Abstract
The utility model discloses a melt composition real-time on-line detecting device belonging to the range of testing devices. The utility model comprises two sections formed by the connection of the fiber optic: a data acquisition analysis system comprising a computer, a spectrometer, a pulse generator and a controller, and a laser induction decomposing light spectrum probe comprising a laser generator placed according to a light path and a front tuning analyzer and an optical leakage, and a convex glass, a dichroic mirror and a light guide fiber placed successively from bottom to top according to the length of the focal distance. Each element in the melt of the utility model transmits optical signals produced by the direct excitation of the laser into the data acquisition analysis system, tests the real-time content of the composition, figures out the composition, and adjusts the addition. As a result, the melt composition real-time on-line detecting device realizes the real-time on-line detecting of the melt composition, greatly shortens the assay determination time of the melt composition, improves the quality of products, increases the deliverability, lowers the energy consumption, correspondingly extends the battery life, and provides conditions for the continuous or semicontinuous smelting production.
Description
Technical field
The utility model belongs to the checkout equipment scope, particularly a kind of bath component real-time online determinator.
Background technology
At present, to the method for bath component determination and analysis, all be by in melt, obtaining sample, analyzing via laboratory testing equipment again according to certain method, to analyze data again and turn back to flushing and casting person, the operator carries out according to measurement result that melting adjusts again.This mensuration cycle generally needed 3-10 minute and even the longer time, and at this moment the melt in the body of heater can only be waited for.The measurement result that will cause energy loss like this and cause because of component scaling loss in the stove is unfounded, and then influences product quality.Along with the continuous aggravation of global energy crisis and the people expectation to high quality of products, developing a kind of bath component, to implement the real-time online determinator extremely urgent.The bath component real-time online determination techniques of our company's research and development and the application and the popularization of device will be to the raisings of China's melting usefulness, the reduction of cost, and the lifting of quality produces important and far-reaching influence.
Summary of the invention
The purpose of this utility model provides a kind of bath component real-time online determinator that utilizes laser induced decomposed spectrum technology.It is characterized in that: described bath component real-time online determinator is made up of two parts: a part is a data acquisition and analysis system; A part is laser induced decomposed spectrum probe (being called for short the LIBS probe).Described data acquisition and analysis system comprise computing machine 1, spectrometer 2, pulse producer 5 and with its controller that is connected respectively 3; Spectrometer 2 is connected with reinforcement array diode detector 4 again; Strengthening array diode detector 4 is connected with the light transmitting fiber 8 of laser induced decomposed spectrum probe; Described laser induced decomposed spectrum probe comprises the laser generator of putting according to light path 6, and the tuning separation vessel 7 of front and light leakage 15; Convex lens 12, dichroic mirror 11, middle convex lens 10, last convex lens 9 and the light transmitting fiber 8 from bottom to top placed successively according to focal length length constitute, and the output of pulse producer 5 is connected with laser generator 6.

Embodiment
The utility model provides a kind of bath component real-time online determinator that utilizes laser induced decomposed spectrum technology.At Fig. 1. shown in the bath component real-time online determinator synoptic diagram, this device is made up of two parts: a part is a data acquisition and analysis system; A part is laser induced decomposed spectrum probe (being called for short the LIBS probe).Described data acquisition and analysis system comprises respectively and computing machine 1, spectrometer 2 and pulse producer 5; Spectrometer 2 is connected with reinforcement array diode detector 4 again; Strengthening array diode detector 4 is connected with the light transmitting fiber 8 of laser induced decomposed spectrum probe; Described laser induced decomposed spectrum probe comprises the laser generator of putting according to light path 6, and tuning separation vessel 7 in front and light leakage 15; The following convex lens of on melting container 14, placing successively from the bottom to top 12, dichroic mirror 11, middle convex lens 10, on convex lens 9 and light transmitting fiber 8 constitute, the output of pulse producer 5 is connected with laser generator 6.
The effect of LIBS probe is that each component characteristics spectral line in the melt is ejected, and the effect of data acquisition and analysis system is the intensity according to each component characteristics spectral line, and each components contents is calculated.According to the situation of different stoves, select to have the representational zone of component, with the following 5-10 centimeters of LIBS probe vertical insertion molten surface, and be fixed in the body of heater top.Data acquisition and analysis system is chosen in body of heater and closes on and have stabilized power source, and the ground amplitude is little, temperature stabilization, and relative humidity is not more than 60% environment and installs.According to the melting requirement, computer real-time is sent instruction to the LIBS probe, and LIBS probe action taking-up light signal is sent to the real-time computing of data acquisition and analysis system and becomes percentage composition output, and calculates component adjustment addition.
