[0002] During battery production, abnormal conditions in raw materials or manufacturing processes may lead to the generation of non-standard slurries, such as low-viscosity slurries, slurries with abnormal solid content, and material leakage from the equipment.

[0003] However, the relevant technologies usually rely on manual operation by operators for recycling, and the recycled slurry is then manually put back into the production line, which is time-consuming and labor-intensive. Utility Model Content

Since the controller can control the opening and closing of the stirring component and the valve control, the above-mentioned automated design of slurry recycling and reuse can be realized, which is conducive to improving operating efficiency and reducing labor costs.

[0007] In some embodiments, the number of feed pipes is at least two, each feed pipe communicating with a feed inlet; and / or, the number of discharge pipes is at least two, each discharge pipe communicating with a discharge outlet.

It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0046] In this application, "multiple" means two or more (including two).

[0047] Currently, judging from market trends, the application of battery devices is becoming increasingly widespread. Battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery device applications, market demand is also constantly increasing.

[0048] In the production process of battery devices, the slurry is formed in the mixing process and then coated in the coating process. During the preparation of the electrode sheet, a coating device can be used to coat the slurry onto the current collector of the electrode sheet to form a coating layer.

[0049] During battery production, abnormal conditions in raw materials or manufacturing processes may lead to the generation of non-standard slurries, such as low-viscosity slurries, slurries with abnormal solid content, and material leakage from the equipment. These slurries can be recycled and processed before they can be reused to reduce costs.

[0050] However, the relevant technologies usually rely on manual operation by operators for recycling, and the recycled slurry is then manually fed back into the production line, which is a cumbersome process.

[0051] To address the aforementioned technical problems, this application provides a slurry processing apparatus, including a recovery mechanism, a connecting pipe assembly, valve controls, and a controller. The recovery mechanism includes a mixing tank with a receiving cavity and an inlet and an outlet respectively connected to the receiving cavity. A mixing assembly is provided within the receiving cavity, configured to mix the slurry within the receiving cavity. The connecting pipe assembly is connected to the recovery mechanism and includes an inlet pipe and an outlet pipe, the inlet pipe connected to the inlet and the outlet pipe connected to the outlet. The controls include a first valve and a second valve. The first valve is located on the inlet pipe and configured to control the opening and closing of the inlet pipe, and the second valve is located on the outlet pipe and configured to control the opening and closing of the outlet pipe. The controller is electrically connected to both the mixing assembly and the valve controls, and is configured to control the opening and closing of both the mixing assembly and the valve controls.

[0052] In the above technical solution, the slurry in the production equipment that needs to be recycled can enter the receiving cavity of the recycling mechanism through the feed pipe. The stirring component can stir the slurry in the receiving cavity to meet the production requirements. The slurry in the receiving cavity that meets the production requirements can enter the device in the production equipment through the discharge pipe for secondary use. Since the controller can control the opening and closing of the stirring component and valve control, the above-mentioned automated design of slurry recycling and reuse can be realized, which is conducive to improving operating efficiency and reducing labor costs.

[0053] The technical solutions described in this application can be used in conjunction with any device in a production facility that uses slurry, such as a mixing device, a coating device, a drying device, a transfer device, and a buffer device.

[0054] Please refer to the following: Figures 1 to 5According to an embodiment of this application, a slurry processing device 100 is provided, including a recovery mechanism 10, a connecting pipe assembly, a valve control, and a controller. The recovery mechanism 10 includes a mixing tank 11, which has a receiving cavity 111 and an inlet 112 and an outlet 113 respectively communicating with the receiving cavity 111. A mixing assembly 101 is provided within the receiving cavity 111, configured to mix the slurry within the receiving cavity 111. The connecting pipe assembly is connected to the recovery mechanism 10 and includes an inlet pipe 21 and an outlet pipe 22. The inlet pipe 21 communicates with the inlet 112, and the outlet pipe 22 communicates with the outlet 113. The valve control includes a first valve and a second valve. The first valve is disposed on the inlet pipe 21 and configured to control the opening and closing of the inlet pipe 21, and the second valve is disposed on the outlet pipe 22 and configured to control the opening and closing of the outlet pipe 22. The controller is electrically connected to the stirring assembly 101 and the valve control respectively, and the controller is configured to control the opening and closing of the stirring assembly 101 and the valve control.

