Description

Distributed multi-point sampling and sample preparation system from scattered to centralized

Technical Field

The utility model relates to sampling and sample preparation equipment, in particular to a distributed multipoint sampling and sample preparation system, which belongs to the field of sampling and sample preparation in the coal or ore industry.

Background

In the field of sampling and sample preparation of coal and ore, a common sample preparation method generally comprises the steps of sampling a coal sample or an original ore sample at a sampling end, carrying out primary crushing and division at the sampling end, and then barreling (about 15-30 kg/barrel) or bottling (less than or equal to 3 kg/bottle) the raw coal/ore sample obtained by division by using a sample collection device. According to the related requirements of GB/T19494.1-2004 part 1 sampling method for mechanized sampling of coal, in order to prevent the excessive loss of water in the coal sample during the sampling and preparation process, the primary crushing particle size of the raw coal sample is not smaller than 13mm in the sampling stage, therefore, the sample collection and retention amount is more than 15 kg. With specific reference to the following table:

GB/T 19494.1-2004

TABLE 3 minimum mass of general analytical test Total sample, Total moisture Total sample/reduced Total sample

Therefore, if the raw coal/ore sample is subjected to barreling, the raw coal/ore sample needs to be transferred to a sample preparation end for sample preparation in a manual or special track transfer trolley mode, the former has high labor intensity and cannot ensure the safety of the raw coal/ore sample, and the latter generally needs to span an outdoor special track, so that the cost is high, the investment is large, and the influence of weather is large; if the raw coal/ore sample is transported in a bottling mode by utilizing gas conveying, the number of sample bottles is large, the gas conveying task is heavy, and matched automatic facilities such as bottling at a sampling end, uncapping at a sample preparation end and the like are complex and have high failure rate.

Therefore, a distributed-to-centralized multipoint sampling and sample preparation system with more reasonable layout, which can ensure the transportation safety of raw coal/ore samples and greatly reduce the transportation quantity becomes the goal pursued by the technical personnel in the field.
