Description
Technical Field
The invention mainly relates to the field of material sample collecting and analyzing equipment, in particular to automatic feeding equipment for samples.
Background
For sample collection and analysis of materials (such as ores and coals), the standards are mandatory in all countries, and the sample collection and analysis must be carried out according to the standards. The criterion of the working process of sample collection and analysis is that the granularity and the quality of the collected sample are gradually reduced on the premise of not damaging the representativeness of the sample, the quality of the collected sample is gradually reduced until the precision requirements of laboratory tests on the granularity and the quality (weight) of the sample are met, and then the related test analysis is carried out on the sample meeting the requirements. There can be no loss of sample in this process, and some physical or chemical changes in the sample can not occur, which would otherwise have an impact on the final test results.
As exemplified by coal analysis, is in fact a process of sampling analysis. Coal is a non-uniform substance (particle size, mass characteristic distribution, etc.), the sampled female parent is generally larger (tens to tens of thousands of tons are different), the process of pumping a representative sample representing the mass and characteristic of the whole female parent to the maximum extent is called sampling, and at present, various methods such as mechanical sampling, manual sampling, semi-mechanical sampling, etc. are available. After the sample is collected according to the standard, the next process is sample preparation, and the sample preparation process generally comprises the processes of air drying, crushing, dividing, grinding and the like. After the sample is prepared, the next sample test analysis is carried out. In the sampling and analysis process of coal, a moisture testing instrument is used for testing and analyzing the moisture content of the coal sample. The moisture of coal is the most basic index for evaluating the economic value of coal. Because the change of moisture in the coal can cause the content change and the heating value change of other components, the quality detection, the measurement, the acceptance and the management of the coal are affected to a certain extent. Therefore, accurately measuring the moisture in the coal has great significance for the production management and management of the coal. Of course, for other material samples, a test analysis of the moisture content is likewise required if necessary.
In the existing coal sampling and sample preparing system, the following technical problems exist with respect to feeding operation:
(1) The automation degree is not high, and the unattended operation requirement in a sampling and sample preparing system can not be met. The loading and transferring of coal samples are usually manual carrying and manual loading, so that the labor intensity is high, the working efficiency is low, and the whole operation of the system is influenced due to unstable equipment operation caused by nonstandard operation.
(2) The safety is poor. Because of the need of unlocking and pouring by people, the risk of sample falling caused by artificial sample changing and sample barrel falling exists.
(3) The intelligent degree is low. After the sample barrels are poured, the sample barrels cannot be immediately transferred to a use station for recharging of the next batch, so that a plurality of sample barrels are required to be prepared to meet the development of a system, the cost is high, the working efficiency is low, and the requirements of continuous operation and efficient operation of a sampling and sample automation system cannot be well met.
(4) The environmental pollution is serious. The existing material pouring is easy to cause dust emission, which not only endangers the health of operators, but also is unfavorable for environmental protection.
(5) Sample contamination is easily caused. The existing sample barrel cannot finish automatic cleaning after feeding, and manual cleaning is high in labor intensity and low in working efficiency; moreover, the manual cleaning is easy to cause error missing cleaning, so that the batch of samples remains in the sample barrel to influence the precision and representativeness of the samples loaded in the next batch.
