Description

Technical Field

[0001] This invention relates to the field of lithium battery slurry technology, and more specifically, to a homogenizing device for positive and negative electrode slurries of lithium batteries. Background Technology

[0002] The lithium battery positive and negative electrode slurry homogenization equipment is the core equipment used to prepare electrode slurry in lithium battery production. Its core function is to uniformly disperse the positive or negative electrode slurry through a combination of stirring, dispersing, and mixing to form a stable, homogeneous slurry system with specific rheological properties. Ultimately, it provides electrode slurry that meets the process requirements for subsequent electrode coating, rolling and other processes, which directly affects the energy density, cycle life and safety performance of lithium batteries.

[0003] Currently, most mainstream homogenization equipment uses a dual planetary mixer, which breaks up material agglomerates by generating strong shear force, centrifugal force, and turbulence through the rotation of the impellers. Simultaneously, it achieves uniform mixing of the slurry system through a combination of revolution and rotation. After homogenization of the lithium battery slurry, the slurry in the reactor is usually discharged to a temporary storage tank for subsequent coating processes. However, the homogenized lithium battery slurry has high viscosity, and a thick layer of slurry easily adheres to the outer wall of the impeller and the inner wall of the reactor, forming a wall-mounted layer. In existing processes, the slurry in the reactor is mainly discharged through the bottom discharge channel by its own gravity. This method makes it difficult to fully collect the residual slurry adhering to the reactor wall and impeller sidewalls, ultimately requiring cleaning equipment for removal. This residue problem has persisted for a long time, resulting in a large amount of slurry waste. Therefore, we propose a homogenization device for lithium battery positive and negative electrode slurries. Summary of the Invention

[0009] Preferably, the inner cavity of the rotating cylinder is provided with a sliding groove, and the inner side wall of the sliding groove is provided with multiple insertion holes.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention designs two symmetrically arranged semi-circular cleaning plates. After the dual planetary mixer completes the mixing of the slurry, the two mixing rods are controlled by the dual planetary mixer to form a linearly aligned stationary state. Subsequently, the two semi-circular cleaning plates move towards each other in the horizontal direction, forming a combined state above the vessel body. The combined cleaning plates form a circular structure with the same shape as the inner cavity of the vessel. At the same time, the cleaning grooves of the two semi-circular cleaning plates merge to form a circular slot adapted to the structure of the mixing rod, forming a close-fitting and surrounding state on the outer circumference of the mixing rod. Then, the two combined semi-circular cleaning plates move vertically downward within the inner cavity of the vessel, utilizing the circular structure of the combined cleaning plates... The peripheral wall scrapes and cleans the slurry adhering to the inner wall of the vessel, and the cleaning groove scrapes and cleans the slurry adhering to the outer wall of the stirring rod. As the circular cleaning plate descends, it applies downward pressure to the slurry in the vessel cavity, causing the slurry to be discharged through the discharge pipe, so that the slurry does not rely on its own gravity for discharge. This achieves stable discharge and automatically cleans the slurry adhering to the inner wall of the vessel and the outer wall of the stirring rod during the discharge process. It solves the problem of conventional discharge methods that rely on the gravity of the fluid slurry for discharge, which is prone to incomplete discharge due to the high viscosity of the slurry and the large amount of residue adhering to the wall, ultimately requiring cleaning equipment and causing a large amount of slurry waste.

[0013] 2. This invention features multiple inclined grooves on the side wall of the drive plate and multiple horizontal and vertical grooves on the side wall of the guide plate, with the vertical grooves connected to the horizontal grooves. When the drive mechanism moves the moving frame and drive plate along the guide plate, the inclined structure of the inclined grooves generates a combined horizontal and vertical driving force on the drive column. First, the drive column slides smoothly in the horizontal groove, ensuring that the two semi-circular cleaning plates are precisely horizontally merged to fit and surround the stirring rod. When the drive column slides to the connection point between the horizontal and vertical grooves, the driving force of the inclined grooves switches to a predominantly vertical direction, guiding the drive column into the vertical groove for stable vertical sliding. This, in turn, causes the merged semi-circular cleaning plates to descend vertically along the inner cavity of the vessel. This achieves the conversion between the horizontal and vertical movement states of the semi-circular cleaning plates. Without complex mechanical equipment or power sources, the linear movement of the moving frame is driven by a single power source from the drive mechanism. By utilizing the structural cooperation of the inclined grooves, horizontal grooves, and vertical grooves, the horizontal power of the moving frame is converted into a continuous horizontal and vertical sliding motion of the drive column, thereby automating the merging and descent of the semi-circular cleaning plates.

