Its composition is a core parameter for process control and a key link in process connections, necessitating the detection of electrolyte components. Currently, the main method for determining electrolyte composition is manual sampling followed by laboratory analysis, which suffers from drawbacks such as complex procedures, poor real-time performance, poor representativeness, and low detection frequency. Furthermore, the adoption of automated real-time electrolyte composition detection technology is of great significance for the construction of smart factories. Currently, the main technique for quantitative detection of electrolyte components is chemical titration. However, chemical titration requires a single device to detect only one element, resulting in high operating costs and failing to meet the need for simultaneous detection of multiple components, leading to low detection efficiency.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] The following is for reference. Figures 1-2 Description of an electrolyte component detection system 1 according to an embodiment of the present invention.

[0031] like Figure 1 and Figure 2 As shown, the electrolyte composition detection system 1 according to an embodiment of the present invention includes: a storage device 10, a pipeline assembly 20, and a laser composition analyzer 30. The storage device 10 is used to store electrolyte. The pipeline assembly 20 is connected to both the storage device 10 and the laser composition analyzer 30. The pipeline assembly 20 is used to transport the electrolyte in the storage device 10 to the laser composition analyzer 30. The laser composition analyzer 30 is used to convert the electrolyte into a solid state. The laser composition analyzer 30 is also used to emit a laser to the solid electrolyte to obtain spectral data information of the electrolyte and determine the composition of the electrolyte based on the spectral data information. The laser composition analyzer 30 has a drain port 331, which is selectively opened or closed. The laser composition analyzer 30 is also used to convert the solid electrolyte into a liquid electrolyte so that the liquid electrolyte can be discharged from the laser composition analyzer 30 through the drain port 331.

[0032] It should be noted that current technologies primarily rely on manual sampling followed by laboratory analysis to determine the composition of electrolytes. This approach suffers from drawbacks such as complex procedures, poor real-time performance, low representativeness, and low testing frequency. Furthermore, the adoption of automated real-time electrolyte composition detection technology is crucial for the construction of smart factories. Currently, the main quantitative detection technology for electrolyte components is chemical titration. However, chemical titration requires a single device to detect only one element, resulting in high operating costs, inability to meet the need for simultaneous detection of multiple components, and low detection efficiency.

[0033] Based on this, this application proposes an electrolyte composition detection system 1. The storage device 10 can be an electrolyte storage tank or a high-level tank, etc., used to store electrolyte and provide electrolyte to the electrolyte composition detection system 1. The electrolyte in the storage device 10 is liquid. A pipeline assembly 20 can be connected to the storage device 10 and a laser composition analyzer 30. The pipeline assembly 20 connects the storage device 10 and the laser composition analyzer 30, allowing the electrolyte in the storage device 10 to be transported to the laser composition analyzer 30 via the pipeline assembly 20. The laser composition analyzer 30 can convert the liquid electrolyte into a solid state. The laser composition analyzer 30 can emit a laser beam into the solid electrolyte, which burns the solid electrolyte to generate plasma. The laser composition analyzer 30 can acquire the light signal emitted by the plasma, thereby obtaining the spectral data information of the electrolyte. By analyzing the spectral data information, the composition of the electrolyte can be determined.

[0034] As an example, there can be multiple storage devices 10, which can be used to store different types of electrolytes. These storage devices 10 can be connected in series, and the electrolytes in the series-connected devices can be used in the same process. The electrolytes in the series-connected devices can be mixed and then fed into a laser component analyzer 30, which can determine the composition of the mixed electrolytes, achieving simultaneous detection of multiple electrolytes. Alternatively, the multiple storage devices 10 can be connected in parallel, and the electrolytes in the parallel-connected devices can be used for different processes. The electrolytes in the parallel-connected devices can each be fed into a laser component analyzer 30, which can determine the composition of the electrolytes, achieving multi-point sampling.

[0035] In this embodiment, by transporting the electrolyte in the storage device 10 to the laser component analysis device 30, the laser component analysis device 30 can convert the electrolyte into a solid state. The laser component analysis device 30 can acquire the spectral data information of the electrolyte and determine the composition of the electrolyte based on the spectral data information, thereby achieving the effect of automatic real-time detection of electrolyte composition. Moreover, there can be multiple storage devices 10, which can realize the effect of simultaneous detection of multiple groups of electrolytes and multi-point sampling. It has the advantages of high real-time performance, high representativeness, and high detection efficiency. Furthermore, by converting the electrolyte into a solid state, highly sensitive quantitative detection of electrolyte composition can be achieved, which is beneficial to improving the stability and accuracy of detection.

