The invention provides a closed energy collected nonferrous metal smelting furnace with multi-functions, which relates to the refining and the smelting technical field of the metallic substance; the nonferrous metal smelting furnace is characterized in that combustion walls enclose under the top part of the smelting furnace, and is communicated with a recovery tank, a warm-air pipe connected withthe multi-holes melting zone at the bottom of the furnace is joined with an air inlet pipe, hot blast gallbladders are around the entourage in the centre of the furnace, a pair of temperature increasing electrodes are inserted in the centre opposite the two sides of the furnace bottom, and holes are arranged at the bottom side of the recovery tank; the recovery tank is connected with the bottom ofa washing pool through a pipe, and the clean coal gas is guided out from an outlet on the top to be reclaimed; a heavy metal tapping hole is arranged at the bottom of the smelting furnace. After theinvention is brought to effect, heat energy radiation is reduced; the smelting is uniform and sufficient, without salamander; the utilization of waste gas heat is increased in the furnace, and energyconsumption is reduced; the metal smelting speed can be increased by the temperature increasing electrode; the low boiling point metal recovery tank ensures that the smelting efficiency is better; thepower expenditure occupies one twenty seconds of the normal consumption; the speed of aluminum production is improved greatly, and the problems that the conventional refining is not thorough, the metal contained cinder is threw and abandoned all over the hill, the resource is wasted, and the environment is polluted can be solved.
