Description

Technical Field

[0001] The present invention relates to the technical field of battery recycling, and in particular to a battery cutting, separation and recycling device and method thereof. Background Art

[0002] A lead-acid battery is a type of storage battery whose electrodes are primarily made of lead and its oxides, and whose electrolyte is a sulfuric acid solution. When discharged, the positive electrode is primarily composed of lead dioxide, while the negative electrode is primarily composed of lead. When charged, both the positive and negative electrodes are primarily composed of lead sulfate. Currently, lead-acid batteries are widely used in automobiles and electric motorcycles. Due to my country's large vehicle population, recycling batteries from scrapped vehicles is an urgent issue. Recycled batteries are recycled and reused using resource-recycling methods.

[0003] The treatment of electrolyte in the recycling process is a core environmental protection and safety link. The disassembly of lead-acid batteries mostly adopts a cylinder-driven push plate combined with a fixed blade structure. The push plate pushes the battery toward the blade to cut the shell and allow the internal electrolyte to flow out. The electrolyte flows to the surface of the workbench during the cutting process. Although the workbench is usually designed as a tilted structure, some electrolyte still remains, which will cause long-term corrosion to the metal or plastic material of the workbench and affect the life of the equipment. During the resetting process, the push plate may carry the electrolyte to the non-cutting area, causing the electrolyte to diffuse. Summary of the Invention

[0004] The present invention overcomes the above-mentioned drawbacks and provides a battery cutting, separation and recovery device and method thereof. The present invention solves the technical problem that when disassembling lead-acid batteries, electrolyte remains on the workbench and is carried to the non-cutting area by the push plate, causing spread of contamination.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] Reference Figures 1 to 3This is the first embodiment of the present invention, which provides a battery cutting, separation and recycling device. The battery recycling method and device include a main assembly 100 and a workbench 101. A cylinder 102 is fixed to one side of the workbench 101. A push plate 103 is bolted to one side of the telescopic rod of the cylinder 102. The push plate 103 is used to push the battery to move. A blade 104 is provided on the workbench 101. The blade 104 is bolted to a mounting bracket fixed to the workbench 101. The push plate 103 pushes the battery toward the blade 104. The blade 104 cuts the battery shell and the electrolyte inside the battery flows out. This is the existing technology and will not be elaborated in detail in this solution. Those skilled in the art can clearly understand the working principle. A cutting table 105 is provided on one side of the workbench 101. The battery will be cut only after it is pushed onto the cutting table 105. There is a three-sided gap between the workbench 101 and the cutting table 105 to facilitate the electrolyte to flow out of the workbench. The cut battery shell is moved to the side auxiliary table 107, and the auxiliary table 107 is fixed to one side of the workbench 101.

[0032] The unloading assembly 200 is arranged on one side of the workbench 101 and includes a liquid barrel 201. The liquid barrel 201 has good corrosion resistance. A unloading piece 202 is provided on one side of the workbench 101. The setting of the unloading piece 202 facilitates the unloading of the cut batteries and facilitates the diversion of the electrolyte remaining on the cutting table 105 to the liquid barrel 201. An auxiliary piece 203 is provided on one side of the cutting table 105. The setting of the auxiliary piece 203 ensures the smooth movement of the push plate 103 when pushing the battery.

[0033] The unloading member 202 includes a fixed column 2021 fixed on the cutting table 105, one end of the fixed column 2021 is connected to the workbench 101 by a bearing, the workbench 101 is provided with a chamber 101-1, the fixed column 2021 is connected to the inner wall bearing of the chamber 101-1, a worm wheel 2022 is fixed on the fixed column 2021, a worm 2023 is connected to the bearing in the chamber 101-1, the worm wheel 2022 is meshed with the worm 2023, and a rotating column is fixed to one side of the worm 2023 2024, the rotating column 2024 is used to drive the worm 2023 to rotate. When the rotating column 2024 drives the worm 2023 to rotate synchronously, it will drive the worm wheel 2022 and the fixed column 2021 to rotate, thereby rotating the cutting table 105 and changing its angle with the workbench 101. When the push plate 103 pushes the battery to be cut, the cutting table 105 and the workbench 101 are located in the same plane, and when the push plate 103 is reset, the cutting table 105 tilts to one side to facilitate unloading.

[0034] Example 2

[0035] Reference Figures 1 to 6 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0036] Specifically, a connecting rod 2025 is fixed on the push plate 103, and the connecting rod 2025 is L-shaped. A vertical rod 2026 is fixed at one end of the connecting rod 2025, and a moving block 2027 is fixed on the vertical rod 2026. Through the arrangement of the connecting rod 2025 and the vertical rod 2026, the push plate 103 can drive the moving block 2027 to move synchronously when it moves. The moving block 2027 is sleeved on the outside of the rotating column 2024. When the push plate 103 moves, the moving block 2027 will slide axially along the rotating column 2024.

