With the development of the lithium battery industry, people are paying increasing attention to the performance of lithium batteries and their large-scale production.

[0005] As a crucial step in battery manufacturing, the production of battery slurry directly impacts various battery performance characteristics, thus attracting increasing attention. Existing slurry production equipment is susceptible to fluctuations in slurry quality, even resulting in substandard slurry, due to factors such as container feeding and valve operation. Therefore, this problem urgently needs to be addressed.

Detailed Implementation

[0091] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0092] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0093] In this application, "multiple" or "more than" refers to two or more (including two). In this application, "several items" or "multiple items" refers to two or more (including two).

[0094] In this embodiment of the application, the battery can be a secondary battery, which refers to a battery that can be used again after being discharged by recharging to activate the active materials.

[0095] Batteries may include, but are not limited to, lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride battery cells, nickel-cadmium batteries, lead-acid batteries, etc.

[0096] As an example, the battery can be a cylindrical battery, a prismatic battery cell, or a battery of other shapes. Prismatic battery cells include prismatic batteries, blade-shaped batteries, and multi-prismatic batteries, such as hexagonal prismatic batteries. This application does not have any particular limitations.

[0097] Battery slurry typically refers to a mixture of electrode materials used in battery manufacturing. It is generally a suspension composed of active materials, conductive agents, binders, and solvents, primarily used to create the positive and negative electrodes. The combination and proportion of the components in the battery slurry directly affect the battery's performance and lifespan. The quality of the battery slurry directly impacts the battery's performance, cycle life, and safety. Therefore, the preparation and processing of the slurry are crucial in battery manufacturing.

[0098] The process of preparing battery slurry typically involves mixing active materials, conductive agents, and binders with solvents in a specific ratio to form a homogeneous suspension, i.e., battery slurry. The mixing process generally utilizes a slurry container equipped with a stirring assembly.

[0099] For ease of explanation, we will use slurry production equipment as an example.

[0100] Figure 1 is a schematic diagram of a slurry production equipment provided in some embodiments of this application.

[0101] As shown in Figure 1, the slurry production equipment 100 includes a slurry container 110, a powder feeding assembly 120, and a solvent feeding assembly 130. The slurry container 110 is internally equipped with a stirring assembly 111 and a regulating assembly for adjusting the internal environmental pressure of the slurry container 110; the regulating assembly includes a cooling assembly 112 disposed on the outer wall of the slurry container, a vacuuming assembly 113 communicating with the interior of the slurry container 110, and a protective gas filling assembly 114.

[0102] When the slurry production equipment 100 is operating, the mixing component 111 operates normally. The pressure and temperature inside the slurry container 110 fluctuate due to friction between components and valve opening / closing, leading to air pockets in the slurry, abnormal mixing, and affecting the quality of the output slurry, even causing it to be scrapped. Furthermore, when feeding material into the slurry container 110, the internal pressure can rise continuously, affecting slurry quality. Excessive fluctuations in pressure and temperature inside the slurry container 110 pose a risk of scrapping or explosion. Therefore, controlling the relative stability of the internal pressure and temperature of the slurry container 110 is a crucial issue for achieving normal slurry production.

[0103] To address the aforementioned problems, embodiments of this application provide a control method for a slurry production equipment 100. The method includes: detecting real-time operating parameters of the slurry production equipment 100, the operating parameters including a first parameter value characterizing the ambient temperature inside the slurry container 110 and a second parameter value characterizing the ambient pressure inside the slurry container 110; obtaining a first deviation value based on the first parameter value and a first preset threshold range; obtaining a second deviation value based on the second parameter value and a second preset threshold range; and adjusting the operating parameters of the stirring assembly 111 and / or controlling the environmental conditions inside the slurry container 110 based on the first deviation value and / or the second deviation value, thereby controlling the stability of the slurry inside the slurry container 110. By automatically detecting the real-time operating parameters of the slurry production equipment 100, calculating them against the preset first and second preset threshold ranges corresponding to the target slurry, and triggering control conditions based on the deviation of the real-time detected parameters from the preset parameters, the operating parameters of the stirring component 111 and / or the operating parameters of the adjusting component are adjusted accordingly, thereby controlling the environmental conditions inside the slurry container 110, such as temperature and pressure, and automatically achieving stable production of slurry inside the slurry container 110.

[0104] The control method of the battery slurry production equipment provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings. Please refer to Figures 2 to 8.

