System Components and Working Principle

The pneumatic conveying system for electrode powders typically consists of several key components, including a material hopper, a rotary airlock valve, a conveying pipeline, a dust collection unit, and a discharge hopper. The working principle involves the use of compressed air to create a flow that transports the powder from the source to the destination. When the material is introduced into the hopper, it is fed into the conveying line through the rotary airlock valve, which controls the flow rate and prevents backflow. The compressed air, often supplied by an air compressor, creates a pressure differential that propels the powder particles through the pipeline. The system may employ different conveying modes, such as dilute-phase or dense-phase, depending on the material characteristics and the required transport distance. In dilute-phase conveying, the powder is suspended in the air stream, while in dense-phase conveying, the powder is transported in a more compact form, reducing the risk of particle degradation.

Operation Process of the System

The operation process of the pneumatic conveying system for positive and negative electrode powders begins with the loading of the powder material into the hopper. The rotary airlock valve then regulates the feed rate, ensuring a consistent flow of powder into the conveying line. Compressed air is introduced at the inlet of the pipeline, creating a high-velocity airflow that entrains the powder particles. As the mixture travels through the pipeline, it reaches the discharge hopper at the receiving end. The air and powder are separated in the dust collector, where the air is filtered and the powder is collected for further processing. This process is automated and can be controlled via a programmable logic controller (PLC), allowing for precise control over the conveying parameters such as air pressure, flow rate, and material feed rate. The system also includes safety features like pressure relief valves and overfill protection to ensure safe operation and prevent equipment damage.

Advantages and Applications

The pneumatic conveying system offers several advantages over traditional methods like bucket elevators or belt conveyors. It provides a dust-free and enclosed environment, reducing the risk of material contamination and improving workplace safety. The system also minimizes material degradation due to reduced friction and impact during transportation. Additionally, it can handle a wide range of powder characteristics, including different particle sizes, densities, and moisture contents. In the battery manufacturing industry, this system is widely used for transporting active materials like lithium cobalt oxide (LCO), lithium iron phosphate (LFP), and other electrode powders, ensuring that the materials are delivered to the next production stage in a clean and efficient manner. The system's ability to maintain the integrity of the powder particles is critical for achieving high battery performance, as any contamination or degradation can significantly affect the battery's energy density and cycle life.
