Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery recycling, in particular to a device for separating lead raw materials and shells used in lead-acid battery recycling. Background Art

[0002] Lead-acid battery recycling typically involves disassembly and crushing, but both inevitably produce large amounts of broken material, particularly in the crushing and separation method. This material is a mixture of lead pellets, plastic, lead sludge, and electrolyte. In practice, separation effectiveness has been hampered by factors such as high water consumption, incomplete separation, high power consumption, and long separation cycles. Furthermore, manual disassembly poses significant risks to both the environment and human health.

[0003] Patent document CN219540447U discloses a lead-acid battery crushing and screening device. During operation, used lead-acid batteries are placed into a feed hopper. Guided by an inclined plate, the batteries slide between the two shredder wheels, where they are squeezed and shredded. The shredded lead-acid battery fragments fall onto a shaking plate on a receiving platform. A vibration motor then drives the shaking plate to shake, separating the plastic and metal fragments, preventing them from sinking underwater with the attached metal fragments and affecting the screening effect. After a period of shaking, the main electronic control push rod is retracted, driving the receiving platform down into the water. Due to the buoyancy of the water, the plastic fragments, i.e., the lead-acid battery shell fragments, float on the surface, while the metal fragments sink, completing the screening and sorting of the metal and plastic fragments. Finally, the auxiliary electronic control push rod is controlled to push out, and the push plate pushes the plastic fragments floating on the water surface through the slot and into the collection box, completing the screening of the waste battery fragments. The process of separating the lead raw material from the broken plastic shells in this device requires a large amount of water. Later, the water and lead raw material need to be separated. When the broken plastic shells are contaminated with a large amount of lead raw material, the broken plastic shells with lead raw material tend to sink into the water, and the separation of lead raw material and broken plastic shells is not complete.

[0004] Patent publication number CN111957572B discloses a device for separating lead raw material from lead shells for lead-acid battery recycling. During operation, the motor is activated, and the cylinders within the rotating drum are sequentially activated, staggering the extension and contraction of the cylinders of two adjacent centrifugal units. Specifically, when one cylinder is extended, the adjacent cylinder is contracted. This allows the receiving plates of the two adjacent centrifugal units to be in a discharging state while the other is in a receiving state, achieving layer-by-layer material transfer. The motor drives a first gear via a rotating shaft. This first gear, in conjunction with an outer ring gear, drives the rotating drum, which in turn rotates a cylindrical cam and the centrifugal units within the drum. This device separates the lead raw material through centrifugal action. As the cylinder in the second centrifugal unit contracts, the cylinder in the third centrifugal unit extends, causing the receiving plate in the third unit to gradually become horizontal, catching material that falls from the second centrifugal unit. However, as the drum rotates, the material on the receiving plate moves toward the drum's sidewalls due to centrifugal force. Once the material on the receiving plate accumulates on the drum's wall, it rotates with the drum. Although some lead material can be ejected due to centrifugal force, the lead material trapped in the material cannot be effectively discharged because the material and the drum cannot move relative to each other.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1: Reference Figure 1 and Figure 3 As shown, the lead raw material and shell separation device for lead-acid battery recycling includes a box body 1, a preliminary separation device is provided in the box body 1, and a feed pipe 2 corresponding to the preliminary separation device is fixed at the upper end of the box body 1.

[0025] The preliminary separation device includes a storage tank 3 fixed within a housing 1. A lower pipe 20 is fixed to the lower end of the housing 1 and communicates with the storage tank 3. An inclined chute 4 is fixed to the upper end of the storage tank 3. The lower end of the feed pipe 2 extends into the chute 4. A filter screen 5 is fixed to the bottom of the chute 4. A flow limiting plate 6 is fixed within the chute 4 above the filter screen 5. A gap is provided between the lower end of the flow limiting plate 6 and the filter screen 5. Material discharged from the feed pipe 2 enters the chute 4. The flow limiting plate 6 can limit the flow of material moving within the chute 4. A vibrator 21 is fixed to the lower end of the filter screen 5. A material trough 7 is fixed to the end of the chute 4 facing the rotating drum 16.

[0026] After the batteries are crushed, the material to be separated falls through the feed pipe 2 into the chute 4 and is supported by the filter 5. As the material slides on the filter 5, some lead material can pass through the filter 5 and fall into the storage tank 3. The lead material in the storage tank 3 can be discharged through the lower pipe 20. In this embodiment, the lead material separated by the filter 5 is mainly crushed lead paste. As the material slides in the chute 4, the vibrator 21 is activated to accelerate the separation of the lead material from the crushed plastic.

