Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum furnaces, in particular to a vacuum furnace heat insulation device. Background Art
[0002] A vacuum furnace is an industrial furnace that uses a vacuum system to discharge materials in the furnace chamber. It is mainly composed of vacuum pumps, vacuum measuring devices, vacuum valves and other components that are carefully assembled. By discharging some of the materials in the furnace chamber, the pressure in the furnace chamber is less than a standard atmospheric pressure, achieving a vacuum state in the furnace chamber. The heat insulation device of the vacuum furnace, such as the graphite heat insulation cover, plays an important role in heat insulation and heat preservation inside the vacuum furnace. This device is usually used to prevent heat from dissipating too quickly and ensure that the temperature in the furnace can be maintained at a stable and appropriate level.
[0003] A common vacuum furnace insulation device is provided by adding an insulation cover inside the furnace chamber for insulation. However, in this method, during the high-temperature heating process inside the furnace body, the insulation device will expand slightly, resulting in a loose seal, causing heat to diffuse from the gap, resulting in poor insulation performance and unable to meet the working requirements of vacuum furnace insulation. Therefore, a vacuum furnace insulation device is proposed. Utility Model Content
