[0028] Reference Figure 1 、2 As shown, the device for leaching and dissolving black powder from waste lithium batteries provided in an embodiment of the present invention includes an outer cylinder 100, a first stirring assembly 200 and a second stirring assembly 300; the first stirring assembly 200 includes a rotating shaft 210, a motor 220, a bracket 230 and a stirring blade 240, the rotating shaft 210 and the bracket 230 are both arranged in the outer cylinder 100, the motor 220 is used to drive the rotating shaft 210 to rotate, the bracket 230 is fixedly connected to the rotating shaft 210, a moving space 231 is formed inside the bracket 230, the moving space 231 is connected to the outside of the bracket 230, and the stirring blade 240 is installed on the outside of the bracket 230; the second stirring assembly 300 includes a stirring plate 310, the stirring plate 310 is movably arranged in the moving space 231, and when the rotating shaft 210 rotates, the stirring plate 310 can be driven to move back and forth up and down.

[0029] By arranging a stirring blade 240 on the outside of the bracket 230 and a stirring plate 310 that can move up and down inside the bracket 230, when the bracket 230 rotates and the stirring plate 310 moves up and down, the battery black powder on the periphery of the bracket 230 is stirred in the circumferential direction under the stirring of the stirring blade 240, and at the same time, the battery black powder located in the bracket 230 is stirred in the up and down directions under the action of the stirring plate 310, so that the battery black powder in the outer cylinder 100 is subjected to compound stirring, obtains sufficient fluidity, ensures the stirring effect, and improves the leaching rate of waste lithium battery black powder.

[0030] like Figure 1 、 2 As shown, during operation, the motor 220 drives the rotating shaft 210 to rotate, and the rotating shaft 210 drives the bracket 230 to rotate, and then the bracket 230 drives the stirring blade 240 to stir the black powder outside the bracket 230 in a circular direction. At the same time, the stirring plate 310 moving up and down can stir the black powder in the moving space 231 in the up and down directions.

[0031] like Figure 1 As shown, specifically, the motor 220 is installed on the top of the outer cylinder 100, and the rotating rod of the motor 220 is connected to the rotating shaft 210. The motor 220 drives the rotating shaft 210 to rotate, and the bracket 230 rotates synchronously.

[0032] Furthermore, the up and down movement of the stirring plate 310 can be driven by the rotation of the rotating shaft 210, a cylinder drive or other mechanisms.

[0033] Further, if Figure 2 、 3As shown, it also includes a linkage structure 400, and the second stirring component 300 also includes a rotating drum 320. The stirring plate 310 is installed on the rotating drum 320, and at least a portion of the rotating shaft 210 extends into the moving space 231. The rotating drum 320 is installed on the rotating shaft 210 so as to be movable up and down. The rotating shaft 210 is connected to the rotating drum 320 through the linkage structure 400. When the rotating shaft 210 rotates, the rotating shaft 210 drives the rotating drum 320 to move back and forth up and down through the linkage structure 400.

[0034] The stirring plate 310 is driven to move up and down by the rotating shaft 210, so that no additional driving structure is required, and the dissolving device has a simple structure and a small size.

[0035] During operation, the motor 220 drives the rotating shaft 210 to rotate, and the rotating shaft 210 drives the stirring blades 240 on the bracket 230 to rotate in a circular direction. At the same time, the rotating shaft 210 drives the rotating drum 320 to move up and down through the linkage structure 400.

[0036] Further, if Figure 3 、 4 As shown, the linkage structure 400 includes a wave groove ring 410 and a sliding member 420. The rotating drum 320 is mounted on the outside of the rotating shaft 210 so as to be movable up and down. The wave groove ring 410 is arranged around the outer circumferential wall of the rotating shaft 210. The wave groove ring 410 is arranged in a wave-like manner in the up and down directions, as shown in FIG. Figure 5 As shown, the rotating drum 320 is connected to the sliding member 420, and the sliding member 420 is slidably disposed in the wave groove ring 410. The linkage structure 400 adopts such a structure to simplify the structure between the rotating drum 320 and the rotating shaft 210;

[0037] During operation, the rotating shaft 210 rotates to cause the sliding member 420 of the rotating drum 320 to slide along the wave groove ring 410 of the rotating shaft 210, so that the rotating drum 320 can move up and down reciprocatingly. Figure 4 As shown, specifically, when the rotating shaft 210 is not rotating, due to the deadweight of the rotating drum 320, the sliding member 420 on the rotating drum 320 is placed at the bottom of the wave shape (point a). When the rotating shaft 210 rotates clockwise by a certain angle, the sliding member 420 on the rotating drum 320 moves to the top of the wave shape (point b) under the action of the upward inclined hypotenuse of the wave shape, and the sliding member 420 drives the rotating drum 320 to move upward for a distance. When the rotating shaft 210 rotates clockwise by a certain angle again, the sliding member 420 on the rotating drum 320 moves to the bottom of the wave shape (point c) under the action of the downward inclined hypotenuse of the wave shape, and the sliding member 420 drives the rotating drum 320 to move downward for a distance. If the rotating shaft 210 continues to rotate clockwise, the rotating drum 320 repeats the following steps: moving upward, moving downward, and moving upward under the action of the wave groove ring 410 of the rotating shaft 210.

