High-vacuum-degree film evaporator

The utility model discloses a high-vacuum-degree film evaporator, which relates to the technical field of film evaporators and is characterized in that a vertical cylindrical condensation bin is adopted, a scraping frame comprising a rotating shaft and a plurality of scraping rods is arranged on the inner side of the condensation bin, and fan blades drive the scraping rods to rotate under the impact action of materials discharged by a film evaporator body; a scraping rod automatically scrapes oil wax condensed on the inner wall of the condensation bin, and cleaning is convenient; the oil wax brought out from the outlet of the film evaporator body is condensed to prevent the oil wax from entering a vacuum unit to damage equipment, so that the high vacuum degree required by the film evaporator is favorably improved and maintained, and meanwhile, the Fischer-Tropsch refined wax oil content is reduced; by means of the structure, materials can make more sufficient contact with the inner wall of the condensation bi
