Description

Technical Field

[0001] The present invention relates to the technical field of battery slurry mixing, and in particular to a battery slurry mixing device. Background Art

[0002] In the manufacturing process of lithium-ion batteries, the uniformity and stability of battery slurry are one of the core factors affecting electrode performance. Battery slurry is usually composed of active materials, conductive agents, binders and solvents. The mixing process must ensure that each component is fully dispersed and forms a stable suspension system. At present, the industry generally adopts a process flow of multi-batch mixing tanks combined with transfer tank homogenization: first, the slurry is mixed and dispersed in a high-speed dispersion mixing tank, and then the slurry produced by multiple batches of mixing tanks is transferred to the transfer tank. The continuous low-speed stirring of the transfer tank further eliminates the parameter differences between different mixing tank batches (such as viscosity, solid content, particle dispersion, etc.), and finally obtains a slurry that meets the consistency requirements.

[0003] However, the existing transfer tank has significant technical bottlenecks in actual operation. When the slurry mixed in the stirring tank is pumped to the transfer tank, since the feed port is usually located at the top of the tank body, the newly added slurry will accumulate in the upper area of the transfer tank. Although the transfer tank is equipped with a low-speed anti-settling stirring component (such as an anchor or paddle stirrer), its original design intention is to avoid high shear force from destroying the slurry structure (such as conductive agent fiber breakage or secondary agglomeration of active materials), resulting in a strict limit on the stirring speed (usually less than 30rpm). Under this condition, laminar mixing of the slurry in the tank dominates, and it is difficult for the newly added top slurry to quickly form convection diffusion with the original slurry in the tank, and the mixing efficiency is significantly reduced. Experimental data show that the homogenization time of the slurry in the transfer tank can reach 2-4 hours, and the greater the height of the tank body, the more obvious the gradient of the slurry parameters in the upper and lower layers. This defect causes the slurry output from multiple batches of stirring tanks to be unable to be fully homogenized in the transfer tank in a short period of time, which ultimately causes increased surface density fluctuations during electrode coating, directly affecting the battery capacity consistency and cycle life.

[0004] Existing improvement plans often focus on optimizing the process parameters of the mixing tank (such as dispersion time and rotation speed) or adding auxiliary mixing structures (such as guide baffles) to the transfer tank. However, the former is difficult to completely eliminate batch-to-batch variability, while the latter increases slurry flow resistance and causes localized sedimentation risk. Therefore, there is an urgent need for a battery slurry mixing device that can achieve rapid layered mixing and homogenization of the slurry through structural innovation without introducing high shear forces, thereby overcoming the limitations of existing processes. Summary of the Invention

[0005] In order to solve the above problems, an embodiment of the present invention provides a battery slurry mixing device, which achieves the purpose of solving the problems raised in the background technology.

[0006] To achieve the above-mentioned objectives, the embodiments of the present invention specifically adopt the following technical solutions: A battery slurry mixing device, comprising: a transfer tank for receiving the battery slurry after stirring and mixing; a material injection mechanism provided on the transfer tank for conveying the stirred and mixed battery slurry into the interior of the transfer tank; a mixing mechanism, which is in communication with the material injection mechanism and is provided on the transfer tank for preventing the battery slurry from settling inside the transfer tank; wherein the mixing mechanism is designed so that when the mixing mechanism is in operation, the battery slurry conveyed by the material injection mechanism can be evenly added to the interior of the transfer tank;

[0007] The battery slurry mixed and dispersed in the stirring tank is evenly added to the interior of the transfer tank through the cooperation of the mixing mechanism and the injection mechanism, thereby reducing the time required for the transfer tank to be fully homogenized.

[0008] In order to homogenize the battery slurry inside the transfer tank and prevent the battery slurry inside the transfer tank from settling, the present application proposes a mixing mechanism, which includes: a stirring frame, a driving assembly, and a stirring frame for driving the stirring frame to rotate and revolve simultaneously;

[0009] The driving assembly drives the stirring frame to stir and mix inside the transfer tank, so that the battery slurry inside the transfer tank is homogenized and the battery slurry inside the transfer tank is prevented from settling.

