handling should be carried out.
5、 Application Cases
Roots blowers are widely used in various process links of cement production lines, such as pneumatic conveying, mixing, ventilation, etc. Specific cases include:
1. Pneumatic conveying: Using the air source provided by a Roots blower, materials such as cement and fly ash are conveyed through pipelines to improve production efficiency.
2. Mixing and Ventilation: In the cement production process, Roots blowers can be used to drive mixing and ventilation equipment, ensuring uniform material mixing and good workshop ventilation.
In summary, the Roots blower in cement plants is one of the indispensable equipment in the cement production process. By reasonable selection, configuration, and maintenance, the stable operation and performance of the fan can be ensured, providing a stable air source guarantee for cement production.
