Coal coking automatic sample preparation system

Abstract

The invention relates to a coal coking automatic sample preparation system which comprises a sample-preparation working station, an automatic delivery unit, a discharging unit and a controlling unit, wherein the sample-preparation working station, the automatic delivery unit and the discharging unit are interlocked in sequence under the controlling action of the controlling unit, automatic feeding, crushing, shrinkage, canning, automatic delivery, sample sealing, information identification code spraying and rejected sample collection are performed to the raw material ore; and the controlling unit takes a PLC control system as a core part and comprises a data acquisition device, a system controller, an operating panel, a labelling machine controller, a jet printer controller, a packaging machine controller and a computer monitoring system, and the PLC control system is communicated with the seven parts through a filed bus. The invention has the advantages that the automatic feeding, the crushing, the shrinkage, the canning, the sample sealing, the information identification code spraying and the rejected sample collection automatization are finished for the raw material ore.

Description

technical field [0001] The present invention relates to a coal coking sample preparation system in the iron and steel, coking, coal and other industries, in particular to an automatic system for automatic feeding, crushing, shrinking, canning, sample sealing, information identification and code spraying, and discarded sample collection for raw material ores. Sample preparation system. Background technique [0002] In the prior art, the preparation of material samples such as coal or ore in conventional laboratories is mainly based on the operation of single equipment, such as large jaw crushers, small jaw crushers, and double stick crushers, each of which is independent The operation requires the experimenters to complete the operation of a predetermined process of the corresponding equipment according to the requirements for sample preparation. When many types of samples need to be prepared, this operation process is often very cumbersome, and the working environment is ver...

[0002] In the prior art, the preparation of material samples such as coal or ore in conventional laboratories is mainly based on the operation of single equipment, such as large jaw crushers, small jaw crushers, and double stick crushers, each of which is independent For the operation, the experimenter must complete the operation of a predetermined process of the corresponding equipment according to the requirements for sample preparation. When there are many types of samples that need to be prepared, this operation process is often very cumbersome, and the working environment is very poor, indoor crushing, etc. It will cause great personal injury, many operating links, high probability of manual error and misoperation, cannot guarantee the accuracy of the sample preparation process, and reduces the reliability of the experimental results
