[0028] Reference below Figure 1-Figure 2 An electrolyte component detection system 1 according to an embodiment of the present invention is described.

[0029] According to the electrolyte composition detection system 1 of the embodiment of the present invention, Figure 1 and Figure 2As shown, the electrolyte composition detection system 1 may include: a liquid storage device 10, a pipeline assembly 20 and a laser composition analysis device 30, the liquid storage device 10 is used to store electrolyte, the pipeline assembly 20 is connected to both the liquid storage device 10 and the laser composition analysis device 30, the pipeline assembly 20 is used to transport the electrolyte in the liquid storage device 10 to the laser composition analysis device 30, the laser composition analysis device 30 is used to convert the electrolyte into a solid state, and the laser composition analysis device 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.

[0030] It should be noted that in the relevant technologies, the composition of the electrolyte is currently mainly determined by the method of manual sampling followed by laboratory testing, which has the disadvantages of complex process, poor real-time performance, poor representativeness, and low detection frequency. In addition, the use of technology for automatic real-time detection of electrolyte composition is of great significance to the construction of smart factories. The current technology for quantitative detection of electrolyte composition is mainly chemical titration, but a single device in the chemical titration method can only detect one element, which has high cost of use, cannot meet the needs of simultaneous detection of multiple components, and has low detection efficiency.

[0031] Based on this, the embodiment of the present application proposes an electrolyte component detection system 1, wherein the liquid storage device 10 may be a container such as an electrolyte storage tank or an elevated tank, and the liquid storage device 10 may be used to store electrolyte, and the liquid storage device 10 may provide electrolyte for the electrolyte component detection system 1, and the electrolyte in the liquid storage device 10 is a liquid electrolyte. The pipeline assembly 20 may be connected to the liquid storage device 10, and the pipeline assembly 20 may be connected to the laser component analysis device 30, and the pipeline assembly 20 communicates the liquid storage device 10 and the laser component analysis device 30, and the electrolyte in the liquid storage device 10 may be transported to the laser component analysis device 30 through the pipeline assembly 20. The laser component analysis device 30 may convert the liquid electrolyte into a solid state, and the laser component analysis device 30 may emit a laser to the solid electrolyte, and the laser burns the solid electrolyte to generate plasma, and the laser component analysis device 30 may obtain the light signal emitted by the plasma, so as to obtain the spectral data information of the electrolyte, and the composition of the electrolyte may be determined by analyzing the spectral data information.

[0032] As an example, there may be multiple liquid storage devices 10, and the multiple liquid storage devices 10 may be used to store different types of electrolytes. The multiple liquid storage devices 10 may be connected in series, and the electrolytes in the multiple liquid storage devices 10 connected in series may be applied to the same process. The electrolytes in the multiple liquid storage devices 10 connected in series may be mixed and enter the laser component analysis device 30 together. The laser component analysis device 30 may determine the composition of the mixed electrolyte, and achieve the effect of simultaneous detection of multiple groups of electrolytes. The multiple liquid storage devices 10 may be connected in parallel, and the electrolytes in the multiple liquid storage devices 10 connected in parallel may be electrolytes for multiple processes respectively. The electrolytes in the multiple liquid storage devices 10 connected in parallel may enter the laser component analysis device 30 respectively, and the laser component analysis device 30 may determine the composition of the electrolyte, and achieve the effect of multi-point sampling.

[0033] In the embodiment of the present application, by transporting the electrolyte in the liquid 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 obtain spectral data information of the electrolyte and determine the composition of the electrolyte based on the spectral data information, which can achieve the effect of automatic real-time detection of the electrolyte composition. The liquid storage device 10 can be multiple, which can achieve 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. By converting the electrolyte into a solid state, high-sensitivity quantitative detection of the electrolyte composition can be achieved, which is beneficial to improving the stability of the detection and improving the detection accuracy.