[0055] The recycling mechanism 10 is used to recover slurry that needs to be recycled from the production equipment and allow it to re-enter the production equipment for reuse. The recycling mechanism 10 not only collects the slurry but also agitates it to achieve a certain viscosity, thus meeting the requirements for reuse.

[0056] The container 111 in the mixing tank 11 is used to hold the recycled slurry, and the mixing component 101 is used to mix the slurry in the container 111 to make the concentration of the slurry uniform and have a preset viscosity, so as to facilitate subsequent secondary use.

[0057] The feed inlet 112 can be located in the middle or at the top of the mixing tank 11, and the discharge outlet 113 can be located at the bottom of the mixing tank 11.

[0058] The mixing tank 11 can have the same structure as the mixing device 200 in the production equipment, and can have the same slurry storage environment as the mixing device 200. In addition to supporting the function of mixing slurry, it can also support functions such as vacuuming.

[0059] The valve control is connected to the connecting pipe assembly. The first valve is used to control the opening and closing of the feed pipe 21, which can be understood as the first valve being able to control whether there is slurry flowing in the feed pipe 21. The second valve is used to control the opening and closing of the discharge pipe 22, which can be understood as the second valve being able to control whether there is slurry flowing in the discharge pipe 22.

[0060] Specifically, the slurry in one or more devices in the production equipment can enter the receiving cavity 111 in sequence through the feed pipe 21 and the feed port 112. After being stirred by the stirring assembly 101, the slurry in the receiving cavity 111 can enter one or more devices in the production equipment in sequence through the discharge port 113 and the discharge pipe 22 for secondary use.

[0061] The recycling mechanism can be connected to at least one of the following in the production equipment: the stirring device 200, the coating device 300, the transfer device 500, and the buffer device, via a connecting pipe assembly.

[0062] It is understandable that during the operation of production equipment, some devices may have incorrect material feeding, or the slurry may not have entered the next process normally. There may also be cases where the slurry performance (viscosity, particle size, uniformity, etc.) is unqualified. The slurry processing device 100 can recycle such slurry and make it reusable to meet production needs, which helps to save costs.

[0063] "Electrical connection" means that there is a smooth flow of current between the controller and the stirring assembly 101 and the valve control, so that the controller can control the opening and closing of the stirring assembly 101 and the valve control.

[0064] The controller can start the mixing component 101 to agitate the slurry and adjust its viscosity. The controller can not only control the starting and stopping of the mixing component 101, but also adjust parameters such as the mixing time and speed.

[0065] The controller can control the opening and closing of the valve control to control the on / off of the feed pipe 21 and the discharge pipe 22, so that the slurry can enter or exit the receiving chamber 111. When there is a need for recycling, the first valve is activated to allow the slurry to enter the feed pipe 21, and the first valve is closed when there is no need for recycling. When there is a need for remixing, the first valve is activated to allow the slurry to enter the discharge pipe 22, and the first valve is closed when there is no need for remixing.

[0066] Among them, the need for remixing refers to the requirement that the equipment in the production facility needs to reuse the slurry recovered in the slurry processing device 100 to mix with its own slurry in order to save costs.

[0067] In practical applications, the first driving element 31 and the second driving element 32 can be opened and closed alternately, that is, when one of the first driving element 31 and the second driving element 32 is activated, the other is closed. Of course, the first driving element 31 and the second driving element 32 can also be set to open and close simultaneously. Correspondingly, the first valve and the second valve can be opened and closed alternately, that is, when one of the first valve and the second valve is activated, the other is closed. Of course, the first valve and the second valve can also be set to open and close simultaneously.