[0037] Specifically, a rectangular groove 101-2 is provided on the workbench 101, and the moving block 2027 slides in the rectangular groove 101-2. The rectangular groove 101-2 is connected to the chamber 101-1. The size of the rectangular groove 101-2 corresponds to the moving block 2027. The rectangular groove 101-2 can limit the moving block 2027 to slide only in the rectangular groove 101-2 and cannot rotate.

[0038] The other end of the rotating column 2024 is connected to the inner wall of the rectangular groove 101-2 by a bearing.

[0039] Specifically, the rotating column 2024 is provided with a spiral groove 2024-1 and a linear groove 2024-2, and a slider 2028 is fixed on the moving block 2027. The slider 2028 can slide in the spiral groove 2024-1 and the linear groove 2024-2. Through the cooperation of the slider 2028 and the spiral groove 2024-1, in the initial state, the push plate 103 is located at the position farthest from the cutting table 105. At this time, the slider 2028 is located in the spiral groove 2024-1. When the push plate 103 moves, the moving block 2027 moves synchronously. At this time, the slider 2028 slides along the spiral groove 2024-1, thereby causing the rotating column 2024 to rotate. When the rotating column 2024 rotates, it drives the worm 2023 to rotate. The worm gear 2022 moves, and the worm gear 2022 drives the fixed column 2021 to rotate under the cooperation of the worm 2023 and the worm wheel 2022. At this time, the upper surface of the cutting table 105 is coplanar with the workbench 101. As the moving block 2027 moves further, before the battery is pushed to the cutting table 105 by the push plate 103, the slider 2028 slides from the spiral groove 2024-1 to the linear groove 2024-2. Then the slider 2028 slides along the linear groove 2024-2. At this time, the rotating column 2024 will not rotate. Since the worm wheel 2022 and the worm 2023 have self-locking characteristics, the cutting table 105 will maintain its original angle and be coplanar with the workbench 101, thereby ensuring that the cutting table 105 will not deviate during cutting.

[0040] During the resetting process of the push plate 103, the slider 2028 slides in the opposite direction along the linear groove 2024-2, without changing the angle of the cutting table 105. When the slider 2028 moves from the linear groove 2024-2 to the spiral groove 2024-1 and slides in the opposite direction within the spiral groove 2024-1, it drives the rotating column 2024 to rotate in the opposite direction, causing the cutting table 105 to tilt, thereby facilitating the falling of the cut battery and allowing the electrolyte on the cutting table 105 to fall into the liquid storage barrel 201.

[0041] Even if the cut battery does not fall down smoothly, the next cut battery will push the previous battery down.

[0042] Specifically, a baffle 106 is fixed on the workbench 101, and a slide groove 106-1 corresponding to the connecting rod 2025 is opened on the baffle 106. When cutting the lead-acid battery, one end face of the battery needs to be fitted with the baffle 106, and then the cylinder 102 is started to push the battery to the cutting table 105 to complete the cutting.

[0043] Example 3

[0044] Reference Figures 4 to 7 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0045] Specifically, a rotating groove 101-3 is provided on the workbench 101, and the auxiliary part 203 includes a rotating plate 2031 rotatably connected to the rotating groove 101-3. A through groove 101-4 is provided on the workbench 101, and a movable plate 2032 is slidably arranged in the through groove 101-4. The rotating plate 2031 can rotate in the rotating groove 101-3, and the movement of the movable plate 2032 can push the rotating plate 2031 to rotate. When the upper end surface of the rotating plate 2031 rotates to a state coplanar with the upper end surface of the workbench 101, the rotating plate 2031 can fill the gap between the workbench 101 and the cutting table 105, and ensure that the battery can be smoothly moved from the workbench 101 to the cutting table 105, avoiding the gap from hindering the movement of the battery.

[0046] A sleeve 2033 is fixed on the movable plate 2032, and a cylinder 2034 is slidably set in the sleeve 2033. A spring 2035 is fixed to one side of the cylinder 2034, and the other end of the spring 2035 is fixed to the movable plate 2032. The spring 2035 applies continuous thrust to the cylinder 2034 to ensure that in the absence of other forces, the upper end of the cylinder 2034 extends out of the upper surface of the workbench 101. When the push plate 103 pushes the battery to move, the battery can first contact the cylinder 2034 and push the cylinder 2034 to move, thereby driving the movable plate 2032 to move, squeezing the rotating plate 2031, and causing the rotating plate 2031 to rotate, thereby filling the gap between the workbench 101 and the cutting table 105.

[0047] When the push plate 103 is reset, the push plate 103 can contact the cylinder 2034 and drive the movable plate 2032 to move. At this time, the movable plate 2032 will not squeeze the rotating plate 2031. Under the action of gravity, the rotating plate 2031 returns to the inclined state. At this time, the electrolyte on it will also fall along the inclined surface into the liquid barrel 201.

[0048] Specifically, the elastic force of the spring 2035 is relatively large.