[0036] The laser component analysis device 30 has a drain port 331 through which liquid can be drained. The drain port 331 can be selectively opened or closed; it opens when liquid drainage is needed and closes when drainage is not required. After completing the electrolyte component detection, the laser component analysis device 30 can convert the solid electrolyte into a liquid electrolyte, which can then be discharged through the drain port 331. By selectively opening or closing the drain port 331, liquid can be selectively discharged from the laser component analysis device 30, thus meeting its drainage requirements.

[0037] As an example, before performing electrolyte component detection, the electrolyte component detection system 1 can be rinsed with the electrolyte to be tested, thereby reducing the probability that other residual liquids in the electrolyte component detection system 1 will affect the detection results. The rinsing electrolyte can be discharged from the laser component analysis device 30 through the drain port 331. After performing electrolyte component detection, the electrolyte component detection system 1 can be rinsed with rinsing water, thereby discharging the tested electrolyte from the laser component analysis device 30. Both the rinsing water and the tested electrolyte can be discharged from the laser component analysis device 30 through the drain port 331.

[0038] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the laser component analysis device 30 may include: a container 31 and a heat exchanger 32. The pipeline assembly 20 is connected to the container 31 and selectively conducts liquid storage device 10 and container 31. The container 31 is connected to the drain port 331. The heat exchanger 32 cooperates with the container 31 to exchange heat so that the electrolyte in the container 31 is converted into a solid or liquid state.

[0039] The piping assembly 20 can be connected to the container 31, allowing electrolyte to flow into the container 31. The container 31 can hold the electrolyte, which can then be analyzed within it. The piping assembly 20 can selectively connect the storage device 10 and the container 31. When connected, the electrolyte in the storage device 10 can be transported to the container 31 via the piping assembly 20, allowing it to be contained within the container 31 for subsequent electrolyte analysis. When it is not necessary to supply electrolyte to the container 31, the piping assembly 20 is disconnected, and the storage device 10 and container 31 are no longer connected. The container 31 is also connected to a drain port 331, through which the electrolyte in the container 31 can be discharged from the laser component analyzer 30.

[0040] The heat exchanger 32 has both cooling and heating functions. It can be located below the container 31 and can exchange heat with it. When cooling, the heat exchanger 32 can convert the liquid electrolyte in the container 31 into a solid state. When heating, the heat exchanger 32 can convert the solid electrolyte in the container 31 into a liquid state. The heat exchanger 32 enables the conversion between solid and liquid states of the electrolyte. During electrolyte composition detection, the heat exchanger 32 converts the liquid electrolyte into a solid state, and the laser composition analyzer 30 emits a laser beam into the solid electrolyte to obtain spectral data. Based on this spectral data, the composition of the electrolyte is determined, which facilitates highly sensitive quantitative detection of electrolyte components, improves detection stability, and enhances detection accuracy.

[0041] As an example, the heat exchanger 32 may include a heat exchange tube, through which a high-temperature medium or a low-temperature medium can be introduced, thereby realizing the heating and cooling functions of the heat exchanger 32. When the heat exchanger 32 needs to heat, a high-temperature medium is introduced into the heat exchange tube, which can exchange heat with the container 31, and the heat exchanger 32 can convert the solid electrolyte in the container 31 into a liquid state. When the heat exchanger 32 needs to cool, a low-temperature medium is introduced into the heat exchange tube, which can exchange heat with the container 31, and the heat exchanger 32 can convert the liquid electrolyte in the container 31 into a solid state.

[0042] In some embodiments of this utility model, the heat exchanger 32 is configured as a thermoelectric cooler.

[0043] The thermoelectric cooler is connected to a power source. By changing the direction of current flow within the thermoelectric cooler, the cooling and heating functions of the heat exchange element 32 can be switched. As an example, the thermoelectric cooler can be used in conjunction with a container 31 for heat exchange, and the thermoelectric cooler can convert the liquid electrolyte within the container 31 into a solid state.

[0044] In some embodiments of this utility model, such as Figure 2 As shown, the laser component analysis device 30 may include: a drain pipe 33, which is connected to the container 31 and defines a drain channel. The drain channel is configured as a drain port 331. The drain pipe 33 is provided with a drain valve 332, which is used to open or close the drain port 331.

