Abstract
Description
Technical Field
[0001] This application relates to the field of environmental simulation and pressure testing equipment technology, and in particular to an oxygenation cycle test device. Background Technology
[0002] In the safety and lifespan assessment of modern special equipment, the oxygen-filling cycle test is a crucial step. The gas cylinder to be tested is placed in a sealed test chamber, and gas at specific pressures and concentrations, along with auxiliary test media, are periodically injected into the chamber through an external gas supply unit. Utilizing the heating and fluid circulation mechanisms inside the chamber, the gas continuously convects within the chamber and acts on the surface of the gas cylinder under test, thereby simulating harsh oxidation, fatigue, and aging working environments.
[0003] Existing oxygen-filling cycle testing equipment typically employs a straight-through airflow exchange structure. It extracts gas using a booster pump or air compressor and injects the pressurized gas directly from one side or bottom of the equipment housing via a single straight pipe or a guide pipe with simple flow equalization orifices. Simultaneously, a conventional fan impeller is usually installed in one corner inside the housing. Utilizing the initial kinetic energy of the incoming air and the forced mechanical agitation of the fan, the high-pressure, unconditioned gas just introduced into the chamber is directly blown towards the gas cylinder to be tested. Excess gas is then discharged back to the atmosphere or the circulation system through a pressure relief valve at the top or side.
[0004] However, existing oxygen-filling cycle testing equipment suffers from blind spots and errors due to the direct impact of airflow on the gas cylinder under test. The air intake in existing equipment is a concentrated and high-speed jet, with the gas directly impacting a localized surface of the cylinder. This leads to excessive oxidation and physical stress on the windward side of the cylinder, while a fluid dead zone appears on the leeward side, making it impossible to form a uniform laminar flow coating and severely reducing the accuracy of the test results. How to solve these technical problems is a question that those skilled in the art need to consider. Summary of the Invention
[0005] To address the aforementioned technical problems, this application provides an oxygenation cycle test device.
[0006] This application provides an oxygen-filling cycle testing device including a processing chamber, a circulation mechanism, a support mechanism, and an adjustment mechanism. The processing chamber has a receiving space, an air inlet, and an air outlet. The air inlet communicates with the bottom of the receiving space, and the air outlet communicates with the receiving space. The circulation mechanism is connected to both the air inlet and the air outlet, and is used to fill the receiving space with the gas for testing and collect the tested gas. The support mechanism is located within the receiving space and connected to the processing chamber, and is used to support the gas cylinder to be tested. The adjustment mechanism is located within the receiving space and includes an adjustment component and a speed reducer. The adjustment component is located below the support mechanism and includes a buffer component and a diffuser. The buffer component is connected to the processing chamber, with its buffer wall facing the air inlet. The diffuser is connected to the side of the buffer component away from the buffer wall. The buffer component and the diffuser cooperate to disperse the agglomerated gas entering the processing chamber from the air inlet along the buffer component and the diffuser. The speed reducer is spaced above the adjustment component and connected to the processing chamber, and is used to reduce the velocity of the gas dispersed by the adjustment component.
[0007] Understandably, the oxygen-filling cycle test equipment incorporates an adjustment mechanism within the processing chamber. The adjustment component within this mechanism is located below the support structure, ensuring that the agglomerated gas entering the processing chamber from the inlet first contacts the adjustment component. The buffer wall of the buffer component faces the inlet, providing initial physical shielding and buffering of the concentrated, high-speed agglomerated gas, dispersing its initial kinetic energy. The diffuser is connected to the side of the buffer component away from the buffer wall; the combination of the buffer and diffuser disperses the buffered gas in various directions, altering its original jet state. Decelerators are spaced above the adjustment component to reduce the rising velocity of the dispersed gas, resulting in smoother gas flow. The combination of the adjustment and deceleration components prevents high-speed agglomerated gas from directly impacting the gas cylinder under test, preventing excessive oxidation on the windward side and fluid dead zones on the leeward side. This promotes a uniform laminar flow envelope within the chamber, improving the accuracy of the oxygen-filling cycle test results. This solves the technical problem in existing technologies where direct airflow impact on the gas cylinder under test easily causes test blind spots and errors.
