Description

Technical Field

[0001] The present application relates to the field of gas detection, and in particular to a nitrogen reflux detection device. Background Art

[0002] In modern industrial production, nitrogen is widely used as a protective gas to prevent oxidation and contamination, particularly in semiconductor manufacturing, glass coating, and some specialty chemical processing. The safe operation of nitrogen systems is crucial to the stability of the entire production process and product quality. Therefore, monitoring the nitrogen return path is particularly important to ensure that the nitrogen supply is not interrupted or contaminated.

[0003] Among related technologies, monitoring the nitrogen return path primarily relies on installing nitrogen sensors in nitrogen pipelines. This approach enables real-time monitoring of nitrogen purity and pressure, as well as leak detection. These sensors are typically installed at key locations along the pipeline. Through continuous data feedback, they effectively monitor the entire nitrogen supply system in real time, promptly identifying potential leaks or contamination issues and ensuring a stable nitrogen supply during production.

[0004] Regarding the above technical solution, although effective monitoring of nitrogen quality and leakage can be achieved by installing a fixed nitrogen sensor, the nitrogen sensor is easily affected by the environment when working outdoors. For example, on rainy days or when the location of nitrogen leakage in the nitrogen pipeline is far away from the nitrogen sensor, the nitrogen sensor may not be able to detect nitrogen leakage in a timely manner.

DETAILED DESCRIPTION

[0021] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] Example 1:

[0025] like Figures 1 to 3 As shown, the present application provides a nitrogen reflux path detection device, including a closed box 1, an air blowing fan 2, a nitrogen detection component 3 and an adjustable barrier component 4. The closed box 1 is preset to be sealed on the nitrogen reflux path, and a fan port 11 and an air outlet groove 12 are provided on the closed box 1. The fan port 11 and the air outlet groove 12 are arranged on two end faces of the closed box 1 facing each other.

[0026] By configuring the preset seal of the closed box 1 on the nitrogen return path, and respectively providing a fan port 11 and an air outlet slot 12 on two opposite end faces of the closed box 1, precise control of the nitrogen flow direction and closed management of the monitoring environment are achieved, ensuring that all nitrogen flowing through must pass through the nitrogen detection component 3 for quality inspection.

[0027] The air blowing fan 2 is installed on the fan port 11, and the nitrogen detection component 3 is installed on the air outlet groove 12.

[0028] By installing the air blowing fan 2 on the fan port 11 and fixing the nitrogen detection component 3 on the air outlet slot 12, forced delivery and continuous monitoring of the air flow in the nitrogen reflux path are achieved, thereby improving the response speed and detection accuracy of nitrogen detection.

[0029] The adjustable barrier assembly 4 is arranged on the side wall of the closed box 1 , and the adjustable barrier assembly can slide to cover the nitrogen detection assembly 3 .

[0030] By setting the adjustable barrier component 4 on the side wall of the closed box 1 and enabling the adjustable barrier component 4 to slide to cover the nitrogen detection component 3, the nitrogen detection component 3 is prevented from being wetted by rain, thereby protecting the nitrogen detection component 3 and enhancing the functionality and reliability of the device under different environmental conditions.

[0031] In the embodiment, the closed box 1 is installed with a preset seal on the nitrogen return path to ensure that all nitrogen must pass through the inside of the closed box 1. The two end faces of the closed box 1 are respectively provided with a fan port 11 and an air outlet slot 12. The air blowing fan 2 is installed on the fan port 11 to push the nitrogen through the closed box 1. The nitrogen detection component 3 is installed on the air outlet slot 12 to monitor the quality of the nitrogen flowing out through the air outlet slot 12. The adjustable barrier component 4 is installed on the side wall of the closed box 1 and can slide to cover the nitrogen detection component 3. The detection position is adjusted as needed to adapt to different monitoring requirements and environmental conditions.

[0032] By adopting the design of the nitrogen reflux detection device, the flexibility and accuracy of nitrogen leak detection can be effectively improved. The closed box 1 ensures that the flow direction of nitrogen is controlled, and the use of the air blower 2 enhances the fluidity of nitrogen, ensuring that nitrogen can pass through the nitrogen detection component 3 evenly, thereby improving the stability and efficiency of detection. The adjustable baffle component 4 provides additional environmental adaptability and protection for the nitrogen detection component 3, so that the nitrogen reflux detection device can maintain high efficiency under complex or harsh external conditions, improving the problem that the nitrogen sensor is easily affected by the environment when working outdoors. For example, on rainy days or when the location of nitrogen leakage in the nitrogen pipeline is far away from the nitrogen sensor, the nitrogen sensor has the problem of not being able to detect nitrogen leaks in a timely manner.

