Description

Technical Field

[0001] The utility model relates to the technical field of chemical inspection clamping and transporting equipment, in particular to an automatic clamping tool for an infrared carbon-sulfur analyzer. Background Art

[0002] The infrared carbon and sulfur analyzer uses a high-frequency induction heating furnace to burn the sample, and the infrared absorption method is used to test the mass fraction of carbon and sulfur in the sample. The carbon and sulfur in the sample of the infrared carbon and sulfur analyzer are heated at high temperature in the crucible under oxygen-rich conditions and oxidized into carbon dioxide and sulfur dioxide gas. After treatment, the gas enters the corresponding absorption cell, absorbs the corresponding infrared radiation, and is forwarded by the detector as a signal, and the result is output by computer processing. This method is accurate, fast, and highly sensitive. It is used for both high and low carbon and sulfur contents. The infrared carbon and sulfur analyzer using this method has a high degree of automation and is suitable for occasions with high analytical accuracy requirements.

[0003] Carbon and sulfur analysis is an important step in the inspection process of the furnace laboratory. In the process of carbon and sulfur analysis in the furnace laboratory, after the analysis of the sample is completed, it is necessary to manually remove the used crucible with tweezers, discard it in the waste crucible box, and then place the next sample crucible. After the carbon and sulfur analysis sample is completed, it is necessary to manually remove the used crucible with tweezers, discard it in the waste crucible box, and then place the next sample crucible. After the analysis is completed, the high-temperature crucible is easy to burn, and if there are flammable materials in the waste sample tray, it will cause fire.

[0004] Therefore, it is urgent to design an automatic clamping tool for an infrared carbon-sulfur analyzer to solve the problem of burns and flammability when the crucible of the existing infrared carbon-sulfur analyzer is manually taken out with tweezers after the crucible is heated.
