Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery processing, and particularly to a high-efficiency mixing processing device for lithium battery slurry based on slurry flow control. Background Art

[0002] In the production process of lithium batteries, the mixing quality of lithium battery slurry plays a crucial role in the performance and stability of the batteries. High-quality slurry mixing can ensure the uniform dispersion of components such as active materials, conductive agents, and binders, thereby improving the charge and discharge performance, cycle life, and safety of lithium batteries. Currently, most of the common lithium battery slurry mixing processing devices on the market adopt traditional stirring methods. Among them, the planetary mixer rotates around its axis while revolving, simulating the manual stirring action to try to enhance the mixing effect. However, when dealing with high-viscosity lithium battery slurry, the shear force between the stirring paddle and the slurry is insufficient, resulting in a large number of undispersed aggregates inside the slurry, and the mixing uniformity is difficult to meet the standard. The double-shaft paddle mixer relies on the paddles arranged alternately on two stirring shafts to stir the slurry in opposite directions. Although it has a certain mixing ability, its paddle structure makes the flow of the slurry in the axial and radial directions relatively single, unable to form complex turbulence, and difficult to break the bubbles and density stratification in the slurry, affecting the quality of the final product. The high-speed disperser uses a high-speed rotating dispersing disk to disperse and mix the slurry by using centrifugal force and shear force. However, this method will generate a large local shear force during the mixing process, resulting in over-dispersion of some raw materials while insufficient mixing in other areas. At the same time, the high energy consumption problem brought by high-speed rotation also increases the production cost. These traditional devices generally have problems such as insufficient mixing, low efficiency, difficulty in achieving fine processing of the slurry, inability to effectively control the flow path of the slurry, resulting in local uneven mixing of raw materials during the mixing process, and some devices having insufficient disturbance to the slurry during the mixing process, resulting in a long mixing time and large energy consumption, unable to meet the increasing high-efficiency and high-quality requirements of lithium battery production. Therefore, it is of great practical significance to develop a lithium battery slurry processing device that can achieve efficient mixing and precise flow control. Summary of the Invention

[0006] The mixing barrel and the upper cover are provided with a flow disturbance mechanism, which further enhances the mixing effect of the slurry by disturbing the slurry during the directional transportation of the slurry;

[0007] The spoiler mechanism includes: an electric push rod, which is fixedly mounted on the upper surface of the upper cover, and the lower end of the electric push rod passes through the inner top surface of the upper cover, and the lower end of the electric push rod is rotatably connected to the displacement gear, the upper end of the rotating shaft of the linkage gear on one side is fixedly connected to the lower functional gear, the outer surface of the partition plate is fixedly provided with a sliding cylinder, and the upper end of the sliding cylinder is fixedly connected to the inner top surface of the mixing barrel, the upper end of the sliding cylinder on one side is provided with a rotating displacement rod, the lower end of the mixing barrel is provided with a sliding displacement disk, and the upper surface of the displacement disk is fixedly provided with a displacement cylinder, the inner surfaces of the mixing barrel on the upper and lower sides of the displacement disk are fixedly provided with blocks, the outer surface of the displacement disk is provided with a rotating rotating cylinder, and the inner surface of the rotating cylinder is fixedly provided with a paddle.

[0008] Preferably, the lower surface of the central disk is in contact with the upper ends of the feed pipe and the discharge pipe, the outer surface of the central disk is in contact with the inner surface of the mixing barrel, and the upper surface of the central disk is in contact with the lower surface of the bottom plate. There are 2 relief holes, and the 2 relief holes are respectively aligned with the feed pipe and the discharge pipe.

[0009] By adopting the above technical solution, accurate communication control between the feed pipe and the discharge pipe and the inside of the mixing barrel is achieved. By rotating the central disk, the relief opening and the relief hole are aligned or misaligned, so that the feeding, mixing, and discharging states can be accurately switched, avoiding interference and leakage of raw materials between different processes, and ensuring the sealing performance and process controllability of the mixing process.

[0010] Preferably, there is a gap between the upper end of the central cylinder and the lower surface of the partition plate, and the central cylinder and the central column are concentrically arranged. The outer surface of the discharge rod is provided with spiral blades, and the outer surface of the spiral blades of the discharge rod is in contact with the inner surface of the central column, and there is a gap between the outer surface of the central column and the inner surface of the central cylinder.

[0011] By adopting the above technical solution, with the fitting design of the spiral blades of the discharge rod and the inner side of the central column, a spiral conveying channel is formed when the discharge rod rotates, and the slurry above the partition plate can be conveyed downward along the inner side of the central column and discharged into the gap area between the central cylinder and the central column through the discharge groove. Cooperating with the gap between the upper end of the central cylinder and the partition plate, the directional diversion of the slurry from the top to the middle is realized, providing power for the convective mixing of the slurry in the upper and lower regions.

