[0071] At present, from the development of market situation, the application of power battery is more and more widely. Power battery is not only applied to energy storage power supply system such as hydroelectric power station, thermal power station, wind power station and solar power station, but also widely used in electric bicycle, electric motorcycle, electric vehicle and other electric vehicles, military equipment and aerospace and other fields. With the continuous expansion of the application field of power battery, the demand of its market is also increasing.

[0072] In its production process, it is often necessary to use material conveying equipment to transport solvent to the mixer, at the same time, the powder is put into the mixer through manual feeding operation site, so that the powder and solvent are mixed and stirred in the mixer to obtain the final product slurry.

[0073] However, in the above stirring process, the solvent used is usually trimethylbenzene. Although trimethylbenzene is a liquid, it is easy to volatilize during transportation through the pipeline in the material conveying equipment, so that the workshop where the staff work has a certain concentration of trimethylbenzene. After it is introduced into the mixer, slurry is easy to generate hydrogen sulfide gas and other gases under the action of chemical reaction. The above gas is a toxic and harmful gas. When the above gas has a high concentration in the workshop, it is easy to cause poisoning, oxygen deficiency or explosion and other adverse risks to the workers in the workshop.

[0074] Based on the above consideration, in order to solve the problem that the concentration of the above toxic and harmful gas in the workshop exceeds the standard, a slurry stirring control method and device and a production system of solid state battery are provided in the present application. The slurry stirring control method comprises: introducing powder and solvent into the mixer in the workshop, starting and stirring the powder and solvent in the mixer; obtaining the concentration of the to-be-tested gas in the predetermined area in the workshop, and comparing the concentration of the to-be-tested gas with the safety threshold; air supply to the workshop and exhaust the to-be-tested gas in the workshop; when the concentration of the to-be-tested gas is greater than the safety threshold, the mixer is controlled to stop stirring.

[0075] By detecting the concentration of the to-be-tested gas in the predetermined area in the workshop during the stirring of the powder and solvent by the mixer, the concentration information of the to-be-tested gas can be obtained in time and compared with the corresponding safety threshold, the operation of the mixer can be stopped in time when the concentration of the to-be-tested gas is greater than the safety threshold, and the concentration of the to-be-tested gas is further controlled to rise, so as to prevent the concentration of the to-be-tested gas from exceeding the standard continuously, reduce the risk of poisoning or oxygen deficiency of the workers, and reduce the risk of explosion in the workshop. The concentration of the to-be-tested gas is always kept within the safety range, the safety of the production process is improved, and the automation level is better. The concentration of the to-be-tested gas can be controlled in time and automatically, and the safety and stability are better.

[0076] It should be noted that the slurry stirring control method provided in the present application is not limited to the field of batteries. In addition to being applicable to the field of batteries, the slurry stirring control method provided in the present application can also be applied to other different technical fields. The present application does not limit the technical field of the slurry stirring control method. The slurry stirring control method can be used to stir the slurry in different fields. The slurry stirring control method provided in the present application can be used in any field where the slurry needs to be stirred.

[0077] The slurry stirring control method described in the embodiments of the present application is not limited to the field of batteries described above. For the sake of simplicity, the following embodiments will be described with reference to power batteries.

[0078] Referring to FIG. 1, and in combination with FIG. 2 and FIG. 3, a slurry stirring control method is provided according to an embodiment of the present application, comprising:

[0079] S1, the powder and the solvent are fed into the stirrer 20 in the workshop 10, the stirrer 20 is started and the powder and the solvent are stirred;

[0080] S2, the concentration of the to-be-tested gas in the predetermined area A in the workshop 10 is obtained, and the concentration of the to-be-tested gas is compared with the safety threshold;

[0081] S3, air is supplied to the workshop 10, and the to-be-tested gas in the workshop 10 is discharged;

[0082] S4, when the concentration of the to-be-tested gas is greater than the safety threshold, the stirring of the stirrer 20 is controlled to stop.

