Automatic dust removing method for sample preparation and dust removing system thereof

Abstract

The invention discloses an automatic dust removing method for the sample preparation and a dust removing system of the automatic dust removing method. The automatic dust removing method comprises the following steps: monitoring the working state of a sample preparing device in real time, judging the grade of the dust capacity according to the working state of the sample preparing device; and combining the working states of the dust capacity in different grades and the sample preparing device to control the power degree of the dust removing system. The dust removing system comprises a controller, a dust removing component, and a sample preparing device state detecting component used for detecting the working state of the sample preparing device in real time; the controller is connected with the dust removing component, and is provided with a stage grading judgment module in the working process of the sample preparing device and a dust capacity grading judgment module in the working process of the sample preparing device; and a sample preparing device state detecting component sends the collected sample preparing device working state signal to the controller, and the controller judges according to the collected sample preparing device working state and sends out a control order to the dust removing component. The automatic dust removing method and the dust removing system have the advantages of being high in degree of automation, controllable in dust removing process, capable of removing dust according to the actual working condition of the sample preparation and keeping the integrity of the material sample.

Description

technical field [0001] The invention mainly relates to the field of dust removal, in particular to a dust removal method and a dust removal system suitable for the field of sample preparation. 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 s...

Problems solved by technology

[0008] 3. The dust removal system cannot fully meet the actual needs of the sample preparation process. The sample preparation equipment starts immediately when it is turned on, and it is easy to take away part of the materials in the sample preparation process, which cannot guarantee the integrity of the material samples, and ultimately affects the accuracy of sample preparation and measurement. precision
