Embodiment Construction
[0025] Such as figure 1 Shown, a kind of inspection method after separating exinite from coal, it is characterized in that comprising the following process step that carries out in order:
[0026] (A) The inspection has been completely separated: the exinite is separated from the coal by the heavy liquid floating sinking method or the heavy liquid centrifugation method, and after obtaining the floating object containing the exinite floating on the upper part of the heavy liquid solution, the floating object containing the exinite is separated. Put the material into a quartz glass layered tank with heavy liquid, stir to obtain a mixed solution containing exinites, let it stand for 3-5 minutes, and then turn on the exinite fluorescent lamp of the inspection device, using a wavelength of 320-400nm The UVA ultraviolet light irradiates the quartz glass layered tank. When irradiating, it should be irradiated from the side of the quartz glass layered tank and from top to bottom, and ...

Abstract
The invention discloses a detection method for exinite separated from coal and a detection device thereof. The detection method for exinite separated from coal comprises the following steps in sequence: (A) detecting whether the exinite is thoroughly separated; (B) detecting the concentration of the separated exinite. The detection device used by the detection method comprises an exinite fluorescent lamp and a light sensing and detecting device, wherein the exinite fluorescent lamp comprises a base I, a gear movable joint, an adjusting rod, a UVA waveband ultraviolet light source and a power socket; the light sensing and detecting device comprises a base II, a telescopic rod and a silicon photocell light meter. The detection method for the exinite separated from the coal is simple and practical, and is capable of quickly detecting whether the exinite can be thoroughly separated and accurately indicating the height of the separated exinite in a quartz glass layering tank and the concentration of the separated exinite; the detection device used for the detection method is simple in structure, convenient to use, and intuitive, accurate and quick in detection.
Description
technical field [0001] The invention designs an inspection method and an inspection device after exinite is separated from coal. Background technique [0002] Due to the different coal-forming materials and their coal-forming geological conditions, coal formed three organic microcomponents during the formation process: vitrinite, inertinite and exinite. The relative content and properties of different organic microcomponents determine the properties and thermochemical characteristics of the coal species. Therefore, by studying the content of each organic microcomponent in the coal sample, the properties and thermochemical characteristics of the coal can be known, and different organic microcomponents have different uses. For example, among the above three organic microscopic components, the exinite is mainly composed of reproductive organs, protective tissues and their secreted metabolites, bacteria and algae, microbial degradation products and other substances of higher pl...
