Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] See Figure 1 As shown, a waste carbon brush cleaning device includes an outer shell 1 with a certain accommodating space, which contains cleaning fluid. An inner shell is detachably connected to the outer shell 1 and has holes. Waste carbon brushes are loaded inside the inner shell, which also has holes. A crank handle 9 is installed outside the inner shell, and a stirring component is installed inside the inner shell. In use, the inner shell is loaded onto the outer shell 1 and immersed in the cleaning fluid. The inner shell is cranked by hand to start the stirring component, and the cleaning fluid cleans the waste carbon brushes inside the inner shell to a certain extent.

[0029] The outer shell 1 has an upper opening and a drain outlet 2 is provided on the outer shell 1. The outer shell 1 is connected to the inner shell through a shaft 3. The inner shell can be rotated and the extension line of the shaft 3 is located above the center position of the inner shell. The inner shell includes two hemispherical covers. Each cover has a hole, and the central axis of the hole is parallel to the central axis of the inner shell. The two covers are specifically divided into an upper cover 4 and a lower cover 5. The upper cover 4 is at a high position and the opening of the upper cover 4 faces downward. The lower cover 5 is at a low position. The opening of the upper cover is provided with an external thread, and the opening of the lower cover is provided with an internal thread. The openings of the upper cover and the lower cover can be connected to form a spherical whole with a hollow interior. Two connecting plates 6 are provided on the outer side of the upper opening of the lower cover 5. The two connecting plates 6 are symmetrically distributed on the vertical central axis of the lower cover 5. The connecting plates 6 are connected to the inner end of the shaft 3, and the outer end of the shaft 3 is movably connected to the outer shell 1. The connection structure between the outer end of the shaft 3 and the outer shell 1 is as follows.

[0030] The outer end of the shaft 3 is connected to an anti-detachment plate 7, which has a circular cross-section. Two first grooves 8 are provided on the inner wall of the outer housing 1. The lower part of the two first grooves 8 is closed, and the upper part is open. The cross-section of the first groove 8 is "convex" shaped, and the two first grooves 8 are symmetrically distributed along the vertical central axis of the outer housing 1. The outer end of the shaft 3 is fitted into the first groove 8. The shaft 3 can slide along the length direction of the first groove 8 and can rotate within the first groove 8, but the shaft 3 cannot detach from the first groove 8. Only when the shaft 3 slides along the length direction of the first groove 8 to the open end at the top of the first groove 8 can the shaft 3 detach from the first groove 8, that is, the inner housing separates from the outer housing 1.

[0031] See Figure 1 , Figure 2 and Figure 3 As shown, in order to control the rotation of the inner shell, a rocking handle 9 is connected to the upper cover 4. The rocking handle 9 is arc-shaped and its two ends are fixed to the upper cover 4. When the inner shell is located in the tilting tank, the upper end of the rocking handle 9 protrudes from the upper opening of the outer shell. When it is necessary to control the swing of the inner shell, the rocking handle 9 can be manually shaken to control the swing of the inner shell, thereby helping to clean the waste carbon brushes inside the inner shell. In addition, the above-mentioned stirring assembly cleans the waste carbon brushes to a certain extent, which also helps to clean the waste carbon brushes.

[0032] See Figure 1 , Figure 2 and Figure 3 As shown, since the crank handle 9 is located inside the outer housing 1, the crank handle 9 is limited by the operator's arm length when manually cranking it. A hanging plate 10 is slidably connected to the outer housing 1. The hanging plate 10 can slide horizontally on the outer housing 1. A 13 is connected to the hanging plate 10. When in use, push the hanging plate 10 to move it horizontally, and the hanging plate 10 can apply a pushing force to the crank handle 9, causing the inner housing to swing, which helps to clean the waste carbon brush.

