Abstract

The invention relates to the technical field of medicine production, in particular to a distillation furnace device for drug intermediates. The distillation furnace device comprises a bottom plate, wherein a distillation furnace main body is mounted on one side of the upper surface of the bottom plate, a driving motor is fixedly mounted on the surface of one end of the distillation furnace main body, a first stirring mechanism is arranged at the output end of the driving motor and located in the distillation furnace main body, a second stirring mechanism is arranged at the other end of the first stirring mechanism and located at the end, which is away from the driving motor, of the distillation furnace main body, and a cooling mechanism is arranged on the upper surface of the bottom plate and located on one side of the distillation furnace main body. By arranging the first stirring mechanism and the second stirring mechanism, internal materials can be longitudinally and transversely stirred at the same time, so that the mobility of the materials in the distillation furnace is higher, the materials are heated more uniformly, distillation is more sufficient, and the distillation efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical production, in particular to a distillation furnace device for pharmaceutical intermediates. Background technique [0002] Pharmaceutical intermediates are chemical raw materials used in the synthesis of some pharmaceuticals. During the production of pharmaceuticals, they need to be processed through multiple processes of pharmaceutical intermediates. During the processing of pharmaceutical intermediates, distillation is required to decompose the internal components. It is convenient for subsequent processing, but in the distillation process of the existing distillation furnace, the drug intermediate will be heated unevenly, which will cause insufficient distillation, affect the processing quality of the drug, and the distillation efficiency is low, and the use is more troublesome. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the...
