Description

Technical Field

[0001] The present invention relates to the technical field of gas extraction, and particularly to a high-frequency induction heating furnace for extracting rare gases from trace samples. Background Art

[0002] The content and isotope composition of rare gases (helium, neon, argon, krypton, xenon) in rock and mineral samples play an important role in studying their genesis and evolution, fluid migration information related to mineral genesis, etc. Accurate analysis of the isotope composition and content of rare gases in samples is the basic premise for giving full play to their role. The prerequisite for accurately analyzing rare gases in samples is to efficiently extract the rare gases therein, purify the extracted rare gases, and then introduce the rare gases into a rare gas mass spectrometer for analysis of the content and isotope composition.

[0003] For some precious samples, such as lunar regolith, only a very small amount of samples can be provided for the analysis and application of rare gases. This requires maintaining an extremely low thermal background and a high gas extraction efficiency during the heating and extraction of rare gases in the samples. Currently, there are mainly two methods for extracting rare gases from samples: a double-vacuum resistance heating furnace and a carbon dioxide laser heater.

[0004] However, the structure of the double-vacuum resistance heating furnace is relatively complex, and the heating elements need to be replaced regularly to ensure normal use, with relatively high prices and operating costs. In addition, to ensure a low atmospheric permeability of the tantalum tube at high temperatures, the wall of the tantalum tube is generally designed to be relatively thick, which will cause a large amount of gas to be released inside the wall of the tantalum tube at high temperatures, resulting in a high thermal background, which has a great impact on the accurate analysis of rare gases in trace rock samples. The advantage of the carbon dioxide laser heating extraction method is an extremely low thermal background, but it cannot accurately measure the heating temperature of the sample and cannot be used to study the release curve of rare gases in rock samples with temperature. Moreover, the energy within the laser beam spot is distributed in a Gaussian manner and is not uniform, which also brings the problem of uneven heating of the sample and may cause incomplete melting of the sample. Summary of the Invention

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] To make the objectives, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] As Figure 1 shown, the present invention provides a high-frequency induction heating furnace for extracting rare gases from trace samples, including a sample introduction component, a vacuum furnace body component, a sample accommodation component, and a heating component.

[0041] The sample introduction component is arranged at the upper end of the vacuum furnace body component. The sample accommodation component is suspended inside the vacuum furnace body component through multiple tantalum wires 15, specifically on the inner wall of the vacuum furnace body component. The heating component is sleeved on the outer wall of the vacuum furnace body component, and the heating component and the sample accommodation component are at the same height. The heating component is used to heat and extract the sample inside the sample accommodation component. When the heating component starts to work, the sample accommodation component senses the heat of the heating component and heats up, thereby heating the sample accommodated inside the sample accommodation component, and then realizing the extraction of the gas in the sample.

[0042] The vacuum furnace body component at least includes a first quartz glass tube 14 and a second quartz glass tube 13. The second quartz glass tube 13 is sleeved on the outer wall of the first quartz glass tube 14, so as to form a circulation cavity between the first quartz glass tube 14 and the second quartz glass tube 13. The circulation cavity is used for circulating a coolant to provide a low-temperature environment for the sample introduction component and the sample accommodation component. Thus, when the sample accommodation component generates thermal radiation at a high temperature, based on the temperature and air pressure difference inside and outside the first quartz glass tube 14, the atmospheric permeability is reduced, and further the extraction accuracy of rare gases in trace samples is ensured. In addition, the coolant used is generally cooling water.

[0043] The sample introduction component includes a sample pushing component, a bellows 3, a threaded rod 4, and a quartz tube 12. The sample pushing component includes a strong magnet 1 and a magnetizable iron column 2.

[0044] The quartz tube 12 includes a horizontal tube and a vertical tube, and the horizontal tube and the vertical tube are T-shaped structures; the horizontal tube is connected to the upper end surface of the bellows 3, and the two are sealed by welding; the vertical tube passes through the upper end surface of the bellows 3, extends into the interior of the first quartz glass tube 14, and then extends into the interior of the sample accommodating component to ensure that the input sample falls accurately into the sample accommodating component. A threaded rod 4 with adjustable height is set on the side of the bellows, and the threaded rod 4 is used to drive the bellows 3 to expand and contract, and then drive the quartz tube 12 to move up and down.

