Description

Technical Field

[0001] This utility model relates to the field of battery slurry storage technology, and in particular to a storage tank for preparing lithium battery slurry. Background Technology

[0002] In the production and preparation of lithium batteries, the storage of slurry is a critical step. Lithium battery slurry is mainly composed of active materials, conductive agents, binders, and solvents, and is a solid-liquid two-phase mixture. When stored statically, it is prone to sedimentation and stratification of solid particles, which leads to a decrease in the uniformity of the slurry and directly affects the quality of subsequent coating processes and the performance of the final battery product.

[0003] To prevent slurry sedimentation, existing storage tanks typically have a fixed agitator inside. This agitator, driven by a motor, slowly and intermittently stirs the slurry to maintain its suspension. However, this type of fixed agitator has significant drawbacks: firstly, the complex structure of the agitator blades and supporting rods creates numerous cleaning dead zones within the tank; secondly, after storing one batch of slurry, the tank and its internal components require thorough cleaning to prevent cross-contamination between different batches. However, because the agitator is fixed, cleaning is extremely inconvenient, time-consuming, labor-intensive, and difficult to ensure complete cleaning. Residual slurry may dry and detach, becoming impurities in the next batch. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a storage tank for preparing lithium battery slurry, so as to solve the technical problems in the prior art.

[0005] To achieve the above objectives, this utility model provides a storage tank for preparing lithium battery slurry, comprising a tank body and a T-shaped mounting hole opened on the top of the tank body, and further comprising: A detachable positioning ring is installed in the T-shaped assembly hole. A counterweight plate is rotatably installed in the positioning ring, and the counterweight plate has a through hole in the middle, through which a rotating shaft moves. At least one first hinge plate is hinged to the side wall of the rotating shaft, and a stirring component for stirring the lithium battery slurry inside the tank is hinged to one end of the first hinge plate. A second hinge plate is hinged to the upper end of the stirring component. A movable sleeve is hinged to one end of the second hinge plate and is fitted onto the upper end of the rotating shaft. The top of the movable sleeve is fixedly connected to the bottom of the counterweight plate. Drive components for driving the rotation of the shaft; Limiting components used to restrict the rotation of the positioning ring.

[0006] Preferably, the T-shaped assembly hole includes an upper large-diameter hole section and a lower small-diameter hole section arranged coaxially, and an annular stepped plane is formed between the upper large-diameter hole section and the lower small-diameter hole section, and the bottom end face of the counterweight plate abuts against the stepped plane.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0019] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] The first aspect of this utility model provides a storage tank for preparing lithium battery slurry, such as... Figure 1-5 As shown, the device includes a tank body 1 and a T-shaped assembly hole 101 opened on the top of the tank body 1, and also includes: A positioning ring 2 is detachably installed in the T-shaped assembly hole 101. A counterweight plate 3 is rotatably installed inside the positioning ring 2, and the center of the counterweight plate 3 has a through hole, through which a rotating shaft 4 is movably inserted. At least one first hinge plate 5 is hinged to the side wall of the rotating shaft 4. One end of the first hinge plate 5 is hinged to a stirring element 6 for stirring the lithium battery slurry inside the tank 1. It should be added that the stirring element 6 has a U-shaped structure. When the stirring element 6 rotates, it can further increase the contact area with the lithium battery slurry to improve the stirring effect. A second hinge plate 7 is hinged to the upper end of the stirring component 6. A movable sleeve 8 is hinged to one end of the second hinge plate 7, and the movable sleeve 8 is fitted onto the upper end of the rotating shaft 4. The top of the movable sleeve 8 is fixedly connected to the bottom of the counterweight plate 3. Drive assembly for driving the rotation of shaft 4; Limiting assembly used to restrict the rotation of positioning ring 2.

[0021] When cleaning the agitator 6 is required after use, the positioning ring 2 is pulled upwards. During this upward movement, the positioning ring 2 drives the rotating counterweight plate 3 to rise, causing the counterweight plate 3 to slide the bottom-fixed movable sleeve 8 upwards towards the rotating shaft 4. At this time, the movable sleeve 8 moves upwards, causing the hinged second hinge plate 7 to deflect, which in turn causes the agitator 6 to move closer to the rotating shaft 4 and gather together. After the counterweight plate 3 moves into position, multiple agitators 6 gather together due to the deflection of the second hinge plate 7. By continuing to pull the positioning ring 2 upwards, the rotating shaft 4 moves the gathered agitators 6 out of the T-shaped assembly hole 101, making it easy to disassemble and clean the agitator 6 from inside the tank 1. This solves the problem of many dead corners and inconvenient cleaning in traditional fixed agitators, allowing the inside of the tank 1 and the agitator components themselves to be cleaned quickly and thoroughly, effectively avoiding cross-contamination between different batches of slurry and ensuring product quality.

