Description

Technical Field

[0001] This utility model relates to the field of waste battery recycling technology, specifically to a crushing drum mechanism for recycling and processing waste battery electrode sheets. Background Technology

[0002] Recycling and processing waste battery electrodes is a crucial step in achieving resource recycling and environmental protection. Common methods for recycling waste batteries include physical and chemical methods. Physical methods include crushing and screening: crushing waste battery electrodes into smaller pieces, then separating materials of different sizes using screening equipment. Airflow separation: using aerodynamic principles to separate metal powders from non-metal powders. Gravity separation: separating copper particles, aluminum particles, etc., based on differences in specific gravity.

[0003] Crushing and processing waste battery electrode sheets is a crucial step in the waste battery recycling process. Its purpose is to break the electrode sheets into smaller particles for subsequent separation and extraction. Existing waste battery electrode sheet crushing and recycling processes include:

[0004] 1. Discharge treatment: Short-circuit the positive and negative terminals of the battery to allow it to deplete naturally, or use specialized discharge equipment to release the charge through a chemical reaction. This ensures that any residual charge in the battery is completely released, preventing dangerous situations such as short circuits and fires during subsequent processing.

[0005] 2. Disassembly: Disassemble the battery casing to separate components such as electrodes, electrolyte, and separator. For small batteries, disassembly can be done manually. For large batteries, automated disassembly equipment can be used to improve efficiency and safety.

[0006] 3. Crushing: The electrode sheets are crushed into smaller particles to facilitate subsequent separation and extraction. Jaw crushers or hammer crushers are used to crush the electrode sheets into larger blocks. Ball mills, vibratory mills, and other equipment are used to further crush the blocky material into finer particles.

[0007] 4. Screening: Separate the crushed materials according to particle size for easier subsequent processing. Use a vibrating screen to screen the materials according to their particle size. Alternatively, use airflow to separate light and heavy materials.

[0008] 5. Magnetic separation: Using a magnetic separator, ferromagnetic materials are separated from the material. Magnetic separation can also be performed in liquids and is suitable for separating fine particles. It utilizes differences in magnetic properties to separate ferromagnetic materials, such as iron filings.

[0009] 6. Gravity separation: Utilizing the vibration of a shaking table to separate materials of different densities into strata. Alternatively, using the flow of water in a spiral chute to separate materials of different densities. Based on the density differences of the materials, metal particles such as copper and aluminum can be separated.

[0010] In the existing technology, manual disassembly of battery electrodes is inefficient, while mechanical disassembly mixes the electrodes with other materials, making it impossible to directly separate the waste battery electrodes. Further processing is required, resulting in low processing efficiency. Utility Model Content

[0011] The technical problem solved by this utility model is that the equipment for disassembling battery electrodes in the prior art cannot directly separate the waste battery electrodes, and other processes are required afterward, resulting in low processing efficiency.

[0012] The objective of this utility model can be achieved through the following technical solutions:

[0013] A crushing drum mechanism for recycling and processing waste battery electrode sheets includes:

[0014] A cylindrical body, wherein the cylindrical body is provided with an opening for taking out and putting in, and at least one area of ​​its side wall is hollowed out;

[0015] A cutting element, comprising a cutting end and a tail end, wherein the size of the cutting end is smaller than the size of the tail end, and a plurality of cutting elements are spaced apart on the inner wall of the cylinder;

[0016] A support structure, wherein the cylindrical body is rotatably mounted on the support structure;

[0017] A drive assembly for driving the cylinder to rotate.

[0018] In one embodiment of this utility model: the cylinder is disposed on a receiving tank, the receiving tank is used to store the dissolving liquid or the cleaning liquid, and the bottom end of the cylinder is located below the liquid surface in the receiving tank.

[0019] In one embodiment of this utility model: the cutting components include several groups, which are spaced apart around the cylinder, and multiple cutting components in the same group are spaced apart along the axial direction of the cylinder.

