Description

Technical Field

[0001] The utility model relates to the technical field of chemical experiment glassware, in particular to an anti-violation rotary evaporator. Background Art

[0002] In the process of chemical organic synthesis, food analysis and testing, the extraction, separation and purification of target compounds often require the distillation and concentration of large volumes of organic solutions. Rotary evaporators, especially vacuum rotary evaporators, are commonly used equipment to achieve liquid distillation and concentration. The solvent in the distillation flask is heated with a heating bath, and the rotary evaporator rotates at the same time, so that the material forms a large-area thin film on the flask wall, which evaporates efficiently.

[0003] After searching, it was found that the announcement number was CN215585483U, and the name was a rotary evaporator and an anti-violent rotary evaporator. The application proposed that the connection between the existing rotary evaporator and the rotary evaporator is mainly carried out by ground mouth, plastic buckle or (ground mouth + plastic buckle). When the rotary evaporator is installed and removed, it may accidentally fall off due to the disappearance of vacuum negative pressure or gravity, causing the relevant chemical experiments to be destroyed. When the mouth of the rotary evaporator has small cracks or slight damage during use and cleaning, the ground mouth and the plastic buckle cannot achieve a sealed connection between the rotary evaporator and the rotary evaporator, so that the rotary evaporator cannot be discarded due to normal use. The problem of high loss rate is solved by providing an externally threaded inner ground mouth bottle mouth and a matching internally threaded sealing cover, the connection is stable and reliable, avoiding the disappearance of vacuum negative pressure or gravity during the installation and removal of the rotary evaporator. The invention also aims to prevent the accidental falling off due to the following reasons, thus causing the relevant chemical experiments to be abandoned. In addition, the invention also aims to prevent the ground mouth and the plastic buckle from being unable to achieve the sealed connection between the rotary evaporator and the rotary evaporator when the mouth of the rotary evaporator has fine cracks or slight damage during use and cleaning, and the rotary evaporator is discarded because it cannot be used normally. When the liquid in the rotary evaporator boils violently, the addition of organic solvent in the liquid addition funnel can effectively prevent the boiling bubbles from contaminating the interface of the rotary evaporator. However, the application avoids violent boiling by adding organic solvent. Organic solvent is a consumable, which increases the investment in consumables. The organic solvent needs to be separated later, which is more troublesome to use. In addition, the existing rotary evaporator needs to be modified, especially the external thread is set. Since the wall thickness of the rotary evaporator is relatively small, the external thread is difficult to be integrally formed, which increases the production and use costs. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
