Description

Technical Field

[0001] This utility model belongs to the field of waste lithium battery recycling technology, and in particular relates to a pyrolysis device for recycling waste lithium batteries. Background Technology

[0002] With the advancement of technology and the development of manufacturing, coupled with the promotion of energy conservation and emission reduction, the production and use of lithium batteries have been continuously increasing. As a result, the amount of scrapped lithium batteries is also increasing. In order to reduce the environmental impact of scrapped lithium batteries, it is necessary to recycle them. The recycling of lithium batteries requires pyrolysis treatment.

[0003] In the comparative document of a pyrolysis device for recycling waste lithium batteries proposed in announcement number CN221335974U, it is specifically stated that "it includes: a base; a pyrolysis box is provided on the upper end of the base, a refractory insulation layer is provided on the inner wall of the pyrolysis box, an electric heating wire is provided on the inner wall of the refractory insulation layer, a fixed seat is fixedly connected to the bottom surface inside the pyrolysis box, and a slot is provided on the upper end of the fixed seat."

[0004] The aforementioned comparative documents also have the following defects: 1. When the waste lithium batteries in the comparative documents are pyrolyzed and stirred, they cannot be stirred by lifting and adjusting after sealing, resulting in a relatively limited stirring range; 2. When discharging the material after pyrolysis, the reactor needs to be removed first, which is inconvenient for rapid discharge. Therefore, we propose a pyrolysis device for recycling waste lithium batteries. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a pyrolysis device for recycling waste lithium batteries.

[0006] To achieve the above objectives, this utility model proposes a pyrolysis device for recycling waste lithium batteries, including a fixed frame on which two first drive motors are mounted. The output shafts of the drive motors are fixedly connected to rotating shafts, and cams are fixedly fitted on the outside of the rotating shafts. A pyrolysis cylinder is rotatably connected to one end of the two rotating shafts that are close to each other. A cylinder cover is movably fitted on the top of the pyrolysis cylinder. A positioning component is provided at the bottom of the pyrolysis cylinder for positioning the pyrolysis cylinder. A lifting and stirring component is provided inside the pyrolysis cylinder for stirring the lithium battery fragments inside the pyrolysis cylinder.

[0007] Preferably, the lifting and stirring assembly includes two guide rods fixedly connected to the top of the cylinder cover. A spring fixedly connected to the cylinder cover is sleeved on the outside of the guide rods. A lifting plate is fixedly connected to the top of the spring and is movably sleeved on the outside of the guide rods. A stirring mechanism is fixedly connected to the bottom of the lifting plate. Lifting rods are fixedly connected to both sides of the bottom of the lifting plate, and a pressing plate is fixedly connected to the bottom end of the lifting rod.

[0008] Preferably, the stirring mechanism includes a second drive motor fixedly connected to the bottom of the lifting plate, the output shaft of the second drive motor being fixedly connected to a vertical shaft, a plurality of stirring rods being arranged in an array on the outside of the vertical shaft, a bearing being sleeved on the outside of the vertical shaft, and two fixing rods being fixedly connected between the outer ring of the bearing and the lifting plate.

[0009] Preferably, the positioning component includes a push rod motor fixedly connected to the bottom of the fixed frame, and the output shaft of the push rod motor is fixedly connected to a positioning plate.

[0010] Preferably, the cylinder cover has a lifting hole, and the vertical shaft moves through the lifting hole.

[0011] Preferably, the inner wall of the pyrolysis cylinder is inlaid with a plurality of heating rods in a circumferential array to heat the inside of the pyrolysis cylinder.

[0012] The pyrolysis device for recycling waste lithium batteries proposed in this utility model can bring the following beneficial effects:

[0013] 1. The first drive motor drives the rotating shaft to rotate, and the rotating shaft drives the cam to rotate. In this way, the cam will squeeze the lifting and stirring component, and the lifting and stirring component will lift and stir the inside of the pyrolysis cylinder, which can improve the stirring range.

[0014] 2. The pyrolysis cylinder is positioned by the positioning component. After the positioning is released, the pyrolysis cylinder can be rotated and tilted, thus facilitating rapid material discharge.

[0015] In summary, this solution has a simple structure and a novel design. It not only facilitates the lifting and stirring of waste lithium batteries, increasing the stirring range, but also allows the pyrolysis cylinder to rotate after pyrolysis, thus facilitating rapid discharge.