[0020] In one embodiment of this utility model: the support structure is fixedly mounted on the first base, one end of the first base near the pick-up / placement port is rotatably connected to the second base, and the other end is provided with a lifting drive structure.

[0021] In one embodiment of this utility model: a receiving component is provided below the cylinder.

[0022] In one embodiment of this utility model: the receiving component includes a first receiving layer and a second receiving layer, with the first receiving layer located on top and hollowed out.

[0023] In one embodiment of this utility model: the inner wall of the cylinder is provided with an inclined guide portion, and the size of the guide portion at one end near the hollow area of ​​the cylinder is smaller than the size of the other end.

[0024] In one embodiment of this utility model: a central column is further provided, the central column is fixedly mounted on a fixed base, and a lever is fixedly mounted on the part of the central column located inside the cylinder, the lever being arranged radially along the cylinder.

[0025] In one embodiment of this utility model, the lever and the cutting element are arranged alternately.

[0026] In one embodiment of this utility model: the fixed base is provided with a power source for driving the central column to rotate.

[0027] The crushing drum mechanism for recycling and processing waste battery electrode sheets according to this utility model has at least one of the following technical effects:

[0028] In use, waste batteries are placed inside the cylinder, which is then rotated to tumble the batteries. During this process, as the batteries impact the cutting end, the cutting end of the cutting component creates an opening in the battery casing (the cutting component can be smaller than the battery itself, allowing for separation of the internal powder from the electrodes while maintaining the integrity of the electrodes for easier screening). As the tumbling continues, the internal powder separates from the external electrodes. The impact of the battery impacting the rear end of the cutting component further promotes the detachment of the internal powder. The separated powder falls through the cylinder's perforations onto the receiving component during the tumbling process. Several cutting components can be arranged in different directions, allowing the cylinder to rotate continuously in the same direction. Alternatively, the cutting components can be arranged in the same direction, requiring the cylinder to alternate between forward and reverse rotation. During forward rotation, the cutting end creates an opening; during tumbling, the batteries impact the rear end of the cutting end, promoting separation. After a certain period, once the electrodes are separated, the receiving port is opened to discharge the waste battery electrodes. Furthermore, a central column with a lever is provided. The lever can be staggered with the cutting component, and the outer end of the lever (the end closest to the cylinder) can be staggered or not staggered with the inner end of the cutting component. In this way, the lever can move and push the waste battery during rotation, ensuring the cutting component effectively cuts and opens the waste battery. When the waste battery contacts the rear end of the cutting component, it promotes the deformation of the opened waste battery, making it easier for the powder inside to be released. This application, by setting a cutting component inside a rotatable cylinder and hollowing out the cylinder, can open the waste battery during rotation, achieving automatic separation of the waste battery electrodes from their internal fragments, improving the efficiency of waste battery electrode crushing and recycling, and simplifying subsequent processing.

[0029] When the cylinder is placed on the receiving tank, it works in conjunction with the dissolving or cleaning solution in the receiving tank to simultaneously achieve waste battery cutting and partial component dissolution and recovery or electrode cleaning, thereby improving the efficiency of waste battery processing.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] Example 1

[0039] Please see Figure 1 This embodiment provides a crushing rotary drum mechanism for recycling waste battery electrodes, including a cylinder 1, which can be a cylindrical structure. The cylinder 1 is provided with a loading / unloading port for loading and unloading materials. At least one loading / unloading port can be provided, located on the side or at the end, and a corresponding sealing plate can be provided as a door. As an example, the loading / unloading port is located on the side of the cylinder 1 and is equipped with a locking / unlocking door, which can be locked by a snap-fit ​​structure. The outer circumference of the cylinder 1 is hollowed out to separate the electrodes from the granular fragments. The inner wall of the cylinder 1 can be provided with a cutting element 2, which can cut the waste batteries inside as the cylinder 1 rotates, separating the electrodes.

