Description

Technical Field

[0001] The invention relates to the technical field of regeneration of useful parts of waste batteries, in particular to a device for separating positive electrode materials and aluminum foil of lithium batteries. Background Art

[0002] Lithium batteries are mainly composed of five parts: positive electrode, negative electrode, separator, electrolyte and shell. There is an aluminum foil isolation layer between the electrolyte and the positive electrode material. The aluminum foil carries the positive electrode active material and collects and conducts the generated current to the external circuit to realize the conversion of chemical energy into electrical energy. Aluminum foil is a valuable resource. It can be separated from the positive electrode material by separation equipment, and the aluminum foil and the positive electrode material can be recycled separately, which helps to achieve effective recycling of resources.

[0003] The existing separation equipment still has the following defects after use:

[0004] 1. When separating the positive electrode material and the aluminum foil, the separation liquid is generally heated to speed up the separation of the positive electrode material and the aluminum foil. However, this method generally heats the separation liquid comprehensively. If the heating time is too long, it is easy to damage the positive electrode material or oxidize the aluminum foil, which loses its value for recycling. If temperature control is performed, it takes a long time to keep the overall temperature of the separation liquid in a constant temperature state, which makes it easy for the separation liquid in different areas to have different temperatures during the temperature control process, resulting in different temperatures and affecting the separation effect.

[0005] 2. During the separation process, the positive electrode material and the aluminum foil after cleaning are generally placed directly into the separation liquid for separation. However, after separation, the positive electrode material and the aluminum foil need to be salvaged and cleaned again. Since the positive electrode material and the aluminum foil sink to the bottom of the separation liquid after separation, and the aluminum foil floats on the surface of the separation liquid, and due to the lack of limiting measures during the separation process, the positive electrode material and the aluminum foil change position with the flow of the separation liquid during salvage, thereby increasing the difficulty of salvaging the positive electrode material and the aluminum foil, and prolonging the processing time of the positive electrode material and the aluminum foil. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a device for separating lithium battery positive electrode materials and aluminum foil, which can effectively solve the problems in the prior art that the temperature of the separation liquid in different areas is different during the temperature control process, affecting the separation effect, and the lack of limiting measures during the separation process, which increases the difficulty of salvaging the positive electrode material and aluminum foil.

[0048] Compared with the prior art, the present invention can control the separation area when the positive electrode material and the aluminum foil are separated, which is beneficial to the centralized processing of the positive electrode material and the aluminum foil by the processing material, reduces material loss, controls the temperature of the separation area and keeps impurities away from the separation box 31, and at the same time limits the positive electrode material and the aluminum foil to prevent them from flowing to other areas. During separation, the solvent flows out from the inside of the processing block 619 and diffuses around with the separation box 31 as the center. The separation component and the multi-layer control mechanism can be installed on different processes, with a wide range of applications, thereby improving the practicability of the separation component and the multi-layer control mechanism.

[0049] Working principle:

[0050] Initial limit:

[0051] Before using the present invention, the user needs to manually rotate the integrated sealing plug at the top of the storage box 69 counterclockwise. Since the integrated sealing plug is threadedly connected to the top of the storage box 69, the integrated sealing plug gradually separates from the top of the storage box 69 by relying on the thread when rotating counterclockwise. When the integrated sealing plug is completely separated from the top of the storage box 69, the user uses a funnel or other tool to inject the solvent into the storage box 69 from the connection between the integrated sealing plug and the top of the storage box 69. At this time, the state of the blocking block 610 is as follows: Figure 4 As shown, the blocking block 610 blocks the agent guiding tube 611;

[0052] After the solvent injection is completed, the user places the integrated sealing plug on the connection and turns the integrated sealing plug clockwise to restore the integrated sealing plug to Figure 4 Status shown;

[0053] The user needs to connect an external motor to the end of the drive shaft 62 away from the worm 63, and the motor serves as the driving source of the drive shaft 62;

[0054] The user needs to connect an external hot air source to the air duct 613, and the hot air source is in a closed state at this time;

[0055] The user needs to connect the integrated outlet pipe to an external control valve. At this time, the control valve is in a closed state, and separation liquid is already stored in the ultrasonic separation box 1;

[0056] Discharging steps:

