When the device is in use, first, the nuclear magnetic tube is sleeved on the liquid guide tube 43 through the socket 421, and an appropriate amount of liquid guide tubes 43 are left vacant as the liquid outlet channel for siphon reflux; the lower end of the steam tube 32 is hermetically connected to the receiving bottle 2, the positioning frame 4 is placed upright inside the immersion cleaning chamber 3, the upper end of the immersion tube 31 is connected to the liquid outlet 12, a condensing liquid is passed into the condenser tube 1, and a cleaning solvent is put in through the liquid inlet 11. The solvent enters the immersion tube 31 through the liquid outlet 12, and a solvent is put into the receiving bottle 2. When there is an appropriate amount of solvent in both the receiving bottle 2 and the immersion tube 31, the receiving bottle 2 is heated to keep the solvent in the bottle boiling. The solvent vapor continuously condenses and refluxes into the immersion tube 31 in the condenser tube 1. As the solvent in the immersion tube 31 increases, the entire outer wall of the nuclear magnetic tube is immersed. After the solvent liquid level height exceeds the tube orifice of the nuclear magnetic tube, the inside of the nuclear magnetic tube also enters the solvent and is immersed until the solvent submerges the positioning frame 4, and all the nuclear magnetic tubes and the entire positioning frame 4 are immersed, and the grease is dissolved into the solvent. When the solvent liquid level exceeds the top end of the siphon tube 33, the solvent in the immersion tube 31 starts to be siphoned back to the receiving bottle 2 by the siphon tube 33. During this process, when the liquid level in the immersion tube 31 is lower than the positioning frame 4, the liquid in the nuclear magnetic tube starts to be siphoned back into the immersion tube 31. When the solvent in the immersion tube 31 has completed three or more complete refluxes, the nuclear magnetic tube is cleaned.This device utilizes the siphon principle and the method of steam condensation to achieve the repeated utilization of the cleaning solvent and the multiple cleaning of nuclear magnetic tubes, improving the cleaning efficiency and cleanliness of nuclear magnetic tubes.

[0028] The positioning frame 4 further includes a rotating bottom plate 45. The rotating bottom plate 45 is provided with a clamping pipe 451 and a positioning hole 452. The clamping pipe 451 is coaxially arranged with the steam pipe 32, and the clamping pipe 451 is used for clamping with the clamping hole 422. The positioning hole 452 is used for communicating with the sleeve interface 421. The clamping pipe 451 is located in the clamping hole 422. Rotate the rotating bottom plate 45 to align the positioning hole 452 with the sleeve interface 421, then put the nuclear magnetic tube on the liquid guide pipe 43, and rotate the rotating bottom plate 45 again so that the positioning hole 452 is misaligned with the sleeve interface 421. The rotating bottom plate 45 can support the nuclear magnetic tube.

[0029] A handle 46 is connected between two fixing rods 44. The positioning frame 4 can be conveniently taken out from the soaking tube 31 through the handle 46. The two ends of the handle 46 are respectively movably connected to the two fixing rods 44. The connection position of the handle 46 and the fixing rods 44 is not fixed, which is convenient for putting the handle 46 in the soaking tube 31.

[0030] The end of the siphon tube 33 facing the receiving bottle 2 is lower than the end where it communicates with the soaking tube 31. The bottom end of the siphon tube 33 is closer to the receiving bottle 2, which is convenient for discharging the solvent into the receiving bottle 2 and avoiding excessive solvent remaining on the inner wall of the steam pipe 32.

[0031] In this embodiment, the length of the liquid guide pipe 43 is greater than that of the nuclear magnetic tube, avoiding the nuclear magnetic tube sleeved on the liquid guide pipe 43 from contacting the hollow top box 41, which is convenient for the solvent to enter the inside of the nuclear magnetic tube through the top end of the nuclear magnetic tube.

[0032] There are two steam outlets 321. The two steam outlets 321 are oppositely arranged on the side wall of the steam pipe 32, which is beneficial to improving the conveying efficiency of the solvent vapor and can prevent the solvent vapor from directly flushing upward and overflowing to the outside without being fully condensed by the condenser 1.

