A detection device and method for rapidly detecting metal types in oil

Abstract

The invention provides a detection device and method for fast detecting the metal type in an oil material. The device comprises an exciting component, a transmission element, an incident lens, a grating, a plurality of photoelectric conversion elements and a computer, wherein the exciting component excites a sample to emit a feature spectrum; the feature spectrum is emitted after being transmitted by the transmission element; the grating is arranged in front of the emergent end of the transmission element; the feature spectrum is diffracted into a plurality of monochrome spectrums; the incident lens is arranged between the emergent end of the transmission element and the grating; the plurality of photoelectric conversion elements receive the monochrome spectrums and convert the monochrome spectrums into electric signals; the computer is connected with a photomultiplier, and records and analyzes the electric signals; the incident lens is arranged at a small-angle deflection mechanism; the small-angle deflection mechanism is connected with the computer; the deflection angle is controlled by the computer. The computer is used for recording and controlling the deflection angle, and the automatic recording and fine adjustment are realized; the original recording and manual fine adjustment are replaced; the best signal value of a certain element in an oil sample can be fast detected; the detection efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of metal element detection methods and devices, in particular to a detection device and method for rapidly detecting metal types in oil. Background technique [0002] In the fields of atomic spectroscopy, applied spectroscopy, metrology and detection, it is often necessary to analyze the elements and their contents of samples. Traditional spectral analysis methods include: spectral analysis methods mainly include atomic emission spectrometry, atomic absorption spectrometry, ultraviolet-visible absorption spectrometry, infrared spectrometry, etc. [0003] With the continuous development of science and technology, the use of spectrometers to analyze oil is becoming more and more popular. The existing principle of spectroscopic oil analysis is that the analyzed oil sample is excited in the analysis gap of the excitation chamber, and then the light emitted by the oil sample is transmitted through the optical fi...

AI Technical Summary

Problems solved by technology

Compared with the traditional analysis method, this method achieves accurate measurement and analysis of metal types from oil, but there are still shortcomings: due to the need to detect the strongest signal, the strongest signal needs to be detected by adjusting the angle of the incident lens, and Every rotation needs to record the rotation angle, but the existing incident lens is manually adjusted and needs to be recorded manually, and the adjustment process cannot be quickly adjusted to the angle at which the incident lens can detect the strongest signal. , the detection of the strongest signal can only be achieved after multiple adjustments, which greatly reduces the detection efficiency