[0045] The drain pipe 33 can be connected to the container 31, defining a drain channel, which can be configured as a drain port 331. Liquid in the container 31 can be drained through the drain channel. Liquid in the container 31 can be discharged from the laser component analyzer 30 through the drain port 331. The drain pipe 33 is equipped with a drain valve 332, which can selectively open or close, thereby selectively opening or blocking the drain pipe 33. The drain valve 332 can be a solenoid valve. When liquid in the container 31 needs to be drained, the drain valve 332 opens, the drain pipe 33 is open, and the drain port 331 opens, allowing liquid to drain through the drain port 331. When liquid in the container 31 does not need to be drained, the drain valve 332 closes, the drain pipe 33 is blocked, and the drain port 331 closes.

[0046] In some embodiments of this utility model, such as Figure 2 As shown, the electrolyte composition detection system 1 may further include: an overflow device 40, which is connected to the container 31.

[0047] The overflow device 40 can be connected to the container 31. As an example, the overflow device 40 can be connected in parallel with the drain pipe 33. As another example, the overflow device 40 can be connected to the container 31 through the drain pipe 33. The liquid in the container 31 can be discharged through the overflow device 40. By setting the overflow device 40, it is possible to prevent the liquid in the container 31 from becoming too large and overflowing into the interior of the laser component analysis device 30. Furthermore, when the liquid in the container 31 cannot be discharged through the drain pipe 33, the liquid in the container 31 can flow into the overflow device 40.

[0048] As an example, when liquid is added to the container 31, if there is too much liquid in the container 31, the liquid can flow to the overflow device 40, thereby preventing the liquid in the container 31 from overflowing into the laser component analysis device 30, which helps improve the safety of the laser component analysis device 30 during operation. As another example, when the liquid in the container 31 needs to be drained, if the drain valve 332 does not open in time, the liquid can flow into the overflow device 40, thereby preventing the liquid in the container 31 from flowing back into the pipeline assembly 20, which also helps improve the safety of the laser component analysis device 30 during operation.

[0049] In some embodiments of this utility model, the overflow device 40 is configured as an overflow pipe 41, the container 31 has a container outlet 311, the overflow pipe 41 is connected to the container outlet 311, and the outlet of the overflow pipe 41 is set at a height lower than the height of the container 31.

[0050] The overflow device 40 can be configured as an overflow pipe 41. As an example, the overflow pipe 41 can be directly connected to the container outlet 311. As another example, the overflow pipe 41 can be connected to the container outlet 311 through a drain pipe 33. This application describes the example of the overflow pipe 41 being connected to the container outlet 311 through a drain pipe 33. The liquid in the container 31 can be discharged through the container outlet 311 to the drain pipe 33, and the liquid in the drain pipe 33 can flow into the overflow pipe 41. The overflow pipe 41 is connected to the container 31, and the outlet height of the overflow pipe 41 is lower than the height of the container 31. When the liquid level in the container 31 is higher than the outlet height of the overflow pipe 41, the liquid in the container 31 can flow to the overflow pipe 41, so that the liquid level in the container 31 will never be higher than the height of the container 31, and the liquid in the container 31 will not overflow.

[0051] The liquid in the container 31 can flow from the container outlet 311 to the drain pipe 33. The liquid in the container 31 can enter the overflow pipe 41 through the drain pipe 33, which prevents the liquid in the container 31 from overflowing into the laser component analysis device 30. When the container 31 needs to be drained, if the drain valve 332 is closed, the liquid cannot flow out through the drain pipe 33. The liquid can be drained through the overflow pipe 41, which prevents the liquid in the container 31 from flowing back and helps to ensure the safety of the laser component analysis device 30.

[0052] In some embodiments of this utility model, such as Figure 2As shown, the laser component analysis device 30 may further include: a spectral acquisition module 34 and a determination module connected in communication. The container 31 has an open opening. The spectral acquisition module 34 is set corresponding to the open opening. The spectral acquisition module 34 emits laser light through the open opening to the solid electrolyte in the container 31 to obtain the spectral data information of the electrolyte. The determination module determines the composition of the electrolyte based on the spectral data information.

