The mixed gas copper smelting furnace is composed of a melting chamber 4 and a mixed gas generating chamber 10, wherein, the melting chamber and the mixed gas generating chamber are communicated by a gas passage 6; a secondary wind passage 7 is accessed in the gas passage 6; the mixed gas generating chamber adopts a full close structure closed by water at upper and lower parts. The utility model utilizes the low-temperature burning of lump coal in the mixed gas generating chamber to generate mixed gas; the mixed gas enters the melting chamber via the gas passage 6 to melt and refine copper. The utility model has high thermal efficiency, little pollution, low manufacturing cost; the utility model can enhance the purity of refined copper liquid.
Description
The utility model includes the smelting furnace of non-ferrous metal processing, and especially a kind of bituminous coal combustion that utilizes produces mixed gas, and makes the mixed gas copper smelting furnace of fuel with mixed gas.
In non-ferrous metal processing, the melting copper smelting furnace of production of copper wire bar, sun level copper coin, copper section bar etc. is indispensable major equipment.What extensively adopt in middle-size and small-size source mill at present is the reverberatory furnace of lump coal of burning the fifties, its structure as shown in Figure 2, its principle of work is, lump coal layer 26 burns in combustion chamber 25, the flame that produces is through the reflective layer reflects of top of combustion chamber, by turning in the wall with flues 31 tops arrival melting chamber 22 copper is heated melting, lump coal adds through being positioned at combustion chamber 25 lateral coal filling holes 27.Because it is to utilize the flame of coal combustion directly copper to be heated, thereby its heat utilization efficiency is low, consumption of coal is big, single with the coal kind, labour intensity is big, and environmental pollution is serious, especially when refined matte, there are objectionable impuritiess such as a large amount of coal ash, cinder to enter in the melting chamber, influenced the purity of copper liquid.Also have the direct shock-wave reflection layer of thermal-flame, easily cause the damage of furnace roof.
The purpose of this utility model is to provide a kind of bituminous coal combustion that utilizes to produce mixed gas, and makes the mixed gas copper smelting furnace of fuel with this mixed gas, to solve the defective that above-mentioned prior art exists.
The utility model is made up of a melting chamber 4 and at least one mixed gas generation chamber 10, copper outlet 1 is arranged in melting chamber 4, skimming gate 2, smoking road 3 and advance copper material mouth 5, coal filling hole 8 and fire grate 13 are arranged in mixed gas generation chamber 10, wherein, coal filling hole 8 is positioned at the top of mixed gas generation chamber 10, fire grate 13 is positioned at the bottom of mixed gas generation chamber 10, on coal filling hole 8, sealing cover is arranged, in fire grate 13 times air port 16 once, between melting chamber 4 and mixed gas generation chamber 10, there is gas flue 6 to communicate, in gas flue 6, also have a secondary air duct 7 to communicate with it, the air outlet direction of gas flue 6 is aimed at the central authorities of melting chamber 4, water seal pond 9 on having around the coal filling hole 8 of mixed gas generation chamber 10, manhole cover 32 is being housed on the coal filling hole 8, and the edge of last manhole cover 32 submerges and goes up in the water in water seal pond 9, utilizes water will go up manhole cover 32 and seals up.In the water under the following water seal box 15 that we opens have below the fire grate 13 of mixed gas generation chamber 10 about, the bottom of following water seal box submerge in the water seal pond 14, by water-lute.
In addition, the angle of gas flue 6 and secondary air duct 7 intersections is in the time of 15 ℃-30 ℃, and the ratio of secondary air duct 7 and the sectional area of gas flue 6 is when 1:1.6-1:1.8, and the combustion efficacy of mixed gas is best.
The utility model be by by block bituminous coal the sealing mixed gas generation chamber 10 in low-temperature burning (500-900 ℃), produce mixed gas, mixed gas is delivered to melting chamber 4 internal combustion through gas flue 6, produces the heat supply of thermal-flame air-flow and carry out melting copper or refined matte under the effect of the secondary pressure air that secondary air duct 7 is sent.Cinder in the mixed gas generation chamber 10 is freely to fall into down 14 bottoms, water seal pond by shaking of moving grate 13 to remove.
The mixed gas copper smelting furnace contrasts with reflective copper smelting furnace, the mixed gas copper smelting furnace has increased coal gas and has produced and combustion processes, with the mixed gas is combustion gas, secondary pressure wind combustion-supporting down, in melting chamber, spray thermal-flame at a high speed, make the high-temperature zone, improved hot service efficiency in melting chamber central authorities, combustiblematerials is fully burnt, avoided high temperature gas flow directly to impact the furnace roof damage that the furnace roof layer is caused.On the technology of refined matte, stoped nuisances such as a large amount of coal ash, cinder to enter in the melting chamber, improved the purity of refined matte liquid.In addition, because the mixed gas generation chamber is totally enclosed, and sufficient combustion, thereby it is very little to the pollution of environment.It is simple in structure, cheap simultaneously, compare with reverberatory furnace and can save coal more than 1/3, and most molten copper reverberatory furnace can be transformed into the mixed gas copper smelting furnace.