[0105] Figure 2 is a schematic flowchart of a control method for a battery slurry production equipment according to an embodiment of this application.

[0106] Please refer to Figure 2. The control method for the battery slurry production equipment includes steps 101 to 104.

[0107] Step 101: Detect the real-time operating parameters of the slurry production equipment 100. The operating parameters include a first parameter value for characterizing the ambient temperature inside the slurry container 110 and a second parameter value for characterizing the ambient pressure inside the slurry container 110.

[0108] In this step, it was found that the ambient temperature and pressure inside the slurry container 110 have a significant impact on the slurry quality. The fluctuation range of the first and second parameter values ​​also has a substantial effect on the slurry quality. Therefore, relevant equipment was installed to detect and obtain the first parameter value of the ambient temperature and the second parameter value of the ambient pressure inside the slurry container 110 in real time. For example, pressure sensors and temperature sensors can be installed inside the slurry container 110 to obtain the first and second parameter values ​​in real time, respectively. The pressure and temperature sensors are connected to the outside to transmit the first and second parameter values.

[0109] Step 102: Obtain the first deviation value based on the first parameter value and the first preset threshold range.

[0110] In this step, it is found that a first parameter value used to characterize the ambient temperature inside the slurry container 110, when within a first preset threshold range, can reduce slurry quality fluctuations and improve the consistency of slurry quality across different batches. Therefore, the deviation of the first parameter value from the first preset threshold range is calculated so that the first deviation value can be used to control the ambient temperature inside the slurry container 110 in real time, ensuring that the ambient temperature inside the slurry container 110 in the operating slurry production equipment 100 remains within the first preset threshold range.

[0111] For example, the first deviation value can be calculated as follows: if the first parameter value is greater than the upper threshold of the first preset threshold range, the first deviation value = the first parameter value - the upper threshold of the first preset threshold range; if the first parameter value is less than the lower threshold of the first preset threshold range, the first deviation value = the first parameter value - the lower threshold of the first preset threshold range; if the lower threshold of the first preset threshold range ≤ the first parameter value ≤ the upper threshold of the first preset threshold range, the first deviation value is zero. When the first deviation value is zero, the slurry production equipment 100 operates with preset normal parameters.

[0112] Step 103: Obtain the second deviation value based on the second parameter value and the second preset threshold range.

[0113] In this step, it was found that the value of the second parameter used to characterize the environmental pressure inside the slurry container 110, when within a second preset threshold range, can reduce slurry quality fluctuations and improve the consistency of slurry quality across different batches. Therefore, the deviation of the second parameter value from the second preset threshold range is calculated so that the environmental pressure inside the slurry container 110 can be controlled in real time using this deviation value, ensuring that the internal environmental pressure of the slurry container 110 in the operating slurry production equipment 100 remains within the second preset threshold range.

[0114] For example, the second deviation value can be calculated as follows: if the second parameter value is greater than the upper threshold of the second preset threshold range, the second deviation value = the second parameter value - the upper threshold of the second preset threshold range; if the second parameter value is less than the lower threshold of the second preset threshold range, the second deviation value = the second parameter value - the lower threshold of the second preset threshold range; if the lower threshold of the second preset threshold range ≤ the second parameter value ≤ the upper threshold of the second preset threshold range, the second deviation value is zero. When the second deviation value is zero, the slurry production equipment 100 operates with preset normal parameters.

[0115] Step 104: Adjust the operating parameters of the stirring assembly 111 and / or control the environmental conditions inside the slurry container 110 according to the first deviation value and / or the second deviation value, so as to control the stability of the slurry inside the slurry container 110.

[0116] According to the embodiments of this application, this method is applied during the operation of the slurry production equipment 100 or during the slurry preparation process. It detects the real-time operating parameters of the slurry production equipment 100, adjusts the operating parameters of the stirring component 111 based on the first deviation value of the real-time obtained first parameter value from a first preset threshold range, and adjusts the environmental conditions inside the slurry container 110 based on the second deviation value of the real-time obtained second parameter value from a second preset threshold range. This allows for the stabilization of pressure and temperature inside the slurry container 110, reduces air bubbles in the slurry, ensures that the slurry mixes and reacts at the most suitable temperature, achieves stable slurry quality, and produces high-quality slurry. The entire process is highly automated, reduces labor costs, and allows for the rapid and batch production of stable-quality slurry, achieving stable and continuous slurry production.

