Description

Technical Field

[0001] The present application relates to the technical field of coal quality analysis and detection, and in particular to a coal quality analysis device with integrated weighing and detection. Background Art

[0002] Coal quality analysis is a series of tests and analysis methods to evaluate the properties and quality of coal. The purpose of coal quality analysis is to determine the composition, properties and combustion characteristics of coal, which include coal quality, composition, calorific value, ash content, sulfur content, moisture content, volatile content, fixed carbon content, etc. At present, laser coal quality analysis technology is a new generation of coal analysis technology, which uses laser to analyze coal samples. Laser coal quality analyzer is a device that uses laser spectroscopy technology to quickly analyze coal quality. Laser coal quality analyzer mainly uses laser spectroscopy technology to scan coal samples. By detecting the spectral characteristics of laser scattering, absorption and emission in coal samples, the analyzer can analyze the composition, structure and properties of coal quality, such as sulfur, ash, volatile matter, calorific value, moisture and the content of multiple elements. The analysis index is highly accurate, so as to obtain the corresponding coal quality index and quality evaluation. There is no need for complex coal sample processing, and the granular coal sample is directly tested. There are some problems with the existing laser coal quality analysis equipment when performing quality inspection. First, it needs to take a part of the coal as a sample and place this sample at the detection end of the analyzer for detection. However, before testing, the sample needs to be weighed. At present, the sample weighing and analytical testing in coal quality testing are two separate steps, which reduces the overall work efficiency. In addition, the existing equipment cannot determine the exact distance between the test sample and the analyzer, which makes it impossible to perform multiple measurements to obtain more comprehensive data, so that the coal quality test results may have certain data deviations.