[0068] The slurry processing apparatus 100 provided in some embodiments of this application is used to recover slurry that needs to be recovered from production equipment and to stir the recovered slurry into slurry that can be returned to the production equipment for reuse. The slurry that needs to be recovered from the production equipment can enter the receiving cavity 111 of the recovery mechanism 10 through the feed pipe 21. The stirring component 101 can stir the slurry in the receiving cavity 111 to meet the production requirements. The slurry in the receiving cavity 111 that meets the production requirements can enter the device in the production equipment through the discharge pipe 22 for reuse. Since the controller can control the opening and closing of the stirring component 101 and the valve control, the above-mentioned automated design of slurry recovery and recycling can be realized, which is beneficial to improve the operation efficiency of slurry remixing and reduce labor costs.

[0069] Optionally, the stirring assembly 101 may be partially disposed within the receiving cavity 111, or it may be entirely disposed within the receiving cavity 111.

[0070] Optionally, the stirring assembly 101 may include a stirring paddle disposed at the center of the receiving cavity 111, and may also include a dispersing paddle disposed around the stirring paddle.

[0071] Both the feed pipe 21 and the discharge pipe 22 can be made into flexible hoses or rigid pipes.

[0072] Optionally, the first valve and the second valve may be, but are not limited to, ball valves, butterfly valves, gate valves, etc.

[0073] Optionally, the first valve can also be configured to regulate the flow rate or velocity of the slurry in the feed pipe 21; the second valve can also be configured to regulate the flow rate or velocity of the slurry in the discharge pipe 22.

[0074] The controller is located outside the tank. The controller may be any of the following: a microcontroller, a PLC control device, or a computer. Its specific control over each component may be performed according to a pre-set or edited program, or according to the input instructions of the operator.

[0075] Optionally, the controller can also control the state inside the receiving cavity 111, for example, it can control the receiving cavity 111 to be in a vacuum state.

[0076] In some embodiments, the number of feed pipes 21 can be set to one, or the feed pipe 21 can only be provided with one slurry inlet. That is, the receiving cavity 111 can only be connected to one of the devices in battery production. This device can be one of the stirring device 200, coating device 300, transfer device 500 and buffer device, so that the slurry that does not meet the standards or does not normally enter the next process in the device can enter the stirring tank 11 and wait for reuse, thereby avoiding the waste of slurry and helping to reduce costs.

[0077] In some embodiments, the number of feed pipes 21 can be two or more, or the feed pipes 21 can be provided with two or more slurry inlets. That is, the receiving cavity 111 can be connected to at least two devices in battery production. These devices can be at least two of the following: stirring device 200, coating device 300, transfer device 500, and buffer device, so that slurry that does not meet the standards or does not normally enter the next process in the device can enter the stirring tank 11.

[0078] In some embodiments, the number of discharge pipes 22 may be one, or the discharge pipe 22 may only have one slurry outlet. That is, the receiving cavity 111 may only be connected to one of the devices in battery production. This device may be one of the stirring device 200, the coating device 300, the transfer device 500, and the buffer device, so that the slurry that meets the standards in the receiving cavity 111 of the recycling mechanism 10 can be reused by entering one of the devices again.

[0079] In some embodiments, the number of discharge pipes 22 can be two or more, or the discharge pipes 22 can be provided with two or more slurry outlets. That is, the receiving cavity 111 can be connected to at least two devices in battery production. These devices can be at least two of the following: stirring device 200, coating device 300, transfer device 500, and buffer device, so that the slurry that meets the standards in the receiving cavity 111 of the recycling mechanism 10 can be reused by re-entering at least two devices.

[0080] Optionally, the slurry can be driven by a pump or gas pressure to transport it between devices requiring slurry recovery, devices requiring slurry remixing, and the recovery mechanism 10 within the production equipment. Optionally, the slurry can also be transported by gravity.

