Abstract
The invention relates to a wind-coal mixed blowing fuming furnace comprising a furnace hearth (1), a furnace body (2) and a furnace top (3), wherein tuyere rows (8) are arranged at both sides of the furnace body (2); the tuyere rows (8) are connected to a coal feed mixed blowing device by a wind-coal pipe (9); and the coal feed mixed blowing device comprises a pulverized coal bunker hopper (10), an electric control coal discharging machine (11), a first-level coal mixed box (12), a horizontal auger delivery pipe (13), a vertical auger delivery pipe (14), a second-level coal mixed box (15), an electric control coal distribution machine (16) and a wind-coal mixed pipe (17). The wind-coal mixed blowing fuming furnace is high in hearth efficiency, long in service life, low in labor intensity and continuous in work.
Description
Technical field
The present invention relates to the pyrometallurgy equipment in a kind of nonferrous metallurgy field, specifically the mixed fuming furnace that blows of a kind of wind coal.
Background technology
At present, domestic and international plumbous field of smelting, realizes plumbous zinc separation for last containing zinc smelting slag, is to adopt fuming furnace reduction fuming to reclaim mostly.Prior art is used fuming furnace general work-ing life is short, labour intensity large, dangerous high.Fuming furnace adopts molten steel cover to be assemblied to form, fine coal blasts from air port, owing to giving fine coal passage and high pressure air blast pipeline connection, fine coal is mixed inhomogeneous by " string wind " fine coal in mixed coal case, cause fuming furnace tuyere to enter coal inequality, affect reduction effect, even cause dead stove, or bombing, work-ing life, short production efficiency was low.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provides a kind of wind coal to mix and blows fuming furnace, and specific capacity is high, long service life, and labour intensity is low, and operation is continuous.
In order to solve the problems of the technologies described above, technical scheme of the present invention is that a kind of wind coal is mixed blows fuming furnace, comprises cupola well, shaft and furnace roof; In cupola well, one end is provided with siphon slag-drip opening and puts plumbous mouthful; Furnace roof is provided with solid-state charging mouth, and shaft one end is also provided with liquid charging opening; Shaft both sides are provided with tuyere row respectively, and this tuyere row connects coal supply mixed injection device by wind coal pipe.
Described coal supply mixed injection device comprises the fine coal magazine, automatically controlled lower coal machine, one-level mixed coal case, flat spin transfer lime, vertical spin transfer lime, secondary mixed coal case, automatically controlled coal blending machine and the wind coal mixing tube that connect successively; Described one-level mixed coal case is arranged on a platform being supported by four pressure transmitters, and the electrical signal of four pressure transmitter outputs is processed to amplify through micro-chip and is converted into control signal, drives the control electric motor of automatically controlled lower coal machine; Between described secondary mixed coal case and automatically controlled coal blending machine, be connected with lock airduct.
When the present invention processes liquid lead retailoring slag, liquid lead retailoring slag adds continuously from the mixed liquid charging opening that blows fuming furnace shaft one end of wind coal, oxygen-rich air and fine coal blast in stove melt from the tuyere row of shaft both sides, oxygen-rich air violent stirring melt, makes lead, zinc in melt be become lead steam and zinc fume to enter in flue gas by fast restore.
Adopt structure of the present invention, due to coal supply mixed injection device, fine coal, through automatically controlled lower coal machine and the control of one-level mixed coal case, has been realized to coal amount quantitative; Between secondary mixed coal case and automatically controlled coal blending machine, be connected with to lock airduct, solved " string wind " mixed coal case problem, wind, coal mix, and make to reduce the flue gas S0 of fuming
2relative concentration is stable, is more conducive to operation and produces continuously.And specific capacity is high, long service life, labour intensity is low.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Mark in accompanying drawing is: 1 cupola well; 2 shafts; 3 furnace roofs; 4 siphon slag-drip openings; 5 put plumbous mouthful; 6 solid-state charging mouths; 7 liquid charging openings; 8 tuyere rows; 9 wind coal pipes; 10 fine coal magazines; 11 automatically controlled lower coal machines; 12 one-level mixed coal casees; 13 flat spin transfer limes; 14 vertical spin transfer limes; 15 secondary mixed coal casees; 16 automatically controlled coal blending machines; 17 wind coal mixing tubes; 18 platforms; 19 lock airducts.