[0008] In one embodiment, the first direction is vertical, the second direction is the direction in which gas enters the processing chamber, the buffer member is arranged along the first direction, and the buffer wall is arranged perpendicular to the second direction; the diffuser is connected to the buffer member and extends away from the buffer wall along the second direction, and the diffuser has a guide groove that extends along the second direction and communicates with the receiving space, the guide groove is used to guide the gas to disperse along the diffuser; the deceleration member and the processing chamber are in a deceleration chamber, the deceleration member has a plurality of vent holes that are arranged through the second direction, the plurality of vent holes are communicated with the deceleration chamber, and the deceleration member is used to slow down the speed of the gas flowing through the deceleration chamber.
[0009] Understandably, the buffer element, positioned along the first direction and with its buffer wall perpendicular to the second direction of gas entry, can effectively receive and block high-speed gas entering from the front over a large area. The diffuser extends along a straight line parallel to the second direction and features guide grooves that guide the gas after it has changed direction, forcing it to disperse outwards along the contour of the diffuser. The deceleration chamber provides space for the gas to reside, and multiple vents on the deceleration element further refine and divide the converging gas. As the airflow passes through the vents, it undergoes throttling expansion and mutual friction, slowing down the upward velocity of the gas flowing through the deceleration chamber and improving the uniformity of gas distribution.
[0010] In one embodiment, the adjustment assembly further includes a support member located on the side of the diffuser away from the buffer member along the second direction. The support member is connected to the diffuser and the processing box respectively. The support member is at least partially perpendicular to the second direction and is used to disperse the gas passing through the diffuser.
[0011] Understandably, the support component is located at the end of the diffuser furthest from the buffer component, serving to connect the diffuser to the processing box and improve the overall structural stability of the adjustment assembly. Simultaneously, the support component is at least partially perpendicular to the second direction of gas entry, enabling it to secondary obstruct residual airflow flowing out along the edge of the diffuser. The support component forces the gas to change its flow trajectory again at the end, dispersing the gas passing through the diffuser, avoiding excessive concentration of local airflow, and ensuring a uniform flow field.
[0012] In one embodiment, the third direction is perpendicular to the first and second directions. The adjustment mechanism includes two speed reducers and multiple adjustment components. The multiple adjustment components are arranged at equal intervals along the third direction. The two speed reducers are arranged at intervals along a straight line parallel to the second direction.
[0013] Understandably, multiple regulating components arranged at equal intervals along a third direction form an array-like gas buffer and dispersion area at the bottom of the processing chamber, ensuring that the wide airflow entering from the inlet receives equal treatment in all sections. Two speed reducers are arranged at intervals along a straight line parallel to the second direction, causing the gas to undergo multiple stages of obstruction during its ascent. This multi-layered, staggered spatial layout enhances the ability to block and regulate airflow, resulting in smoother and more efficient gas flow throughout the entire containment space.
[0014] In one embodiment, the processing box further includes heat dissipation holes, a heat dissipation structure, and a receiving cavity. The receiving cavity is connected to the receiving space and is used to accommodate the circulation mechanism. The receiving cavity is connected to the heat dissipation holes, and the heat dissipation structure is connected to the processing box at the position corresponding to the heat dissipation holes.
[0015] Understandably, the processing chamber has a recessed cavity to house the circulation mechanism, isolating it from the external environment, protecting it from external impurities, and making the overall structure more compact. The cavity is connected to the storage space, shortening the gas transmission path and reducing pressure loss during transmission. The heat dissipation holes and structure work together to promptly remove heat generated during circulation, preventing excessive internal temperatures that could affect the lifespan of the circulation mechanism and the temperature stability of the testing environment.
[0016] In one embodiment, the adjusting mechanism further includes a first isolation plate and a second isolation plate, which are spaced apart and connected to the processing box to divide the receiving cavity into a first cavity, a second cavity, and a third cavity that are interconnected. The circulation mechanism includes an oxygen generating component and a circulation component. The oxygen generating component is disposed inside the first cavity and connected to the first isolation plate, and the circulation component is disposed inside the third cavity and connected to the processing box. The oxygen generating component and the circulation component are connected.
