Description
Technical Field
The utility model relates to coal sample system appearance equipment field, concretely relates to coal sample ventilation drying equipment.
Background
For coal quality analysis, it is actually a sampling analysis process. Coal is an uneven substance (granularity, mass characteristic distribution and the like), the sampled female parent is generally large (dozens of tons to tens of thousands of tons and the like), the process of extracting a representative sample capable of representing the mass and the characteristics of the whole female parent to the maximum extent is called 'sampling', and various methods such as mechanical sampling, manual sampling, semi-mechanical sampling and the like are provided at present. Each country has a mandatory standard and must comply with the standard for sampling.
After the sample is taken according to the standard, the next process is sample preparation, and the criterion of the sample preparation process is to gradually reduce the granularity and the mass of the sample on the premise of not damaging the representativeness of the sample until the granularity and the mass (weight) of the sample in laboratory tests are met. The sample preparation process generally comprises the processes of air drying, crushing, division, grinding and the like. The air drying (or heat drying, but the temperature should be less than 50 ℃) process is to reduce the moisture outside the sample, so as to facilitate the subsequent crushing and dividing process to be normally carried out. Crushing in the sample preparation process is a process for reducing the granularity of a sample. The reduction process is a process of performing representative quality reduction on a sample, the reduced sample must represent the coal quality characteristics of the sample before reduction, the reduction process is also a process of completing sample quantity reduction in the sample preparation process, and standard regulations in other processes should not allow coal sample loss. Because sample loss from non-fractionating processes (e.g., loss of coal fines, gangue being removed, etc.) can change the coal quality characteristics of the sample, selective (not necessarily artificial) sample loss is absolutely not allowed for the sample preparation process.
Currently, coal samples are mainly manufactured into three types according to national standards: the method comprises the steps of preparing a full water sample, a storage sample and an analysis sample, wherein the granularity, the water content and the like of the three samples are different, and the amount to be provided is different, for example, the full water sample with the granularity of 13mm needs to provide not less than 1.25 kg, the storage sample with the granularity of 3mm needs to provide not less than 0.7 kg, and the analysis sample with the granularity of 0.2mm needs to provide not less than 60 g. After different coal samples are made, in order to ensure the reliability of the samples, different coal samples need to be packaged by using a sample packaging device respectively for use in subsequent sample analysis. In the sample preparation operation, the coal sample needs to be dried by using drying equipment. The prior art mainly has the following problems:
firstly, the heating temperature of the existing drying equipment is uncontrollable and unadjustable, and the drying temperature can not be adjusted and controlled in real time according to the real-time conditions of each stage of coal sample drying. Because the temperature control of the drying temperature of the coal sample is very important, the drying temperature is not easy to be overhigh, and if the temperature is continuously overhigh, the characteristics of the coal sample are damaged; but the temperature is not too low either, which would affect the drying efficiency.
Secondly, the intelligent degree of the existing drying equipment is not enough, and the intelligent drying operation can not be carried out according to different environments and different coal samples. For example, in some special coal types (such as high-sodium coal), the total water content of the coal sample is high, the coal sample is pulverized, sticky, easy to form blocks and not easy to dry thoroughly, the existing equipment cannot distinguish, and if the drying is still performed according to the basic coal sample, the drying effect is obviously extremely poor. For example, in extreme high humidity and low temperature weather, if drying is performed for a fixed time according to basic environmental conditions, incomplete drying and poor drying effect are caused.
