Description

Technical Field

[0001] This utility model relates to the field of calorimeter furnace technology, and in particular to an adiabatic accelerated calorimeter furnace. Background Technology

[0002] Adiabatic accelerated calorimeters are based on the principle of heat balance. They apply heat energy to the sample through a heating device to stimulate internal thermal reactions and monitor and record the sample's temperature change curve. During testing, the sample is placed in a controlled temperature environment. The instrument's furnace heater promptly replenishes the heat loss caused by the temperature difference between the sample and its surrounding environment, thus maintaining the adiabatic testing environment. By analyzing the temperature change curve, various thermal performance parameters, such as heat capacity, thermal conductivity, and exothermic peak value, can be obtained.

[0003] In existing adiabatic accelerated calorimeters, the furnace body usually has thermal inertia, and there is usually heat dissipation between the reaction system and the furnace chamber, which usually prevents the entire system from reaching a completely adiabatic state. This can easily affect the thermodynamic and kinetic calculation results of thermal decomposition. Therefore, a new type of adiabatic accelerated calorimeter furnace body is needed to solve the above problems. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

A furnace opening 17 is provided on the surface of the calorimeter furnace body 1, and a ring plate 18 is fixedly connected to the surface of the calorimeter furnace body 1 at the furnace opening 17. A furnace cover 20 is embedded inside the ring plate 18, which can serve as a feeding device.

[0022] Example 2, as Figure 1-3 As shown, support legs 2 are fixedly connected at equal intervals to the bottom and near the edge of the calorimeter furnace body 1. The bottom of the support legs 2 is trapezoidal, which can support the bottom of the calorimeter furnace body 1. A placement plate 4 is fixedly connected to the inner wall of the bottom of the calorimeter furnace body 1.
