Description

Technical Field

[0001] The utility model relates to the technical field of 3-isochromanone production, in particular to a rectification kettle for 3-isochromanone production. Background Art

[0002] The main function of the distillation kettle for the production of 3-isochromanone is to separate and purify the mixture after the reaction. The distillation kettle heats the mixture so that different components evaporate at different temperatures and condense during the cooling process. In this way, components with different boiling points can be separated in the fractionation tower. For the production of 3-isochromanone, the distillation kettle can effectively separate the target product from the mixture and improve its purity. In the existing patent application with application number CN202220846040.8, a distillation kettle for the production of 3-isochromanone is proposed. Although it can improve the stirring speed and effect to a certain extent, speed up the material heating speed, and improve the distillation efficiency by setting a spring, a connecting plate, a mounting box, a first magnetic plate, a connecting rope, a stirring ball, a second magnetic plate and a connecting plate, its stirring blades and stirring balls can only drive the different materials in the distillation kettle to rotate in one direction when rotating. Therefore, under the action of inertial force, the rotation speeds of different materials in the distillation kettle are not much different, which makes it difficult for different materials to be mixed quickly and effectively. Ultimately, the mixing speed, heating and distillation efficiency of the materials still need to be improved, so it needs to be improved. Utility Model Content