[0117] In particular, when the slurry production equipment 100 is running, the addition of powder and solvent causes the opening of the corresponding powder and solvent valves, resulting in significant fluctuations in pressure and temperature inside the slurry container 110, which affects slurry quality to some extent. If the equipment is stopped for powder addition or solvent addition, continuous production cannot be achieved, and the slurry in the container 110 still faces significant pressure and temperature fluctuations. The control method of this application accurately and in real-time detects the pressure and temperature inside the slurry container 110 and dynamically adjusts them, further achieving relative stability of the pressure and temperature inside the container 110. This allows for the rapid and batch production of slurry with stable quality, enabling stable and continuous slurry production.

[0118] The following describes the method provided in this application for controlling slurry production equipment to adjust the direction of a first parameter value:

[0119] In some alternative implementations, prior to step 101, the method further includes:

[0120] Obtain the data parameters of the target slurry;

[0121] Based on the data parameters of the target slurry, a first preset threshold range for the battery slurry temperature is obtained.

[0122] In this embodiment of the application, the data parameters of the target slurry can be retrieved from the stored data in the system or obtained manually by relevant personnel. Based on the data parameters of the target slurry, a first preset threshold range of battery slurry temperature can be obtained, so that the slurry inside the slurry container 110 is in a more suitable preset temperature range during the preparation process, namely the first preset threshold range.

[0123] In some optional embodiments, the method further includes: a first parameter value within a first preset threshold range; a second parameter value within a second preset threshold range; and the stirring assembly 111 operating with predetermined operating parameters.

[0124] In this embodiment, the ambient temperature and ambient pressure inside the slurry container 110 are within a predetermined range, and the stirring component 111 operates with predetermined operating parameters, so as to facilitate the production of batches of slurry with the correct quality and temperature while taking into account the slurry production efficiency.

[0125] In some optional implementations, in step 101, the first preset threshold range includes an upper threshold temperature.

[0126] Accordingly, step 104 specifically includes adjusting the operating parameters of the stirring assembly 111 and / or controlling the environmental conditions inside the slurry container 110 based on the first deviation value and / or the second deviation value, i.e., controlling the environmental conditions inside the slurry container 110 through the adjusting assembly:

[0127] If the first parameter value is greater than the upper temperature threshold, the stirring component 111 operates with the first operating parameter.

[0128] In this embodiment, if the first parameter value is greater than the upper temperature threshold, i.e. the first deviation value is positive, the stirring component 111 operates with the first operating parameter. If the first operating parameter is less than the predetermined operating parameter, the speed of the stirring component 111 decreases, so that the ambient temperature inside the slurry container 110 drops.

[0129] In some optional embodiments, when the first parameter value is greater than the upper temperature threshold, and the stirring assembly 111 operates in a mode with the first operating parameter, the method further includes:

[0130] Based on the data parameters of the target slurry, the first parameter value, and the first operating parameters, the first temperature change rate of the target slurry is obtained;

[0131] The first delay time is obtained based on the first temperature change rate;

[0132] According to the first delay waiting time, the stirring assembly 111 operates with the first operating parameters for the first delay waiting time.

[0133] In this embodiment, by acquiring the target slurry data parameters, the first parameter value, and the first operating parameters, the temperature change of the stirring component 111 after operating under the first operating parameters can be calculated. After the stirring component 111 operates under the first operating parameters for a first delay waiting time, the method enables the first parameter value to be detected quickly and is adjusted in real time to automatically restore it to the preset temperature range, reducing the fluctuation of the first parameter value, reducing the error rate of manual monitoring and adjustment, and making it more convenient and efficient.

[0134] Then, when the first parameter value returns to the first preset threshold range, the stirring component 111 operates at a normal speed.

[0135] In some optional embodiments, the regulating component includes a cooling component 112 disposed on the outer wall of the slurry container 110; the method further includes: when the first parameter value is within a first preset threshold range, the cooling component 112 operates at a first cooling rate.

[0136] In this embodiment of the application, when the slurry production equipment 100 is producing slurry, the stirring component 111 is operating normally, and the cooling component 112 is operating at a first cooling rate under normal production conditions, so as to avoid the slurry from heating up too quickly during the production process and reduce the rapid temperature rise inside the slurry container 110.

[0137] In some optional embodiments, when the first parameter value is greater than the upper temperature threshold, and the stirring assembly 111 operates in a mode with the first operating parameter, the method further includes:

[0138] Step 107, the cooling component 112 operates at a second cooling rate, which is greater than the first cooling rate.

