Description

Technical Field

[0001] The invention relates to a module splicing joint sample preparation system for automatically preparing total moisture samples, reference samples and analysis samples of coal of various particle sizes, and belongs to the field of coal sampling and sample preparation. Background Art

[0002] In the field of coal sampling and sample preparation, sample preparation generally involves preparing the incoming material into 6mm or 13mm primary samples, then using the primary samples to prepare the required full moisture samples through reduction, using the full moisture samples to prepare 3mm reference samples through crushing and reduction, and using the reference samples to prepare 0.2mm analytical samples through grinding, reduction, and drying. The more common sample preparation equipment usually includes the following four types: (1) unmanned coal automated sample preparation system; (2) environmentally friendly combined sample preparation unit; (3) manual sample preparation with a single unit; (4) pure manual sample preparation. The second two sample preparation methods (3) and (4) are gradually being eliminated due to the high labor intensity and the fact that the prepared samples are often affected by human subjective factors. Therefore, the commonly used methods at present are only unmanned coal automated sample preparation system and environmentally friendly combined sample preparation unit, but from the actual use, both methods also have their own shortcomings. The unattended coal automatic preparation system adopts a planar layout method, which occupies a large area, has many intermediate transfer links in the coal flow, and has low efficiency. In addition, the transfer process inevitably has coal spillage, coal leakage, dust and other phenomena, which are not conducive to the working environment. In addition, the entire system is huge, and the one-time investment and maintenance costs are high. Although the environmentally friendly joint sample preparation unit adopts a vertical layout structure, the overall volume has also been greatly improved, but the functionality is often reduced. For example, it cannot prepare 0.2mm analytical samples, has no automatic packaging function, and cannot be connected online with other automated equipment (such as powder conveying, pneumatic conveying, storage and inspection sample management system, etc.); at the same time, the unattended coal automatic sample preparation system and the environmentally friendly joint sample preparation unit adopt an integral design, and there are many horizontal conveying belt devices, and the components are intertwined. During installation and debugging, not only the workload is large, but also the efficiency is extremely low, which often makes the project progress difficult to meet expectations; in addition, both units cannot realize the independent preparation or combined preparation function of a single sample (moisture sample, reference sample, analytical sample), so they cannot meet customers' increasingly diverse needs for sample preparation. Meanwhile, the unattended coal automatic sample preparation system and the environmentally friendly combined sample preparation unit in the prior art generally only have the sample preparation function, and after the sample preparation is completed, it needs to be transported to the packaging unit for packaging.

[0003] Therefore, a modular joint sample preparation system with a more complete and reasonable structure, small footprint, modular design, and can be used after on-site splicing, and which can be used both individually and in combination, has become the goal pursued by technical personnel in this field. Summary of the invention