[0017] Understandably, the first and second partition plates divide the receiving cavity into three interconnected chambers: a first chamber, a second chamber, and a third chamber. This regulates and guides the airflow channels within the receiving cavity. The cooperation of the first and second partition plates ensures that the gas within the receiving cavity flows orderly along a preset path. The oxygen generation component and the circulation component are respectively located inside the independent first and third chambers, preventing the gas flowing through them from directly impacting the processing chamber. This also avoids mutual interference between the components during operation, improves space utilization, and enhances the efficiency of gas generation and circulation.
[0018] In one embodiment, the oxygen generating assembly includes a base plate, fasteners, a raised frame, an air circulation pipe, a transport pipe, and a hydraulic tank. The base plate is connected to a first isolation plate, the fasteners are connected to the base plate and the raised frame respectively, the raised frame is connected to the air circulation pipe, and the air circulation pipe is connected to the transport pipe and the hydraulic tank respectively.
[0019] Understandably, the raised platform connects to the base plate via clips, facilitating the installation, disassembly, and maintenance of the oxygen generating components. Simultaneously, the raised platform supports the air circulation pipe at a certain height, providing ample bottom space for gas flow. The air circulation pipe connects to the transport pipe and hydraulic tank, forming a closed and smooth oxygen production and delivery loop. The hydraulic tank stabilizes the gas pressure, and the air circulation pipe guides the prepared gas into the transport pipe, ensuring the continuity of the oxygen production process and the stability of the gas output pressure.
[0020] In one embodiment, the circulation component includes a wind pusher frame, a support buffer column, a bidirectional wind pusher pipe, a gas release pipe, a transfer storage pipe, and a gas delivery pipe. The wind pusher frame is connected to a second isolation plate. The support buffer column is connected to the wind pusher frame and the bidirectional wind pusher pipe respectively. The gas release pipe is connected to the bidirectional wind pusher pipe. The transfer storage pipe and the gas release pipe are connected.
[0021] Understandably, the air pusher frame provides a stable mounting base for the entire circulation assembly, and the support buffer column plays a role in shock absorption and buffering when connecting the bidirectional air pusher pipe, reducing structural vibration caused by fluid impact. The bidirectional air pusher pipe, gas release pipe, transfer storage pipe, and gas delivery pipe are connected in sequence to form a complete gas circulation system. The transfer storage pipe plays a role in energy storage and buffering, while the bidirectional air pusher pipe enhances the gas delivery power, ensuring the smoothness and sufficiency of gas circulation into the containment space.
[0022] In one embodiment, the support mechanism includes a support member and a connector. The connector is disposed inside the receiving space and connected to the deceleration member. The connector is spaced apart from the adjustment component. The support member is disposed inside the receiving space and slidably connected to the connector. The support member is used to support the gas cylinder to be tested.
[0023] Understandably, the connecting parts are positioned at intervals with the speed reduction components and the adjustment assembly, utilizing the structural space at the bottom of the processing box to ensure the stability of the support mechanism without interfering with the buffering and diffusion of the gas. The sliding connection between the support and the connecting parts allows the user to flexibly adjust the position of the support within the accommodating space according to the size of the gas cylinder to be tested or the testing requirements. The movable support mechanism not only facilitates the loading and unloading of gas cylinders but also enhances the equipment's adaptability to test samples of different specifications.
[0024] In one embodiment, the oxygenation cycle test equipment further includes a first protective component and a second protective component, wherein the first protective component is connected to the position corresponding to the processing box and the receiving space, and the second protective component is connected to the position corresponding to the processing box and the receiving cavity.
[0025] Understandably, the first protective component covers the area corresponding to the processing chamber and the receiving space, while the second protective component covers the area corresponding to the processing chamber and the receiving cavity. The first and second protective components physically isolate the receiving space and the receiving cavity from the external environment. This prevents external dust and impurities from entering the oxygen-charging cycle test equipment and contaminating the test gas, while also avoiding safety hazards to operators caused by internal high-pressure gas leaks, thus enhancing the overall safety and sealing of the equipment.

