Technical Field

[0001] This utility model relates to the field of battery recycling and processing technology, and more specifically, to an electrolyte treatment device for battery dismantling. Background Technology

[0002] Electrolyte treatment is crucial in battery dismantling. Traditional electrolyte treatment methods often have several drawbacks. For example, some methods rely solely on simple physical filtration, which is insufficient to completely remove harmful substances from the electrolyte, and the frequent replacement of filter materials increases processing costs. Furthermore, some chemical treatment methods may generate secondary pollution, posing new environmental hazards. Simultaneously, existing processing equipment has low efficiency, failing to meet the demands of large-scale battery dismantling, thus limiting the overall efficiency of the battery recycling process.

[0003] The shortcomings of the existing device are as follows: In the electrolyte treatment and filtration stage, the existing device requires an additional power unit for the filtration mechanism, which increases equipment and operating costs. At the same time, the filtration mechanism lacks an automatic cleaning mechanism, the filter components are prone to clogging, reducing filtration efficiency and requiring frequent replacement, which affects stability and treatment quality. In addition, it is difficult to achieve continuous electrolyte treatment, requiring intermittent operation, resulting in low work efficiency and failing to meet the needs of rapid electrolyte treatment in large-scale battery dismantling. Utility Model Content

[0004] The purpose of this invention is to provide an electrolyte treatment device for battery disassembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrolyte treatment device for battery disassembly, comprising a housing, an inner bore weir plate fixedly installed on the lower inner wall of the housing, an outer bore weir plate fixedly installed inside the middle part of the housing, a filtration mechanism installed below the outer bore weir plate on the housing, and a centrifugal separation mechanism installed above the outer bore weir plate on the housing.

[0006] As a preferred technical solution of this utility model, the filtration mechanism includes a first rotating rod rotatably mounted at the center below the outer bore weir plate via a bearing. The bottom end of the first rotating rod passes through a through hole in the middle of the inner bore weir plate and is rotatably mounted at the center of the bottom of the housing via a bearing. An impeller is fixedly installed between the inner bore weir plate and the bottom of the housing via the first rotating rod. An inlet is provided through the bottom of the housing facing the impeller.

[0007] As a preferred embodiment of this utility model, a pair of connecting columns are fixedly installed on both sides of the first rotating rod between the inner and outer bore weir plates. The connecting columns have cavities inside and slide rods are slidably connected. A scraper is fixedly connected between the ends of the pair of slide rods.

[0008] As a preferred technical solution of this utility model, the filtration mechanism includes a motor fixedly installed on the top of the housing, the output end of the motor passing downward through the top of the housing via a second rotating rod, a rotating drum fixedly installed at the bottom end of the second rotating rod, a liquid collection port being opened at the center of the bottom of the rotating drum, and three sets of sealing rings installed on the outer wall of the rotating drum from top to bottom.

[0009] As a preferred technical solution of this utility model, a baffle plate is provided inside the drum and above the liquid collection port. The baffle plate is fixedly connected to the top of the inner side of the drum by a connecting rod.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] (1) When the electrolyte enters the device through the inlet, the impact impeller drives the first rotating rod to rotate, so that no additional power is needed to drive the filter mechanism. When the first rotating rod rotates, it drives the scraper to move along the inner wall of the filter cylinder. The spring can keep the scraper in close contact with the inner wall of the filter cylinder, effectively scraping away impurities on the inner wall of the filter cylinder, preventing impurities from clogging the filter cylinder, ensuring the continuity and stability of the filtration effect, extending the service life of the filter cylinder, and reducing the frequency of replacing filter components.

[0012] (2) This device drives the second rotating rod to rotate the drum at high speed by the motor, and uses centrifugal force to separate different phase substances (light phase and heavy phase) in the electrolyte, realizing the efficient separation of different phase substances and providing convenience for subsequent electrolyte recovery and treatment.

[0013] (3) This device can continuously enter the electrolyte from the inlet, filter impurities through the filtration mechanism, and then enter the centrifugal separation mechanism for phase separation. Finally, substances of different phases are discharged through the light phase outlet and the heavy phase outlet respectively, realizing continuous processing, improving working efficiency, and meeting the needs of electrolyte treatment in the process of large-scale battery dismantling.

[0021] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0022] Please see Figure 1-4 According to an embodiment of the present invention, an electrolyte treatment device for battery disassembly includes a housing 1, an inner hole weir plate 2 fixedly installed on the lower inner wall of the housing 1, an outer hole weir plate 3 fixedly installed inside the middle part of the housing 1, a filter mechanism 4 installed below the outer hole weir plate 3 on the housing 1, and a centrifugal separation mechanism 5 installed above the outer hole weir plate 3 on the housing 1.

[0023] The housing 1 serves as the outer shell of the entire device, providing installation space and protection for other components. The outer weir plate 3, in conjunction with the inner weir plate 2, divides the space and guides the electrolyte flow path.

