Description

Sample cup manufacturing device, sample wrapping machine and coal sample detection system

Technical Field

The utility model relates to the technical field of coal sample element detection, in particular to a sample cup manufacturing device. In addition, the utility model also relates to a sample wrapping machine comprising the sample cup manufacturing device. In addition, the utility model also relates to a coal sample detection system comprising the sample wrapping machine.

Background

Carbon and hydrogen are main constituent elements of organic matters of coal, and the sum of the carbon and the hydrogen and oxygen accounts for more than 95% of the organic matters of the coal; while nitrogen is the only element in the coal that exists entirely in an organic form. Therefore, knowing the hydrocarbon nitrogen content in the coal has important significance for knowing the property of the coal, checking other index detection results and calculating indexes such as heat, materials, pollutant emission and the like in the coal application process.

The method for detecting hydrocarbon nitrogen elements in coal in the prior art is based on various detection instruments, and the detection instruments can only automatically complete the detection process after a sample to be detected enters the detection instruments, and still need manual operation for procedures such as weighing the sample to be detected, preparing a sample to be detected for tinfoil, placing the sample to be detected into a specified position of the detection instruments and the like.

The detection of hydrocarbon nitrogen in coal requires compacting and exhausting the coal sample carrier of the hydrocarbon nitrogen analyzer, namely tin foil. In the process of packaging coal samples, the operation is mostly performed manually, and in order not to influence the detection result, the operation cannot be performed by direct hand contact, so that the packaging cannot be performed directly by using tinfoil paper, and the packaging tinfoil paper is generally folded by a professional company to manufacture a ship-shaped sample cup, and then stacked in a sealed plastic bottle for packaging and sale; when the coal sample is required to be packaged, a ship-shaped sample cup is taken out of the sealed plastic bottle by using tools such as tweezers, and the like, the coal sample is quantitatively (generally 60 mg+/-0.03 mg or 80 mg+/-0.03 mg) added, and then the tools are manually used for non-contact packaging to compress and discharge gas. The manufacturing difficulty of the ship-shaped sample cup is high, and the selling price is high, so that the detection of hydrocarbon nitrogen in the coal is easily limited by external conditions, and the cost is increased; the ship-shaped sample cup has an irregular shape with a fixed structural style, is inconvenient to manually carry out non-contact packaging operation by using a tool, and is easy to cause the problems of sample leakage, breakage, unsealing, incomplete gas discharge and the like.