[0083] In step S1, the stirrer 20 in the workshop 10 needs to be fed with the solvent. The solvent can be transported by the material conveying device 30. At the same time, the worker manually operates the feeding position to feed the powder, so that the solvent and the powder are mixed and stirred in the stirrer 20 to obtain the slurry.

[0084] Optionally, the material conveying device 30 can be a solvent filling pipe connected to the solvent tank. The pipe is connected to the stirrer 20 to complete the filling of the solvent. A driving pump can be provided on the pipe to provide driving force for the flow of the solvent.

[0085] In step S2, the gas concentration detector can be used to obtain the gas concentration in the predetermined area A. The to-be-tested gas can be any toxic and harmful gas that may occur. The detector is used to detect the concentration of the to-be-tested gas in real time.

[0086] The predetermined area A in the workshop 10 generally refers to the main activity area of the staff, mainly for detecting the gas concentration at the area where the staff frequently move, reducing the adverse effects of harmful gas on the staff, and optionally, the detector can be placed near the manual operation position, and the detector can form a spherical detection range with a certain radius, which can be reasonably arranged according to the actual detection range covered by the detector, to ensure that the detector can cover the range where the staff frequently move, and detect the gas concentration at the position in time.

[0087] Optionally, a plurality of gas detectors can be provided according to the types of corresponding gases, and at the same time, the detectors can be arranged at multiple positions according to the activity site of the staff, to ensure that the detectors can fully cover the activity space of the staff.

[0088] The concentration of the to-be-detected gas needs to have a safety threshold. After the detection of the gas concentration is completed by the above detector, when the concentration is within the safety threshold range, the staff and equipment can work normally, and poisoning, oxygen deficiency or explosion and other adverse risks caused by too high concentration of the to-be-detected gas should be avoided. The purpose of the present application is to control the concentration of the to-be-detected gas within the safety threshold range in time.

[0089] As described in step S3, during the normal work of the staff and equipment, air needs to be supplied in the workshop 10 at the same time, so that the gas in the workshop 10 is clean after the circulation of the air flow is formed, the gas in the workshop 10 is replaced as much as possible, to ensure that the gas in the workshop 10 is clean and dry, and to a certain extent, the to-be-detected gas can be discharged, reducing the concentration of the to-be-detected gas.

[0090] During the above operation, if the concentration of the to-be-detected gas obtained by the detector exceeds the safety threshold, as described in step S4, it indicates that the concentration of the to-be-detected gas in the workshop 10 is out of standard at this time, and the equipment should be controlled to reduce the generation of the gas, that is, the mixer 20 is controlled to stop stirring, so that the adverse gas generated is also reduced.

[0091] It should be noted that under normal circumstances, in step S3, the to-be-detected gas in the workshop can be appropriately discharged by supplying air to the workshop, and the concentration of the to-be-detected gas in the workshop can generally meet the requirements of the safety threshold. The application environment in the present embodiment is that the concentration of the to-be-detected gas continuously rises and cannot be controlled when the equipment in the workshop is abnormal, and even if the ventilation in the workshop is used in step S3, the concentration cannot be reduced within the safety threshold range. At this time, step S4 needs to be used, that is, the generation source of the to-be-detected gas is controlled by controlling the mixer 20 to stop stirring, so that the concentration is reduced within the safety threshold range.

[0092] Optionally, the whole device can be checked and repaired during the process of stopping the stirring of the stirrer 20, and the concentration of the to-be-tested gas in the workshop 10 is controlled to reach the safety threshold range. After the safety threshold requirement is met, the device can be restored to operation and normal work.

