The Roots blower used in flour mills is mainly used for conveying flour and pulse dust removal. Its selection and application are crucial for the production efficiency and product quality of flour mills. The following is a detailed introduction to the Roots blower used in the flour factory:
1、 Working principle
As a type of rotary positive displacement fan, Roots blower consists of core components such as rotor, synchronous gear, body (cylinder and end plate), and bearing seals. Its working principle is that the cylinder and the two side end plates together form an approximately elliptical space, and the two ends of the cylinder are respectively equipped with suction and exhaust ports, which are connected to the suction and exhaust pipes. A pair of rotors that mesh with each other are driven by synchronous gears to rotate in opposite directions. During the rotation process, the meshing of two involute waist shaped (or 8-shaped) rotors isolates the intake and exhaust ports from each other. Gas is pushed from the suction port to the exhaust port without internal compression, thereby achieving the effect of blowing air.
2、 Performance characteristics
1. Wide air volume range: Roots blowers used in flour mills usually have a large air volume range, which can meet the production needs of flour mills of different scales.
2. High boost: Roots blower can provide high boost capacity, ensuring that flour can overcome resistance smoothly during transportation and achieve stable delivery.
3. Smooth operation: Due to the dual rotor structure of the Roots blower and the presence of gaps between the rotors and between the rotors and the machine body, there is no friction or vibration during operation, resulting in low noise.
4. Easy maintenance: The Roots blower has a simple structure and is easy to maintain, which can reduce the maintenance cost of the flour mill.
3、 Application and Selection
1. Flour conveying: Roots blower plays a key role in flour conveying. By controlling the speed and air volume of the fan, stable conveying of flour can be achieved, ensuring the continuous operation of the production line.
2. Pulse dust removal: During the flour production process, a large amount of dust is generated. Roots blower can be used in pulse dust removal systems to generate high-pressure airflow to remove dust from bag filters and maintain a clean production environment.
3. When selecting, the following factors need to be considered:
1. Air volume requirement: Determine the required air volume range based on the production scale and process of the flour mill.
2. Boosting requirements: Determine the required boosting capacity based on factors such as the length, diameter, and density of the conveying pipeline and flour.
3. Motor power: Select the appropriate motor power according to the air volume and boost requirements to ensure the stable operation of the fan.
4. Brand and Quality: Choose well-known brands and reliable quality fan products to reduce failure rates and maintenance costs.
4、 Maintenance and upkeep
To ensure the long-term stable operation of Roots blowers, regular maintenance and upkeep are necessary. Specific tasks include:
1. Regular cleaning: Regularly clean the dust and debris inside the fan to keep the equipment clean.
2. Check lubrication: Regularly check the lubrication condition of the fan and add or replace lubricating oil in a timely manner.
3. Tightening components: Regularly check whether the fasteners of the fan are loose or detached, and tighten them in a timely manner.
4. Performance testing: Regularly test the performance parameters of the fan, such as air volume, boost, motor current, etc., to ensure that they are within the normal range.
In summary, the Roots blower used in flour mills has the advantages of a wide range of air volume, high pressure rise, stable operation, and easy maintenance. When selecting, factors such as air volume requirements, boost requirements, motor power, and brand and quality need to be considered. At the same time, regular maintenance and upkeep are also key to ensuring the long-term stable operation of the fan.
