Description
Technical Field
[0001] The utility model relates to the technical field of coal detection, in particular to a coal sample wrapping mechanism and a device for detecting carbon content in coal. Background Art
[0002] Carbon and hydrogen in coal are the main sources of heat. Their content determines the calorific value. The carbon content in coal is important for understanding the degree of coal metamorphism and coal properties; using carbon content to calculate the amount of oxygen (or air) consumed by coal combustion and combustion efficiency is also very important; carbon content is also the main indicator for calculating material balance in coal processing. Therefore, for combustion, the determination of carbon content is of great significance.
[0003] The workflow of the existing coal carbon content detection equipment first requires pretreatment of the coal sample. After combustion, carbon dioxide gas is generated and absorbed by an absorption device. Finally, the device that absorbs carbon dioxide is weighed. By comparing the mass difference before and after absorption, the carbon content in the coal can be calculated. However, when pretreating the coal sample, it is necessary to wrap the sample with tin foil. Since the tin foil cup that wraps the sample itself has small cracks, or the sample delivery mechanism has carbon powder, it may cause sample loss or mixing of foreign carbon-containing impurities, which will affect the carbon value determination. When weighing the absorption device, the workflow is cumbersome, time-consuming and labor-intensive, and it is difficult to display the results in real time. Utility Model Content

The baffle 302c blocks the opening 101c opened on the box body 101a, and the size of the baffle 302c is larger than the size of the opening 101c.
[0042] The rest of the structure is the same as that of Example 1.
[0043] Operation process: when the rotating plate 301a is turned to rotate, the fan 301b starts to blow away the coal powder that may remain on the first conveyor belt 102a and the second conveyor belt 102g, and the rotating plate 301a drives the connecting rod 302a to rotate. The telescopic rod 302b set on the connecting rod 302a turns the baffle 302c to make the baffle 302c rotate and connect to the box body 101a. When the rotating plate 301a rotates 90 degrees, the baffle 302c completely blocks the opening 101c opened on the box body 101a to prevent the mixing of foreign carbon-containing impurities due to the coal powder that may remain on the first conveyor belt 102a and the second conveyor belt 102g, thereby ensuring the accuracy of the test results.
[0044] Example 3

The scale plate 402c is fixedly connected to the lower layer of the placement rack 101e.
[0048] The rest of the structure is the same as that of Example 2.
[0049] Operation process: When the tin foil cup containing the coal sample is burned, the carbon dioxide generated by the combustion is discharged from the combustion furnace 101b together with other combustion gases and enters the collecting tube 401a. First, the gas passes through a collecting bottle 402b filled with a desiccant (such as anhydrous calcium chloride or quartz sand) to remove moisture therein, and then the gas enters the collecting bottle 402b filled with an alkaline solution (such as sodium hydroxide solution). The carbon dioxide reacts with the alkali to form carbonate, which is then absorbed. At this time, the two collecting bottles 402b have completed the collection, the two second springs 402a are tightened, the collecting bottle 402b is pressed down, and the weight change is read through the scale plate 402c to calculate the carbon content in the coal sample.