[0093] The embodiment of the application provides a slurry stirring control method. The concentration of the to-be-tested gas in the predetermined area A in the workshop 10 is detected during the process of stirring the powder and the solvent by using the stirrer 20, so that the concentration information of the to-be-tested gas can be obtained in time and compared with the corresponding safety threshold. The operation of the stirrer 20 can be stopped in time when the concentration of the to-be-tested gas is greater than the safety threshold, so that the concentration of the to-be-tested gas is further controlled to rise, so as to prevent the concentration of the to-be-tested gas from continuously exceeding the standard, reduce the risk of poisoning or hypoxia of the staff, and reduce the risk of explosion in the workshop 10. The concentration of the to-be-tested gas is always kept within a safe range, better safety control of the device is formed, the safety in the production process is improved, and better automation level is achieved. The concentration of the to-be-tested gas can be controlled in time and automatically, and better safety stability is achieved.

[0094] As an optional embodiment, the step of obtaining the concentration of the to-be-tested gas in the predetermined area A in the workshop 10 and comparing the concentration of the to-be-tested gas with the safety threshold comprises the following steps.

[0095] Obtaining the concentration of a plurality of to-be-tested gases;

[0096] Comparing the concentration of the plurality of to-be-tested gases with the respective safety thresholds;

[0097] When the concentration of the to-be-tested gas is greater than the safety threshold, the step of controlling the stirrer 20 to stop stirring comprises the following steps.

[0098] When the concentration of at least one to-be-tested gas is greater than the corresponding safety threshold, the stirrer 20 is controlled to stop stirring.

[0099] Considering that there are a plurality of toxic and harmful gases in the workshop 10, the concentration of a plurality of to-be-tested gases can be obtained by using the gas detector in the embodiment. Since each different gas has a corresponding safety threshold, the concentration of the plurality of different to-be-tested gases obtained can be compared with the respective safety thresholds.

[0100] When the concentration of any one to-be-tested gas is greater than the corresponding safety threshold, that is, the concentration of the gas has exceeded the standard, the stirrer 20 needs to be controlled to stop stirring regardless of the concentration of the remaining to-be-tested gases, so as to prevent the concentration of the to-be-tested gas from further rising.

[0101] The embodiment of the present application provides a slurry stirring control method, the concentration of multiple to-be-detected gases is detected and compared with respective safety thresholds, the diversity of gas detection is improved, the concentration detection of multiple to-be-detected gases is more sufficient and comprehensive, even if only the concentration of one kind of gas exceeds the standard, the mixer 20 can also be stopped in time, the safety in the workshop 10 is further improved, and a reliable gas environment is provided for staff.

[0102] As an optional embodiment, the step of acquiring the concentration of the to-be-detected gas in the predetermined area A in the workshop 10 and comparing the concentration of the to-be-detected gas with a safety threshold comprises:

[0103] Acquiring the concentration of a first to-be-detected gas in the area around the material conveying device 30 containing solvent, and comparing the concentration of the first to-be-detected gas with a corresponding safety threshold;

[0104] When the concentration of the to-be-detected gas is greater than the safety threshold, the step of controlling the mixer 20 to stop stirring comprises:

[0105] When the concentration of the first to-be-detected gas is greater than the corresponding safety threshold, the material conveying device 30 stops running, and the mixer 20 stops stirring.

[0106] Optionally, the solvent can be mesitylene, the material conveying device 30 can be a collection of solvent tanks, driving pumps, material conveying pipelines and the like connected with each other, under normal circumstances, the driving pump can drive the solvent in the solvent tank to enter the material conveying pipeline to complete conveying, until the solvent is transported to the mixer 20.

[0107] Considering that the liquid mesitylene has a certain volatility in the transportation process, the mesitylene is volatilized into gas to form a first to-be-detected gas in the workshop 10, at this time, the detector is arranged around the material conveying device 30, and the concentration of the first to-be-detected gas can be detected synchronously and compared with the corresponding safety threshold.

[0108] If the acquired concentration of the first to-be-detected gas exceeds the safety threshold, the material conveying device 30 needs to be controlled to stop running in time, specifically, the material conveying device 30 can be controlled to suspend solvent filling, the mesitylene discharge valve is closed, and then the mixer 20 is stopped for production, so that the volatilization of mesitylene in the transportation process can be reduced in time, and finally the concentration of the first to-be-detected gas is reduced until the safety threshold range is reached.