[0034] In some embodiments of the present invention, Figure 2 As shown, the laser component analysis device 30 has a drain port 331 , which is selectively opened or closed. The laser component analysis device 30 is also used to convert the solid electrolyte into a liquid electrolyte so as to discharge the liquid electrolyte out of the laser component analysis device 30 through the drain port 331 .

[0035] The laser component analyzer 30 has a drain port 331, through which the laser component analyzer 30 can drain. The drain port 331 can be selectively opened or closed. When the laser component analyzer 30 needs to drain, the drain port 331 is opened, and when the laser component analyzer 30 does not need to drain, the drain port 331 is closed. After completing the component detection of the electrolyte, the laser component analyzer 30 can convert the solid electrolyte into a liquid electrolyte, and the liquid electrolyte can be discharged from the laser component analyzer 30 through the drain port 331. By selectively opening or closing the drain port 331, the liquid in the laser component analyzer 30 can be selectively discharged, thereby meeting the draining requirements of the laser component analyzer 30.

[0036] As an example, before performing the electrolyte component detection, the electrolyte to be detected can be used to rinse the electrolyte component detection system 1, thereby reducing the probability that other liquids remaining in the electrolyte component detection system 1 affect the detection result, and the electrolyte used for rinsing can be discharged from the laser component analysis device 30 through the drain port 331. After performing the electrolyte component detection, the electrolyte component detection system 1 can be rinsed with rinse water, so that the electrolyte that has been detected can be discharged from the laser component analysis device 30, and the rinse water and the electrolyte that has been detected can be discharged from the laser component analysis device 30 through the drain port 331.

[0037] In some embodiments of the present invention, 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 the liquid storage device 10 and the container 31, the container 31 is connected to the drain port 331, and 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.

[0038] The pipeline assembly 20 can be connected to the container 31, and the electrolyte can flow into the container 31 through the pipeline assembly 20. The container 31 can be used to hold the electrolyte, and the electrolyte can be detected in the container 31. The pipeline assembly 20 can selectively connect the liquid storage device 10 and the container 31. When the liquid storage device 10 and the container 31 are connected, the electrolyte in the liquid storage device 10 can be transported to the container 31 through the pipeline assembly 20, so that the electrolyte can be contained in the container 31, thereby completing the subsequent detection of the electrolyte. When it is not necessary to transport the electrolyte to the container 31, the pipeline assembly 20 is disconnected, and the liquid storage device 10 and the container 31 are not connected. The container 31 is also connected to the drain port 331, and the electrolyte in the container 31 can be discharged from the laser component analysis device 30 through the drain port 331.

[0039] The heat exchanger 32 has the functions of cooling and heating. The heat exchanger 32 can be located below the container 31, and the heat exchanger 32 can cooperate with the container 31 for heat exchange. When the heat exchanger 32 is cooling, the heat exchanger 32 can cooperate with the container 31 for heat exchange, and the heat exchanger 32 can convert the liquid electrolyte in the container 31 into a solid state. When the heat exchanger 32 is heating, the heat exchanger 32 can cooperate with the container 31 for heat exchange, and the heat exchanger 32 can convert the solid electrolyte in the container 31 into a liquid state. The heat exchanger 32 can realize the conversion of the electrolyte between the solid state and the liquid state. When the component of the electrolyte is detected, the heat exchanger 32 converts the liquid electrolyte into a solid state. The laser component analysis device 30 emits a laser to the solid electrolyte to obtain the spectral data information of the electrolyte, and determines the components of the electrolyte according to the spectral data information, which is conducive to realizing highly sensitive quantitative detection of the components of the electrolyte, and is conducive to improving the stability of the detection and improving the detection accuracy.