[0053] When the laser component analysis device 30 is placed on the ground or on an operating table, it can be positioned vertically. The container 31 has an open opening, which can face upwards. The spectral acquisition module 34 can be positioned corresponding to the open opening. The spectral acquisition module 34 and the container 31 can be arranged sequentially along the height of the laser component analysis device 30. Figure 1 When setting the orientation, the height orientation of the laser component analysis device 30 is as follows: Figure 1 The Z-axis is located above the open opening. The spectral acquisition module 34 can emit a laser, which can be directed through the open opening towards the solid electrolyte in the container 31. The solid electrolyte is burned, and the spectral acquisition module 34 can acquire the spectral data information of the electrolyte. As an example, the spectral acquisition module 34 may include a laser, a laser focusing lens, and a spectrometer. The laser, laser focusing lens, and open opening can be arranged sequentially along the height direction of the laser component analysis device 30. The laser can emit a laser, and the laser focusing lens can focus the laser onto the solid electrolyte, thereby burning the solid electrolyte and generating plasma. The light signal emitted by the plasma can be transmitted to the spectrometer, which obtains the spectral signal containing the elemental composition information of the electrolyte, thus completing the acquisition of spectral data information.

[0054] The spectral acquisition module 34 and the determination module can communicate with each other. The spectral acquisition module 34 can transmit the acquired spectral data to the determination module, which can then determine the composition of the electrolyte based on the spectral data. For example, the determination module can be configured as a computer. The determination module can process and analyze the spectral data to perform quantitative analysis of the elements contained in the electrolyte. By setting up the spectral acquisition module 34 and the determination module, the composition of the electrolyte can be automatically and in real time detected, which is of great significance for the construction of smart factories.

[0055] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the pipeline assembly 20 may include: a first pipeline assembly 21 and a second pipeline assembly 22, the first pipeline assembly 21 and the second pipeline assembly 22 are connected, the first pipeline assembly 21 is connected to the liquid storage device 10, the second pipeline assembly 22 is located inside the laser component analysis device 30, and the second pipeline assembly 22 is connected to the container 31.

[0056] The first pipeline assembly 21 can be located outside the laser component analysis device 30. The first pipeline assembly 21 can be connected to the liquid storage device 10 and the second pipeline assembly 22. The second pipeline assembly 22 can be located inside the laser component analysis device 30. The first pipeline assembly 21 and the second pipeline assembly 22 can be connected in series. The second pipeline assembly 22 can connect the first pipeline assembly 21 and the container 31. The electrolyte in the liquid storage device 10 can flow to the container 31 through the first pipeline assembly 21 and the second pipeline assembly 22. The electrolyte can be converted into a solid state in the container 31. The spectral acquisition module 34 can emit laser light to the solid electrolyte in the container 31 to obtain the spectral data information of the electrolyte. The determination module determines the composition of the electrolyte based on the spectral data information, thereby realizing the effect of directly detecting and analyzing the electrolyte composition in the electrolyte composition detection system 1, which is beneficial to improving the efficiency of electrolyte composition detection.

[0057] In some embodiments of this utility model, such as Figure 1 As shown, the first pipeline assembly 21 may include: a first main pipeline 211 and multiple branch pipelines 212. The first main pipeline 211 is connected to the second pipeline assembly 22 and the multiple branch pipelines 212. The multiple branch pipelines 212 are respectively connected to different liquid storage devices 10. Each branch pipeline 212 is equipped with a drive pump 2121.

[0058] The first main pipeline 211 can be connected to the second pipeline assembly 22. Multiple branch pipelines 212 are all connected to the first main pipeline 211, and each branch pipeline 212 can be connected to the second pipeline assembly 22 via the first main pipeline 211. There can be multiple storage devices 10, which can be used to store different types of electrolytes. Multiple branch pipelines 212 can be connected to different storage devices 10, and each storage device 10 has a corresponding branch pipeline 212. The electrolyte in the storage device 10 can flow into the first main pipeline 211 through the corresponding branch pipeline 212, and the electrolyte can flow into the container 31 through the first main pipeline 211 and the second pipeline assembly 22. Each branch pipe 212 is equipped with a drive pump 2121. Each drive pump 2121 can pump the electrolyte in the corresponding storage device 10 into the corresponding branch pipe 212. During the process of delivering electrolyte to the container 31, the drive pump 2121 works continuously, thereby ensuring the continuous flow of electrolyte in the first pipe assembly 21, so that the container 31 can hold enough electrolyte, which is beneficial to ensuring the accuracy and reliability of the test. It should be noted that the drive pump 2121 can be a peristaltic pump, a syringe pump, etc. In this embodiment, a peristaltic pump is used as an example for illustration.

[0059] In some embodiments of this utility model, such as Figure 1 As shown, each branch pipe 212 is equipped with a first on / off valve 2122.

