High-temperature carbon tube furnace

The utility model relates to the technical field of high-temperature carbon tube furnaces, in particular to a high-temperature carbon tube furnace which comprises a furnace body, a furnace cover and acooling structure, and the cooling structure comprises a communicating pipe, a filter bin, a filter element and an exhaust port. The utility model has the benefits as follows: inert gas is conveyed into the furnace body through the communicating pipe by external inert gas generation equipment, the furnace body is cooled, the explosion of the furnace body caused by too fast temperature rise is avoided, and meanwhile, the filter element is arranged, so that the normal temperature rise of the furnace body is prevented from being influenced by water vapor entering the furnace body through the filter element; the furnace body is arranged on the first hinged support in a hinged mode and driven by the driving mechanism to rotate along the hinged position of the furnace body and the first hingedsupport, so that after the
