AI Technical Summary
In existing technologies, the methods for detecting major elements such as phosphorus, sulfur, and fluorine compounds in chemical production are complicated, time-consuming, and have a low degree of automation. Furthermore, the traditional installation structure is not easy to adjust, which affects the accuracy of the detection results.
Design an online monitoring device, including a support frame and a near-infrared online monitoring analyzer. The support frame consists of support legs, a base, and a light-shielding curtain. The support frame is height-adjustable. The near-infrared online monitoring analyzer is mounted on the base. The light-shielding curtain is used to avoid interference from external light sources and ensure detection accuracy.
It enables convenient installation and height adjustment of the near-infrared online monitoring and analysis instrument, reduces interference from external light sources, improves the accuracy and automation of detection results, and reduces operational complexity and cost.
