[0046] The following will specifically describe the preferred embodiments of the present invention in conjunction with the accompanying drawings. Among them, the accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principle of the present invention, and are not used to limit the scope of the present invention.

[0047] Please refer to Figures 1 to 3The utility model provides a vibrating screening device for recycling waste lithium batteries, comprising: a shell 1, a crushing component 2, at least one screening component 3 and at least one knocking component 4. The interior of the shell 1 is hollow, the crushing component 2 is connected to the inner wall of the shell 1 for crushing materials, the screening component 3 is arranged below the crushing component 2 and is detachably connected to the shell 1, the knocking component 4 is arranged relative to the screening component 3, and has a first state of moving close to the screening component 3 and a second state of moving away from the screening component 3, and the knocking component 4 can repeatedly switch between the first state and the second state and knock the screening component 3.

[0048] In the present device, a crushing assembly 2 is provided inside the shell 1 for crushing the disassembled battery pack module. A screening assembly 3 is provided below the crushing assembly 2 for screening and sorting the crushed product. The knocking assembly 4 is arranged relative to the screening assembly 3 and has a first state of moving close to the screening assembly 3 and a second state of moving away from the screening assembly 3. The knocking assembly 4 can repeatedly switch between the first state and the second state to continuously knock the screening assembly 3.

[0049] Compared with the prior art, a knocking component 4 is arranged relative to the screening component 3, and the knocking component 4 is used to repeatedly switch between the first state and the second state to make the knocking component 4 continuously knock on the screening component 3, so that the material vibrates on the screening component 3, which is beneficial to the screening of the material and avoids the accumulation of the material. This can solve the technical problem in the prior art that the material is easily accumulated on the screen because multiple screens are horizontally arranged from top to bottom below the crushing bin, resulting in poor screening effect.

[0050] Furthermore, the shell 1 in the present device is a hollow can body, which is used to crush the disassembled battery modules, etc. The crushing component 2 is a crushing roller that is common and easy to purchase on the market. This is a conventional setting known to those skilled in the art and will not be described in detail.

[0051] like Figure 1 As shown, the screening assembly 3 includes at least two mounting blocks 31, a screening mesh 32 and at least two clamping parts. The at least two mounting blocks 31 are evenly distributed along the circumferential inner wall of the shell 1 and are all connected to the shell 1. The screening mesh 32 is connected to the at least two mounting blocks 31. The clamping parts are arranged in a one-to-one correspondence with the mounting blocks 31, and the clamping parts are connected to the mounting blocks 31 and are detachably connected to the screening mesh 32.

[0052] The sieve 32 is detachably connected to the inner wall of the shell 1 through at least two clamping parts cooperating with the mounting block 31, and is arranged to fit the inner surface of the shell 1, so as to facilitate the user to install and disassemble the sieve 32, and facilitate maintenance and replacement during later use.

[0053] Further, the clamping part here is the bolts and nuts that are common and easy to purchase in the market. Installation holes are respectively opened on the installation block 31 and the sieve mesh 32. The bolt passes through the two installation holes in sequence and is threadedly connected with the nut, which will not be elaborated here too much.

[0054] Further, in this device, the sieve mesh 32 can also be arranged obliquely downward, which is beneficial to the sieving of materials.

[0055] Specifically, the number of the sieving components 3 in this device is four. The four sieve meshes 32 are arranged at intervals in sequence from top to bottom and are all connected to the inner wall of the housing 1. And the number of the sieve meshes of the sieve mesh 32 gradually increases along the setting direction. The knocking components 4 are arranged in one-to-one correspondence with the sieve meshes 32 and are connected to the inner wall of the housing 1.

[0056] The four sieve meshes 32 form a multi-stage sieving structure, which is beneficial to the sieving and sorting of materials. And by knocking the four sieve meshes 32 respectively with the four knocking components 4, it is beneficial to the screening of materials.

[0057] Further, the number of meshes of the sieve meshes on the four-layer sieve mesh 32 gradually increases from less to more in sequence.

[0058] As Figures 2 to 4 shown, the knocking component 4 includes a knocking block 41, a first driving part 42, a fixing rod 43, a rotating rod 44, a shifting rod 45, an elastic stop block 46 and an elastic sheath 47.

[0059] Among them, the knocking block 41 is arranged opposite to the sieve mesh 32 and is hinged to the housing 1. The first driving part 42 has a fixed end and a movable end. The fixed end of the first driving part 42 is connected to the housing 1, and the movable end is connected to the knocking block 41, and is used to drive the knocking block 41 to rotate around its hinge with the housing 1 and repeatedly knock the sieve mesh 32.

[0060] The knocking block 41 is arranged opposite to the sieve mesh 32. Driven by the movable end of the first driving part 42, the knocking block 41 can rotate around the hinge point of its hinge as the axis to realize the knocking of the sieve mesh 32.

[0061] Specifically, the knocking block 41 is in a ball head shape.

[0062] Among them, as an implementation manner, as Figure 2 、 Figure 3 shown, one end of the fixing rod 43 is connected to the inner wall of the housing 1, and the other end extends along the direction close to the central axis of the housing 1. The rotating rod 44 is rotatably connected to the other end of the fixing rod 43. One end of the rotating rod 44 is connected to the knocking block 41. The shifting rod 45 is arranged opposite to the movable end of the first driving part 42 and is connected to the other end of the rotating rod 44, and the shifting rod 45 can drive the knocking block 41 to rotate close to the sieve mesh 32.

