Description

Technical Field

[0001] This utility model relates to the field of industrial oxygen production technology, specifically to an oxygen purity detection device for use in industrial oxygen generators. Background Technology

[0002] In centralized gas supply systems that combine industrial oxygen production with natural gas combustion, oxygen purity must be strictly maintained within a specific range of 93.5% to 99.2% to ensure efficient and stable combustion. These systems continuously deliver generated oxygen directly to a centralized oxygen supply network via industrial oxygen production equipment, which typically includes multiple independently operating supply pipelines. To ensure consistent purity across all pipelines and prevent decreased combustion efficiency or safety hazards due to purity deviations, regular oxygen purity testing of each pipeline is necessary. Existing testing methods generally rely on sampling from fixed oxygen storage containers for analysis. However, in industrial oxygen production environments, oxygen is directly input into the supply system in a flowing state, with no static storage for sampling. Therefore, testing must be performed at the output end of the supply pipeline. In practice, operators must use the same oxygen purity detector to test each pipeline sequentially. Due to the lack of dedicated quick-connect interfaces at pipeline connection points, each test requires a complex procedure: including closing relevant valves, manually disassembling existing pipeline connections, installing the testing equipment, waiting for the airflow to stabilize, and reconnecting the pipeline after measurement. This process is not only cumbersome and time-consuming, but also prone to loosening of connections or failure of seals due to frequent disassembly and assembly, increasing the risk of oxygen leakage. It may also introduce human error, affecting the reliability of test results. The problem of low testing efficiency is particularly pronounced in multi-pipeline systems, making it difficult to meet the demands of rapid and frequent purity monitoring in industrial settings, severely restricting the continuity and efficiency of overall production operations.

[0013] 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.

[0014] In centralized oxygen and natural gas supply systems, industrial oxygen production environments directly input oxygen into the centralized oxygen supply system. For oxygen purity testing of multiple supply pipelines, the same equipment is usually used to test each pipeline sequentially to ensure data consistency. However, this testing method involves frequent equipment disassembly and reassembly operations, resulting in redundant testing procedures, extended testing cycles, and reduced real-time monitoring capabilities of the system. Among these, the sealing process and equipment switching during testing have become key bottlenecks affecting operational efficiency.

[0015] For example, in the centralized gas supply system of an industrial oxygen plant, there are multiple oxygen output pipelines connected to the combustion equipment. When operators use a single oxygen purity detector to test each pipeline, they need to disassemble the detector and reinstall it on different pipelines in sequence. This process involves removing and installing the sealing caps and disassembling and connecting the joints multiple times. Furthermore, oxygen leakage or external contaminants may easily occur during the disassembly and reassembly process, which may lead to deviations in the test results and system interruption. Therefore, the cumbersome nature of the testing operation directly affects the system's ability to continuously monitor oxygen purity.

[0016] If the above problems are not solved, the inefficiency of oxygen purity detection will lead to untimely control of the combustion process, which may cause flame instability, reduced energy utilization and potential safety risks, adversely affecting the reliability and safety of the system. In particular, the purity anomalies caused by detection delays cannot be identified in time, further exacerbating the uncertainty of system operation.