[0057] First, the user needs to manually or use a lifting tool to move the mounting bracket 2 out of the top of the ultrasonic separation box 1, and then manually rotate the driving block 33 counterclockwise after moving it out. When the driving block 33 rotates counterclockwise, it simultaneously drives the positioning rod 34 to rotate counterclockwise. Fig.10 As shown, since the positioning rod 34 is threadedly connected to the side of the positioning seat 32 close to the driving block 33, when the positioning rod 34 rotates counterclockwise, it gradually separates from the side of the positioning seat 32 close to the driving block 33 by relying on the thread. When the positioning rod 34 separates from the side of the positioning seat 32 close to the driving block 33, it simultaneously drives the positioning column 35 to separate from the cylindrical groove. When the positioning column 35 separates from the cylindrical groove, it simultaneously drives the arc block 37 to separate from the arc groove. Fig.10 and Fig.11As shown, when the arc block 37 is separated from the arc groove, it will be pressed by the inner wall of the cylindrical groove, so that the arc block 37 is squeezed into the positioning column 35. When the arc block 37 is squeezed into the positioning column 35, the spring 36 is pressed simultaneously, causing the spring 36 to deform. When the user rotates the positioning rod 34 counterclockwise for five to six turns, at this time, more than half of the surface of the positioning rod 34 is presented on the side of the positioning seat 32 close to the driving block 33, and the positioning column 35 and the arc block 37 have completely separated from the cylindrical groove. Then the user lifts the positioning block 5 upward, so that the multi-layer control mechanism is completely separated from the separation component, so that the baffle 4 is away from the top of the separation box 31, which is convenient for the user to place the positive electrode material and aluminum foil to be separated in the separation box 31. After the user places the required separation material in the separation box 31, the above steps are reversed again to restore the multi-layer control mechanism and the separation component to Figure 3 and Figure 4 In the state shown, by placing the positive electrode material and the aluminum foil inside the separation box 31, the positive electrode material and the aluminum foil can be limited during separation to prevent them from changing position with the flow of the separation liquid during separation;

[0058] Then, the steps of the above-mentioned mounting frame 2 are reversed so that the bottom end of the mounting frame 2 is re-inserted into the top end of the ultrasonic separation box 1 along the insertion position of the top end of the ultrasonic separation box 1, so that the mounting frame 2 is restored to Figure 3 In the state shown, the separation liquid inside the ultrasonic separation box 1 enters the separation box 31 through the processing hole, thereby controlling the separation area of ​​the positive electrode material and the aluminum foil, so that they are separated inside the separation box 31, and then by controlling the separation area, the subsequent processing can concentrate the solvent to treat the surface of the positive electrode material and the aluminum foil, avoiding unnecessary material waste during the processing, and the positive electrode material and the aluminum foil will not flow to other areas with the separation liquid during the separation process through the blocking of the baffle 4 and the limiting of the separation box 31, so that the positive electrode material and the aluminum foil are always located inside the separation box 31, which is convenient for the subsequent salvage of the positive electrode material and the aluminum foil, thereby reducing the salvage time of the positive electrode material and the aluminum foil, reducing resource waste, and improving the recovery rate of the positive electrode material and the aluminum foil;

[0059] Separation steps:

[0060] The user turns on the power of the ultrasonic separation box 1 to start the ultrasonic separation box 1 to increase the force applied by the separation liquid to the positive electrode material and the aluminum foil during the separation process through the ultrasonic principle of the ultrasonic separation box 1, so that the positive electrode material and the aluminum foil are separated, and the hot air source is turned on, and the hot air in the hot air source flows into the inside of the air guide pipe 613, and the hot air flows from the inside of the air guide pipe 613 into the drainage cavity in the conduit 612 and the inside of the connecting pipe 614, as shown in FIG. Figure 6 , Figure 7 and Figure 8As shown, the hot air flows from the drainage cavity in the conduit 612 into the drainage cavity in the control tube 615, and the hot air flows from the drainage cavity in the control tube 615 into the drainage cavity in the processing tube 618. The hot air enters the inner cavity of the processing block 619 through the introduction hole from the drainage cavity in the processing tube 618, and then the hot air is introduced into the separation liquid in the separation box 31 through the drainage hole, and the separation liquid in the separation box 31 is heated again. Figure 6 As shown, the hot air enters the air guide cavity in the baffle 4 from the connecting pipe 614, and the hot air is introduced from the air guide cavity in the baffle 4 to the heating cavity in the separation box 31, and then the hot air heats the inner wall of the separation box 31, so that the heated inner wall of the separation box 31 double heats the separation liquid inside the separation box 31, as shown in FIG. Fig. 9 As shown, since part of the processing hole is located inside the heating chamber, the separation liquid will be preheated in the process of entering the separation box 31 through the processing hole. By preheating the separation liquid in the processing hole, heating the inner wall of the separation box 31, and heating the separation liquid inside the separation box 31 by using the drainage hole on the processing block 619, two heating modes of inward contraction and outward diffusion with the separation box 31 as the center are formed, which is conducive to accelerating the heating speed of the separation liquid inside the separation box 31. In the case of double heating, the separation liquid around the separation box 31 can be preheated through the outer wall of the separation box 31, thereby increasing the temperature of the separation liquid around the separation box 31, and then the separation liquid around the separation box 31 can enter the separation box 31 with its own preheated temperature, which can reduce the heating time of the separation liquid entering the separation box 31.

