Description

Technical Field

[0001] This invention relates to the field of deoxygenation equipment technology, and in particular to a liquid metal deoxygenation device for slowing down the corrosion of lead-bismuth alloys. Background Technology

[0002] Lead-bismuth alloy is a low-melting-point alloy composed of lead and bismuth, possessing unique physicochemical properties and demonstrating significant application value in multiple fields. The following problems exist: The key to slowing down the corrosion of lead-bismuth alloys lies in strictly controlling their oxygen content. This is usually achieved by using chemical deoxygenation devices, which can effectively remove oxygen dissolved in the alloy, thereby reducing the corrosion rate. However, during the deoxygenation process, a large number of solid impurities are inevitably generated. If these impurities remain in the alloy, they will also exacerbate the material deterioration. Since most common deoxygenation devices currently lack the function of efficiently filtering solid impurities, the impurities cannot be fully removed after deoxygenation, thus affecting the quality of liquid lead-bismuth alloys. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A liquid metal deoxygenation device for mitigating corrosion of lead-bismuth alloys includes a reaction vessel. Multiple sets of columns are fixedly connected to the bottom outer edge of the reaction vessel. A top shell is fixedly connected to the bottom of each column. A semi-circular back plate is fixedly connected to the bottom of the outer wall of the top shell. A bottom shell is fixedly connected to the bottom of the arc-shaped concave surface of the semi-circular back plate. A filter mechanism is installed between the top shell and the bottom shell. A recovery tank is fixedly connected to the bottom of the bottom shell. A base is fixedly connected to the bottom of the recovery tank. An oxygen content sensor passes through one end of the bottom of the recovery tank, and a discharge pipe passes through the other end of the bottom of the recovery tank.

[0006] As a further description of the above technical solution: The filtration mechanism includes a sieving ring. The sieving ring is slidably connected to the opposite surfaces of the top shell and the bottom shell. A support ring is fixedly connected to the bottom of the inner wall of the sieving ring. Multiple sets of spring cylinders are fixedly connected to the top of the support ring. A through-hole is opened at the center of the top of each spring cylinder. A spring rod is slidably connected to the inner wall of each hole. Buffer springs are sleeved at both ends of the outer wall of each spring rod.

[0007] As a further description of the above technical solution: The inner wall of the sieving ring is slidably connected to the top of the sliding ring, and the bottom of the sliding ring is fixedly connected to the top of the spring rod. The inner wall of the sliding ring is fixedly connected to the inner ring, the top of the inner wall of the inner ring is fixedly connected to the filter screen, the bottom of the inner wall of the inner ring is fixedly connected to the guide ring, the top of the outer wall of the inner ring is fixedly connected to the vibration ring, and the top two ends of the vibration ring are fixedly connected to the vibration motor.

[0008] As a further description of the above technical solution: A first valve is fixedly connected to the bottom of the discharge pipe, and a second valve passes through the center of the bottom of the recycling tank. A conveying pipe is sleeved at the outlet of the rear end of the second valve.

[0009] As a further description of the above technical solution: The inner wall of the reaction vessel is fitted with a top cover, and a feed pipe extends through one end of the top of the top cover. A sealing cap is fitted onto the inner wall of the feed pipe.

[0010] As a further description of the above technical solution: A one-way valve is inserted through the other end of the top of the top cover. An exhaust pipe is fixedly connected to the top opening of the one-way valve. A pump body is inserted through the center of the top of the top cover. The inlet of the rear end of the pump body is sleeved with the top of the outer wall of the delivery pipe.

[0011] As a further description of the above technical solution: A third valve is inserted through the center of the bottom of the reaction vessel, and a conduit is fixedly connected to the bottom outlet of the third valve. The bottom end of the outer wall of the conduit penetrates vertically downward through the center of the top of the top shell.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) By setting up a filter screen, a large number of solid impurities generated by the reaction can be screened and filtered. By setting up a spring cylinder, spring rod and buffer spring, an elastic element can be formed, which can make the slip ring have the characteristic of shaking up and down. When the vibration motor is turned on, the vibration ring will shake with the filter screen in the inner ring, which not only improves the screening efficiency of a large number of solid impurities, but also avoids the clogging of the filter screen.

[0013] (2) By setting a simple connection between the sieve ring, top shell and bottom shell, the disassembly and assembly of the filter mechanism is more convenient and quick. It also makes it easier for staff to uniformly process the solid impurities accumulated on the top surface of the filter screen. The detection probe of the oxygen content sensor extends into the interior of the liquid lead-bismuth alloy and can detect the oxygen content of the liquid lead-bismuth alloy. The detection result is displayed on the display screen at the bottom of the oxygen content sensor. The display content includes oxygen-rich, oxygen-controlled or oxygen-poor. If oxygen-poor is displayed, the first valve can be opened to allow the liquid lead-bismuth alloy to be discharged automatically. If oxygen-rich or oxygen-controlled is displayed, the second valve can be opened to allow the liquid lead-bismuth alloy to flow into the conveying pipe. By setting the pump body and the conveying pipe, the liquid lead-bismuth alloy in the recovery tank can be transported back to the reaction tank for further processing. Attached Figure Description