[0017] In this regard, such as Figures 1 to 4As shown, this application proposes an oxygen purity detection device for an industrial oxygen generator, including a detection tube, a connector one, an oxygen purity detector, and a connector two. Connector one is connected to the oxygen output pipeline of the industrial oxygen generator. One end of the detection tube is connected to connector one, and the other end of the detection tube is connected to the detection inlet of the oxygen purity detector. Connector one and connector two are configured to cooperate. Connector one includes a connecting tube, a partition one, a slide rod, a sleeve rod, a sealing ball, and a spring. A hemispherical cavity is provided inside one end of the connecting tube, and an outlet connected to the outside is provided at the top of the hemispherical cavity. The sealing ball is slidably disposed inside the connecting tube, and the sealing ball is in contact with the hemispherical cavity. The connecting pipe has a sealed fit with a partition plate fixed inside the other end. A sliding rod is positioned at the center of the partition plate, directly opposite the center of the sealing ball. A sleeve rod is slidably fitted onto the sliding rod. The end of the sleeve rod away from the partition plate is fixedly connected to the sealing ball. A spring is installed between the end of the sleeve rod facing the partition plate and the partition plate. The inner diameter of the connecting pipe is larger than the diameter of the sealing ball. A slot is provided on the sealing ball directly opposite the air outlet. The end of the connecting pipe near the partition plate is connected to the oxygen output pipe of the industrial oxygen generator. The second connector includes a sleeve, a second partition plate, and a plug rod. One end of the sleeve is sealed to the end of the connecting pipe near the sealing ball. The second partition plate is located inside the sleeve. The insert rod is installed at the center of the side of the partition plate facing the sealing ball, and the insert rod mates with the slot. The other end of the sleeve is connected to the detection tube, and a sealing cap is provided on the end of the connecting tube near the sealing ball. When not in use, the sealing cap seals the opening of the connecting tube. At the same time, connector one mates with the oxygen output pipe of the industrial oxygen generator to seal the connection port. The spring force causes the sleeve to move the sealing ball against the surface of the hemispherical cavity, forming a pressure-sealing contact surface, thus preventing the risk of oxygen leakage from the connecting tube. Connector two is connected to the detection tube for mates with connector one. When oxygen purity testing is required... During testing, first remove the sealing cap from the connecting pipe. Then, press the second connector against the first connector, and press the second connector against the connecting pipe to insert the rod into the slot. This pushes the sealing ball into the connecting pipe, causing the contact surface between the sealing ball and the hemispherical cavity to separate. This allows oxygen to flow through the connecting pipe, out of the outlet, and into the oxygen purity detector through the detection tube for oxygen purity testing. After testing, simply remove the second connector from the first connector and seal the connecting pipe at that point with the cap. The detector can then be used to test the oxygen purity of other oxygen output pipes, improving overall work efficiency.

[0018] In the field of oxygen purity testing for industrial oxygen generators, traditional methods are cumbersome and inefficient due to the frequent disassembly and reassembly of testing equipment for multiple gas supply lines. This application addresses this problem by providing a testing device, in which the mating mechanism of connector one and connector two constitutes the core solution. In practical applications, the sealing fit between the sealing ball and the hemispherical cavity refers to the gas blockage achieved through the tight contact between the spherical surface and the cavity surface. This can be achieved by using a metal sealing ball with a precision-ground cavity, or by using a ball with a polytetrafluoroethylene coating to enhance the sealing performance, primarily used to prevent oxygen leakage when no external force is applied. Furthermore, the elastic force of the spring is used to drive the sealing ball to return to its original position. The spring can be designed as a helical compression spring or a disc spring, with its elastic coefficient selected according to the system's operating pressure range to ensure that the sealing ball reliably contacts the cavity surface. Thus, the design of the connecting pipe's inner diameter being larger than the sealing ball's diameter provides the necessary space for the axial movement of the sealing ball. Specifically, the difference between the inner diameter and the ball diameter is set to allow the sealing ball to slide freely within the connecting pipe without jamming. For example, the engagement of the insert rod and slot is used to precisely control the displacement of the sealing ball. The slot can be a cylindrical blind hole or through hole structure, and the insert rod is correspondingly designed as a matching cylinder or frustum, thereby pushing the sealing ball out of the cavity when the second connector presses against it. Specifically, the engagement of the slide rod and sleeve rod is set to guide the sealing ball to move in a straight line. The surface of the slide rod can be chrome-plated to reduce frictional resistance, or a linear guide pair structure can be used to improve movement stability. The core innovation of this application lies in the rapid switching and automatic sealing of the detection process achieved through the synergy of the above features: when the second connector presses against the first connector, the insert rod inserts into the slot and pushes the sealing ball to move, opening the oxygen channel; after the second connector is removed, the spring force automatically drives the sealing ball to reset, restoring the sealing state. This avoids the repeated disassembly and assembly steps in traditional detection, allowing the same detector to be continuously applied to multiple oxygen output pipelines, thereby simplifying the operation process. As a preferred embodiment, the sealing cap is used to physically seal the opening of the connecting pipe in the non-detection state. It can adopt a threaded cap or quick-release buckle structure to prevent the intrusion of external contaminants.

