Description

Technical Field

[0001] This utility model relates to the field of gas analysis, and more specifically, to an oxygen content analysis device. Background Technology

[0002] In all stages of chemical production, the detection of oxygen content in gases is crucial, affecting product quality and production safety. This is especially true during polymerization reactions, where the polymerization reactor needs to be air-free to prevent monomer self-polymerization in trace oxygen conditions. While there are many methods for analyzing trace oxygen content, considering factors such as speed, accuracy, and cost-effectiveness, EMUST has launched the MUST OE1, an online oxygen content analysis system utilizing the fuel electromagnetic method, ensuring real-time and accurate online detection of oxygen content in gases.

[0003] For example, patent (CN213580772U) discloses an online oxygen content analysis device, which includes: a magnetic oxygen analyzer; a multi-path gas mixture pretreatment unit; a multi-path gas mixture switching unit; and a PLC (Programmable Logic Controller)-DCS (Distributed Computer Control System) control unit. This device enables a single magnetic oxygen analyzer to analyze the oxygen content of sample gas mixtures from multiple sampling points according to a program, improving the utilization rate of the magnetic oxygen analyzer, reducing analysis costs, and avoiding the traditional method of manually switching sampling points on-site, thus eliminating the heavy workload of analysis operators. When using the above technology, the following technical problems were found in the existing technology: the installation of the internal analysis device and electrical equipment of the existing oxygen content analysis device is not convenient to adjust and adapt to the installation space as needed. Therefore, we designed an oxygen content analysis device to provide another technical solution to the above technical problems. Utility Model Content

[0014] 3. Beneficial effects

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example:

[0021] Please see Figure 1-10 The device includes a housing 1 and a closing door 2. The closing door 2 is installed on the front of the housing 1, allowing the front of the housing 1 to be opened or closed. When the closing door 2 is open, electrical appliances installed inside the housing 1 can be accessed. A display or controller is installed on the front of the closing door 2, which can analyze the data of electrical control or oxygen content detection in the device in real time. An oxygen concentration device 3 is fixed to the top of one end of the housing 1, which can detect the oxygen content in the outside air. An alarm light 4 is fixed to one end of the top of the housing 1. When the oxygen content is detected by the oxygen concentration device 3, if the detected data is lower or higher than the set threshold in the oxygen concentration device 3, the alarm light 4 will illuminate to issue an alarm. Preferably, the oxygen concentration device 3 consists of an oxygen content sensor and a microcontroller. The oxygen content sensor can detect the oxygen content in the air, and the signal can be transmitted to the microcontroller to control the operation of the alarm light 4.

