Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery recycling technology, specifically to a waste lead-acid battery separation device. Background Technology

[0002] Waste lead-acid batteries are corrosive and hazardous waste. Direct landfilling or other treatments would negatively impact the environment, and since the lead grids and plastic parts of waste batteries can be sorted and recycled, this would also result in resource waste. Therefore, waste lead-acid batteries are usually collected, crushed, and then recycled. This not only prevents environmental pollution but also allows for the reuse of recyclable parts (lead grids and plastic parts), conserving resources. Currently, waste lead-acid batteries are mainly processed using wet dismantling methods. This involves crushing the waste lead-acid batteries in a crusher and then separating them using the density differences of their components and hydrodynamic sorting equipment.

[0003] Due to the wide variety of lead-acid batteries, existing single-cylinder hydrodynamic sorting equipment cannot provide precise control, resulting in the inability to accurately separate the lead grids and plastic after the batteries are broken, leading to material contamination and waste. Therefore, there is an urgent need for a waste lead-acid battery separation device to solve the above problems. Utility Model Content

[0004] To address the technical problem that existing single-cylinder hydrodynamic sorting equipment cannot be precisely controlled, resulting in the inability to accurately separate the lead grids and plastics after lead-acid batteries are broken, thus leading to material contamination and waste, this utility model provides a waste lead-acid battery separation device. It is suitable for the effective separation of lead grids and plastics from different types of lead-acid batteries, achieving precise separation of lead grids and plastics and improving the quality of the produced lead grid and plastic products.

[0005] This utility model provides a waste lead-acid battery separation device, including a separator installed on the working ground. The separator is connected to an air inlet device and a water inlet device. The separator is sequentially provided with a feed inlet, a first discharge outlet connected to a lead grid conveying mechanism, and a second discharge outlet connected to a plastic conveying mechanism. A first adjusting plate is movably installed inside the separator, and a second adjusting plate is movably installed at the second discharge outlet. The top of the second adjusting plate is lower than the top of the first adjusting plate.

[0006] Furthermore, the first adjusting plate divides the interior of the separator into a primary separation chamber and a secondary separation chamber that are connected. The feed inlet is located directly above the primary separation chamber, the first discharge outlet is located below the lower connection point of the primary and secondary separation chambers, and the second discharge outlet is located on the same side of the secondary separation chamber.

[0007] Furthermore, the inner wall of the separator is evenly provided with multiple slots, and the first adjusting plate includes a fixed sleeve and a movable plate nested on the fixed sleeve. The two sides of the fixed sleeve are locked in the slots, and the movable plate moves up and down relative to the fixed sleeve.

[0008] Furthermore, the second adjusting plate is fixedly connected to the second discharge port by bolts, and the second adjusting plate moves up and down relative to the second discharge port.

[0009] Furthermore, the plastic conveying mechanism includes a vibrating screen, a second screw conveyor, and a plastic storage bin, which are set on the working ground and located on the side of the separator. The feeding port of the vibrating screen is connected to the second discharge port through a conveying pipe. The discharging port of the vibrating screen is connected to the lower part of the second screw conveyor. The upper part of the second screw conveyor is connected to the plastic storage bin. The bottom of the vibrating screen is also connected to a water tank set on the working ground.

[0010] Furthermore, the first discharge port is fixedly connected to the separation pipe, the middle part of the separation pipe is connected to the air inlet device and the water inlet device, and the lower part of the separation pipe is connected to the lead grid conveying mechanism. The separation pipe facilitates the connection between the separator and the air inlet device, the water inlet device, and the lead grid conveying mechanism.

[0011] Furthermore, the lead grid conveying mechanism includes a first screw conveyor and a lead grid storage bin, which are disposed on the working ground and located on the side of the separator. The lower part of the first screw conveyor is connected to the separation pipe, and the upper part of the first screw conveyor is connected to the plastic storage bin.

[0012] Furthermore, the air intake device includes an air compressor installed on the working ground, the air compressor being connected to the separation pipe via an air intake pipe, and the air intake pipe being equipped with a flow valve and a pressure regulating valve.

[0013] Furthermore, the intake pipe includes a first section, a second section, a third section, and a fourth section, and the angle formed between the fourth section of the intake pipe and the separation pipe is ≤45°; the intake pipe is provided in multiple sections, and the angle between the annular pipe walls of two adjacent intake pipes is ≤120°.

[0014] Furthermore, the water inlet device includes a water tank installed on the working ground, the water tank being connected to a separation pipe via an inlet pipe, and the inlet pipe being equipped with a flow regulating pump and a one-way check valve.

