Technical Field

[0001] The utility model relates to the technical field of vacuum furnaces, in particular to a double-layer structure vacuum furnace shell. Background Art

[0002] A vacuum furnace is a new type of heat treatment device that combines vacuum and heat treatment. Its heating temperature can rise to more than one thousand degrees, making it an ideal device for atmosphere protection sintering and atmosphere reduction in universities, research institutes, industrial and mining enterprises. The utility model patent with the publication number CN208736171U discloses a box-type double-layer shell vacuum furnace, which includes a furnace body with heat preservation blocks embedded in the middle and a box-type outer shell. One end of the furnace body is connected to a vacuum unit through an exhaust pipe, and the other end cover is provided with an openable furnace door. At the same time, a heat insulation device is provided at one end of the furnace chamber of the furnace body close to the furnace door. The furnace door is of a hollow structure, and the hollow structure is provided with a water inlet pipe and a water outlet pipe respectively connected to a water cooling circulation device. A guide vane is also provided on the hollow structure of the furnace door between the water inlet pipe and the water outlet pipe. The vacuum furnace of this utility model adopts a double-layer shell structure, with heat insulation materials added outside the working chamber and then installed in the outer shell of the furnace body, improving the heat preservation and heat insulation performance of the vacuum furnace. The water cooling device in the furnace door further cools the furnace door to keep the external temperature stable. An additional heat insulation device is also added in the furnace chamber to prevent the external temperature from overheating when the vacuum furnace is working. However, this vacuum furnace does not have a quick material taking mechanism, resulting in the need for operators to reach into the furnace body to pick up materials, and the high temperature inside the furnace body is likely to scald the operators. Therefore, this vacuum furnace still has deficiencies and needs to be improved. Summary of the Utility Model