[0110] As an optional embodiment, the step of acquiring the concentration of the to-be-detected gas in the predetermined area A in the workshop 10 and comparing the concentration of the to-be-detected gas with the safety threshold comprises:

[0111] The concentration of the second to-be-detected gas in the area around the stirrer 20 is acquired, and the concentration of the second to-be-detected gas is compared with the corresponding safety threshold;

[0113] When the concentration of the second to-be-detected gas is greater than the corresponding safety threshold, the stirrer 20 is controlled to stop stirring.

[0114] Optionally, after the mesitylene solvent is transported to the stirrer 20, a chemical reaction is prone to occur in the stirring process, so that hydrogen sulfide gas is generated and released into the workshop 10, and therefore the second to-be-detected gas around the stirrer 20 can be hydrogen sulfide gas.

[0115] In the stirring process, the detector is arranged around the stirrer 20 to detect the concentration of the generated second to-be-detected gas in time and compare the concentration with the corresponding safety threshold, if the concentration of the second to-be-detected gas exceeds the safety threshold, the operation of the stirrer 20 needs to be controlled to stop in time, specifically, the stirring action of the stirrer 20 is directly controlled to stop, so that the continuous generation of the second to-be-detected gas is reduced, and finally the concentration of the second to-be-detected gas is reduced.

[0116] The embodiment of the present application provides a slurry stirring control method, the concentration of the second to-be-detected gas around the stirrer 20 is detected and compared with the corresponding safety threshold, so that the gas environment around the stirrer 20 can be determined in time, the operation of the stirrer 20 can be stopped in time, and the stirrer 20 can be adjusted, the gas detection and the device interlocking mechanism are more targeted, and the gas reliability and safety around the stirrer 20 are improved.

[0117] As an optional embodiment, referring to FIGS. 4-6, the step of acquiring the concentration of the to-be-detected gas in the predetermined area A in the workshop 10 and comparing the concentration of the to-be-detected gas with the safety threshold comprises:

[0118] acquire the concentration of the to-be-tested gas in the predetermined area A in the workshop 10, and compare the concentration of the to-be-tested gas with the first safety threshold and the second safety threshold respectively, the first safety threshold being smaller than the second safety threshold;

[0119] when the concentration of the to-be-tested gas is greater than the safety threshold, the step of controlling the mixer 20 to stop stirring comprises:

[0120] when the concentration of the to-be-tested gas is greater than the first safety threshold and smaller than the second safety threshold, the operation of the mixer 20 is suspended intermittently;

[0121] when the concentration of the to-be-tested gas is greater than or equal to the second safety threshold, the mixer 20 is stopped.

[0122] Optionally, the first safety threshold in the embodiment can be a pre-warning value, and the second safety threshold is greater than the first safety threshold and can be a limit value, that is, when the concentration of the to-be-tested gas first exceeds the first safety threshold, the staff needs to be alerted to complete preliminary concentration adjustment, and when the concentration of the to-be-tested gas continues to rise and exceeds the second safety threshold, the equipment needs to be completely stopped.

[0123] Specifically, when the obtained concentration of the to-be-tested gas is between the first safety threshold and the second safety threshold, the device can be controlled to suspend operation, for example, the mixer 20 is controlled to suspend stirring action, or the discharge valve of the material conveying device 30 is temporarily closed, so that the concentration of the to-be-tested gas is temporarily reduced until it is controlled within the first safety threshold.

[0124] When the concentration of the to-be-tested gas exceeds or is equal to the second safety threshold, the concentration of the to-be-tested gas has been seriously exceeded, and all the equipment needs to be immediately stopped, the material conveying device 30 stops solvent filling, the off three methylbenzene discharge valve is closed, the mixer 20 stops production, and the operator is reminded to evacuate.

