AI Technical Summary

Technical Problem

In existing technologies, there is a time lag between the collection of liquid media into the container and the detection, making it impossible to update measurement data in real time. Furthermore, impurities in the measurement medium can easily contaminate the probe, leading to reduced measurement accuracy and sensitivity, increased cleaning and maintenance work and labor, and making it difficult to meet the real-time and accuracy requirements of coal chemical production.

Method used

A simple liquid medium sampling device was designed, including a flow cell, a measuring chamber, an overflow port, and a filter screen. The measuring chamber is set inside the flow cell to stabilize the flow, the overflow port regulates the liquid level, and the filter screen intercepts impurities to ensure the stability and accuracy of the probe measurement environment.

Benefits of technology

It achieves real-time and accurate measurement, reduces manual operation, lowers labor intensity, extends probe life, and meets the on-site sampling and measurement needs of coal chemical production.