[0040] As an example, the heat exchanger 32 can be constructed as a thermoelectric cooler, which is connected to a power source. By changing the flow direction of the current in the thermoelectric cooler, the conversion between the cooling function and the heating function of the heat exchanger 32 can be realized. As another example, the heat exchanger 32 can include a heat exchange tube, and a high-temperature medium or a low-temperature medium can be passed into the heat exchange tube, so as to realize the heating and cooling functions of the heat exchanger 32. When the heat exchanger 32 needs to heat, a high-temperature medium is passed into the heat exchange tube, and the high-temperature medium can cooperate with the container 31 for heat exchange, 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 passed into the heat exchange tube, and the low-temperature medium can cooperate with the container 31 for heat exchange, and the heat exchanger 32 can convert the liquid electrolyte in the container 31 into a solid state.

[0041] In some embodiments of the present invention, 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, and the drain pipe 33 is provided with a drain valve 332, which is used to open or close the drain port 331.

[0042] The drain pipe 33 may be connected to the container 31, and the drain pipe 33 may define a drain channel, and the drain channel may be configured as a drain port 331, and the liquid in the container 31 may be discharged through the drain channel. The liquid in the container 31 may be discharged from the laser component analysis device 30 through the drain port 331. The drain pipe 33 is provided with a drain valve 332, and the drain valve 332 may be selectively opened or closed, so that the drain pipe 33 is selectively connected or blocked, and the drain valve 332 may be a solenoid valve. When the liquid in the container 31 needs to be discharged, the drain valve 332 is opened, the drain pipe 33 is connected, the drain port 331 is opened, and the liquid may be discharged through the drain port 331. When the liquid in the container 31 does not need to be discharged, the drain valve 332 is closed, the drain pipe 33 is blocked, and the drain port 331 is closed.

[0043] In some embodiments of the present invention, Figure 2 As shown, the electrolyte composition detection system 1 may further include: an overflow device 40 , which is connected to the container 31 .

[0044] The overflow device 40 may be in communication with the container 31. As an example, the overflow device 40 may be connected in parallel with the drain pipe 33. As another example, the overflow device 40 may be in communication with the container 31 through the drain pipe 33. The liquid in the container 31 may be discharged through the overflow device 40. By providing the overflow device 40, it is possible to avoid excessive liquid in the container 31, which may cause the liquid to overflow into the laser component analysis device 30. When the liquid in the container 31 cannot be discharged through the drain pipe 33, the liquid in the container 31 may flow into the overflow device 40.

[0045] As an example, when liquid is input into the container 31, if there is too much liquid in the container 31, the liquid in the container 31 can flow to the overflow device 40, thereby preventing the liquid in the container 31 from overflowing into the laser component analyzer 30, which is beneficial to improving the safety of the laser component analyzer 30. As another example, when the liquid in the container 31 needs to be discharged, if the drain valve 332 is not opened in time at this time, the liquid can flow into the overflow device 40, thereby preventing the liquid in the container 31 from flowing back to the pipeline assembly 20, which is beneficial to improving the safety of the laser component analyzer 30.

[0046] In some embodiments of the present invention, the overflow device 40 is constructed 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.

[0047] 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 the drain pipe 33. The present application takes the overflow pipe 41 being connected to the container outlet 311 through the drain pipe 33 as an example for explanation. The liquid in the container 31 can be discharged to the drain pipe 33 through the container outlet 311, 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 setting height of the overflow pipe 41 is lower than the height of the container 31. When the liquid level of the liquid in the container 31 is higher than the outlet setting 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 the container 31.

[0048] The liquid in the container 31 can flow from the container outlet 311 to the drain pipe 33, and the liquid in the container 31 can enter the overflow pipe 41 through the drain pipe 33, so as to prevent the liquid in the container 31 from overflowing into the interior of the laser component analysis device 30. When the container 31 needs to be discharged, if the drain valve 332 is closed, the liquid cannot flow out through the drain pipe 33, and the liquid can be discharged through the overflow pipe 41, so as to prevent the liquid in the container 31 from flowing back, which is beneficial to ensure the safety of the laser component analysis device 30.

