It is crucial for the central feeding system to maintain stability and have continuous feeding capacity under high load operation. Here are some effective methods to achieve this goal.

1、 Equipment selection and configuration

Select high-quality feeding equipment

Choose a vacuum pump or fan with high capacity and high efficiency. For example, the Roots vacuum pump has the characteristics of fast pumping speed and high vacuum degree, which can stably provide power for material transportation under high loads. Within the designed flow and pressure range, stable suction can be ensured to timely suck materials into the conveying pipeline.

For feeders, such as spiral feeders, it is necessary to choose the appropriate shape and size of the spiral blades. Compared to single spiral blades, double spiral blades are more stable in conveying high load materials, effectively preventing material blockage and ensuring continuous feeding.

Reasonably configure buffer silos

It is necessary to set up buffer silos of appropriate size in the system. Buffer silos can balance material flow when there is a brief fluctuation in material supply. For example, when the upstream material supply speed is slightly slow or there is a slight blockage in the conveying process, the material in the buffer bin can continue to be supplied to maintain the continuous feeding capacity of the system. Based on the maximum feeding capacity of the system and possible fluctuations, calculate the appropriate capacity of the buffer silo. It is generally recommended that the capacity of the buffer silo can maintain normal feeding of the system for 10-30 minutes.

2、 Pipeline system optimization

Optimize pipeline layout

When designing pipelines, the number of bends and reducers should be minimized as much as possible. Excessive bends can increase the resistance of material transportation, especially during high load operation, which can easily lead to material accumulation and blockage. Using large curvature elbows instead of right angle elbows can make the material flow more smoothly in the pipeline. At the same time, the slope of the pipeline should be arranged reasonably, and gravity should be used to assist material transportation, reducing the system's dependence on power equipment.

Material selection and maintenance of pipelines

Choose the appropriate pipeline material based on the properties of the material. For materials with strong wear resistance, such as plastic raw materials containing hard particles, wear-resistant steel pipes can be used; For corrosive materials, use corrosion-resistant plastic pipes such as polytetrafluoroethylene pipes. Regularly inspect the wear and corrosion of pipelines, replace damaged parts in a timely manner, ensure the inner diameter and smoothness of pipelines, and maintain stable material conveying capacity.

3、 Automated Control and Monitoring

intelligent control system

Introduce advanced automation control systems to monitor material flow, pressure, and equipment operation status in real-time through sensors. For example, installing flow sensors and pressure sensors on pipelines allows the control system to adjust parameters such as vacuum pump or fan speed, feeder speed, etc. in a timely manner when there are abnormalities in flow or pressure, ensuring the stable operation of the system.

Fault Warning and Maintenance Plan

Establish a fault warning mechanism and set reasonable alarm thresholds based on system operation data. When the system approaches a critical state, an alarm is issued in advance to remind operators to conduct inspections and maintenance. At the same time, based on the characteristics of high load operation and the service life of equipment, a detailed maintenance plan should be developed to regularly maintain and repair key equipment, replace vulnerable parts, and ensure long-term stable operation of the system under high load.