[0015] Compared with the prior art, the present invention has the following technical effects:

[0016] The material (broken grids, grids and plastic-adhered material) enters the primary separation chamber through the inlet. Water and air disperse the material and blow it all into the secondary separation chamber. Water and air cause the plastic to float at the top of the secondary separation chamber, and the plastic enters the plastic conveying mechanism through the second outlet. Since the weight of the lead grids is greater than that of the plastic, the lead grids fall to the bottom of the secondary separation chamber and enter the lead grid conveying mechanism through the lower connection point between the primary and secondary separation chambers. This utility model of waste lead-acid battery separation device is suitable for the effective separation of lead grids and plastics from different types of lead-acid batteries, achieving fine separation of lead grids and plastics and improving the quality of the produced lead grid and plastic products. Furthermore, the separation operation is simple, safe, reliable, and low-cost. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-4As shown, a waste lead-acid battery separation device includes a separator 1 installed on a working surface. The separator 1 is connected to an air inlet device and a water inlet device. The separator 1 is sequentially provided with a feed inlet, a first discharge outlet connected to a lead grid conveying mechanism 5, and a second discharge outlet connected to a plastic conveying mechanism 4. A first adjusting plate 2 is movably installed inside the separator 1, dividing the interior of the separator 1 into a primary separation chamber 11 and a secondary separation chamber 12 that are connected. The feed inlet is located directly above the primary separation chamber 11, the first discharge outlet is located below the lower connection point of the primary separation chamber 11 and the secondary separation chamber 12, and the second discharge outlet is located on the same side as the secondary separation chamber 12. A second adjusting plate 3 is movably installed at the second discharge outlet, and the top of the second adjusting plate 3 is lower than the top of the first adjusting plate 2. In this embodiment, the top of the first adjusting plate 2 is always three centimeters higher than the top of the second adjusting plate 3.

[0025] The working process of the waste lead-acid battery separation device: the air inlet device and the water inlet device supply compressed air and water to the separator 1 respectively. The water is in a rolling state inside the separator 1. Water and air exist in the primary separation chamber 11 and the secondary separation chamber 12. Among them, the water and air in the primary separation chamber 11 are larger.

[0026] The material (fragmented grid, grid and plastic-adhered material) enters the primary separation chamber 11 through the feed inlet. Water and air disperse the material and blow it all into the secondary separation chamber 12 (the material passes over the first regulating plate 2 to enter the secondary separation chamber 12). Water and air cause the plastic to float at the top of the secondary separation chamber 12, and the plastic enters the plastic conveying mechanism 4 through the second discharge port. The weight of the lead grid is greater than the weight of the plastic, so the lead grid falls to the bottom of the secondary separation chamber 12. The lead grid can enter the lead grid conveying mechanism 5 through the lower connection point between the primary separation chamber 11 and the secondary separation chamber 12.

[0027] If there is any shards of the grid and plastic adhering to each other, the adhering shards of the grid and plastic cannot enter the second discharge port. Instead, they will return to the first separation chamber 11 through the lower connection point between the first separation chamber 11 and the second separation chamber 12, and repeat the above steps to separate them.

[0028] The first adjusting plate 2 and the second adjusting plate 3 can be adjusted to meet the separation requirements of lead grids and plastics for different types of lead-acid batteries.

[0029] The waste lead-acid battery separation device of this embodiment is suitable for the effective separation of lead grids and plastics from different types of lead-acid batteries, achieving fine separation of lead grids and plastics and improving the quality of the produced lead grid and plastic products. Furthermore, the separation operation is simple, safe, reliable, and low-cost.

[0030] In one possible implementation, the inner wall of the separator 1 is evenly provided with multiple slots 9. The first adjusting plate 2 includes a fixed sleeve 21 and a movable plate 22 nested on the fixed sleeve 21. The two sides of the fixed sleeve 21 are engaged in the slots 9, and the movable plate 22 moves up and down relative to the fixed sleeve 21. Furthermore, the movable plate 22 can move up and down relative to the fixed sleeve 21. After the position of the movable plate 22 is determined, the movable plate 22 is then locked to the fixed sleeve 21 by bolts.

[0031] The movable plate 22 moves up and down relative to the fixed sleeve 21 to adjust the height of the first adjusting plate 2, thereby controlling the liquid level in the primary separation chamber 11. The fixed sleeve 21 is engaged in different slots 9 to adjust the position of the first adjusting plate 2, thereby controlling the volume ratio of the primary separation chamber 11 to the secondary separation chamber 12 to be ≥3:1. The larger the volume of the primary separation chamber 11, the more water and air enter it. The first adjusting plate 2 is adjusted to ensure that the material passes over the first adjusting plate 2 before entering the secondary separation chamber 12. The first adjusting plate 2 is adjusted for different types of lead-acid batteries to meet the separation requirements of the lead grid and plastic in different types of lead-acid batteries.

[0032] In one possible implementation, the second adjusting plate 3 is fixedly connected to the second discharge port by bolts, and the second adjusting plate 3 moves up and down relative to the second discharge port. The height of the second adjusting plate 3, moving up and down relative to the second discharge port, controls the liquid level in the secondary separation chamber 12. The adjustment of the second adjusting plate 3 ensures that plastic flows out of the second discharge port. The second adjusting plate 3 is adjusted for different types of lead-acid batteries to meet the separation requirements of lead grids and plastics in different types of lead-acid batteries.