[0081] like Figure 1 As shown, in some alternative embodiments, the number of feed pipes 21 is at least two, and each feed pipe 21 is connected to the feed port 112.

[0082] The number of feed pipes 21 can be two, three, or even more. As an example, the number of feed pipes 21 can be the same as the number of devices using slurry in the production line, so that the slurry processing device 100 can recover all slurry in the production equipment that does not meet the standards or does not normally enter the next process, avoiding slurry waste and saving costs.

[0083] like Figure 2 As shown, in some alternative embodiments, the number of discharge pipes 22 is at least two, and each discharge pipe 22 is connected to the discharge port 113.

[0084] The number of discharge pipes 22 can be two, three, or even more. As an example, the number of discharge pipes 22 can be the same as the number of devices that use slurry in the production line, so that the slurry in the slurry processing device 100 can be re-input into at least one device in the production equipment for reuse as needed, which helps to improve the flexibility and versatility of the slurry processing device 100.

[0085] The slurry processing apparatus 100 provided in some embodiments of this application is configured in the manner described above so that the recycling mechanism 10 can be connected to at least two devices in the production equipment that have the need to recycle slurry, thereby improving the flexibility of use of the slurry processing apparatus 100.

[0086] Optionally, the number of feed pipes 21 and discharge pipes 22 is set to at least two, each feed pipe 21 is connected to the feed port 112, and each discharge pipe 22 is connected to the discharge port 113.

[0087] In some embodiments, the slurry processing apparatus 100 further includes a drive assembly, which includes a first drive member 31 and a second drive member 32. The first drive member 31 is disposed in the feed pipe 21 and configured to provide power for the slurry to enter the receiving cavity 111. The second drive member 32 is disposed in the discharge pipe 22 and configured to provide power for the slurry to be discharged from the receiving cavity 111. The controller is also electrically connected to the drive assembly and configured to control the opening and closing of the drive assembly.

[0088] The first driving member 31 can drive the slurry to flow from the feed pipe 21 to the receiving cavity 111, and the second driving member 32 can drive the slurry to flow from the receiving cavity 111 to the discharge pipe 22.

[0089] The controller can control the opening and closing of the drive components. When there is a need for recycling, the first drive component 31 is started to pump the slurry, and when there is no need for recycling, the first drive component 31 is turned off. When there is a need for remixing, the second drive component 32 is started to pump the slurry, and when there is no need for remixing, the second drive component 32 is turned off.

[0090] In the above technical solution, the slurry in the production equipment that needs to be recycled can be driven by the first driving member 31 to enter the receiving cavity 111 of the recycling mechanism through the feed pipe 21. The slurry in the receiving cavity 111 that meets the production requirements can be driven by the second driving member 32 to enter the device in the production equipment through the discharge pipe 22, which is beneficial to improving the operating efficiency of the slurry processing device 100.

[0091] Optionally, both the first drive member 31 and the second drive member 32 may include a pump body.

[0092] The first driving component 31 can be disposed on the side of the feed pipe 21 facing the mixing tank 11, or it can be disposed on the side of the feed pipe 21 away from the mixing tank 11. The second driving component 32 can be disposed on the side of the discharge pipe 22 facing the mixing tank 11, or it can be disposed on the side of the discharge pipe 22 away from the mixing tank 11.

[0093] Please see Figure 2 and Figure 3 In some optional embodiments, the slurry processing apparatus 100 further includes an adapter 40 having a main interface 41 and at least two sub-interfaces 42. The feed pipe 21 is provided with the adapter 40, and the feed pipe 21 has a main inlet pipe 211 and at least two sub-inlet pipes 212.

The at least two filters 12 can be connected by a pipeline, and the slurry in the mixing tank 11 can be filtered sequentially by the two filters 12 before entering the production equipment for secondary use, so as to further improve the cleanliness of the slurry and improve the reliability of the slurry processing device 100.

