Coal sample preparation system and method

Abstract

The invention discloses a coal sample preparation system and method. The system comprises control equipment, an intelligent sorting and self-sensing subsystem, a sample integrated treatment subsystem and a sample packaging subsystem, the intelligent sorting and self-sensing subsystem is used for sampling and property detection of coal samples; the control equipment controls the intelligent sorting and self-sensing system to perform sample combination and batch reduction on the collected samples; the sample integrated treatment subsystem performs crushing and division treatment on the coal samples subjected to sample combination and batch reduction to obtain prepared samples and waste materials; the control equipment is also used for coding the sample preparation sample according to the sample information of the sample preparation sample and adjusting the working parameters of the sample integrated processing subsystem according to the weight data of the sample preparation sample; and the sample packaging subsystem is used for packaging the coded sample preparation sample to obtain a packaged sample with a code. According to the invention, the full-automatic process of coal sample preparation can be realized, and the working parameters of the system can be automatically adjusted and optimized.

Description

technical field [0001] The invention relates to the technical field of coal sample preparation, in particular to a coal sample preparation system and method. Background technique [0002] Coal in the production, processing, logistics, use and other related industries need to analyze the moisture, ash, volatile matter, calorific value, sulfur content and other parameters of coal. In order to meet the requirements of coal quality analysis, it is necessary to sample and prepare coal. The current preparation of coal samples in my country still relies on manual operations. According to the national standard GB / T474 "Coal Sample Preparation", the main operations in the coal sample preparation process include sieving, mixing, and shrinking. During the operation, the sample preparation equipment requires personnel to operate and transfer related sample preparation processes. The sample preparation cycle is long, the labor intensity is high, and the dust pollution is large. At the ...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the large differences in the properties of coal samples processed in coal mines, the existing sample preparation systems usually use the same parameters and simple procedures set by the system for processing, and the system efficiency and adaptability are low

[0005] 2. It is difficult to trace the parameters of the intermediate process of the sample. For example, when there is a problem in the sample preparation process, it is difficult to confirm whether it is due to the system itself or the influence of the nature of the incoming material. It is difficult to optimize the sample preparation process
