Description

Detection device for analyzing coal and rock components Technical Field The invention belongs to the technical field of coal and rock component analysis equipment, and particularly relates to a detection device for coal and rock component analysis. Background The analysis of the coal and rock components is an important means for evaluating the properties of coal and guiding the washing, selecting, processing and utilizing of coal. The standard flow generally comprises the steps of crushing a coal sample, mixing the crushed coal sample with resin, pouring and solidifying the mixture to prepare a coal rock polished section (also called a coal brick), finely grinding and polishing the polished section to expose microscopic components of the coal rock, and finally carrying out component identification and quantitative statistics by utilizing an optical microscope or an image analysis system. At present, from sample preparation, solidification, polishing and detection, operators are required to transfer samples among different devices for multiple times, the procedure connection is incoherent, time and labor are consumed, manual operation is difficult to accurately control in the aspects of crushing granularity, resin mixing proportion, pouring quantity, polishing force, time and the like, quality dispersion of polished sheets in different batches and even in the same batch is caused, and accuracy and comparability of follow-up detection data are directly affected. Finally, a large amount of coal dust and resin dust can be generated in the processes of crushing, grinding and polishing, so that the health of operators is endangered, the laboratory environment is polluted, and dust sedimentation can interfere with a detection light path. In the prior art, patent CN120490088A discloses a coal lithology detection device and a method, wherein the device comprises a polishing disc and a polishing disc for polishing and polishing a coal petrography polished section, and a lifting table and a limiting disc are matched for working, so that the automation of polishing and polishing the coal petrography polished section is realized. The arrangement mode effectively improves the grinding and polishing processes of the coal rock polished section, improves the efficiency and ensures the detection effect of the coal rock polished section. However, the improvement still exists in that the first limiting plate and the limiting plate work cooperatively through the limiting plate and the first elastic piece, so that the clamping force of the coal-rock polished section is insufficient, and the coal-rock polished section moves, even falls off and has low safety when being polished. Secondly, the equipment only realizes automation of grinding and polishing, and both pretreatment and post-treatment of the coal-rock polished section are completed manually, so that the detection efficiency is not obviously improved. Third, device stability and integration are to be further optimized. Therefore, a detection device for analyzing the components of the coal and rock, which can realize full-process automation, sealing and standardization and can integrate detection links on line, is urgently needed.
