Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery recycling devices, specifically a fireproof stacking frame for recycling new energy lithium batteries. Background Technology

[0002] New energy lithium batteries are batteries that use lithium as the active material. They have advantages such as high energy density, high voltage, and environmental friendliness, and are widely used in electric vehicles and energy storage systems. Types of new energy lithium batteries include lithium-ion batteries, lithium polymer batteries, and solid-state lithium batteries. Each type has different electrochemical performance and packaging methods. Lithium-ion batteries are currently the most widely used new energy lithium batteries, with high voltage and energy density, long cycle life, and high safety, but they are also more expensive. Lithium polymer batteries are a new type of battery that uses polymers as electrolytes, offering high safety and designability, but with relatively lower energy density. Solid-state lithium batteries use solid electrolytes instead of traditional liquid electrolytes, resulting in higher energy density, better mechanical properties, and less environmental pollution risk, but their manufacturing cost is currently high. New energy lithium battery recycling refers to the process of recycling, processing, and reusing used or retired lithium-ion batteries. Lithium-ion batteries contain harmful substances such as heavy metals and organic matter, which can pollute the environment if not properly handled. Therefore, new energy lithium battery recycling is a crucial step. During recycling, lithium batteries need to be stacked together for temporary storage, awaiting collection; this requires the use of stacking devices.

[0003] Most of the stacking frames currently available for recycling new energy lithium batteries have the following problems during use:

[0004] Traditional stacking frames for recycling new energy lithium batteries have safety hazards. In actual use, if a fire occurs in the surrounding environment, the fire will spread to the lithium batteries themselves, as the lithium batteries themselves do not have fire-resistant properties. Furthermore, in actual use, lithium batteries vary in size, making it difficult to secure them according to their size after recycling. This causes the lithium batteries to shake when moved, and in severe cases, the stacked lithium batteries may even fall off, indicating a lack of stability. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a fireproof stacking frame for recycling new energy lithium batteries.

The first flame-retardant shell rotates via a first rotating shaft, and the second flame-retardant shell rotates via a second rotating shaft. The first and second flame-retardant shells surround the outside of the lithium battery shell. When a fire occurs in the environment surrounding the lithium battery shell, the first and second flame-retardant shells themselves contain flame-retardant materials, achieving a fire-retardant function and improving safety performance.

The recycled lithium battery shells can be placed on the top of the stacking plate. The first flame-retardant shell rotates through the first rotating shaft and the second flame-retardant shell rotates through the second rotating shaft, so that the first flame-retardant shell and the second flame-retardant shell surround the outside of the lithium battery shell.

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a fireproof stacking frame for recycling new energy lithium batteries, including a stacking frame shell 1, a flame-retardant plate 3 connected to the top of the stacking frame shell 1, a first rotating shaft 5 and a second rotating shaft 7 connected to the outside of the flame-retardant plate 3 respectively, a first flame-retardant shell 4 connected to the outside of the first rotating shaft 5, and a second flame-retardant shell 6 connected to the outside of the second rotating shaft 7. Fixing slots 13 are provided inside both the flame-retardant plate 3 and the second flame-retardant shell 6, and the fixing slots 13 are symmetrically distributed. A fixing block 9 is connected to the outside of the first flame-retardant shell 4, and the fixing block 9 is connected to the inside of the fixing slot 13 by insertion.

[0026] The recycled lithium battery casings 10 can be placed on top of the stacking plate 11. The first flame-retardant casing 4 rotates via the first rotating shaft 5, and the second flame-retardant casing 6 rotates via the second rotating shaft 7, so that the first flame-retardant casing 4 and the second flame-retardant casing 6 surround the outside of the lithium battery casing 10. When a fire occurs in the environment around the lithium battery casing 10, the first flame-retardant casing 4 and the second flame-retardant casing 6 themselves have flame-retardant materials, thereby achieving a fire-retardant function. In practical applications, this can prevent the flame from igniting the lithium battery casing 10 itself, thus improving safety performance.

[0027] The flame-retardant plate 3 has a stacking plate 11 inside. The top of the stacking plate 11 is fixedly connected to the clamping frame 14. The top of the flame-retardant plate 3 has a battery casing 10. The clamping frame 14 clamps the outer wall of the battery casing 10, so that the lithium battery casing 10 can be placed on the top of the stacking plate 11. The clamping plate clamps the lithium battery casing 10, and the magnetic block 17 will be attracted and fixed inside the inner groove 15. In this way, when the recycled lithium battery casing 10 is moved, the lithium battery will not shake. In severe cases, the stacked lithium batteries may even fall off, thereby improving the stability during use.