[0120] In some embodiments, the number of mixing tanks 11 is set to at least two, and the number of filters 12 is set to at least two.

[0122] As an example, a recycling facility 10 may include at least two mixing tanks 11 and at least two filters 12, which are connected in series according to certain rules.

[0124] Please continue reading. Figures 3 to 5 In some optional embodiments, the slurry processing apparatus 100 further includes a viscosity detection component 50, which is disposed in the receiving cavity 111 and configured to detect the viscosity of the slurry in the receiving cavity 111. The viscosity detection component 50 is communicatively connected to a controller.

[0125] The viscosity detection component 50 is used to detect the viscosity of the slurry in the receiving cavity 111 and can feed back the real-time viscosity value of the slurry in the receiving cavity 111 to the controller. The controller determines whether the viscosity of the slurry in the receiving cavity 111 meets the viscosity requirements based on the obtained real-time viscosity value. If the requirements are met, the stirring component 101 is controlled to stop stirring. If the requirements are not met, it is controlled to continue stirring. The viscosity detection component 50 continuously sends the real-time viscosity value of the slurry in the receiving cavity 111 to the controller until the detected real-time viscosity value meets the viscosity requirements.

[0126] Specifically, after the stirring assembly 101 has been running for a predetermined time, the controller can control the viscosity detection assembly 50 to automatically start detecting the viscosity of the slurry.

[0127] The slurry processing apparatus 100 provided in some embodiments of this application can automatically detect the viscosity of the recycled slurry in real time through the viscosity detection component 50, and the detection data can also be synchronously fed back to the controller. This allows for real-time monitoring and adjustment of the viscosity of the slurry in the receiving cavity 111, preventing the slurry from not meeting the viscosity requirements. This avoids the phenomenon that the viscosity of the slurry returned to the production line for reuse does not meet the production requirements, thus preventing slurry waste and improving the accuracy of slurry remixing. Furthermore, the detection process does not require manual sampling and testing, which helps reduce labor costs and improves the operational efficiency of slurry remixing.

[0128] In some embodiments, the viscosity detection component 50 may also be disposed outside the receiving cavity 111 and connected to the receiving cavity 111 via a pipe.

[0129] In some embodiments, the viscosity detection component 50 can be connected to the controller via a data cable.

[0130] In other embodiments, a wireless transmission module is provided in the viscosity detection component 50, and a wireless receiving module is provided in the controller, so that the real-time viscosity value information of the slurry can be transmitted to the controller wirelessly.

[0131] Optionally, the first drive member 31 and the second drive member 32 can be opened and closed alternately, and the first valve and the second valve can be opened and closed alternately, so as to ensure that the viscosity detection component 50 has sufficient time to detect the viscosity of the slurry in the receiving cavity 111, so as to ensure the accuracy of the detection results.

[0132] In some alternative embodiments, the mixing tank 11 also has a feeding port communicating with the receiving cavity 111.

[0133] The viscosity of the slurry can be detected by the viscosity detection component 50, so that the corresponding material can be added into the receiving cavity 111 through the feeding port.

[0134] For example, when the viscosity detection component 50 detects that the viscosity of the slurry is too low, powder can be added into the receiving cavity 111 through the feeding port; when the viscosity detection component 50 detects that the viscosity of the slurry is too high, solvent can be added into the receiving cavity 111 through the feeding port.

[0135] By setting it up in the above manner, it can be ensured that the performance of the recycled slurry in the receiving cavity 111 meets the requirements for remixing.

[0136] In some alternative embodiments, the slurry processing apparatus 100 further includes a quality detector 60 disposed on the discharge pipe 22 and configured to detect the mass of slurry passing through the discharge pipe 22 per unit time. The quality detector 60 is communicatively connected to a controller.