[0060] There can be multiple first on-off valves 2122, each corresponding to one of multiple branch pipes 212. Each branch pipe 212 is equipped with a first on-off valve 2122, which can be a solenoid valve. The first on-off valve 2122 can selectively open or close, thereby controlling the flow or blockage of the corresponding branch pipe 212. When the first on-off valve 2122 is open, the corresponding branch pipe 212 is open, allowing the electrolyte in the corresponding liquid storage device 10 to flow into the first main pipe 211. When the first on-off valve 2122 is closed, the corresponding branch pipe 212 is blocked, preventing the electrolyte in the corresponding liquid storage device 10 from flowing into the first main pipe 211. By selectively opening or closing the first on-off valve 2122, the ability to control whether the electrolyte in the corresponding liquid storage device 10 can enter the first main pipe 211 can be achieved.

[0061] When multiple liquid storage devices 10 are connected in series, multiple first on / off valves 2122 can be opened simultaneously, allowing the electrolyte in multiple liquid storage devices 10 to flow into the first main pipeline 211. Multiple electrolytes can mix within the first main pipeline 211 and simultaneously flow into the container 31. The laser component analysis device 30 can determine the composition of the mixed electrolyte, thus achieving the effect of simultaneous detection of multiple electrolytes. When multiple liquid storage devices 10 are connected in parallel, multiple first on / off valves 2122 can be opened separately, enabling the separate control of different electrolytes entering the laser component analysis device 30. This allows for the separate detection of different types of electrolyte components and multi-point sampling, improving the versatility of the electrolyte component detection system 1.

[0062] In some embodiments of the present invention, the first main pipeline 211 is provided with a filter device 2123; and / or each branch pipeline 212 is provided with a filter device 2123.

[0063] The first main pipeline 211 may be equipped with a filter device 2123, or each branch pipeline 212 may be equipped with a filter device 2123, or both the first main pipeline 211 and each branch pipeline 212 may be equipped with a filter device 2123. This application uses the example of each branch pipeline 212 being equipped with a filter device 2123 for illustration. The filter device 2123 can be used to filter impurities in the electrolyte, improve the cleanliness of the electrolyte, and help improve the reliability of the electrolyte component detection system 1 in detecting the electrolyte components. The filter device 2123 requires regular maintenance to ensure its reliability.

[0064] In some embodiments of this utility model, such as Figure 1 As shown, the first main pipeline 211 is equipped with a first liquid flow detector 2111.

[0065] The first liquid flow detector 2111 can be used to detect the presence of electrolyte in the first main pipeline 211. The first liquid flow detector 2111 can be constructed as a capacitive sensor, a fluorescence detector, etc. This embodiment uses a capacitive sensor as an example for explanation. The first liquid flow detector 2111 can be communicatively connected to the controller 90. When electrolyte passes through the first liquid flow detector 2111, it can send a signal to the controller 90. The controller 90 can determine from the signal from the first liquid flow detector 2111 that the electrolyte is flowing normally in the first main pipeline 211, thus allowing subsequent detection operations to continue.

[0066] In some embodiments of this utility model, multiple branch pipes 212 are connected in parallel or in series.

[0067] Multiple branch pipes 212 can be connected in series and interconnected. The electrolytes in multiple storage devices 10 can be mixed and then enter the laser component analysis device 30. The laser component analysis device 30 can determine the composition of the mixed electrolyte, thereby achieving the effect of simultaneous detection of multiple groups of electrolytes. Multiple branch pipes 212 can also be connected in parallel. By controlling the opening of the first on / off valve 2122 of one of the branch pipes 212, the electrolyte in the corresponding storage device 10 can be individually delivered into the laser component analysis device 30. The electrolytes in multiple storage devices 10 can enter the laser component analysis device 30 separately, and their composition can be determined within the laser component analysis device 30, thereby achieving the effect of multi-point sampling.

[0068] In some embodiments of this utility model, such as Figure 2 As shown, the second piping assembly 22 may include: a buffer tank 221, a second main pipeline 222 and a third main pipeline 223. The second main pipeline 222 connects the buffer tank 221 and the first piping assembly 21, and the third main pipeline 223 connects the buffer tank 221 and the container 31.