[0022] In this embodiment, the T-shaped assembly hole 101 includes an upper large-diameter hole section and a lower small-diameter hole section arranged coaxially. An annular stepped plane is formed between the upper large-diameter hole section and the lower small-diameter hole section, and the bottom end face of the counterweight plate 3 abuts against the stepped plane. In this way, the axial positioning of the counterweight plate 3 is defined, preventing it from falling downwards.

[0023] In this embodiment, a bearing is provided between the side wall of the counterweight disk 3 and the inner wall of the positioning ring 2, with the inner ring of the bearing fixedly connected to the side wall of the counterweight disk 3 and the outer ring of the bearing fixedly connected to the inner wall of the positioning ring 2. The bearing arrangement further improves the stability of the rotation of the counterweight disk 3.

[0024] In this embodiment, the bottom of the counterweight disk 3 has multiple grooves evenly spaced along the circumferential direction, and each groove is fitted with a rolling ball, the bottom of which abuts against the stepped plane. This reduces the contact area between the bottom of the counterweight disk 3 and the stepped plane, thereby reducing friction and improving the rotational stability of the counterweight disk 3.

[0025] In this embodiment, keyways are provided on both sides of the upper end of the rotating shaft 4, and flat keys that mate with the keyways are symmetrically fixed on the inner wall of the movable sleeve 8. By cooperating with the keyways on the inner wall of the movable sleeve 8, the movable sleeve 8 can be driven to rotate synchronously and stably during the rotation of the rotating shaft 4.

[0026] In this embodiment: the driving component includes: The first gear 9 is fixed to the top of the rotating shaft 4. It should be noted that the diameter of the first gear 9 is greater than or equal to the diameter of the positioning ring 2, so that the positioning ring 2 can be removed without interference.

[0027] A motor 10 is fixed to the top of the tank 1. A second gear 11 is fixedly installed at the output end of the motor 10, and the second gear 11 meshes with the first gear 9. When stirring the lithium battery slurry inside the tank 1 to prevent sedimentation and stratification, the second gear 11 at the output end of the motor 10 meshes with the first gear 9 at the top of the rotating shaft 4, causing the rotating shaft 4 to rotate. At this time, the rotating shaft 4 drives the first hinge plate 5 and the movable sleeve 8 to rotate simultaneously, causing the stirring component 6 driven by the first hinge plate 5 to rotate. At the same time, the movable sleeve 8 drives the counterweight plate 3 to rotate synchronously, so that the stirring component 6 can uniformly stir the lithium battery slurry inside the tank 1 and prevent the lithium battery slurry from sedimenting and stratifying.

[0028] In this embodiment: the limiting component includes: At least one fixing block 12 is fixed to the top of the tank body 1, and a bolt 13 is threaded in the middle of the fixing block 12 in the horizontal direction; The side wall of the positioning ring 2 has at least one threaded groove, and one end of the bolt 13 is threaded into the threaded groove.

[0029] It should be added that bolt 13 can be provided with two ends and positioned opposite each other on the top of tank body 1 to enhance the stability of locking the positioning ring 2; To improve the stability of the counterweight disc 3's rotation, after placing the rotating shaft 4 and the stirring component 6 inside the tank body 1 through the T-shaped assembly hole 101, the rotating bolt 13 is screwed into the threaded groove on the side wall of the corresponding positioning ring 2, locking the positioning ring 2 in place and preventing it from rotating synchronously with the counterweight disc 3. This enhances the stability of the counterweight disc 3's rotation and also restricts the upward movement of the rotating shaft 4, enhancing the stability of the meshing between the second gear 11 and the first gear 9. It also facilitates the disassembly and assembly of the positioning ring 2, and the entire disassembly and cleaning process requires no complex tools. The operation is simple and quick, significantly reducing the labor intensity and time cost for maintenance personnel, and greatly improving the convenience and work efficiency of the storage tank during use and maintenance.

[0030] In this embodiment, two sets of first hinge plates 5 are provided, with three first hinge plates 5 in each set. The three first hinge plates 5 are equidistantly hinged to the side wall of the rotating shaft 4 along the circumference. On the one hand, this improves the stability of the movement of the stirring component 6. On the other hand, as the rotating shaft 4 drives the hinged first hinge plates 5 to rotate, the first hinge plates 5 drive the stirring component 6 to rotate, thereby slowly stirring the lithium battery slurry in the storage tank and preventing the lithium battery slurry from settling and stratifying.

[0031] In this embodiment, handles are symmetrically fixedly installed on the outer side wall of the positioning ring 2. The handles facilitate the vertical upward pulling of the positioning ring 2. As the positioning ring 2 rises, the movable sleeve 8 at the bottom of the counterweight plate 3 rises synchronously, so that the movable sleeve 8 can drive the hinged stirring component 6 to retract closer to the rotating shaft 4.

[0032] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0033] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
