Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1-2, the present utility model provides a technical solution: a dust removal device for recycling waste lithium batteries, which includes an outer box body 1 and an inner box body 2. The inner box body 2 is located inside the outer box body 1, and a number of through holes 3 are provided on each of the four side surfaces of the inner box body 2. A lifting motor 4 is fixedly installed on the back of the outer box body 1 through a bracket. A lifting beam plate 5 is installed on the top of the inner box body 2, and the left and right ends of the lifting beam plate 5 are fixed to the top of the left and right ends of the inner box body 2. The bottom end of the lifting shaft of the lifting motor 4 is fixedly connected to the center of the lifting beam plate 5;

[0020] Wherein, a telescopic motor support plate 6 is fixedly installed on the outer side of one end of the inner box body 2, and a part of the telescopic motor support plate 6 is located outside the outer box body 1. A telescopic motor 7 is fixedly installed on the telescopic motor support plate 6. The telescopic motor 7 is connected to an electric push rod 9 through a telescopic shaft 8. The top end of the electric push rod 9 is installed with a slider 10. A chute along the length of the lifting beam plate 5 is provided on the bottom surface of the lifting beam plate 5. The bottom end of the electric push rod 9 is connected to a pressing plate 11, and a first cleaning brush 12 is provided on the bottom surface of the pressing plate 11;

[0021] A number of equally spaced rotating drums 13 are rotatably installed on the bottom surface of the inner box body 2. A second cleaning brush 14 is provided between two adjacent rotating drums 13. The rotating drum 13 is a hollow cylinder, and a number of through holes 3 are provided on the outer surface of the rotating drum 13.

[0022] A lithium battery cleaning liquid is poured into the inside of the outer box body 1. A drain port 15 is provided on the outer side of the outer box body 1. After the lithium battery cleaning liquid is poured into the outer box body 1, it penetrates through the through holes 3 and enters the inside of the inner box body 2 to clean the lithium batteries.

[0023] The lifting motor 4 drives the lifting beam plate 5 through the lifting shaft to pull the inner box body 2 and the telescopic motor support plate 6 to float up and down inside the outer box body 1. The inner box body 2 is pulled by the lifting beam plate 5 under the action of the lifting shaft of the lifting motor 4 to float up and down inside the outer box body 1. A telescopic motor support plate 6 is fixed to the side of the inner box body 2, and one end of the telescopic motor support plate 6 extends to the outside of the outer box body 1. When the inner box body 2 moves downward, the telescopic motor support plate 6 moves up and down accordingly. When the telescopic motor support plate 6 abuts against the edge of the outer box body 1, the inner box body 2 moves downward to the maximum range. Then, the inner box body 2 is pulled by the lifting motor 4 to move upward inside the outer box body 1 to prevent the telescopic motor support plate 6 from being damaged when it is abutted against during the downward movement.

[0024] The telescopic motor 7 drives the electric push rod 9 to move horizontally inside the inner box 2 through the telescopic shaft 8. The top end of the electric push rod 9 is slidably connected to the bottom surface of the lifting beam 5 through the slider 10. The end of the telescopic shaft 8 of the telescopic motor 7 is fixed to the electric push rod 9, and the electric push rod 9 is controlled to perform a stretching movement inside the inner box 2, thereby driving the pressure plate 11 to move back and forth on the upper surface of the lithium battery, thereby washing away the dust on the upper surface of the lithium battery.

[0025] The electric push rod 9 drives the pressing plate 11 to move up and down in the inner box body 2, so as to clean, scrub and remove dust from lithium batteries at different heights.

[0026] Working principle:

[0027] In this scheme, no cleaning and dust removal treatment is performed on block-shaped lithium batteries. In this scheme, when cleaning and dusting the lithium batteries, the lithium batteries are placed inside the inner box body 2, and the lithium battery cleaning liquid is poured into the outer box body 1. Part of the cleaning liquid will penetrate into the inner box body 2 through the through holes on the wall of the inner box body 2. The lifting motor 4 is connected to an external power supply and works. The lifting beam plate 5 is pulled by the lifting shaft to drive the inner box body 2 and the telescopic motor support plate 6 to move up and down as a whole. During the downward displacement of the inner box body 2, when the bottom surface of the telescopic motor support plate 6 is against the edge of the outer box body 1, it is the maximum range of downward displacement. During the up and down floating of the inner box body 2 inside the outer box body 1, the cleaning liquid floats correspondingly inside the inner box body 2;

[0028] After the lithium battery is placed in the inner box 2, the bottom surface of the lithium battery and the plurality of rotating rollers 13 are in rolling friction contact, and the lithium battery cleaning liquid in the outer box 1 also penetrates into the inner box 2 from the through holes of the rotating rollers 13, and achieves a fluid contact effect with the bottom surface of the lithium battery. The second cleaning brush 14 between the plurality of adjacent rotating rollers 13 cooperates with the cleaning liquid to clean the bottom surface of the lithium battery.

[0029] After the lithium battery is placed in the inner box body 2, the electric push rod 9 works to move the pressing plate 11 downward until the first cleaning brush 12 on the bottom surface of the pressing plate 11 contacts the upper surface of the lithium battery, and then the telescopic motor 7 on the telescopic motor support plate 6 works to push the electric push rod 9 horizontally forward and backward inside the inner box body 2. The top end of the electric push rod 9 is slidably connected to the slide groove on the bottom surface of the lifting beam plate 5 through the slider 10, which plays a role in guiding the electric push rod 9 to slide horizontally. When the electric push rod 9 is pushed back and forth by the electric telescopic shaft of the telescopic motor 7, the corresponding first cleaning brush 12 on the bottom surface of the pressing plate 11 washes and dusts back and forth on the upper surface of the lithium battery. When the width of the lithium battery is smaller than the width of the pressing plate 11, a part of the first cleaning brush 12 on the bottom surface of the pressing plate will also wash and dust the side of the lithium battery.

[0030] After the above-mentioned washing is completed, control the electric push rod 9 to pull the pressing plate 11 upward, and then stop the operation of the telescopic motor 7. The lifting motor 4 pulls the lifting beam plate 5 to pull the inner box body 2 upward from the inside of the outer box body 1, and open the drain port 15 on the outside of the outer box body 1 to discharge the cleaning liquid of the lithium battery. Then, clean water can be poured into the outer box body 1 and the inner box body 2 again to wash and clean the box body and the lithium battery. Thus, the dust removal and cleaning of the lithium battery are completed. That is, in the whole device, the cleaning liquid can be in fluid contact with the lithium battery on all sides around the lithium battery. When the inner box body 2 floats up and down inside the outer box body 1, the cleaning liquid seeps into the inner box body 2 through the through holes 3 inside the outer box body 1 and is in a fluid state, playing a certain cleaning effect, and cooperating with the first cleaning brush 12 and the second cleaning brush 14 to further wash and remove dust on the surface of the lithium battery.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
