Description

Technical Field

[0001] The utility model relates to the technical field of chemical experiments, in particular to a distillation device with a protective structure. Background Art

[0002] In chemical experiments, it is often necessary to extract different components from some mixed liquids. The most commonly used method is distillation. Distillation is a thermodynamic separation process. It uses the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling-point component and then condense it to separate the entire component. It is a unit operation process that combines the two unit operations of evaporation and condensation. Compared with other separation methods, such as extraction, filtration and crystallization, it has the advantage of not requiring the use of other solvents other than the system components, thereby ensuring that no new impurities are introduced. Therefore, distillation is not only widely used in chemical experiments, but also widely used in tobacco, food, medicine, chemical industry and other industries.

[0003] Most of the existing distillation devices are complicated glass devices, which usually use electric heaters or far-infrared heating to generate water vapor. They are not only difficult to install, have a long operation time and high energy consumption, but also have major safety hazards and other technical problems. In addition, it is not convenient to quickly get out when a heating explosion occurs, which can easily cause injuries to experimenters. In addition, the heating speed of the existing distillation device is too slow to quickly heat the mixed liquid to a boiling and evaporating state. At the same time, the cooling structure of the existing distillation device only relies on the temperature difference between the air and steam temperatures to achieve cooling, and the condensation effect is poor, which is not conducive to improving the efficiency of distillation. Therefore, a distillation device with a protective structure is proposed.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The existing distillation device does not provide sufficient protection for the heating part, which can easily cause injuries to experimenters; 2. The heating speed of the existing distillation device is too slow, and the cooling effect of the condensation part is insufficient, resulting in low efficiency. Utility Model Content

[0006] An explosion-proof cover is installed on the top of the protective box, and penetrating mounting tubes are welded to the bottom, both sides and back of the protective box respectively. A blowtorch nozzle is installed at one end of the mounting tube close to the inner wall of the protective box, and a fuel bottle is sleeved on the inner wall of the other end of the mounting tube. An observation window is installed on the front of the protective box, and four sets of adjustment legs are installed on the top of the protective box.

[0007] Further preferably, a condensing spiral tube is provided inside the cooling tube, the middle part of the outer wall of the cooling tube is sleeved on the inner wall of the stabilizing ring, an adjusting shaft passes through the bottom of the stabilizing ring, a support rod is connected to the bottom of the stabilizing ring, the support rod is configured as a height-adjustable structure, and the top of the support rod is rotatably connected to the stabilizing ring through the adjusting shaft.

[0008] Further preferably, a coolant is filled between the inner wall of the cooling tube and the outer wall of the condensing spiral tube.

[0009] Further preferably, the explosion-proof cover forms an opening and closing structure with the top opening of the protection box through a hinge, and the surface of the observation window is inlaid with transparent tempered glass.

[0011] Further preferably, a blocking cap is provided on the inner wall of the top pipe opening of the three-way pipe, a plurality of penetrating air holes are provided on the surface of the explosion-proof cover, and the protective box forms a lifting structure by adjusting legs.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

Together with the explosion-proof cover on the top, splashing caused by an accidental explosion of the flask can be prevented, thereby protecting the experimenter from injury. Furthermore, the plurality of heating torch nozzles can heat the flask at the same time, so that the flask is heated evenly, thereby reducing the risk of flask explosion.
