Description

Technical Field

[0001] This utility model relates to the field of battery recycling technology, and in particular to a high-efficiency hydraulic separation device for recycling waste lead-acid batteries. Background Technology

[0002] Lead-acid batteries are rechargeable secondary batteries that use lead and its oxides as electrode materials and sulfuric acid solution as electrolyte. The positive electrode active material is lead dioxide (PbO2), the negative electrode active material is spongy lead (Pb), and the electrolyte is dilute sulfuric acid (H2SO4). It is one of the most widely used chemical power sources, characterized by low cost, mature technology, and high reliability, and is widely used in automotive starting systems, energy storage systems, and backup power supplies.

[0003] The main function of lead-acid batteries is to convert chemical energy into electrical energy and release it to power devices when needed. They are commonly used to provide instantaneous high current (such as for starting a car), stable power supply (such as UPS uninterruptible power supplies), and energy storage (such as solar energy storage systems). Due to their simple structure, convenient maintenance, and low cost, they play an irreplaceable role in industries such as transportation, communication, and power.

[0033] Example 1

[0034] A high-efficiency hydraulic sorting device for recycling waste lead-acid batteries includes a screening frame 1, which serves as the basic framework of the entire device, providing support and installation positions for other components. Two collection chambers 2 are fixedly connected to the bottom of the screening frame 1. The main function of the collection chambers 2 is to collect the sorted materials. Magnetic plates 3 are slidably connected to the inner walls of both sides of the collection chambers 2. The magnetic plates 3 are responsible for adsorbing metal fragments generated after screening. Utilizing the magnetic principle, the metal fragments are adsorbed onto their own surface, preventing them from mixing with other materials, thereby reducing wear on subsequent mechanical parts and heavy metal pollution load in the water treatment process. Sliding plates 4 are fixedly connected to the front ends of the two magnetic plates 3. The outer walls of the sliding plates 4 are slidably connected to the inner walls of the collection chambers 2. When cleaning the magnetic plates 3 is required, the sliding plates 4 can slide on the inner walls of the collection chambers 2, moving the magnetic plates 3 outwards. This is a key structure for removing and cleaning the magnetic plates 3. A fixing rod 5 is fixedly connected to the front end of the sliding plate 4, and a rotating plate 6 is rotatably connected to the outer wall of the fixing rod 5. 5 provides a rotation support point for the rotating plate 6. A square block 7 is fixedly connected to the front side of the collection chamber 2. A square groove 8 is opened at the bottom of the square block 7. A locking block 9 is slidably connected to the inner wall of the square groove 8. The structure of the square groove 8 limits the sliding direction of the locking block 9 and ensures the stability of the locking block 9 when moving up and down. A locking groove is opened at the top of the rotating plate 6. The inner wall of the locking groove engages with the outer wall of the locking block 9. The function of the locking block 9 in the device is to control the limiting state of the rotating plate 6 by moving up and down. It is a key control point to ensure that the magnetic suction plate 3 can be successfully removed for cleaning. A sliding rod 10 is fixedly connected to the top of the locking block 9. The outer wall of the sliding rod 10 is slidably connected to the inner wall of the square block 7. A sliding post 11 is fixedly connected to the top of the sliding rod 10. The outer wall of the sliding post 11 is slidably connected to the inner wall of the square block 7. The square block 7 provides space for the installation and sliding of components such as the locking block 9 and the sliding rod 10. When the sliding post 11 moves upward, the sliding rod 10 moves upward accordingly, causing the locking block 9 to move upward, thereby releasing the engagement with the rotating plate 6. A return spring 12 is sleeved on the outside of the sliding post 11. The bottom side of the return spring 12 is fixedly connected to the top side of the sliding rod 10, and the top side of the return spring 12 is fixedly connected to the square block. When the sliding column 11 is pulled upward, the return spring 12 is stretched on the top inner wall of 7. After the operation is completed, the return spring 12 uses its own elastic restoring force to reset the relevant components, ensuring that the equipment can repeat normal operation. The top of the sliding column 11 is fixedly connected to the pull plate 13. The bottom side of the pull plate 13 contacts the top side of the square block 7. The pull plate 13 is the part where the operator applies operating force. By pulling the pull plate 13 upward, the sliding column 11 can be easily moved upward. The top of the screening frame 1 is fixedly connected to the top plate 18. The top plate 18 is equipped with a buffer component for feeding waste batteries.