[0139] In this embodiment, when the first parameter value is greater than the upper temperature threshold, the stirring component 111 operates in the mode of the first operating parameter. At this time, the temperature needs to be reduced. When the first parameter value is detected to be greater than the upper temperature threshold, the cooling speed can be accelerated immediately. Even if the cooling component 112 operates at the second cooling speed, the fluctuation of the first parameter value is reduced, and it is automatically restored to the preset temperature, reducing the error rate and delay of manual monitoring and adjustment.

[0140] Then, when the first parameter value returns to the first preset threshold range, the stirring component 111 operates at a normal speed.

[0141] In some alternative implementations, the first preset threshold range includes a threshold value at a certain temperature;

[0142] Step 104, which involves adjusting the operating parameters of the stirring assembly 111 and / or controlling the internal environmental conditions of the slurry container 110 based on the first deviation value and / or the second deviation value, includes:

[0143] If the first parameter value is less than the threshold value at the temperature, the cooling component 112 operates at a third speed, which is less than the first cooling speed.

[0144] In this embodiment, the first parameter value is less than the threshold value at the temperature, that is, the first deviation value is negative and the temperature is low. Therefore, it is necessary to increase the ambient temperature inside the slurry container 110. The cooling rate can be reduced immediately when the first parameter value is detected to be less than the threshold value at the temperature. Even if the cooling component 112 is running at the third cooling rate, the fluctuation of the first parameter value is reduced, and it is automatically restored to the preset temperature, reducing the error rate and delay of manual monitoring and adjustment.

[0145] For example, the third speed can be zero, i.e., the operation of the cooling component 112 is suspended.

[0146] In some alternative implementations, where the first parameter value is less than a threshold value at the temperature, and the cooling assembly 112 operates in a third-speed mode, the method further includes:

[0147] Based on the data parameters of the target slurry and the first operating parameters of the stirring assembly 111, the second temperature change rate of the target slurry is obtained;

[0148] The second delay time is obtained based on the second temperature change rate;

[0149] The second delay waiting time is the time during which the cooling component 112 operates at the third speed, based on the second delay waiting time.

[0150] In this embodiment, by acquiring the target slurry data parameters, the first parameter value, and the first operating parameters, the temperature change of the cooling component 112 after running at the third speed can be calculated, and the first parameter value after the cooling component 112 runs at the third speed for a second delay can be calculated. This method enables the first parameter value to be detected quickly and adjusted in real time to automatically restore it to the preset temperature range, reducing the fluctuation of the first parameter value, restoring the first parameter value to the first preset threshold range, and automatically restoring it to the preset temperature. This reduces the error rate of manual monitoring and adjustment, making it more convenient and efficient.

[0151] In some optional embodiments, after the second delay waiting time is defined as the time during which the cooling component 112 operates at the third speed, the method further includes:

[0152] When the first parameter value is within the range of the first preset threshold, the cooling component 112 operates at a first cooling rate.

[0153] In this embodiment, after the second delay waiting time, the cooling component 112 runs at the third speed for the time specified in the second delay waiting time, i.e., the first parameter value is within the range of the first preset threshold, the cooling component 112 continues to run at the first cooling speed, and the slurry production equipment 100 operates normally.

[0154] In some alternative implementations, the method includes:

[0155] If the value of the first parameter is greater than the upper temperature threshold, a first alarm signal is triggered.

[0156] In this embodiment, if the first parameter value is greater than the upper temperature threshold, i.e., the first deviation value is positive, a first alarm signal is triggered to draw the attention of the staff and facilitate the viewing and understanding of the operating status of the slurry production equipment 100. The first alarm signal may include information that the first parameter value is greater than the upper temperature threshold.

[0157] In some alternative implementations, the method includes: triggering a second alarm signal when the value of a first parameter is less than a threshold value at the temperature.

[0158] In this embodiment, the first parameter is less than the threshold value at the temperature, i.e., the first deviation value is negative, so as to attract the attention of the staff and facilitate the observation and understanding of the operating status of the slurry production equipment 100. The second alarm signal may include information that the first parameter is less than the threshold value at the temperature.

[0159] In some optional implementations, the first preset threshold range further includes a temperature shutdown upper threshold; when the first parameter value is greater than or equal to the temperature shutdown upper threshold, the slurry production equipment 100 shuts down and / or enters a safety interlock mode. The safety interlock foolproof mode in case of abnormal temperature can protect the slurry being prepared in the event of an abnormal temperature inside the slurry container 110, which is beneficial for saving raw materials.

