Chinese patent 201020248996.5 discloses a kind of non-ferrous metal melting stove; It comprises the shaft furnace that is provided with bell, the end stove that is provided with fire door, is communicated with the aditus laryngis of shaft furnace and end stove; The furnace wall arranged outside of stove of the said end has the burner of blast pipe; The top of said shaft furnace is provided with heat exchanger, and the top of said heat exchanger is provided with fume extractor: shaft furnace one side is provided with air blast, and air blast links to each other with heat exchanger through the air channel: the internal diameter >=1500mm of said shaft furnace.This technology metal molten speed is fast, and scaling loss is little, has improved the utilization ratio of fume afterheat greatly, burns but flue gas gets into inner counter, has increased metal impurities, and seriously polluted.
The utility model content
According to above deficiency of the prior art, the problem that the utility model will solve is: a kind of using gases fuel is provided, clean environment firendly, sufficient combustion, the non-ferrous metal energy-saving gasification stove that the thermal efficiency is high.
The utility model solves the technical scheme that its technical problem adopted: non-ferrous metal energy-saving gasification stove; Comprise melting furnace; It is characterized in that: melting furnace set inside melting tank; The fiber drawing furnace that melting furnace one side setting is communicated with it, the melting tank bottom of fiber drawing furnace and melting furnace is provided with the liquid metal passage; Described melting furnace is provided with fire door, and the furnace wall of melting furnace is provided with the burner that circles round, and the combustor external that circles round connects gaseous fuel and air mixing tube.
Open fire door, in melting tank, place solid-state non-ferrous metal.Gaseous fuel mixes the back and gets into the burner combustion of circling round with air, the non-ferrous metal in the melting tank is heated.Non-ferrous metal liquefies after temperature reaches 500-1500 °, flows to fiber drawing furnace through the liquid metal passage and carries out wire drawing.Because gaseous fuel direct is connected on the melting furnace internal combustion non-ferrous metal is directly heated, and has reduced circulation heat radiation process, has improved the thermal efficiency.Gaseous fuel can be coal gas, natural gas, methane, acetylene etc., during burning and air mix, do not produce black smoke and impurity, clean environment firendly.
Wherein preferred version is:
Described liquid metal channel bottom is provided with the siege of inclination.Make liquid non-ferrous metal conveniently flow into fiber drawing furnace swimmingly.
The described burner that circles round comprises fuel gas inlet and the bocca that is arranged on the furnace wall, and fuel gas inlet is arranged on cylindrical melting tank top, and is downward-sloping.Light after the bocca, flame sprays earlier downwards heating, returns heating on again, and sufficient combustion improves the efficiency of heating surface.
Described bocca correspondence is arranged on same horizontal plane, and the circumference vertical line of the center line of some boccas and melting tank is 5-30 ° of angle.Be uniformly distributed with after the bocca on the melting tank circumference, when lighting together, flame is the state of circling round in melting tank, and it is more abundant to burn, and improves fuel availability, and is energy-conservation.
Described melting furnace top is provided with the hot gas path that is connected with fiber drawing furnace.Residue hot gas gets into fiber drawing furnace through hot gas path, and the liquid towards non-ferrous metal is incubated.
The beneficial effect that the non-ferrous metal energy-saving gasification stove of the utility model is had is: through the liquid metal passage of inclination is set in the melting tank bottom of fiber drawing furnace and melting furnace; The furnace wall of melting furnace is provided with the burner that circles round, and the combustor external that circles round connects gaseous fuel and air mixing tube, because gaseous fuel direct is connected on the melting furnace internal combustion non-ferrous metal is directly heated, has reduced circulation heat radiation process, has improved the thermal efficiency.During gas fuel combustion and air mix, sufficient combustion does not produce black smoke and impurity, clean environment firendly.The utility model clean environment firendly, sufficient combustion, the thermal efficiency is high, and is energy-conservation.
