A furnace body is composed of three segments. A water tank (3) is arranged on the circumference of a furnace hearth (2) under the furnace body, the center of the water tank is provided with an observing oxygen conveying pipe (4) and a blast pipe (5) which are communicated with a furnace chamber, and the blast pipe is communicated with a disc wind pipe (10). An annular water-cooled water pipe (12) is arranged on the furnace body, both sides of a furnace top are provided with gas rising pore canals (14) which are communicated with a gas discharging and emitting device (20), a lower pipe (21) of a gas canal, and a chimney by a gas rising pipe (19), and a feed hopper (18) is arranged on the furnace top. When the utility model is used for smelting, oxygen deficiency can not be generated and smelting and sugar melting can not be generated. The wastage of ores is low and is only 5%, and the smelting quality can be ensured. The utility model is used for smelting iron and phosphorus fertilizer.
Description
The utility model relates to iron, phosphorus smelting furnace, particularly a kind of pure fire insulation ironmaking phosphatization dual-purpose stove.
All kinds of smelting furnaces that use in the prior art, all kinds of metallic ores of melting do not reach smart melting, for a long time, the stove tuyere angle unification of all kinds of metallic ores of melting is 0 degree, 0 degree position, air port is not right, there is not simultaneously the oxygen therapy position yet, with anoxic in such ore stove smelting metal stove, can produce the melt of melt melting sugar, cause to condense into the solid metal slag in the stove and be regardless of, the metallic ore 50% becomes slag, iron difference carbon is produced in 50% metallic ore melting, ironworks, Fuquan county, Guizhou Province, ironworks, Wengan County and Wengan County phosphate fertilizer plant, the coagulate solids slag in its iron-smelting furnace and the phosphatization stove adopts explosive, detonator is blown out fryer, makes iron, the smelting cost height of phosphorus, of poor quality.
The purpose of this utility model is: a kind of pure fire insulation ironmaking phosphatization dual-purpose stove is provided, utilizes this stove smelt iron, phosphorus, making the waste of its ore is 5%, reaches to save ore, the qualified purpose of assurance smelting quality.
Formation of the present utility model: by cupola well, shaft, water tank, blast tube, the disk airduct, observe oxygen cathete, the water-cooled water pipe, gas up take, coal gas is put and is sent out device, gas pipe is pipe and hopper composition down, shaft is made up of three joints, following cylindrical cupola well (2) is the first segment shaft, intermediary back taper shaft (9) is the second joint shaft, top positive cone shaft (11) is the 3rd joint shaft, water tank (3) is arranged on the circumference of cupola well (2), observation oxygen cathete (4) and the blast tube (5) that is communicated with burner hearth arranged at water tank (3) center, blast tube (5) is communicated with disk airduct (10), annular water-cooled water pipe (12) is arranged on the circumference of positive cone shaft (11), in semi-round ball furnace roof both sides two coal gas rising ducts (14) are arranged, coal gas rising duct (14) is put a device (20) by gas up take (19) and coal gas and is communicated with, the following pipe of gas pipe (21) puts a device (20) with coal gas respectively and chimney is communicated with, be installed into barrel (17) on the feed port of semi-round ball furnace roof (16) top, the tubaeform hopper (18) of feeding cylinder and top fuses.Water tank (3) is 6, and along cupola well (2) circumference uniform distribution, tank center adopts blast tube (5), the observation oxygen cathete (4) in 33 degree angle air ports, in water tank (3) top water inlet pipe (6) is arranged.Disk airduct (10) is an annular, is supported by the prop (7) that is installed on the furnace shell (13), and disk airduct (10) is connected with gas blower, and is communicated with blast tube (5) by 6 air locks (8).Fly-ash separator puts a device (20) with coal gas and the following pipe of gas pipe (21) is communicated with.
Compared with the prior art, the utility model is simple in structure, can anoxic during smelting, can not produce the melt of melt melting sugar, ore can not condense into the solid metal slag in the stove, and the waste of ore is low, only is 5%, save ore, the not poor carbon of iron is produced in the metallic ore melting, can guarantee the smelting quality requirement.
Accompanying drawing is the utility model structural representation.
Embodiment of the present utility model: as shown in drawings, go up the installation shaft at furnace foundation (1), shaft is made up of three joints, following cylindrical cupola well (2) is the first segment shaft, intermediary back taper shaft (9) is the second joint shaft, top positive cone shaft (11) is the 3rd joint shaft, and shaft jacket is welded into by steel plate, inner lining refractory.Uniform 6 water tanks (3) on the circumference of cupola well (2), there is water inlet pipe (6) the water tank top, there is blast tube (5) in tank center, observe oxygen cathete (4), 33 degree angles are adopted in the blast tube air port, blast tube (5), observing oxygen cathete (4) is communicated with burner hearth, blast tube (5) is communicated with disk airduct (10), disk airduct (10) is supported by the prop (7) that is installed on the furnace shell (13), disk airduct (10) is communicated with blast tube (5) by 6 air locks (8), by gas blower cold wind is blasted disk airduct (10), enter each blast tube (5) by air lock (8) again, send the interior heating wind of cupola well (2) again to, the melting furnace charge.
