[0022] Referring to the attached Figures 1-3 , a huperzine A reaction solution sampling device, comprising a sampling tube 1. The sampling tube 1 is in an L shape. The vertical part of the sampling tube 1 is inserted into the reaction kettle. A collection tube 3 is communicated with the port of the horizontal part of the sampling tube 1, and a first valve 2 is assembled on the side wall. The other end of the collection tube 3 is communicated with an airbag 4. A first connecting tube 5 is communicated with the side wall of the collection tube 3. The port of the first connecting tube 5 is vertically downward, and a second valve 6 is assembled on the side wall.

[0023] In this embodiment, the vertical part of the sampling tube 1 is inserted into the reaction kettle, then the first valve 2 is closed and the second valve 6 is opened. Then, the airbag 4 is pressed, and the air in the airbag 4 is discharged to the outside through the first connecting pipe 5. Next, the first valve 2 is opened, the second valve 6 is closed, and then the airbag 4 is released. The airbag 4 is in a negative pressure state, and the huperzine A reaction solution in the reaction kettle is sucked into the collection tube 3. Finally, the first valve 2 is closed again and the second valve 6 is opened. At this time, when the airbag 4 is pressed, the huperzine A reaction solution in the collection tube 3 can be discharged through the first connecting pipe 5 for sampling. Thus, sampling can be achieved without opening the reaction kettle cover. The whole sampling process is simple and fast, reducing the labor intensity and improving the work efficiency at the same time.

[0024] A second connecting pipe 7 is also communicated and arranged on the side wall of the collection tube 3. The port of the second connecting pipe 7 faces vertically upward, and a third valve 8 is assembled on the side wall.

[0025] In this embodiment, after the airbag 4 is in a negative pressure state and sucks the huperzine A reaction solution in the reaction kettle into the collection tube 3, the first valve 2 is closed, and the second valve 6 and the third valve 8 are opened. The outside air enters the collection tube 3 through the second connecting pipe 7, and the huperzine A reaction solution in the collection tube 3 can be directly discharged through the first connecting pipe 5 for sampling. Compared with the above embodiment, the sampling and liquid discharging by pressing the airbag 4 are more thorough.

[0026] A fixing ring 9 is arranged on the horizontal part of the sampling tube 1. Two connecting rods 10 are fixedly installed on the fixing ring 9, and the other ends are respectively fixedly installed on the first connecting pipe 5 and the second connecting pipe 7. Through the support of the connecting rods 10, the load of the collection tube 3 can be reduced.

[0027] It further includes a threaded sleeve 11 that matches the feed inlet of the reaction kettle. A limit sleeve 12 is fixedly installed on the outside of the threaded sleeve 11, and a fixing sleeve 13 is arranged inside. The fixing sleeve 13 is sleeved on the vertical part of the sampling tube 1.

[0028] A threaded hole 131 is opened on the fixing sleeve 13. The threaded hole 131 communicates with the inside of the fixing sleeve 13, and a positioning bolt 14 is threadedly installed. The end of the positioning bolt 14 abuts against the side wall of the vertical part of the sampling tube 1.

[0029] In this embodiment, after the threaded sleeve 11 is aligned with the feed inlet of the reaction kettle, hold the limit sleeve 12 and rotate it until the limit sleeve 12 abuts against the reaction kettle, then the connection with the reaction kettle is completed. The vertical part of the sampling tube 1 can slide in the fixing sleeve 13 and is locked by rotating the positioning bolt 14, so that sampling can be carried out at different depths inside the reaction kettle.

[0030] The above-described embodiments merely represent certain implementation manners of the present utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.

[0031] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and overly complex technical content in this field, the above content of this application does not necessarily constitute prior art.