[0029] like Figures 1-5 As shown in the figure, an embodiment of this utility model proposes a pyrolysis device for recycling waste lithium batteries, including a fixed frame 1. Two first drive motors 2 are installed on the fixed frame 1. The output shafts of the drive motors 2 are fixedly connected to rotating shafts 3. A cam 4 is fixedly sleeved on the outside of the rotating shafts 3. A pyrolysis cylinder 5 is rotatably connected to one end of the two rotating shafts 3 that is close to each other. A cylinder cover 8 is movably sleeved on the top of the pyrolysis cylinder 5. A positioning component is provided at the bottom of the pyrolysis cylinder 5 for positioning the pyrolysis cylinder 5. A lifting and stirring component 9 is provided inside the pyrolysis cylinder 5 for stirring the lithium battery fragments inside the pyrolysis cylinder 5.

[0030] like Figure 5 As shown, the lifting and stirring assembly 9 includes two guide rods 901 fixedly connected to the top of the cylinder cover 8. A spring 902 fixedly connected to the cylinder cover 8 is sleeved on the outside of the guide rods 901. A lifting plate 903 is fixedly connected to the top of the spring 902, and the lifting plate 903 is movably sleeved on the outside of the guide rods 901. A stirring mechanism is fixedly connected to the bottom of the lifting plate 903. Lifting rods 909 are fixedly connected to both sides of the bottom of the lifting plate 903. A pressing plate 910 is fixedly connected to the bottom end of the lifting rod 909. The first drive motor 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the cam 4 to rotate. The cam 4 will press the pressing plate 910 upward. In this way, the pressing plate 910 will drive the lifting plate 903 to move upward through the lifting rod 909, while the spring 902 will pull the lifting plate 903 to move downward and reset. In this way, the lifting plate 903 will drive the stirring mechanism to lift and lower.

[0031] like Figure 5As shown, the stirring mechanism includes a second drive motor 904 fixedly connected to the bottom of the lifting plate 903. The output shaft of the second drive motor 904 is fixedly connected to a vertical shaft 905. Multiple stirring rods 906 are arranged in an array on the outside of the vertical shaft 905. A bearing 907 is sleeved on the outside of the vertical shaft 905. Two fixed rods 908 are fixedly connected between the outer ring of the bearing 907 and the lifting plate 903. The second drive motor 904 drives the vertical shaft 905 to rotate, and the vertical shaft 905 drives the stirring rods 906 to rotate and stir. The bearing 907 and the fixed rods 908 reduce the force on the second drive motor 904.

[0032] like Figure 1 As shown, the positioning component includes a push rod motor 6 fixedly connected to the bottom of the fixed frame 1. The output shaft of the push rod motor 6 is fixedly connected to a positioning plate 7. The push rod motor 6 drives the positioning plate 7 to move upward to squeeze and position the pyrolysis cylinder 5.

[0033] like Figure 4 As shown, the cylinder cover 8 has a lifting hole, and the vertical shaft 905 moves through the lifting hole and moves up and down within the lifting hole.

[0034] like Figure 3 As shown, multiple heating rods are embedded in the inner wall of the pyrolysis cylinder 5 in a circumferential array, and the heating rods heat the inside of the pyrolysis cylinder 5.

[0035] Working principle: When waste lithium battery fragments are pyrolyzed in the pyrolysis cylinder 5, the cylinder is heated by a heating rod. The second drive motor 904 drives the vertical shaft 905 to rotate, which in turn drives the stirring rod 906 to rotate and stir. The bearing 907 and the fixing rod 908 reduce the force on the second drive motor 904. At the same time, the first drive motor 2 drives the rotating shaft 3 to rotate, which in turn drives the cam 4 to rotate. The cam 4 presses the extrusion plate 910 upward, which in turn causes the lifting plate 903 to move upward via the lifting rod 909. The spring 902 pulls the lifting plate 903 downward to reset it. The lifting plate 903 then drives the stirring rod 906 to move up and down to stir. When the pyrolysis is completed and the material is discharged, the cylinder cover 8 and the lifting and stirring assembly 9 are first removed from the pyrolysis cylinder 5. The push rod motor 6 drives the positioning plate 7 to move downward to release the compression and positioning of the pyrolysis cylinder 5. At this time, the pyrolysis cylinder 5 can be manually pushed to rotate and tilt, thus facilitating rapid material discharge.

Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0037] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
