[0021] Working principle: When using the permanent magnet drum magnetic separator with a dust-proof structure, first, the controller controls the motor and the air pump 5 to be powered on and work. The motor drives the magnetic separation drum 11 to rotate clockwise inside the housing 1. At the same time, the air pump 5 works to extract the gas and dust inside the housing 1 through the input pipe 3, and then transports them through the output pipe 4 to the inside of the dust collection filter bag 6 for dust filtration and collection. The filtered gas enters the inside of the filter box 7, and then is transported to the inside of the protection box 12 through the connecting pipe 8, and the gas is discharged from the shaft hole, thereby preventing the outside dust from entering the inside of the protection box 12.