[0069] The second main pipeline 222 can be connected to the buffer tank 221, and the second main pipeline 222 can be connected to the first pipeline assembly 21, thus connecting the buffer tank 221 and the first pipeline assembly 21. The third main pipeline 223 can be connected to the buffer tank 221, and the third main pipeline 223 can be connected to the holding container 31, thus connecting the buffer tank 221 and the holding container 31. The first pipeline assembly 21, the second main pipeline 222, the buffer tank 221, the third main pipeline 223, and the holding container 31 are connected sequentially along the direction of liquid flow. The electrolyte can flow to the buffer tank 221 through the first pipeline assembly 21 and the second main pipeline 222. The buffer tank 221 can buffer the electrolyte and stabilize the electrolyte flow rate and liquid level. After the electrolyte flows out of the buffer tank 221, it can flow through the third main pipeline 223 to the container 31. The electrolyte can be converted into a solid in the container 31. The solid electrolyte is burned in the container 31, thereby completing the detection of the electrolyte composition.

[0070] In some embodiments of this utility model, such as Figure 2 As shown, the second main pipeline 222 is equipped with a second on / off valve 2221.

[0071] The second main pipeline 222 is equipped with a second on / off valve 2221, which can be a solenoid valve. The second on / off valve 2221 can selectively open or close, thereby controlling the flow or blockage of the second main pipeline 222. When the second on / off valve 2221 is open, the second main pipeline 222 is open, allowing liquid in the first pipeline assembly 21 to flow into the second main pipeline 222. When the second on / off valve 2221 is closed, the second main pipeline 222 is blocked, preventing liquid in the first pipeline assembly 21 from flowing into the second main pipeline 222. By opening or closing the second on / off valve 2221, the system can control whether liquid in the first pipeline assembly 21 can enter the second main pipeline 222, thus enabling the electrolyte component detection system 1 to complete different test steps. For example, when it is necessary to inject electrolyte into the container 31, the second on / off valve 2221 is opened. When the spectral acquisition module 34 emits a laser to the solid electrolyte in the container 31 to obtain the spectral data information of the electrolyte, there is no need to input liquid electrolyte into the container 31, and the second on / off valve 2221 closes.

[0072] In some embodiments of this utility model, such as Figure 2 As shown, the third main pipeline 223 is equipped with a second liquid flow detector 2231.

[0073] The second liquid flow detector 2231 can be used to detect whether electrolyte flows in the third main pipeline 223. The second liquid flow detector 2231 can be constructed as a capacitive sensor, a fluorescence detector, etc. In this embodiment, the second liquid flow detector 2231 is constructed as a capacitive sensor as an example. The second liquid flow detector 2231 can be communicatively connected to the controller 90. When the electrolyte passes through the second liquid flow detector 2231, the second liquid flow detector 2231 can send a signal to the controller 90. The controller 90 can determine that the electrolyte is flowing in the third main pipeline 223 based on the signal from the second liquid flow detector 2231. The electrolyte is flowing in the third main pipeline 223, which is connected to the container 31. The electrolyte can flow to the container 31, so that subsequent detection operations can continue.

[0074] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the electrolyte composition detection system 1 may further include: a first flushing pipeline 50, and the second pipeline assembly 22 may further include a fourth main pipeline 224, which is connected between the buffer tank 221 and the first flushing pipeline 50. At least one of the first flushing pipeline 50 and the fourth main pipeline 224 is provided with a third on / off valve 70.

[0075] The first flushing pipe 50 can be connected to the fourth main pipe 224, which can be connected to the buffer tank 221. The fourth main pipe 224 can connect the buffer tank 221 and the first flushing pipe 50. When the electrolyte component detection system 1 needs to be flushed, flushing water can enter the electrolyte component detection system 1 through the first flushing pipe 50. The flushing water can flow to the buffer tank 221 through the first flushing pipe 50 and the fourth main pipe 224. The flushing water can flow to the holding container 31 through the third main pipe 223. The flushing water can flush the buffer tank 221 and the holding container 31, and can carry away the electrolyte stored in the buffer tank 221 and the holding container 31. The flushing water can be discharged from the laser component analysis device 30 through the drain pipe 33, thereby achieving the effect of flushing the second pipe assembly 22.

