Automated Sample Preparation System with Parallel Processing

Abstract

An automatic sample preparation system having a parallel processing function comprises a primary treatment unit (1), a secondary treatment unit (2) and a tertiary treatment unit (3) for preparing samples. The primary treatment unit (1) performs a sample treatment on a material and respectively obtains total-moisture sub-samples and a first material to be sample-prepared that is used to be processed by the secondary treatment unit (2). The secondary treatment unit (2) performs the sample preparation treatment on the first material to be sample-prepared and respectively obtains a sample for back-checks and a second material to be sample-prepared that is used to be processed by the tertiary treatment unit (3). The tertiary treatment unit (3) performs the sample preparation treatment on the second material to be sample-prepared and obtains an analysis sample. The system is simple and compact, is easy and flexible to operate, allows sample preparation units to perform treatment in parallel, can prepare three types of samples having different specifications at the same time; and accordingly the system has a high automatic degree of sample preparation, lowers labor intensity and improves sample preparation efficiency.

Description

technical field [0001] The invention mainly relates to the field of coal sample preparation equipment, in particular to an automatic sample preparation system with parallel processing function. Background technique [0002] For coal quality analysis, it is actually a process of sampling analysis. Coal is an inhomogeneous substance (particle 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), and the samples that can represent the quality and characteristics of the entire stock sample are drawn to the maximum extent. The process of sampling representative samples is called "sampling". At present, there are many 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. [0003] After the sample is collected according to the ...

Problems solved by technology

[0006] (1) Manual step-by-step sample preparation is labor-intensive and inefficient, and manual intervention in each link is prone to fraud

Dust pollution is likely to occur during the sample preparation process, which affects the service life of the equipment and the health of the operator;

[0007] (2) The method of simple combination of artificial step-by-step sample preparation equipment, the combination of processing equipment at all levels is relatively random and not scientific enough, and requires manual participation, and does not realize the whole process of automation; and after the sample is sent to the front end, it needs to wait until the sample has passed through the entire sample preparation process. The next sample can only be sent after the transfer is completed, and it cannot be processed in parallel at the same time, resulting in low system operation efficiency and greatly affecting the timeliness of sample preparation.