[0125] The embodiment of the application provides a slurry stirring control method, by setting the safety threshold as the first safety threshold and the second safety threshold, the detected concentration of the to-be-tested gas forms a ladder type judgment process, and then different equipment actions are obtained, the specific threshold range can be judged according to the specific threshold range, on the basis of ensuring that the concentration is exceeded, the process smoothness can be ensured to a certain extent, the process efficiency is appropriately ensured, the influence of equipment shutdown on the process progress is reduced, and more optimal targeted judgment is obtained.

[0126] As an optional embodiment, the control method further comprises: when the concentration of the to-be-tested gas is greater than the safety threshold, sending a ventilation signal to the ventilation device 40 to increase the air supply rate.

[0127] The embodiment utilizes the linkage between the concentration of the to-be-tested gas and the ventilation device 40 to further reduce the concentration of the to-be-tested gas. When the detected concentration of the to-be-tested gas exceeds the safety threshold, the ventilation device 40 can receive a ventilation signal, thereby further increasing the air supply rate on the basis of the original ventilation of the workshop 10 to make the to-be-tested gas be discharged from the workshop 10 as soon as possible.

[0128] That is, the embodiment further controls the ventilation rate of the ventilation device 40 on the basis of stopping the operation of the mixer 20 by comparing the actual concentration with the safety threshold, thereby greatly reducing the concentration of the to-be-tested gas in the workshop 10.

[0129] The embodiment provides a slurry stirring control method. The concentration of the to-be-tested gas is linked with the ventilation device 40, thereby being beneficial to controlling the operation of the ventilation device 40 according to the actual gas concentration, making the ventilation device 40 better adapt to different actual gas environments, making corresponding judgments according to the actual concentration value, and completing ventilation adjustment of the gas concentration in a targeted manner to meet the specification requirements of the gas concentration as soon as possible.

[0130] Optionally, when the concentration of the to-be-tested gas is greater than the safety threshold, the step of sending a ventilation signal to the ventilation device 40 to increase the air supply rate comprises: the mixer 20 sends a first interaction signal to the ventilation device 40, and the ventilation device 40 sends a second interaction signal to the mixer 20, so as to form real-time signal intercommunication between the two.

[0131] Optionally, the first interaction signal and the second interaction signal are actually a kind of detection analog signal, and the main function is to ensure the signal intercommunication between the mixer 20 and the ventilation device 40, to ensure that the two can normally transmit signals and avoid the influence of signal interruption.

[0132] Actually, the above-mentioned interaction signal belongs to heartbeat interaction, and the real-time heartbeat interaction signal is interchecked to confirm whether the communication is abnormal. When the signal is abnormal, the mixer 20 cannot continue to produce until the interaction signal returns to normal, and the first interaction signal and the second interaction signal are both real-time effective, and are bidirectional interaction for mutual communication.

[0133] The embodiment provides a slurry stirring control method. The ventilation device 40 and the mixer 20 perform real-time signal interaction, ensure the signal intercommunication of the two in the running process, reduce the risk of signal interruption, and further reduce the possibility that the two cannot perform signal interaction, thereby providing reliable protection for stable signal transmission between the concentration data of the gas and ventilation adjustment, and making the devices be able to complete smooth operation.

[0134] As an optional embodiment, when the concentration of the to-be-tested gas is greater than the safety threshold, the step of sending the ventilation signal to the ventilation device 40 to increase the air supply rate comprises:

[0135] When the concentration of the to-be-tested gas is greater than the first safety threshold and less than the second safety threshold, the ventilation device 40 supplies air to the predetermined area A at a first air speed;

[0136] When the concentration of the to-be-tested gas is greater than or equal to the second safety threshold, the ventilation device 40 supplies air to the predetermined area A at a second air speed, wherein the second air speed is greater than the first air speed.

[0137] When the concentration of the to-be-tested gas is between the first safety threshold and the second safety threshold, it indicates that the actual concentration at this time has exceeded the warning value, and at this time the ventilation device 40 supplies air at the first air speed after receiving the ventilation signal, which can be understood as relatively low-speed operation, thereby timely discharging the to-be-tested gas in the workshop 10.