[0014] 3. This invention achieves integrated mixing and cleaning functions by designing two tilt states for the mixing blades: a slightly horizontal and a slightly vertical tilt. Combined with its adaptable structure to the vessel body and the semi-circular cleaning plate, this design allows for the seamless integration of mixing and cleaning functions. During the homogenization stage, the mixing blades maintain a slightly horizontal tilt, forming a gap fit with the bottom of the vessel's inner cavity. As the rotating cylinder rotates, it thoroughly mixes the slurry at the bottom of the vessel, creating a three-dimensional mixing range with the stirring rod, preventing slurry sedimentation and ensuring uniform mixing. When the semi-circular cleaning plate descends vertically to its lower limit position and completes the connection between the vessel wall and the stirring rod... After the wall is cleaned, the cleaning blades switch to a slightly vertical tilt, with one side tightly against the bottom of the semi-circular cleaning plate and the other side against the bottom of the inner cavity of the vessel. When rotating under the drive of the rotating cylinder, it can efficiently scrape off the residual wall slurry at the bottom of the semi-circular cleaning plate, preventing this part of the slurry from being reset with the cleaning plate and causing secondary pollution or waste. At the same time, the large amount of slurry cleaned off is pushed to the discharge pipe by the centrifugal force generated by its rotation, further improving the slurry collection rate. This solves the problem that the semi-circular cleaning plate cannot handle the slurry accumulated at its bottom after cleaning the vessel wall and the stirring rod.

[0015] 4. This invention features a design where two mixing blades are coaxially connected to a rotating rod and a rotating sleeve, with symmetrical toothed halves. Two adjusting cylinders drive halves one and two to rotate, causing the rotating rod and rotating sleeve to rotate in opposite directions. This allows the two mixing blades to rotate coaxially and in opposite directions around the common axis of the rotating rod and rotating sleeve. It is important to note that if the mixing blades rotate in a complete circular path around this common axis, their trajectory will interfere with the top and bottom of the cleaning chamber. Therefore, the rotation range of the mixing blades is limited to a "slightly horizontal tilt" and a "slightly vertical tilt," rotating only along the switching path between these two states to avoid interference. The synchronous and opposite rotation of the two mixing blades ensures that each moves independently within its own state switching path without interfering with the other, satisfying the state switching requirements while avoiding motion interference.

[0016] 5. This invention, through the design of a locking structure for the regulating cylinder, ensures that during the homogenization stage, the insertion and locking of the rod and the insertion hole can stably fix the regulating cylinder at a specific height within the sliding groove. This ensures precise meshing between the toothed plate and the half-gear of the cleaning blade, allowing the cleaning blade to maintain a stable, slightly horizontal tilt. This avoids excessive lateral thrust on the cleaning blade due to the viscosity of the slurry during mixing, which could cause the cleaning blade to shift at an angle and affect the mixing effect. During the cleaning stage, pressing down the semi-circular cleaning plate triggers the regulating cylinder to unlock and move downward. The toothed plate then drives the cleaning blade to switch to a slightly vertical tilt to clean the slurry adhering to the wall. After cleaning, springs one and two automatically push the regulating cylinder and control plate back to reset, and the rod relocks the regulating cylinder. This structure effectively solves the problems of relying on complex external power and manual intervention for the switching of the cleaning blade state, as well as the low switching accuracy and poor stability.

[0017] 6. The present invention also designs the top of the drive head as a conical structure, so that the pressure of the slurry it receives can be evenly distributed along the conical surface, avoiding the pressure generated by the slurry from causing the drive head to move downward, ensuring that the drive head always maintains a stable position during the homogenization stage and does not trigger the unlocking action of the regulating cylinder, thereby ensuring that the cleaning blades continuously maintain a slightly horizontal tilted state to efficiently mix the slurry.

Detailed Implementation

[0020] Example 1, as Figures 1 to 16 As shown, this embodiment provides a homogenizing device for lithium battery positive and negative electrode slurries, including a device platform 1. A double planetary mixer 2 and a slurry cleaning component 3 are arranged on the top of the device platform 1. The double planetary mixer 2 includes multiple stirring rods 21 and a vessel body 22. The double planetary mixer 2 uses a conventional motor-driven planetary gear system to realize the revolution and rotation of the stirring rods 21. The stirring rods 21 are arranged in the inner cavity of the vessel body 22. The stirring rods 21 have a U-shaped rod structure, and the two stirring rods 21 can form a linear alignment state. The stirring rods 21 are used to stir the lithium battery slurry in the inner cavity of the vessel body 22. Multiple cleaning blades 23 are arranged at the bottom of the inner cavity of the vessel body 22. The cleaning blades 23 are arranged below the stirring rods 21. When the cleaning blades 23 rotate, they can stir the lithium battery slurry at the bottom of the inner cavity of the vessel body 22, forming a three-dimensional stirring range in conjunction with the stirring rods 21.