[0012] Preferably, the upper end of the guide column penetrates through the upper surface of the partition plate. The outer surface of the guide rod is provided with spiral blades, and the outer surface of the spiral blades of the guide rod is in contact with the inner surface of the guide column.

[0013] By adopting the above technical solution, the spiral blades on the outer side of the guide rod are closely attached to the inner side of the guide column. When the guide rod rotates, the slurry at the bottom of the mixing barrel can be sucked into the guide column from the feed groove and conveyed upward along the spiral path to the upper part of the partition plate, forming a material lifting channel from the bottom to the top, which forms a circulating convection with the downward conveying path of the discharge rod, enhancing the mixing flow of the slurry in the vertical direction.

[0014] Preferably, the central gear is meshed with the linkage gear, the linkage gear and the upper functional gear are concentrically arranged, and the rotating shaft of the upper functional gear is fixedly connected with the output shaft of the guide motor.

[0015] By adopting the above technical solution, the power of the guide motor is synchronously transmitted to the discharge rod and the guide rod through the meshing transmission of the center gear and the linkage gear, so that the two rotate in opposite directions under the drive of the guide motor, respectively realizing the upward and downward conveying of the slurry, ensuring the coordinated dual-path circulation mixing action of the slurry guide mechanism, and improving the guide efficiency and mixing uniformity.

[0016] Preferably, the lower end of the displacement gear is slidably connected to the upper end of the displacement rod, and the displacement rod is threadedly connected to the displacement cylinder directly below.

[0017] By adopting the above technical solution, the sliding connection between the displacement gear and the displacement rod is combined with the threaded transmission structure, so that when the displacement gear rotates, it can drive the displacement disk through the displacement rod to perform reciprocating linear motion in the mixing barrel, providing vertical displacement power for the spoiler mechanism, so that the paddle blades generate dynamic disturbances on the slurry during the up and down movement.

[0018] Preferably, the lower functional gear is meshed with the displacement gear, and the lower functional gear and the upper functional gear are staggered in the vertical direction, and the vertical projection of the lower functional gear is meshed with the vertical projection of the upper functional gear.

[0019] By adopting the above technical solution, the meshing relationship between the lower functional gear and the displacement gear and the staggered setting with the upper functional gear enable the displacement gear to alternately mesh with the upper functional gear and the lower functional gear when it moves up and down driven by the electric push rod, thereby realizing the forward and reverse rotation switching of the displacement gear, driving the displacement rod to periodically change the rotation direction, so that the up and down movement of the displacement disk and the rotation of the blade form a composite disturbance, thereby enhancing the shearing and mixing effect on the slurry.

[0020] Preferably, the outer surface of the displacement disk is in contact with the inner surface of the mixing barrel, and the displacement disk is in sliding friction connection with the central tube and the guide column, and the two blades are arranged facing each other.

[0021] By adopting the above technical solution, the fit between the displacement disk and the inner surface of the mixing barrel, as well as the sliding friction connection with the central barrel and the guide column, ensures the sealing and stability of the displacement disk when it moves up and down, and avoids the slurry from flowing in the upper and lower areas of the displacement disk. The blades arranged in opposite directions can generate bidirectional shear force on the slurry when rotating with the rotating barrel, and cooperate with the vertical movement of the displacement disk to form a complex turbulent flow field in the mixing barrel, effectively breaking the bubbles and density stratification in the slurry, and significantly improving the mixing uniformity and efficiency.

[0022] Compared with the prior art, the present invention has the following beneficial effects: the lithium battery slurry efficient mixing and processing device based on slurry flow control:

[0023] 1. By setting up a slurry diversion mechanism and the cooperation of components such as the central cylinder, central column, discharge chute, and discharge rod, the slurry can be directionally diverted, enabling the raw materials to flow along a preset path. This effectively solves the problem that traditional devices cannot control the slurry flow path, resulting in uneven local mixing, ensures the uniformity of slurry mixing, and the structures such as the diversion column, feed chute, and diversion rod work together to achieve the orderly transportation of the slurry, further enhancing the mixing effect;

[0024] 2. Components such as the electric push rod, displacement gear, and displacement rod of the turbulence mechanism can dynamically disturb the slurry during the slurry transportation process. Compared with the defect of insufficient disturbance in traditional devices, the present invention can form complex turbulence, break the bubbles and density stratification in the slurry, enhance the thoroughness of mixing, improve the mixing efficiency, and reduce the mixing time;

[0025] 3. The fitting design of the central disk with the feed pipe, discharge pipe, and mixing barrel, combined with the control of the solenoid valve, realizes precise control of feeding and discharging, avoids waste of raw materials and mixing residues, and at the same time helps to improve the automation level of the mixing process.
