10. The method of using a metal refining low density dross removal apparatus of claim 9, comprising the steps of:
s1: the metal is heated and melted at the bottom of the heating and melting cylinder (1), scum is suspended on the surface of molten metal, a hydraulic lifting hanger rod (51) lowers a separating disc (56) to be in semi-submerged contact with the molten metal, a rotating rod (55) drives the separating disc (56) to rotate, and the separating disc (56) shifts and collects the scum suspended at the center of the molten metal to the peripheral edges through the rotation of a shifting strip (512) at the bottom;
s2: when the separating disc (56) rotates, the catching part (58) is driven to catch the collected scum mixed metal liquid together and convey the scum mixed metal liquid to the inner cavity of the separating disc (56), then the separating disc (56) is moved up and down by the hydraulic lifting hanger rod (51), and the metal liquid is filtered and leaked through the catching part (58) and a filtrate hole (510) on the bottom plate of the separating disc (56) during conveying;
s3: the adsorption air extractor (8) is started, the air extraction pipe (9) is communicated with the scum suction pipe (57) to suck scum on the bottom plate of the separation disc (56), and the scum separated by the scum suction pipe (57) is transferred to the outside of the heating melting cylinder (1) to be processed;
s4: when the scum on the bottom plate of the separating disc (56) is sucked by the scum suction pipe (57), the steam generator (10) is started, steam is conveyed to the steam conveying pipe (11) by the steam conveying pipe (11) to jet air to the separating disc (56), and molten metal collected on the bottom plate of the separating disc (56) is blown by the steam to flow, so that the scum is prevented from blocking filtrate holes (510);
s5: when small-particle scum suspended in the molten metal is collected in the separation disc (56) and the auxiliary dust collecting disc (59) at the top of the catching part (58), part of the small-particle scum is sucked and removed together with the scum through a bottom port of the scum suction pipe (57), part of the small-particle scum is heated and dried after the molten metal is separated, and the small-particle scum is blown by steam airflow to be lifted and collected at the gas collecting hood (52) and then enters the scum suction pipe (57) to be transferred.
