Description

Technical Field

[0001] The present invention relates to the technical field of energy storage battery recycling, and in particular to a device and method for recycling lead-tin alloy from energy storage batteries. Background Art

[0002] The recycling of lead-tin alloy in energy storage batteries is an important measure involving environmental protection and resource recycling. In waste batteries, lead is one of the most important recyclable metals, and although the content of tin is relatively small, it is also a valuable recycling component. Effective recycling of lead-tin alloy in energy storage batteries not only helps to reduce pollution to the environment, but also saves natural resources and reduces production costs, which is of great significance to promoting sustainable development.

[0003] The lead-tin alloy recycling process in energy storage batteries includes the following steps: classification and disassembly, crushing and sorting, smelting and refining, and alloy adjustment.

[0004] Before smelting and refining, lead paste is separated by crushing and sorting steps. A part of coal particles needs to be mixed into the lead paste for combustion before it is put into the smelting furnace. The existing mixing method of lead paste and coal particles is relatively backward. Generally, the coal particles are shoveled onto the surface of the lead paste pile manually, and then the lead paste with coal particles is shoveled into the mixing device by a forklift for mixing and transportation. During the working process, manual coal adding is adopted. On the one hand, the work efficiency needs to be improved. On the other hand, manual addition cannot guarantee the uniformity of coal particle distribution, which affects the subsequent mixing effect. In the subsequent mixing process, since the lead paste has a certain humidity and adhesion after flotation, it is mostly accumulated in the form of blocks. Both reasons are not conducive to the diffusion of coal particles. The mixing uniformity of coal particles and lead paste is low, and the heating uniformity of the subsequent lead paste melting link cannot be guaranteed, which affects the final product quality of lead-tin alloy.

[0023] Beneficial effects:

[0024] 1. The uniform spreading mechanism adopted in the present invention adopts double-layer mixing, and the mechanism moves linearly and evenly releases coal particles in a multi-tube manner.

[0025] 2. The mixing mechanism adopted in the present invention can perform preheating stirring on the coal particles and lead paste mixed in the upper layer. During the stirring process, the lead paste is continuously broken up. The preheating heat energy comes from the recovered hot air in the subsequent lead paste melting step. The hot air is evenly filled into the lead paste to dry the wet lead paste, which can prevent the coal particles and the lead paste from sticking together and making them difficult to mix.

[0039] See also Figure 5 The mixing mechanism 5 includes a mounting shaft 51 which rotates and passes through the front and rear walls of the lower chamber 12. The mounting shaft 51 is a hollow shaft. The front end of the mounting shaft 51 is fixedly connected to the output end of the motor 3 through a synchronous belt and a pulley structure. The motor 3 is fixedly connected to the front reinforcing plate. The bottom of the lower chamber 12 is arc-shaped. A reverse auger frame 54 is arranged on the periphery of the mounting shaft 51.

[0041] By using the uniform spreading mechanism 2 and the mixing mechanism 5 in combination, the molten lead paste and coal particles can be automatically and uniformly mixed.

[0042] See also Figure 1 , Figure 2 and Figure 3The moving assembly 21 includes a vertical plate 211 integrally fixedly connected to the left side of the top of the front and rear walls of the box body 1, a screw rod 213 is rotatably connected between the vertical plates 211 on the front and rear sides and fixedly connected to a guide rod 212, a moving seat 214 is threadedly connected to the screw rod 213, and the moving seat 214 is also slidably connected to the guide rod 212, and the right side of the moving seat 214 is fixedly connected to the coal storage hopper 22, and the front end of the screw rod 213 extends to the outside of the front vertical plate 211 and is connected to the motor through multiple sets of synchronous belts and pulley structures.

[0044] See also Figure 2 and Figure 4 The dredging assembly 25 includes a dredging rod 255 that slides through the movable groove of each discharge pipe 24. A section of the dredging rod 255 located inside each discharge pipe 24 is symmetrically fixedly connected with a rod fork 254. The right end of the dredging rod 255 is fixedly connected to a limiting seat 257. The limiting seat 257 is a square. The limiting seat 257 slides and is limitedly connected in a limiting plate 256.

