Description

An automatic feeding device for samples

technical field

The invention mainly relates to the field of material sample collection and analysis equipment, in particular to an automatic feeding equipment for samples.

Background technique

For the sampling and analysis of materials (such as ore and coal), each country has mandatory standards, and sampling and analysis must be carried out in accordance with the standards. The principle of the sample collection and analysis process is to gradually reduce the particle size and quality of the collected samples on the premise of not destroying the representativeness of the samples, until the particle size and mass (weight) accuracy requirements of the laboratory test are met. , and then carry out relevant test analysis on samples that meet the requirements. During this process, there can be no loss of samples, and no physical or chemical changes can occur in the samples, otherwise the final test results will be affected.

Take coal material analysis as an example, 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. After the sample is collected according to the standard, the next process is sample preparation. The sample preparation process generally includes air drying, crushing, shrinking, grinding and other processes. After the sample is prepared, proceed to the next step of sample test analysis. In the process of coal sampling and analysis, moisture testing instruments are used to test and analyze the moisture content of coal samples. Coal moisture is the most basic index to evaluate the economic value of coal. Because changes in moisture in coal will cause changes in the content of other components and calorific value, which will have a certain impact on the quality inspection, measurement, acceptance, and management of coal. Therefore, accurate determination of moisture in coal is of great significance to the production management and operation of coal. Of course, for other material samples, it is also necessary to test and analyze the moisture content if necessary.

In the existing coal quality sampling and preparation system, there are the following technical problems regarding the feeding operation:

(1) The degree of automation is not high, and it cannot meet the unattended operation requirements in the sample collection and preparation system. Coal samples are usually loaded and transferred manually, which is labor-intensive and low-efficiency, and the operation of the equipment is unstable due to irregular operations, which affects the overall operation of the system.

(2) Poor security. Due to the need to manually unlock and pour the material, there is a risk of artificial sample change, sample bucket falling and sample spilling.

(3) The degree of intelligence is low. When the sample barrel is finished emptying, it cannot be immediately transferred to the working station for the next batch of reloading, making it necessary to prepare a lot of sample barrels to meet the development of the system. Not only is the cost high, the work efficiency is low, and it cannot be quickly It can better meet the requirements of continuous operation and efficient operation of the sample collection and preparation automation system.

(4) Environmental pollution is serious. The existing material is easy to cause dust when unloading, which not only endangers the health of operators, but also is not conducive to environmental protection.

(5) It is easy to cause sample contamination. The existing sample barrels cannot be cleaned automatically after loading. Manual cleaning is not only labor-intensive and low in work efficiency; but also manual cleaning is likely to cause mistakes and omissions, resulting in the residue of the current batch in the sample barrels and affecting the next batch of loaded samples. accuracy and representativeness.