[0049] In some embodiments of the present invention, Figure 2 As shown, the laser component analysis device 30 may also include: a spectral acquisition module 34 and a determination module that are communicatively connected, the container 31 is formed with an open mouth, the spectral acquisition module 34 is arranged corresponding to the open mouth, the spectral acquisition module 34 emits a laser to the solid electrolyte in the container 31 through the open mouth to obtain spectral data information of the electrolyte, and the determination module determines the composition of the electrolyte according to the spectral data information.

[0050] When the laser component analysis device 30 is placed on the ground or on the operating table, the laser component analysis device 30 can be placed in the up-down direction. The container 31 is formed with an open mouth, and the open mouth of the container 31 can be opened toward the upper end of the container 31. The spectrum acquisition module 34 can be arranged corresponding to the open mouth. The spectrum acquisition module 34 can be arranged in sequence with the container 31 along the height direction of the laser component analysis device 30. When the laser component analysis device 30 is as shown in FIG. Figure 1 When the direction is set, the height direction of the laser component analysis device 30 is Figure 1The Z direction in the spectrum acquisition module 34 can be located above the open mouth, and the spectrum acquisition module 34 can emit a laser, and the laser can be emitted through the open mouth to the solid electrolyte in the container 31, and the solid electrolyte is burned, and the spectrum acquisition module 34 can obtain the spectrum data information of the electrolyte. As an example, the spectrum acquisition module 34 may include a laser, a laser focusing lens, and a spectrometer. The laser, the laser focusing lens, and the open mouth can be arranged in sequence 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 on the solid electrolyte, so that the solid electrolyte is burned and plasma is generated. The light signal emitted by the plasma can be transmitted to the spectrometer, and the spectrometer obtains a spectrum signal containing the elemental composition information of the electrolyte, and completes the collection of spectrum data information.

[0051] The spectrum acquisition module 34 and the determination module can be connected in communication. The spectrum acquisition module 34 can transmit the collected spectrum data information to the determination module. The determination module can determine the composition of the electrolyte according to the spectrum data information. As an example, the determination module can be constructed as a computer. The determination module can process and analyze the spectrum data information to complete the quantitative analysis of the elements contained in the electrolyte. By setting the spectrum acquisition module 34 and the determination module, the composition of the electrolyte can be automatically detected in real time, which is of great significance to the construction of smart factories.

The filter device 2123 requires regular maintenance to ensure the reliability of the filter device 2123.

[0061] In some embodiments of the present invention, Figure 1 As shown, the first main line 211 is provided with a first liquid flow detector 2111 .

[0062] The first liquid flow detector 2111 can be used to detect whether there is electrolyte in the first main circuit 211. The first liquid flow detector 2111 can be constructed as a capacitive sensor, a fluorescence detector, etc. The embodiment of the present application is described by taking the first liquid flow detector 2111 as a capacitive sensor as an example. The first liquid flow detector 2111 can be connected to the controller 90 for communication. When the electrolyte passes through the first liquid flow detector 2111, the first liquid flow detector 2111 can send a signal to the controller 90. The controller 90 can determine that the electrolyte flows in the first main circuit 211 according to the signal of the first liquid flow detector 2111. The electrolyte flows normally in the first main circuit 211, so that subsequent detection operations can continue.

[0063] In some embodiments of the present invention, a plurality of branch pipelines 212 are connected in parallel or in series.

[0064] Multiple branch pipelines 212 can be connected in series, and multiple branch pipelines 212 are interconnected.

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 pipelines 212 can be connected in parallel. By controlling the first on-off valve 2122 of one of the branch pipelines 212 to open, the effect of separately transporting the electrolyte in the corresponding liquid storage device 10 into the laser component analysis device 30 can be achieved. The electrolytes in multiple liquid storage devices 10 can enter the laser component analysis device 30 respectively, and their components can be determined in the laser component analysis device 30, thereby achieving the effect of multi-point sampling.