[0045] The strong magnet column 1 is arranged on the outer wall of the horizontal tube, and the magnetizable iron column 2 is arranged on the inner wall of the horizontal tube, and the magnetizable iron column 1 and the strong magnet column 2 are arranged correspondingly; when working, the strong magnet column 1 moves, thereby driving the magnetizable iron column 2 to input the sample stored in the horizontal tube into the sample containing component through the vertical tube.

[0046] Furthermore, the vacuum furnace assembly further includes a stainless steel flange 6 and a metal-quartz transition kovar 8. The upper end of the stainless steel flange 6 is connected to the sample introduction assembly, and the lower end of the stainless steel flange 6 is connected to the upper end of the metal-quartz transition kovar 8 by welding; the lower end of the metal-quartz transition kovar 8 is connected to the first quartz glass tube 14 by welding. Specifically, the stainless steel flange 6 is a CF35 stainless steel flange. The lower end surface of the bellows 3 is a flange knife edge, and an oxygen-free copper gasket 5 is used to seal the bellows 3 and the CF35 stainless steel flange.

[0047] A gas pipeline is provided on the side wall of the metal-quartz transition kovar 8; a vacuum pump valve 9 and an extraction gas outlet valve 10 are provided on the gas pipeline.

[0048] The sample holding component is a tantalum crucible 16, which is formed by an integral stamping process and needs to be annealed at a high temperature of 1200°C before use. The tantalum crucible 16 is suspended on the inner wall of the metal-quartz transition layer by a plurality of tantalum wires 15. The number of the tantalum wires can be 3. Compared with other fixing methods of sample holding components in the prior art, the above-mentioned suspension setting method adopted by the present invention can make the tantalum crucible 16 release only a very small amount of gas during the gas extraction process of the rock sample, and the thermal background is extremely low, which reduces the influence on the component analysis of the rare gas extracted from the sample.

[0049] Preferably, the diameter of the tantalum wire 15 is 0.15 mm, and the wall thickness of the tantalum crucible 16 is 0.3 mm. A first cooling water inlet 18 is welded to the lower end of the second quartz glass tube 13, and a first cooling water outlet 11 is welded to the upper end of the second quartz glass tube 13. The second quartz glass tube 13 is connected to the outer wall of the first quartz glass tube 14 by a welding process.

[0050] The heating assembly includes a copper tube induction coil 17, a first insulating ceramic 21, and a second insulating ceramic 22; the copper tube induction coil 17 is sleeved on the outer wall of the vacuum furnace body assembly, and the copper tube induction coil 17 and the sample accommodating component are at the same height. Circulating cooling water flows through the copper tube induction coil 17. One end of the copper tube induction coil 17 is a second cooling water inlet 20, and the other end of the copper tube induction coil 17 is a second cooling water outlet 23; moreover, the first insulating ceramic is arranged at the second cooling water inlet 20, and the second insulating ceramic is arranged at the second cooling water outlet 23.

[0051] The high-frequency induction heating furnace further includes an infrared thermometer 19 and an intelligent temperature control meter 21; both ends of the copper tube induction coil 17 are also electrically connected to the intelligent temperature control meter 21. The infrared thermometer 19 is arranged at the lower end of the first quartz glass tube 14. The infrared thermometer 19 and the intelligent temperature control meter 21 are connected by a signal line. A coaxial laser aiming system is arranged in the infrared thermometer 19. By laser-aligning the bottom of the tantalum crucible, it is ensured that the diameter of the monitoring beam spot of the infrared thermometer 19 is smaller than the diameter of the bottom of the tantalum crucible 16, so as to accurately detect the temperature of the sample inside the tantalum crucible 16. The intelligent temperature control meter 21 is used to set the extraction temperature and extraction time.

[0052] Specifically, the intelligent temperature control meter 24 is connected to the straight pipe part of the copper tube induction coil 17 through a cable. The two ports of the straight pipe part of the copper tube induction coil 17 are respectively the second cooling water inlet 20 and the second cooling water outlet 23. The second cooling water inlet 20 and the second cooling water outlet 23 are insulated from the straight pipe part of the copper tube induction coil 17 through the first insulating ceramic 21 and the second insulating ceramic 22 respectively. The power switch 25 and the intelligent temperature control meter 24 are connected by a cable, and the power switch 25 is connected to a 220V AC power supply.