[0021] Furthermore, the slurry cleaning component 3 includes two symmetrically arranged semi-circular cleaning plates 31, with multiple cleaning grooves 3101 on the sidewalls of the semi-circular cleaning plates 31. The two semi-circular cleaning plates 31 can move towards each other in the horizontal direction to form a combined state above the vessel body 22. The cleaning grooves 3101 of the two semi-circular cleaning plates 31 in the combined state can form a close-fitting and surrounding state on the outer circumference of the stirring rod 21. The two semi-circular cleaning plates 31 in the combined state can also move vertically downward within the inner cavity of the vessel body 22 to clean the slurry adhering to the inner sidewall of the vessel body 22 and the outer circumference of the stirring rod 21. When the two semi-circular cleaning plates 31 in the combined state move vertically downward to the lower limit position in the inner cavity of the vessel body 22, the space between the bottom of the semi-circular cleaning plate 31 and the bottom of the inner cavity of the vessel body 22 forms a cleaning chamber 36; the cleaning blades 23 are movably arranged in the cleaning chamber 36; the side wall of the vessel body 22 is connected to a discharge pipe 2201, and the discharge pipe 2201 is in communication with the inner cavity of the cleaning chamber 36.

[0022] This invention designs two symmetrically arranged semi-circular cleaning plates 31. After the dual planetary mixer 2 completes the mixing of the slurry, the two mixing rods 21 are controlled by the dual planetary mixer 2 to form a linearly aligned stationary state. Subsequently, the two semi-circular cleaning plates 31 move towards each other in the horizontal direction, forming a combined state above the vessel body 22. The combined cleaning plates form a circular structure with the same shape as the inner cavity of the vessel body 22. At the same time, the cleaning grooves 3101 of the two semi-circular cleaning plates 31 merge to form a circular slot adapted to the structure of the mixing rod 21, forming a close-fitting and surrounding state on the outer circumference of the mixing rod 21. Then, the two semi-circular cleaning plates 31 in the combined state move vertically downward within the inner cavity of the vessel body 22, utilizing the cleaning effect of the combined circular structure. The cleaning plate scrapes and cleans the slurry adhering to the inner wall of the vessel 22 using its circular sidewall, and the cleaning groove 3101 scrapes and cleans the slurry adhering to the outer wall of the stirring rod 21 using its cleaning groove. As the circular cleaning plate descends, it applies downward pressure to the slurry inside the vessel 22, causing the slurry to be discharged through the discharge pipe 2201, thus eliminating the need for the slurry to rely on its own gravity for discharge. This achieves stable discharge and automatically cleans the slurry adhering to the inner wall of the vessel 22 and the outer wall of the stirring rod 21 during the discharge process. This solves the problem of conventional discharge methods that rely on the gravity of the fluid slurry for discharge, which are prone to incomplete discharge due to the high viscosity of the slurry and the large amount of residue adhering to the wall, ultimately requiring cleaning equipment and resulting in a large amount of slurry waste.

[0023] In an embodiment of the present invention, the slurry cleaning assembly 3 further includes a drive mechanism 32 arranged in the inner cavity of the equipment platform 1. The drive mechanism 32 is a bidirectional lead screw linear movement mechanism driven by a motor. One moving end of the drive mechanism 32 is connected to a moving frame 33, and the other moving end is connected to another moving frame 33. The two moving frames 33 are arranged symmetrically. A drive plate 34 is connected to one side wall of the moving frame 33, and a structure symmetrical to the drive plate 34 is connected to the other side wall. A plurality of guide plates 35 are also arranged on the top of the equipment platform 1, wherein two guide plates 35 are arranged in a staggered state, and the drive plate 34 is slidably arranged on the side wall of the guide plate 35. The side wall of the drive plate 34 is provided with a plurality of inclined grooves 3401, and the side wall of the guide plate 35 is provided with a horizontal groove 3501 and a plurality of vertical grooves 3502. The plurality of vertical grooves 3502 are in communication with the horizontal grooves 3501. A plurality of U-shaped frames 3102 are connected to the top of the semi-circular cleaning plate 31. The other end is connected to multiple drive columns 3103. The outer circumferential wall of the drive column 3103 is connected to a limiting block 3104. The drive column 3103 is movably arranged in the horizontal groove 3501 and extends into the inclined groove 3401. The limiting block 3104 is arranged on the side wall of the guide plate 35. The limiting block 3104 always fits against the side of the guide plate 35 to prevent the drive column 3103 from leaving the groove trajectory. When the drive plate 34 slides on the side wall of the guide plate 35, it can drive its drive column 3103 to slide in the horizontal groove 3501 through the inclined groove 3401 and enter the vertical groove 3502 for vertical sliding.