[0160] In some optional implementations, the first preset threshold range further includes a temperature shutdown threshold; when the first parameter value is less than or equal to the temperature shutdown threshold, the slurry production equipment 100 shuts down and / or enters a safety interlock mode. The safety interlock foolproof mode in case of abnormal temperature can protect the slurry being prepared in the event of an abnormal temperature inside the slurry container 110, which is beneficial for saving raw materials.

[0161] Figure 3 shows a schematic diagram of the first parameter value and time curve of the slurry container provided in the embodiment of this application; in the figure, A represents the lower threshold value of temperature shutdown at time t1, and B represents the upper threshold value of temperature shutdown at time t2. Wherein, the lower threshold value of temperature shutdown < the lower threshold value of temperature shutdown ≤ the upper threshold value of temperature shutdown < the upper threshold value of temperature shutdown.

[0162] In some optional implementations, the temperature threshold is equal to the temperature threshold. That is, the first preset threshold range is a single value. When the first parameter value is not equal to the first preset threshold range (a single point value), control is performed by the control method of the above embodiment to keep the first parameter value within the first preset threshold range.

[0163] The following describes the method provided in this application for controlling slurry production equipment to adjust the direction of the second parameter value:

[0164] In some optional implementations, the method further includes:

[0165] Obtain the data parameters of the target slurry;

[0166] Based on the data parameters of the target slurry, a second preset threshold range for battery slurry pressure is obtained.

[0167] In this embodiment of the application, the data parameters of the target slurry can be retrieved from the stored data in the system or obtained manually by relevant personnel. Based on the data parameters of the target slurry, a second preset threshold range of battery slurry pressure can be obtained, so that the slurry inside the slurry container 110 is in a more suitable preset pressure range, namely the second preset threshold range.

[0168] In some optional embodiments, the second preset threshold range includes an upper pressure threshold; the adjustment component includes a vacuum assembly 113;

[0169] Step 104 specifically includes adjusting the operating parameters of the stirring assembly 111 and / or controlling the environmental conditions inside the slurry container 110 based on the first deviation value and / or the second deviation value, i.e., controlling the environmental conditions inside the slurry container 110 through the adjusting assembly:

[0170] If the second parameter value is greater than or equal to the upper pressure threshold, the vacuum assembly 113 operates with the second operating parameter.

[0171] In this embodiment, the second parameter value is greater than or equal to the pressure threshold, that is, the second deviation value of the second parameter value is positive, that is, the pressure inside the slurry container 110 is large and it is necessary to reduce the pressure inside the slurry container 110. At this time, the vacuum assembly 113 operates with the second operating parameters and can adjust the pressure inside the slurry container 110 in real time.

[0172] In some optional embodiments, when the vacuum assembly 113 operates in a mode with a second operating parameter, the method further includes:

[0173] The first pressure change rate of the slurry container 110 is obtained based on the second operating parameters, the second preset threshold range, and the second parameter value.

[0174] The third delay waiting time is obtained based on the first pressure change rate;

[0175] According to the third delay waiting time, the vacuum pumping component 113 is shut down after running with the second operating parameters for the third delay waiting time.

[0176] In this embodiment, the pressure change inside the slurry container 110 after the vacuum assembly 113 operates with the second operating parameters, the second preset threshold range, and the second parameter value can be calculated. The second parameter value after a third delay waiting time when the vacuum assembly 113 operates with the second operating parameters can also be calculated. At this point, the second parameter value returns to the second preset threshold range, and the vacuum assembly 113 is shut down. This method allows the second parameter value to be detected quickly and adjusted automatically to return to the preset pressure range, reducing fluctuations in the second parameter value, minimizing the error rate and delay of manual monitoring and adjustment, and making it more convenient and efficient.

[0177] In some alternative embodiments, the vacuum assembly 113 includes an exhaust valve. When the slurry container 110 is fed, the feeding causes the vacuum pressure inside the slurry container 110 to continuously increase, and the pressure can be stabilized by controlling the opening and closing of the exhaust valve.

[0178] Furthermore, in the operating mode where the exhaust valve is open, the method further includes:

[0179] The first pressure change rate of the slurry container 110 is obtained based on the opening of the exhaust valve, the second preset threshold range, and the second parameter value.

