Description

Technical Field

[0002] With the increasing global awareness of sustainable development, the rare metal resources such as cobalt, nickel, and lithium contained in waste batteries not only have high economic value, but also have important significance for reducing environmental pollution and realizing resource recycling. At present, the demand for battery recycling at home and abroad is gradually increasing. In the process of battery recycling, the stripping machine, as one of the key equipment, is mainly used for the preliminary treatment of battery pole pieces, that is, to strip the electrode material (such as black powder) from the pole piece. The working principle of the stripping machine is to separate the active material on the pole piece from the current collector by physical crushing, so as to facilitate the subsequent deep recycling and treatment. There are many types of crushers on the market, but the main one is the hammer crusher. Its working principle is to hit the pole piece with a high-speed rotating hammer head, so as to achieve the purpose of crushing and stripping. However, the hammer crusher has certain limitations. The hammer crushing efficiency is less than 95%, especially when dealing with some pole pieces with strong adhesion. The stripping effect of black powder is not good, and it is difficult to efficiently strip the black powder on the pole piece. In addition, due to the structural characteristics of the hammer crusher, it is easy to wear under long-term operation, resulting in high equipment maintenance costs. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] like Figures 1 to 3 As shown, the utility model provides a pole powder stripping machine, including a chassis 1, a stripping assembly 2 and a driving assembly 3. The chassis 1 has a stripping chamber 11, a feed port 12 and a discharge port. The feed port 12 and the discharge port are respectively connected to the stripping chamber 11. The material (i.e., the pole piece of the waste battery) enters the stripping chamber 11 from the feed port 12. The stripping chamber 11 is used to accommodate the material in the stripping process. The processed material, including the stripped pole piece and the separated pole powder, is discharged from the discharge port; the stripping assembly 2 includes a main shaft 21, a friction plate structure 22 and a driving assembly 3. and hammer structure 23, the main shaft 21 is installed in the stripping chamber 11, one end of the main shaft 21 is connected to the driving assembly 3, the friction plate structure 22 is arranged at one end of the main shaft 21, and the feed port 12 is located at the end of the stripping chamber 11 close to the friction plate structure 22, so as to generate friction through high-speed rotation, so that the pole powder on the surface of the pole piece is loosened due to friction, the hammer structure 23 is arranged at the other end of the main shaft 21, and the discharge port is located at the end of the stripping chamber 11 close to the hammer structure 23, which is used for knocking and cutting the material, thereby further promoting the separation of the pole powder and the pole piece.

[0024] Based on the above structure, when the pole pieces enter the stripping chamber 11 from the feed port 12, they first contact the friction plate structure 22. The high-speed rotating friction plate structure 22 contacts the surface of the pole piece, generating friction, causing the pole powder on the pole piece to begin to loosen. Subsequently, the pole piece continues to advance to the area where the hammer structure 23 is located. The hammer structure 23 further destroys the pole piece structure through the knocking action, causing the pole powder to completely separate from the pole piece matrix. The pole powder stripping machine is a device specially designed for efficiently stripping pole powder from waste battery pole pieces. This embodiment effectively removes the pole powder containing valuable metals from the battery pole piece by combining the two physical forces of friction and knocking, and finally discharges it from the discharge port, where the pole powder can be collected and recycled, and the base material (such as copper foil or aluminum foil) can also be further processed or recycled, solving the problem that the existing hammer crusher cannot efficiently strip the pole powder.

[0025] In some embodiments, the friction plate structure 22 includes a plurality of first friction plate groups 221, and the first friction plate group 221 forms an angle with the axis of the main shaft 21, so as to maximize the friction force by increasing the contact surface and changing the contact angle when the pole piece passes through the stripping machine, thereby more effectively stripping the black powder from the pole piece. It can also be understood that the first friction plate group 221 not only increases the friction force, but also helps to push the material (pole piece) forward, ensuring that the material can be smoothly moved from the feed port 12 to the position of the hammer structure 23, and receive subsequent processing by the hammer structure 23.