[0024] In the initial stage of equipment operation, the dual planetary mixer 2 starts, and its U-shaped stirring rod 21 simultaneously revolves and rotates within the vessel 22. Simultaneously, the cleaning blades 23, tilted horizontally at the bottom of the vessel 22, rotate synchronously. This combination forms a three-dimensional mixing range, thoroughly mixing the positive and negative electrode slurries within the vessel 22. After mixing is complete, the dual planetary mixer 2 stops, and the two stirring rods 21 are adjusted to a linearly aligned, stationary state. Then, the cleaning assembly 3 begins operation. The bidirectional lead screw linear movement mechanism driven by the motor of the drive mechanism 32 within the equipment platform 1 starts, driving two symmetrical moving frames 33 to move towards each other. The drive plate 34 on the side wall of the moving frame 33 slides along the side wall of the guide plate 35 at the top of the equipment platform 1. The inclined groove 3401 on the side wall of the drive plate 34 pushes the drive column 3103 connected to the U-shaped frame 3102 to slide within the horizontal groove 3501 of the guide plate 35, causing the two semi-circular cleaning plates 31 to move horizontally towards each other until they merge. In this state, the cleaning groove 3101 of the semi-circular cleaning plate 31 forms a close fit around the outer circumference of the stirring rod 21; then the drive column 3103 enters the vertical groove 3502 of the guide plate 35 and slides vertically, causing the combined semi-circular cleaning plate 31 to descend vertically in the inner cavity of the vessel body 22. Its circumferential sidewall scrapes off the slurry hanging on the inner sidewall of the vessel body 22, and the cleaning groove 3101 scrapes off the slurry hanging on the outer wall of the stirring rod 21. At the same time, pressure is applied to the slurry in the vessel body 22, causing the slurry to flow and be discharged to the bottom discharge pipe 2201. This invention utilizes a plurality of inclined grooves 3401 formed on the side wall of the drive plate 34, and a horizontal groove 3501 and a plurality of vertical grooves 3502 formed on the side wall of the guide plate 35, with the vertical grooves 3502 maintaining communication with the horizontal grooves 3501. When the drive mechanism 32 drives the moving frame 33 and the drive plate 34 to slide along the guide plate 35, the inclined structure of the inclined grooves 3401 generates a combined horizontal and vertical driving force on the drive column 3103: firstly, it pushes the drive column 3103 to slide smoothly within the horizontal groove 3501, ensuring that the two semi-circular cleaning plates 31 are precisely horizontally joined to fit and surround the stirring rod 21; when the drive column 3103 slides to the point where the horizontal groove 3501 and the vertical groove 3502 connect, the inclined groove 3401... The driving force direction of 401 is switched to be mainly vertical, guiding the drive column 3103 into the vertical groove 3502 for stable vertical sliding. This, in turn, drives the merged semi-circular cleaning plate 31 to descend vertically along the inner cavity of the vessel body 22. This achieves the conversion between the horizontal and vertical movement states of the semi-circular cleaning plate 31. Without the need for complex mechanical equipment and power sources, the linear movement of the moving frame 33 is driven by a single power source, the drive mechanism 32. With the structural cooperation of the inclined groove 3401 with the horizontal groove 3501 and the vertical groove 3502, the horizontal power of the moving frame 33 is converted into the continuous horizontal and vertical sliding action of the drive column 3103, thereby driving the semi-circular cleaning plate 31 to complete the automated operation of merging and descending.

[0025] In an embodiment of the present invention, the stirring blade 23 has a horizontally inclined state and a vertically inclined state; in the horizontally inclined state, the stirring blade 23 is in clearance fit with the bottom of the inner cavity of the vessel body 22 for stirring the lithium battery slurry; in the vertically inclined state, one side of the stirring blade 23 can contact the bottom of the vertically descending semicircular cleaning plate 31, and the other side can contact the bottom of the inner cavity of the vessel body 22 for cleaning the slurry adhering to the bottom of the semicircular cleaning plate 31.

