Abstract

The invention discloses an online sample preparing and testing system, which comprises a sampling unit, an analysis sample splitting device, an all water sample splitting device, and an online all water testing system. The analysis sample splitting device is used to process a common coal sample prepared by the sampling unit so as to obtain an analysis sample and is provided with a first outlet fordischarging residual coal sample. The all water sample splitting device is connected to the first outlet and is used to prepare an all water sample from the residual coal sample. The online all watertesting system is connected to a second outlet for discharging the all water sample and is used to measure the water content of the all water sample. The provided online sample preparing and testingsystem separates the all water sample and the analysis sample through two splitting devices; on the basis, the online all water testing system directly measures the water content of the all water sample, the time between the all water sample preparation and test is reduced, the water loss of the all water sample is reduced, and the accuracy of the test results is improved.

Description

technical field [0001] The invention relates to the technical field of coal quality analysis instruments, and more specifically relates to an online sample preparation and testing system. Background technique [0002] The total moisture in coal refers to the total free moisture in coal, that is, the sum of external moisture and internal moisture in coal. It is one of the important indicators to characterize the performance of coal, which is directly related to the transportation capacity, pricing and settlement, and affects the economic interests of both parties in the media transaction. [0003] The coal quality analysis industry often measures the total moisture of coal samples through the process of sampling, preparation and testing and analysis. The online sample preparation system commonly used in the prior art only performs preliminary crushing and shrinking of coal quality, and collects samples to prepare common coal samples. The full-moisture coal sample (referred ...
