Dispersion-to-concentration multipoint distributed sampling and sample preparation system

Abstract

The invention discloses a multi-point distributed sampling and sample preparation system from dispersion to concentration. The system is characterized by comprising a remote distributed sampling and sample preparation system for sampling, primary crushing, division, preparation and collection of a primary sample and / or a secondary sample of solid mineral aggregate at each distribution point; the pneumatic conveying system or the track conveying system is used for intelligently transferring samples; the centralized sample preparation system is used for preparing a third-stage sample by utilizing the first-stage sample and / or the second-stage sample; the cleaning system is used for cleaning containers such as sample bottles, and the sample storing and checking management system is used for storing and checking the samples; the remote distributed sample collecting and preparing system, the centralized sample preparing system, the cleaning system and the sample storing and checking management system are communicated through a pneumatic conveying system or a track conveying system and convey empty bottles or sample bottles mutually. According to the invention, low total moisture loss of the prepared sample can be ensured, and the conveying quantity of the original sample can be greatly reduced; and the safety of the original sample transfer link is ensured, and meanwhile, the overall sampling and sample preparation efficiency is improved.

Description

technical field [0001] The invention relates to sampling and sample preparation equipment, in particular to a multi-point distributed sampling and preparation system from dispersal to concentration, which belongs to the field of sampling and sample preparation in the coal or ore industry. Background technique [0002] In the field of coal and ore sampling and sample preparation, the more common sampling and preparation methods are generally to take coal samples or raw ore samples at the sampling end, and perform primary crushing and reduction at the sampling end, and then use the sample collection device to reduce the obtained samples. Raw coal / mine samples are packed into barrels (about 15-30kg / barrel) or bottled (≤3kg / bottle). According to the relevant requirements of GB / T19494.1-2004 "Coal Mechanized Sampling Part 1 Sampling Method", in order to prevent excessive loss of coal sample moisture during the mining and processing process, the primary crushed particle size of th...