[0024] In this embodiment, the filtration mechanism 4 includes a first rotating rod 6 rotatably mounted at the center below the outer bore weir plate 3 via a bearing. The bottom end of the first rotating rod 6 passes through the through hole in the middle of the inner bore weir plate 2 and is rotatably mounted at the center of the bottom of the housing 1 via a bearing. An impeller 7 is fixedly mounted between the inner bore weir plate 2 and the bottom of the housing 1. An inlet 8 is opened through the bottom of the housing 1 facing the impeller 7.

[0025] Among them, the impeller 7 drives the first rotating rod 6 to rotate under the impact of the electrolyte.

[0026] In this embodiment, a pair of connecting columns 9 are fixedly installed on both sides of the first rotating rod 6 between the inner hole weir plate 2 and the outer hole weir plate 3. The connecting columns 9 have cavities inside and slide rods 10 are slidably connected. A scraper 11 is fixedly connected between the ends of the pair of slide rods 10. A spring 12 is fixedly connected between the scraper 11 and the connecting column 9 and wraps around the slide rod 10. A filter cylinder 13 is fixedly installed between the inner hole weir plate 2 and the outer hole weir plate 3. The inner wall of the filter cylinder 13 is in contact with the scraper 11.

[0027] The connecting column 9 provides sliding space for the slide bar 10. The slide bar 10 allows the scraper 11 to rotate with the first rotating rod 6 and move flexibly. The scraper 11 scrapes away impurities from the inner wall of the filter cylinder 13 to prevent clogging. The spring 12 ensures that the scraper 11 is always in close contact with the inner wall of the filter cylinder 13.

[0028] In this embodiment, the filtration mechanism 4 includes a motor 14 fixedly installed on the top of the housing 1. The output end of the motor 14 passes through the top of the housing 1 via a second rotating rod 15. A rotating drum 16 is fixedly installed at the bottom of the second rotating rod 15. A liquid collection port 17 is opened at the center of the bottom of the rotating drum 16. Three sets of sealing rings 18 are installed on the outer wall of the rotating drum 16 from top to bottom.

[0029] The second rotating rod 15 transmits the power of the motor 14 to the rotating drum 16, which rotates at high speed to achieve centrifugal separation of the electrolyte.

[0030] In this embodiment, a baffle plate 19 is provided inside the drum 16 and above the liquid collection port 17. The baffle plate 19 is fixedly connected to the top of the inner side of the drum 16 by a connecting rod 20. A light phase channel 21 is opened on the top wall of the drum 16 near the connecting rod 20 and extends to the outer side wall of the drum 16. A heavy phase channel 22 is opened on the top wall of the drum 16 away from the connecting rod 20 and extends to the outer side of the top of the drum 16. A heavy phase outlet 23 is opened on the top of the outer side of the housing 1. A light phase outlet 24 is opened on the outer side of the housing 1 above the middle sealing ring 18.

[0031] The baffle 19 alters the flow path of the electrolyte within the drum 16, facilitating phase separation. The light phase channel 21 is the channel for discharging the light phase material from the drum 16. The heavy phase channel 22 is the channel for discharging the heavy phase material from the drum 16. The heavy phase outlet 23 is the outlet for the heavy phase material discharge device. The light phase outlet 24 is the outlet for the light phase material discharge device.

[0032] In practical applications, the electrolyte is first pumped from the collection point to the inlet 8 at the bottom of the housing 1. Since the inlet 8 faces the impeller 7, the impeller 7 begins to rotate under the impact of the electrolyte. The electrolyte then flows upwards through the inner weir plate 2, and then further upwards through the filter cylinder 13. The filter cylinder 13 filters the electrolyte, removing impurities. Simultaneously, the rotation of the impeller 7 drives the first rotating rod 6 to rotate, and the connecting columns 9 installed on both sides of the first rotating rod 6 rotate accordingly. The connecting columns 9 drive the scraper 11 to rotate via the slide rod 10. Under the action of the spring 12, the scraper 11 remains tightly pressed against the inner wall of the filter cylinder 13. The rotating scraper 11 continuously scrapes away impurities adhering to the inner wall of the filter cylinder 13, preventing impurities from clogging the filter cylinder 13 and ensuring the continuity of the filtration effect. Stability: After filtration, the electrolyte continues to flow upward through the outer weir plate 3, and then enters the drum 16 through the liquid collection port 17. The start motor 14 drives the drum 16 to rotate at high speed through the second rotating rod 15. The baffle plate 19 changes the flow path of the electrolyte entering the drum 16, so that the electrolyte forms a flow state more conducive to phase separation in the drum 16. Under the action of centrifugal force generated by the high-speed rotation of the drum 16, the different phase substances (light phase and heavy phase) in the electrolyte begin to separate. The light phase substances gradually approach the center of the drum 16, while the heavy phase substances are thrown to the outside of the drum 16. The separated light phase substances are discharged from the drum 16 through the light phase channel 21 and then discharged from the device through the light phase outlet 24. The heavy phase substances are discharged from the drum 16 through the heavy phase channel 22 and finally discharged from the device through the heavy phase outlet 23.
