Cooling device for graphite powder

The utility model discloses a graphite powder cooling device, which belongs to the technical field of cooling devices and comprises a shell, a feeding pipe is mounted at the top of the shell, the top end of the feeding pipe is communicated with a feeding hopper, and an inner cavity of the shell is rotatably connected with a cooling cylinder. Supporting mechanisms for supporting the cooling cylinder to improve the rotating stability of the cooling cylinder are arranged at the top and the bottom of the cooling cylinder; through the arrangement of the feeding pipe, the feeding funnel, the cooling cylinder, the cooling mechanism and the rotating mechanism, during use, graphite powder needing to be cooled is fed through the feeding funnel, when the graphite powder passes through the cooling mechanism, the cooling mechanism can rapidly cool the graphite powder, and meanwhile the cooling cylinder can be rotated through the rotating mechanism; and cooling water in the cooling cylinder flows, so that the heat exchange