[0137] The quality detector 60 is used to measure the quality of the slurry, that is, the quality of the slurry passing through the discharge pipe 22 within a unit, so as to improve the accuracy of the ratio of the amount of newly added slurry in the production equipment and the amount of slurry remixed by the slurry treatment device 100.

[0138] In actual operation, when the quality detector 60 detects that the slurry flowing out of the discharge pipe 22 has reached the preset quality value, the quality detector 60 sends a signal to the controller, and the controller controls the second valve to close, that is, controls the discharge pipe 22 to disconnect, so that the slurry processing device 100 can realize the automatic shut-off operation of feeding.

[0139] Since the ratio of recycled slurry to normal slurry must be strictly controlled during use, the above method can achieve precise feeding.

[0140] The slurry processing apparatus 100 provided in some embodiments of this application uses a quality detector 60 to detect the quality of slurry passing through the discharge pipe 22 within a unit time, so as to control the opening and closing of the discharge pipe 22 as needed, so that the slurry processing apparatus 100 can feed the preset quality of slurry into the production line, thereby improving the accuracy of the slurry processing apparatus 100.

[0141] In some embodiments, the quality detector 60 can be connected to the controller via a data cable.

[0142] In other embodiments, a wireless transmitting module is provided in the quality detector 60 and a wireless receiving module is provided in the controller, so that the quality of the slurry in the discharge pipe 22 can be transmitted to the controller wirelessly.

[0143] Please continue reading. Figures 3 to 5 In some optional embodiments, the slurry processing apparatus 100 further includes a parameter detection component 70, which is disposed in the receiving cavity 111 and configured to detect parameter information of the slurry in the receiving cavity 111. The parameter information includes at least one of mass, type, temperature and humidity. The parameter detection component 70 is communicatively connected to the controller.

[0144] The parameter detection component 70 can detect the parameter information of the slurry in the receiving cavity 111 and transmit the parameter information to the controller. The controller can record the parameter information of the slurry and control the opening and closing of the corresponding components.

[0145] The parameter detection component 70 can detect the type of slurry in the receiving cavity 111 and send this information to the controller. The controller can determine whether the type of slurry in the receiving cavity 111 is consistent with the type of slurry added to the device with the need for remixing in the production equipment downstream of the slurry processing device 100, so as to prevent the wrong material from being added during the remixing process and realize the function of verifying the type of slurry. When the two are consistent, the controller controls the second valve to open so that the discharge pipe 22 is open. When they are inconsistent, the controller alarms and controls the second valve to close so that the discharge pipe 22 is disconnected. The slurry processing device 100 needs to be unlocked afterward before it can continue to operate.

[0146] The parameter detection component 70 can detect the quality information of the slurry in the receiving cavity 111. When the slurry processing device 100 has a need for remixing, that is, when the slurry recovered in the slurry processing device 100 needs to be reused, the controller can automatically set the remixing ratio and automatically calculate the remixing amount according to the feeding amount of the device with the remixing requirement, and control the second valve to open so that the discharge pipe 22 can be opened to remix the slurry back into the production line, thereby improving the accuracy of the slurry remixing ratio and thus improving the reliability of the slurry processing device 100.

[0147] The parameter detection component 70 can detect parameters such as temperature and humidity of the slurry in the receiving cavity 111. The controller can adjust the temperature and humidity of the slurry in the receiving cavity 111 based on the parameter information fed back by the parameter detection component 70.

[0148] Some of the slurry processing devices 100 provided in this application embodiment can send parameter information and some performance data of the recycled slurry to the controller and upload them to the database for storage, which is beneficial to improving the automation design of the slurry processing device 100.

[0149] In some embodiments, the parameter detection component 70 can be connected to the controller via a data cable.

[0150] In other embodiments, a wireless transmission module is provided in the parameter detection component 70, and a wireless receiving module is provided in the controller, so that the information of the slurry in the receiving cavity 111 can be transmitted to the controller wirelessly.