[0010] In order to achieve the purpose of injecting battery slurry into the interior of the transfer tank through a mixing mechanism, the present application proposes a stirring frame, the interior of which is provided with a channel connected to the injection mechanism, and the stirring frame is also provided with multiple discharge holes connected to the channel.

[0011] In order to achieve the purpose of the mixing mechanism uniformly adding the battery slurry into the transfer tank, the mixing mechanism further includes: an adjusting component for adjusting the pressure inside the channel to adjust the communication state between the discharge hole and the channel.

[0012] The adjustment component includes: a chute, which is opened inside the stirring frame and is connected with the channel and the discharge hole respectively; a slider, which has a through hole opened inside and is slidably arranged inside the chute, and the connection state between the through hole and the discharge hole is adjusted by changing the position of the slider inside the chute; a spring, which is arranged inside the chute to provide elastic force to the slider; the position of the slider inside the chute is changed by changing the pressure inside the channel, so that the through hole is aligned with the discharge holes at different heights, so that the battery slurry enters the interior of the transfer tank from different height areas.

[0013] In order to further achieve the above purpose, two adjusting components are provided, and the two adjusting components are arranged in a circular array inside the stirring frame. The two through holes can be aligned with the discharge holes at different heights through the two adjusting components.

[0014] In order to achieve the purpose of delivering the battery slurry mixed and dispersed inside the stirring tank to the mixing mechanism, the present application proposes a feeding mechanism, which includes: a feeding pipe, a filtering assembly arranged on the stirring frame for filtering the battery slurry, and a connecting pipe for connecting the feeding pipe and the filtering assembly;

[0015] The discharge pipe is connected to the stirring tank, and the battery slurry inside the stirring tank enters the interior of the connecting pipe through the discharge pipe, and then enters the channel after being filtered by the filtering component.

[0016] In order to achieve the purpose of filtering the battery slurry entering the channel through the filter assembly, the present application proposes a filter assembly, which includes: a base, which is configured as a hollow structure, the interior of which is respectively connected to the connecting pipe and the channel and is rotatably connected to the connecting pipe; a filter screen, which is arranged inside the base and is used to filter the battery slurry passing through; a scraper, which is fixedly connected to the end of the connecting pipe and is used to scrape and clean the upper surface of the filter screen; and a drain hole, which is opened on the side of the base and is used to discharge debris scraped and cleaned by the scraper on the filter screen;

[0017] The battery slurry is filtered through the filter and then enters the channel. The scraper can scrape off the debris screened out of the filter, and the screened debris can be discharged after the drain hole is opened.

[0018] In order to achieve the purpose of driving the stirring frame to rotate and revolve simultaneously through a driving assembly, the present application proposes a driving assembly, which includes: a top cover, which is arranged at the top opening of the transfer tank, a rotating plate, which is rotatably arranged inside the top cover, the stirring frame is rotatably arranged on the rotating plate, a gear ring, which is fixedly connected to the inside of the top cover, a gear 1, which is fixedly connected to the outside of the stirring frame and meshes with the gear ring, a gear 2, which is fixedly connected to the rotating plate, a gear 3, which meshes with the gear 2, and a motor, which is arranged on the top cover and is used to drive the gear 3 to rotate;

[0019] Driven by the motor, the power is transmitted to the rotating plate through the transmission mechanism composed of gear 2 and gear 3 in sequence, driving the stirring frame to perform circular motion (revolution) around the axis of the transfer tank; while the stirring frame rotating on the rotating plate moves along the orbit, a planetary gear transmission relationship is formed through the meshing action of gear 1 and the gear ring, so that the stirring frame generates self-rotation motion during the revolution, and finally realizes a rotation mode combined with revolution and rotation.

[0020] The beneficial effects of the embodiments of the present invention are:

[0021] A battery slurry mixing device includes a transfer tank connected to a stirring tank. A mixing mechanism is provided inside the transfer tank to prevent the battery slurry from settling. A feeding mechanism transfers the battery slurry in the stirring tank to the mixing mechanism. During operation, the mixing mechanism can evenly add the battery slurry to the transfer tank. By providing the mixing mechanism, rapid layered mixing and homogenization of the slurry can be achieved through structural innovation without introducing high shear forces.