[0038] Further, if Figure 5As shown, the linkage structure 400 also includes a plurality of connecting plates 430, which are arranged on the top of the rotating drum 320 and are arranged in sequence along the outer wall 301 of the rotating drum 321. A sliding member 420 is provided on each connecting plate 430 to facilitate the installation of the sliding member 420 on the rotating drum 320.

[0039] Specifically, the sliding member 420 is a pin; the plurality of connecting plates 430 are one or more. When the connecting plate 430 is one, there is a small gap between the rotating drum 321 and the rotating shaft 210. The connecting plate 430 is provided at the top of the rotating drum 321. Figure 3 As shown, when there are more than two connecting plates 430 , the connecting plates 430 are arranged at intervals along the circumferential direction of the rotating drum 320 , and each connecting plate 430 is provided with a sliding member 420 .

[0040] Further, if Figure 2 As shown, the stirring blade 240 is spiral-shaped, so that the stirring effect in the circumferential direction is more sufficient.

[0041] Further, if Figure 1 As shown, a guide tube 110 is provided at the bottom of the outer cylinder 100 , and the lower end of the rotating cylinder 320 extends into the guide tube 110 . The rotating cylinder 320 is slidably connected to the guide tube 110 to make the movement of the rotating cylinder 320 more stable.

[0042] Further, if Figure 3 As shown, the stirring plate 310 is horizontally arranged, and the stirring plate 310 has a through hole 311 extending in the up and down directions along the rotating shaft 210, so as to stir the black powder in the moving space 231 in the most powerful up and down directions, thereby increasing the stirring force. At the same time, during the stirring process, the through hole 311 can allow part of the liquid to pass through, thereby reducing the resistance of the stirring plate 310 during the up and down movement. At the same time, when the liquid passes through the through hole 311 during the up and down movement, the liquid will form a small vortex, which is also a stirring, thereby further increasing the degree of stirring.

[0043] Further, if Figure 3 As shown, a plurality of stirring plates 310 are provided, and the plurality of stirring plates 310 are equally spaced along the vertical direction of the rotating shaft 210 to make the stirring more uniform, thereby improving the uniformity of the stirring of the liquid in the outer cylinder 100 and improving the leaching rate.

[0044] Specifically, if Figure 3 As shown, the multiple stirring plates 310 are divided into two rows, wherein the stirring plates 310 in one row are located on one side of the side wall of the rotating drum 320 , and the stirring plates 310 in the other row are located on the other side of the side wall of the rotating drum 320 , which is beneficial to improve the uniformity of the liquid stirring in the outer drum 100 .

[0045] Specifically, the rotating cylinder 320 includes a first cylinder 321 and a second cylinder 322. The first cylinder 321 is installed on the top of the second cylinder 322. The first cylinder 321 is sleeved outside the rotating shaft 210. The bottom of the second cylinder 322 is inserted into the guide tube 110. The diameter of the second cylinder 322 is smaller than the diameter of the first cylinder 321. The stirring plate 310 is installed on the second cylinder 322 so that the length of the stirring plate 310 can be designed to be longer, which is beneficial to improve the uniformity of liquid stirring in the outer cylinder 100.

[0046] Further, if Figure 1 、 6 As shown, the outer cylinder 100 has a feeding port 120; when on the horizontal projection plane, the feeding port 120 is located on the outside of the stirring blade 240; the battery black powder has a large specific gravity, and since the projection of the feeding port 120 does not fall on the stirring blade 240, it is avoided that when the battery black powder is fed from the feeding port 120, the battery black powder hits the stirring blade 240 and damages the stirring blade 240.

[0047] Among them, Figure 3 As shown, the horizontal projection plane is parallel or approximately parallel to the horizontal extension direction of the stirring plate 310 and is parallel to the axis of the rotating shaft 210 .

[0048] Specifically, if Figure 1 As shown, the outer cylinder 100 is provided with an end cover 500 for covering the feeding port 120 to prevent the dust in the outer cylinder 100 from leaking out.

[0049] Further, if Figure 2 As shown, the first stirring component 200 also includes a rotating plate 250, and the bracket 230 includes a plurality of mounting bars 232. The rotating plate 250 is fixedly connected to the rotating shaft 210. The plurality of mounting bars 232 are arranged in sequence along the outer wall 251 of the rotating plate 250. The plurality of mounting bars 232 enclose a moving space 231. At least two mounting bars 232 are connected to the rotating shaft 210 through the rotating plate 250 to simplify the structure of the first stirring component 200. During stirring, the solution and black powder outside the bracket 230 can enter the moving space 231 from the space between two adjacent mounting bars 232, or the solution and black powder in the moving space 231 can be discharged from the space between two adjacent mounting bars 232 to the outside of the bracket 230.

[0050] When the utility model works:

[0051] The motor 220 drives the rotating shaft 210 to rotate, and the rotating shaft 210 drives the bracket 230 to rotate, and then the bracket 230 drives the stirring blade 240 to stir the black powder and solution outside the bracket 230 in a circumferential direction. At the same time, through the rotation of the rotating shaft 210, the sliding member 420 of the rotating drum 320 slides along the wave groove ring 410 of the rotating shaft 210, so that the rotating drum 320 can move back and forth up and down, stirring the black powder and solution inside the bracket 230 in an up and down direction.

[0052] Although the technical solutions of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these technical solutions without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
