[0002] As a new type of secondary material, batteries have the advantages of high energy density, long life and environmental protection, and are widely used in electric vehicles, energy storage systems and other fields. In the recycling process of batteries, waste batteries need to be disassembled and treated to recover valuable materials. However, during the disassembly process, chemical reactions inside the battery may produce oxygen, and the presence of these oxygen may cause fires or explosions, so real-time monitoring of oxygen solubility is crucial to ensure the safety of the recycling process.

[0004] 1. Electrochemical sensor: measures oxygen concentration through electrochemical reaction, with fast response and high sensitivity, but is easily affected by temperature and humidity, resulting in measurement error;

[0005] 2. Optical sensor: uses spectral analysis technology to measure oxygen concentration, with high precision and high stability, but the equipment is complex and the cost is high, not suitable for on-site use;

[0006] 3. Thermal conductivity sensor: measures oxygen concentration indirectly by measuring the thermal conductivity of the gas, but is greatly affected by other gas components, resulting in inaccurate measurement results.

[0007] Although existing oxygen solubility measurement devices perform well in some fields, there are the following problems in the battery recycling process:

[0008] 1. Poor environmental adaptability: during the battery recycling process, the temperature and humidity of the environment change greatly, and existing sensors are easily affected by these factors, resulting in inaccurate measurement results;

Detailed Implementation

[0029] To make the technical problems, solutions, and advantages of this utility model clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figure 1 As shown, an embodiment of this utility model provides a device for measuring oxygen concentration during battery recycling, including a protective housing 1, which serves as the outer shell of the entire device for installing and protecting internal components. Preferably, the protective housing 1 is made of a corrosion-resistant and high-temperature-resistant material, capable of withstanding the harsh environment during battery recycling. The protective housing 1 has a test gas port 2 and a backflush gas port 3. The test gas port 2 is connected to a first pipeline 4 located inside the protective housing 1. The first pipeline 4 is also connected to the inlet of a filter 5, which filters out dust impurities from the gas being tested, facilitating subsequent oxygen concentration measurement. The outlet of the filter 5 is connected to a test reaction chamber 6 via a second pipeline 7, on which a flow meter 8 and a first solenoid valve 9 are installed. The test reaction chamber 6 serves as the site for oxygen concentration detection, and the flow meter is used to detect the flow rate of the gas in the second pipeline 7, i.e., the flow rate of the gas entering the test reaction chamber 6, to allow for adjustment if the gas flow rate is too high or too low. The first solenoid valve 9 can be closed and opened. When gas needs to be introduced into the test reaction chamber 6, the first solenoid valve 9 is in the open state. When cleaning by backflushing through the backflushing air hole 3, the first solenoid valve 9 is closed.

[0033] In this embodiment, a third pipeline 10 is also provided inside the protective housing 1. The third pipeline 10 is connected to the backflush port 3 and also to the second pipeline 7, with the connection point located between the first solenoid valve 9 and the filter 5 on the second pipeline 7. A second solenoid valve 11 is provided on the third pipeline 10. An inert gas cleaning module, such as a nitrogen cleaning module, is connected to the backflush port 3. During the gas testing process, the second solenoid valve 11 is closed when the first solenoid valve 9 is open. When reverse cleaning is required, the second solenoid valve 11 opens after the first solenoid valve 9 closes, allowing nitrogen to enter the third pipeline 10 from the backflush port 3, and then be transported in reverse along the second pipeline 7 and the first pipeline 4 until the dust and impurities at the filter 5 and the first pipeline 4 are reverse-cleaned and discharged from the test port 2, preventing the weakening of the filter 5's filtration effect from affecting the measurement results when subsequently testing the oxygen concentration of the gas.

[0034] It should be noted that the nitrogen cleaning module maintains continuous pressure. When the second solenoid valve 11 opens, nitrogen can quickly enter the third pipeline 10 and, under pressure, reverse through the filter 5 into the first pipeline 4. Therefore, the first solenoid valve 9 needs to be closed simultaneously to prevent nitrogen from entering the test reaction chamber 6 and affecting the cleaning effect. The first solenoid valve 9 and the second solenoid valve 11 can be controlled by a backflush circuit. For example, the backflush circuit can control the second solenoid valve 11 to open and the first solenoid valve 9 to close every hour. Alternatively, a switch can be set to manually activate the backflush, immediately opening the second solenoid valve 11 and simultaneously closing the first solenoid valve 9 for backflush cleaning.

[0035] In this embodiment, the test reaction chamber 6 is connected to an exhaust fan 12 or an exhaust pump, and is also connected to the outside of the protective housing 1 through an exhaust pipe. A silencer 13 can be installed and connected to the chamber to reduce noise during exhaust. The exhaust fan 12 or exhaust pump continuously provides negative pressure, allowing gas from the first pipe 4 and the second pipe 7 to flow into the test reaction chamber 6 for oxygen concentration measurement. The exhaust fan 12 or exhaust pump also has a built-in regulator to control the suction force and adjust the gas flow rate introduced into the test reaction chamber 6 based on the gas flow rate feedback from the flow meter 8. Specifically, the flow meter 8 is a float flow meter.

[0036] In this embodiment, an oxygen sensor 14 is installed inside the test reaction chamber 6. Specifically, the oxygen sensor 14 is a zirconia-type oxygen sensor, which is based on the Nernst equation and features high sensitivity and fast response speed. Simultaneously, the system also includes a data processing module with data correction capabilities, capable of correcting oxygen concentration based on temperature changes to improve measurement accuracy.

[0037] At the same time, such as Figure 2As shown, in this embodiment, a display screen 15 is also provided on one outer surface of the protective housing 1. The display screen 15 can display relevant data such as oxygen concentration and gas flow rate. Simultaneously, a power switch 16, a cleaning switch 17, and a calibration switch 18 are also provided on one side of the display screen 15, used to turn the device on or off, manually turn the cleaning function on or off, and manually turn the calibration function on or off, respectively. In addition, an alarm 19 is also provided on the protective housing 1. When abnormal oxygen concentration data is detected, the alarm 16 will trigger an audible and visual alarm (or connect to other alarm units, mobile APP, etc.) to enable the testing personnel to promptly detect and address abnormal changes in oxygen concentration, thus preventing safety hazards.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. 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 application should be determined by the appended claims.