[0138] When the concentration of the to-be-tested gas exceeds or is equal to the second safety threshold, it indicates that the actual concentration at this time has exceeded the limit value, and at this time the ventilation device 40 adjusts to supply air at the second air speed after receiving the ventilation signal, which can be understood as relatively high-speed operation, thereby timely discharging the to-be-tested gas in the workshop 10.

[0139] In fact, the ventilation device 40 can also be divided into multiple gear ventilation speeds according to the actual measured gas concentration, and is not limited to the first air speed and the second air speed in the above embodiment. According to the actual different concentration, the corresponding multiple gear air speed is adjusted, so as to better adapt to the corresponding gas concentration.

[0140] The embodiment of the application provides a slurry stirring control method, by dividing the safety threshold into a first safety threshold and a second safety threshold, and forming signal interaction between the running air speed of the ventilation device 40 and the above threshold range, so that the ventilation device 40 can adjust the actual running air speed according to the actual gas concentration, thereby better adapting to the corresponding gas concentration environment, more targetedly completing the concentration adjustment of the to-be-tested gas, and more efficiently completing the gas adjustment process in the workshop 10.

[0141] As an optional embodiment, the control method further comprises:

[0142] Obtaining the concentration of oxygen in the workshop 10, and comparing the concentration of oxygen with the corresponding oxygen safety threshold of oxygen;

[0143] When the concentration of oxygen is less than the corresponding oxygen safety threshold of oxygen, the concentration of oxygen in the predetermined area A is increased.

[0144] In view of the oxygen demand of the workers in the workshop 10, the predetermined area A is usually the frequent activity area of the workers, and therefore, the change of the oxygen concentration in the predetermined area A is focused on in the embodiment.

[0145] Optionally, an oxygen concentration detector can be arranged in the predetermined area A, and the detector is ensured to sufficiently cover the predetermined area A, so that the oxygen concentration can be detected in real time, and the detected oxygen concentration is compared with the corresponding oxygen safety threshold.

[0146] When the oxygen concentration in the predetermined area A is low, the workers in the workshop 10 are prone to hypoxia, and therefore, the oxygen concentration in the predetermined area A needs to be increased in time until the oxygen demand of the workers is met.

[0147] The embodiment of the application provides a slurry stirring control method, which further detects the oxygen concentration and adjusts the oxygen concentration according to the actual oxygen concentration, so that the oxygen concentration in the workshop 10 always reaches the specified range, ensures that the oxygen environment in the workshop 10 reaches the standard, provides a safe and reliable aerobic environment for the workers, and further improves the safety of the workshop 10.

[0148] As an optional embodiment, the control method further comprises:

[0151] Optionally, when the stirrer 20 is stirring, inert gas such as nitrogen is often introduced into the stirrer 20 through a gas pipeline. When the oxygen concentration is low after the above oxygen concentration detection, the oxygen concentration can be adjusted by controlling the delivery of the inert gas.

[0152] This is because the inert gas may leak during delivery, which can easily cause the oxygen concentration in the predetermined area A to be too low. If the valve of the gas pipeline is controlled to stop the delivery of the inert gas at this time, the possibility of inert gas leakage can be reduced, thereby indirectly increasing the oxygen concentration in the area until the oxygen concentration returns to the safety threshold range.

[0153] The embodiment of the present application provides a slurry stirring control method, which compares the concentration of oxygen with the oxygen safety threshold after the concentration of oxygen is obtained, and provides a method for adjusting the oxygen concentration, that is, the input amount of inert gas required by the stirrer 20 is adjusted to adjust the oxygen concentration in the workshop 10, the emission of inert gas in the workshop 10 is reduced, the oxygen adjustment in the workshop 10 can be effectively completed in time, the adjustment efficiency and the adjustment effect are better, and the oxygen concentration can always meet the standard.