[0180] The third delay waiting time is obtained based on the first pressure change rate;

[0181] Based on the third delay waiting time, the exhaust valve is opened for the third delay waiting time and then closed. This setting, combined with the opening of the exhaust valve and the first pressure change rate, allows for rapid pressure stabilization.

[0182] In some optional embodiments, the second preset threshold range includes a pressure threshold; the adjustment component includes a protective gas inflation component 114;

[0183] The step of adjusting the operating parameters of the stirring assembly 111 and / or controlling the environmental conditions inside the slurry container 110 based on the first deviation value and / or the second deviation value includes:

[0184] If the second parameter value is less than or equal to the pressure threshold, the protective gas inflation assembly 114 operates with the fourth operating parameter.

[0185] In this embodiment, the second parameter value is less than or equal to the pressure threshold, that is, the second deviation value of the second parameter value is negative. The protective gas filling component 114 operates with the fourth operating parameter, which can fill the slurry container 110 with protective gas and increase the second parameter value of the slurry container 110.

[0186] For example, the protective gas filling component 114 can fill the slurry container 110 with nitrogen, argon, or the like, thereby increasing the vacuum pressure in the slurry container 110.

[0187] In some optional embodiments, the protective gas inflation assembly 114 operates in a fourth operating parameter mode, and the method further includes:

[0188] The second pressure change rate of the slurry container 110 is obtained based on the fourth operating parameter, the second preset threshold range, and the second parameter value.

[0189] The fourth delay waiting time is obtained based on the second pressure change rate;

[0190] According to the fourth delay waiting time, the protective gas inflation component 114 is shut down after running for the fourth delay waiting time.

[0191] In this embodiment, the pressure change inside the slurry container 110 after the protective gas inflation component 114 operates with the fourth operating parameter, the second preset threshold range, and the second parameter value can be calculated. The second parameter value after a fourth delay waiting time can also be calculated. At this point, the second parameter value returns to the second preset threshold range, and the fourth operating parameter is turned off. This method allows the second parameter value to be detected quickly and adjusted automatically to return to the preset pressure range, reducing fluctuations in the second parameter value, minimizing the error rate and delay of manual monitoring and adjustment, and making it more convenient and efficient.

[0192] In some alternative implementations, if the second parameter value is greater than the pressure threshold, a third alarm is issued.

[0193] In this embodiment, if the second parameter value is greater than the upper pressure threshold, i.e., the second deviation value is positive, a third alarm signal is triggered to draw the attention of the staff and facilitate the inspection and understanding of the operating status of the slurry production equipment 100. The third alarm signal may include information that the second parameter value is greater than the upper pressure threshold.

[0194] In some alternative implementations, a fourth alarm is issued when the value of the second parameter is less than the pressure threshold.

[0195] In this embodiment, if the second parameter value is less than the lower pressure threshold (i.e., the second deviation value is negative), a fourth alarm signal is triggered to draw the attention of personnel and facilitate the inspection and understanding of the operating status of the slurry production equipment 100. The fourth alarm signal may include information that the second parameter value is less than the upper pressure threshold.

[0196] In some optional embodiments, the second preset threshold range includes a pressure shutdown upper threshold. When the second parameter value is greater than or equal to the pressure shutdown upper threshold, the slurry production equipment 100 enters a safety interlock mode and / or shuts down. The safety interlock foolproof mode in case of pressure abnormalities can protect the slurry being prepared in the event of abnormal temperature within the slurry container 110, thus helping to save raw materials.

[0197] In some optional embodiments, the second preset threshold range includes a pressure shutdown threshold; when the second parameter value is less than or equal to the pressure shutdown threshold, the slurry production equipment 100 enters a safety interlock mode and / or shuts down. The safety interlock foolproof mode in case of abnormal pressure can protect the slurry being prepared in the event of abnormal temperature within the slurry container 110, thus saving raw materials.

[0198] Figure 4 shows a schematic diagram of the second parameter value and time curve of the slurry container provided in the embodiment of this application; in the figure, C represents the upper threshold value of pressure shutdown at time t3, and D represents the lower threshold value of temperature shutdown at time t4. Wherein, the lower threshold value of pressure shutdown < the lower threshold value of pressure ≤ the upper threshold value of pressure < the upper threshold value of pressure shutdown.