[0026] This invention achieves integrated mixing and cleaning functions by designing the mixing blade 23 to be switchable between two tilt states: slightly horizontal and slightly vertical. Combined with its adaptable structure to the vessel body 22 and the semi-circular cleaning plate 31, this allows for the seamless integration of mixing and cleaning functions. During the homogenization stage, the mixing blade 23 maintains a slightly horizontal tilt, forming a gap fit with the bottom of the vessel body 22's inner cavity. As the rotating cylinder 37 rotates, it thoroughly mixes the slurry at the bottom of the vessel body 22, forming a three-dimensional mixing range with the mixing rod 21, preventing slurry sedimentation at the bottom and ensuring uniform mixing. When the semi-circular cleaning plate 31 descends vertically to its lower limit position and completes the connection between the vessel wall and the mixing rod 21... After the wall is cleaned, the cleaning blade 23 switches to a slightly vertical tilt, with one side closely attached to the bottom of the semi-circular cleaning plate 31 and the other side attached to the bottom of the inner cavity of the vessel body 22. When it rotates under the drive of the rotating cylinder 37, it can efficiently scrape off the residual wall slurry at the bottom of the semi-circular cleaning plate 31, preventing the slurry from being reset with the cleaning plate and causing secondary pollution or waste. At the same time, the large amount of slurry cleaned off is pushed to the discharge pipe 2201 by the centrifugal force generated by its rotation, further improving the slurry collection rate. This solves the problem that the semi-circular cleaning plate 31 cannot handle the slurry accumulated at its bottom after cleaning the vessel wall and the stirring rod 21.

[0027] In an embodiment of the present invention, a rotating cylinder 37 is rotatably arranged at the bottom of the inner cavity of the vessel body 22, and a driven gear 38 is connected to the bottom of the rotating cylinder 37. The driven gear 38 is arranged below the vessel body 22. A rotary motor 39 is installed on the inner side wall of the equipment platform 1. A drive gear 310 is connected to the output end of the rotary motor 39. A transmission gear 311 is rotatably arranged at the bottom of the equipment platform 1. The drive gear 310 is meshed with the transmission gear 311, and the transmission gear 311 is meshed with the driven gear 38. The mixing blade 23 is rotatably arranged on the side wall of the rotating cylinder 37 through the bearing 312. The rotary motor 39 on the inner wall of the equipment platform 1 starts, and its output drives the drive gear 310 to rotate. The power is transmitted to the driven gear 38 through the transmission gear 311, and finally drives the rotating cylinder 37 to rotate stably at the bottom of the inner cavity of the vessel body 22. At the same time, the cleaning blade 23 is rotatably mounted on the side wall of the rotating cylinder 37 through the bearing 312. It can rotate around the axis of the rotating cylinder 37 synchronously with the rotation of the rotating cylinder 37 to realize the stirring or cleaning of the slurry at the bottom of the vessel body 22. On the other hand, the setting of the bearing 312 allows the cleaning blade 23 to rotate around its own mounting axis when needed, providing a structural basis for subsequent switching to a horizontal or vertical tilt state. This ensures the stable transmission of power for the circular motion of the cleaning blade 23 and meets the flexibility requirements for its functional state switching.

[0028] In an embodiment of the present invention, a rotating rod 2301 is connected to the side wall of one mixing blade 23, and a rotating sleeve 2302 is connected to the side wall of the other mixing blade 23. The rotating rod 2301 is rotatably arranged in the inner cavity of the rotating sleeve 2302. A half gear 1 2303 is connected to the outer circumference of the rotating rod 2301, and a half gear 2304 is connected to the outer circumference of the rotating sleeve 2302. The tooth positions of the half gear 1 2303 and the half gear 2304 are arranged symmetrically. A plurality of adjusting cylinders 313 are movably arranged in the inner cavity of the rotating cylinder 37. Two adjusting cylinders 313 are arranged symmetrically. A toothed plate 314 is arranged on the outer wall of the adjusting cylinder 313. The toothed plate 314 of one adjusting cylinder 313 is meshed with the half gear 1 2303, and the toothed plate 314 of the other adjusting cylinder 313 is meshed with the half gear 2304. When the two adjusting cylinders 313 move down at the same time, they can drive the two mixing blades 23 to rotate in opposite directions on the same axis. This invention features a design in which two mixing blades 23 are coaxially rotatably connected to a rotating sleeve 2302 via a rotating rod 2301. The tooth positions of the first half-gear 2303 on the outer wall of the rotating rod 2301 and the second half-gear 2304 on the outer wall of the rotating sleeve 2302 are symmetrical. When the two adjusting cylinders 313 are simultaneously moved downwards along the inner cavity of the rotating cylinder 37 under external force, the two adjusting cylinders 313 transmit power synchronously to the first half-gear 2303 and the second half-gear 2304 via toothed plates 314. Because the tooth positions of the first half-gear 2303 and the second half-gear 2304 are symmetrical, when they are subjected to force, they will cause the rotating rod 2301 and the rotating sleeve 2302 to rotate in opposite directions, thereby causing the two mixing blades... The blade 23 rotates coaxially and in opposite directions around the common axis of the rotating rod 2301 and the rotating sleeve 2302. It should be noted that if the cleaning blade 23 rotates in a complete circular path around this common axis, its trajectory will interfere with the top and bottom of the inner cavity of the cleaning chamber 36. Therefore, the rotation range of the cleaning blade 23 is limited to "slightly horizontal tilt" and "slightly vertical tilt", and it only rotates along the switching path between the two states to avoid interference. The synchronous and opposite rotation of the two cleaning blades 23 can ensure that they move independently within their own state switching paths without interfering with each other, which satisfies the state switching requirements and avoids the problem of motion interference.