After the electrolyte flows out of the buffer tank 221, the electrolyte can flow to the container 31 through the third main line 223, and the electrolyte can be converted into a solid state in the container 31. The solid electrolyte is burned in the container 31, thereby completing the detection of the electrolyte composition.

[0068] The second main pipeline 222 is provided with a second opening and closing valve 2221, which can be a solenoid valve. The second opening and closing valve 2221 can be selectively opened or closed, so as to control the conduction or blockage of the second main pipeline 222. When the second opening and closing valve 2221 is opened, the second main pipeline 222 is conducted, and the liquid in the first pipeline assembly 21 can flow into the second main pipeline 222. When the second opening and closing valve 2221 is closed, the second main pipeline 222 is blocked, and the liquid in the first pipeline assembly 21 cannot flow into the second main pipeline 222. By opening or closing the second opening and closing valve 2221, the effect of controlling whether the liquid in the first pipeline assembly 21 can enter the second main pipeline 222 can be achieved, so that the electrolyte composition detection system 1 can complete different test steps. For example: when it is necessary to inject electrolyte into the container 31, the second opening and closing valve 2221 is opened. When the spectrum acquisition module 34 emits laser to the solid electrolyte in the container 31 to obtain spectrum data information of the electrolyte, there is no need to input liquid electrolyte into the container 31, and the second on-off valve 2221 is closed.

[0069] In some embodiments of the present invention, Figure 2 As shown, the third main line 223 is provided with a second liquid flow detector 2231 .

[0070] The second liquid flow detector 2231 can be used to detect whether there is electrolyte flowing in the third main circuit 223. The second liquid flow detector 2231 can be constructed as a capacitive sensor, a fluorescence detector, etc. The embodiment of the present application is described by taking the second liquid flow detector 2231 as a capacitive sensor as an example. The second liquid flow detector 2231 can be connected to the controller 90 for communication. 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 flows in the third main circuit 223 according to the signal of the second liquid flow detector 2231. The electrolyte flows in the third main circuit 223, and the third main circuit 223 is connected to the container 31. The electrolyte can flow to the container 31, so that the subsequent detection operation can continue.

[0071] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the electrolyte composition detection system 1 can also include: a first flushing pipeline 50, the second pipeline assembly 22 also includes a fourth main pipeline 224, the fourth main pipeline 224 is connected between the buffer tank 221 and the first flushing pipeline 50, and at least one of the first flushing pipeline 50 and the fourth main pipeline 224 is provided with a third opening and closing valve 70.

[0072] The first flushing pipeline 50 can be connected to the fourth main pipeline 224, the fourth main pipeline 224 can be connected to the buffer tank 221, and the fourth main pipeline 224 can communicate the buffer tank 221 and the first flushing pipeline 50. When the electrolyte component detection system 1 needs to be flushed, the flushing water can enter the electrolyte component detection system 1 through the first flushing pipeline 50, the flushing water can flow to the buffer tank 221 through the first flushing pipeline 50 and the fourth main pipeline 224, and the flushing water flows to the container 31 through the third main pipeline 223. The flushing water can flush the buffer tank 221 and the container 31, and the flushing water can take away the electrolyte in the buffer tank 221 and the container 31. The flushing water can be discharged from the laser component analysis device 30 from the drain pipe 33, thereby achieving the effect of flushing the second pipeline assembly 22 with the flushing water.