[0199] In some optional implementations, the upper pressure threshold is equal to the lower pressure threshold. That is, the second preset threshold range is a single value. When the second parameter value is not within the second preset threshold range, control is performed using the control method described in the above embodiments to keep the second parameter value within the second preset threshold range.

[0200] In related technologies, the lower body of the slurry container 110 is vertically movable for subsequent maintenance. Please refer to Figure 6, which shows a schematic diagram of a slurry container according to an embodiment of this application.

[0201] As shown in Figure 6, the slurry container 110 includes a first barrel 101 and an extension 102. The first barrel 101 and the extension 102 are connected to form a sealed containing space. The first barrel 101 is movably connected to the extension 102 in a first direction X. The first barrel 101 is movable relative to the extension 102 in the first direction X. A stirring assembly 111 is provided inside the slurry container 110. The first direction X can be vertical. The first barrel 101 can be a lower barrel. The first barrel 101 of the slurry container 110 is movable relative to the extension 102 in the vertical direction, which facilitates the cleaning and maintenance of the stirring assembly 111 and the inner wall of the slurry container 110. However, since the first barrel 101 is designed to be movable, when the slurry production equipment 100 is running, due to the stirring of the slurry inside the slurry container 110 and the long-term suspension of the lower part of the slurry container 110, the first barrel 101 may shift downward to a certain extent, which may disrupt the vacuum environment and pressure inside the slurry container 110, making the airtightness of the slurry container 110 worse and causing air to leak into the slurry container 110; it may also affect the operating effect of the stirring assembly 111.

[0202] Based on the above-mentioned problems, embodiments of this application provide a control method for a slurry production equipment 100. The method includes: detecting real-time operating parameters of the slurry production equipment 100, the operating parameters including a second parameter value characterizing the environmental pressure inside the slurry container 110; and, based on the fact that the difference between any two of the second parameter values ​​in any two adjacent time intervals is greater than a first preset pressure value, causing the first tank 101 to return to its initial position in a sealed state in a first direction X. By judging the multiple second parameter values ​​and causing the first tank 101 to return to its initial position in a sealed state in the first direction X, the environmental conditions inside the slurry container 110, such as pressure, can be controlled, thereby automatically achieving stable production of slurry inside the slurry container 110.

[0203] Figure 5 is a schematic flowchart of a control method for a battery slurry production equipment according to an embodiment of this application.

[0204] Please refer to Figure 5. The control method for the battery slurry production equipment includes steps 101 and 108.

[0205] Step 101: Detect the real-time operating parameters of the slurry production equipment 100, the operating parameters including a second parameter value for characterizing the environmental pressure inside the slurry container 110;

[0206] Step 108: If the difference between any two of the second parameter values ​​in any two adjacent time intervals is greater than the first preset pressure value, the first barrel 101 is restored to its initial position in the first direction X to a sealed state.

[0207] In this embodiment, by acquiring multiple second parameter values, when the difference between any two second parameter values ​​in any two adjacent time intervals is greater than the first preset pressure value, the first barrel 101 is restored to its initial position in the first direction X, which is a sealed state. This setting can prevent the lower barrel of the slurry container 110 from settling during the mixing and pulping process, while ensuring the airtightness of the slurry container 110.

[0208] For example, the return of the lower barrel of the slurry container 110 to its initial position can be achieved by a telescopic mechanism located below the lower barrel, or by a position sensor located at the initial position of the lower barrel.

[0209] In some optional implementations, the method further includes:

[0210] Based on multiple values ​​of the second parameter, any number of pressure change rates at fixed time intervals are obtained;

[0211] If the difference between any two pressure change rates in an adjacent time interval among the plurality of pressure change rates is greater than a second preset pressure change value, the first barrel 101 will return to its initial position in the first direction X, which is a sealed state.

[0212] In this embodiment, multiple pressure change rates are obtained by acquiring multiple second parameter values. When the difference between any two pressure change rates in adjacent time intervals is greater than a second preset pressure change value, the first barrel 101 returns to its initial position in the first direction X, which is a sealed state. This setting can prevent the lower barrel of the slurry container 110 from settling during the mixing and pulping process, while ensuring the airtightness of the slurry container 110.

[0213] In some alternative embodiments, to prevent settling of the lower tank of the slurry container 110 while ensuring the airtightness of the slurry container 110, the method further includes:

[0214] When the stirring assembly 111 in the slurry production equipment 100 is in operation, the first tank 101 is periodically returned to its initial position in the first direction X, which is a sealed state.
