Description

A temperature-controlled distillation device

technical field

The utility model relates to the field of distillation devices, in particular to a temperature-controlled distillation device.

Background technique

In the distillation experiment, the temperature control determines the success or failure of the experiment and the purity of the distillation components, so how to accurately control the distillation temperature is the main technical point of the experiment operation. In the specific distillation experiment operation, the main heating tool is still the alcohol lamp, and the temperature control of the distillation bottle heating mainly depends on adjusting the distance between the alcohol lamp and the bottom of the bottle (the temperature of the outer flame, the middle flame, and the inner flame of the flame are different), and When the temperature is too high, quickly remove the alcohol lamp to control, which will bring the following problems to the operator:

First of all, the adjustment and movement of the alcohol lamp in the experiment required direct contact with the alcohol lamp by hand, which not only had a certain operational risk, but also made it difficult to achieve fine adjustment of the height by hand, resulting in large errors.

Secondly, in the distillation experiment, the existing fixing devices mainly use iron stands, which can only fix the distillation flask, and there is no corresponding mechanism for the placement of the alcohol lamp, which makes the experimenter only after determining a reasonable burning distance. Finding other items to place on the mat not only brings trouble to the experimenter, but also makes it difficult to match the height, which is not conducive to accurate control of the burning distance.

In addition to temperature control, it is often difficult to control the height of the distillation flask and receiving flask during the assembly of the distillation experimental apparatus. Since the relative positions of the distillation flask, condenser tube and receiving flask are fixed after the installation of the experimental device, it is difficult to take into account the height of both ends at the same time. Once the height of the receiving flask is unreasonable and cannot fall on the experimental bench, it is necessary to adjust the height of the distillation flask ,very troublesome.
