Liquid automatic detection method

Abstract

The invention relates to a liquid automatic detection method, comprising: S1: a processor determines the quartz window to be selected, and the processor judges whether the quartz window on the current installation groove matches, if it matches, proceed to step S3; if not, Then go to step S2; S2: Start the pushing device to remove the quartz window from the installation groove, start the driving part, the driving part drives the bracket to rotate until the quartz window to be selected faces the installation groove, start the pushing device again, and the pushing device pushes the selected The sheet device moves to insert the quartz window sheet into the installation groove; S3: Start the drive device, the drive device drives the diversion water wheel to rotate forward, the diversion device guides the liquid into the liquid storage chamber, when the processor judges that there is liquid in the inspection chamber , start the Raman spectrometer and light trap for detection; S4: When the processor detects that the liquid reaches the detection amount, start the driving device to drive the diversion water wheel to reverse, and the diversion device guides the liquid into the return chamber.

Description

technical field [0001] The invention relates to a liquid automatic detection method. Background technique [0002] Raman spectrometers are commonly used in liquid detection, which analyzes various main components of liquids. When the existing Raman spectrometer is in use, it is necessary to set up a light trap and a test cell correspondingly. The liquid to be tested is installed in the test cell. The Raman spectrometer is set on one side to emit laser light, and the light trap is set on the other side of the test cell. , used to receive the laser in the inspection cell, and then analyze the various main components in the liquid by judging the received laser light. Raman spectrometers and light traps usually need to use quartz windows for liquid and Raman spectrometers and light traps. Separation, the reason for choosing quartz windows is that it can pass through far ultraviolet rays, which is the best of all ultraviolet materials, and can pass through visible light and near...

When the existing Raman spectrometer is in use, it is necessary to set up a light trap and a test cell correspondingly. The liquid to be tested is installed in the test cell. The Raman spectrometer is set on one side to emit laser light, and the light trap is set on the other side of the test cell. , used to receive the laser in the inspection cell, and then analyze the various main components in the liquid by judging the received laser light. Raman spectrometers and light traps usually need to use quartz windows for liquid and Raman spectrometers and light traps. Separation, the reason for choosing quartz windows is that it can pass through far ultraviolet rays, which is the best of all ultraviolet materials, and can pass through visible light and near-infrared spectra. However, quartz windows can be divided into three categories according to their optical properties. For different liquids, different quartz windows need to be selected. In the prior art, the quartz windows are usually replaced manually. The Mann spectrometer, light trap and test cell are separated, and then the film is changed, so the film change is more cumbersome

In addition, when using a Raman spectrometer to test at present, the liquid is manually introduced into the test pool and then tested, but this method is time-consuming and cumbersome to operate
