Description

Technical Field

[0001] The utility model relates to the field of high vacuum distillation kettles, in particular to a high vacuum distillation system. Background Art

[0002] Vacuum distillation, also known as "reduced pressure distillation", is one of the distillation methods. It is carried out under reduced pressure. It is generally used to separate substances that are easy to decompose or polymerize when heated to boiling under normal pressure or combined with other distillation methods (such as steam distillation) to reduce the distillation temperature. It is commonly used in chemical, petroleum and other industries. The distillation method is a separation method that utilizes the differences in certain physical properties of the components of the distillate, and the vacuum distillation kettle is a kettle used for vacuum distillation. It is mainly designed to solve the problem that the existing distillation kettle needs to be intermittently inspected and cleaned when the material contains solids and high-boiling-point substances during the production process. At present, when the vacuum distillation kettle is used, when the distillation liquid inside the vacuum distillation kettle is heated to the boiling point, a large number of bubbles will be violently generated inside the distillation liquid. These bubbles will burst at the liquid surface. When the bubbles burst, some distillation liquid will be splashed, causing these distillation liquids to be adsorbed on the inner wall of the vacuum distillation kettle heating dish. Because the inner wall of the vacuum distillation kettle heating dish is at a high temperature under the action of the heating plate, and the amount of distillation liquid is small, the non-target substances of the distillation liquid are easily reached The boiling point, non-target steam is generated, and the purity of the collected product is reduced.

The floating enclosure 18 is fixedly connected to the anti-splashing mesh plate 17;

[0026] A waste discharge pipe 14 is arranged at the lower end of the high vacuum distillation kettle body 1. The high vacuum distillation kettle body 1 is welded to the waste discharge pipe 14. A spiral conveying bracket 13 is installed at the lower end of the outside of the rotating shaft 5.