[0076] The first flushing pipeline 50 may be equipped with a third on / off valve 70, or the fourth main pipeline 224 may be equipped with a third on / off valve 70, or both the first flushing pipeline 50 and the fourth main pipeline 224 may be equipped with a third on / off valve 70. This embodiment of the application uses the example of both the first flushing pipeline 50 and the fourth main pipeline 224 being equipped with a third on / off valve 70 for illustration. The third on / off valve 70 can be a solenoid valve. The third on / off valve 70 on the first flushing pipeline 50 and the third on / off valve 70 on the fourth main pipeline 224 can open synchronously. When both the third on / off valves 70 on the first flushing pipeline 50 and the fourth main pipeline 224 are open, both the first flushing pipeline 50 and the fourth main pipeline 224 are connected, and flushing water can enter the laser component analysis device 30 through the first flushing pipeline 50 and the fourth main pipeline 224, flushing the second pipeline assembly 22. When flushing the second pipeline assembly 22 is no longer needed, the third on / off valve 70 on the first flushing pipeline 50 can be closed first. When the third on / off valve 70 of the first flushing pipeline 50 is closed, the first flushing pipeline 50 is blocked, and flushing water cannot enter the fourth main pipeline 224 through the first flushing pipeline 50. When no more flushing water flows through the second liquid flow detector 2231, the third on / off valve 70 on the fourth main pipeline 224 is closed, thereby achieving the effect of draining the flushing water as much as possible.

[0077] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the electrolyte composition detection system 1 may further include: a second flushing pipeline 60, which is connected to the first pipeline assembly 21 and is provided with a fourth on / off valve 61.

[0078] The second flushing pipe 60 can be connected to the first pipe assembly 21. When the electrolyte component detection system 1 needs flushing, flushing water can enter the electrolyte component detection system 1 through the second flushing pipe 60. The flushing water can flush the first pipe assembly 21 and remove the electrolyte inside the first pipe assembly 21, preparing it for subsequent detection of other types of electrolytes. The first pipe assembly 21 can be connected to the second main pipe 222. The flushing water in the first pipe assembly 21 can flow into the laser component analysis device 30 through the second main pipe 222, and then be discharged through the drain port 331 of the laser component analysis device 30.

[0079] The second flushing pipe 60 may be equipped with a fourth on / off valve 61, which may be a solenoid valve. The fourth on / off valve 61 can selectively open or close. When the fourth on / off valve 61 is open, the second flushing pipe 60 is open, and flushing water can enter the first pipe assembly 21. When the fourth on / off valve 61 is closed, the second flushing pipe 60 is blocked, and flushing water cannot enter the first pipe assembly 21. By setting up the first flushing pipe 50 and the second flushing pipe 60, flushing water can flush the first pipe assembly 21 and the second pipe assembly 22, thereby discharging the residual electrolyte in the pipe assembly 20 into the electrolyte component detection system 1.

[0080] In some embodiments of this utility model, such as Figure 1 As shown, the electrolyte composition detection system 1 may further include: a waste discharge pipe 80, which is connected to the liquid discharge port 331.

[0081] Both the rinsing water and the electrolyte can be discharged from the laser component analysis device 30 through the drain port 331. The waste discharge pipe 80 is connected to the drain port 331, and the rinsing water and electrolyte can be discharged from the electrolyte component detection system 1 through the waste discharge pipe 80, thereby achieving the effect of discharging the waste liquid from the electrolyte component detection system 1.

[0082] In some embodiments of this utility model, the electrolyte component detection system 1 may include a controller 90. The controller 90 may be communicatively connected to the first liquid flow detector 2111, the drive pump 2121, the first on / off valve 2122, the second on / off valve 2221, the second liquid flow detector 2231, the heat exchanger 32, the drain valve 332, the spectral acquisition module 34, the determination module, the fourth on / off valve 61, and the third on / off valve 70. The controller 90 may control the operation of each component of the electrolyte component detection system 1.

[0083] The electrolyte component detection system 1 can also communicate with the intelligent control cabinet in the central control room. Both the controller 90 and the intelligent control cabinet can control the laser component analysis device 30. The test personnel can control the laser component analysis device 30 on-site through the controller 90, and the test personnel can remotely control the laser component analysis device 30 through the intelligent control cabinet.

[0084] In this embodiment, the online detection of electrolyte components may include four steps: rinsing, sampling, detection, and flushing. This embodiment uses multiple branch pipelines 212 connected in parallel as an example for illustration.