[0029] In an embodiment of the present invention, a sliding groove 3701 is arranged in the inner cavity of the rotating cylinder 37, and a plurality of insertion holes 3702 are opened on the inner side wall of the sliding groove 3701. An inclined baffle 3703 is arranged on the side of the upper end of the sliding groove 3701. The adjusting cylinder 313 is slidably arranged in the sliding groove 3701. The bottom of the adjusting cylinder 313 is connected to the bottom of the sliding groove 3701 by a spring 315. A plurality of insertion rods 316 are movably arranged on the side wall of the adjusting cylinder 313. The insertion rods 316 can form an insertion engagement with the insertion holes 3702. The top of the toothed edge of the toothed plate 314 can form a limiting contact state with the inclined baffle 3703 to prevent the adjusting cylinder 313 from moving upward excessively. A lifting column 317 is slidably arranged inside the regulating cylinder 313. A drive head 318 is connected to the top of the lifting column 317. The top of the drive head 318 has a conical structure and extends above the regulating cylinder 313. A control plate 319 is connected to the bottom of the lifting column 317. A guide column 320 is connected to the bottom of the control plate 319. A second spring 321 is sleeved on the outer circumference of the guide column 320. The bottom of the control plate 319 is connected to the bottom of the spring chamber inside the regulating cylinder 313 through the second spring 321. An regulating chamber 322 is arranged on the side wall of the regulating cylinder 313. A rod 3... 16 is movably arranged in the adjustment chamber 322. One end of the insertion rod 316 extends to the outside of the adjustment cylinder 313 and the other end extends to the inner cavity of the control plate 319. A stop block 323 is connected to the outer circumference of the insertion rod 316. A spring 324 is arranged between the side wall of the stop block 323 and the inner side wall of the adjustment chamber 322 and sleeved on the outer circumference of the insertion rod 316. A moving column 325 is connected to the end of the insertion rod 316. Multiple drive slots 326 are opened on the side wall of the control plate 319. Two drive slots 326 are arranged in a figure-eight structure. The moving column 325 is movably arranged in the drive slot 326.

[0030] When the semi-circular cleaning plate 31 descends, its bottom contacts and presses against the drive head 318, pushing the drive head 318 to move the lifting column 317 and the control plate 319 at the bottom along the inner cavity of the adjusting cylinder 313, compressing the second spring 321 at the bottom. Because the control plate 319 has a figure-eight drive groove 326 on its side wall, and the moving column 325 at the end of the insertion rod 316 is movably disposed in the drive groove 326, when the control plate 319 moves down, the drive groove 326 will generate a lateral thrust on the moving column 325, causing the insertion rod 316 to overcome the elastic force of the third spring 324 and retract into the adjusting chamber 322, disengaging from the insertion fit with the insertion hole 3702, thus unlocking the adjusting cylinder 313; after unlocking, the adjusting cylinder 31 3. Move down along the sliding groove 3701 and compress the first spring 315. Drive the cleaning blade 23 to switch to a vertical tilt state through the toothed plate 314. When the semi-circular cleaning plate 31 rises and the pressure of the drive head 318 disappears, the first spring 315 releases its elastic force first, pushing the adjusting cylinder 313 to move up until the top of the tooth of the toothed plate 314 forms a limiting contact state with the bottom of the inclined baffle 3703. The cleaning blade 23 returns to a horizontal tilt state. Then the second spring 321 pushes the control plate 319 to reset. The thrust of the drive groove 326 on the moving column 325 is released. The insertion rod 316 is reset under the action of the third spring 324 and re-inserted into the insertion hole 3702, locking the adjusting cylinder 313.

