Description

Technical Field

[0001] The utility model belongs to the field of stirring devices, and particularly relates to a slurry stirring device. Background Art

[0002] Batching (also known as slurry mixing, pulp mixing, slurry adjusting, pulp making, stirring) is a key process in the manufacturing of lithium-ion batteries. The uniformity of the slurry has a significant impact on the electrical performance of the battery cells. Generally, a dispersion disc is used to improve the uniformity of the slurry.

[0003] When operating a traditional mixer, it is often necessary to adjust the position of the dispersion disc to adapt to different liquid levels. However, the existing adjustment devices are often inefficient or complex to operate. Moreover, the dispersion disc on the dispersion shaft can only be fixed in one position, resulting in only local dispersion, which reduces the uniformity of the slurry, thereby affecting the performance of the battery cells. Most slurry stirring devices are integrated, making them inconvenient to replace and difficult to clean after damage. Summary of the Utility Model

[0075] Combined with Figures 1 to 4 As shown, a slurry stirring device of the present utility model is used for mixing the slurry for batteries and includes:

[0076] A fixing frame 100, on which an installation member 200 is provided;

[0077] A stirring mechanism 300, which is installed on the installation member 200 and is used for stirring the slurry;

[0078] A lifting and dispersing mechanism 400, which is installed on the fixing frame 100 and is used for adjusting according to the height of the slurry;

[0079] A feeding structure 500, which is installed on the fixing frame 100;

[0080] Among them, the lifting and dispersing mechanism 400 includes a lifting mechanism 410, a servo motor 420, a dispersing column 430 and several dispersing disks 440;

[0081] The lifting mechanism 410 is fixedly arranged inside the installation member 200;

[0082] The servo motor 420 is installed on the output end of the lifting mechanism 410 and is located inside the installation member 200;

[0083] The dispersing column 430 is fixedly arranged on the output shaft of the servo motor 420, and the dispersing column 430 extends from inside the installation member 200 to outside the installation member 200;

[0084] Several of the dispersing disks 440 are all installed on the dispersing column 430.

[0085] A slurry stirring device of the present utility model uses a fixing frame 100 to carry a stirring mechanism 300. The stirring mechanism 300 is used to uniformly stir the slurry. A lifting mechanism 410 is used to drive a servo motor 420, a fixing column, and a dispersion disc 440 to lift. After the dispersion disc 440 can lift, it can stir the component containing slurry on a feeding structure 500 and disperse the slurry, and can lift cyclically to achieve the purpose of uniform dispersion at different liquid levels, improving the dispersion uniformity of the slurry, thereby improving the performance of the battery cell. Since the feeding mechanism and the stirring mechanism 300 are separated, after stirring is completed, clean water can be directly added and preliminarily cleaned through the stirring mechanism 300. By removing the loading component transported by the feeding mechanism, cleaning can be carried out again. The stirring mechanism 300 can replace the stirring part 323, so as to better clean the loading component transported by the feeding mechanism.

[0086] In one embodiment, the feeding structure 500 includes a feeding table 510, a limiting slide rail 520, a sliding member 530, a loading bucket 540, and a pushing and pulling block 550;

[0087] The feeding table 510 is arranged on the fixing frame 100;

[0088] The limiting slide rail 520 is fixedly arranged on the feeding table 510;

[0089] The sliding member 530 is slidably connected to the feeding table 510 through the limiting slide rail 520;

[0090] An installation groove 531 adapted to the size of the loading bucket 540 is arranged on the sliding member 530. The loading bucket 540 is placed in the installation groove 531, and a discharging structure 541 is arranged on the loading bucket 540;

[0091] The pushing and pulling block 550 is installed on the loading bucket 540.

[0092] In this embodiment, the feeding table 510 is used to carry the limiting slide rail 520, the sliding member 530, and the loading bucket 540. A user, an external manipulator, or other components that can push the pushing and pulling block 550 can drive the sliding member 530 and the loading bucket 540 to move, and finally move the loading bucket 540 to the bottom of the installation member 200.

[0093] It should be noted that the opening diameter of the loading bucket 540 is smaller than the diameter of the installation member 200. Therefore, when the loading bucket 540 moves to the bottom of the installation member 200 for stirring, the slurry will not splash out of the loading bucket 540.

[0094] In one embodiment, a hollow part 532 is arranged at the bottom of the sliding member 530, and fixing blocks 533 are symmetrically arranged on the hollow part 532;

[0095] Each of the fixed blocks 533 is provided with a groove 534;

[0096] It further includes a jacking member 600;

[0097] The jacking member 600 includes a cylinder 610 and a top block 620;

[0098] The cylinders 610 are symmetrically and fixedly arranged on the fixed frame 100 and are located below the feeding structure 500;

[0099] The feeding structure 500 is provided with through holes 560 adapted to the number of the cylinders 610.