[0085] First, before testing the electrolyte composition, the pipeline assembly 20 and the laser component analysis device 30 are rinsed with the electrolyte to be tested. The first on / off valve 2122 on the branch pipeline 212 connected to the storage device 10 containing the electrolyte to be tested is opened, the second on / off valve 2221 is opened, and the drive pump 2121 is started to draw electrolyte from the corresponding storage device 10. The electrolyte flows through the corresponding branch pipeline 212 to the first main pipeline 211. The electrolyte flows through the filter device 2123 and the first liquid flow detector 2111. The first liquid flow detector 2111 sends a detection signal to the controller 90, and the controller 90 confirms that the electrolyte is flowing normally. The electrolyte flows to the second pipeline assembly 22, the drain valve 332 opens, and the electrolyte flows through the second main pipeline 222, buffer tank 221, third main pipeline 223, and container 31. When the electrolyte flows through the second liquid flow detector 2231, the second liquid flow detector 2231 sends a detection signal to the controller 90, and the controller 90 confirms that the electrolyte is flowing normally. The electrolyte enters the waste discharge pipeline 80 through the drain port 331, and the electrolyte is discharged from the electrolyte composition detection system 1. Before sampling, the pipeline assembly 20 and the laser component analysis device 30 are rinsed with the electrolyte to be tested. This can reduce the influence of residual rinsing water in the electrolyte component detection system 1 on the detection results. After rinsing, the drive pump 2121 is turned off and the first on / off valve 2122 is closed. When the second liquid flow detector 2231 detects that no more electrolyte is flowing through it, the second on / off valve 2221 is closed. When no more liquid flows out of the waste discharge pipeline 80, the drain valve 332 is closed.

[0086] Secondly, before detecting the electrolyte composition, the electrolyte to be tested is transported into the container 31. The first on / off valve 2122 on the branch pipe 212 connected to the storage device 10 containing the electrolyte to be tested is opened, and the second on / off valve 2221 is opened. The drive pump 2121 is started to draw electrolyte from the corresponding storage device 10. The electrolyte flows through the first pipeline assembly 21 to the laser component analysis device 30. The electrolyte flows through the filter device 2123, the first liquid flow detector 2111, and the second liquid flow detector 2231. The first liquid flow detector 2111 and the second liquid flow detector 2231 transmit detection signals to the controller 90, and the controller 90 confirms that the electrolyte is flowing normally. After the second liquid flow detector 2231 sends a detection signal to the controller 90, the electrolyte can flow into the container 31, where it is stored.

[0087] Then, the electrolyte composition is detected. After the second liquid flow detector 2231 sends a detection signal to the controller 90, the drive pump 2121, the first on / off valve 2122, and the second on / off valve 2221 are shut down. The heat exchanger 32 is energized, and it converts the liquid electrolyte in the container 31 into a solid state. The spectral acquisition module 34 and the determination module are then activated. The spectral acquisition module 34 emits laser light through its open port into the solid electrolyte in the container 31 to obtain spectral data information of the electrolyte. The determination module determines the composition of the electrolyte based on the spectral data information.

[0088] Finally, after completing the electrolyte composition detection, flush the pipeline assembly 20 and the laser composition analyzer 30 with flushing water. Reverse the power supply to the heat exchanger 32 to put it into heating mode. The heat exchanger 32 converts the solid electrolyte in the container 31 into a liquid state, and then de-energizes the heat exchanger 32. Open the second on / off valve 2221, the third on / off valve 70 and the fourth on / off valve 61 on the first flushing pipeline 50 and the fourth main pipeline 224, as well as the drain valve 332. Flushing water can enter the first pipeline assembly 21 through the second flushing pipeline 60 to clean the first pipeline assembly 21. The used flushing water can then enter the second pipeline assembly 22 through the second main pipeline 222. Flushing water can also enter the fourth main pipeline 224 through the first flushing pipeline 50 to clean the second pipeline assembly 22. The flushing water entering the electrolyte composition detection system 1 through the first flushing pipe 50 and the flushing water entering the electrolyte composition detection system 1 through the second flushing pipe 60 converge in the buffer tank 221. The flushing water enters the holding container 31 through the third main pipe 223. The flushing water can carry away the liquid electrolyte in the holding container 31 and cleans the holding container 31. The flushing water is discharged from the laser composition analysis device 30 through the drain port 331 and discharged from the electrolyte composition detection system 1 through the waste discharge pipe 80. First, close the third on / off valve 70 and the fourth on / off valve 61 on the first flushing pipe 50. When the second liquid flow detector 2231 detects that no more flushing water is flowing through the second liquid flow detector 2231, close the second on / off valve 2221 and the third on / off valve 70 on the fourth main pipe 224. When no more liquid flows out of the waste discharge pipe 80, close the drain valve 332.