[0034] The following is in conjunction with the appendix Figure 1 To be continued Figure 7 This application will be described in further detail below.
[0035] In one embodiment, the oxygen-filling cycle test equipment includes a processing chamber 1, a circulation mechanism 2, a support mechanism 3, and an adjustment mechanism 4. The processing chamber 1 has a receiving space 11, an air inlet 12, and an air outlet 13. The air inlet 12 communicates with the bottom of the receiving space 11, and the air outlet 13 communicates with the receiving space 11. The circulation mechanism 2 is connected to both the air inlet 12 and the air outlet 13, and is used to fill the receiving space 11 with the gas for testing and collect the tested gas. The support mechanism 3 is located within the receiving space 11 and connected to the processing chamber 1; the support mechanism 3 supports the gas cylinder to be tested. The regulating mechanism 4 is located within the accommodating space 11. The regulating mechanism 4 includes an regulating component 41 and a speed reducer 42. The regulating component 41 is positioned below the support mechanism 3 and includes a buffer component 411 and a diffuser 412. The buffer component 411 is connected to the processing chamber 1, with its buffer wall 4111 facing the air inlet 12. The diffuser 412 is connected to the side of the buffer component 411 away from the buffer wall 4111. The buffer component 411 and the diffuser 412 cooperate to disperse the agglomerated gas entering the processing chamber 1 from the air inlet 12 along the buffer component 411 and the diffuser 412. The speed reducer 42 is spaced above the regulating component 41 and connected to the processing chamber 1. The speed reducer 42 is used to reduce the velocity of the gas dispersed by the regulating component 41.
[0036] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 The processing chamber 1 has a rectangular hollow structure and can use oxygen as the gas. An air inlet 12 is located on the side wall of the bottom interior of the processing chamber 1, and an air outlet 13 is also located on the side wall of the bottom interior of the processing chamber 1. A circulation mechanism 2 is installed on the outer side of the processing chamber 1, connecting the air inlet 12 and the air outlet 13 in series via a pipeline loop. A support mechanism 3 is located in the center of the accommodating space 11, used to stably place and support the gas cylinder to be tested. An adjustment mechanism 4 includes a multi-stage airflow processing structure, with an adjustment component 41 located at the bottom of the processing chamber 1, corresponding to the air inlet 12. A buffer 411 has a plate-shaped impact-resistant structure, with a buffer wall 4111 that is a flat plate facing the air inlet 12. A diffuser 412 can be connected to the side of the buffer 411 away from the buffer wall 4111 using a U-shaped tubular structure. A deceleration component 42 is plate-shaped and located corresponding to the support mechanism 3.
[0037] The oxygen-filling cycle test equipment incorporates an adjustment mechanism 4 within the accommodating space 11 of the processing chamber 1. The adjustment component 41 within the adjustment mechanism 4 is located below the support mechanism 3, ensuring that the agglomerated gas entering the processing chamber 1 from the inlet 12 first contacts the adjustment component 41. The buffer wall 4111 of the buffer component 411 faces the inlet 12, providing initial physical shielding and buffering of the concentrated, high-speed agglomerated gas, dispersing the initial kinetic energy of the airflow. A diffuser 412 is connected to the side of the buffer component 411 away from the buffer wall 4111. The cooperation between the buffer component 411 and the diffuser 412 disperses the buffered gas in various directions, altering the original jet state of the gas. Decelerating components 42 are spaced above the adjustment component 41 to reduce the rising velocity of the gas after dispersion by the adjustment component 41, resulting in smoother gas flow. The adjustment component 41 and the reduction component 42 work together to prevent high-speed agglomerated gas from directly impacting the gas cylinder under test, preventing excessive oxidation on the windward side of the cylinder and the formation of fluid dead zones on the leeward side, and promoting the formation of a uniform laminar flow envelope within the containment space 11, thereby improving the accuracy of the oxygen filling cycle test results. This solves the technical problem in the prior art where direct airflow impact on the gas cylinder under test easily causes test blind zones and errors.
