Description

Technical Field

[0001] This utility model relates to the field of glacial acetic acid purification technology, and in particular to a purification device for glacial acetic acid. Background Technology

[0002] Acetic acid has the molecular formula C2H4O2 and a boiling point of 118.1 degrees Celsius. Its Chinese name is acetic acid, and it is also known as glacial acetic acid. Crude acetic acid refers to acetic acid containing impurities such as formic acid, acetic anhydride, non-volatile substances, chlorides, iron, and heavy metals. Due to the highly corrosive nature of crude acetic acid, current acetic acid purification equipment is mainly made of stainless steel. It primarily employs distillation, rectification, and condensation techniques to remove impurities such as formic acid, acetic anhydride, non-volatile substances, chlorides, iron, and heavy metals, utilizing the difference in boiling points between acetic acid and these impurities for purification.

[0003] Existing patent CN202120643494.0 describes a purification device for glacial acetic acid. This device uses two semi-bevel gears that alternately mesh with a driven bevel gear to continuously rotate a first roller and a stirring fan, facilitating uniform heating of the mixture. However, in this comparative example, the mixing effect within the distillation flask is weak due to the stirring fan alone, resulting in ineffective and uniform heating of the mixture and consequently reducing the efficiency and quality of glacial acetic acid purification. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a purification device for glacial acetic acid. This device can solve the problem in the comparative example where the mixing effect of the mixture in the distillation flask is weak due to the use of only a stirring fan, which results in the mixture in the distillation flask not being heated effectively and evenly, thus reducing the efficiency and quality of glacial acetic acid purification.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0010] The inlet pipe is fixedly connected to the distillation flask and is connected to the inside of the distillation flask.

[0011] Preferably, the heating base is fixedly connected to the bottom wall of the distillation flask;

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] 1. In this glacial acetic acid purification equipment, the mixing rod rotates to stir the mixture in the distillation flask, making the mixture more uniform and the heating of the mixture in the distillation flask more uniform and efficient, thereby ensuring the efficiency and quality of glacial acetic acid purification.