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0019] Reference Figure 1-3 One embodiment of the present invention provides a liquid metal deoxygenation device for slowing down the corrosion of lead-bismuth alloy, comprising a reaction vessel 1, in which the lead-bismuth alloy reacts, generating gaseous and solid impurities. Multiple sets of columns 2 are fixedly connected to the bottom outer edge of the reaction vessel 1. A top shell 3 is fixedly connected to the bottom of each column 2. The bottom of the top shell 3 has an opening. A semi-circular back plate 4 is fixedly connected to the bottom of the outer wall of the top shell 3. A bottom shell 5 is fixedly connected to the bottom of the arc-shaped concave surface of the semi-circular back plate 4. The top of the bottom shell 5 has an opening. A slidable sieve ring 61 is connected to the opposite surfaces of the top shell 3 and the bottom shell 5. A support ring is fixedly connected to the bottom of the inner wall of the sieve ring 61. 62. The bottom surface of the support ring 62 and the bottom surface of the screening ring 61 are both set on the same horizontal plane. Multiple sets of spring cylinders 63 are fixedly connected to the top of the support ring 62. A through-hole is opened at the center of the top of each spring cylinder 63, and a spring rod 64 is slidably connected to the inner wall of each hole. Buffer springs 65 are sleeved on both ends of the outer wall of each spring rod 64. A slip ring 66 is slidably connected to the top of the inner wall of the screening ring 61. The bottom of each slip ring 66 is fixedly connected to the top of the spring rod 64. By setting the spring cylinders 63, spring rods 64 and buffer springs 65, an elastic element can be formed, which allows the slip ring 66 to have the characteristic of swaying up and down.

[0020] An inner ring 67 is fixedly connected to the inner wall of the slip ring 66. A filter screen 68 is fixedly connected to the top of the inner wall of the inner ring 67. By setting the filter screen 68, a large amount of solid impurities generated in the reaction can be screened and filtered. A guide ring 69 is fixedly connected to the bottom of the inner wall of the inner ring 67. By setting the guide ring 69, the liquid lead-bismuth alloy after screening and filtration can be guided. A vibrating ring 610 is fixedly connected to the top of the outer wall of the inner ring 67. A vibration motor 611 is fixedly connected to both ends of the top of the vibrating ring 610. When the vibration motor 611... After being turned on, the vibrating ring 610 will shake along with the filter screen 68 in the inner ring 67, which not only improves the screening efficiency of a large number of solid impurities, but also avoids the clogging of the filter screen 68. The top and bottom surfaces of the screening ring 61 are in close contact with the opposite surfaces of the top shell 3 and the bottom shell 5. By setting the screening ring 61, the support ring 62, the spring cylinder 63, the spring rod 64, the buffer spring 65, the slip ring 66, the inner ring 67, the filter screen 68, the guide ring 69, the vibrating ring 610 and the vibrating motor 611, the filtration mechanism 6 can be formed.

[0021] The semi-circular back plate 4 serves to limit the installation of the filter mechanism 6. The simplified connection between the sieve ring 61, top shell 3, and bottom shell 5 makes the assembly and disassembly of the filter mechanism 6 easier and faster. It also facilitates the unified treatment of solid impurities accumulated on the top surface of the filter screen 68. A recovery tank 7 is fixedly connected to the bottom of the bottom shell 5. The recovery tank 7 collects the liquid lead-bismuth alloy after deoxygenation filtration. A base 8 is fixedly connected to the bottom of the outer wall of the recovery tank 7. An oxygen content sensor 9 penetrates one end of the bottom of the recovery tank 7. Notably, the detection probe of the oxygen content sensor 9 extends into the liquid lead-bismuth. Inside the alloy, the oxygen content of the liquid lead-bismuth alloy can be detected.

A discharge pipe 10 runs through the other end of the bottom of the recovery tank 7. A first valve 11 is fixedly connected to the bottom of the discharge pipe 10. A second valve 12 runs through the center of the bottom of the recovery tank 7. A conveying pipe 13 is connected to the outlet of the rear end of the second valve 12. If the display shows oxygen deficiency, the first valve 11 can be opened to allow the liquid lead-bismuth alloy to be discharged automatically. If the display shows oxygen-rich or oxygen-controlled, the second valve 12 can be opened to allow the liquid lead-bismuth alloy to flow into the conveying pipe 13.

[0022] A top cover 14 is fitted onto the top of the inner wall of reaction vessel 1. A feed pipe 15 passes through one end of the top of the top cover 14, and a sealing cap 16 is fitted onto the inner wall of the feed pipe 15. A one-way valve 17 passes through the other end of the top of the top of the top cover 14. An exhaust pipe 18 is fixedly connected to the top opening of the one-way valve 17. By setting the exhaust pipe 18, the gases produced by the chemical reaction can be quickly discharged. By setting the one-way valve 17, external gases can be prevented from entering reaction vessel 1. A pump body 19 passes through the center of the top of the top of the top cover 14. The inlet at the rear end is sleeved with the top of the outer wall of the conveying pipe 13. By setting up the pump body 19 and the conveying pipe 13, the liquid lead-bismuth alloy in the recovery tank 7 can be transported back to the reaction tank 1 for further processing. A third valve 20 is passed through the center of the bottom of the reaction tank 1. A conduit 21 is fixedly connected to the bottom outlet of the third valve 20. The bottom end of the outer wall of the conduit 21 passes vertically downward through the center of the top of the top shell 3. After the reaction is completed, the third valve 20 is opened, allowing the liquid lead-bismuth alloy in the reaction tank 1 to flow into the top shell 3.