[0019] In the oxygen purity testing process of an industrial oxygen generator, this device achieves rapid switching and automatic sealing functions through the cooperation mechanism of connector one and connector two. Connector one is installed on the oxygen output pipeline of the industrial oxygen generator. Its internal structure includes a connecting pipe, a partition one, a sliding rod, a sleeve rod, a sealing ball, and a spring. One end of the connecting pipe has a hemispherical cavity with an outlet at the top that connects to the outside. The sealing ball is slidably positioned inside the connecting pipe and forms a sealing fit with the hemispherical cavity. The other end of the connecting pipe is fixedly installed with partition one. A sliding rod is positioned at the center of partition one, and a sleeve rod is fitted onto the sliding rod with one end fixedly connected to the sealing ball. The spring is located between the sleeve rod and partition one. Connector two consists of a sleeve, partition two, and a plug rod. One end of the sleeve is sealed to the end of the connecting pipe near the sealing ball. Partition two is placed inside the sleeve, and the plug rod is fixed to the center of partition two facing the sealing ball and engages with a slot on the sealing ball. In the non-testing state, the sealing cap covers the opening of the connecting pipe. The spring force causes the sleeve rod to move the sealing ball tightly against the surface of the hemispherical cavity, forming a pressure-sealing contact surface, effectively preventing oxygen leakage. When testing is required, the operator removes the sealing cap, presses connector two against connector one, inserts the insert rod into the slot, and pushes the sealing ball to move axially along the slide rod, causing the sealing ball to separate from the hemispherical cavity. Oxygen flows into the oxygen purity detector through the outlet and the detection tube to complete the purity analysis. After the test is completed, connector two is removed, and the spring automatically resets, pushing the sealing ball back to its position and re-establishing the sealing state. The same testing procedure can then be performed on other oxygen output pipelines.

[0020] Furthermore, in a specific embodiment, when performing purity testing on an oxygen output pipeline of an industrial oxygen generator, the operator first removes the sealing cap, then aligns connector two with connector one and applies axial pressure. The precise fit between the insert and the slot guides the sealing ball to move smoothly along the slide rod, thereby reliably opening the oxygen channel and ensuring that oxygen flows stably through the detection tube into the oxygen purity detector. This process does not require disassembling or reconnecting the pipeline; the channel opening is triggered simply by the pressure action of connector two, significantly simplifying the operation steps.

[0021] Therefore, this technical solution achieves rapid connection and automatic reset of the detection process through the synergistic effect of connector one and connector two, avoiding the cumbersome operation caused by repeated disassembly and assembly in traditional methods. It enables the same detector to efficiently switch to multiple oxygen output pipelines for continuous detection. At the same time, the spring-driven sealing ball reset mechanism and the double protection of the sealing cover ensure the system's sealing performance in non-detection states, effectively eliminating the risk of oxygen leakage, thereby improving overall detection efficiency and operational reliability. Specifically, in some embodiments of this application, a spring is proposed to be installed between the sleeve rod and the partition to provide elastic force to reset the sealing ball and maintain the seal. However, in its implementation, due to the lack of a fixed structure, the spring is prone to displacement or falling off during operation, which leads to the sealing ball not being able to reset accurately, causing the risk of oxygen leakage or inaccurate detection results.

[0022] In this regard, this application further proposes that a limiting annular groove 1 is provided on one end face of the sleeve rod facing the partition 1, one end of the spring is provided in a limiting annular groove 2, the other end of the partition 1 is provided in a limiting annular groove 2, and the other end of the spring is provided in a limiting annular groove 2.

[0023] Among them, the limiting ring groove one refers to the annular groove structure set on the end face of the sleeve rod, which can be realized by using a groove shape with a circular or rectangular cross section. Its purpose is to constrain the end of the spring to prevent it from coming off axially or radially. The limiting ring groove two refers to the annular groove structure set on one end face of the partition plate. It can be realized by using the same or different groove shape and size as the limiting ring groove one. Its purpose is to stabilize the other end of the spring and maintain the installation alignment.

[0024] Specifically, through the synergistic effect of the double limiting structure of limiting ring groove one and limiting ring groove two, the spring is precisely constrained in a fixed axial path. When the sleeve slides on the slide rod, the two ends of the spring are respectively embedded in limiting ring groove one and limiting ring groove two, which effectively avoids spring displacement caused by lateral force or vibration, and ensures that the spring force is always uniformly transmitted along the axial direction. This ensures that the sealing ball is accurately reset to the sealing position of the hemispherical cavity under the action of the spring force, and maintains the tight fit of the sealing contact surface.

