The invention discloses an emulsion removing device. The emulsion removing device comprises a first removing assembly arranged at an inlet of the cold rolling mill and a second removing assembly whichis arranged at an outlet of the cold rolling mill and is the same as the first removing assembly in structure. The first removing assembly comprises a blocking spraying beam arranged on the side, close to a first thickness gauge, of an anti-winding guide plate, the blocking spraying beam communicates with an emulsion pipeline, at least one nozzle is arranged on the blocking spraying beam and faces the side close to rollers, and an acute angle is formed between the spraying direction and the plane where a cold-rolled sheet is located. Emulsion sprayed by the blocking spraying beam forms an emulsion curtain with a certain pressure on the cold-rolled sheet, the pressure has component force for blocking reflux emulsion in the rolling direction of the cold-rolled sheet, the reflux emulsion isprevented from flowing to
