Waste lead-acid storage battery smelting device and method

The invention discloses a waste lead-acid storage battery smelting device and method. The waste lead-acid storage battery smelting device comprises a smelting device body and a first spiral feeder, wherein the first spiral feeder is installed in the lower end of the smelting device body, and a material channel is formed on the lower side of the first spiral feeder. A molten lead outlet is formed in the outer wall of the right side of the lower end of the smelting device body, and mixed fuel inlets are formed in the outer wall of the front side of the lower end of the smelting device body. A second filter screen is arranged in the inner wall of the lower end of the smelting device body. The first spiral feeder and a second spiral feeder are internally arranged, when the first spiral feederand the second spiral feeder conduct feeding, materials sequentially pass through a fine smelting cavity, a heat preservation cavity and a rough smelting cavity, and then layered smelting of the materials is achieved; and bes
