For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of aluminium melting furnace, comprises smelting furnace burner hearth, and smelting furnace burner hearth front is provided with fire door, for to skyProportioning is carried out in gas and combustion gas, and the flammable mist forming after proportioning is sprayed into burner hearth by fire door carries outThe burner of burning, the waste gas that flammable mist produces after stove chamber inner combustion enters smoke discharging pipe,And suck smoke stack emission by air-introduced machine, between smoke discharging pipe and burner hearth, be provided with furnace flame harmonious combustion jointEnergy device: left side wall and right side wall at smelting furnace burner hearth are respectively equipped with the import and export of auxiliary air-waste gas, twoIndividual auxiliary air-waste gas is imported and exported and is communicated with regenerator respectively, and regenerator comprises closed shell, closedIn housing, be provided with heat storage, two regenerator respectively hang oneself three-way switch valve selectively with secondary blowerOr smoke discharging pipe is communicated with.
The utility model further improves and is:
Furnace flame harmonious combustion energy saver is symmetrical structure, imports and exports and connects with auxiliary air-waste gasLogical connected entrance is positioned at the rear of regenerator, the connected entrance being communicated with three-way switch valve be positioned at regenerator beforeSide, furnace flame harmonious combustion energy saver is symmetrical structure.
The secondary blower being communicated with two three-way switch valves shares one.
Regenerator volume is 1/2 of smelting furnace burner hearth volume.
The heat storage material being provided with in the closed shell of regenerator is honeycomb ceramic heat accumulator.
The beneficial effect that adopts technique scheme to produce is:
The utility model, by regulating burner, makes the flammable gaseous mixture forming after air and gas proportioningBody is imperfect combustion in burner hearth, combustion gas surplus, and combustion gas and fraction normal temperature air are supplied with by burner,The normal temperature air of fraction is mainly used in lighting of combustion gas, and unlit most combustion gas is dispersed evenly toIn burner hearth; Furnace flame harmonious combustion energy saver by burning with auxiliary air by post-blast machine by holdingHot cell enters in stove, and the heat storage in regenerator carries out preheating to auxiliary air, to reach energy-conservation object,The superfluous combustion gas of auxiliary air and the burner ejection burning of meeting, it is banded around form that combustion flame is, and encirclesIn whole burner hearth, solve the problem of the localized hyperthermia of the interior different situations of aluminium melting furnace burner hearth in the past. MakeIn burner hearth, each position temperature is even, thereby extends the service life of aluminium melting furnace, effectively controls aluminum alloy meltScaling loss. Furnace flame harmonious combustion energy saver is symmetrical structure, with the turnover of auxiliary air-waste gasThe connected entrance that mouth is communicated with is positioned at the rear of regenerator, and the connected entrance being communicated with three-way switch valve is positioned at regeneratorFront, furnace flame harmonious combustion energy saver is symmetrical structure. Rationally distributed, can effectively saveAccount for space, ground, save construction cost, shorten pipeline distance, thereby play energy-conservation object. This practicality is newType have stove chamber inner combustion temperature evenly, long service life, energy-conserving and environment-protective, smelting quality high.