[0033] It further includes an adapter 5. The cross-sectional area of the lower end of the adapter 5 is larger than that of its upper end. The upper end of the adapter 5 is connected to the liquid outlet 12, and the lower end of the adapter 5 is connected to the soaking tube 31. The adapter 5 is used to connect the condenser 1 and the soaking tube 31, enabling the sealed connection between the liquid outlet 12 with different diameters and the opening of the soaking tube 31.

[0034] It also includes a recovery container (not shown in the figure). A drain pipe 311 is connected to the bottom of the soaking tube 31. A piston 312 is provided on the drain pipe 311. The recovery container is used to receive the liquid discharged from the drain pipe 311. The solvent for cleaning can be n-hexane or petroleum ether. After they are used up, they need to be properly treated for recovery. Therefore, after the NMR tube is cleaned, continue to heat the receiving bottle 2. Before the solvent in the soaking tube 31 refluxes, turn on the piston 312, and drain the solvent into the recovery container through the drain pipe 311, which is the solvent recovery. After the solvent recovery is completed, stop heating the receiving bottle 2. After cooling, take out the positioning frame 4, invert it into a suitable container. After the residual solvent in the NMR tube flows out, take out the NMR tube and volatilize the remaining trace solvent, then a clean NMR tube is obtained and can be directly used for SFC measurement. If the cleaning of the next batch of NMR tubes is to be carried out, the solvent is not recovered temporarily. First, stop heating and cooling the receiving bottle 2, replace the positioning frame 4 in the device with a positioning frame 4 containing the NMR tubes to be cleaned, and continue the cleaning operation.

[0035] The condenser 1 includes a straight tube 13, a reflux tube 14 and a serpentine tube 15. The serpentine tube 15 is located inside the reflux tube 14, and the reflux tube 14 is located inside the straight tube 13. Liquid inlets 11 and outlets 12 are respectively provided at the upper and lower ends of the straight tube 13. A condensation chamber 16 is formed between the reflux tube 14 and the straight tube 13. The upper end of the serpentine tube 15 penetrates through the side walls of the reflux tube 14 and the straight tube 13, and the lower end of the serpentine tube 15 is arranged on the side wall of the reflux tube 14 and communicates with the condensation chamber 16; a condensate outlet 131 is provided on the side wall of the straight tube 13, and the condensate outlet 131 is higher than the lower end of the serpentine tube 15. Condensate is injected through the upper end of the serpentine tube 15. The condensate flows through the serpentine tube 15 for a long time. During the flowing process, the solvent vapor in the reflux tube 14 is condensed. The condensate flows out from the lower end of the serpentine tube 15 and enters the condensation chamber 16. The condensation chamber 16 filled with condensate further plays a role in condensation. When the condensate in the condensation chamber 16 reaches a certain amount, the condensate is discharged from the condensate outlet 131 into a container, and new condensate is continuously injected into the upper end of the serpentine tube 15 to ensure the condensation effect.

[0036] In other embodiments, two or more serpentine tubes can also be provided to increase the cooling area and fully condense the solvent vapor.

[0037] A wide-mouth part 17 is connected to the liquid inlet 11. The wide-mouth part 17 is used to introduce liquid and can directly receive the poured solvent, so as to quickly pour the solvent and prevent the solvent from overflowing.

[0038] In this embodiment, the liquid inlet 11 can be set as a ground joint, and other devices with extended functions, such as a vacuum pump, etc., can be connected to the liquid inlet 11.

[0039] A preferred embodiment of the present utility model further provides a nuclear magnetic tube cleaning system, which includes a heating device and the nuclear magnetic tube cleaning device of the above embodiment. The heating device is used to heat the receiving bottle 2, so that the solvent in the receiving bottle 2 becomes steam, and after being cooled by the condenser 1, it is used to clean the nuclear magnetic tube in the form of liquid. By continuously circulating the above process, the repeated use of the cleaning solvent and the multiple cleaning of the nuclear magnetic tube are realized, improving the cleaning efficiency and cleanliness of the nuclear magnetic tube.