[0063] The fixed rod 43, the rotating rod 44 and the shifting rod 45 are used to connect the rotation of the knocking block 41, so that the first driving part 42 drives the shifting rod 45 arranged at the other end of the rotating rod 44 to rotate, and can drive the knocking block 41 arranged at one end of the rotating rod 44 to rotate in the opposite direction.

[0064] Among them, as a preferred embodiment, as Figure 2 , Figure 3 shown, the elastic stop block 46 is arranged on the rotation path of the knocking block 41 and is connected to the housing 1.

[0065] The function of the elastic stop block 46 is to play a limiting role when the knocking block 41 drives the rotating rod 44 to rotate away from the sieve 32 under the action of its own gravity, and is used to ensure that the first driving part 42 can always drive the shifting rod 45 to rotate.

[0066] Among them, as another preferred embodiment, as Figure 2 , Figure 3 shown, the distance between the rotation centers of the knocking block 41 and the rotating rod 44 is greater than the distance between the rotation centers of the shifting rod 45 and the rotating rod 44.

[0067] The shifting rod 45 and the knocking block 41 are respectively arranged at both ends of the rotating rod 44, and the distances from the rotation center of the rotating rod 44 are not equal, so that when the shifting rod 45 is dialed at a small angle, the knocking block 41 can be driven to swing at a large angle, which is used to improve the stability of the device.

[0068] Among them, as another embodiment, the elastic sheath 47 is detachably sleeved on the surface of the knocking block 41.

[0069] The elastic sheath 47 covers the surface of the knocking block 41 and is used to reduce the damage of the knocking of the knocking block 41 to the sieve 32, etc.

[0070] Furthermore, both the elastic sleeve and the elastic stop block 46 here are common and easily purchasable settings in the market, which are conventional settings well known to those skilled in the art and will not be elaborated too much here.

[0071] As Figure 2 , Figure 3 shown, the first driving part 42 includes a cam 421 and a driving motor 422. The cam 421 is rotatably connected to the housing 1 and can drive the shifting rod 45 to rotate around its rotation axis. The fixed end of the driving motor 422 is connected to the inner wall of the housing 1, and the output shaft is connected to the cam 421.

[0072] Driven by the driving motor 422, the cam 421 can rotate around its axis and drive the shifting rod 45 to move.

[0073] As Figure 1As shown, the shell 1 is also provided with a feed port and a discharge port connected to the interior thereof, and the waste lithium battery recycling vibration screening device also includes a feed bin 5, a discharge bin 6, a calcium hydroxide adsorption column 7, an aluminum hydroxide adsorption column 8 and a distillation chamber 9. The feed bin 5 and the discharge bin 6 are sequentially connected and arranged above the shell 1, and are both connected to the feed port. The calcium hydroxide adsorption column 7, the aluminum hydroxide adsorption column 8 and the distillation chamber 9 are sequentially connected and arranged on one side of the shell 1, and are all connected to the discharge port, and the discharge end of the distillation chamber 9 is connected to the interior of the discharge bin 6.

[0074] The disassembled battery pack becomes a single battery module and is put into the discharge bin 5. After the liquid in the discharge bin 6 is discharged, the crushing product is formed under the crushing of the crushing component 2. After being sieved through four layers of screening mesh 32, it is sorted. At the same time, the discharged electrolyte and mixed liquid enter the calcium hydroxide adsorption column 7, aluminum hydroxide adsorption column 8 and distillation chamber 9 in turn from the discharge port for treatment, and the treated circulating liquid enters the discharge bin 6 from the distillation chamber 9.

[0075] In the specific working process of the utility model, a crushing assembly 2 is arranged inside the shell 1 for crushing the disassembled battery pack module, a screening assembly 3 is arranged below the crushing assembly 2 for screening and sorting the crushed product, a knocking assembly 4 is arranged relative to the screening assembly 3, and has a first state of movement close to the screening assembly 3 and a second state of movement away from the screening assembly 3, and the knocking assembly 4 can repeatedly switch between the first state and the second state to continuously knock on the screening assembly 3. Compared with the prior art, by setting the knocking assembly 4 relative to the screening assembly 3, and using the knocking assembly 4 to repeatedly switch between the first state and the second state to make the knocking assembly 4 continuously knock on the screening assembly 3, the material is vibrated on the screening assembly 3, which is beneficial to the screening of the material and avoids the accumulation of the material.

[0076] When in use, a single battery module is put into the lower material bin 5, and after the liquid is discharged in the discharge bin 6, a crushed product is formed under the crushing of the crushing assembly 2, and is sorted after being screened by four layers of screening mesh 32. At the same time, the driving motor 422 drives the cam 421 to rotate, and the rotating cam 421 contacts the lever 45, and the lever 45 is moved, so that the knocking block 41 set at one end of the rotating rod 44 rotates close to the screening mesh 32 and knocks the screening mesh 32. When the cam 421 is separated from the lever block, the knocking block 41 is acted on by its own gravity and the raw material screening mesh 32 rotates. After the rotation, the rotating rod 44 abuts against the elastic stop block 46. As the cam 421 continues to rotate, the lever 45 is continuously moved, thereby driving the knocking block 41 to continuously knock the screening mesh 32.

[0077] Through the above structure, the device can solve the technical problem in the prior art that since multiple sieves are horizontally arranged one by one from top to bottom below the crushing bin, materials are likely to accumulate on the sieves, resulting in poor screening effect.

[0078] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