[0025] As a specific implementation method, the solution of this application is implemented as follows: the limiting ring groove one can be designed as an annular groove, the depth of which is sufficient to accommodate the end of the spring and limit radial displacement; the limiting ring groove two is correspondingly set on the end face of the partition plate one, forming a matching limiting fit with the limiting ring groove one, so that the spring always moves along the axis of the slide rod during repeated compression and rebound, and can maintain a stable installation state without additional fasteners.

[0026] Through the above solution, this application effectively solves the problem that the spring is prone to displacement or detachment during frequent testing operations, ensures the reliability of the sealing ball reset, avoids the risk of oxygen leakage due to seal failure, and thus improves the accuracy of the oxygen purity testing process and the service life of the device. Specifically, in some embodiments of this application, an arc-shaped sealing ring is provided on the inner wall of the hemispherical cavity to improve sealing reliability. However, in the process of its implementation, since the sealing ball is in direct contact with the inner wall of the hemispherical cavity, it is easily affected by oxygen flow impact, temperature changes or mechanical wear during long-term operation of industrial oxygen generators, resulting in tiny gaps on the contact surface, causing the risk of oxygen leakage. This not only affects the accuracy of purity detection, but may also cause safety hazards due to leakage. Especially in multi-pipeline centralized gas supply systems, leakage problems will further reduce detection efficiency and system stability.

[0027] In this regard, this application further proposes that the inner wall of the hemispherical cavity is provided with an arc-shaped sealing ring that fits against the inner wall of the hemispherical cavity.

[0028] Among them, the arc-shaped sealing ring refers to an elastic sealing element that precisely matches the curvature of the inner wall of the hemispherical cavity. It can be made of elastic materials such as rubber, silicone or polytetrafluoroethylene. Its purpose is to fill potential gaps through uniform elastic deformation and prevent oxygen leakage. The geometry of the sealing ring fits perfectly with the inner wall of the hemispherical cavity, avoiding the problem of local stress concentration that is easy to occur when traditional planar seals are in contact with the spherical surface.

[0029] Specifically, when the sealing ball abuts against the hemispherical cavity under the action of the spring, the arc-shaped sealing ring undergoes uniform elastic deformation, tightly filling the gap between the sealing ball and the inner wall of the cavity, forming a continuous sealing interface. Due to the spherical characteristics of the hemispherical cavity, the curved surface fitting method of this sealing ring effectively avoids point contact or line contact problems, thereby maintaining a stable seal under dynamic conditions of installation or disassembly of the detection device. At the same time, the elastic material of the sealing ring adapts to vibration and temperature fluctuations in the industrial environment, and can still maintain a reliable seal when the pressure of the oxygen generator output pipeline changes, ensuring smooth oxygen flow during detection and completely isolating leakage paths when not in detection mode.

[0030] As a preferred embodiment, the solution of this application is specifically implemented as follows: the arc-shaped sealing ring can be made of fluororubber, and its shape is completely fitted to the inner wall of the hemispherical cavity. During installation, it is embedded in the groove of the inner wall of the hemispherical cavity to ensure uniform contact with the surface of the sealing ball.

[0031] Through the above solution, this application effectively solves the problem of minute gaps caused by direct contact between the sealing ball and the hemispherical cavity, significantly reduces the risk of oxygen leakage, improves the accuracy of oxygen purity detection and operational safety, and enhances detection efficiency and system stability, especially in multi-pipeline centralized gas supply systems. Specifically, in some embodiments of this application, optimization of the sealing structure is proposed to improve the sealing performance of the device. However, in the process of its implementation, when the connecting pipe port is matched with the industrial oxygen generator pipe and connector, due to the presence of small gaps or uneven surfaces between the metal parts, oxygen is prone to leak from the interface under high pressure. This not only affects the accuracy of purity detection, but may also introduce external impurities and cause data deviation. At the same time, the sealing reliability decreases after repeated disassembly and assembly, increasing the operational risk.

[0032] In this regard, this application further proposes that a sealing ring 1 is provided at both ends of the connecting pipe, and a sealing ring 2 is provided at the end of the sleeve located away from the sealing ball on the partition 2.

