[0020] Working Principle: After the graphite ore is crushed, it is accurately weighed using an analytical balance and placed in a special ceramic crucible. The crucible is then placed in a high-frequency induction combustion chamber 1, the furnace door is closed, and the instrument automatically introduces oxygen and starts high-frequency heating. The sample burns at high temperature, and the gas produced carries dust into the gas path. The dust is first filtered by a dust removal device, and then moisture is removed through a drying tube to obtain a clean mixed gas. The purified gas enters the infrared detection cell of the infrared carbon-sulfur detection chamber 2, which is used to detect the fixed carbon content in the graphite ore. When infrared light of a specific wavelength passes through the gas, it is absorbed by carbon dioxide and sulfur dioxide. The detector records the absorption intensity and converts it into the concentration signal of the corresponding element. The software of the data processing computer 3 calculates the mass fraction of carbon and sulfur based on the signal intensity. The system displays the results, allows for direct printing or data storage. The base 4 supports the high-frequency induction combustion cabinet 1, the infrared carbon-sulfur detection cabinet 2 for fixed carbon content in graphite ore, and the data processing computer 3. The support frame 5 supports the data processing computer 3 via a lifting rack 6, transmission box 7, slide block 8, and frame 9. The lifting motor 10 is powered by an external or standby power supply. The lifting motor 10 is controlled by a controller. The lifting motor 10 drives the main bevel gear 11 to rotate, which in turn drives the secondary bevel gear 12. The secondary bevel gear 12 drives the double-threaded screw 13 to rotate. The threads on both sides of the double-threaded screw 13 run in opposite directions. The double-threaded screw 13 drives two slide bars 14 to move closer together, and the slide bars 14 drive the hinge rod 1... 5. Movement: The hinge rod 15 and the main sprocket 16 have an eccentric structure. When the hinge rod 15 moves, it can drive the main sprocket 16 to rotate. The two main sprockets 16 rotate in opposite directions. The main sprocket 16 can drive the chain 17 to rotate, and the chain 17 can drive the auxiliary sprocket 19 to rotate. The radius of the main sprocket 16 is more than three times the radius of the auxiliary sprocket 19, which can produce an acceleration effect on the auxiliary sprocket 19. The auxiliary sprocket 19 can drive the transmission gear 20 to rotate, and the transmission gear 20 can drive the lifting rack 6 to move upward. The lifting rack 6 can drive the transmission box 7 to move upward. The transmission box 7 drives the data processing computer 3 to move upward through the slide 8 and the frame 9. When the position needs to be adjusted, the power supply of the power motor 21 is turned on. The power supply is an external power supply or... The self-contained power supply and the drive motor 21 are controlled by a controller. The drive motor 21 can drive the drive wheel 22 to rotate, which in turn drives the transmission belt 23 to rotate.
