Description

Technical Field

[0001] The utility model relates to the technical field of detection of deuterium isotope abundance in water samples, in particular to a storage tank for detecting deuterium isotope abundance in deuterium gas. Background Art

[0002] The existing method for determining deuterium isotope in water is the gas isotope mass spectrometry method. Usually, the pretreatment requires reacting water in the sample with metal at high temperature to generate deuterium-labeled hydrogen gas, and detecting the deuterium isotope abundance by a gas isotope mass spectrometer.

[0003] Chinese Patent Publication No. CN112305058A, published on February 2, 2021, discloses a method for determining deuterium isotope abundance in water samples, including the following steps: (1) Put magnesium strips into a reaction container, seal it, evacuate it, and then inject the water sample into the reaction container; (2) Heat the reaction container to make the magnesium strips react with the water sample to generate deuterium-labeled hydrogen gas; (3) After the reaction container cools to room temperature, suck the deuterium-labeled hydrogen gas in the reaction container and inject it into the gas isotope mass spectrometer to detect and record the relative intensities of mass numbers 2, 3, and 4, that is, calculate the deuterium isotope abundance in the water sample.

[0004] Most of the existing methods for determining deuterium isotope abundance in water samples are based on storage tanks, and the storage tanks use common sample bottles. In the specific implementation process, the stability of the storage tank is poor. During the processes of evacuation, magnesium strip placement, and water injection, the storage tank is prone to deviation or even tipping. Therefore, it is urgent to propose a corresponding storage tank for detecting deuterium isotope abundance to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to propose a storage tank for detecting deuterium isotope abundance in order to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A storage tank for detecting deuterium isotope abundance includes a tank body and a cover body. Both horizontal sides of the cover body are fixedly connected with support frames, and a fixing component for fixedly connecting the tank body and the support frames is arranged between the support frames and the tank body. The bottom of the support frame is fixedly connected with a base, and a suction cup is integrated at the bottom of the base. A vacuum pumping interface, a water injection port, and a magnesium strip feeding port are integrated at the top of the cover body.

[0008] Preferably, a support plate is fixedly connected between the two support frames, and the top of the support plate abuts against the bottom of the tank body.

[0009] Preferably, a vertical plate is fixedly connected to the top of the support plate, and the vertical plate is fixedly connected to the support frame through a fastening rod.

[0010] Preferably, the fixing component includes a bottom plate fixedly connected to the support frame, and the bottom plate is fixedly connected to the tank body through a locking rod.

[0011] Preferably, a plug frame is fixedly connected to the bottom of the cover body. The outer wall of the plug frame is inserted into the top of the tank body through a coupling groove, and a sealing gasket that abuts against the outer wall of the plug frame is filled in the inner wall of the coupling groove.

[0012] Preferably, the tank body is made transparent, the cover body is fixedly connected to the support frame through a connecting plate, and the connecting plate, the bottom plate and the support frame are integrally formed.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, the magnesium strip is put into the tank body from the magnesium strip feeding port, sealed, evacuated, and then a water sample is injected into the reaction vessel. The tank body is heated to make the magnesium strip react with the water sample to generate deuterium-labeled hydrogen. After the reaction vessel is cooled to room temperature, the deuterium-labeled hydrogen in the tank body is sucked out, injected into the gas isotope mass spectrometer and the deuterium isotope abundance in the water sample is calculated. While ensuring the normal detection of the deuterium isotope abundance, both the cover body and the tank body are fixed to the support frame, and the base at the bottom of the support frame is combined with the suction cup to ensure the stable connection between the storage tank and the workbench surface, avoiding the offset of the storage tank, thereby improving the stability of the storage tank for detecting the deuterium gas isotope abundance.

[0015] 2. In this application, the support plate abuts against the bottom of the tank body, which can further ensure the stable position of the tank body. Subsequently, the fastening rod is separated, and then the support plate is separated from the tank body from below, and then the locking rod is separated. At this time, the tank body can be conveniently separated from the cover body, so as to facilitate the subsequent cleaning and maintenance of the tank body, thereby ensuring the convenience of using the storage tank for detecting the deuterium gas isotope abundance.

The support plate 12 abuts against the bottom of the tank body 1, which can further ensure the stability of the position of the tank body 1. The fastening rod 14 is subsequently separated, and then the support plate 12 is separated from the tank body 1 from below, and then the locking rod 9 is separated. At this time, the tank body 1 can be easily separated from the cover body 2, which is convenient for the subsequent cleaning and maintenance of the tank body 1, thereby ensuring the convenience of using the storage tank for deuterium gas isotope abundance detection.
