What are the Working Principles and Advantages of Plastic Vacuum Feeder?

Plastic vacuum feeder is an industrial equipment that realizes automatic conveying of dry granular materials through negative pressure airflow. Its core function is to solve the problems of dust pollution and manual transfer efficiency in open environment.

When the plastic vacuum feeder is started, the vacuum generator creates a negative pressure environment in the sealed pipe. When the external air flows through the material container, the plastic particles are entrained to form a gas-solid mixed flow. The mixed flow enters the separation device through the conveying pipeline. The filter element physically blocks the gas and the material. The particles settle to the storage bin due to gravity. The purified gas is discharged into the atmosphere or recycled. The control system automatically starts and stops the conveying cycle according to the material level signal to form a closed-loop material transfer process.

Why can plastic vacuum feeder achieve dust-free conveying?

Because the synergistic effect of the fully enclosed pipe and high-efficiency filtration system of the plastic vacuum feeder isolates the material from the external environment, the dust is intercepted inside the conveying system, and the suspended particles in the traditional manual feeding process are prevented from escaping.

Plastic vacuum feeder can achieve the effect of reducing unit energy consumption through negative pressure airflow conveying, and reduce power wear compared with mechanical lifting devices. Compressed air consumption is automatically adjusted as the conveying distance changes, avoiding energy waste. In addition, the modular design allows key components to be quickly replaced, and the filter element backwash cleaning mechanism extends the continuous working time. However, mechanical conveying equipment requires the entire line to be shut down for maintenance, which has a high maintenance cost.