[0049] Specifically, a sliding groove 101 - 5 is provided on the workbench 101 , and the cylinder 2034 and the sleeve 2033 slide in the sliding groove 101 - 5 . When the cylinder 2034 and the sleeve 2033 slide in the sliding groove 101 - 5 , the movable plate 2032 can slide along the movable plate 2032 .

[0050] Specifically, one end of the cylinder 2034 is in an arc shape. Through the arc shape, due to the large elastic force of the spring 2035, the battery can first contact the cylinder 2034. At this time, the cylinder 2034 slides in the sliding groove 101-5, and drives the movable plate 2032 to move, so that the rotating plate 2031 rotates, thereby filling the gap between the workbench 101 and the cutting table 105. When the cylinder 2034 slides to the end face of the sliding groove 101-5, the cylinder 2034 cannot continue to move, and then the battery and the push plate 103 squeeze the cylinder 2034 in turn, so that the spring 2035 is compressed, and the cylinder 2034 It moves downward into the sleeve 2033 without affecting the movement of the battery and the push plate 103. When the push plate 103 no longer squeezes the cylinder 2034, the spring 2035 resets the cylinder 2034. During the reset process of the push plate 103, it will contact the cylinder 2034 again, driving the cylinder 2034 to move away from the cutting table 105. When the cylinder 2034 is in contact with the other end face of the sliding groove 101-5, the cylinder 2034 cannot move further. The push plate 103 squeezes the cylinder 2034, causing the spring 2035 to be compressed, which will not hinder the movement of the push plate 103.

[0051] Specifically, a lead-acid battery is placed on a workbench 101, with one end face of the battery in contact with a baffle 106. The cylinder 102 is then activated, and the push plate 103 pushes the battery toward the blade 104, cutting the battery shell open. The electrolyte inside flows into a liquid storage barrel 201, and the cut battery is transferred to the next process via a conveyor belt, where the plastic and metal shells are separated manually or mechanically.

[0052] The pre-treated batteries are sent to a special crusher to be broken into small pieces. Different components are separated by physical methods. Magnetic separation separates magnetic metals, eddy current separation separates copper foil and aluminum foil, and air separation separates plastic, diaphragm and metal particles according to specific gravity.

[0053] The positive electrode material is extracted from metals through hydrometallurgy, the negative electrode graphite is purified by high-temperature calcination and then reused, and the electrolyte is distilled to recover organic solvents and lithium salts.

[0054] During use, when cutting a lead-acid battery, one end face of the battery needs to be fitted with the baffle 106 , and then the cylinder 102 is started to push the battery to the cutting table 105 , and the cutting is completed with the blade 104 .

[0055] When the push plate 103 moves, the moving block 2027 moves synchronously. At this time, the slider 2028 slides along the spiral groove 2024-1, thereby causing the rotating column 2024 to rotate. The rotating column 2024 will drive the worm 2023 to rotate when rotating, so that under the cooperation of the worm 2023 and the worm gear 2022, the worm gear 2022 drives the fixed column 2021 to rotate. At this time, the upper surface of the cutting table 105 is coplanar with the workbench 101. As the moving block 2027 moves further, before the battery is pushed to the cutting table 105 by the push plate 103, the slider 2028 will slide from the spiral groove 2024-1 to the linear groove 2024-2, and then the slider 2028 will slide along the linear groove 2024-2. At this time, the rotating column 2024 2024 will not rotate. Since the worm wheel 2022 and the worm 2023 have self-locking properties, the cutting table 105 will maintain its original angle and be coplanar with the workbench 101, thereby ensuring that the cutting table 105 will not deviate during cutting. At the same time, when the push plate 103 pushes the battery to move, the battery can first contact the cylinder 2034, thereby pushing the cylinder 2034 to move, thereby driving the movable plate 2032 to move, squeezing the rotating plate 2031, and causing the rotating plate 2031 to rotate, thereby filling the gap between the workbench 101 and the cutting table 105, ensuring that the battery can be smoothly moved onto the cutting table 105, and completing the cutting. The electrolyte will flow into the liquid storage barrel 201 through the gap between the workbench 101 and the cutting table 105.

[0056] During the reset of the push plate 103, the slider 2028 slides in the opposite direction along the linear groove 2024-2, and the angle of the cutting table 105 will not be changed. When the slider 2028 moves from the linear groove 2024-2 to the spiral groove 2024-1 and slides in the opposite direction within the spiral groove 2024-1, it will drive the rotating column 2024 to rotate in the opposite direction, thereby tilting the cutting table 105, thereby facilitating the falling of the cut batteries and causing the electrolyte on the cutting table 105 to fall into the liquid storage barrel 201. When the push plate 103 is reset, the push plate 103 can contact the cylinder 2034, thereby driving the movable plate 2032 to move. At this time, the movable plate 2032 will not squeeze the rotating plate 2031. Under the action of gravity, the rotating plate 2031 returns to the inclined state. At this time, the electrolyte on it will also fall along the inclined surface into the liquid storage barrel 201.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
