Description

Technical Field

[0001] The utility model relates to the field of cleaning devices, in particular to a simple device for cleaning nuclear magnetic tubes with high efficiency and durability. Background Art

[0002] In chemical research, nuclear magnetic resonance technology is a widely used testing technology that provides very important information for the structural analysis of compounds. During the test, the sample needs to be placed in a nuclear magnetic resonance tube and the tube is placed in a magnet for detection. The cleaning of the nuclear magnetic resonance tube is a very important part. If the cleaning is not thorough or the cleaning method is improper, it will affect the experimental results.

[0003] There are currently four main methods for cleaning NMR tubes:

[0004] 1. Directly insert a cotton swab with cleaning solution into the NMR tube for cleaning. This method is relatively clean, but it is time-consuming and labor-intensive, and it is very easy to scratch the NMR tube.

[0005] 2. Put the NMR tube into the cleaning solution and clean it in an ultrasonic cleaner. The advantage of this method is that it does not require manpower, but the NMR tube is easy to break, resulting in a shortened service life.

[0006] 3. Put a dozen NMR tubes with the solution poured out into a beaker, add 80% of the cleaning solution, pour the cleaning solution into the recovery bottle, hold the dozen NMR tubes and shake them on the ground, repeat the action of adding cleaning solution and shaking them about three times. This method is fast, but laborious, and the cleaning solution may splash to other places when shaking, causing pollution. In addition, if too much force is used, the NMR tubes can easily fall out of your hands and fall to the ground, causing them to break.

[0007] 4. Use a dedicated NMR tube cleaner. If there are many NMR tubes, you can use a five-tube cleaner. If there are few NMR tubes, you can use a single-tube cleaner. Using a dedicated cleaner has a fast cleaning speed and good cleaning quality, but the disadvantage is that it is expensive and not suitable for use in ordinary laboratories. Utility Model Content

[0009] The technical solution of the utility model is a simple device for cleaning nuclear magnetic tubes with high efficiency and durability, comprising a suction flask with a top bottle mouth and a side connecting port, a Büchner funnel sealed at the top bottle mouth of the suction flask, a plurality of hollow tubes which are inserted through the seal on the Büchner funnel and whose bottom and top ends are respectively located on the inner and outer sides of the suction flask, and a vacuum pump which is connected to the side connecting port of the suction flask, the Büchner funnel having a liquid storage tank with an opening facing upward, a plurality of through holes being provided at the bottom of the liquid storage tank, and the hollow tubes are inserted through the seal at the through holes.

[0010] Preferably, the hollow tubes are distributed vertically.

[0011] Preferably, the length of the hollow tube above the bottom of the liquid storage tank is greater than the length of the nuclear magnetic resonance tube to be cleaned.

[0012] Preferably, an epoxy sealant layer is passed between the bottom end of the through hole of the Buchner funnel and the hollow tube.

[0013] Preferably, the vacuum pump is connected to the side connecting port of the suction flask through a connecting pipe.

[0014] Preferably, a sealing plug which is sealingly connected to the Buchner funnel is installed at the bottom end of the suction filtration bottle.

[0015] Compared with the prior art, the utility model has the following beneficial technical effects:

[0016] 1. This cleaning device can automatically clean the nuclear magnetic tube mounted on the hollow tube by pressurizing with a vacuum pump, and has good cleaning effect, saving time and labor.

[0017] 2. This cleaning device uses the solubility and impact force of the cleaning liquid to clean the NMR tube. The cleaning process is safe and reliable, with little damage to the NMR tube, which can avoid damage to the NMR tube during the cleaning process and ensure that the NMR tube has a long service life. The cleaning speed is fast, the effect is good, and the cleaning process is simple and reliable.

[0018] 3. When using this cleaning device for cleaning, the cleaning liquid flows into the suction filter bottle along the opening at the top of the hollow tube, which can prevent the cleaning liquid from splashing and avoid contamination.

[0019] 4. The hollow tube, Buchner funnel, suction flask and sealing plug used in this cleaning device are all very common equipment in the laboratory. Therefore, compared with special cleaning devices, this cleaning device has low cost, easy assembly and convenient use, and can be installed when used and disassembled after use.

[0023] Embodiment 1

[0024] like Figure 1 and Figure 2 As shown, a simple device for cleaning nuclear magnetic tubes with high efficiency and durability proposed in this embodiment includes a hollow tube 2, a Buchner funnel 3, a suction bottle 4 and a vacuum pump 6. The suction bottle 4 has a top bottle mouth and a side connecting port. The Buchner funnel 3 is sealed at the top bottle mouth of the suction bottle 4. The Buchner funnel 3 has a liquid storage tank with an opening facing upward, and a plurality of through holes 301 are arranged at the bottom of the liquid storage tank. A plurality of hollow tubes 2 vertically penetrate the through holes 301 sealed and inserted on the Buchner funnel 3. The number of hollow tubes 2 is less than or equal to the number of through holes. For the through holes without hollow tubes 2, it is necessary to perform a blocking treatment. The bottom and top of the hollow tube 2 are respectively located on the inside and outside of the suction bottle 4. The vacuum pump 6 is connected to the side connecting port of the suction bottle 4.

[0025] The length of the hollow tube 2 located above the bottom of the liquid storage tank is greater than the length of the NMR tube 1 to be cleaned, for example, the greater length may be 1 cm.

[0026] This embodiment has a simple structure, is easy to use, has a low cost, a fast cleaning speed, a good effect, will not scratch the nuclear magnetic tube, will not cause the nuclear magnetic tube to break, and can extend the service life of the nuclear magnetic tube. When in use, add cleaning liquid to the liquid storage tank of the Buchner funnel 3, and place the nuclear magnetic tube 1 to be cleaned upside down on the hollow tube 2, and the bottom end of the nuclear magnetic tube 1 to be cleaned is completely immersed in the cleaning liquid. Start the vacuum pump 6, which creates a negative pressure in the suction filtration bottle 4. The cleaning liquid in the liquid storage tank will rise upward along the inner wall of the nuclear magnetic tube 1 to be cleaned to the bottom of the nuclear magnetic tube 1 to be cleaned (the top when inverted) under the action of the pressure difference, and use the solubility and pressure of the cleaning liquid to effectively impact the inner wall of the nuclear magnetic tube 1 to be cleaned. Then the cleaning liquid flows downward from the inside of the hollow tube 2 to the suction filtration bottle 4 through the area between the bottom of the nuclear magnetic tube 1 to be cleaned and the top of the hollow tube 2. When cleaning the cleaning liquid, the connection between the vacuum pump 6 and the suction filtration bottle 4 is released, and the cleaning liquid in the suction filtration bottle 4 is poured out through the side connection port.

[0027] Embodiment 2

[0028] like Figure 1 and Figure 2 As shown, this embodiment proposes a simple device for cleaning nuclear magnetic tubes with high efficiency and durability. Compared with the first embodiment, in this embodiment, an epoxy sealant is passed between the bottom end of the through hole 301 of the Büchner funnel 3 and the hollow tube 2, thereby ensuring the stability of the hollow tube 2 and preventing the cleaning liquid from leaking from the through hole 301 of the Büchner funnel 3.

[0029] The vacuum pump 6 is connected to the side connecting port of the suction bottle 4 through the connecting pipe 5, so that negative air pressure can be created in the suction bottle 4.

[0030] A sealing plug 7 is installed at the bottom end of the suction filtration bottle 4 and is sealed with the Buchner funnel 3 , thereby ensuring a sealed connection between the Buchner funnel 3 and the suction filtration bottle 4 .

[0031] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
