The heat-accumulating burner arranged in pairs generally used now, reach the effect of significantly economize energy, but for 24 hours quantity-produced smelting furnaces, burner position, furnace wall local temperature is too high, burner hearth inside also forms localized hyperthermia close to burner position simultaneously, smelting furnace is shortened service life greatly, and part aluminium liquid scaling loss is serious, increases maintenance cost and drops into.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of aluminium melting furnace, and it has burner hearth combustion homogeneous temperature, long service life, energy-conserving and environment-protective, smelting quality high.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of aluminium melting furnace, comprise smelting furnace burner hearth, smelting furnace burner hearth front is provided with fire door, for carrying out proportioning to air and combustion gas, and the flammable mist formed after proportioning is sprayed into by fire door the burner that burner hearth carries out burning, the waste gas that flammable mist produces after burner hearth combustion enters smoke discharging pipe, and suck smoke stack emission by air-introduced machine, furnace flame harmonious combustion energy saver is provided with: be respectively equipped with auxiliary air-waste gas at the left side wall of smelting furnace burner hearth and right side wall and import and export between smoke discharging pipe and burner hearth, two auxiliary air-waste gas are imported and exported and are communicated with regenerator respectively, regenerator comprises closed shell, heat storage is provided with in closed shell, two regenerator three-way switch valve of respectively hanging oneself is communicated with secondary blower or smoke discharging pipe selectively.
The present invention improves further and is:
Furnace flame harmonious combustion energy saver is bilateral symmetry, the rear that the connected entrance be communicated with is positioned at regenerator is imported and exported with auxiliary air-waste gas, the connected entrance be communicated with three-way switch valve is positioned at the front of regenerator, and furnace flame harmonious combustion energy saver is bilateral symmetry.
The secondary blower be communicated with two three-way switch valves shares one.
Regenerator volume is 1/2 of smelting furnace combustion space.
The heat storage material be provided with in the closed shell of regenerator is honeycomb ceramic heat accumulator.
The beneficial effect adopting technique scheme to produce is:
The present invention is by regulating burner, the flammable mist imperfect combustion in burner hearth formed after making air and gas proportioning, combustion gas is superfluous, combustion gas and fraction normal temperature air are supplied by burner, the normal temperature air of fraction is mainly used in lighting of combustion gas, and unlit most combustion gas is dispersed evenly in burner hearth; Burning auxiliary air enters in stove by post-blast machine by regenerator by furnace flame harmonious combustion energy saver, heat storage in regenerator carries out preheating to auxiliary air, to reach energy-conservation object, the superfluous combustion gas that auxiliary air and burner spray is met and is burnt, combustion flame is banded around form, be looped around in whole burner hearth, solve the problem of the localized hyperthermia of different situations in aluminium melting furnace burner hearth in the past.Make each spot temperature in burner hearth even, thus extend the service life of aluminium melting furnace, effectively control the scaling loss of aluminum alloy melt.Furnace flame harmonious combustion energy saver is bilateral symmetry, the rear that the connected entrance be communicated with is positioned at regenerator is imported and exported with auxiliary air-waste gas, the connected entrance be communicated with three-way switch valve is positioned at the front of regenerator, and furnace flame harmonious combustion energy saver is bilateral symmetry.Rationally distributed, effectively can save and take up an area space, save construction cost, shorten pipeline distance, thus play energy-conservation object.The present invention has burner hearth combustion homogeneous temperature, long service life, energy-conserving and environment-protective, smelting quality high.
