Structure and Components of the Pneumatic Conveying System

The resin pellet pneumatic conveying equipment comprises several key components that work in concert to achieve effective material transport. These components include a hopper for material storage, a rotary valve or feeder to regulate the flow of resin pellets, a pipeline system for conveying the material, and a dust collector or filter to manage air and particulate matter. The hopper is designed to hold a sufficient quantity of resin pellets, ensuring a continuous supply to the feeder. It is equipped with a level indicator to monitor the material level, ensuring timely refilling. The rotary valve or feeder controls the discharge rate, preventing overloading and maintaining consistent flow. It may include a material flow sensor to detect blockages or irregularities, triggering an alarm or automatic shutdown to prevent equipment damage. The pipeline system, typically made of stainless steel or other corrosion-resistant materials, is configured to handle the specific characteristics of resin pellets, such as size, density, and moisture content. The system may feature bends and elbows designed to minimize pressure loss and maintain consistent air flow. The dust collector or filter is integrated to capture airborne particles, ensuring compliance with environmental regulations and maintaining a clean working environment. It may use baghouse technology or cartridge filters, with a cleaning mechanism to maintain efficiency over time.

Working Principle of the Pneumatic Conveying System

The operation of the resin pellet pneumatic conveying equipment is based on the principle of pneumatic transport, where air serves as the medium to move resin pellets through the pipeline. The system can be classified into two main types: dilute phase and dense phase conveying, each with distinct characteristics and applications. In dilute phase conveying, resin pellets are suspended in a stream of air and transported at relatively high velocities, typically in a vertical or inclined pipeline. This method is suitable for short to medium distances (up to several hundred meters) and for materials less prone to degradation, such as low-density resin pellets. The air velocity is maintained at a level that keeps the pellets in suspension, preventing them from settling or clogging the pipeline. In dense phase conveying, resin pellets are conveyed in a more concentrated form with lower air velocities, often using a positive displacement blower or compressor. This method is ideal for longer distances (up to several kilometers) and for materials requiring gentler handling to prevent breakage or contamination, such as high-density or abrasive resin pellets. The air velocity is lower, allowing the pellets to move in a more controlled manner, reducing the risk of damage.