[0022] Since the stirring frame rotates in a complex trajectory, it discharges the battery slurry into the transfer tank during the rotation process, so that the battery slurry enters the transfer tank more dispersedly. This dispersed addition method helps the battery slurry to be evenly distributed in the transfer tank, thereby achieving uniform mixing of the battery slurry;

[0023] In this application, the internal pressure of the channel is adjusted to control the battery slurry from entering different height areas inside the transfer tank. At the same time, the complex rotation of the stirring frame is used to evenly distribute the battery slurry inside the transfer tank. The dual effects of the pressure regulation inside the channel and the complex rotation of the stirring frame ensure the uniformity and mixing effect of the battery slurry entering the transfer tank, thereby facilitating the homogenization of the battery slurry inside the transfer tank.

[0024] When the battery slurry falls onto the filter through the connecting pipe, the filter's rotation generates centrifugal force, evenly distributing the battery slurry across the filter surface for easier filtration. Furthermore, the filter's rotation is driven by the stirring frame, eliminating the need for an additional drive source and simplifying the structural design. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0037] See also Figure 1 The embodiment of the present invention discloses a battery slurry mixing device, including a transfer tank 1 connected to a stirring tank. A mixing mechanism 3 is provided inside the transfer tank 1 to prevent the battery slurry from settling. The injection mechanism 2 transfers the battery slurry in the stirring tank to the mixing mechanism 3. During operation, the mixing mechanism 3 can evenly add the battery slurry to the interior of the transfer tank 1. By providing the mixing mechanism 3, without introducing high shear force, structural innovation is utilized to achieve rapid layered mixing and homogenization of the slurry.

[0038] A discharge pipe is provided at the bottom of the transfer tank 1 so that the battery slurry inside the transfer tank 1 can be discharged through the discharge pipe.

[0039] See also Figure 1 , which shows an embodiment of the mixing mechanism 3 proposed in the present application. Specifically, a stirring frame 31 is provided inside the transfer tank 1. The stirring frame 31 is driven by a driving assembly 32 to simultaneously perform revolution and rotation, forming a complex rotation trajectory. This motion mode helps the stirring frame 31 to fully mix the battery slurry.

[0040] When the battery slurry is added to the interior of the transfer tank 1, the injection mechanism 2 transports the battery slurry in the stirring tank to the channel 33 formed inside the stirring frame 31. The battery slurry is then discharged through a plurality of discharge holes 34 connected to the channel 33 and enters the interior of the transfer tank 1.

[0041] Since the stirring frame 31 rotates in a complex trajectory, it discharges the battery slurry into the transfer tank 1 during the rotation process, so that the battery slurry enters the transfer tank 1 more dispersedly. This dispersed addition method helps the battery slurry to be evenly distributed in the transfer tank 1, thereby achieving uniform mixing of the battery slurry.

[0042] See also Figure 1 、 4The cam 352 is provided with a spring 354 which is arranged on the top of the mixing frame 31 so as to allow the battery slurry to be added to the interior of the transfer tank 1 more evenly.

[0043] The battery slurry can be added more evenly into the interior of the transfer tank 1 by adjusting the component 35, which is specifically as follows:

[0044] When the pressure inside the channel 33 is low, the pressure on the slider 352 is small, and the spring 354 is not compressed. At this time, the through hole 353 is aligned with the discharge hole 34 at a certain height. At this time, the battery slurry can be discharged into the area of the transfer tank 1 at this level through the discharge hole 34;

[0045] When the pressure inside the channel 33 is high, the slider 352 is subjected to greater pressure. At this time, the spring 354 is compressed, causing the slider 352 to slide inside the chute 351. At this time, the through hole 353 is aligned with the discharge hole 34 at another level. At this time, the battery slurry can be discharged into the area of the transfer tank 1 at this level through the discharge hole 34.

[0046] In actual use, by adjusting the pressure change inside the channel 33, the battery slurry is driven from the discharge holes 34 at different levels into the different height areas of the transfer tank 1. This design helps the battery slurry to be fully dispersed and mixed inside the transfer tank 1, thereby achieving a more uniform mixing effect.