[0073] The first flushing pipeline 50 may be provided with a third opening and closing valve 70, or the fourth main pipeline 224 may be provided with a third opening and closing valve 70, or the first flushing pipeline 50 and the fourth main pipeline 224 may both be provided with a third opening and closing valve 70. The embodiment of the present application is described by taking the first flushing pipeline 50 and the fourth main pipeline 224 as an example in which the third opening and closing valve 70 is provided. The third opening and closing valve 70 may be a solenoid valve. The third opening and closing valve 70 on the first flushing pipeline 50 and the third opening and closing valve 70 on the fourth main pipeline 224 may be opened synchronously. When the third opening and closing valves 70 on the first flushing pipeline 50 and the fourth main pipeline 224 are both opened, the first flushing pipeline 50 and the fourth main pipeline 224 are both connected, and the flushing water may enter the laser component analysis device 30 through the first flushing pipeline 50 and the fourth main pipeline 224, and the flushing water flushes the second pipeline assembly 22. When it is no longer necessary to flush the second pipeline assembly 22, 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 the flushing water cannot enter the fourth main pipeline 224 through the first flushing pipeline 50. When no 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.

[0074] In some embodiments of the present invention, 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 opening and closing valve 61 .

[0075] The second flushing pipeline 60 can be connected to the first pipeline assembly 21. When the electrolyte component detection system 1 needs to be flushed, the flushing water can enter the electrolyte component detection system 1 through the second flushing pipeline 60. The flushing water can flush the first pipeline assembly 21. The flushing water can take away the electrolyte in the first pipeline assembly 21, and can prepare for the subsequent detection of other types of electrolytes. The first pipeline assembly 21 can be connected to the second main pipeline 222. The flushing water in the first pipeline assembly 21 can flow into the laser component analysis device 30 through the second main pipeline 222, and then be discharged through the drain port 331 of the laser component analysis device 30.

[0076] The second flushing pipeline 60 may be provided with a fourth on-off valve 61, which may be a solenoid valve. The fourth on-off valve 61 may be selectively opened or closed. When the fourth on-off valve 61 is opened, the second flushing pipeline 60 may be conducted, and flushing water may enter the first pipeline assembly 21. When the fourth on-off valve 61 is closed, the second flushing pipeline 60 is blocked, and flushing water cannot enter the first pipeline assembly 21. By providing the first flushing pipeline 50 and the second flushing pipeline 60, flushing water may flush the first pipeline assembly 21 and the second pipeline assembly 22, thereby discharging the residual electrolyte in the pipeline assembly 20 from the electrolyte component detection system 1.

[0077] In some embodiments of the present invention, Figure 1 As shown, the electrolyte composition detection system 1 may further include: a waste discharge pipeline 80 , which is connected to the liquid discharge port 331 .

[0078] Both the flushing water and the electrolyte can be discharged from the laser component analysis device 30 through the drain port 331. The waste pipe 80 is connected to the drain port 331. The flushing water and the electrolyte can be discharged from the electrolyte component detection system 1 through the waste pipe 80, thereby achieving the effect of discharging the waste liquid from the electrolyte component detection system 1.

[0079] In some embodiments of the present invention, the electrolyte composition detection system 1 may include a controller 90, which can be communicatively connected with 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 exchange element 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 can control the operation of various components of the electrolyte composition detection system 1.

[0080] The electrolyte composition detection system 1 can also be connected to the intelligent control cabinet in the central control room for communication. Both the controller 90 and the intelligent control cabinet can achieve the effect of controlling the laser composition analysis device 30. The experimenter can control the laser composition analysis device 30 on-site through the controller 90, and the experimenter can remotely control the laser composition analysis device 30 through the intelligent control cabinet.

[0081] In an embodiment of the present application, online detection of electrolyte components may include four steps: rinsing, sampling, detection, and flushing. The embodiment of the present application is described by taking a plurality of branch pipelines 212 connected in parallel as an example.

