Description

Technical Field

[0001] This utility model relates to the field of waste battery recycling technology, specifically a waste battery recycling and purification device. Background Technology

[0002] In the process of waste battery recycling, NMP (N-methylpyrrolidone) aqueous solution is an important consumable material. In the manufacturing process of lithium batteries, NMP serves as a solvent and carrier for dispersing binders, which can improve the energy density and coating quality of lithium batteries. During the remanufacturing of lithium batteries, a large amount of waste NMP solution is generated. The waste NMP solution can be recycled and purified by heating.

[0003] For example, the patent document with announcement number CN221470918U describes an NMP recovery and purification device for improving lithium battery production. By moving the connecting plate out of the groove with a handle, the connecting plate pulls out the filter screen and moves it out of the filling box, and the impurities on the filter screen are poured out and reset. This NMP recovery and purification device for improving lithium battery production cannot collect the impurities on the filter screen in real time, which is inconvenient for subsequent recovery of the metal particles contained in the impurities.

[0004] Based on this, a waste battery recycling and purification device is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-3 As shown, a waste battery recycling and purification device includes a purification tank 101.

The side of the purification tank 101 has an output seat 105 for outputting purified MMP aqueous solution. The purification tank 101 has a filtration mechanism inside for filtering metal particles in the MMP waste solution. The side of the purification tank 101 is connected to a deposition assembly for collecting the filtered metal particles. The input seat 102 receives the MMP waste solution generated during battery recycling, the purification tank 101 filters the MMP waste solution, and the output seat 105 outputs the filtered MMP aqueous solution.

[0030] In one embodiment, such as Figure 2As shown, the filtration mechanism includes a filter barrel 103, which is located inside a purification chamber 101. A rotating block 201 is provided at one end of the filter barrel 103.

A power element for rotating the filter barrel 103 is provided at the other end of the filter barrel 103. A collection module for scraping metal particles from the filter holes of the filter barrel 103 is fixedly connected to the surface of the partition 104. MMP waste solution enters the filter barrel 103. As the filter barrel 103 rotates, the MMP waste solution passes through the filter holes on the surface of the filter barrel 103 under the action of centrifugal force. The metal particles inside the MMP waste solution gather on the surface of the filter barrel 103 under the action of centrifugal force, providing conditions for the recovery of metal particles.

[0031] In one embodiment, such as Figure 2 and Figure 3 As shown, the power element includes a first gear 202. The first gear 202 is provided on the side of the filter barrel 103. A drive device for driving the first gear 202 to rotate is provided on the upper side of the first gear 202. The first gear 202 provides the conditions for the rotation of the filter barrel 103.

[0032] In one embodiment, such as Figure 2 and Figure 3 As shown, the driving device includes a second gear 203, which is fixedly connected to the output end of a rotating motor 204. The fixed end of the rotating motor 204 is fixedly connected to the inner wall of the purification box 101. The rotating motor 204 drives the second gear 203 to rotate, which in turn drives the first gear 202 to rotate, which in turn drives the filter barrel 103 to rotate, thus providing power for the rotation of the filter barrel 103.

[0033] In one embodiment, such as Figure 4 As shown, the collection module includes a transmission trough 302. One end of the transmission trough 302 is fixedly connected to the surface of the partition 104. A scraper 301 is provided at the upper end of the transmission trough 302. The upper end of the scraper 301 is in contact with the rotating block 201. The lower end of the transmission trough 302 is connected to one end of the first pipeline 303. The rotation of the filter barrel 103 causes the scraper 301 to rub against the inner wall of the filter barrel 103. The scraper 301 scrapes away the metal particles accumulated on the surface of the filter barrel 103. The metal particles move into the transmission trough 302 under the influence of gravity, providing conditions for collecting the metal particles.

[0034] In one embodiment, such as Figure 1As shown, the deposition assembly includes a deposition tank 305, which is located on the side of the purification tank 101. The deposition tank 305 is connected to one end of a first pipeline 303. A first transmission pump 304 is installed on the first pipeline 303. A deposition tank is provided inside the deposition tank 305. A reflux device for returning MMP waste solution inside the deposition tank 305 is connected to the side of the deposition tank 305. Metal particles enter the first pipeline 303 and are powered by the first transmission pump 304. The first transmission pump 304 draws the metal particles inside the first pipeline 303 into the deposition tank 305. The metal particles are deposited in the deposition tank inside the deposition tank 305, thus separating the metal particles from the MMP waste solution.

[0035] In one embodiment, such as Figure 2 and Figure 3 As shown, the reflux component includes a second pipeline 307. One end of the second pipeline 307 is connected to the interior of the sedimentation tank 305, and the other end of the second pipeline 307 is connected to the interior of the purification tank 101. A second drive pump 306 is installed on the second pipeline 307. Power is provided by the second drive pump 306, and the MMP waste solution inside the sedimentation tank 305 is refluxed back to the interior of the purification tank 101 through the second pipeline 307, providing conditions for re-filtration of the MMP waste solution.

[0036] The above embodiment discloses a waste battery recycling and purification device, wherein the MMP waste solution generated during battery recycling is received through the input port 102, the MMP waste solution is filtered through the purification tank 101, and the MMP waste solution enters the filter barrel 103. The rotating motor 204 drives the second gear 203 to rotate, the second gear 203 drives the first gear 202 to rotate, and the first gear 202 drives the filter barrel 103 to rotate. Under the action of centrifugal force, the MMP waste solution passes through the filter holes on the surface of the filter barrel 103. The metal particles inside the MMP waste solution are aggregating on the surface of the filter barrel 103 under the action of centrifugal force, and are scraped off by the scraper 301. Metal particles accumulated on the surface of filter 103 move under gravity into the transfer tank 302. The metal particles enter the first pipeline 303 and are powered by the first transmission pump 304. The first transmission pump 304 draws the metal particles from the first pipeline 303 into the sedimentation tank 305. The metal particles are deposited in the sedimentation tank inside the sedimentation tank 305, separating the metal particles from the MMP waste solution. Powered by the second transmission pump 306, the MMP waste solution inside the sedimentation tank 305 flows back to the purification tank 101 through the second pipeline 307, where the MMP waste solution is filtered again. The filtered MMP aqueous solution is then output through the output seat 105.