[0031] This invention, through the design of a locking structure for the adjusting cylinder 313, ensures that during the homogenization stage, the insertion and locking of the insertion rod 316 and the insertion hole 3702 stably fixes the adjusting cylinder 313 at a specific height within the sliding groove 3701. This ensures precise meshing between the toothed plate 314 and the half-gear of the mixing blade 23, allowing the mixing blade 23 to maintain a stable, slightly horizontal tilt. This prevents the mixing blade 23 from experiencing excessive lateral thrust due to the viscosity of the slurry during mixing, which could lead to angular displacement and affect the mixing effect. During the clearing stage... When the semi-circular cleaning plate 31 presses down on the driving head 318, it triggers the adjusting cylinder 313 to unlock and move downward. The toothed plate 314 drives the cleaning blade 23 to switch to a slightly vertical tilted state to clean the slurry adhering to the wall. After cleaning, the springs 1 315 and 2 321 can automatically push the adjusting cylinder 313 and the control plate 319 to reset, and the insertion rod 316 relocks the adjusting cylinder 313. This structure effectively solves the problems of the cleaning blade 23 state switching relying on complex external power and manual intervention, low switching accuracy and poor stability.

[0032] The present invention also designs the top of the drive head 318 as a conical structure so that the slurry pressure it receives can be evenly distributed along the conical surface, avoiding the pressure generated by the slurry causing the drive head 318 to move downward, ensuring that the drive head 318 always maintains a stable position during the homogenization stage and does not trigger the unlocking action of the regulating cylinder 313, thereby ensuring that the cleaning blade 23 continuously maintains a slightly horizontal tilt state to efficiently stir the slurry.

[0033] In an embodiment of the present invention, a pressure block 3105 is also installed in the inner cavity of the semi-circular cleaning plate 31. The bottom of the pressure block 3105 is flush with the bottom of the semi-circular cleaning plate 31. A circular groove is provided at the bottom of the pressure block 3105. A pressure head 3106 is rotatably arranged in the circular groove. The bottom of the pressure head 3106 has a concave conical structure. The pressure head 3106 can form an insertion fit with the drive head 318 through the concave conical structure at the bottom. Multiple discharge grooves 3107 are provided on the concave conical structure at the bottom of the pressure head 3106. When the semi-circular cleaning plate 31 moves downward, the pressure block 3105 installed in its inner cavity descends synchronously with the cleaning plate. As the semi-circular cleaning plate 31 continues to move downward to near the position of the adjusting cylinder 313, the pressure head 3106, which is rotatably arranged in the bottom circular groove of the pressure block 3105, will have its bottom concave conical structure contacting the outer convex conical structure of the drive head 318, ultimately forming a plug-in fit. At this time, the downward pressure of the semi-circular cleaning plate 31 is stably transmitted to the drive head 318 through the pressure head 3106, pushing the lifting column 317 and the control plate 319 downward, thereby triggering the unlocking of the adjusting cylinder 313 and the state switching of the cleaning blade 23. During this process, the pressure head 3105... The discharge groove 3107 on the concave conical structure 06 can promptly guide and discharge the slurry squeezed during the insertion and mating process, avoiding the accumulation of slurry between the conical mating surfaces and causing jamming. Since the drive head 318 rotates synchronously with the rotating drum 37, the rotation design of the pressure head 3106 can form a dynamic fit between it and the drive head 318, reducing the frictional resistance between the drive head 318 and the pressure head 3106 during the rotation process. This avoids excessive friction causing wear and jamming of the conical mating surfaces, or affecting the normal rotation of the cleaning blades 23 driven by the rotating drum 37. This ensures the service life of the components and ensures that the cleaning action of the cleaning blades 23 is stable and efficient.