[0082] First, before testing the electrolyte composition, the electrolyte to be tested is used to rinse the pipeline assembly 20 and the laser component analysis device 30. The first on-off valve 2122 on the branch pipeline 212 connected to the liquid storage device 10 where the electrolyte to be tested is located is opened, the second on-off valve 2221 is opened, the driving pump 2121 is started, and the electrolyte is extracted from the corresponding liquid storage device 10. The electrolyte flows to the first main pipeline 211 through the corresponding branch pipeline 212, and 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 determines that the electrolyte flows 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, the buffer tank 221, the third main pipeline 223, and the 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 determines that the electrolyte flows normally. The electrolyte enters the waste pipeline 80 through the drain port 331, and the electrolyte is discharged from the electrolyte component detection system 1. Rinse the pipeline assembly 20 and the laser component analysis device 30 with the electrolyte to be tested before sampling, which can reduce the impact of residual flushing water in the electrolyte component detection system 1 on the detection results. After rinsing, first turn off the drive pump 2121 and the first on-off valve 2122. When the second liquid flow detector 2231 detects that no electrolyte is flowing through the second liquid flow detector 2231, close the second on-off valve 2221. When no liquid flows out of the waste pipeline 80, close the drain valve 332.

[0083] Secondly, before detecting the electrolyte composition, the electrolyte to be detected is transported to the container 31. The first on-off valve 2122 on the branch pipeline 212 connected to the liquid storage device 10 where the electrolyte to be detected is located is opened, the second on-off valve 2221 is opened, the driving pump 2121 is started, and the electrolyte is extracted from the corresponding liquid storage device 10. The electrolyte flows to the laser component analysis device 30 through the first pipeline assembly 21. 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 determines that the electrolyte flows normally. When the second liquid flow detector 2231 sends a detection signal to the controller 90, the electrolyte can flow into the container 31, and the electrolyte is stored in the container 31.

[0084] Then, the electrolyte composition is detected. After the second liquid flow detector 2231 sends a detection signal to the controller 90, the driving pump 2121, the first on-off valve 2122 and the second on-off valve 2221 are closed, and the heat exchanger 32 is energized, and the heat exchanger 32 converts the liquid electrolyte in the container 31 into a solid state. The spectrum acquisition module 34 and the determination module are started, and the spectrum acquisition module 34 emits a laser to the solid electrolyte in the container 31 through the open port to obtain the spectrum data information of the electrolyte, and the determination module determines the composition of the electrolyte according to the spectrum data information.

[0085] Finally, after completing the detection of the electrolyte composition, use flushing water to flush the pipeline assembly 20 and the laser component analysis device 30. Reverse the power supply of the heat exchanger 32 to put the heat exchanger 32 in a heating state. The heat exchanger 32 converts the solid electrolyte in the container 31 into a liquid state, and the heat exchanger 32 is powered off. Open the second on-off valve 2221, the third on-off valve 70, the fourth on-off valve 61 and the drain valve 332 on the first flushing pipeline 50 and the fourth main pipeline 224, and the flushing water can enter the first pipeline assembly 21 through the second flushing pipeline 60. The flushing water cleans the first pipeline assembly 21, and the used flushing water can enter the second pipeline assembly 22 through the second main pipeline 222. The flushing water can enter the fourth main pipeline 224 through the first flushing pipeline 50, and the flushing water can clean the second pipeline assembly 22. The flushing water entering the electrolyte component detection system 1 through the first flushing pipeline 50 and the flushing water entering the electrolyte component detection system 1 through the second flushing pipeline 60 are gathered in the buffer tank 221, and the flushing water enters the container 31 through the third main pipeline 223. The flushing water can take away the liquid electrolyte in the container 31, and the flushing water cleans the container 31. The flushing water is discharged from the laser component analysis device 30 through the drain port 331, and the flushing water is discharged from the electrolyte component detection system 1 through the waste discharge pipeline 80. First, the third on-off valve 70 and the fourth on-off valve 61 on the first flushing pipeline 50 are closed. When the second liquid flow detector 2231 detects that there is no more flushing water flowing through the second liquid flow detector 2231, the second on-off valve 2221 and the third on-off valve 70 on the fourth main pipeline 224 are closed. When there is no more liquid flowing out of the waste discharge pipeline 80, the drain valve 332 is closed.