[0033] Example 2:

[0034] like Figures 1 to 3 As shown, the adjustable baffle assembly 4 includes a baffle plate 41, a sliding bolt 42, a return spring 43, and a stop nut 44. The baffle plate 41 is provided with a sliding groove 411. The sliding bolt 42 passes through the sliding groove 411 and is threadedly connected to the side wall of the closed box 1 and the stop nut 44. The sliding bolt 42 is used to tighten the baffle plate 41 against the side wall of the closed box 1 to adapt to different nitrogen return path configurations and environmental conditions.

[0035] A return spring 43 is mounted on the sliding bolt 42, with one end of the return spring 43 pressed against the side wall of the closed box 1, and the other end of the return spring 43 pressed against the end of the limit nut 44 facing the closed box 1. The design of the return spring 43 ensures the stability and reliability of the baffle 41, allowing it to automatically return to the preset position after adjustment, ensuring that the baffle 41 can continue to be pressed against the sliding bolt 42 after adjustment and will not accidentally move or detach.

[0036] The baffle plate 41 is provided with a pull ring 412, which is used for the baffle plate 41 to slide on the closed box 1. The introduction of the pull ring 412 allows the operator to easily manually adjust the position of the baffle plate 41 without using additional tools, thereby improving the convenience and speed of operation.

[0037] like Figures 1 to 3 As shown, the nitrogen detection assembly 3 includes a mounting box 31, a nitrogen sensor 32, and a temperature sensor 33. The mounting box 31 is disposed on the enclosed box 1 and mounted on the gas outlet slot 12. By securing the mounting box 31 to the enclosed box 1, the nitrogen sensor 32 and the temperature sensor 33 enable real-time monitoring of the nitrogen quality and ambient temperature in the nitrogen return path.

[0038] Nitrogen sensor 32 and temperature sensor 33 are mounted on mounting box 31, with their sensing ends facing fan port 11. This arrangement ensures that nitrogen sensor 32 can accurately capture nitrogen quality data at the location where nitrogen flows, while temperature sensor 33 provides supplementary information on ambient temperature, providing a basis for comprehensive analysis.

[0039] An exhaust slot 311 is provided on the side of the mounting box 31. When the blower 2 blows the gas within the enclosed box 1 toward the outlet slot 12 and into the mounting box 31, the nitrogen sensor 32 and temperature sensor 33 detect the gas within the enclosed box 1 and exhaust it through the exhaust slot 311. The provision of the exhaust slot 311 effectively prevents gas stagnation and improves the accuracy and efficiency of detection.

[0040] Meanwhile, a display screen 312 is provided on the mounting box 31 and is electrically connected to the nitrogen sensor 32 and the temperature sensor 33. Through the display screen 312, the operator can monitor the nitrogen quality and ambient temperature data in the nitrogen return line in real time, thereby improving the visualization of real-time monitoring and the intuitiveness of operation.

[0041] like Figures 1 to 3 As shown, the closed box 1 is provided with a box drainage groove 13 for draining water. The design of the drainage groove effectively removes liquid that may accumulate on the top of the closed box 1, keeps the device in a dry and clean state, and extends the service life of the device.

[0042] A gas pipe connector 16 is provided on the side wall of the closed box 1. This connector 16 is connected to the nitrogen return path for connection to external devices. This design facilitates the connection of external devices or pipelines, allowing the nitrogen return path detection device to be seamlessly integrated with other equipment or systems, improving application flexibility and versatility.

[0043] In this embodiment, by integrating the adjustable baffle assembly 4, the nitrogen detection assembly 3 and the mounting box 31, accurate monitoring and management of the nitrogen quality and environmental conditions in the nitrogen reflux path are achieved. The adjustable baffle assembly 4 achieves accurate adjustment and stable fixation of the position of the baffle plate 41 through the combination of the baffle plate 41, the sliding bolt 42, the return spring 43 and the limit nut 44, thereby ensuring the reliability and adaptability of the device under various working conditions. The nitrogen detection assembly 3 ensures comprehensive monitoring of the nitrogen quality and ambient temperature through the arrangement of the mounting box 31, combined with the use of the nitrogen sensor 32 and the temperature sensor 33, so that the device can respond to abnormal conditions in a timely manner and take effective measures.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