[0038] In one embodiment, the first direction X is vertical, and the second direction Y is the direction in which gas enters the processing chamber 1. The buffer member 411 is arranged along the first direction X, and the buffer wall 4111 is arranged perpendicular to the second direction Y. The diffuser 412 is connected to the buffer member 411 and extends away from the buffer wall 4111 along the second direction Y. The diffuser 412 has a guide groove 4121 that extends along the second direction Y and communicates with the receiving space 11. The guide groove 4121 is used to guide the gas to disperse along the diffuser 412. The deceleration member 42 and the processing chamber 1 are connected to a deceleration chamber 43. The deceleration member 42 has a plurality of vent holes 421 that are arranged through the second direction Y. The plurality of vent holes 421 communicate with the deceleration chamber 43. The deceleration member 42 is used to slow down the speed of the gas flowing through the deceleration chamber 43.
[0039] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 7The vertical direction is set as the first direction X, and the direction in which the gas enters the processing chamber 1 horizontally is set as the second direction Y. A buffer member 411 is connected to the bottom of the processing chamber 1 along the first direction X. The windward buffer wall 4111 has a flat vertical surface that intersects perpendicularly with the trajectory of the gas entering from the air inlet 12. Both the buffer member 411 and the diffuser 412 are arranged along a straight line parallel to the second direction Y. A guide groove 4121 is opened along the second direction Y and passes through the diffuser 412 along the first direction X. The deceleration member 42 is a square plate arranged along the first direction X. The deceleration member 42 has multiple vent holes 421 passing through along the second direction Y. Both ends of the deceleration member 42 along the first direction X are connected to the processing chamber 1 and form a deceleration chamber 43 around the processing chamber 1.
[0040] A buffer member 411 is positioned along the first direction X, with its buffer wall 4111 perpendicular to the second direction Y in which the gas enters. The buffer member 411 is used to receive and block the high-speed gas entering from the front over a large area. A diffuser 412 extends along a straight line parallel to the second direction Y and has a guide groove 4121. The guide groove 4121 guides the gas after it changes direction and forces the gas to disperse outward along the contour of the diffuser 412. The deceleration chamber 43 provides a space for the gas to reside, and multiple vents 421 on the decelerator 42 refine and divide the converged gas. When the airflow passes through the vents 421, mutual friction occurs, slowing down the rising speed of the gas flowing through the deceleration chamber 43 and improving the uniformity of gas distribution.
[0041] In one embodiment, the adjustment component 41 further includes a support member 413, which is located on the side of the diffuser 412 away from the buffer member 411 along the second direction Y. The support member 413 is connected to the diffuser 412 and the processing box 1 respectively. The support member 413 is at least partially perpendicular to the second direction Y and is used to disperse the gas passing through the diffuser 412.
[0042] In this embodiment, refer to Figure 1 and Figure 3 The support member 413 can be made of bent sheet material and is connected to the diffuser 412 on the side away from the buffer member 411 along a straight line parallel to the second direction Y. The support member 413 forms a baffle section disposed along the first direction X, and the orientation of the baffle section is set towards the residual airflow sliding along the surface of the diffuser 412.
[0043] The support member 413 is located at the end of the diffuser 412 away from the buffer member 411. It serves to connect the diffuser 412 to the processing box 1 and improve the overall structural stability of the adjustment assembly 41. At the same time, the support member 413 is at least partially perpendicular to the second direction Y of gas entry, which can provide secondary obstruction to the residual airflow flowing out along the edge of the diffuser 412. The support member 413 forces the gas to change its flow trajectory again at the end, dispersing the gas that has passed through the diffuser 412, avoiding excessive concentration of local airflow, and ensuring the homogenization of the flow field.
[0044] In one embodiment, the third direction Z is perpendicular to the first direction X and the second direction Y. The adjustment mechanism 4 includes two speed reducers 42 and a plurality of adjustment components 41. The plurality of adjustment components 41 are arranged at equal intervals along the third direction Z. The two speed reducers 42 are arranged at intervals along a straight line parallel to the second direction Y.
