Description

Technical Field

[0001] The utility model relates to the technical field of chemical experiments, in particular to a solvent extraction device. Background Art

[0002] Extraction is a method of transferring a substance from one solvent to another by utilizing the difference in solubility or distribution coefficient of a substance in two immiscible solvents. After repeated extractions, most of the substance can be extracted.

[0003] Patent document CN215195518U discloses "an extraction device for chemical laboratories, relating to the field of chemical experiment technology. The extraction device for chemical laboratories comprises a bottom plate, a fixed plate is fixedly connected to the top of the bottom plate, a solvent pump is fixedly connected to the top of the fixed plate, a first connecting pipe is fixedly connected to the outer surface of the solvent pump, and a first solenoid valve is sleeved on the outer surface of the first connecting pipe. The extraction device for chemical laboratories, through a solvent pump, a solvent bottle, a second connecting pipe, a second solenoid valve, an extraction bottle, a stirring rod and a heating tube, enables the chemicals in the extraction bottle to reach the maximum solubility in the solvent, avoids the manual hand-cranking method to make the solvent mix evenly, saves time and effort, and improves the mixing effect. Through a third connecting pipe, a third solenoid valve and a nitrogen bottle, the nitrogen in the nitrogen bottle enters the second connecting pipe through the third connecting pipe and finally enters the extraction bottle, thereby cooling the solvent and chemicals inside the extraction bottle, which is simple and efficient."

[0004] However, in the above scheme, the residual substances in the solvent and the broken chemicals are discharged into the material cup from the discharge port at the bottom of the extraction bottle. However, when collecting the solvent in the extraction bottle, the discharge port of the extraction bottle needs to be close to the mouth of the material cup. Therefore, when collecting the solvent, the operator needs to hold the material cup for collection or adjust the height of the extraction bottle for collection. If the material cup is collected by hand, the workload of the operator is increased, and the equipment is inconvenient to use. If the height of the extraction bottle is adjusted for collection, the extraction bottle is heavy and is inconvenient to move when matched with auxiliary components, thereby reducing the extraction efficiency.
