[0002] In the process of chemical experiments, biological experiments and the process of transferring liquid solvents in factories, it is necessary to frequently absorb liquid solvents. During this process, some air (moisture, oxygen, etc.) will inevitably be mixed into liquid solvents, which will affect itself. The degree of purification, which in turn affects the accuracy of specific experimental results or the quality of finished products
In the prior art, there is no equipment applicable to the purification and extraction of relevant experimental solvents

[0032] Finally, the present invention also discloses an implementation method suitable for the experimental solvent purification and extraction system, which includes the following steps:
[0033] a. Start the vacuum generating device 4, then adjust the four-position four-way valve to connect it with the liquid-taking bottle 3, and extract the air in the liquid-taking bottle 3 to the set vacuum degree Pv1;
[0034] b. Operate the four-position four-way valve to connect the inert gas source 5 with the liquid-taking bottle 3, so that the inert gas is filled with the liquid-taking bottle;
[0035] c. Continue to operate the four-position four-way valve, connect the vacuum generating device 4 with the liquid extraction bottle 3, and extract the inert gas in the liquid extraction bottle 3 to the set vacuum value Pv2;
[0036] d. Repeat steps a, b, and c;
[0037] e. Continue to operate the four-position four-way valve, connect the liquid-taking bottle 3 with the solvent source 1, ...

The invention relates to an experimental solvent purifying and drawing system which comprises a solvent source for holding an experimental solvent, a reversing valve, a liquid taking bottle, a vacuumgenerating device and an inert gas source, wherein the reversing valve is a four-position four-way valve, and the three inlets of the four-position four-way valve are separately connected to the solvent source, the vacuum generating device and the inert gas source one by one and the outlet of the four-position four-way valve is connected to the liquid taking bottle. By replacing air in the liquidtaking bottle by means of inert gas till oxygen and water in the liquid taking bottle meet a standard demand while introducing the experiment solvent, the probability that water, oxygen and the like in the drawing process are blended into the experimental solvent is reduced, so that the experimental solvent purifying and drawing process is achieved. It is noted that the applicable precondition ofthe technical scheme is that the experimental solvent stored in a solvent source is purified (water and oxygen and the like meet the standard). In addition, the invention also discloses an implementing method matched with the experimental solvent purifying and drawing system.
Description
technical field [0001] The invention relates to the technical field of experimental solvent extraction, in particular to an experimental solvent purification extraction system for preventing water and oxygen from mixing in, and also relates to an implementation method. Background technique [0002] In the process of chemical experiments, biological experiments and the process of transferring liquid solvents in factories, it is necessary to frequently absorb liquid solvents. During this process, some air (moisture, oxygen, etc.) will inevitably be mixed into liquid solvents, which will affect itself. The degree of purification will affect the accuracy of specific experimental results or the quality of finished products. In the prior art, there is no equipment applicable to the purification and extraction of relevant experimental solvents. Therefore, it is urgent for technicians to solve the above problems.
