A graphite crushing and recycling device for lithium batteries is shown in figures 1-5 and comprises a cylinder 11, a bracket 12 arranged at the lower end of the cylinder 11, a screen 13 which is arranged in the cylinder 11 and gradually decreases from the center to the edge in the radial direction of the distance from the inner bottom surface of the cylinder 11, a discharge hole 14 arranged on the inner bottom surface of the cylinder 11, a recycling hole 15 which is arranged on the side surface of the cylinder 11 and corresponds to the edge of the screen 13, a recycling box 21 which is arranged on the side surface of the cylinder 11 and is connected with the recycling hole 15, a collecting box 22 arranged at the lower end of the recycling box 21, and a blowing structure 23 which is arranged in the recycling box 21 and is used for blowing recycled materials into the collecting box 22.

The device for crushing graphite materials, such as a feeding pipe, a fixed motor, a rotating shaft, a crushing blade and the like, is arranged at the upper end of the screen 13 in the cylinder 11, and the above components are structures commonly used by those skilled in the art for crushing graphite materials, and therefore are not described in detail in this embodiment. The screen 13 is located at the lower end of the crushing device and is used for completely receiving and screening the crushed graphite materials.

In this embodiment, the screen 13 is a circular screen attached to the inner wall of the barrel 11, and the circular screen is of a slope-shaped structure with a high center and a low edge, so as to lead the coarse graphite particles remaining on the screen to slide down to the recovery opening 15 under the guidance of an inclined plane, enter the recovery box 21, and finally enter the collection box 22; the blowing structure 23 is arranged at the upper end of the inner wall of the recovery box 21 and used for blowing the graphite coarse particles into the collection box 22, so that the graphite coarse particles are prevented from being accumulated at the recovery port 15, the recovery efficiency is prevented, and the screening effect is even reduced.

In this embodiment, the recycling bin 21 includes a side plate 211 disposed on the outer circumferential surface of the cylindrical body 11, a bottom plate 212 disposed at the lower end of the side plate 211 and connected to the sidewall of the cylindrical body 11, an opening 213 disposed on the bottom plate 212, and a first bracket 214 disposed at an end of the side plate 211 away from the cylindrical body 11. The bottom plate 212 is a ring plate sleeved on the outer side of the cylinder 11 and has an inclination, the inclination direction is consistent with that of the screen 13 on the same side, and the highest position of the bottom plate 212 is lower than the lowest position of the screen 13, so that graphite materials can enter the recovery tank 21 quickly; the higher side of the bottom plate 212 can be directly and fixedly connected with the side wall of the cylinder 11, and the connection mode can be welding; the side plate 211 is installed at the lower side of the bottom plate 212 and can be fixedly connected with the bottom plate 212 by welding or integrally forming, which has the advantages that: firstly, the graphite coarse material can be guided by the inclined surface of the bottom plate 212 to quickly slide to the opening 213 and fall into the collection box 23 through the opening 213, so that the recovery efficiency is improved; secondly, the structure does not occupy the internal volume of the cylinder 11, does not influence the crushing and screening efficiency, and can quickly observe the situation of collecting the graphite coarse grains so as to judge the recovery state; thirdly, the structure has a dustproof effect and does not affect the health of workers.

In this embodiment, the collecting box 22 includes an annular box body 221 having an upper opening and connected to a lower end of the side plate 211, a second bracket 222 provided at a lower end of the annular box body 221, a fixing hole 223 provided at a side of the annular box body 221 adjacent to the bracket 12, a mounting screw hole 224 provided at the bracket 12 and corresponding to the fixing hole 223, a plug plate 225 provided at the annular box body 221, a plug groove 226 provided at a lower surface of the side plate 211 and adapted to the plug plate 225, and a countersunk groove 227 provided at the mounting screw hole 224 at the bracket 12.
