Automatic sample preparation system with weighing and data analysis functions

Abstract

The invention discloses an automatic sample preparation system with weighing and data analysis functions, comprising a control system, a mechanical arm module and a weighing module, wherein the mechanical arm module is connected with the control system and is used for receiving an instruction issued by the control system and performing pick-and-place and transfer operations on a sample loading container; the weighing module is connected with the control system and is used for weighing the sample weight and storing weight data to the control system; and the control system is used for storing the weight data of each sample in a sample preparation process, and calculating one or more results of a loss amount, a loss rate, a residual amount, a collection rate, a water removal amount and a water removal rate of the sample in the sample preparation process. The automatic sample preparation system disclosed by the invention has the advantages of centralized weighing, accurate and reliable weighing, simple structure, lower system cost and capability of realizing data analysis.

Description

technical field [0001] The invention mainly relates to the technical field of sample preparation, in particular to an automatic sample preparation system with weighing and data analysis functions. Background technique [0002] The automatic sample preparation system automatically prepares samples such as full water samples, storage and inspection samples, and analysis samples according to the steps of crushing, shrinking, and drying of the original coal sample. The system generally includes primary crushing, primary shrinking, and Secondary crushing and shrinking, drying and powdering shrinkage, etc. The first-level reduction will produce a full water sample, the second-level crushing will produce an inspection sample, and the drying and pulverization will produce an analysis sample. At present, users who use the automatic sample preparation system for sample preparation are paying more and more attention to the weight of each sample preparation during the sample preparatio...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the installation of multiple weighing devices, the cost of the entire system is too high, the system has problems such as complex structure and prone to failure, and once a problem occurs in a certain sample preparation process, the prepared sample does not meet the requirements. Whether the weight is qualified or not is judged, and the problems that occur in the system cannot be checked and remedied through the weighing results

[0004] 2. The sample preparation process of the automatic sample preparation system includes more than a dozen units, and there will be loss and residue of sample volume in each link. The loss and loss rate of each link will affect the experimental results of sample preparation. The amount / residual amount / collection rate / water removal rate is calculated and judged. The existing sample preparation system cannot monitor the sample changes and results in the whole process of sample preparation in real time.

[0005] 3. The weighing device in each link of the automatic sample preparation system in the prior art only realizes the weighing of the sample weight result of a single sample, and lacks statistical analysis of historical data. After the system has been running for a long time, there are abnormal trends and cannot be timely Find