[0022] Gas delivery mechanisms are installed on the top of the housing 1 and the bottom of one end of the housing 1. These two gas delivery mechanisms allow external air to enter and exit the housing 1, thus achieving air circulation. The gas delivery mechanism includes a fixed shell 5, a filter plate 6, a fan 7, and a limiting component. The fixed shell 5 is fixed to the housing 1, allowing air to circulate within the housing 1 and the fixed shell 5. The fan 7 is installed inside the fixed shell 5, allowing it to rotate. The rotation of the fan 7 allows one of the fixed shells 5 to deliver external air into the housing 1 and the other fixed shell 5 to extract air from the housing 1. The filter plate 6 is slidably connected inside the fixed shell 5, allowing external air to be filtered when it enters the housing 1. Limiting components for positioning the filter plate 6 are installed on both sides of the fixed shell 5, preventing the filter plate 6 from accumulating inside the fixed shell 5. The limiting assembly includes a protective shell 10, a positioning block 11, a displacement drive motor 13, and a displacement threaded rod 14. The protective shell 10 is fixed to the fixed shell 5. The positioning block 11 is slidably connected inside the protective shell 10. The positioning block 11 is slidably connected to the fixed shell 5, so that the positioning block 11 can slide and translate inside the fixed shell 5 and the protective shell 10. One end of the positioning block 11 is provided with a pressing slope 12, so that when the positioning block 11 slides from the inside of the protective shell 10 into the inside of the fixed shell 5, the pressing slope 12 presses and positions the filter plate 6 inside the fixed shell 5. The displacement drive motor 13 is fixed inside the protective shell 10. The output end of the displacement drive motor 13 is connected to the displacement threaded rod 14. The outer side of the displacement threaded rod 14 is threadedly connected to the positioning block 11, so that the rotation of the displacement threaded rod 14 drives the positioning block 11 to slide and translate inside the protective shell 10. A support mechanism 8 is installed inside the housing 1. A mounting plate 9 is positioned on top of the support mechanism 8. The mounting plate 9 can be supported at different heights by the support mechanism 8 at different installation positions inside the housing 1, thus enabling the bottom fixation of installed electrical appliances via the mounting plate 9. The mounting plate 9 is simply placed on top of the support mechanism 8 in contact with the housing. The support mechanism 8 includes a first assembly shell 15, a second assembly shell 16, and connecting blocks 19. Connecting blocks 19 are slidably connected to the interior of both ends of one side of the second assembly shell 16. The connecting blocks 19 are L-shaped and slidably connected to the housing 1, allowing the second assembly shell 16 to... The interior of the housing 1 is connected to the inner wall of the housing 1 via the connecting block 19, thereby positioning the second assembly shell 16 within the housing 1. The two ends of the housing 1 and the side of the second assembly shell 16 are slidably connected to the first assembly shell 15, and the first assembly shell 15 and the second assembly shell 16 are slidably connected, so that the first assembly shell 15 is installed from the front of the housing 1 by sliding. When the first assembly shell 15 enters the interior of the second assembly shell 16, the first assembly shell 15 and the second assembly shell 16 are assembled as a whole inside the housing 1, thereby supporting the bottom of the mounting plate 9 through the first assembly shell 15 and the second assembly shell 16. A brake block 17 is slidably connected inside the top of the first assembly shell 15 on the side away from the second assembly shell 16, so that the brake block 17 can be adjusted up and down by sliding inside the first assembly shell 15. A compression spring 18 is fixed inside the first assembly shell 15 and at the bottom of the brake block 17, so that when the brake block 17 descends, it drives the compression spring 18 to compress. The rebound of the compression spring 18 drives the brake block 17 to rise and reset, thereby positioning the mounting plate 9 located at the top of the first assembly shell 15 and the second assembly shell 16 through the brake block 17. An adjustment mechanism is installed inside the second assembly housing 16. This mechanism adjusts the distance between the two connecting blocks 19 and the position of the first assembly housing 15 inside the second assembly housing 16. The adjustment mechanism includes a limit plate 20, a return spring 21, an adjustment drive motor 22, a first bevel gear 23, a second bevel gear 24, and a bidirectional threaded rod 25. The adjustment drive motor 22 is fixed inside the second assembly housing 16. The output end of the adjustment drive motor 22 is connected to the first bevel gear 23. One side of the first bevel gear 23 is meshed with the second bevel gear 24. The bidirectional threaded rod 25 is fixed inside the second bevel gear 24. The outer side of the bidirectional threaded rod 25 is threaded to the connecting block 19, causing the first bevel gear 23 to drive the bidirectional threaded rod 25 to rotate via the second bevel gear 24, thus adjusting the distance between the two connecting blocks 19 and the position of the first assembly housing 15 inside the second assembly housing 16. The threaded segments with opposite directions of rotation drive the two threaded connecting blocks 19 to move in opposite directions. The ends of the two connecting blocks 19 that are far apart from each other are slidably connected to limit plates 20, so that the limit plates 20 can move closer to or away from the second bevel gear 24 by sliding on the outside of the connecting blocks 19. At the same time, when the connecting blocks 19 move closer to the second bevel gear 24, they can drive the limit plates 20 to move synchronously. The limit plates 20 are slidably connected to the first assembly shell 15, so that the limit plates 20 can enter the first assembly shell 15 on the side inside the second assembly shell 16, making the first assembly shell 15 and the second assembly shell 16 inseparable. A return spring 21 is fixed between the connecting blocks 19 and the limit plates 20, so that when the limit plates 20 slide on the outside of the connecting blocks 19 and move closer to the second bevel gear 24, they can drive the limit plates 20 to compress. Preferably, the limiting plate 20 has a guide slope 26 at the end away from the connecting block 19 and on the side close to the first assembly shell 15. When the first assembly shell 15 enters the second assembly shell 16, the limiting plate 20 slides outside the connecting block 19 by squeezing the guide slope 26, which in turn compresses the return spring 21. When the limiting plate 20 can enter the bidirectional threaded rod 25, the limiting plate 20 is reset and moved by the rebound after being compressed by the return spring 21.

[0023] In use: Before use, adjust the height of the second assembly shell 16 inside the housing 1 according to the different heights of the electrical appliances installed inside the housing 1. At the same time, allow the connecting block 19 to slide and pre-assemble inside the housing 1. At this time, the first bevel gear 23 can be rotated by adjusting the operation of the drive motor 22. The first bevel gear 23 drives the bidirectional threaded rod 25 to rotate through the meshing second bevel gear 24. The rotation of the bidirectional threaded rod 25 drives the two threaded connecting blocks 19 to move, so that the two connecting blocks 19 move away from each other and are positioned inside the housing 1. Then, the first assembly shell 15 is slid in... The housing 1 is assembled inside, and the heights of the first assembly shell 15 and the second assembly shell 16 are aligned. The first assembly shell 15 slides into the second assembly shell 16, and the first assembly shell 15 enters the second assembly shell 16. The guide slope 26 presses the limiting plate 20, and the limiting plate 20 slides on the outside of the connecting block 19. After being compressed by the return spring 21, it rebounds, so that the limiting plate 20 slides and limits the position of the first assembly shell 15 entering the second assembly shell 16, thereby ensuring that the installation of the first assembly shell 15 and the second assembly shell 16 cannot be separated. Then, the mounting plate 9 is slidably placed on top of the first assembly shell 15 and the second assembly shell 16, and at the same time, it is limited by the brake block 17, so that the electrical components are assembled with bottom support through the mounting plate 9, which facilitates the formation of an overall analysis device. When the device is in use, the oxygen concentration device 3 detects the oxygen content in the air. After the structure is detected, if the detected structure is within the set threshold, the value is displayed only on the front of the closed door 2. If the value is lower than the minimum threshold or higher than the maximum threshold, an alarm is triggered by the alarm light 4 while the value is displayed on the front of the closed door 2.

[0024] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
