Description

technical field [0001] The invention relates to the field of coal sample preparation equipment, in particular to an intelligent coal sample 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 samp...

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) The degree of intelligence in sample preparation is not high, the efficiency of sample preparation is low, and the safety is poor

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

[0008] (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

The multi-bucket transportation method is used to prepare samples step by step. First, the coal samples are spread out and transported flat. The surface area of ​​the coal samples exposed to the air is large, and the water loss is large, which affects the subsequent analysis and test accuracy. Second, this transportation method The contact area between the coal sample and the hopper wall is also large, so that there are many coal samples remaining in the hopper, which will cause pollution to the next sample preparation and affect the accuracy of subsequent analysis and testing; Conveying only a fraction of the hoppers with coal samples, all equipment is actually used less efficiently

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)

[0009] (5) Part of the existing sample collection and processing system has a low degree of automation. Most of the sampled coal samples are transported through manual sample collection and manual batching. The labor intensity is high, the work efficiency is low, and the degree of automation is not high. Autorun Job Requirements

At the same time, due to the need to artificially combine samples into batches

There is a risk of artificial sample change, the sample bucket falls and the sample spills, and the safety is poor

[0010] (6) Part of the existing sample collection and processing system is low in intelligence and does not have a cache function. It can only handle some batches of samples with a small number of samples and a small amount of samples in each batch. Once the batch of samples When the amount of samples in each batch is large, the existing sample collection and processing system cannot meet the requirements, and cannot handle multiple batches and a large number of combined samples into batches

For example, it is not possible to complete the unified automation operations of multiple batches of sample preparation and batching, multiple batches of empty barrels, and multiple batches of post-batch sample preparation and batching at the same time.

[0011] (7) Part of the existing sample collection and processing system is bulky and occupies a large area, which is not suitable for flexible placement and use in industrialization. make the system bulkier and more complex