[0045] In this embodiment, refer to Figure 1 and Figure 3 Multiple adjustment components 41 are arranged at equal intervals along the third direction Z at the bottom of the processing box 1, corresponding to the position of the air inlet 12. The multiple adjustment components 41 form a comb-shaped airflow interception array. Two speed reducers 42 are arranged at intervals along a straight line parallel to the second direction Y, and the distance between the two speed reducers 42 is greater than the length of the adjustment components 41 along the second direction Y.
[0046] Multiple regulating components 41 are arranged at equal intervals along the third direction Z, forming an array-like gas buffer and dispersion area at the bottom of the processing chamber 1, ensuring that the wide airflow entering from the inlet 12 is treated to the same degree in all sections. Two deceleration components 42 are arranged at intervals along a straight line parallel to the second direction Y, causing the gas to undergo multiple stages of obstruction during its ascent. The multi-layered, staggered spatial layout enhances the ability to block and regulate airflow, making the gas flow within the entire containment space 11 smoother and without dead zones.
[0047] In one embodiment, the support mechanism 3 includes a support member 31 and a connector 32. The connector 32 is disposed inside the accommodating space 11 and connected to the deceleration member 42. The connector 32 is spaced apart from the adjustment component 41. The support member 31 is disposed inside the accommodating space 11 and slidably connected to the connector 32. The support member 31 is used to support the gas cylinder to be tested.
[0048] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3The connector 32 adopts a straight rod-shaped structure with a groove, and is connected to the reducer 42. The support 31 adopts a mesh tray, and a matching connector 32 slide bar is provided at the edge of the support 31. The support 31 is slidably connected to the connector 32 via the groove, and the support 31 can slide along the third direction Z under the push and pull of external force.
[0049] Connector 32 is connected to reducer 42 and spaced apart from adjustment assembly 41. Utilizing the structural space at the bottom of processing box 1, it ensures the stability of support mechanism 3 without interfering with gas buffering and diffusion. Support 31 and connector 32 are slidably connected, allowing users to flexibly adjust the position of support 31 within the accommodating space 11 according to the size of the gas cylinder to be tested or testing requirements. The movable support mechanism 3 not only facilitates the handling of gas cylinders but also enhances the equipment's adaptability to test samples of different specifications.
[0050] In one embodiment, the processing box 1 further includes a heat dissipation hole 14, a heat dissipation structure 15, and a receiving cavity 16. The receiving cavity 16 is connected to the receiving space 11 and is used to receive the circulation mechanism 2. The receiving cavity 16 is connected to the heat dissipation hole 14, and the heat dissipation structure 15 is connected to the processing box 1 at the position corresponding to the heat dissipation hole 14.
[0051] In this embodiment, refer to Figure 1 , Figure 3 and Figure 4 The accommodating space 11 and the accommodating cavity 16 are arranged along a straight line parallel to the second direction Y, and the accommodating cavity 16 is connected to the heat dissipation hole 14. The heat dissipation structure 15 adopts a heat dissipation module with louvers, and the heat dissipation structure 15 is directly nested and installed on the heat dissipation hole 14. The accommodating cavity 16 is connected to the accommodating space 11 through the air inlet 12, and the circulation mechanism 2 is set inside the accommodating cavity 16 and connected to the processing box 1.
[0052] The processing chamber 1 has a receiving cavity 16 to house the circulation mechanism 2, isolating the circulation mechanism 2 from the external environment, protecting it from external impurities, and making the overall structure more compact. The receiving cavity 16 is connected to the receiving space 11, shortening the gas transmission path and reducing pressure loss during gas transmission. The heat dissipation holes 14 work in conjunction with the heat dissipation structure 15 to promptly dissipate the heat generated by the circulation mechanism 2 during operation from the processing chamber 1, preventing the internal temperature of the processing chamber 1 from becoming too high and affecting the service life of the circulation mechanism 2 and the temperature stability of the testing environment.
[0053] In one embodiment, the adjusting mechanism 4 further includes a first isolation plate 44 and a second isolation plate 45, which are spaced apart and connected to the processing box 1 to divide the receiving cavity 16 into a first cavity 161, a second cavity 162, and a third cavity 163 that are interconnected. The circulation mechanism 2 includes an oxygen generating component 21 and a circulation component 22. The oxygen generating component 21 is disposed inside the first cavity 161 and connected to the first isolation plate 44, and the circulation component 22 is disposed inside the third cavity 163 and connected to the processing box 1. The oxygen generating component 21 and the circulation component 22 are connected.