[0047] In order to allow the slider 352 to slide normally inside the slide groove 351, a pressure relief hole is opened at the end of the slide groove 351, so that when the slider 352 slides inside the slide groove 351, the battery slurry inside the slide groove 351 can be discharged through the pressure relief hole.

[0048] In actual use, a booster pump can be installed inside the injection mechanism 2 to regulate the pressure inside the channel 33, causing it to fluctuate regularly. This pressure change drives the slider 352 to slide within the channel 33, allowing the battery slurry to be discharged into the transfer tank 1 through the discharge holes 34 at different levels. This design helps to achieve uniform distribution and homogenization of the battery slurry within the transfer tank 1.

[0049] See also Figure 4 In order to further improve the uniform dispersion effect of the battery slurry inside the transfer tank 1, two adjustment components 35 are provided in the present application. The two adjustment components 35 are arranged in a circular array on the stirring frame 31, which are specifically:

[0050] After the two adjustment components 35 are arranged in a circular array on the stirring frame 31, the discharge holes 34 on the stirring frame 31 can be divided into upper discharge holes 34, middle discharge holes 34 and lower discharge holes 34 according to their distribution layer height. When the pressure inside the channel 33 is small, the pressure borne by the slider 352 is small. The two through holes 353 in the two adjustment components 35 are respectively aligned with the middle discharge holes 34 on the stirring frame 31. That is, at this time, the battery slurry enters the middle layer area of the transfer tank 1. After the battery slurry is discharged for a period of time, the pressure inside the channel 33 is increased. At this time, the pressure borne by the slider 352 is large, and the slider 352 inside one of the adjustment components 35 moves forward under the action of pressure. The slider 352 moves downward, and the spring 354 is compressed. At this time, the through hole 353 on the slider 352 is aligned with the lower discharge hole 34. The slider 352 inside the other adjusting component 35 moves upward under the action of pressure, and the spring 354 is compressed. At this time, the through hole 353 on the slider 352 is aligned with the upper discharge hole 34. At this time, the battery slurry can enter the upper and lower areas of the transfer tank 1; by adjusting the pressure change inside the channel 33, the battery slurry can enter the upper, middle and lower areas of the transfer tank 1 respectively. This regional feeding method helps the battery slurry to enter the transfer tank 1 evenly, thereby improving the mixing uniformity;

[0051] In this field, discharge holes 34 at different heights can be set on the stirring rack 31, so that the battery slurry can enter the upper area, middle area and lower area inside the transfer tank 1; but its mixing effect is poor, because the battery slurry continuously enters the interior of the transfer tank 1 through the discharge hole 34. Although the stirring rack 31 is rotating and stirring at the same time, the fluidity of the battery slurry is poor. The mixing of the battery slurry mainly depends on the stirring of the stirring rack 31. Continuous addition of battery slurry is prone to uneven mixing. In the present application, when the internal pressure of the channel 33 is relatively low, the battery slurry is discharged into the middle area of the transfer tank 1 through the middle discharge hole 34. At this time, the battery slurry is discharged through the stirring rack The rotation of 31 is used to mix the battery slurry in the middle area; when the internal pressure of the channel 33 is relatively high, the battery slurry is discharged into the upper and lower areas of the transfer tank 1 through the upper and lower discharge holes 34. At this time, the middle area of the transfer tank 1 is no longer added with battery slurry, and the stirring rack 31 continues to stir and mix the middle area to facilitate full mixing of the battery slurry in the middle area; then, when the pressure inside the channel 33 is reduced again, the battery slurry is discharged into the middle area of the transfer tank 1 through the middle discharge hole 34, but at this time, the upper and lower areas of the transfer tank 1 are no longer added with battery slurry, and the stirring rack 31 continues to stir and mix the upper and lower areas;

[0052] By providing the regulating assembly 35, the battery slurry can be intermittently added to the upper, middle, and lower regions of the transfer tank 1. This regional, intermittent feeding method helps the battery slurry to be fully mixed inside the transfer tank 1, thereby achieving a more uniform mixing effect;

[0053] In this application, the internal pressure of channel 33 is adjusted to control the flow of battery slurry into different height zones within transfer tank 1. Simultaneously, the complex rotation of stirring frame 31 ensures uniform distribution of the battery slurry within transfer tank 1. The dual effects of pressure regulation within channel 33 and the complex rotation of stirring frame 31 ensure uniform mixing of the battery slurry upon entry into transfer tank 1, thereby facilitating homogenization of the battery slurry within transfer tank 1.

