Embodiment Construction

[0038] like figure 1 , figure 2 and image 3 As shown, it is a regenerative gas-fired crucible furnace, including a frame 1, which is the basic component of the whole device, and other mechanisms are directly or indirectly arranged on the frame 1.

[0039] A furnace shell 3 is fixed on the frame 1, and a crucible body 2 is arranged inside the furnace shell 3. The crucible body 2 is the core component of the regenerative gas-fired crucible furnace in this embodiment, and its main function is to melt and keep aluminum alloy.

[0040] There is a thermal insulation layer 4 between the furnace shell 3 and the crucible body 2, its function is to reduce the heat dissipation of the crucible body 2, improve the thermal insulation performance of the crucible body 2, and then effectively save the consumption of gas and improve the use of gas efficiency.

[0041] The furnace shell 3 is provided with a first burner hole and a second burner hole, wherein the first burner hole is connect...

Abstract

The invention discloses a heat accumulating type gas crucible furnace comprising a rack, a furnace shell, a crucible body, a heat preservation and insulation layer, a first burner hole, a second burner hole, a first heat accumulating type burner, a second heat accumulating type burner, a first reversing valve, a gas inlet pipe connector, a smoke exhaust pipe connector, a second reversing valve, asmoke exhaust pipe, a draught fan, a gas inlet pipe, two smoke adjusting valves and two air adjusting valves. The heat accumulating type gas crucible furnace has the beneficial effects that (1) the structure is simple; and (2) heat in high-temperature smoke gas is alternately absorbed through the first heat accumulating type burner and the second heat accumulating type burner, then air in the gasinlet pipe is heated through the heat so that the consumption of gas can be further reduced when the air is assisted in heating the gas, and the combustion efficiency of the gas can be improved; and meanwhile, the temperature during smoke gas emission can be reduced, the emitted heat is reduced, and the environment is effectively protected.

Description

technical field [0001] The invention relates to a crucible furnace, in particular to a gas-fired crucible furnace. Background technique [0002] At present, the existing gas-fired crucible furnace is mainly used for melting and heat preservation of aluminum alloy. It uses a common burner or a burner, and the fan supplies air to support the combustion. The flame burns in the furnace, and the smoke after combustion is directly discharged from the chimney. The temperature of the flue gas after combustion can reach more than 1000°C, and it is directly emptied, which not only affects the working environment, but also causes a waste of energy. [0003] This patent describes a regenerative crucible furnace, the crucible furnace uses two regenerative burners, each regenerative burner has a regenerator box filled with a regenerator, and the regenerative body absorbs The heat of the high-temperature flue gas can reduce the exhaust gas temperature to below 200°C, and the combustion-su...
