Description

Technical Field

[0001] The present invention relates to a drop-type high-temperature calorimeter device in calorimetry, and more specifically to a dual-calorimeter rotating tray bracket for a drop-type high-temperature calorimeter. Background Art

[0002] Heat capacity is the sum of the energy contributions of internal lattice, electrons and other forms of motion in a material system, and is a basic thermal property parameter of a material. Through the accurate measurement of heat capacity, basic thermodynamic data such as the enthalpy, entropy, and Gibbs free energy of a material can be obtained, the structure and phase change of the material can be understood, and it is also a method to obtain the lattice vibration and electron energy level transition of the microscopic structure of the material and to understand the superconducting phenomenon, magnetic action mechanism, and structural distortion. Therefore, obtaining accurate data of the heat capacity of a material is of great significance for exploring and designing new materials, optimizing the preparation process of materials, and promoting the understanding and development of material science.

[0003] The drop-type high-temperature calorimeter is one of the most accurate and reliable methods for measuring the enthalpy value and heat capacity of a material in the high-temperature region. However, during high-temperature tests, the copper calorimeter often has a long heating and cooling time, resulting in a long overall test time and low test efficiency, and most of the time is used to cool down to a constant room temperature. Using two calorimeters will cause the test to be alternately switched, so that the two calorimeters work alternately; when one calorimeter is heating up, the other calorimeter is cooling down and waiting at a constant temperature. However, this operation requires a relatively stable and precise docking method. Therefore, there is an urgent need to develop a dual-calorimeter rotating tray bracket with high stability, tightness, adjustability, and repeatability to meet the urgent need for accurate and efficient calorimeter tests.

[0047] The usage method of the present invention is as follows:

[0048] (1) Assemble the two calorimeters in the two calorimeter grooves 101 on the calorimeter rotating tray 1 respectively and fix them well;

[0049] (2) Rotate the rotating handle 102 to make one of the calorimeters reach the designated position. After rotating the calorimeter rotating tray 1, adjust the adjusting screw B20302 on the positioning buckle support column 203 to make the positioning buckle 103 fit tightly with the positioning buckle support column 203, and adjust the horizontal distance of the support tray 204 through the adjusting screw A20201. Finally, align the sample inlet of the calorimeter with the sample outlet of the high-temperature furnace and be on the same vertical line longitudinally;

[0050] (3) When the experiment starts, conduct a sample dropping experiment on one of the aligned calorimeters. After the sample is dropped, the calorimeter conducts a temperature rise test. At this time, the other calorimeter is in a constant temperature waiting for testing state;

[0051] (4) When the first group of experiments is over, rotate the calorimeter rotating tray 1 through the rotating handle 102 to swap the positions of the calorimeter in the waiting for testing state and the calorimeter after the test is over. Repeat the experimental step (2) to adjust the distance of the calorimeter, and then conduct the second group of experiments;

[0052] (5) While the second group of experiments is being conducted, operations such as cooling and constant temperature wiping can be carried out on the first group of calorimeters. Then, the cleaned calorimeters are in a state waiting for experiments;

[0053] (6) Conduct cyclic experiments such as experiments, rotating and swapping positions, precisely adjusting positions, cooling and maintaining a constant temperature, and cleaning in sequence, which can save a lot of time and achieve the effect of efficient experiments;

[0054] (7) After the experiment is completed, wipe the dust and debris on the surface, tighten the screws of the rotating handle, adjust the position, and wait to be used next time.

[0055] The drop-in high-temperature calorimeter meets the calorimetry requirements through the heat exchange between the sample cell in the high-temperature environment and the calorimeter at room temperature, and obtains accurate and reliable enthalpy and heat capacity data through the temperature changes of the calorimeter and the sample cell. To improve the working efficiency of the calorimeter, two calorimeters are used for alternating tests. To better enable the two calorimeters to work smoothly in alternating rotation, it is crucial to use the double-calorimeter rotating tray bracket of the drop-in high-temperature calorimeter.
