Embodiment 1
[0027] like Figure 1-Figure 3 As shown, a coal ash sample preparation device includes a high-temperature furnace 1, a sample table 2, a thermocouple 3, a lifting device 4, a gas control system 5 and a control module 6, and is characterized in that it also includes a corundum tube 7 And the crucible 8, one end of the corundum tube 7 is closed, the other end is open, the closed end of the corundum tube 7 is embedded in the heating zone of the high temperature furnace 1, and the open end of the corundum tube 7 extends out of the heating zone of the high temperature furnace 1 , and cooperate with the upper surface of the lifting platform of the lifting device 4 through a flange to achieve a sealing effect. The crucible 8 includes a protective crucible 9 and a sample crucible 10, and the protective crucible 9 is set on the outside of the sample crucible 10 and higher than the sample crucible 10, so as to prevent the sample from polluting the sample table 2 under high temperature m...
Embodiment 2
[0029] like Figure 4 Shown, a kind of preparation method of coal ash sample, the steps are as follows:
[0030] Step 1, uniformly mixing coal ash and dextrin solution to obtain a coal ash mixture;
[0031] Step 2, put the sample crucible 10 made of alumina into the protective crucible 9 made of zirconia, and put the coal ash mixture directly into the sample crucible 10;
[0032] Step 3, place the crucible 8 at the center of the sample table 2, and use the lifting device 4 to adjust the height of the lifting table until the open end of the corundum tube 7 is flush with the lifting table of the lifting device 4, so that the sample table 2 is sealed on the corundum Inside the tube 7;
[0033] Step 4, adjust the gas control system 5 to feed gas into the corundum tube 7 according to the experimental requirements, and set the corundum tube 7 to a specific gas atmosphere;
[0034] Step five, according to the experimental requirements, the high-temperature furnace 1 is heated thro...
Embodiment 3
[0038] like Figure 5 Shown, a kind of preparation method of coal ash sample, the steps are as follows:
[0039] Step 1, uniformly mixing coal ash and dextrin solution to obtain a coal ash mixture;
[0040] Step 2, put the sample crucible 10 made of molybdenum into the protective crucible 9 made of graphite, press the coal ash mixture into a cylindrical sheet and put it into the sample crucible 10;
[0041] Step 3, place the crucible 8 at the center of the sample table 2, and use the lifting device 4 to adjust the height of the lifting table until the open end of the corundum tube 7 is flush with the lifting table of the lifting device 4, so that the sample table 2 is sealed on the corundum Inside the tube 7;
[0042] Step 4, adjust the gas control system 5 to feed gas into the corundum tube 7 according to the experimental requirements, and set the corundum tube 7 to a specific gas atmosphere;
[0043] Step five, according to the experimental requirements, the high temperat...
