Description

Technical Field

[0001] The present invention relates to the field of detection and analysis instruments, and in particular to a multifunctional online detection and analysis instrument and a detection and analysis method. Background Art

[0002] In the prior art, in the detection analyzer, the measurement of refractive index can reflect the total content of dissolved matter, but it has limitations in measuring the content of insoluble active ingredients in the liquid, especially for solutions with multiple components and no correlation between the components; the light absorption measurement method determines the content of the total active ingredients in the liquid by the light absorption rate, but the light absorption rate of different substances varies greatly. It is often used to measure the content of specific components or the total content of solid-liquid mixtures in multi-component solutions. However, the measurement results are greatly affected by the changes in different components due to the different absorption rates, and there are also great limitations in practical applications; and if two instruments based on the same principle are used for simultaneous measurement, there are problems: the instrument cost is high and two instruments are required; the installation is complicated and time-consuming. The cost is high, two installations are required, and more space is occupied, because it is very important to ensure the long-term stable operation of online analytical instruments under appropriate process conditions. In the process, there are not many very suitable locations, so the resources of suitable installation locations are also limited. Different instruments only output their own measurement results, and the corresponding compensation calculation process requires users to calculate in their own control system, which will increase additional costs. In addition, the output result of the instrument is the final calculation result, not the original signal. There are often many compensation calculations in the calculation process, and the output result cannot reflect the real-time situation of the measured medium. The compensation calculation methods of different instruments are quite different, so using the final output result of the instrument to calculate in the control system may lead to large deviations;

[0003] In industrial production, many chemical substances have high reaction risks. If they cannot be detected and analyzed in time, excessively high or low content of a single substance may lead to production safety problems, product quality problems and ecological environment problems. Therefore, in view of the problems in the current prior art, the present invention proposes an improvement on the detector in the prior art. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that instruments based on two principles are concentrated on the product and cannot detect materials online at the same time, as well as the problems of production safety, product quality and ecological environment caused thereby, and propose a multifunctional online detection and analysis instrument; secondly, to facilitate the adjustment and maintenance of the detector when adapting to the detection and analysis of different materials, thereby improving the quality and efficiency of the detection and analysis.

[0005] To achieve the above-mentioned purpose, the present invention proposes a multifunctional online detection analyzer, including a shell installed on a pipeline, a PCB board installed in the shell and a CCD connected to the PCB, a processor, a temperature sensor, and a detector installed on the pipeline for transmitting the detection results to the processor; its characteristics also include a lighting assembly and a lighting adjustment mechanism installed in the shell.

[0006] Furthermore, the total lighting components are reflective lighting mechanisms and transmissive lighting mechanisms.

[0007] Furthermore, the reflective lighting mechanism and the transmissive lighting mechanism both include a light source mounted on a PCB board, a lighting lens and a prism mounted on a housing, and a lighting adjustment mechanism matched with the light source and the lighting lens.

[0008] Furthermore, the lighting adjustment mechanism is divided into a manual adjustment mechanism and an automatic adjustment mechanism.

[0009] Preferably, the manual adjustment mechanism includes a bracket, a lighting lens cover threadedly connected to the bracket, an adjustment slot provided on the lighting lens cover, and an adjustment tool inserted into the adjustment slot.

[0010] Preferably, the automatic adjustment mechanism comprises a micro motor, a transmission gear mounted on the micro motor, and a reduction gear meshing with the transmission gear.

[0011] Preferably, the transmission lighting mechanism further comprises a light guide sleeve mounted on the lighting lens, the light source of the transmission lighting mechanism is a laser emitting tube, and the laser emitting tube is provided with an adjusting gear for adjusting the laser.

[0012] Furthermore, the shell is divided into a lower shell and an end cover, the lower shell and the end cover are provided with bolt connection holes, insulating terminals and sealing rings are provided between the lower shell and the end cover, and the lower shell is also provided with a temperature sensor cavity.

[0013] A detection and analysis method of a multifunctional online detection and analysis instrument, characterized in that it includes the following:

[0014] a) Refraction analysis: The light source passes through the lighting lens, hits the prism, and is reflected by the prism into another lighting lens. The reflected light source signal is collected by the CCD. The CCD transmits the collected light source signal to the processor for analysis. The refractive index is calculated by analyzing the obtained light source signal, and the content of dissolved substances is obtained by calculating the refractive index;

[0015] b) Transmission analysis: The laser emitting tube emits laser light, which is focused by the light guide sleeve. The laser passes through the material in the pipeline through the light-collecting lens and prism and is projected onto the detector. After receiving the signal, the detector detects and analyzes it. The transmittance is obtained by analyzing the light source signal attenuated when the laser passes through the pipeline material, and the content of solid materials in the pipeline is obtained by calculating the absorbance. The content of dissolved substances and solid substances is calculated by calculating the refractive index and absorbance, and the content of other substances is obtained by subtracting the content of dissolved substances and solid substances from the total amount.

[0016] The beneficial effects of the present invention are as follows: by combining the reflective lighting mechanism and the transmissive lighting mechanism together and coordinating with the processor, the problem of simultaneous online detection of two principle instruments is achieved, avoiding production safety problems, product quality problems and ecological environment problems caused by excessively high or low content of a single substance.

[0017] By adjusting the mechanism, the distance between the lighting lens, the light source and the prism can be adjusted to facilitate the detection and analysis of different materials, thereby avoiding the need to adapt to different light requirements of different materials, thereby further improving the quality and efficiency of the detection and analysis.

[0018] The transmission lighting mechanism uses a laser emitting tube to emit the light source, which solves the problem in the prior art that the light source needs to be converted into parallel light through a conversion mechanism, thereby avoiding the problem of inaccurate detection caused by the attenuation of the light source during conversion, thereby reducing the assembly space and production cost of the light source conversion mechanism in the detection analyzer; and the size of the emitted light source can be adjusted through the laser emitting tube to adapt to different types of materials.
