Description

technical field [0001] The invention relates to the field of coal sample preparation equipment, in particular to an intelligent sampling and preparation system. Background technique [0002] For coal quality analysis, 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. Each country has mandatory standards, and sampling work must be carried out in accordance with the standards. [0003] After the sample is collected according to the standard, the next process is sam...

AI Technical Summary

Problems solved by technology

[0006] (1) The degree of automation of transshipment is not high

The coal material transfer of the sample (sample barrel) from the sampling end to the sample preparation end usually requires manual handling (manually transported to the sample preparation end, or manually transporting the sample to the conveying equipment and then transported to the sample preparation end, or manually transporting the sample from the sample preparation end) Unloading on equipment), which leads to high labor intensity and low work efficiency

Especially when the transfer distance is very long, and traditional conveying equipment such as conveyor belts cannot be used for transmission, it cannot meet the needs of rapid and large-scale centralized transportation

It makes it impossible to meet the operation requirements of unattended and automatic docking in the sample collection system

[0007] (2) Poor transshipment safety

Due to the need for manual handling, there is a risk of artificial sample change during the transfer process, and the sample bucket will drop and the sample will be spilled

[0008] (3) The degree of automation of sample preparation is not high and the efficiency of sample preparation is low

The manual method is used to prepare samples step by step, and the materials are manually transferred from the upper-level sample preparation module (equipment) to the next-level sample preparation unit (equipment), which cannot reflect automation at all, is labor-intensive, low-efficiency, and manual intervention in each link prone to falsification

[0009] (4) The traditional belt conveying is used for step-by-step sample preparation. In this way, the material is transferred from the lower output port of the upper-level sample preparation module (equipment) to the upper input port of the next-level sample preparation unit (equipment). Extend the length of the conveyor belt to reduce the lifting slope, and this will inevitably make the entire sample preparation system occupy a large area and the space utilization rate is not high

[0010] (5) The multi-bucket conveying method is used to prepare samples step by step. First, when conveying in this way, the coal samples are distributed in many small buckets, so that the coal samples are scattered and transported flat, and the surface area of ​​the coal samples exposed to the air is relatively large. , the loss of water is more, which affects the accuracy of subsequent analysis and testing; second, the contact area between the coal sample and the hopper wall in this transportation method is also large, so that there are many residues of the coal sample in the hopper, which will pollute the next sample preparation. It affects the accuracy of subsequent analysis and testing; the third is that when multi-bucket transportation is actually used, only a small part of the buckets are filled with coal samples each time, and the actual use efficiency of all equipment is low

Fourth, regardless of belt conveying or multi-bucket conveying, there is a problem of large floor space for the installation of conveying equipment between multiple sample preparation modules (equipment)

This kind of device is complex, occupies a large area, and has high production and maintenance costs; second, it takes a certain amount of time to combine samples into batches, resulting in low work efficiency, and cannot well meet the needs of automatic sample collection.

[0012] (7) The safety is poor. Since the material needs to be manually transferred from the sampling end to the sample preparation end, it cannot reflect automation at all, so there is a phenomenon of manual sample replacement and fraud during the handling process of the sampling end.