[0026] In addition, multiple first friction plate groups 221 are arranged at intervals around the axis of the main shaft 21, so that the pole piece will be subjected to continuous and uniform friction when passing through the stripping cavity 11, ensuring that each part of the pole piece can be fully friction-treated and avoiding the problem of insufficient local treatment.

[0027] like Figure 4 As shown, the first friction plate group 221 includes a plurality of first friction plates 2211 and a first mounting seat 2212. The plurality of first friction plates 2211 are detachably mounted on the main shaft 21 through the corresponding first mounting seats 2212, which ensures the stability of the first friction plates 2211 and facilitates the replacement of worn first friction plates 2211, making maintenance convenient. The plurality of first friction plates 2211 are spaced apart along the length direction of the main shaft 21, ensuring that the pole plates can be subjected to continuous and uniform friction when passing through.

[0028] Based on the above structure, the first friction plate 2211 of this embodiment generates necessary friction force by contacting with the pole piece to help peel off the black powder on the pole piece, and the first friction plates 2211 arranged at intervals ensure that each part of the pole piece surface can be subjected to sufficient friction, thereby improving the black powder peeling efficiency. In addition, when the pole piece passes through the above first friction plate 2211, it will be slightly pushed forward, which helps the material to move smoothly in the stripping chamber 11.

[0029] It should be noted that the first friction plate 2211 of the present embodiment is of a detachable structure, which is convenient for replacement. In addition, it is made of 60Si2Mn material, which has better wear resistance, strength and corrosion resistance.

[0030] In some embodiments, the friction plate structure 22 includes multiple second friction plate groups 222, and the second friction plate group 222 is arranged parallel to the axis of the main shaft 21. Compared with the first friction plate group 221, the parallel arrangement of the second friction plate group 222 can increase the contact area between the pole plate and the friction plate, thereby increasing the friction force and ensuring that the pole plate has enough time to fully contact with the friction plate when passing through the stripping machine, thereby improving the black powder stripping rate and helping to more thoroughly strip the black powder on the pole plate.

[0031] In addition, multiple second friction plate groups 222 are arranged at intervals around the axis of the main shaft 21, ensuring that the pole piece can be continuously and evenly subjected to friction when passing through the stripping machine, and a second friction plate group 222 is arranged between two adjacent first friction plate groups 221, ensuring that the pole piece can be subjected to appropriate types of friction treatment at different stages, which helps to improve the overall uniformity of material processing and reduce the problem of insufficient or excessive local processing.

[0032] In some embodiments, the second friction plate group 222 includes a plurality of second friction plates 2221 and a second mounting seat 2222. The plurality of second friction plates 2221 are detachably mounted on the main shaft 21 through corresponding second mounting seats 2222, thereby ensuring the stability and replaceability of the friction plates. The plurality of second friction plates 2221 are spaced apart along the length direction of the main shaft 21, thereby ensuring that the pole piece can be continuously subjected to friction treatment when passing through the stripping machine, while avoiding local overheating or wear problems that may be caused by continuous and intensive friction.

[0033] It should be noted that the second friction plate 2221 of the present embodiment is of a detachable structure, which is convenient for replacement. In addition, it is made of 60Si2Mn material, which has better wear resistance, strength and corrosion resistance.

[0034] In some embodiments, the hammer structure 23 includes multiple disks 231, multiple pins 232 and multiple hammers 233. The multiple disks 231 are sleeved on the circumference of the main shaft 21, and the multiple disks 231 are spaced apart along the length direction of the main shaft 21 to form a stable support structure and an installation space for the hammers 233. The pins 232 pass through each disk 231 in turn, and the hammers 233 are connected to the corresponding pins 232. The pins 232 are spaced apart around the axis of the main shaft 21, thereby ensuring the reasonable distribution of the hammers 233 in space and facilitating uniform force application.

[0035] Based on the above structure, by evenly distributing the hammer pieces 233 on the disc 231, the hammer piece structure 23 can evenly apply force on the pole piece, avoid local stress concentration, ensure the uniformity and efficiency of the stripping process, and through the rotation of the main shaft 21, the hammer piece 233 rotates accordingly, exerting impact force on the pole piece to strike and hammer it, thereby achieving the stripping of the black powder.