[0054] See also Figure 1 、 3 5, which shows an embodiment of the injection mechanism 2 proposed in the present application, specifically, a filter assembly 22 is provided at the top of the stirring frame 31, and the filter assembly 22 is connected to the channel 33 inside the stirring frame 31. By providing a discharge pipe 21 connected to the stirring tank, the battery slurry inside the stirring tank is added to the interior of the filter assembly 22 through the discharge pipe 21 for filtration, and the filtered battery slurry enters the channel 33 inside the stirring frame 31;

[0055] In order to enable the stirring frame 31 to rotate and revolve normally, one end of the connecting pipe 23 is rotatably connected to the filter assembly 22, and the other end is rotatably connected to the discharge pipe 21, and the discharge pipe 21 is arranged along the axis of the transfer tank 1, that is, the discharge pipe 21 is located at the revolution axis position of the stirring frame 31. The discharge pipe 21 does not rotate or revolve, and the booster pump can be installed on the discharge pipe 21.

[0056] join Figure 5 , which shows an embodiment of the filter assembly 22 proposed in the present application. Specifically, a base 221 is fixedly connected to the top of the stirring frame 31, so that the base 221 can rotate with the rotation of the stirring frame 31. At the same time, a filter screen 222 is fixedly connected to the inside of the base 221. The battery slurry added to the inside of the base 221 can be filtered through the filter screen 222. The filter screen 222 can filter out larger agglomerates or other large-sized debris (particulate matter) in the battery slurry, thereby ensuring the quality of the battery slurry added to the transfer tank 1;

[0057] The diameter of the filter screen 222 is larger than that of the connecting tube 23. When the battery slurry passes through the connecting tube 23 and falls onto the filter screen 222, the rotation of the filter screen 222 generates centrifugal force, which evenly distributes the battery slurry on the surface of the filter screen 222, facilitating filtration. In addition, the rotation of the filter screen 222 is driven by the rotation of the stirring frame 31, eliminating the need for an additional drive source and simplifying the structural design.

[0058] A scraper 223 is provided at the bottom of the connecting pipe 23. The connecting pipe 23 is rotatably provided on the base 221. When the base 221 rotates, the connecting pipe 23 does not rotate, so that the scraper 223 and the filter 222 rotate relative to each other, so that the scraper 223 can scrape and clean the upper surface of the filter 222, thereby preventing a large amount of debris from accumulating on the filter 222 and affecting the filtering effect of the filter 222.

[0059] A drain hole 224 is provided on the side of the base 221. During normal use, the drain hole 224 is closed. When debris removed by the scraper 223 needs to be cleaned, the drain hole 224 is opened. The centrifugal force generated by the rotation of the filter 222 and the guiding action of the scraper 223 combine to allow debris to be smoothly discharged through the drain hole 224.

[0060] See also Figure 1-2, which shows an embodiment of the driving assembly 32 proposed in the present application, specifically, a top cover 321 is provided on the top of the transfer tank 1, and a gear ring 323 is fixedly connected to the inside of the top cover 321. The inside of the top cover 321 is also rotatably connected to the rotating plate 322, and the stirring frame 31 is eccentrically connected to the rotating plate 322. When the rotating plate 322 rotates, the stirring frame 31 revolves. While the stirring frame moves with the revolving orbit, the gear 1 324 fixedly connected to the stirring frame 31 engages with the gear ring 323, so that the stirring frame 31 generates self-rotation during the revolving process, thereby realizing a rotation mode in which the stirring frame 31 is driven by the driving assembly 32 to perform a combined revolving and self-rotating rotation.

[0061] Gear 2 325 is fixedly connected to the rotating plate 322, and a motor 327 is provided on the top cover 321. Gear 3 326 is fixedly connected to the output shaft of the motor 327. After the motor 327 is started, the gear 3 326 is driven to rotate, thereby driving the gear 2 325 to rotate, and thus driving the top cover 321 to rotate.