[0034] Example 2: This example provides a method for using a homogenizing device for positive and negative electrode slurries of lithium batteries, including the following steps: S1. Homogenization Operation: First, the positive or negative electrode slurry of the lithium battery is put into the reactor body 22, and then the equipment is started to begin the homogenization operation. The double planetary mixer 2 is used to drive the two U-shaped stirring rods 21 to revolve and rotate simultaneously in the inner cavity of the reactor body 22, so as to mix the slurry in the reactor body in all directions. At the same time, the rotary motor 39 on the inner side wall of the equipment platform 1 is started. Through the meshing transmission of the drive gear 310, transmission gear 311 and driven gear 38, the rotating cylinder 37 at the bottom of the inner cavity of the reactor body 22 is rotated. At this time, the cleaning blades 23 are in a slightly horizontal inclined state, maintaining a gap fit with the bottom of the inner cavity of the reactor body 22, and rotating synchronously with the rotating cylinder 37 to stir the slurry at the bottom of the reactor body 22. Together with the stirring rods 21, a three-dimensional stirring range is formed to avoid slurry sedimentation and ensure that the materials are fully mixed to form a homogeneous slurry. S2. Slurry cleaning and discharge operation: After the homogenization operation is completed, the double planetary mixer 2 stops running, and the two mixing rods 21 are adjusted to a linearly aligned stationary state, and the preset position of the cleaning blades 23 is adjusted. Then, the slurry cleaning assembly 3 is started to discharge and clean the wall. The bidirectional screw linear movement mechanism of the drive mechanism 32 is started, driving the two symmetrical moving frames 33 to move towards each other. The moving frames 33 drive the drive plate 34 to slide along the guide plate 35. The inclined groove 3401 on the side wall of the drive plate 34 pushes the drive column 3103 to slide in the horizontal groove 3501 of the guide plate 35, causing the two semi-circular cleaning plates 31 to move horizontally towards each other to a merged state. At this time, the cleaning grooves 3101 of the semicircular cleaning plate 31 merge to form a circular groove that fits the stirring rod 21, forming a close fit around the outer circumference of the stirring rod 21; as the drive plate 34 continues to slide, the drive column 3103 slides vertically from the horizontal groove 3501 into the vertical groove 3502, driving the merged semicircular cleaning plate 31 to descend vertically in the inner cavity of the vessel body 22; during the descent, the circumferential sidewall of the semicircular cleaning plate 31 scrapes off the slurry adhering to the inner sidewall of the vessel body 22, and the cleaning groove 3101 scrapes off the slurry adhering to the outer circumferential sidewall of the stirring rod 21, while applying downward pressure to the slurry in the vessel body, pushing the slurry to flow and be discharged through the bottom discharge pipe 2201; S3. Slurry cleaning operation at the bottom of the semi-circular cleaning plate: When the semi-circular cleaning plate 31 descends to the lower limit position, its bottom forms a closed cleaning chamber 36 with the bottom of the inner cavity of the vessel body 22. During this process, the pressure block 3105 in the inner cavity of the semi-circular cleaning plate 31 descends synchronously with the cleaning plate. The pressure head 3106 at the bottom of the pressure block 3105 forms an insertion fit with the conical drive head 318 at the top of the regulating cylinder 313 through the concave conical structure. The discharge groove 3107 on the pressure head 3106 promptly discharges the slurry squeezed during the insertion to avoid jamming. The downward pressure of the semi-circular cleaning plate 31 is transmitted to the drive head 318 through the pressure head 3106, pushing the lifting column 317 and the control plate 319 to move down and compress the second spring 321. The figure-eight drive groove 326 on the side wall of the control plate 319 drives the moving column 325 to move, so that the insertion rod 316 overcomes the elastic force of the third spring 324 and contracts. The cylinder 313 is unlocked by disengaging from the insertion hole 3702 on the sliding groove 3701 of the rotating cylinder 37. After unlocking, the adjusting cylinder 313 continues to move down along the sliding groove 3701 and compresses the first spring 315. The toothed plates 314 on the outer walls of the two adjusting cylinders 313 mesh with the first half gear 2303 and the second half gear 2304 respectively. Since the teeth of the first half gear 2303 and the second half gear 2304 are symmetrical, the rotating rod 2301 and the rotating sleeve 2302 are driven to rotate in opposite directions on the same axis, thereby causing the two cleaning blades 23 to switch to a slightly vertical tilted state. At this time, one side of the cleaning blade 23 is attached to the bottom of the semi-circular cleaning plate 31, and the other side is attached to the bottom of the inner cavity of the vessel body 22. As the rotating cylinder 37 rotates, it scrapes off the slurry hanging on the bottom of the semi-circular cleaning plate 31, and pushes the cleaned slurry to the discharge pipe 2201 for discharge by the centrifugal force generated by the rotation. S4. Reset Operation: After the slurry is completely discharged, the slurry cleaning component 3 begins to reset. The drive mechanism 32 runs in reverse, causing the moving frame 33 and drive plate 34 to slide in the opposite direction. The drive column 3103 resets along the vertical groove 3502 and horizontal groove 3501. The semi-circular cleaning plate 31 rises synchronously and separates to its initial position. After the semi-circular cleaning plate 31 rises, the pressure on the drive head 318 disappears. Spring 1 315 releases its elastic force first, pushing the adjusting cylinder 313 upward until the top of the toothed edge of the toothed plate 314 forms a limited contact state with the bottom of the inclined baffle 3703. The cleaning blade 23 returns to its inclined state in the horizontal direction. Then, spring 2 321 pushes the control plate 319 to reset. The thrust of the drive groove 326 on the moving column 325 is released. The insertion rod 316 resets under the action of spring 3 324 and re-inserts into the insertion hole 3702, locking the adjusting cylinder 313. Then, the inner cavity of the vessel body 22 is cleaned by external cleaning equipment. The equipment completes a complete slurry mixing, discharge and cleaning operation.
