Background

In operations such as chemical experiments, drug testing and detection, the active ingredients of raw materials are often required to be extracted to achieve the purpose of purification or testing. In the purification, a reflux extraction method is generally used.

The reflux extraction method comprises extracting raw materials with volatile organic solvent such as ethanol, heating and distilling the extractive solution, distilling off volatile solvent, cooling, and repeatedly refluxing to the extraction container to extract raw materials.

In reflux extraction, a condenser tube is usually connected to a distillation flask, and the distillation flask is placed in a water bath for heating. The rate of vapor condensed back-flow in the condenser tube generally determines the number of times the leach is repeated per unit time. Generally, in the purification process, it takes a long time to perform the reflux leaching. Resulting in longer experimental time and lower efficiency. The condensation pipe generally comprises an outer condensation pipe and an inner condensation pipe, the outer condensation pipe and the inner condensation pipe are connected in a sealing mode, a cavity is formed between the outer condensation pipe and the inner condensation pipe, a water inlet and a water outlet are formed in the outer condensation pipe, and water flow cools the inner condensation pipe through the cavity. The general condensation inner pipe comprises a straight condensation pipe, a spherical condensation pipe, a snake-shaped condensation pipe and the like. The contact area of the spherical condensation pipe is larger than that of the straight condensation pipe, and compared with a snake-shaped condensation pipe, the manufacturing process of the spherical condensation pipe is simple, and the spherical condensation pipe can be suitable for liquids with different boiling points. However, during purification, water flow directly passes through the outer wall of the condensation inner pipe, the water flow temperature close to the outer wall of the condensation inner pipe is higher, the water flow temperature far away from the outer wall of the condensation inner pipe is lower, heat which can be taken away by water flow is less due to direct flowing of the water flow, and the condensation speed is lower. In addition, during purification, the medicine is deposited at the bottom of the reagent bottle and cannot be fully contacted with the solvent, so that the purification efficiency is low.
