The device integrates heating, distillation, condensation and receiving design; the ceramic electric heater is adopted by the heating device so as to achieve the functions of independent power regulating of a single furnace, automatic circulation of cooling water, automatic control of distillation terminal, automatic sucking-back prevention control and the like; the integrated universal distiller is practical, convenient, saves energy, protects the environment, and solves multiple defects of a traditional device.

Description

technical field [0001] The invention relates to a pretreatment device for distillation experiments, in particular to an integrated universal distillation apparatus. Background technique [0002] Distillation is a common and important pretreatment method for laboratory separation and purification of liquid mixtures. Although the traditional distillation device can realize the basic distillation function, there are the following problems: [0003] 1. The distillation device currently used in the laboratory uses an electric furnace wire or an asbestos net embedded with an electric heating wire to directly heat the retort bottle. Due to uneven heating, the retort bottle may burst, resulting in short circuit, electric leakage, and endangering the personal safety of the operator. [0004] 2. When the distillation bottle bursts, most of the liquid will spill on the shell of the instrument or leak into the inside. If it cannot be drawn out in time, it will corrode other components ...

AI Technical Summary

Problems solved by technology

[0003] 1. The distillation device currently used in the laboratory uses an electric furnace wire or an asbestos net embedded with an electric heating wire to directly heat the retort bottle. Due to uneven heating, the retort bottle may burst, resulting in short circuit, electric leakage, and endangering the personal safety of the operator.

[0004] 2. When the distillation bottle bursts, most of the liquid will spill on the shell of the instrument or leak into the inside. If it cannot be drawn out in time, it will corrode other components of the instrument

[0005] 3. The traditional distillation device cannot distill multiple samples at the same time, and can only distill a single sample in a single furnace

[0006] 4. In the distillation process of the traditional distillation device, due to the uncontrollable heat absorbed by the distillation bottle, the heating is uneven and easy to bump, and the sample flushing occurs.

[0007] 5. The condensing and reflux device of the traditional distillation device uses tap water to condense but cannot be recycled, which wastes water resources

[0008] 6. The distillation end point of the traditional distillation device cannot be controlled, and there is no anti-suckback function, which often leads to distillation failure and affects work efficiency

However, the current technical method of using infrared induction to control the distillation end point is easily affected by the distilled droplets and misjudged the distillation end point, resulting in inaccurate control of the distillation end point and affecting the experimental results.
