A metal dust collector according to the present invention comprises: a housing including a suction duct where a collection hose for collecting air containing metal dust, an emission duct where the air in which the metal dust is removed is emitted, and a filter fixating unit; at least one filter unit which is fixated to the filter fixating unit while adsorbing the metal duct which is introduced along with the air through the suction duct; an air blower unit for providing a drive force for emitting the air removed of metal dust to the outside, after the metal dust is adsorbed and removed at the suction duct; a pressurized air spraying unit installed on one side of the housing to blow the metal dust absorbed by the filter unit by spraying pressurized air to the inside of the filter unit; a dust recollection unit installed on the bottom of the housing to collect the metal dust falling from the housing; a magnetizing dust transfer unit prepared on one side of the housing, while forcibly adsorbing the metal dust on a predetermined position on one side of the housing, after using the magnetic force of a permanent magnet member to collect the metal dust which flows in with the air though the suction dust, and recollecting the metal dust by making the permanent magnet member transferred to the bottom by a magnet transfer member; and a control unit for displaying and controlling the operation, cessation, drive management and alarms of each unit.;COPYRIGHT KIPO 2016
