Intelligent and full-automated sampling, sample preparation and testing system for raw material

Abstract

The invention relates to an intelligent and full-automated sampling, sample preparation and testing system for a raw material, which comprises a sampling and sample preparation integrated unit, a pneumatic sample delivering unit, an analysis and test unit, a storage unit and a system control unit, wherein the sampling and sample preparation unit is used for collecting samples, preparing analysis samples and samples for back-check, detecting the moisture content of the samples and uploading the detected sample moisture content data to the system control unit; the analysis and test unit is usedfor testing various performance indexes of the samples; the storage unit is used for storing the samples for back-check for re-check and verification in case of quality objection; and the pneumatic sample delivering unit is between the sampling and sample preparation integrated unit and the analysis and test unit and respectively conveys the analysis samples, the samples for back-check prepared bythe sampling and sample preparation integrated unit to the analysis and test unit and the storage unit. The system of the invention can realize unattended full-automated sampling, sample preparation,testing and storage and the automatic transmission of the samples, and ensures that various quality data of the samples to be authentic and accurate and the system error is within the standard permissible range at the same time.

Description

technical field [0001] The invention belongs to the field of quality inspection of raw materials and fuels, and in particular relates to an intelligent and fully automatic collection and production system for raw materials. Background technique [0002] At present, the quality management of bulk raw materials and fuels in steel, coal, electric power, petroleum, chemical and other industries is complex and cumbersome. Raw materials and fuel resources are increasingly scarce, prices fluctuate greatly, and adulteration and fraud are frequent. Suppliers raise various quality objections and re-inspections Requirements, new challenges and refined requirements are put forward for the quality management of raw materials and fuels. For a long time, the operating environment of raw materials and fuels has been harsh, dust, noise, mechanical damage, etc. have seriously endangered the health of workers, and there are many materials, large batches, high labor intensity for workers, and c...

AI Technical Summary

Problems solved by technology

[0008] 2) Assay link: Assay results are highly dependent on assayers, equipment, and instruments, and there are many interference factors, which can easily produce assay errors and affect the authenticity of data

The large sample obtained from sampling is transported to the sample preparation, the small sample obtained from the sample preparation is transported to the laboratory, and the storage and inspection sample obtained from the sample preparation is transported to the storage and inspection cabinet, etc. The material transfer method has not been fully automated

[0010] 4) Adaptability to complex working conditions: materials in special states such as high-moisture powder, high-viscosity materials, super-large-grained materials, and ultra-high-hardness materials rely on manual intervention, and the system adaptability of each link is poor