[0035] Two collection chambers 2 are fixedly connected to the bottom of a collection shell 14. The collection shell 14 contains a conveying device and is mainly used to collect materials falling from the collection chamber 2. The conveying device then transports the materials to other processing stages. It serves as a transitional structure connecting collection and subsequent processing steps, ensuring smooth material transfer. A support plate 15 is fixedly connected to the right side of the screening frame 1. The top side of the support plate 15 contacts the bottom side of the collection shell 14, providing support and ensuring the stability of the collection shell 14 during operation. Two vibration motors 16 are fixedly connected to the right side of the screening frame 1. Multiple chain conveyor belts 17 are installed inside the screening frame 1. The vibration motors 16 are fixed to the right side of the screening frame 1. They generate vibration, allowing the materials inside the screening frame 1 to be better screened on the chain conveyor belts 17. Vibration promotes the separation of different materials according to their respective characteristics. The chain conveyor belts 17 are used to transport the crushed waste lead-acid battery fragments. A water pump 23 is fixedly connected to the top of the top plate 18. When the water pump 23 is working, it draws water from the inlet 24 and delivers the water to the inside of the equipment through the outlet pipe 25, providing water flow power for the hydraulic separation of waste lead-acid batteries. It is the core power equipment for hydraulic separation. The inlet 24 is fixedly connected to the input end of the water pump 23. The inlet 24 is the entrance for external water sources to enter the water pump 23. Multiple outlet pipes 25 are fixedly connected to the output end of the water pump 23. The outlet pipes 25 deliver the water output by the water pump 23 to the inside of the equipment, providing the necessary water flow for hydraulic separation.

[0036] Example 2

[0037] The buffer assembly includes an inclined plate 20. An inlet 19 is located on the right side of the top plate 18, serving as the channel for waste lead-acid batteries to enter the equipment and limiting the entry path of battery fragments. The right side of the inclined plate 20 is fixedly connected to the inner right wall of the inlet 19. Multiple buffer springs 21 are fixedly connected to the top of the inclined plate 20, and a buffer plate 22 is fixedly connected to the top of each buffer spring 21. The outer wall of the buffer plate 22 is slidably connected to the inner wall of the inlet 19, and the inner wall of the buffer plate 22 is slidably connected to the outer wall of the inclined plate 20. The inclined plate 20 provides a mounting base for the buffer springs 21. Its inclined structure guides the battery fragments towards the buffer plate 22. When waste battery fragments enter from the inlet 19, the buffer plate 22 directly bears the impact force of the battery fragments. The buffer springs 21 absorb the impact force generated by the falling battery fragments through their elastic deformation, reducing damage to the sorting chamber from sharp metal fragments. This is a crucial component for protecting the equipment.

[0038] Work steps

[0039] Working principle: The magnetic plate 3 is used to adsorb the metal fragments generated after screening. When the adsorption reaches a certain level and needs to be removed for cleaning, the pull plate 13 is pulled upward to move the sliding column 11 upward. The upward movement of the sliding column 11 drives the sliding rod 10 upward, which in turn drives the locking block 9 upward to release it from the locking of the rotating plate 6. This allows the rotating plate 6 to rotate clockwise and disengage from the limit of the square block 7. Then, the sliding plate 4 is pulled outward and moves the magnetic plate 3 outward, thus removing and cleaning the magnetic plate 3. The magnetic plate 3 avoids wear on mechanical parts caused by metal fragments and reduces the heavy metal pollution load in subsequent water treatment processes.

[0040] When waste lead-acid batteries need to be sorted and processed, the waste batteries are crushed and put into the screening frame 1 through the feed port 19 on the top plate 18. At this time, the crushed batteries will fall onto the buffer plate 22, and the impact force will compress the buffer spring 21 set at the bottom of the buffer plate 22. The buffer spring 21 absorbs the impact energy, thereby reducing the impact energy of the crushed battery fragments containing lead paste, metal and plastic falling, and avoiding damage caused by sharp metal fragments directly hitting the sorting chamber.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