[0054] In this embodiment, refer to Figure 1 and Figure 4 Both the first isolation plate 44 and the second isolation plate 45 are made of sturdy metal plates. Both are arranged along the third direction Z. The first isolation plate 44 is spaced above the second isolation plate 45 along a straight line parallel to the first direction X. The first isolation plate 44 and the second isolation plate 45 divide the receiving cavity 16 into three independent compartments with communicating channels from top to bottom: the upper first cavity 161, the middle second cavity 162, and the bottom third cavity 163. The oxygen generating assembly 21 is connected to the first isolation plate 44 above the first direction X. The circulation assembly 22 is located inside the third cavity 163 and connected to the processing box 1. The oxygen generating assembly 21 and the circulation assembly 22 are connected through a pressure-resistant hose passing through the second cavity 162.
[0055] The first and second partition plates 44 and 45 divide the receiving cavity 16 into three interconnected chambers: a first chamber 161, a second chamber 162, and a third chamber 163. This regulates and guides the airflow channels within the receiving cavity 16. The cooperation of the first and second partition plates 44 and 45 ensures that the gas within the receiving cavity 16 flows orderly along a preset path, achieving uniform gas distribution. The oxygen generating component 21 and the circulation component 22 are respectively located inside the independent first chamber 161 and third chamber 163. This prevents the gas flowing through the oxygen generating component 21 and circulation component 22 from directly impacting the processing box 1, while also avoiding mutual interference during the operation of each component. This improves space utilization and increases the efficiency of gas generation and circulation.
[0056] In one embodiment, the oxygen generating assembly 21 includes a base plate 211, a fastener 212, a raised platform 213, an air circulation pipe 214, a transport pipe 215, and a hydraulic tank 216. The base plate 211 is connected to the first isolation plate 44. The fastener 212 is connected to the base plate 211 and the raised platform 213 respectively. The raised platform 213 is connected to the air circulation pipe 214. The air circulation pipe 214 is connected to the transport pipe 215 and the hydraulic tank 216 respectively.
[0057] In this embodiment, refer toFigure 4 and Figure 5 The oxygen generating assembly 21 also includes an outer shell 217 and a cooling fan 218. A base plate 211 is connected to the top of the first isolation plate 44 along the first direction X. A fastener 212 is welded to the top of the base plate 211 along the first direction X. A support frame 213 is snapped onto the top of the fastener 212 along the first direction X. An air circulation pipe 214 is connected to the top of the support frame 213 along the first direction X. The outer shell 217 is connected to the outer surface of the air circulation pipe 214 and the transport pipe 215. The cooling fan 218 is connected to the air circulation pipe 214. The air circulation pipe 214 is connected to the transport pipe 215 and the hydraulic tank 216, respectively. The oxygen generating assembly 21 controls the airflow circulation through the air circulation pipe 214 and the cooling fan 218, ensuring stable gas preparation and distribution. The optimized design of the hydraulic tank 216 and the outer shell 217 optimizes the airflow path, ensuring stable pressure and temperature during gas flow and improving oxygen generation efficiency.
[0058] The raised platform 213 is connected to the base plate 211 via fasteners 212, facilitating the installation, disassembly, and maintenance of the oxygen generating assembly 21. Simultaneously, the raised platform 213 supports the air circulation pipe 214 at a certain height, providing ample bottom space for gas flow. The air circulation pipe 214 connects to the transport pipe 215 and the hydraulic tank 216, forming a closed and smooth oxygen generation and delivery loop. The hydraulic tank 216 stabilizes the gas pressure, and the air circulation pipe 214 guides the prepared gas into the transport pipe 215, ensuring the continuity of the oxygen generation process and the stability of the gas output pressure.
