Description

Technical Field

[0001] This utility model relates to the field of lithium battery production, and in particular to a demagnetizing device. Background Technology

[0002] Compared to traditional batteries, lithium batteries have advantages such as small size, light weight, high energy density, high operating voltage, long cycle life, fast charging speed, and no memory effect. They also do not contain heavy metals such as lead and cadmium, and are non-toxic and pollution-free. These numerous advantages make lithium batteries stand out in the market. The energy density and safety performance of lithium battery raw materials are the decisive factors in the electrochemical performance of lithium batteries, playing a leading role and therefore being the most important. The content of magnetic foreign matter is one of the important indicators for evaluating battery raw materials. The production of lithium battery raw materials typically involves powdered materials. Rusting of equipment parts and tools in contact with the powder, as well as inherent material wear, can introduce magnetic impurities. Impurities and dust that are not in direct contact with the materials can also float into the materials due to airflow in the workshop. These metallic impurities can affect the discharge process of lithium batteries, leading to battery safety issues. To ensure the stability of lithium battery performance, battery manufacturers have very strict requirements on the content of magnetic foreign matter in lithium battery raw materials. Current material feeding and demagnetizing devices face a serious problem after long-term high-intensity use: due to the strong impact force generated during the material feeding process, the core component of these devices—the magnetic rod—often suffers varying degrees of damage. Specifically, this impact force can cause the magnetic rod to bend, break, or even detach. These problems not only severely affect the normal operation and demagnetization effect of the demagnetizing device but also pose significant safety hazards. Therefore, providing a highly safe and stable feeding demagnetizing device is the research direction of this utility model. Utility Model Content

[0003] The purpose of this utility model is to provide a demagnetizing device that effectively supports the magnetic rod from both ends and the middle through a fixing mechanism and a fixing plate, thereby preventing the magnetic rod from falling off or bending, and improving the safety of demagnetization.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model discloses a demagnetizing device, including a four-way pipe fitting. The four-way pipe fitting includes a feeding pipe and branch pipes located on both sides of the feeding pipe. Multiple magnetic rods are inserted through the branch pipes, and a fixing mechanism for fixing the magnetic rods is provided in the branch pipes. The four-way pipe fitting also includes a fixing plate. All magnetic rods are arranged through the fixing plate.

[0006] A further embodiment: The fixing mechanism includes a blind plate sealed on the branch pipe and a support seat located inside the blind plate for accommodating the end of the magnetic rod.

[0007] A further embodiment: the fixing mechanism also includes fasteners located on the outer periphery of the blind plate for connecting the blind plate and the branch pipe.

[0008] A further option: the fastener is a clamp.

[0009] A further solution: The blind plate has a through hole, which is concentrically arranged with the support base.

[0010] A further solution: a handle is provided on the outside of the blind plate.

[0011] A further solution: the support base and the magnetic rod are connected by a thread.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention provides effective support for the magnetic rod through a fixing mechanism and a fixing plate, effectively preventing the magnetic rod from loosening due to vibration or impact during use, and ensuring the continuity and stability of the demagnetization process. The fixing mechanism supports both ends of the magnetic rod, providing stable support points to prevent the magnetic rod from falling off due to uneven force during use. Simultaneously, the fixing plate supports the middle section of the magnetic rod, providing additional physical support. By evenly distributing the force, it reduces the deformation of the magnetic rod during the impact of feeding, thereby reducing the risk of the magnetic rod bending.

[0014] By incorporating a portable handle for easy installation and removal, operators can quickly push or pull the blind flange into or out of the pre-installed position on the branch pipe without the need for additional lifting equipment or complex procedures. This design significantly reduces installation and disassembly time and improves equipment maintenance efficiency. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Please see Figure 1-2 In this embodiment, a demagnetizing device includes a four-way fitting 1, which includes a feed pipe 11 and branch pipes 12 located on both sides of the feed pipe 11. Multiple magnetic rods 2 are transversely inserted into the branch pipes 11, and fixing mechanisms 3 for fixing the magnetic rods 2 are provided in the branch pipes 12. A fixing plate 4 is also provided in the four-way fitting 1. All magnetic rods 2 pass through the fixing plate 4. The fixing mechanism 3 supports both ends of the magnetic rods 2, providing stable support points to prevent the magnetic rods 2 from falling off due to uneven force during use. Simultaneously, the fixing plate 4 supports the middle section of the magnetic rods 2, providing additional physical support. By evenly distributing the force, it reduces the deformation of the magnetic rods during the feed impact, thereby reducing the risk of bending of the magnetic rods 2.

[0021] Furthermore, the fixing mechanism 3 includes a blind flange 31 sealed on the branch pipe 12 and a support seat 32 located inside the blind flange 31 for accommodating the end of the magnetic rod 2. The blind flange 31 and the support seat 32 provide effective support for the end of the magnetic rod 2, enhancing the installation stability of the magnetic rod 2.

[0022] Furthermore, the fixing mechanism 3 also includes fasteners 33 located on the outer periphery of the blind flange 31 for connecting the blind flange 31 and the branch pipe 12. These fasteners 33 are clamps. The clamps not only connect the blind flange 31 and the branch pipe 12, but also, through their tightening action, fix the device in the reserved position in the piping system, ensuring that the fixing mechanism 3 will not shift or loosen due to the impact or vibration of the material during the material feeding process.

[0023] Furthermore, a through hole 311 is provided on the blind plate 31, which is concentrically arranged with the support base 32. This through hole is used to check whether the magnetic rod 2 is installed in place. The support base 32 of the fixing mechanism 3 on one side is threadedly connected to the magnetic rod 2, while the other side is connected by a transition fit, with a slight gap between the support base 32 and the magnetic rod 2.

[0024] Furthermore, a handle 5 is provided on the outside of the blind plate 31. The handle 5 simplifies the installation and disassembly process of the magnetic rod 2, and improves the convenience and safety of operation.

[0025] During installation, the threaded end of the magnetic rod 2 is first installed on the corresponding support 32. Then, the magnetic rod 2 and the blind plate 31 on that side are inserted into the branch pipe 12 and the clamp on that side is fixed. Then, the blind plate 31 on the other side is pushed into the branch pipe 2 on the other side so that the support 32 and the magnetic rod 2 correspond one-to-one. Finally, the clamp is pre-tightened.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
