Description

Technical Field

[0001] This utility model relates to the field of silicon-carbon anode composite material preparation technology, specifically a magnetic stirrer for preparing silicon-carbon anode composite materials. Background Technology

[0002] Silicon-carbon anode composite materials are typically prepared using methods such as mechanical ball milling, chemical vapor deposition, sol-gel, and electrospinning. By controlling the silicon particle size, rationally selecting and designing the carbon matrix, optimizing the silicon-to-carbon ratio, and ensuring the uniformity and integrity of the coating layer, silicon and carbon source materials are combined to obtain anode materials with high specific capacity, good conductivity, and cycle stability, thus meeting the demand for high-performance anode materials in energy storage devices such as lithium-ion batteries.

[0003] An investigation revealed that a Chinese utility model patent (CN209597072U) discloses a magnetic stirrer for preparing silicon-carbon anode composite materials. The stirrer includes a stirring chamber with symmetrically arranged heaters at the bottom. A heat-conducting plate covers the heaters, and a heat-conducting liquid fills the space between the heaters and the heat-conducting plate. A temperature measuring rod is installed on the outer wall of the stirring chamber, and a heater switch is located below the temperature measuring rod. The stirring chamber is mounted on top of a magnetic disk, and a magnet is installed at the center of the disk. A motor is fixedly connected to the bottom of the magnet, and a motor switch is electrically connected to the motor. A stir bar that cooperates with the magnet is installed inside the stirring chamber. An inclined partition is provided on the inner wall of the stirring chamber, and the stir bar has a main stirring rod and a secondary stirring rod. This utility model achieves uniform mixing and high-quality stirring of the silicon-carbon anode composite material; it saves stirring time and improves stirring efficiency.

[0004] The aforementioned patent is not very convenient for users. When the internal magnets degrade, they cannot be replaced quickly, requiring the entire stirrer to be replaced. This reduces the overall lifespan of the magnetic stirrer, increases the cost during operation, and is not conducive to the long-term use of the magnetic stirrer.

[0005] Therefore, this invention provides a magnetic stirrer for the preparation of silicon-carbon anode composite materials to solve the above problems. Utility Model Content

[0018] This invention provides a magnetic stirrer for the preparation of silicon-carbon anode composite materials. By setting an electric push rod, top plate, bearing, stirring column and metal stirring block, the stirring component is connected to the whole, which avoids the loss of the stirring component, improves the service life of the stirring component and is conducive to the long-term use of the stirrer.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 The present invention provides a technical solution: a magnetic stirrer for preparing silicon-carbon negative electrode composite material, comprising a workbench 1, a power supply battery 2 fixedly connected inside the workbench 1, a charging interface 3 fixedly connected to one side of the power supply battery 2, a rear baffle 4 fixedly connected to one side of the charging interface 3, a stirring motor 5 fixedly connected inside the workbench 1, a rotating plate 6 fixedly connected to the output shaft of the stirring motor 5 through a coupling, and a threaded strong magnetic block 7 rotatably connected to the top of the rotating plate 6.

[0029] A frame 8 is fixedly connected to the top of the workbench 1. A movable block 9 is movably connected inside the frame 8. An inner spring 10 is fixedly connected to one side of the movable block 9. A hollow frame 11 is fixedly connected to one end of the inner spring 10. A pad frame 12 is fixedly connected to one side of the hollow frame 11. A non-metallic mixing frame 13 is movably connected to the top of the pad frame 12. This makes the magnetic stirrer used for the preparation of silicon-carbon negative electrode composite materials more convenient to use. It allows for quick replacement of the internal magnetic blocks after magnetic degradation, eliminating the need to replace the entire stirrer. This extends the overall service life of the magnetic stirrer, reduces the cost required during operation, and facilitates the long-term use of the stirrer.

[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: an electric push rod 14 is fixedly connected to the top of the workbench 1, and the height of the electric push rod 14 is greater than the sum of the heights of the pad frame 12 and the non-metallic mixing frame 13, so as to facilitate the height of the connecting parts. A top plate 15 is fixedly connected to the top of the electric push rod 14, and a bearing 16 is fixedly connected inside the top plate 15, so that the connecting parts can rotate freely. A stirring column 17 is fixedly connected to the inner wall of the bearing 16, and a metal stirring block 18 is fixedly connected to the bottom end of the stirring column 17, so as to facilitate the stirring and mixing of the materials in the non-metallic mixing frame 13.

[0031] The bottom of the workbench 1 is fixedly connected to an electric lifting base column 19, and there are four electric lifting base columns 19, which can adjust the overall working height of the structure. The bottom end of the electric lifting base column 19 is fixedly connected to a base 20, and the bottom area of ​​the electric lifting base column 19 is smaller than the bottom area of ​​the base 20, which can provide stable support for the overall structure.

[0032] like Figure 1-5 As shown, when a user needs to use a magnetic stirrer for preparing silicon-carbon negative electrode composite materials, the material to be mixed is placed upside down inside the non-metallic mixing frame 13. The electric push rod 14 retracts, causing the metal stirring block 18 to be located at the bottom of the non-metallic mixing frame 13. At this time, the power supply battery 2 works, causing the stirring motor 5 to work. The output shaft of the stirring motor 5 rotates, causing the rotating plate 6 to drive the threaded strong magnetic block 7 to rotate. Due to the magnetic force, the metal stirring block 18 completes the mixing work inside the non-metallic mixing frame 13. If the threaded strong magnetic block 7 needs to be replaced, the electric push rod 14 extends, pressing the movable locking block 9, causing the inner spring 10 to be compressed and contracted, thereby causing the movable locking block 9 to retract inside the hollow frame 11. At this time, the pad frame 12 is removed, the threaded strong magnetic block 7 is rotated and removed, and the new threaded strong magnetic block 7 is rotated and locked on the top of the rotating plate 6. The movable locking block 9 is aligned with the locking frame 8 and pressed down, so that the movable locking block 9 completes the engagement with the locking frame 8, thereby locking the position of the pad frame 12.
