Embodiment Construction

[0015] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0016] Both ends of the support pipe 14 are threaded, one end of the support pipe 14 is a sealing thread connected with the vacuum tank 1 , and the other end is threaded with the connecting piece 9 and the third nut 10 with ordinary fine thread. After the stainless steel tube 14 is connected with the vacuum tank 1 , the third sleeve 13 penetrates into the support tube 14 and then the lower cover and cylinder body of the outer protective screen 2 penetrate into the support tube 14 . At this time, the third sleeve 13 supports the outer protective screen 2 , limiting the movement and rotation of the outer protective screen 2 along the X and Y axes and the movement along the Z axis, so as to realize the complete positioning of the outer protective screen 2 . The second sleeve 12 penetrates into the support pipe...

Abstract

The invention discloses a multi-screen support device in a high-temperature adiabatic calorimeter, which belongs to the calorimetry device in calorimetry. The multi-screen support device includes a vacuum tank, 3-layer protective screen, 2-layer thermal insulation screen, protective screen support body, used to support and fix the protective screen; thermal insulation screen support body, used to support and fix the thermal insulation screen; connector, used to connect and fix A protective screen support body and a thermal insulation screen support body. The multi-screen support method in the high-temperature calorimeter solves the problems of time-consuming loading and unloading of the current high-temperature calorimeter, the coaxiality of the multi-screen assembly is not high enough, more moving parts are moved each time, and the experiment repeatability is reduced. In the method, the parts are easy to process, the assembly and disassembly efficiency is high, the operation is convenient, and the repeatability of the experiment is effectively improved.

Description

technical field [0001] The invention belongs to a calorimetric device in the field of calorimetry, and specifically relates to a mechanical support device which is convenient to disassemble and assemble, easy to process, has high assembly coaxiality and improves experiment repeatability. Background technique [0002] Heat capacity is one of the thermodynamic properties of matter. The definition of heat capacity of any system refers to the ratio of the heat added to the system to the temperature change caused by the system in any process. Mathematically process the heat capacity data obtained from experiments to obtain various standard thermodynamic functions of substances at different temperatures, such as enthalpy change, entropy change and Gibbs free energy change. The measurement of heat capacity can also obtain microscopic information such as material structure, phase transition mechanism and material purity. Heat capacity is also the basic thermophysical properties of ...