[0061] The user turns on the motor power supply to start the motor working. The output shaft of the motor drives the drive shaft 62 to rotate clockwise. When the drive shaft 62 rotates clockwise, it synchronously drives the worm 63 to rotate clockwise. Figure 4 and Figure 5As shown, since the transmission column 617 is arranged between every two arc-shaped teeth on the worm 63, and the transmission wheel 616 is rotatably connected with the transmission column 617, when the worm 63 rotates clockwise, the transmission column 617 is synchronously pushed to rotate clockwise, and when the transmission column 617 rotates clockwise, the transmission wheel 616 is synchronously driven to rotate clockwise, and when the transmission wheel 616 rotates clockwise, the control tube 615 is synchronously driven to rotate clockwise, and when the control tube 615 rotates clockwise, the processing tube 618 is synchronously driven to rotate clockwise, and when the processing tube 618 rotates clockwise, the processing block 619 is synchronously driven to rotate clockwise, thereby driving the separation box The separation liquid flows inside the separation box 31, so that the separation liquid inside the separation box 31 is guided out of the separation box 31 through the processing hole, so that the separation liquid around the separation box 31 flows into the separation box 31 with the separation liquid inside the separation box 31, and then the separation liquid temperature inside the separation box 31 is controlled to avoid the separation liquid temperature in the same area being too high, thereby preventing material damage, and when the separation liquid is replaced, the impurities separated from the surface of the positive electrode material and the aluminum foil flow with the separation liquid and the impurities are guided out of the separation box 31 through the processing hole, so as to prevent the impurities from being adsorbed on the surface of the positive electrode material and the aluminum foil for the second time, thereby improving the separation effect of the positive electrode material and the aluminum foil;

[0062] like Figure 4 As shown, the worm 63 synchronously drives the transmission rod 64 to rotate clockwise when it rotates clockwise. Since the transmission rod 64 is rotationally connected with the transmission frame 65, the transmission frame 65 is slidably connected with the control plate 66, and the control plate 66 is slidably connected to the inside of the drive box 61, the transmission frame 65 is synchronously driven to slide on the surface of the control plate 66 when the transmission rod 64 rotates clockwise, and the control plate 66 is synchronously lifted when the transmission frame 65 slides on the surface of the control plate 66, so that the control plate 66 moves upward. When the control plate 66 moves upward, it synchronously drives the transmission block 67 to move upward. When the transmission block 67 moves upward, it synchronously drives the driving frame 68 to move upward. When the driving frame 68 moves upward, it synchronously drives the blocking block 610 to move upward. When the blocking block 610 moves upward, it is synchronously moved out of the inside of the agent guide tube 611, thereby releasing the blocking of the blocking block 610 on the connection between the agent guide tube 611 and the agent storage box 69, so that the solvent in the agent storage box 69 is discharged through the agent guide tube 611. Figure 6 As shown, the solvent is introduced from the inside of the guide tube 611 into the inside of the catheter 612, the solvent is introduced from the inside of the catheter 612 into the inside of the control tube 615, and the solvent is introduced from the inside of the control tube 615 into the inside of the processing tube 618. Since the separation liquid on the inner wall of the ultrasonic separation box 1 enters the inside of the separation box 31 through the processing hole, and the separation liquid inside the separation box 31 enters the inner cavity of the processing block 619 through the drainage hole on the outer surface of the processing block 619, the separation liquid enters the processing tube 618 through the inner cavity of the processing block 619 and mixes with the solvent, and when the processing block 619 continues to rotate clockwise, as shown in FIG. Figure 7As shown, the mixed separation liquid diffuses into the separation box 31 with the processing tube 618 as the center by means of the rotation force, so that the solvent contacts the positive electrode material and the aluminum foil, and contacts all the positive electrode materials and aluminum foils in the separation box 31 in the form of diffusion from the center to the periphery, avoiding the situation that some positive electrode materials and aluminum foils cannot contact the solvent;

[0063] like Figure 4 As shown, after the transmission rod 64 rotates 180 degrees, the transmission rod 64 continues to rotate, causing the end of the transmission rod 64 close to the transmission frame 65 to gradually move away from the control plate 66, so that the end of the transmission rod 64 close to the transmission frame 65 will synchronously drive the transmission frame 65 away from the control plate 66 when it moves away from the control plate 66, and the transmission frame 65 will synchronously drive the control plate 66 to move downward when it moves away from the control plate 66, so that the blocking block 610 moves downward, and the transmission principle of the control plate 66 and the blocking block 610 is consistent with the above. The blocking block 610 blocks the connection between the agent guide tube 611 and the agent storage box 69 again during the downward movement, thereby controlling the volume of the solvent entering the inside of the conduit 612, thereby realizing quantitative delivery of the solvent, and during the delivery process, the conduit 612, the control tube 615 and the drainage cavity of the processing tube 618 can be heated, which can reduce the viscosity between the solvent and the separation liquid, reduce the flow resistance of the solvent to the positive electrode material and the aluminum foil, and thus improve the separation efficiency of the positive electrode material and the aluminum foil, thereby preventing the occurrence of excessive solvent delivery and affecting the separation effect;

[0064] It should be noted that: after the separation of the positive electrode material and the aluminum foil is completed, the steps of disengaging the mounting frame 2 from the top of the ultrasonic separation box 1 and disengaging the positioning block 5 from the positioning seat 32 are performed again. Normally, the surface separation liquid needs to be cleaned off after the positive electrode material and the aluminum foil are separated. At this time, the user can install it on the subsequent cleaning equipment after separation for cleaning, thereby further expanding the scope of use of the separation component and the multi-layer control mechanism, and helping to improve the practicality of the separation component and the multi-layer control mechanism.
