Battery recycling can prevent environmental pollution and reuse the useful components in them. It has become a subsidiary industry. When graphite and aluminum foil materials are crushed, in order to reduce graphite dust and improve the working environment, it is usually necessary to set up a dust recovery device, using a fan to carry graphite dust through a multi-stage filter, and graphite particles of different particle sizes fall into different collection boxes. However, traditional recycling devices have the problem of graphite particles getting stuck in the mesh of the filter. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is a description of the embodiments of the present invention based on its overall structure.

[0017] Reference Figure 1 and Figure 2 The utility model discloses a graphite dust recovery device, including a dust collecting box 10, the dust collecting box 10 is in a long strip shape, the first and second ends of the dust collecting box 10 are respectively provided with an air inlet 11 and an air outlet 12, and the bottom of the dust collecting box 10 is provided with at least one ash outlet 13. The device also includes a number of filter screens 20 equal to the ash outlet 13, the filter screens 20 are located above the ash outlet 13, and the edges of the filter screens 20 are connected to the inner wall of the dust collecting box 10. The device also includes a motor 31, two rotating shafts 32, two transmission belts 33 and a cross plate 34. The two rotating shafts 32 are arranged in parallel and are respectively located on the upper and lower sides of the dust collecting box 10. The two rotating shafts 32 are hinged to the sides of the dust collecting box 10 so that the rotating shafts 32 can rotate. One transmission belt 33 is wrapped around the head ends of the two rotating shafts 32, and the other transmission belt 33 is wrapped around the tail ends of the two rotating shafts 32. The cross plate 34 is arranged between the two transmission belts 33. The cross plate 34 is parallel to the rotating shafts 32. A flexible brush 35 is arranged on the surface of the cross plate 34. The motor 31 is connected to the end of one of the rotating shafts 32.

[0018] When the motor 31 rotates, it drives the two rotating shafts 32 to rotate and the transmission belt 33 to move. The horizontal plate 34 moves with the transmission belt 33, so that the brush 35 moves on the surface of the filter 20. Preferably, the brush 35 moves on the front of the filter 20, and moves from top to bottom on the side close to the filter 20 to push the graphite dust downward. The filter 20 can intercept most of the graphite dust, reduce air pollution and recycle some raw materials. After the device is used for a long time, the horizontal plate 34 drives the brush 35 to move on the surface of the filter 20, sweeping off the graphite dust embedded in the mesh, and restoring the filtering effect of the filter 20. When the device is self-cleaning, since the rotating shaft 32 only spins, the small-volume horizontal plate 34 only moves up and down, the corresponding moving parts have a small movement amplitude, the noise and equipment vibration generated are small, and the self-cleaning process is smooth; in actual use, the motor 31 only needs to be started at intervals, and the horizontal plate 34 does not need to work continuously.

[0019] As an improvement of the above solution, the transverse plate 34 is made of rubber material, and at least two connection points are set between the transverse plate 34 and the transmission belt 33 so that it can be deformed and move in accordance with the circular arc bend of the rotating shaft 32 .

[0020] As an improvement of the above solution, the cross plate 34 is made of hard plastic, and only one connection point is set between the cross plate 34 and the transmission belt 33. Since the cross plate 34 cannot be bent and deformed, when the cross plate 34 passes through the arc corner of the rotating shaft 32, the front and rear edges of the cross plate 34 temporarily move away from the transmission belt 33. After the transmission belt 33 enters the horizontal section, the bottom surface of the cross plate 34 re-attaches to the transmission belt 33.

[0021] As an improvement of the above solution, the middle section of the rotating shaft 32 shrinks toward its own axis, reducing the diameter of the middle section and reducing the area of ​​gas blocking. The rotating shaft 32 has a larger diameter at the position where it connects to the transmission belt 33, so that the movement of the transmission belt 33 and its transverse plate 34 is more stable.

[0022] As an improvement of the above solution, the transmission belt 33 is a synchronous belt or chain, and accordingly, gears or sprockets are respectively provided at the head and tail ends of the rotating shaft 32. By taking advantage of the consistency of the synchronous belt and sprocket when moving, the transmission belts 33 on the left and right sides are ensured to move the same distance, thereby preventing the cross plate 34 from tilting.

[0023] As an improvement of the above solution, two groups of filter screens 20 are arranged in the dust collecting box 10. The two groups of filter screens 20 have different mesh sizes and are used to filter graphite dust of different particle sizes respectively.

[0024] As an improvement to the above solution, the ash discharge port 13 is configured to be funnel-shaped. Figure 2The bottom of the filter screen 20 cannot be connected to the ash discharge port 13. The filter screen 20 is arranged vertically to facilitate the direct falling of graphite dust.
