[0044] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0045] Please refer to Figure 1 The specific implementation of the utility model relates to a corrosion inhibitor rapid extraction device, comprising:

[0046] Bracket 1;

[0047] A heating device 2, wherein the heating device 2 is connected to the bracket 1;

[0048] A flask 3, wherein the flask 3 is arranged on the upper part of the heating device 2;

[0049] A condenser 4, wherein the condenser 4 is connected to the support 1 and is located above the flask 3;

[0050] A liquid storage container 5, the liquid storage container 5 is connected to the bracket 1, the liquid storage container 5 is located directly below the condenser 4, the liquid storage container 5 is located above the flask 3, and the lower end of the condenser 4 is connected to the upper part of the liquid storage container 5 through the first connecting pipe 6;

[0051] a second connecting tube 7, wherein the lower end of the second connecting tube 7 is connected to the mouth of the flask 3, and the upper end of the second connecting tube 7 is connected to the first connecting tube 6;

[0052] A liquid-conducting main pipe 8, the upper end of which is connected to the lower end of the liquid storage container 5;

[0053] A first stop valve 9, wherein the first stop valve 9 is connected to the liquid conducting main pipe 8;

[0054] Liquid guiding branch pipes 10, the upper ends of the plurality of liquid guiding branch pipes 10 are connected to the lower end of the liquid guiding main pipe 8;

[0055] A second stop valve 11, wherein the second stop valve 11 is connected to the liquid conducting branch pipe 10;

[0056] A reflux container 12, wherein a plurality of the reflux containers 12 are detachably connected to the bracket 1, the plurality of the reflux containers 12 are located at the same height, the reflux container 12 is located above the flask 3, the reflux container 12 is located below the liquid storage container 5, and a reflux siphon 121 is connected to the side of the reflux container 12;

[0058] The second hose 14 has an upper end connected to the reflux siphon 121 , and a lower end connected to the flask 3 .

[0059] In the above implementation mode, refer to Figure 1, the number of reflux containers 12 is 5, the samples to be extracted such as pepper, tea and peel are placed in each reflux container 12, the extraction solvent is put into the flask 3, the flask 3 is heated by the heating device 2, the solvent is volatilized, and reaches the condenser 4 through the second connecting pipe 7 and the first connecting pipe 6. After condensation and reflux through the condenser 4, it is stored in the liquid storage container 5. At this time, the first stop valve 9 and the second stop valve 11 are opened, and the condensed solvent flows into each reflux container 12 through each liquid guide branch pipe 10, so that the sample is immersed in the solvent. When the liquid level in the reflux container 12 is higher than the height of the reflux siphon 121, under the action of water pressure, the solvent cooperates with the extract to flow back to the flask 3 through the reflux siphon 121, and the solvent in the flask 3 continues to evaporate.
