[0003] The deoxygenation device for ultra-dry reagents generally consists of a reaction vessel, a deoxygenation unit, an air intake and exhaust system, and auxiliary components. The ultra-dry reagent deoxygenation device creates an oxygen-free environment by venting air through the air intake system, removes oxygen using a deoxygenating agent, assists in deoxygenation with a gas circulation component (if present), and ensures that the oxygen content meets the standard by real-time monitoring and control devices. Finally, the deoxygenated reagent is output and subsequent device maintenance is performed in preparation for the next operation.
[0004] Existing deoxygenation devices for ultra-dry reagents cannot achieve rapid sealing and connection of pipelines without tools. If existing deoxygenation devices for ultra-dry reagents cannot achieve rapid sealing and connection of pipelines without tools, they will result in long operating times, cumbersome procedures, difficulty in rapid response and limited flexibility in emergency handling, increased difficulty in maintenance and inconvenience for frequent maintenance, and increased costs such as tool costs and wear and tear, and increased labor costs, which will affect the overall use effect and efficiency of the device. Therefore, a deoxygenation device for ultra-dry reagents is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 3This utility model provides an embodiment of a deoxygenation device for ultra-dry reagents, comprising a base plate 1 made of robust and corrosion-resistant stainless steel. This material ensures the stable structure of the entire device during long-term use and is not easily damaged by external environmental factors such as humidity or chemical reagent corrosion, providing a reliable support foundation for other components of the device. A deoxygenation tank 4 is fixedly connected to the top of the base plate 1. The deoxygenation tank 4 is made of high-strength glass, which has good chemical stability and can withstand the effects of ultra-dry reagents and various chemical reactions during the deoxygenation process. Simultaneously, it facilitates observation of the internal reagent condition, ensuring that the deoxygenation operation can be carried out smoothly and intuitively.
[0033] The top of the deaerator 4 is fixedly connected to a fixing column 5. The fixing column 5 is made of hard alloy steel, possessing excellent wear resistance and mechanical strength. It maintains its structural integrity during frequent connection and rotation operations, ensuring the normal operation of subsequent mating components. A sliding column 10 is slidably connected to the outside of the fixing column 5. The sliding column 10 is also made of corrosion-resistant alloy material. This material prevents wear and deformation during repeated relative sliding and rotation operations with the fixing column 5, ensuring the sealing and reliability of the connection. The sliding column 10 has a groove inside. The groove is designed with high precision, allowing it to accurately mate with the fixing block 9. This makes the fixing block 9 more stable when sliding and fixing within the groove, effectively preventing loosening or misalignment, thus ensuring the strength of the connection.
[0034] A sealing ring 8 is slidably connected inside the sliding column 10. The sealing ring 8 is made of rubber with good elasticity and sealing performance. When subjected to external pressure, it can undergo moderate deformation and fit tightly against the inner wall of the sealing shell 6, thereby achieving a good sealing effect, preventing gas or reagent leakage, and ensuring the deoxygenation environment inside the entire device and the sealing performance of the reagent transfer process. The sealing shell 6 is slidably connected to the outer side of the sealing ring 8. The sealing shell 6 is made of high-temperature resistant and corrosion-resistant engineering plastic material. It can provide a stable housing space for the sealing ring 8 and, when combined with other components, play a role in auxiliary sealing and protecting the internal structure, making the entire sealing structure more stable and reliable.
[0035] The internal fixed connection of the sealing shell 6 has multiple springs 7, which are presumably similar to elastic support components, such as small springs 16. These components are made of high-quality elastic metal materials and have good elastic recovery ability. They can quickly rebound after being compressed. The force generated by the rebound makes the fixing block 9 more tightly connected to the inside of the sliding column 10, further enhancing the stability of the connection and ensuring that the device will not accidentally disengage during operation.
[0036] The other end of spring 7 is fixedly connected to the inside of sealing ring 8. This connection method allows the entire sealing-related structure to work synergistically, better fulfilling the sealing function. A fixing block 9 is slidably connected to the outside of the fixing post 5. The fixing block 9 is made of wear-resistant and high-strength metal, which can maintain its shape and structural integrity during repeated friction and engagement with the slot, ensuring accurate connection every time and providing strong support for reliable connection and sealing of the device. The outside of the fixing block 9 is slidably connected to the inside of the slot; the two fit tightly together, achieving a stable and flexibly detachable connection between the sliding post 10 and the fixing post 5, facilitating operation according to actual needs.
[0037] A control device 2 is fixedly connected to the top of the base plate 1. The outer shell of the control device 2 is made of plastic with good insulation properties. It integrates an advanced electronic control module, which can accurately control the deoxygenation operation of the deoxygenation tank 4 and the start and stop of the water pump 3. The operation is simple and convenient, which improves the automation level and work efficiency of the entire device, and makes it easier for staff to deoxygenate ultra-dry reagents.
[0038] A water pump 3 is fixedly connected to the top of the base plate 1. The water pump 3 is a high-precision micro water pump, which features stable flow and moderate suction. It can smoothly and efficiently transfer the ultra-dry reagent in the deoxygenation tank 4 to the subsequent collection box 11, ensuring that the reagent transfer process is uninterrupted or the flow is unstable, and guaranteeing the smooth operation of the entire process. A filter assembly for filtering particles is fixedly connected to one side of the water pump 3.
