AI Technical Summary
Existing online moisture sensors have low detection accuracy and are easily interfered with in the drying cylinder, making it impossible to achieve closed-loop control. This results in poor strength and uniformity of chemical fiber filaments and unstable product quality.
The detection device combines a grinding unit and a near-infrared spectrometer. It prepares fine and uniform powder by grinding the sample and cooling it with liquid nitrogen, and then detects it with a near-infrared spectrometer. The sampling, cooling, grinding and detection are integrated at the bottom of the drying cylinder to achieve automated operation.
It improves detection accuracy, reduces interference, enables real-time and accurate moisture detection, enhances production stability and product quality, and reduces human intervention.