[0033] Among them, sealing ring one refers to the elastic sealing element set at both ends of the connecting pipe. It can be made of rubber, silicone or polytetrafluoroethylene material to make an annular sealing ring. Its purpose is to fill the micro-unevenness of the metal contact surface through elastic deformation and block the oxygen leakage path. Sealing ring two refers to the sealing element set at the end of the inner partition plate two away from the sealing ball. It can be made of the same or different elastic material as sealing ring one to make an annular sealing ring. Its purpose is to form a secondary sealing barrier during the insertion and removal of the joint and compensate for the fit gap between partition plate two and the end face of the connecting pipe.

[0034] Specifically, the solution of this application involves setting a sealing ring 1 at both ends of the connecting pipe. When the connecting pipe mates with the industrial oxygen generator pipe or connector 2, the sealing ring 1 undergoes elastic deformation under assembly pressure, tightly fitting the contact surface and eliminating gaps caused by assembly tolerances or vibration. Simultaneously, a sealing ring 2 is set at the end of the inner partition 2 of the sleeve away from the sealing ball. When connector 2 mates with connector 1, the insertion rod pushes the sealing ball to move when inserted into the slot. The sealing ring 2 withstands reverse pressure at the interface between the sleeve and the connecting pipe, forming an effective seal and preventing oxygen from escaping from the inside of the sleeve. The two sealing rings act independently in different positions while complementing each other, jointly ensuring the integrity of the oxygen flow path and maintaining the purity of the detected gas flow.

[0035] As a preferred embodiment, the solution of this application is specifically implemented as follows: O-rings made of silicone rubber can be set at both ends of the connecting pipe as sealing ring one, and a rectangular cross-section sealing ring made of fluororubber can be set at the end of the sleeve located away from the sealing ball of the partition two as sealing ring two; when the connecting pipe is connected to the industrial oxygen generator pipeline, sealing ring one is compressed and deformed to fill the interface gap; when connector two is engaged with connector one, the insertion rod is inserted into the slot to push the sealing ball to move, and at the same time, sealing ring two forms a seal at the interface between the sleeve and the connecting pipe.

[0036] Through the above solution, this application effectively solves the problem of easy leakage at the connection pipe port under high pressure, avoids inaccurate purity detection and introduction of external impurities due to oxygen leakage, and improves the sealing reliability of the device after repeated disassembly and assembly, and reduces operational risks. In practical applications, some embodiments of this application propose partition one and partition two to support the slide bar and insert bar structure. However, in the implementation process, the partitions hinder oxygen flow, resulting in uneven oxygen flow rate and pressure fluctuations during detection, which affects the accuracy and efficiency of purity detection.

[0037] In this regard, this application further proposes that air holes one is evenly distributed on partition one, and air holes two is evenly distributed on partition two corresponding to the air outlet.

[0038] Among them, vent one refers to multiple through-hole structures set on partition one, which can be realized by circular, square or elliptical holes. Its purpose is to disperse the oxygen flow path and avoid oxygen accumulation and flow obstruction caused by solid partitions. Vent two can be understood as multiple through holes set on partition two, corresponding to the air outlet position. It can be realized by the same or different hole structure as vent one. Its purpose is to guide the airflow distribution evenly and prevent local high speed phenomenon and airflow turbulence.

[0039] Specifically, the solution of this application uses evenly distributed air holes on partition one to allow oxygen to flow through partition one in a dispersed manner, eliminating pressure concentration points caused by the solid structure and ensuring a smooth transition of oxygen flow; at the same time, through evenly distributed air holes on partition two corresponding to the air outlet, oxygen flows out from the air outlet and is evenly diffused to the inlet of the detection tube, avoiding turbulence caused by direct airflow impact, thereby maintaining a continuous and stable flow of oxygen during the detection process and effectively solving the problems of uneven flow rate and pressure fluctuation.

[0040] As a preferred embodiment, the solution of this application is specifically implemented as follows: the air hole one on the partition one can be a plurality of circular holes, evenly arranged in a grid pattern; the air hole two on the partition two can be a plurality of small holes, symmetrically distributed in a ring around the center of the air outlet, so as to achieve uniform diffusion and stable introduction of oxygen flow.

[0041] Through the above-mentioned scheme, this application ensures a stable oxygen flow rate during the detection process, reduces the interference of pressure fluctuations on the detection results, and improves the accuracy of oxygen purity detection and overall work efficiency.

[0042] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