[0040] The rotating drum can be installed within the receiving tank 10 structure. For example, rotating shafts are installed at both ends of the drum, and these shafts are rotatably mounted on the frame of the receiving tank 10. The bottom of the drum is below the liquid level within the receiving tank 10. The rotation of the drum 1 can be driven by a motor (drive assembly 5) located at the end of the rotating shaft. The receiving tank 10 is used to store a dissolving solution or a cleaning solution. The dissolving solution can be used to dissolve impurities in the material or to separate materials such as aluminum foil and iron ions from the material. Water can also be used as the washing solution, which cleans the material in the drum 1 as it tumbles. A shield 11 can be installed on the receiving tank 10. The shield 11 is rotatably connected to the receiving tank 10. When needed, the shield 11 can be flipped above the drum 1 to prevent material splashing, thus avoiding safety issues and pollution at the work site. The receiving tank 10 can be connected to a water circulation assembly 12, which may include a pipeline structure, a filter assembly, and a water pump. The water circulation component 12 can circulate the washing solution, removing any impurities that may be present in the water and facilitating its reuse. The bottom of the receiving tank 10 can be configured as a funnel structure, with an outlet and valve at the bottom. Alternatively, it can be connected to a filter press via pipelines and a water pump to filter and recover dissolved components from the solution. The filter press outlet can also be connected to the water circulation component 12 to recycle the filtered water.

[0041] Example 2

[0042] Please see Figure 2-3This embodiment provides a crushing drum mechanism for recycling waste battery electrode sheets, including a drum body 1, a cutting component 2, a receiving component 3, a supporting structure 4, and a driving assembly 5. The drum body 1 can be a cylindrical structure. The drum body 1 is provided with an inlet / outlet for loading and unloading materials. The inlet / outlet can be a single point, located on the side or at the end, and equipped with a corresponding sealing plate. As an example, the inlet / outlet of the drum body 1 is located at one end and is equipped with a sealing door. The inlet / outlet can also be multiple, with left and right inlets and outlets, the specific locations of which can be selected as needed. At least one area of ​​the side wall (i.e., the outer circular surface) of the drum body 1 is hollowed out to allow direct screening and separation of the internal waste material after the waste batteries are cut.

[0043] Please see Figure 2-3 In one embodiment of this utility model, the cylinder 1 is rotatably mounted on the support structure 4 and driven to rotate by the drive assembly 5. Specifically, the support mechanism can be an arc-shaped support base to support the cylinder 1 and keep it stable. Alternatively, it can be a track-type structure with matching slide rails on the cylinder 1 that movably engage with the support structure 4. Another option is to have a rotating shaft at each end of the cylinder 1, and then rotatably mount the shafts on the base structure or frame structure. The drive assembly 5 can include a power source, such as a servo motor, whose output end, such as a gear or pulley, drives a driven component on the cylinder 1, such as a gear ring, gear, or pulley. When it is a gear, it is meshed; when it is a pulley, it is driven by a belt. When the cylinder 1 is supported at both ends by rotating shafts, the rotating shafts can also be directly driven to rotate by the motor.

[0044] Please see Figure 2-3 In one embodiment of this utility model, the cutting element 2 includes a cutting end and a tail end, the size of which is smaller than that of the tail end. The cutting end is used to cut an opening in the waste battery. Several cutting elements 2 are spaced apart on the inner wall of the cylinder 1. The distribution of the cutting elements 2 can be uneven or uniform. Specifically, the cutting elements 2 can include several groups, spaced apart around the cylinder 1, with multiple cutting elements 2 in the same group spaced apart along the axial direction of the cylinder 1. The spacing can be uniform or uneven, depending on the actual situation, to ensure the cutting effect.

[0045] Please see Figure 2-3In one embodiment of this utility model, the receiving member 3 is disposed below the hollowed-out area of ​​the cylinder 1; it is used to receive the separated fine fragments. The receiving member 3 can be a plate-shaped structure or a conveyor belt structure to directly transport the material out. As another example, the receiving member 3 includes a first receiving layer and a second receiving layer, with the first receiving layer located on top and hollowed out, which facilitates solid-liquid separation.

