Description

Technical Field

[0001] This utility model relates to the field of ternary lithium battery recycling technology, specifically to a high-efficiency purification and separation device for ternary regenerated leachate. Background Technology

[0002] The ternary lithium battery recycling leachate high-efficiency purification and separation device is a device specifically designed for treating the leachate generated during the recycling of waste ternary lithium batteries.

[0003] A search revealed a Chinese patent for a ternary leaching solution separation device, publication number CN 222286611 U, belonging to the field of ternary leaching solution separation technology. The device includes a housing, with a connecting rod fixedly connected to the lower surface of the housing, and a working chamber fixedly connected to the lower surface of the connecting rod. A motor is bolted to the left outer wall of the housing, and a discharge valve is fixedly connected to the lower surface of the housing. It also includes a long pin fixedly connected to the output end of the motor, with a stirring blade fixedly connected to its surface; and a fixing plate with a filter screen fixedly connected to its inner wall, the fixing plate being symmetrically distributed about the center of the filter screen, and a side plate fixedly connected to the right surface of the fixing plate. In use, the raw materials are fed into the housing, the motor is started, and the motor drives the long pin and stirring blade to rotate, completing the mixing of the raw materials and catalyst. During the rotation of the long pin, a sealing ring prevents liquid leakage from the housing.

[0004] After the leachate is mixed with the catalyst in the equipment tank, metal precipitates and is discharged along with the solution into the lower working tank for filtration. The solution and metal fall onto the filter screen in the working tank. As filtration continues, the metal accumulates on the filter screen. Subsequent solution falling onto the accumulated metal can cause splashing, which can then spray out of the working tank, polluting the working environment. Therefore, a high-efficiency purification and separation device for ternary regenerated leachate is needed to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this utility model is a high-efficiency purification and separation device for ternary regenerated leachate, comprising:

[0027] The purification and separation device includes a mixing box 10, a support column 11, and a filter box 12. The filter box 12 is placed on the ground, the support column 11 is fixed to the upper end of the filter box 12, and the mixing box 10 is fixed to the upper end of the support column 11.

[0028] The purification and separation device also includes a drain pipe 13, which is fixed inside the mixing tank 10 and connected to the mixing tank 10, with a valve installed at its lower end.

[0029] The purification and separation device also includes a first filter screen 14 and an impact column 15. The first filter screen 14 is movably connected to a limiting column inside the filter box 12, and the impact column 15 is fixed to the lower end of the first filter screen 14.

[0030] The mixing tank 10 is used to mix the leachate and the catalyst, causing the metal in the leachate to precipitate. A servo motor is installed on the mixing tank 10 to control the rotation of the internal rotating rod. At the same time, it can drive the pulley to rotate the cam on the side of the filter box 12. With the help of the spring, it can control the up and down movement of the first filter screen 14. The impact column 15 below the first filter screen 14 impacts the filter box 12 as the first filter screen 14 moves up and down, causing the metal on the first filter screen 14 to separate from the first filter screen 14, which is conducive to the falling of the solution. The support column 11 provides support and facilitates the opening of the drain pipe 13 below the mixing tank 10.

[0031] The anti-splash assembly includes a hook 20, a baffle 21, a through hole 22, an opening 23, and a first sealing door 24. The hook 20 is fixed to the bottom surface of the mixing tank 10. The through hole 22 is opened at the upper end of the baffle 21 and is hooked onto the hook 20. The opening 23 is opened in the middle of one of the baffles 21. The first sealing door 24 is hinged at the opening 23 and fixed by a mechanical lock.

[0032] The four baffles 21 fit together at the edges, and their lower ends all extend into the filter box 12;

[0033] Hook 20 serves as a connector, baffle 21 serves as a block, through hole 22 serves as a connector, opening 23 facilitates opening and closing of drain pipe 13, and first sealing door 24 serves as a seal.

[0034] Working principle:

[0035] Align the through hole 22 on the baffle 21 with the hook 20 below the mixing tank 10 and hang it up. Open the first sealing door 24 and open the valve on the drain pipe 13 through the opening 23. The liquid and metal will fall from the drain pipe 13 onto the first filter screen 14. Then close the first sealing door 24.

[0036] This step avoids prolonged operation and metal buildup on the first filter screen 14, which could cause liquid splashing. The hook 20 connection method facilitates the removal and installation of the baffle 21.

[0037] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The discharge assembly includes a second filter screen 32, an outlet 33, and a second sealing door 34. The second filter screen 32 is fixed to the upper end of the first filter screen 14. The outlet 33 is opened on the side of the filter box 12 and is inclined downward. The second sealing door 34 is hinged to the outlet 33 and fixed by a mechanical lock.

[0039] The discharge assembly also includes a first support plate 30 and a second support plate 31. The first support plate 30 and the second support plate 31 are fixed to the upper end of the first filter screen 14, and the second filter screen 32 is fixed to the upper end of the first support plate 30 and the second support plate 31, and the second filter screen 32 is inclined downward.

[0040] The discharge assembly also includes an L-shaped baffle 35, which is fixed inside the filter box 12 and located at the outlet 33.

[0041] The first support plate 30 and the second support plate 31 provide support, causing the second filter screen 32 to be tilted downwards. The second filter screen 32 is used to filter liquid, the outlet 33 is used to discharge more metal, the second sealing door 34 provides a sealing function, and the L-shaped partition 35 prevents metal from falling to the bottom of the filter box 12.

[0042] Working principle:

[0043] Liquid and metal fall from drain pipe 13 onto second filter screen 32. Liquid continues to fall to the bottom of filter box 12, while metal is trapped on second filter screen 32. As first filter screen 14 moves up and down, impact column 15 impacts filter box 12, causing vibration of first filter screen 14 and second filter screen 32. Metal trapped on second filter screen 32 is shaken off. As the tilted second filter screen 32 slides down to the side of first filter screen 14 located at outlet 33, liquid remaining on the metal continues to be filtered down by first filter screen 14. When too much metal accumulates, it will gradually move to outlet 33. L-shaped baffle 35 prevents metal from leaking into filter box 12. Open second sealing door 34 to remove accumulated metal.

[0044] This step prevents metal buildup on the second filter screen 32, further preventing liquid splashing and extending production time.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
