In the design of pneumatic conveying of rice, the application of Roots blower and air damper is crucial. The following provides a detailed application guide:
1、 Application of Roots blower in pneumatic conveying of rice
1. Function
Roots blower is the main power equipment of the rice pneumatic conveying system, used to generate sufficient airflow to transport rice along the airflow direction in a closed pipeline.
Through the airflow generated by the Roots blower, rice can be transported continuously and pollution-free from one place to another.
2. Selection
When choosing a Roots blower, it is necessary to consider parameters such as the conveying capacity, conveying distance, conveying height, and number of bends of rice.
According to specific working conditions, such as horizontal conveying distance, conveying height, etc., suitable Roots blower models and specifications can be selected.
It is recommended to choose Roots blowers that are capable, reliable, and have low maintenance costs to ensure the stable operation of the rice pneumatic conveying system.
3. Application examples
In the pneumatic conveying system for rice, Roots blowers are usually used in conjunction with feeding devices, dust removal devices, conveying pipelines, and separation devices.
By adjusting the air volume and pressure parameters of the Roots blower, it is possible to control parameters such as rice conveying speed and conveying volume.
2、 Application of Wind Shutter in Pneumatic Conveying of Rice Grains
1. Function
The air damper plays a key control role in the pneumatic conveying system for rice, used to control the feeding, discharging, and airflow of rice.
By operating the switch of the air conditioner, the transportation process of rice can be controlled to avoid leakage and waste of rice.
2. Selection
When choosing a wind damper, it is necessary to consider parameters such as grain size, density, conveying capacity, and pressure of the conveying system of the rice.
According to specific working conditions, such as the particle size distribution of rice and the pressure of the conveying system, the appropriate model and specification of the air damper can be selected.
It is recommended to choose a damper with a simple structure, easy operation, and good sealing performance to ensure the stable operation of the rice pneumatic conveying system.
3. Application examples
In the pneumatic conveying system for rice, the air damper is usually used in conjunction with Roots blowers, conveying pipelines, and separation devices.
By adjusting the switch time and frequency of the air conditioner, the control of the rice transportation process can be achieved, ensuring that the rice can be transported according to the predetermined route and speed.
3、 Precautions for the design of pneumatic conveying system for rice
1. System layout
The layout of the rice pneumatic conveying system should be reasonable, avoiding excessively long conveying distances and too many bends to reduce airflow loss and rice wear.
2. Pipeline material
The conveying pipeline should be made of wear-resistant and corrosion-resistant materials, such as ceramic pipes, to extend the service life of the pipeline and reduce the pollution of rice.
3. Dust removal device
Dust removal devices should be installed in the pneumatic conveying system for rice to ensure the cleanliness of the rice and the stable operation of the conveying system by removing dust and impurities from the airflow.
4. Measures taken
The rice pneumatic conveying system should be equipped with necessary measures, such as explosion-proof devices, emergency stop buttons, etc., to ensure the operation of the system and the safety of personnel.
In summary, the application of Roots blowers and dampers in the design of rice pneumatic conveying is crucial. By selecting and using Roots blowers and dampers reasonably, it is possible to achieve pollution-free transportation of rice, improve the efficiency and quality of rice processing and storage.