[0046] Please see Figure 2 In one embodiment of this utility model, the support structure 4 can be fixedly mounted on the first base 6. One end of the first base 6 near the loading / unloading port is rotatably connected to the second base 7, and the other end is provided with a lifting drive structure. The lifting drive can be a hydraulic mechanism, a linear motor, a screw linear drive structure, etc. When needed, the lifting drive structure can be used to drive one end of the cylinder 1 to lift and tilt it for more efficient material discharge.

[0047] Please see Figure 2-3 In one embodiment of this utility model, the inner wall of the cylinder 1 may be provided with an inclined guide portion. The size of the guide portion at one end near the hollow area of ​​the cylinder 1 is smaller than the size of the other end, so that the fine fragments at the bottom can be guided to the hollow area and screened out.

[0048] Please see Figure 3 In one embodiment of this utility model, a central column 8 is further provided, which is fixedly mounted on a fixed base. A lever 9 is fixedly mounted on the portion of the central column 8 located inside the cylinder 1, and the lever 9 is arranged radially along the cylinder 1. The cross-sectional shape of the lever 9 can be circular or square. The lever 9 is staggered with the cutting member 2. A power source for driving the central column 8 to rotate is provided on the fixed base. The power source is used to drive the central column 8 to rotate in the opposite direction to the cylinder 1.

[0049] The working principle of this embodiment:

[0050] Waste batteries are placed inside cylinder 1, and then cylinder 1 is driven to rotate, causing the waste batteries inside to tumble. During this process, when the waste batteries hit the cutting end, the cutting end of the cutting piece 2 makes an opening in the outer shell of the waste battery (the size of the cutting piece 2 can be smaller than the size of the waste battery, so that the opening can be made to separate the internal powder from the electrode sheet while maintaining the integrity of the electrode sheet, facilitating the screening process). As the tumbling continues, the internal powder is separated from the external electrode sheet. When the waste battery hits the rear end of the cutting piece 2, it is impacted, promoting the detachment of the internal powder. The separated powder falls from the drain hole of cylinder 1 onto the receiving piece 3 during the tumbling process. Several cutting pieces 2 can be arranged in different directions, so that cylinder 1 can be driven to rotate continuously in the same direction. Alternatively, the cutting pieces 2 can be arranged in the same direction, so that cylinder 1 needs to be driven to rotate in both directions alternately. During forward rotation, the opening is made through the cutting end; during tumbling, the waste battery hits the rear end of the cutting end, promoting separation. After a certain period of time, the electrode sheet separation is completed, and the waste battery electrode sheet is discharged from the pick-and-place port. Furthermore, a central column 8 with a lever 9 is provided. The lever 9 can be staggered with the cutting component 2. The outer end of the lever 9 (the end closer to the cylinder 1) can be staggered with or not staggered with the inner end of the cutting component 2. In this way, the lever 9 can move and push the waste battery during rotation, ensuring the cutting opening effect of the cutting component 2 on the waste battery. When the waste battery contacts the rear end of the cutting component 2, it can promote the deformation of the opened waste battery, which is more conducive to the release of its internal powder.

[0051] Example 3

[0052] Please see Figure 4 This embodiment is a combination of parts of Embodiment 1 and Embodiment 2. Rotating shafts are provided at both ends of the cylinder 1, and these shafts are rotatably mounted on a movable support 13 (which can be a frame structure) via support members. A motor for driving the rotation of the cylinder 1 is also connected to the movable support 13. Simultaneously, one end of the movable support 13 is rotatably mounted, and a power source can be provided to drive the rotation of the movable support 13. When it is necessary to cut and screen the waste batteries, the cylinder 1 is positioned on the right side (only with...) Figure 4 (For example) Located on a fixed support, with the receiving part 3 located below the fixed support, when it is necessary to immerse the cylinder 1 in liquid, the cylinder 1 can be flipped into the receiving tank 10 by flipping the movable support 13, which can clean the battery electrodes. Alternatively, after cleaning, it can be flipped to the right to turn over and air dry the internal materials.