[0033] The aforementioned hanging plate 10 has an "n" shaped cross section. The hanging plate 10 includes a vertical plate 101 and a flat plate 102. The flat plate 102 is located between the two vertical plates 101 and is integrally connected to the two vertical plates 101. The hook 13 is connected to the lower surface of the flat plate 102. A slider 11 is provided on the inner side of the vertical plate 101. Two sliding grooves are provided at the opening of the aforementioned outer housing. The slider 11 is adapted to the sliding groove and can slide along the length direction of the sliding groove.

[0034] To facilitate the movement of the hanging plate 10, a propulsion assembly can be provided at the opening on the outer shell 1. The propulsion assembly includes a vertical baffle, on which a horizontal electric push rod is connected. The extension and retraction direction of the electric push rod is parallel to the movement direction of the hanging plate. The free end of the electric push rod is connected to the vertical plate 101. Preferably, two sets of propulsion assemblies can be provided. The two sets of propulsion assemblies are symmetrically distributed at the upper opening of the outer shell 1. The free ends of the two electric push rods are connected to the vertical plates 101 on the corresponding sides. When the electric push rods extend and retract, the hanging plate 10 moves along the length direction of the groove.

[0035] The aforementioned stirring assembly includes a protective cover 15 fixed inside the upper cover 4. The protective cover 15 is a conical cover, and the opening of the protective cover is connected to the inner wall of the upper cover 4. A drive motor 16 is installed inside the protective cover 15. The output shaft of the drive motor passes through the protective cover 15 and is connected to a stirring shaft 17. A stirring claw 18 is installed on the stirring shaft 17. The stirring claw 18 is evenly distributed in the lower half of the stirring shaft 17. The stirring shaft 17 has a certain stirring effect on the waste carbon brushes inside the inner shell, and at the same time, it has a certain crushing effect on the waste carbon brushes.

[0036] See Figure 6 and Figure 4 As shown, a partition plate 19 is provided inside the upper cover 4. The partition plate 19 is horizontally positioned and has holes. The space enclosed by the partition plate 19 and the upper cover 4 is the upper space, and the space enclosed by the partition plate 19 and the lower cover 5 is the lower space. The aforementioned stirring claw 18 is located in the lower space, the drive motor 16 is located in the upper space, and the stirring shaft 17 passes through the center of the partition plate 19. Before the waste carbon brushes are cleaned, the waste carbon brushes are located in the lower space and the waste carbon brushes are of different sizes. After the waste carbon brushes are cleaned and the inner shell is rotated 180°, the upper cover 4 is at a lower position and the lower cover 5 is at a higher position. During the rotation process, because the partition plate 19 has holes, the small-sized waste carbon brushes in the lower cover 5 pass through the holes on the partition plate 19 and fall into the upper cover 4, while the larger-sized waste carbon brushes remain in the lower cover 5.

[0037] See Figure 5 , Figure 6 and Figure 7 As shown, a bottom support cover 20 is connected to the outside of the lower cover 5. The bottom support cover 20 is a hemispherical cover with an upward opening. The bottom support cover 20 is provided with water passage holes 22. Several support arms 21 are provided on the inner wall of the bottom support cover 20. The support arms 21 are in a vertical state. Before the inner shell is rotated 180° (that is, before the waste carbon brushes of different specifications in the inner shell are filtered), the support arms 21 are located in the space enclosed by the lower cover 5 and the bottom support cover 20. The bottom support cover can wrap the waste carbon brushes that fall from the lower space and prevent them from falling into the outer shell 1.

[0038] After the inner shell is rotated 180°, the support arm 21 on the inner wall of the bottom cover 20 can pass through the hole on the lower cover 5 and be inserted into the lower cover 5 under the action of gravity. At this time, with the cooperation of the stirring component and the support arm 21, the crushing effect of the larger waste carbon brushes in the lower cover 5 is better, thus facilitating subsequent recycling.

[0039] In order to fix the flipped content shell, a lifting ring 23 is set at the center of the outer bottom of the lower cover 5. The lifting ring 23 has a "U" shaped cross section. The lifting ring 23 passes through the bottom support cover 20. The open end of the lifting ring 23 passes through the bottom support cover and connects to the lower cover. After the content shell is flipped 180°, the lifting ring 23 is hung on the hook 13 to fix the content shell.