[0027] As the material moves within the chute 4, the flow restrictor 6 limits the material's flow, ensuring the material's retention time within the chute 4 and ensuring the efficiency of the initial separation of the lead raw material and crushed plastic within the chute 4. The material is discharged from the chute 4 through the trough 7.

[0028] Example 2: Based on Example 1, refer to Figure 1 and Figure 2 As shown, a centrifugal separation device is fixed in the box body 1 on one side of the preliminary separation device, and the material discharged from the preliminary separation device can enter the centrifugal separation device.

[0029] The centrifugal separator includes a fixed sleeve 18 fixed to the lower end of the housing 1. An outlet pipe 19 is fixedly connected to one side of the fixed sleeve 18 below the rotating drum 16. The rotating drum 16 is rotatably mounted within the fixed sleeve 18. A guide plate 17 is fixed within the fixed sleeve 18 below the rotating drum 16. The guide plate 17 is tilted downward toward one end of the outlet pipe 19, with the inlet end of the outlet pipe 19 located above the guide plate 17. The chute 4 is tilted downward toward one end of the rotating drum 16.

[0030] The fixed sleeve 18 is provided with a driving unit for driving the rotating drum 16 to rotate. Specifically, the driving unit includes a motor fixed on the fixed sleeve 18, a gear is concentrically fixed on the output shaft of the motor, and a gear ring is concentrically fixed on the outer side of the rotating drum 16, and the gear and the gear ring are meshed.

[0031] A retaining ring 8 is fixed within the housing 1 above the rotating drum 16. Specifically, the retaining ring 8 is secured between the storage tank 3 and the left side wall of the housing 1. The lower end of the retaining ring 8 is fixedly connected to a conical ring 10 via multiple connecting rods 9. A conical ring 10 is secured to the lower end of the retaining ring 8. Conical ring 10 is positioned within the rotating drum 16. A conical filter ring 12 is secured within the rotating drum 16 below the conical ring 10. Multiple support rods 11 are secured to the lower end of the conical ring 10. Specifically, a gap is provided between the upper outer edge of the conical ring 10 and the inner wall of the rotating drum 16, and a gap is provided between the lower ends of the support rods 11 and the conical filter ring 12.

[0032] The lower end of the conical filter ring 12 is concentrically fixedly connected to a discharge pipe 13, an electromagnetic valve is installed in the upper end of the discharge pipe 13, the lower end of the discharge pipe 13 is connected to the discharge pipe 15 through a rotary joint 14, the lower end of the discharge pipe 15 is fixed on the bottom plate of the box body 1, and the lower end of the discharge pipe 15 extends to the bottom of the box body 1.

[0033] After sliding from trough 7, the material passes through retaining ring 8 and conical ring 10 and enters conical filter ring 12. At this point, the solenoid valve closes. The motor is started, driving drum 16 via the gears and ring gear. As drum 16 rotates, centrifugal force forces the material on conical filter ring 12 toward the drum wall, where it strikes multiple support rods 11. This impact dislodges any lead material adhering to the crushed plastic. Furthermore, the support rods 11 disperse any clumped material, improving the separation efficiency of the crushed plastic from the lead material.

[0034] The drum 16 rotates intermittently. After the drum 16 stops rotating, the material accumulated on one side of the drum 16 slides toward the center of the conical filter ring 12 under the guidance of the inner conical surface of the conical filter ring 12. As the material slides toward the center of the conical filter ring 12, the support rod 11 can again move the material, further improving the separation efficiency of the crushed plastic and the lead raw material. In this embodiment, the lead raw material is primarily crushed lead paste. After passing through the conical filter ring 12, the lead raw material falls into the fixed sleeve 18. The lead raw material in the fixed sleeve 18 is guided by the guide plate 17 and is easily discharged through the outlet pipe 19.

[0035] When the drum 16 and the conical filter ring 12 rotate, the discharge pipe 13 rotates accordingly. Since the discharge pipe 13 is connected to the discharge pipe 15 through the rotary joint 14, the discharge pipe 15 will not hinder the rotation of the drum 16 and the conical filter ring 12.

[0036] After the lead raw materials in the material are separated, the solenoid valve is opened, and the material in the conical filter ring 12 is discharged through the discharge pipe 13, the rotary joint 14, and the discharge pipe 15. The material discharged from the discharge pipe 15 contains particles such as crushed plastic, crushed grid, and lead metal blocks. The crushed plastic can be separated from the material discharged from the discharge pipe 15 by water separation.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
