NOVELTY - The utility model claims a preparation tank of graphene three-dimensional hierarchical porous material, relating to the technical field of preparation tank, comprising a tank body; the output end of the top part of the tank body is fixedly installed with a screening device; the outer surface of the tank body is fixedly installed with a connecting mechanism; the bottom of the connecting mechanism is fixedly installed with a driving mechanism; the screening device comprises a feeding shell; the upper side of the feeding shell is rotated with a turntable. The utility model, when the ground is not flat, opening the switch; the motor electric threaded rod rotates in the bearing; the limiting block limits the threaded hole block in the limiting groove; the threaded hole block drives the moving frame to move; the moving frame drives the supporting frame to move through the inclined rod; the fixing ring drives one side of the tank body to move; the fixed ring electric connecting frame is rotated on the force rod; the tank body is adjusted to the level; when the ground is inclined, the level of the preparation tank can be adjusted, making the preparation tank exert the best working state.