[0040] The connection structure between the bottom cover 20 and the lower cover 5 is as follows: An extension plate 2001 is connected to the upper opening of the bottom cover 20. Before the inner shell is rotated 180°, the extension plate 2001 and the lower cover 5 are indirectly connected through the connecting plate 6, since the connecting plate 6 is connected to the lower cover 5. The extension plate 2001 is located on the side of the shaft 3. A second groove is provided on the inner side of the extension plate 2001. The second groove has the same shape as the first groove 8, but both ends of the second groove are closed. A support column with a "T" shaped cross section is connected to the outer side of the connecting plate 6. The support column has a square cross section and is adapted to the second groove. The support column can slide along the length of the second groove but cannot be disengaged from the second groove and cannot be rotated in the second groove. After the inner shell is rotated 180°, the bottom cover 20 slides in the second groove under the action of gravity and slides to a state that is almost in contact with the lower cover 5. At this time, the support arm 21 is inserted into the lower space.

[0041] See Figure 6 , Figure 7 As shown, when using the above-mentioned waste carbon brush recycling device, firstly, the upper cover 4 and the lower cover 5 are separated, then the sorted waste carbon brushes are loaded into the lower cover 5 and the upper cover 4 and the lower cover 5 are connected; then the connected inner shell containing the waste carbon brushes is installed onto the outer shell 1 of the corresponding cleaning tank (the shaft 3 is slid down from the top of the first groove 8 on the corresponding side along its length to the bottom of the first groove 8), then the drive motor 16 is turned on, the stirring claw 18 starts to rotate, and the hanging plate moves, causing the inner shell to swing left and right, and the waste carbon brushes in the lower cover 5 move accordingly and are cleaned to a certain extent;

[0042] After cleaning the waste carbon brushes inside the inner casing to a certain extent, the inner casing is flipped 180° and suspended on the lifting rod using the lifting ring 23 and hook. At this time, the lower cover 5 is at a higher position and the upper cover 4 is at a lower position. During the flipping process, the small-sized waste carbon brushes in the lower cover 5 pass through the holes on the separator plate 19 and fall into the upper cover 4, while the larger-sized waste carbon brushes remain in the lower cover 5. At this time, the bottom support cover 20 slides downward in the second groove under the influence of gravity. The free end of the support arm 21 connected to the bottom support cover 20 passes through the mesh on the lower cover 5 and is inserted into the lower cover 5. With the cooperation of the stirring claw 18 and the support arm 21, the large-sized carbon brushes are further crushed, thus facilitating recycling.

[0043] See Figure 8 As shown, in another embodiment of the present invention, in order to clean the waste carbon brushes more thoroughly, there can be multiple outer shells, preferably three. The three outer shells are arranged in sequence, but the cleaning liquids they contain are different. The three outer shells 1 are connected to each other by a horizontal tie rod. A lifting beam 14 is connected above the three outer shells. The shape of the lifting beam 14 is the same as that of the hanging plate 10, but the horizontal height of the lifting beam 14 is greater than that of the hanging plate 10. A lifting mechanism is connected to the lifting beam 14. The lifting mechanism includes a sleeve 24 sleeved on the lifting beam 14. The sleeve 24 can slide along the length of the lifting beam 14. A vertical electric push rod 12 is connected to the lower surface of the sleeve 24. A hook 13 is connected to the free end of the electric push rod 12. The inner shell can be hung on the hook. When the electric push rod 12 extends or retracts, it can move the inner shell in the vertical direction and push the sleeve 24, so that the inner shell can slide from the top of one cleaning tank to the top of another cleaning tank.

[0044] During use, the inner casing containing the waste carbon brushes is cleaned sequentially using the lifting structure. Finally, the inner casing is rotated 180° and then hung on the lifting beam 14 using the lifting ring 23. The larger waste carbon brushes filtered out are further crushed to facilitate subsequent recycling.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be primarily defined by the scope of the claims.
