High-temperature calorimeter sample storing and taking device

Abstract

The invention relates to calorimetric devices of calorimetry, in particular to a high-temperature calorimeter sample storing and taking device. The device comprises a sample pool used for storing a sample and a crucible clamp used for grabbing the sample; the crucible clamp comprises a crucible clamp core and a clamp core sleeve module arranged at the outer side of the crucible clamp core in a sleeving mode, wherein the crucible clamp core and the clamp core sleeve module can move relative to each other in the axial direction, and one end of the crucible clamp core is provided with a crucibleclamp jaw used for grabbing the sample pool. The sample pool comprises a sample pool main body and a sample pool bottle cap used for sealing the sample pool main body, wherein the top of the sample pool bottle cap is provided with a grabbing part used for grabbing of the crucible clamp. According to the device, the sample pool is compact in structure and fine in design so that the leakage of the sample in the sample pool cannot occur under the internal and external pressure difference of 100 MPa, and the excellent sealing performance is achieved; and the sample pool can be assembled and disassembled through the crucible clamp so that an operator can conveniently replace the sample.

Description

technical field [0001] The invention relates to a calorimetric device in calorimetry, in particular to a device for storing and taking out samples of a high-temperature calorimeter. Background technique [0002] Heat capacity is the sum of the energy contributions of the internal lattice, electrons and other moving forms of the material system, and is a basic thermophysical parameter of matter.
