An object carrier frame 4 is arranged in the furnace 3; the object carrier frame 4 is used for placing aluminum ingots to be melted and simultaneously separates impurities in the liquid after melting, so as to ensure the purity of the aluminum liquid.

[0024] A shaking structure for driving the furnace 3 to shake vertically is arranged on the vertical plate 2, and a moving structure for driving the object carrier frame 4 to move vertically is arranged on the furnace 3.

[0025] A pair of heat insulation doors 9 is movably connected to the top of the furnace 3 by hinges, the heat insulation doors 9 not only have heat insulation effect, but also can effectively prevent heat loss. Handles are fixedly connected to the top of the heat insulation doors 9, and through openings 10 are formed in the heat insulation doors 9.
