Therefore, a porous carbon composite material preparation device is proposed. Utility Model Content

[0021] This utility model has the following beneficial effects:

[0022] 1. Compared with the prior art, this porous carbon composite material preparation device, by setting up a rotating rod, baffles, gears, a first rotating shaft and a first servo motor, etc., the first servo motor drives the first rotating shaft to rotate, the first rotating shaft drives two meshing gears to rotate, and the gears drive the corresponding baffles to rotate through the rotating rod. The distance between one end of the two baffles can be adjusted according to the needs, so that the nitrogen source is fed into the mixing tank at a uniform speed and mixed evenly with the carbon source, reducing the risk of local accumulation of nitrogen source and improving the mixing effect.

The actuating column 903 actuates one end of the actuating rod 905, causing the other end of the actuating rod 905 to drive the impact column 906 to tilt up and stretch the spring 907. When the actuating column 903 disengages from the actuating rod 905, under the elasticity of the spring 907, the actuating rod 905 drives the impact column 906 to strike one side of the storage box 7, generating vibration. This prevents the nitrogen source powder from forming an "arch bridge" phenomenon at the outlet, which helps to ensure smooth material feeding.