[0059] In one embodiment, the circulation component 22 includes a wind pusher frame 221, a support buffer column 222, a bidirectional wind pusher pipe 223, a gas release pipe 224, a transfer storage pipe 225, and a gas delivery pipe 226. The wind pusher frame 221 is connected to the second isolation plate 45. The support buffer column 222 is connected to the wind pusher frame 221 and the bidirectional wind pusher pipe 223 respectively. The gas release pipe 224 is connected to the bidirectional wind pusher pipe 223. The transfer storage pipe 225 is connected to the gas release pipe 224.
[0060] In this embodiment, refer to Figure 3 , Figure 4 and Figure 6 The circulation component 22 is located below the oxygen generating component 21 along the first direction X. The wind pusher 221 is connected to the processing box 1. The wind pusher 221 is connected to the upper part of the first direction X by a support buffer column 222. The support buffer column 222 is connected to the upper part of the first direction X by a bidirectional wind pusher pipe 223. The bidirectional wind pusher pipe 223 is connected to the gas release pipe 224. The gas release pipe 224 is connected to the transfer storage pipe 225. The transfer storage pipe 225 is connected to the gas delivery pipe 226. The gas delivery pipe 226 is connected to the transport pipe 215.
[0061] The wind-driven frame 221 provides a stable mounting base for the entire circulation assembly 22. The support buffer column 222 plays a role in shock absorption and buffering when connecting the bidirectional wind-driven pipe 223, reducing structural vibration caused by fluid impact. The bidirectional wind-driven pipe 223, gas release pipe 224, transfer storage pipe 225, and gas delivery pipe 226 are sequentially connected and docked with the transport pipe 215, forming a complete gas circulation system. The transfer storage pipe 225 plays a role in energy storage and buffering, while the bidirectional wind-driven pipe 223 enhances the gas delivery power, ensuring the smoothness and sufficiency of gas circulation into the containment space 11.
[0062] In one embodiment, the oxygenation cycle test equipment further includes a first protective component 5 and a second protective component 6. The first protective component 5 is connected to the processing box 1 at the position corresponding to the receiving space 11, and the second protective component 6 is connected to the processing box 1 at the position corresponding to the receiving cavity 16.
[0063] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The oxygenation cycle test equipment also includes a door frame 7, a switch handle 8, and a filter base plate 9. The door frame 7 is installed at the position corresponding to the processing chamber 1 and the receiving space 11. The first protective component 5 is hinged and rotatably connected to the processing chamber 1. The switch handle 8 is connected to the side of the first protective component 5 away from the processing chamber 1. The filter base plate 9 is connected to the bottom of the processing chamber 1. The second protective component 6 is a separately removable cover plate, connected to the position corresponding to the receiving cavity 16 in the processing chamber 1.
[0064] The first protective component 5 covers the position corresponding to the processing chamber 1 and the receiving space 11, and the second protective component 6 covers the position corresponding to the processing chamber 1 and the receiving cavity 16. The first protective component 5 and the second protective component 6 physically isolate the receiving space 11 and the receiving cavity 16 from the external environment, respectively. On the one hand, this prevents external dust and impurities from entering the oxygen-filling circulation test equipment and contaminating the test gas; on the other hand, it avoids the safety hazards to operators caused by internal high-pressure gas leakage, thereby enhancing the overall safety and sealing of the equipment.
[0065] The implementation principle of this embodiment is as follows: During use, the operator places the gas cylinder to be tested on the support member 31 of the support mechanism 3. After closing the first protective member 5 and the second protective member 6, the oxygen generating component 21 generates the test gas required for the test, which is pressurized and buffered by the circulation component 22. The gas enters the accommodating space 11 of the processing chamber 1 from the air inlet 12. Under the action of the regulating mechanism 4, the high-speed direct agglomerated airflow is first blocked and dispersed by the buffer member 411 and the diffuser 412 into a sheet-like airflow, and then refined and divided by the deceleration member 42, transforming the jet of sheet-like airflow into a smooth and uniform rising airflow. The uniform airflow layers cover and act on the surface of the gas cylinder for oxidation cycle testing. After the test, the gas is discharged from the air outlet 13 and returns to the circulation mechanism 2 to complete the closed-loop flow, ensuring the continuity of the test and the accuracy of the test results.
[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
