Integrated sampling method used for coal sample detection and integrated sampling system

Abstract

The invention relates to an integrated sampling method used for coal sample detection and an integrated sampling system. The method comprises the following steps: S1) sampling; sampling is carried out in stacking or transport equipment; S2) viscosity determination; by determining the viscosity of the coal sample, whether an automatic sampling and sample production link is introduced or not is selected; if the viscosity requirement cannot be satisfied, drying is carried out, and then the coal sample is sent to automation sampling and sample production equipment, or is directly output for artificial sampling and sample production; and S3) sampling and sample production; through viscosity determination of the coal sample in the step 2), if the requirement is satisfied, the sampling and sample production are automatically carried out. The system is used for carrying out the above method. The system has the advantages of principle and simple operation, and the reliability of the automation work and flow process smooth degree can be greatly increased.

Description

technical field [0001] The invention mainly relates to the technical field of coal quality analysis, in particular to an integrated mining method suitable for coal sample detection and an integrated mining system. Background technique [0002] The analysis of coal quality is actually a process of sampling analysis. Coal is an inhomogeneous substance (grain size, distribution of quality characteristics, etc.), and the sampled parent stock is generally relatively large (ranging from tens of tons to tens of thousands of tons), so as to maximize the sample that can represent the quality and characteristics of the entire stock sample The process of a representative sample is called "sampling". At present, there are various methods such as mechanical sampling, manual sampling, and semi-mechanical sampling. Each country has mandatory standards, and sampling work must be carried out in accordance with the standards. After the sample is collected according to the standard, the nex...

Problems solved by technology

However, due to the strong subjectivity of artificial recognition, there are often phenomena such as missed judgments and misjudgments.

Therefore, before the coal enters the sampling system, a special person is required to be on duty and make judgments. The coal that cannot be processed by the automatic sampling equipment must be manually separated by workers, which results in its high labor intensity, long cycle time, and poor accuracy.