[0036] In some embodiments, two hammers 233 are provided on the same pin shaft 232 located in the same installation space, which can cover a wider width of the pole piece, thereby increasing the contact area with the pole piece and improving the stripping efficiency of the black powder. The two hammers 233 are arranged at intervals to ensure that the two hammers 233 do not interfere with each other during rotation, while also covering a wider processing area and improving the stripping efficiency.

[0037] In some embodiments, it also includes a frame 4, which is the basic frame of the entire device and provides structural support. The chassis 1 is installed on the frame 4. The chassis 1 includes a first shell 13 and a second shell 14. The first shell 13 is connected to the second shell 14 to form a stripping chamber 11. The first shell 13 has a feed port 12, and the second shell 14 has a discharge port. The bottom wall of the first shell 13 is provided with a plurality of ribs 15 arranged at intervals along the length direction of the first shell 13, and the plurality of ribs 15 are staggered, which increases the friction of the electrode when it slides in the stripping chamber 11, and helps to more effectively strip the black powder from the electrode. A screen is provided at one end of the discharge port close to the stripping chamber 11 to screen and separate the stripped material to ensure that only black powder particles that meet the size requirements can pass through, while larger electrode fragments or other impurities are blocked to improve the purity of the final product.

[0038] In some embodiments, the second shell 14 includes an upper shell 141, a lower shell 142, a rotating shaft pin 143, an electric push rod 144 and a first driving member 145. The lower shell 142 is installed on the frame 4, the upper shell 141 and the lower shell 142 are rotatably connected through the rotating shaft pin 143, one end of the electric push rod 144 is connected to the upper shell 141, and the other end of the electric push rod 144 is connected to the first driving member 145 to drive the upper shell 141 to rotate relative to the lower shell 142.

[0039] Based on the above structure, the upper shell 141 of this embodiment is rotatably connected to the lower shell 142 through the rotating shaft pin 143, and through the control of the second driving member 31, the electric push rod 144 is used to drive the upper shell 141 to rotate relative to the lower shell 142 to realize automatic opening and closing operation. This design allows the upper shell 141 to be opened and closed relative to the lower shell 142, improves the accessibility and visibility inside the equipment, facilitates regular inspection, cleaning and replacement of worn parts, and reduces maintenance difficulty and time cost.

[0040] The first housing 13 of this embodiment includes a top cover and a bottom cover, which are enclosed together to form the first housing.

[0041] In some embodiments, the drive assembly 3 includes a second drive member 31, a driving wheel, a driven wheel and a synchronous belt. The output shaft of the second drive member 31 is connected to the driving wheel so that the driving wheel receives power from the second drive member 31 and converts it into rotational motion. The driven wheel and the driving wheel are synchronously linked through a synchronous belt. One end of the main shaft 21 is connected to the driven wheel to further transmit the rotational power transmitted from the driving wheel to the main shaft 21, thereby driving the friction plate structure 22, the hammer structure 23 and other components to rotate.

[0042] In summary, the embodiment of the utility model provides a pole powder stripping machine. When the pole pieces enter the stripping chamber 11 from the feed port 12, they first contact the friction plate structure 22. The high-speed rotating friction plate structure 22 contacts the surface of the pole piece, generating friction, causing the pole powder on the pole piece to begin to loosen. Subsequently, the pole piece continues to advance to the area where the hammer structure 23 is located. The hammer structure 23 further destroys the pole piece structure through the knocking action, causing the pole powder to completely separate from the pole piece matrix. The pole powder stripping machine is a device specially designed for efficiently stripping pole powder from waste battery pole pieces. This embodiment effectively removes pole powder containing valuable metals from battery pole pieces by combining the two physical forces of friction and knocking, and finally discharges it from the discharge port, wherein the pole powder can be collected and recycled, and the base material (such as copper foil or aluminum foil) can also be further processed or recycled, solving the problem that the existing hammer crusher cannot efficiently strip pole powder.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
