Abstract

The invention relates to the technical field of industrial automatic measurement, in particular to a cement raw material quality online laser detection device and method. By the adoption of the device and method, the technical problems that quantitative analysis of cement raw material elements is not accurate and real-time detection can not be achieved currently are solved; online detection of the compound constituents and ratio value of a cement raw material in a delivery pipe in an industrial field can be conducted quickly and accurately in real time, influences caused by flow change of a cement air-powder column to be measured are avoided through the cooperation of a continuous laser device and a pulse laser device, and the accuracy of detection results is improved greatly; power stability of lasers emitted by the pulse laser device is effectively guaranteed through a laser powder feedback stabilizing device. The whole device is ingenious in design, detection results are accurate and reliable, and production quality of cement products can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of industrial automation measurement, in particular to an online laser detection device and method for the quality of cement raw material. Background technique [0002] At present, the quantitative analysis of cement raw material elements in industry mainly adopts the chemical analysis method, namely the national standard method, but the process is complicated, the conditions are harsh and the analysis time is long, so it cannot guide the adjustment of raw material ratio in time; although X-ray fluorescence spectrometry is time-consuming ( ~5 minutes), but the raw material samples need to be pretreated by manual sampling, grinding, and sample pressing, and the measurement room needs to be evacuated, and the measurement environment requires constant temperature and humidity; Online detection, but the detection results are greatly affected by the content of high atomic number elements, the shape and inhomogene...
