Description

Technical Field

[0001] The utility model relates to the technical field of rotary evaporators, in particular to an automatic bottle loading mechanism of a rotary evaporator. Background Art

[0002] Rotary evaporator, also known as rotary evaporator, is an evaporation instrument widely used in laboratories. It is mainly composed of a motor, a distillation flask, a heating pot, a condenser and other parts. It is mainly used for continuous distillation of volatile solvents under reduced pressure conditions. Its working principle is to use a motor to drive the distillation flask to rotate, so that the liquid sample forms a layer of liquid film on the inner surface of the distillation flask, thereby increasing the heating area and increasing the evaporation rate. At the same time, rotation can also effectively suppress the boiling of the sample and avoid the addition of zeolite.

[0003] In the process of using a rotary evaporator, a key step is to install the distillation flask. However, this process currently often relies on manual operation, which not only makes it difficult to quickly and accurately position the distillation flask, but also greatly reduces the installation speed of the distillation flask. What is more inconvenient is that the existing rotary evaporator usually uses a threaded connection to fix the distillation flask, which is particularly inconvenient when the distillation flask needs to be quickly separated, thereby reducing the overall convenience and use efficiency of the rotary evaporator. In order to improve operational efficiency and convenience, it is necessary to improve the installation and fixing method of the distillation flask of the rotary evaporator.

[0004] Therefore, it is necessary to provide a new automatic bottle loading mechanism of a rotary evaporator to solve the above-mentioned technical problems. Utility Model Content
