Description

Technical Field

[0001] The utility model relates to the technical field of vacuum dryers, in particular to a vacuum dryer capable of electromagnetic heating of a high-temperature inner furnace. Background Art

[0002] The vacuum drying oven is specially designed for drying heat-sensitive, easily decomposable and easily oxidized materials. It can maintain a certain vacuum degree in the working chamber during operation and can be filled with inert gas. In particular, some items with complex ingredients can also be dried quickly. An intelligent digital temperature regulator is used for temperature setting, display and control.

[0003] Patent document CN209655712U discloses a vacuum drying device for use in the graphene production process, including a drying container that can be heated by an electromagnetic heating device. One end of the drying container is mounted on a bearing on a first support rod via a rotating shaft, and the other end of the drying container is mounted on a bearing on a second support rod via a rotating shaft. The utility model uses an electromagnetic heating device to achieve the heating process of the drying container, greatly simplifying the structure of the original heating device.

[0004] When in use, the vacuum drying device proposed in the above patent document utilizes an electromagnetic heating device on the outside of the drying cylinder to heat the surface of the drying cylinder. Not only is the heat conduction speed slow, which affects the heating efficiency, but the material can only obtain heat through the inner wall of the drying cylinder. When the amount of material is large, the material accumulated inside cannot be fully heated, which affects the drying effect. Utility Model Content
