TECHNICAL FIELD
[0001] The utility model relates to distillation equipment technical field, concretely to a distillation kettle of high discharge efficiency. BACKGROUND
[0002] The distillation kettle is a device specially used for distillation operation in chemical production, and its core function is to separate each component in a mixture by using the difference in boiling point. The device has been widely used in many fields such as petroleum, chemical industry, pharmaceutical and spice. Its design and operation are based on a basic principle: during the heating process, due to the difference in volatility (i.e. the difference in boiling point) of each component in the liquid mixture, low-boiling-point substances (i.e. volatile components) will first change from liquid phase to gas phase. Then, these gas phase substances are collected through the condensation process, thereby realizing effective separation of components. In order to further improve the distillation efficiency, a stirring device is usually installed in the distillation kettle, which can stir the internal liquid to be distilled during the distillation process, thereby enhancing the distillation effect and improving the distillation efficiency.
[0003] At present, the patent with the publication number CN218572842U discloses a multi-stage distillation purification device for silane coupling agent production line, which comprises a distillation kettle, a stirring shaft and a driving motor, and further comprises a stirring mechanism composed of a fan plate, an inclined plate, a middle rod, a vertical plate and a ring paddle. The tank body of the distillation kettle is inserted into the installation of the rotatable stirring shaft through the hole body in the central part, and the power shaft head of the stirring shaft extending out of the top end of the distillation kettle is nested and connected with the power output end of the driving motor to obtain power. The driving motor and the top end of the distillation kettle are locked by bolts. The optimization and improvement of the stirring structure are carried out at the distillation kettle of the multi-stage distillation purification production line for silane coupling agent. When the silane coupling agent is stirred and mixed in the distillation kettle for heating and distillation, the multi-stage stirring structure of the stirring mechanism forms a stirring area when the layers are formed, thereby stirring and mixing the silane coupling agent raw materials in a large area and in a hierarchical manner, realizing high efficiency stirring of the silane coupling agent during heating and distillation in the distillation kettle.
[0004] However, the distillation kettle in the above-mentioned technology still has the following problems: although the internal part of the distillation kettle is stirred by the stirring mechanism, thereby realizing high efficiency of the distillation effect, but as the distillation continues, the impurities that may exist in the liquid in the distillation kettle will continuously precipitate, and then adhere to the inner wall of the distillation kettle to form a heat insulation layer, resulting in uneven heating of the internal part of the distillation kettle, and then affecting the distillation efficiency of the distillation kettle.