[0100] In this embodiment, by starting the cylinder 610, the cylinder 610 drives the top block 620 to move into the groove 534. The shape of the top block 620 is the same as that of the groove 534. Therefore, the top block 620 can prevent the sliding member 530 from shifting when rising.

[0101] It should be noted that the width of the through hole 560 is greater than the width of the output end of the cylinder 610, and the length of the through hole 560 is greater than the length of the top block 620, so as not to affect the rising of the top block 620, and the center axis in the top view of the top block 620 coincides with the center axis in the top view of the groove 534.

[0102] In one of the embodiments, it further includes a locking member 700;

[0103] The locking member 700 includes a driving member 710 and a locking column 720;

[0104] The driving member 710 is installed on one side of the fixed frame 100;

[0105] The locking column 720 is installed on the output end of the driving member 710;

[0106] The fixed frame 100 is symmetrically provided with through holes 110 adapted to the size of the locking column 720, and the central axis of the through hole 110 coincides with the central axis of the locking column 720;

[0107] The feeding structure 500 is provided with locking holes 570 adapted to the size of the locking column 720.

[0108] In this embodiment, when the loading bucket 540 is tightly pressed against the bottom of the mounting member 200, the central axis of the locking hole 570 on the sliding member 530 coincides with the central axis of the locking column 720. At this time, the driving member 710 is started to drive the locking column 720 to move. The locking column 720 penetrates through the locking hole 370 and moves into one of the through holes 110 on the fixed frame 100, so as to prevent the sliding member 530 from sliding violently during the slurry stirring, thus affecting the overall stirring.

[0109] In one embodiment, the stirring mechanism 300 includes a driving structure 310 and a stirring structure 320;

[0110] The driving structure 310 is installed on the mounting member 200;

[0111] The stirring structure 320 is symmetrically installed on the mounting member 200;

[0112] Wherein, the driving structure 310 is used to drive the stirring structure 320 to rotate;

[0113] The driving structure 310 includes a driving motor 311 and a transmission gear 312;

[0114] The driving motor 311 is installed inside the mounting member 200;

[0115] The transmission gear 312 is fixedly arranged on the output shaft of the driving motor 311, and the transmission gear 312 is located inside the mounting member 200;

[0116] The stirring structure 320 includes a driven gear 321, a rotating rod 322 and a stirring part 323;

[0117] The driven gear 321 meshes with the transmission gear 312;

[0118] The rotating rod 322 is fixedly arranged at the bottom of the transmission gear 312;

[0119] The stirring part 323 is fixedly arranged at one end of the rotating rod 322 away from the driven gear 321, and the stirring part 323 is located outside the mounting member 200.

[0120] In this embodiment, the driving motor 311 drives the transmission gear 312 to rotate. After the transmission gear 312 rotates, it drives the driven gear 321 to rotate, thereby driving the rotating rod 322 and the stirring part 323 to rotate, so that the stirring part 323 stirs the slurry.

[0121] In one embodiment, a plurality of feed pipes 210 are arranged on the outer wall of the mounting member 200, and each feed pipe 210 is provided with a feed channel 211, and the feed channel 211 extends to the bottom of the mounting member 200.

[0122] In this embodiment, the feed pipe 210 is connected through an external feed pump to introduce external materials. At this time, the loading bucket 540 needs to be pressed tightly against the bottom of the mounting member 200. During the preliminary cleaning, clean water can also be introduced through a water pump, so as to start the stirring member to complete the preliminary cleaning.

[0123] In one embodiment, an annular block 220 is arranged at the bottom edge of the mounting member 200.

[0124] In this embodiment, the annular stopper 220 is used to better prevent the slurry from splashing out of the material loading bucket 540 during stirring.

[0125] Working principle of the present utility model:

[0126] The stirring mechanism 300 is carried by the fixing frame 100. The stirring mechanism 300 is used for uniformly stirring the slurry. The lifting mechanism 410 is used to drive the servo motor 420, the fixing column and the dispersion disc 440 to lift. After the dispersion disc 440 can lift, it can stir the component loaded with the slurry on the feeding structure 500 and disperse the slurry, and can lift cyclically to achieve the purpose of uniform dispersion at different liquid levels, improve the dispersion uniformity of the slurry, thereby improving the performance of the battery cell. Since the feeding mechanism and the stirring mechanism 300 are separated, after stirring is completed, clean water can be directly added and preliminarily cleaned through the stirring mechanism 300. By removing the loading component transported by the feeding mechanism, cleaning can be carried out again. The stirring mechanism 300 can replace the stirring part 323, so as to better clean the loading component transported by the feeding mechanism.