[0039] Reference Figure 1 , Figure 2 , Figure 4 The filtration assembly includes a collection box 11, which is made of transparent plexiglass. This material not only facilitates observation of the internal filtration process but also exhibits good chemical stability, allowing it to remain in contact with ultra-dry reagents for extended periods without undergoing a chemical reaction. The bottom of the collection box 11 is fixedly connected to the top of the base plate 1. This robust connection ensures its stable position during device operation, preventing shaking or displacement and guaranteeing the proper functioning of the filtration process.
[0040] The outer side of the collection box 11 is fixedly connected to one end of the water pump 3, and the two are tightly connected, allowing the ultra-dry reagent from the water pump 3 to smoothly enter the collection box 11 for filtration. Inside the collection box 11, two limiting frames 12 are fixedly connected. These limiting frames 12 are made of rigid plastic and have high internal dimensional accuracy, precisely limiting the sliding range of the filter plate 13 and its cooperating sliding block 14, ensuring that the filter plate 13 performs its filtration function in the appropriate position without displacement or detachment. The filter plate 13 is slidably connected inside the limiting frames 12. The filter plate 13 is made of a filter mesh material with fine pores, the pore size of which is carefully designed to effectively intercept particulate impurities generated during the deoxygenation process of the ultra-dry reagent, making the filtered ultra-dry reagent more pure and meeting the purity requirements for subsequent use.
[0041] A sliding block 14 is slidably connected to the top of the filter plate 13. The sliding block 14 is made of smooth plastic, which results in low friction when sliding inside the limiting frame 12, facilitating operation. It also provides stable support and positioning for the filter plate 13, ensuring its position remains fixed during filtration and enabling stable filtration. The two sides of the sliding block 14 are slidably connected inside the limiting frame 12, with a tight fit between them. This ensures smooth sliding of the sliding block 14 within the limiting frame 12 without any abnormalities such as dislodgement, guaranteeing the normal operation of the entire filter assembly.
[0042] A hollow rod 15 is fixedly connected inside the sliding block 14. The hollow rod 15 is made of lightweight and sufficiently strong metal tubing, providing a stable space for the internal sliding rod 17, while also playing a connecting and supporting role in the overall structure of the device. The sliding rod 17 is slidably connected inside the hollow rod 15. The sliding rod 17 is made of smooth-surfaced metal material, which slides flexibly inside the hollow rod 15, facilitating related operations and enabling the fixing and disassembly of the filter plate 13.
[0043] The outer side of the sliding rod 17 is slidably connected to the inside of the hollow rod 15. The cooperation between the two ensures smooth sliding and, through certain structural constraints, ensures the stability of the positional relationship of the relevant components. The outer side of the sliding rod 17 is slidably connected to the inside of the sliding block 14. This multi-layered nesting and sliding connection makes the fixing and disassembly mechanism of the entire filter plate 13 more reliable and flexible.
[0044] A second spring 16 is fixedly connected to the inner side of the sliding rod 17. The second spring 16 is a metal spring with a suitable elastic coefficient, which can generate sufficient elastic force when the sliding rod 17 is pulled. When the external force disappears, the sliding rod 17 can automatically spring back to its original position, thereby realizing the automatic fixing function of the filter plate 13. This facilitates operation and ensures the stability of the filter plate 13 during normal use. The end of the sliding rod 17 away from the second spring 16 is slidably connected to the inside of the limiting frame 12. This connection further improves the structural correlation of the entire filter assembly, enabling the various components to work together and ensuring that the filter plate 13 can perform filtering normally and subsequent replacement and cleaning operations.
[0045] Working principle: When the operator needs to deoxygenate the ultra-dry reagent, the pipe can be connected to the sliding column 10. After the sliding column 10 is connected to the pipe, it can be slid to the outside of the fixed column 5. When the outside of the fixed column 5 slides to the inside of the sliding column 10, the fixed block 9 connected to the outside of the fixed column 5 can be slid into the groove opened inside the sliding column 10 by rotating the sliding column 10. When the sliding column 10 slides downward, it will compress the sealing ring 8 downward, thereby causing the sealing ring 8 to slide into the sealing shell 6. The sealing shell 6 contains multiple springs 7. When the sealing ring 8 is compressed, the multiple springs 7 are also compressed. When the sliding post 10 is connected to the fixed post 5, the sliding post 10 is released. At this time, the compressed springs 7 will rebound due to the loss of pressure. The rebound force will make the fixed block 9 more tightly connected to the inside of the sliding post 10. When the sliding post 10 needs to be removed, it can be removed by rotating the sliding post 10, so that the fixed block 9 disengages from the slot inside the sliding post 10.
[0046] Once the pipeline is connected to the deoxygenation tank 4 via the sliding column 10, the ultra-dry reagent can be transferred to the inside of the deoxygenation tank 4 through the pipeline. At this time, the deoxygenation tank 4 is started to deoxygenate the ultra-dry reagent inside the deoxygenation tank 4. After deoxygenation is completed, the water pump 3 is started to transfer the ultra-dry reagent inside the deoxygenation tank 4 to the inside of the collection box 11. The collection box 11 is equipped with two limiting frames 12, and a filter plate 13 slides inside the limiting frame 12. The filter plate 13 can then filter the particles generated by the ultra-dry reagent during the deoxygenation process. The particles passing through the filter plate 13 will be transferred out from the other end of the collection box 11, making the ultra-dry reagent more pure. When the filter plate 13 needs to be replaced, the sliding rod 17 can be pulled by the handle on the outside of the sliding rod 17, causing the sliding rod 17 to slide into the sliding block 14, so that the sliding rod 17 slides out from one end of the limiting frame 12. In this way, the sliding block 14 can be removed from the inside of the limiting frame 12, and the filter plate 13 can be removed for replacement or cleaning.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