[0053] In a specific embodiment, when the high-frequency induction heating furnace provided by the present invention extracts rare gases from trace samples, the working process is as follows:

[0054] (1) Loading samples

[0055] The T-shaped quartz tube 12 and the corrugated pipe 3 are removed from the CF35 stainless steel flange 6 as a whole. The accurately weighed rock sample is packed into the horizontal pipe of the T-shaped quartz tube 12 with aluminum foil, and then the corrugated pipe 3 is sealed with the CF35 stainless steel flange 6 through the oxygen-free copper gasket 5. The vacuum pump valve 9 is opened to prepare a ultra-high vacuum for the quartz tube.

[0056] (2) Degassing of tantalum crucible

[0057] After the vacuum degree reaches the requirement, the cooling circulating water valve is opened to allow the cooling circulating water to enter the circulation cavity through the first cooling water inlet 18, and then flow out from the first cooling water outlet 11 to form a circulating cooling, so as to cool the vacuum furnace body (the first quartz tube and the second quartz tube); at the same time, it flows into the copper tube induction coil 17 through the second cooling water inlet 20 and flows out of the copper tube induction coil 17 through the second cooling water outlet 23 to form a circulating cooling to cool the copper tube induction coil 17. It should be noted that when the copper tube induction coil 17 is heated, its own temperature is also very high, so it is necessary to pass cold water inside the copper tube induction coil 17 to cool it.

[0058] The infrared thermometer 19 is turned on, and the laser aiming system inside the infrared thermometer is used to aim at the bottom of the tantalum crucible 16. The intelligent temperature control meter is set to 400 °C, and then the high-frequency power supply switch 25 is turned on. The tantalum crucible 16 starts to be heated for degassing, and the gas is pumped away through the vacuum pump valve 9. The heating degassing time is 10 min. Then, according to the above steps, set by the intelligent temperature control meter 24, the tantalum crucible 16 is heated at a temperature step of 100 °C for 10 min each, and the tantalum crucible is heated to 1600 °C in this way for high-temperature degassing.

[0059] (3) Sample extraction

[0060] After the thermal background of the tantalum crucible 16 reaches the requirement, the tantalum crucible 16 is cooled to room temperature through the intelligent temperature control meter 24. The vacuum pump valve 9 is closed, and by adjusting the threaded rod 4, the vertical pipe of the T-shaped quartz tube 12 is extended into the tantalum crucible. The strong magnet column 1 is pushed to drive the magnetizable iron column 2 to push the sample, and the sample falls into the tantalum crucible 16 through the vertical pipe part of the T-shaped quartz 12.

[0061] The intelligent temperature control meter is set to 400 °C, the high-frequency power supply switch 25 is turned on, and the tantalum crucible 16 starts to heat to extract the gas in the sample. The extraction time is 10 min. The extraction gas outlet valve 10 enters the analysis system for analysis. Then, according to the above steps, set by the intelligent temperature control meter 24, the tantalum crucible 17 is heated at a temperature step of 100 °C for 10 min each, and the tantalum crucible 17 is heated to 1600 °C in this way to extract and analyze the gas in the sample at different temperature steps.

[0062] If it is necessary to completely melt the sample at one time and extract the gas, the tantalum crucible temperature is directly set to 1600 °C and the extraction time is 10 min through the intelligent temperature control meter 24, and the gas therein is extracted and enters the analysis system through the outlet valve 10 for analysis. After the analysis is completed, the tantalum crucible temperature is set to 1700 °C and the extraction time is 10 min through the intelligent temperature control meter 24 to further extract the gas and enter the analysis system through the valve 10 for analysis to monitor whether the sample is completely melted.

[0063] Compared with the prior art, the present invention also has the following advantages:

[0064] The present invention provides a high-frequency induction heating furnace for extracting rare gases from trace samples. The wall thickness of the tantalum crucible for melting the sample is only 0.3 mm and the mass is only 0.8 g. Even at high temperatures, the tantalum crucible itself only releases extremely trace amounts of gas, and the thermal background is extremely low; the combined use of a high-precision infrared thermometer and an intelligent temperature control instrument can accurately measure and adjust the heating temperature of the sample; the entire heating furnace structure is very simple, easy to maintain, and has a low use cost.

[0065] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same and similar parts among the embodiments, reference can be made to each other.

[0066] Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
