Automatic sample preparation system with parallel processing function

Abstract

The invention discloses an automatic sample preparation system with a parallel processing function. The automatic sample preparation system comprises a first-stage processing unit, a second-stage processing unit and a third-stage processing unit which are used for preparing samples, wherein the first-stage processing unit is used for carrying out sample preparation to respectively obtain a total moisture sample and a first to-be-sample-prepared material which is to be processed by the second-stage processing unit; the second-stage processing unit is used for carrying out the sample preparation on the first to-be-sample-prepared material to respectively obtain a finding-storing sample and a second to-be-sample-prepared material which is to be processed by the third-stage processing unit; the third-stage processing unit is used for carrying out the sample preparation on the second to-be-sample-prepared material to obtain an analyzing sample. The automatic sample preparation system has the beneficial effects that the operation is convenient and flexible, each sample preparation unit is processed in parallel, three types of samples of different specifications can be simultaneously prepared, the automation degree of the sample preparation is extremely high, the labor intensity is greatly reduced, and the sample preparation efficiency is greatly improved.

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 ...

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.
