Embodiment Construction
[0028] The coal product ash automatic detection method of the present invention is to use a high-precision belt scale and a volume scanner to measure the quality and volume of the coal product in real time during the coal belt transportation process, calculate the product density by a computer, and input the product density into the computer at the same time The density-ash relationship curve of coal products, the density-ash relationship curve of coal products is calculated through the data of the floating and sinking test, and the computer automatically calculates the product ash according to the product density and the product density-ash relationship curve.
[0029] The specific steps of the above method are as follows:
[0030] (1) Install a high-precision belt scale on the product transport belt to detect the product quality m, install a volume scanner at the corresponding position to accurately measure the volume V of the material being weighed, and the high-precision be...

The invention discloses an automatic detection method for the coal product ash content and belongs to the technical field of coal dressing detection methods. The automatic detection method is used for performing on-line ash content detection on a coal product. According to the technical scheme, in the process of conveying coal through a belt, a high-precision belt weigher and a volume scanner are used for determining the quality and volume of the coal product in real time; the density of the product is calculated through a computer, a density-ash content relation curve of the coal product is input into the computer, and then the computer automatically calculates the ash content of the product according to the density and the density-ash content relation curve of the product. The method is a brand-new detection method for the coal product ash content and is an innovation in the field of coal detection, on-line real-time detection of the coal ash content is achieved, the simple, rapid and accurate on-line detection method for the ash content is provided for the coal product, can achieve continuous and rapid detection on a coal conveying line, quite facilitates guiding of the production process in time and improves product quality through continuous detection and has remarkable economic benefits.
Description
technical field [0001] The invention relates to a coal product ash detection method, which belongs to the technical field of coal preparation detection methods. Background technique [0002] Ash content is one of the important indicators of coal product quality, but the determination of coal ash content is mostly carried out in the laboratory. The measurement of ash content generally adopts three steps of sampling-sample preparation-ash burning, and it takes 1 hour at the fastest. For the continuous production process, this detection method has a certain hysteresis and discontinuity, and cannot guide the production process in time. At present, most coal products are raw coal, clean coal, middling coal and gangue, and ash content is equally important to these four products. When purchasing raw coal, it is difficult to measure whether the ash content of raw coal products is continuous and stable; clean coal products are the most important products after coal washing, and ash ...
