Description

Technical Field

[0001] The invention relates to the technical field of chemical production, and in particular to a rectification device with sufficient stirring effect and compact structure. Background Art

[0002] Distillation is a process that utilizes the different volatilities of the components in a mixture, that is, the different vapor pressures of the components at the same temperature, to separate the components by heating. When applying the distillation process to separate and purify a mixture (such as chemical raw materials), a distillation device is usually used. When implementing the distillation process using a distillation device, in order to ensure the quality and effect of the distillation, the mixture needs to be continuously stirred during the process to ensure a uniform temperature distribution of the mixture, thereby avoiding uneven and incomplete purification of the material or thermal cracking and scaling. However, the existing distillation device basically only uses a rotating shaft to drive multiple layers of stirring blades to stir the mixed material. This stirring structure usually has areas with weak stirring effect between each layer of stirring blades and between the stirring blades and the inner wall of the distillation kettle of the distillation device, that is, the stirring dead corner area, which will cause uneven temperature distribution of the mixed material, making it difficult to completely separate and purify each material, or increase the time for separation and purification of each material, thereby affecting the efficiency of the distillation process; in addition, since the distillation kettle is usually heated internally by a heating component coated on the outside of the side wall, part of the mixed material close to the inner wall of the distillation kettle is more likely to undergo thermal cracking and stick to the inner wall due to its weak fluidity, thereby affecting the heating effect of the heating component and increasing energy consumption, and also increasing the difficulty of cleaning the inner wall of the distillation kettle. Therefore, how to provide a distillation device that can fully stir the mixed material inside the distillation kettle during the implementation of the distillation process has become one of the technical problems that need to be solved in this field.
