Description

Technical Field

[0001] The utility model belongs to the field of collecting devices, in particular to a track chain magnetic metal particle collecting device. Background Art

[0002] As the core energy source of modern electronic devices, lithium batteries have become the research focus in the field of battery technology due to their high energy density, long cycle life and low environmental impact. As one of the positive electrode materials, lithium iron phosphate (LiFePO4) is widely used in various types of lithium batteries due to its excellent volume expansion performance, high cycle stability and high safety standards. These characteristics make lithium iron phosphate one of the most successful commercial positive electrode materials and provide an important material foundation for the development of the lithium battery industry.

[0003] Although lithium iron phosphate materials have many advantages, if there are magnetic metal particles impurities in lithium iron phosphate, these impurities will not only pierce the battery separator, accelerate the self-discharge of the battery cell, but also may cause safety problems of the battery cell. Therefore, the magnetic metal particles in lithium iron phosphate, the positive electrode material of lithium-ion batteries, are the key factors affecting the safety characteristics of the product. How to prevent and control magnetic metal particles in the preparation process of lithium iron phosphate is crucial.

[0004] In the current lithium iron phosphate feeding process, track chains are used as transmission components. The metal chains are exposed and constantly rub against the tracks. The space between the two sections of the track chains is hollow, and the metal particles generated by the friction cause a large number of metal particles to be carried to the gap between the two sections of the track and spread to the entire environment.

[0005] Based on this, there is an urgent need for a magnetic metal particle collection device to match the lithium iron phosphate feeding process, so as to automatically collect the magnetic metal particles that fall into the gap between the two sections of the track, and prevent the magnetic metal particles from diffusing into the product and causing product safety hazards.

[0009] Furthermore, the box body adopted by the magnetic metal particle collection device can be a square structure with top and bottom penetration, and the metal particle collection device further includes a collection box bottom box located at the bottom end of the box body and detachably connected thereto.

[0010] Furthermore, the collection box bottom box and the box body adopted by the magnetic metal particle collection device are detachably connected by a buckle.

[0011] Furthermore, the card slots extending inward on the front and rear sides of the box body adopted by the magnetic metal particle collection device are U-shaped card slot structures.

[0012] Furthermore, several docking bumps extend downward at the bottom end of the box body adopted by the magnetic metal particle collection device, and grooves corresponding to the several docking bumps are formed on the collection box bottom box to achieve installation limit.

[0017] Figure 3 is a three-dimensional Figure 2 ;

[0018] Figure 4 is a schematic structural diagram of the magnetic metal particle collection device of the present utility model assembled on adjacent tracks. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] As Figures 1 to 4 shown, the magnetic metal particle collection device of the present utility model is mainly applied to automatically collect the magnetic metal particles generated by the continuous friction and wear of the chain on the track 1 when transporting lithium iron phosphate raw materials by the track 1 and prevent them from spreading around. Specifically, it is applied between adjacent tracks 1 and is located below adjacent tracks 1 to collect the generated and dropped magnetic metal particles.

[0021] The magnetic metal particle collection device includes a box body 2 for collecting magnetic metal particles on the track 1. The box body 2 can be a square structure with a bottom plate, or the box body 2 can be a square structure with only four side surfaces that are open at both the top and bottom and penetrate each other. When the box body 2 is a square structure with only four side surfaces, in order to effectively collect magnetic metal particles, a collection box bottom box 5 can be detachably connected to the bottom end of the box body 2. The setting of this structure enables convenient cleaning of the magnetic metal particle collection device. When cleaning is required, only the collection box bottom box 5 needs to be conveniently disassembled, rather than disassembling the entire magnetic metal particle collection device spanning adjacent tracks 1, which improves the convenience of using the magnetic metal particle collection device. The detachable connection between the collection box bottom box 5 and the box body 2 can be directly set through a lock catch 6, or some conventional connection structures in the art such as a bolt can be used. The present utility model does not make excessive limitations as long as the convenient connection between the two can be achieved. In addition, in order to further reflect the quickness of the installation of the collection box bottom box 5 and the box body 2, a plug-in limit structure for the two can be set. That is, several docking protrusions can be extended downward from the bottom end of the box body 2, and corresponding grooves for cooperating with the several docking protrusions are opened on the collection box bottom box 5 to achieve installation limitation.

[0022] The connection of the magnetic metal particle collection device of the present utility model to the adjacent track 1 is achieved through the card slots 4 extending inwardly on both the front and rear sides of the box body 2. Correspondingly, a connecting member matching the connection of the card slot 4 can be set on the track 1 to achieve the stable connection between the two. For example, it can be directly connected by bolts. The card slot 4 can be set in a U-shaped structure. On the left and right sides of the box body 2, baffles 3 are also extended upward. The setting of the baffles 3 enables the two baffles 3 to be located on the left and right sides of the adjacent track 1 when the magnetic metal particle collection device spans between adjacent tracks 1, so as to effectively block the diffusion of the magnetic metal particles dropped between the chains of the adjacent tracks 1. The baffle 3 is located at the middle position of the box body 2, and its length can be greater than or equal to the distance between adjacent tracks 1.

[0023] Based on the above, the magnetic metal particle collection device is horizontally arranged between adjacent tracks and located below them, capable of automatically collecting the magnetic metal particles generated by the wear of the chain on the tracks, thereby effectively preventing the diffusion of magnetic metal particles into the product and avoiding potential safety hazards; at the same time, the magnetic metal particle collection device can effectively prevent the magnetic metal particles worn from the chain from spreading around.
