Description

Technical Field

[0001] The utility model relates to the technical field of battery pole piece production equipment, in particular to an auxiliary equipment for pole piece powder removal. Background Art

[0002] A pole piece is one of the positive and negative electrodes of a battery, usually made of metal materials such as lithium ions, cobalt, nickel, manganese, and aluminum. In a lithium battery, the pole pieces are divided into a positive pole piece and a negative pole piece. The positive pole piece is usually made of materials such as lithium compounds and lithium cobaltate, while the negative pole piece is usually made of carbon materials such as graphite. During the charge and discharge process, lithium ions move back and forth between the two pole pieces to complete the conversion and storage of electrical energy.

[0003] The main components of a lithium battery are a metal shell, positive and negative pole pieces, and a separator. Among them, the positive and negative pole pieces are respectively an aluminum foil current collector wrapped with active materials (such as lithium cobaltate, lithium manganate, and lithium iron phosphate) and a copper foil current collector wrapped with active materials (carbon materials). The active materials on the positive pole piece can be reassembled into a battery for use through a repair and regeneration method. This reasonable resource utilization can reduce pollution and relieve the pressure of mineral extraction, which is of great significance to the survival and development of humanity and the sustainability of society. The existing auxiliary equipment for pole piece powder removal can effectively separate and extract metals such as copper, aluminum, and lithium from the separator and graphite powder, improving the recovery efficiency of metal materials in waste lithium batteries.

[0004] The patent with the publication number of CN218039417U discloses a device for detaching powder from a battery pole piece. By immersing the drum assembly in a solvent pool, the solvent in the solvent pool enters the inside of the drum assembly through the mesh holes of the drum assembly. When the pole piece enters the drum assembly from the feed port, under the action of the spiral guide groove, the pole piece can be turned over and move forward towards the discharge port. The solvent entering the drum assembly can react with the pole piece powder located inside the drum assembly, so that the powder is detached. Since the drum assembly always remains at least partially immersed in the solvent pool during the turning process, that is, there is always solvent in the drum assembly, the detachment process is continuous, so that the powder can be better removed from the pole piece and the production efficiency can be improved.

[0005] However, in the comparative document, the pole piece is turned over in the drum by the rotation of the drum itself, which may cause the pole pieces to accumulate in one place and cannot contact the solvent well, so the effect of removing powder from the pole piece is not good. Content of the Utility Model

[0006] Based on this, the purpose of the present utility model is to provide an auxiliary equipment for pole piece powder removal to solve the technical problem that in the comparative document, the pole piece is turned over in the drum by the rotation of the drum itself, which may cause the pole pieces to accumulate in one place and cannot contact the solvent well, so the effect of removing powder from the pole piece is not good.

Then, in cooperation with the disturbance block and the ultrasonic instrument, the powder removal treatment is carried out on the electrode sheet. The disturbance block made of multiple groups of discs can make the electrode sheet not only rotate in the rolling barrel, but also vibrate up and down, so as to make the electrode sheet react more fully with the solvent, thereby solving the technical problem that in the comparative document, through the rotation movement of the rolling barrel itself, the electrode sheet is flipped in the rolling barrel, which may cause the electrode sheets to concentrate in one place and cannot contact the solvent well, so the powder on the electrode sheet cannot be removed well, and improving the practicability of the entire auxiliary device for electrode sheet powder removal.

[0009] The present utility model is further arranged such that a convex block is fixedly connected to one end of the fixed barrel, and a movable groove for cooperating with the convex block is provided on the rolling barrel.

[0010] By adopting the above technical solutions, the mutual cooperation between the arranged convex block and the movable groove is convenient for the rolling barrel to rotate flexibly between the fixed barrel and the liquid storage tank.

[0011] The present utility model is further arranged such that a connecting rod is fixedly connected to one side of the fixed barrel, a spring is fixedly installed at the bottom of the connecting rod, and a slot for cooperating with the connecting rod and the spring is provided in the liquid storage tank.

[0012] By adopting the above technical solutions, the mutual cooperation between the arranged connecting rod, the spring and the slot is convenient for the rolling barrel to drive the fixed barrel to move up and down together through centrifugal force while rotating, so as to cooperate with the disturbance block in the rolling barrel to make the electrode sheet better mix with the solvent in the rolling barrel.

[0013] The present utility model is further configured such that a fixing block is fixedly installed on one side of the outer side of the liquid storage tank where the slotted opening is located, and a groove for cooperating with the connecting rod is formed in the fixing block.

[0014] By adopting the above technical solution, the mutual cooperation between the provided fixing block and the groove facilitates the flexible up-and-down movement of the connecting rod, and at the same time, can prevent the solvent in the liquid storage tank from leaking.

[0015] The present utility model is further configured such that the feed pipe can movably penetrate through the baffle cover, and a discharge pipe is rotatably connected to the outer side of the transmission pipe.

[0016] By adopting the above technical solution, it is convenient for the feed pipe to move up and down in the baffle cover while the roller barrel rotates and moves up and down.

[0017] The present utility model is further configured such that a plurality of discharge ports are formed at the bottom of the liquid storage tank, and a plurality of support legs are fixedly installed on the outer side of the bottom of the liquid storage tank.

[0018] By adopting the above technical solution, when the powder on the pole piece reacts with the solvent and detaches, it can be precipitated and discharged through the discharge port, and the entire device can be erected on the ground for use through the support legs.

[0019] In summary, the present utility model mainly has the following beneficial effects:

[0028] A pole piece deflaking auxiliary device, as Figures 1-4 shown, includes a liquid storage tank 1, a baffle cover 2 is arranged on the top of the liquid storage tank 1, a shock absorber seat 6 is arranged on the top of the baffle cover 2, a motor 7 is arranged on the top of the shock absorber seat 6, a transmission pipe 11 is rotatably connected in the liquid storage tank 1, a belt 8 is arranged between the output end of the motor 7 and the transmission pipe 11, a fixed barrel 14 is movably connected in the liquid storage tank 1, a rotating barrel 12 is fixedly connected to one side of the transmission pipe 11, the rotating barrel 12 and the fixed barrel 14 are rotatably connected, a feed pipe 10 is arranged on the top of the fixed barrel 14, a solvent is arranged in the liquid storage tank 1, a disturbing block 13 is arranged in the rotating barrel 12, the transmission pipe 11 is located at a position slightly below the center point of the rotating barrel 12, the disturbing block 13 is composed of multiple groups of discs spliced together, and multiple groups of ultrasonic instruments 5 are fixedly installed on both sides in the liquid storage tank 1.

[0029] When in use, through the mutual cooperation between the feed pipe 10 and the fixed barrel 14, the pole piece is then introduced into the rotating barrel 12. Through the mutual cooperation between the arranged motor 7 and the belt 8, the rotating barrel 12 can rotate flexibly in the liquid storage tank 1, and then the pole piece is deflaked by cooperating with the disturbing block 13 and the ultrasonic instrument 5. The disturbing block 13 made of multiple groups of discs enables the pole piece to not only rotate in the rotating barrel 12 but also vibrate up and down, so as to enable the pole piece to react more fully with the solvent, thereby solving the technical problem that in the comparative document, the pole piece is flipped in the rotating barrel 12 through the rotation movement of the rotating barrel 12 itself, which may cause the pole pieces to concentrate in one place and cannot contact the solvent well, so the powder on the pole piece cannot be removed well, and the practicability of the entire pole piece deflaking auxiliary device is improved.

The whole device can be erected on the ground for use through the support legs 3.
