Problems solved by technology

[0004] Although the existing LIBS mineral product detection device can meet the basic needs of use, the disadvantages are still very obvious. The main manifestations are: in the process of mineral product detection, most of the traditional devices can only locate the specific position of the product testing, resulting in a single test result that cannot reflect all the characteristics of the product

Abstract

The invention belongs to the field of LIBS detection, and particularly relates to a bulk mineral product LIBS real-time on-line full-element detection device and detection method, the bulk mineral product LIBS real-time on-line full-element detection device comprises a three-dimensional table and a detection device, the three-dimensional table comprises a bottom plate, the left side of the top surface of the bottom plate is fixedly connected with a net plate extended upwards, the right side of the top surface of the bottom plate is connected with a transmission device, a first motor is installed on the side face of the transmission device, a positioning frame is connected to the left side of the transmission device, and a second motor is installed in an inner cavity of the positioning frame. By adopting the design of the three-dimensional table, in the process of detecting mineral products, the rotating laser device can realize rotary detection on the products, and the transmission device can drive the laser device to move left and right, so that the laser device can be adjusted left and right in real time, and the detection range of the products is greatly improved; and the problem that a traditional device is single in mineral product detection position is solved, the mineral product detection accuracy is indirectly improved, and the feasibility of the device is reflected.

Description

technical field [0001] The invention relates to the field of LIBS detection, in particular to a real-time online all-element detection device and detection method for LIBS of bulk mineral products. Background technique [0002] LIBS refers to laser-induced breakdown spectroscopy. It is a laser-based diagnostic technology that has been proven to be effective in measuring the concentration of various components in various media, including gas, liquid, and solid media. The laser-induced breakdown plasma contains electrons and ions as well as neutral particles, and it shows a rich emission spectrum. The detection of various elements can be realized by using laser-induced breakdown spectroscopy. [0003] The current methods for the determination of harmful substances in ores include atomic absorption spectrometry and spectrophotometry, etc., but the actual operation procedures are very complicated and time-consuming, there will be serious matrix interference, lack of sensitivity...
