The invention relates to an air exhaust feeding box. The air exhaust feed box comprises a material box, a buffer board, screen meshes, a impurity-removing door and a discharging pipe; the buffer boardis arranged in the middle of the material box obliquely, and the buffer board is located below a material discharging port of a ore pulp pipeline; the screen meshes are horizontally arranged in the middle of the material box, and the screen meshes are connected with the buffer board; the impurity-removing door is arranged, away from the buffer board, on one side of the screen meshes and on the side wall of the material box, the discharging pipe is disposed below the impurity-removing door, and the discharging pipe communicates with the bottom of the material box; and an air exhauster is disposed on the upper end of the material box. Compared with the prior art, the air exhauster can extract air from the material box and prevent the bad smell in the material box from affecting the workingenvironment.
