The present invention discloses a metal powder production dust removal equipment with the collecting and screening functions. The equipment comprises a metal powder processing box, a dust removal screening box is arranged on one side of the metal powder processing box, and a purification box is arranged on the side, away from the metal powder processing box, of the dust removal screening box; wherein the outer wall of one side of the metal powder machining box is fixedly connected with a first connecting pipe, and the outer wall of one side of the dust removal screening box is fixedly connected with a draught fan. During use, the first motor is started to drive a first gear to rotate so as to drive a second gear to rotate, then the rotation of the second gear drives stirring blades and gathering blades to rotate, and the rotation of a first rotating shaft, the stirring blades and the gathering blades generates centrifugal force in a bearing cylinder, so that metal powder dust is gathered towards the middle. According to the equipment, through combined arrangement of the stirring blades, the receiving cylinder and other devices, dust entering the receiving cylinder is gathered and made to move downwards, dust flying is avoided, and the dust is not likely to be collected.