[0033] In one possible implementation, the plastic conveying mechanism 4 includes a vibrating screen 41, a second screw conveyor 42, and a plastic storage bin 43, all mounted on the working surface and located to the side of the separator 1. The feed inlet of the vibrating screen 41 is connected to a conveying pipe and a second discharge outlet. The conveying pipe is connected to the feed inlet and the second discharge outlet via a nut flange. Generally, the vibrating screen 41 is located at an angle relative to the separator 1, and the conveying pipe is inclined. The discharge inlet of the vibrating screen 41 is connected to the lower part of the second screw conveyor 42, and the upper part of the second screw conveyor 42 is connected to the plastic storage bin 43. The bottom of the vibrating screen 41 is also connected to a water tank 7 mounted on the working surface. The structure of the vibrating screen 41 and the second screw conveyor 42 is existing technology and will not be described in detail here. Plastic and some water fall onto the vibrating screen 41 through the second discharge port and conveying pipe. The vibrating screen 41 starts to shake off the water, which returns to the water tank 7 for reuse. The plastic, vibrating on the screen 41, enters the second screw conveyor 42. The second screw conveyor 42 starts to move the plastic on it, eventually leading it into the plastic storage silo 43. The plastic awaits further processing in the plastic storage silo 43.

[0034] In one possible implementation, the first discharge port is fixedly connected to the separation pipe 13. The middle part of the separation pipe 13 is connected to the air inlet device and the water inlet device, and the lower part of the separation pipe 13 is connected to the lead grid conveying mechanism 5. The separation pipe 13 is connected to the first discharge port and the lower part of the lead grid conveying mechanism 5 via a nut flange. The separation pipe 13 facilitates the connection of the separator 1 with the air inlet device, the water inlet device, and the lead grid conveying mechanism 5.

[0035] In one possible implementation, the lead grid conveying mechanism 5 includes a first screw conveyor 51 disposed on the working ground and located beside the separator 1, and a lead grid storage bin 52. The lower part of the first screw conveyor 51 is connected to the separation pipe 13, and the upper part of the first screw conveyor 51 is connected to the plastic storage bin 43. The structure of the first screw conveyor 51 is prior art and will not be described in detail here. The lead grid falls from the separation pipe 13 into the lower part of the first screw conveyor 51. The first screw conveyor 51 starts, driving the lead grid on it to move, and finally the lead grid enters the lead grid storage bin 52. The lead grid waits in the lead grid storage bin 52 for the next operation.

[0036] Specifically, water and gas exist in the primary separation chamber 11 and the secondary separation chamber 12, as well as in the separation pipe 13 and the first screw conveyor 51, wherein the water level in the first screw conveyor 51 is lower than the height of the upper part of the first screw conveyor 51.

[0037] In one possible implementation, the air intake device includes an air compressor 6 installed on the working surface. The air compressor 6 is connected to the separator pipe 13 via an air intake pipe, and the air intake pipe is equipped with a flow valve and a pressure regulating valve. The structure of the air compressor 6 is prior art and will not be described in detail here. The air intake pipe regulates the amount of compressed air entering the separator 1 per unit time through the flow valve, and regulates the compressed air intake pressure through the pressure regulating valve, with a pressure regulation range of 2 MPa to 6 MPa.

[0038] In one possible implementation, the intake pipe includes a first section, a second section, a third section, and a fourth section, wherein the angle between the fourth section of the intake pipe and the separation pipe 13 is ≤45°. Only one intake pipe is shown in this embodiment. The angle between the fourth section of the intake pipe and the separation pipe 13 is ≤45°, allowing more compressed air to enter the primary separation chamber 11.

[0039] As one possible implementation, multiple air intake pipes are provided, with the annular wall angle between two adjacent air intake pipes ≤ 120°. Multiple air intake pipes can be provided as needed to meet the air intake requirements of the separator 1. When multiple air intake pipes are provided, the annular wall angle between two adjacent air intake pipes is ≤ 120°, allowing more compressed air to enter the primary separation chamber 11.

[0040] In one possible implementation, the water inlet device includes a water tank 7 installed on the working surface. The water tank 7 is connected to the separation pipe 13 via an inlet pipe, and the inlet pipe is equipped with a flow regulating pump 8 and a one-way check valve. The flow regulating pump 8 regulates the circulating water volume of the separator 1. The water in the water tank 7 is reused, reducing costs. Water that falls after passing through the vibrating screen 41 can return to the water tank 7 for subsequent reuse. The one-way check valve prevents water backflow.

[0041] As one possible implementation, a sealing plate is bolted to the feed inlet. When using the separator 1, the sealing plate is opened; otherwise, it is closed.

[0042] The embodiments described above are merely preferred embodiments of this utility model and are only used to explain this utility model. They are not intended to limit the scope of implementation of this utility model. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification.