[0047] During specific operation, when the dredging rod 255 moves up and down, the sliding seat 252 and the limit seat 257 will jointly drive the installation frame 232 to move up and down, and the installation frame 232 will control the double-sided rack 231 to move back and forth up and down. The movement of the double-sided rack 231 will drive the rotating gear 233 to rotate, and the rotating gear 233 will control the swing arm 234 to swing back and forth. The swinging link will reciprocate and pull up or lower the claw 237, and the connecting arm 236 will adapt to the movement of the claw 237 to adjust the angle of the claw 237, so that the claw 237 has a composite movement of moving forward and backward, moving back and forth left and right, and moving up and down.

[0056] The present invention also provides a method for recycling lead-tin alloy from an energy storage battery, comprising the following steps:

[0057] S1: Put the lead paste into the upper chamber 11 through the shoveling device, then put the coal particles into the coal storage hopper 22, then run the motor 24, and open the valve of the discharge pipe 24.

[0058] S2: The motor 24 drives the multiple sets of synchronous belts and the pulley structure to rotate the screw rod 213, and the screw rod 213 rotates to control the moving seat 214 to move along the guide rod 212, and the moving seat 214 drives the coal storage bucket 22 to move backward. When the coal storage bucket 22 moves, the dredging rod 255 jointly restricted by the movable groove of the feeding pipe 24 and the limit plate 256 drives the sliding seat 252 to move along the guide groove 253. The ups and downs of the guide groove 253 control the sliding seat 252 to drive the dredging rod 255 to move up and down. The dredging rod 255 and the rod fork 254 jointly move the coal particles in the feeding pipe 24 up and down. When the dredging rod 255 moves up and down, it will pass through the sliding seat 252. Together with the limit seat 257, the installation frame 232 is driven to move up and down, and the installation frame 232 controls the double-sided rack 231 to move back and forth up and down. The movement of the double-sided rack 231 will drive the rotating gear 233 to rotate, and the rotating gear 233 controls the swing arm 234 to swing back and forth. The swinging link will reciprocate and pull up or lower the claw 237, and the connecting arm 236 adapts to the movement of the claw 237 to adjust the angle of the claw 237, so that the claw 237 has a composite movement of moving forward and backward, reciprocating left and right, and reciprocating up and down, thereby evenly diffusing the coal particles on the surface of the lead paste. When the coal storage hopper 22 moves to the rear, it stops moving and closes the valve.

[0059] S3: Open the top unloading plate 111 through the electric push rod 112 to allow the material to enter the lower chamber 12, and run the motor 3. The motor 3 rotates to control the installation shaft 51, and the installation shaft 51 drives the forward auger frame 52 and the reverse auger frame 54 to rotate. The forward auger frame 52 controls part of the material to run forward, and the reverse auger frame 54 controls part of the material to run reversely. At the same time, hot air is input into the sealing cap 1 533 through the air inlet pipe 531. The internal space of the sealing cap 1 533 is connected with the interior of the installation shaft 51. The hot air enters the installation shaft 51 and then enters the lead paste breaking rod 535 through the interior of the transfer rod 537. The hot air is sprayed from the air nozzle 534 to dry and preheat the lead paste. When the installation shaft 51 rotates, it will drive the bevel gear 1 538 to rotate around the bevel gear 2 539, thereby driving the transfer rod 537 to rotate, and the lead paste is broken up by the lead paste breaking rod 535 rotating around the central axis of the transfer rod 537.

[0060] S4: After S continues for a period of time, the mixing is completed, and the electric push rod 122 controls the bottom unloading plate 121 to discharge the materials out of the box body 1, and the mixed materials are put into the lead paste melting furnace through the conveyor belt.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