[0028] The rubber pillars 12 are connected to the inside of the fixing slot 13 by adhesive bonding. The rubber pillars 12 are symmetrically distributed and block the outside of the fixing block 9. After the first flame-retardant shell 4 is fixed by rotation through the first rotating shaft 5, the fixing block 9 is simultaneously fixed inside the fixing slot 13, while the rubber pillars 12 block the outside of the fixing block 9, thus preventing the first flame-retardant shell 4 from becoming loose.

[0029] The flame-retardant plate 3 is internally connected to a slide rail 8, and the bottom of the stacking plate 11 is connected to a slider 16. The slider 16 is movably connected inside the slide rail 8. When the lithium battery casing 10 is placed and removed, the stacking plate 11 can be pulled out, and the slider 16 slides inside the slide rail 8 at the same time, which can support the pulled-out stacking plate 11.

[0030] The clamping frame 14 has an inner groove 15 inside, and the outer wall of the battery casing 10 is connected to a magnetic block 17. The magnetic block 17 is connected to the inside of the inner groove 15 by adsorption. When the lithium battery casing 10 is installed on the top of the stacking plate 11, the magnetic block 17 is simultaneously adsorbed and fixed inside the inner groove 15, which again provides support for the lithium battery casing 10.

[0031] The bottom of the stacking frame shell 1 is connected to the moving wheels 18, which are evenly distributed. The top of the flame-retardant plate 3 is connected to the stacking top 2. Using the moving wheels 18 at the bottom, the stacking frame shell 1 can be moved to the position where it is needed.

[0032] The working principle of this fireproof stacking frame for recycling new energy lithium batteries is as follows: First, the stacking plate 11 is pulled out, and the slider 16 simultaneously slides inside the slide rail 8, providing support for the pulled-out stacking plate 11. Then, the lithium battery casing 10 is placed on top of the stacking plate 11, and the magnetic block 17 is fixed by adsorption inside the inner groove 15. This prevents the lithium battery from shaking when moving the recycled lithium battery casing 10, and in severe cases, prevents the stacked lithium batteries from falling off. This improves stability during use. Then, the stacking plate 11 is pushed into the interior of the stacking frame housing 1. The first flame-retardant housing 4 is closed by rotating the first pivot 5, and the second flame-retardant housing 6 is closed by rotating the second pivot 7. The fixing block 9 is inserted into the interior of the fixing slot 13, while the rubber pillar 12 will block the outside of the fixing block 9. When a fire occurs in the environment around the lithium battery housing 10, the first flame-retardant housing 4 and the second flame-retardant housing 6 themselves have flame-retardant materials, thereby achieving the fire-retardant function. In practical applications, this can prevent the flame from igniting the lithium battery housing 10 itself, thus improving safety performance.

[0033] This utility model comprises: 1. a stacking frame shell; 2. a stacking top; 3. a flame-retardant plate; 4. a first flame-retardant shell; 5. a first rotating shaft; 6. a second flame-retardant shell; 7. a second rotating shaft; 8. a slide rail; 9. a fixing block; 10. a battery shell; 11. a stacking plate; 12. a rubber pillar; 13. a fixing slot; 14. a clamping frame; 15. an inner groove; 16. a slider; 17. a magnet; and 18. a moving wheel. All components are general standard parts or parts known to those skilled in the art, and their structures and principles can be obtained by those skilled in the art through technical manuals or conventional experimental methods. The problem this utility model solves is that traditional stacking frames for recycling new energy lithium batteries pose a safety hazard when a fire breaks out in the surrounding environment. The lithium batteries themselves lack fire-resistant properties. Furthermore, traditional stacking frames for recycling lithium batteries come in various sizes, making it difficult to secure them properly after recycling. This leads to shaking when moving the recycled batteries, and in severe cases, the stacked batteries may even become unstable. The previous invention addressed the issue of battery casings falling off and lacking stability by combining the aforementioned components. A first flame-retardant shell and a second flame-retardant shell are respectively provided on the top of the stacking frame. Recycled lithium battery casings can be placed on top of the stacking plate. The first flame-retardant shell rotates via a first shaft, and the second flame-retardant shell rotates via a second shaft, thus surrounding the lithium battery casing. When a fire occurs in the surrounding environment, the flame-retardant shells themselves, being made of flame-retardant material, achieve a fire-resistant function, preventing the flame from igniting the lithium battery casing itself and improving safety. A clamping frame is provided on top of the stacking plate, with an inner groove inside the clamping frame and a magnetic block on the outside of the lithium battery casing. The lithium battery casing can be placed on top of the stacking plate, clamped by the clamping plate, and fixed by the magnetic block adsorbed inside the inner groove. This prevents the lithium battery from shaking when moving the recycled casing, and in severe cases, the stacked lithium batteries may even fall off, thus improving stability during use.
