The utility model emits outward for preventing oxide, influences environment and significant loss, and body of heater top is provided with and is used for secondary dust arrester installation that charging aperture, discharging opening are gathered dust.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, operation, easy to maintenance, energy consumption is low, the raw material wide accommodation, when having reclaimed antimony, regained its contained noble metal gold, silver, bismuth, indium, tellurium etc. again, got good economic benefits, the rate of recovery of its antimony is generally more than 85%.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of stilba material melting reverberatory furnace, it comprises body of heater 1, be provided with fire box 2, burner hearth 9 in the body of heater 1, body of heater 1 top is provided with workbench 3, and described body of heater 1 integral body places and is positioned over ground iron case, reduces like this and builds stove cost 15%, be convenient to operation, for next step slagging and antimony alloy have been created condition.Fire box 2 fronts are provided with vent 8, and the bottom is provided with blast orifice 7 and shoot door 6.Former relatively reverberatory furnace vent 8 is located at body of heater 1 both sides, and the middle dead angle of fire box does not have the coal phenomenon in the time of can reducing coal, caking easy-clear, cinder easy-clear between fire.Improve the temperature in the burner hearth 9, risen to about 1350 by original about 1150 ℃, saved coal-fired 20% simultaneously.Body of heater 1 one sides are provided with discharging opening 10, and discharging opening 10 is provided with near burner hearth 9 bottoms, tilt to discharging opening 10 all around in the burner hearth 9, and the gradient is 5.5～6.9 (present embodiment is 5.5).Like this, go into furnace charge and be easy to accept heat, fusion is fast, does not harden, and furnace bottom is concentrated to discharging opening 10, and is easy to deslagging and alloy.For convenient, cleaning door 11 is located at discharging opening 10 tops, and burner hearth 9 tops are arched top, radian 1.2～1.4 (present embodiment is 1.2), and burner hearth 9 tops are provided with charging aperture 4.Like this, improved the anti-holding capacity at burner hearth 9 tops, do not collapsed during charging because of heavy burden.Simultaneously, the arc furnace roof makes burning more abundant, has improved temperature in the thermal efficiency and the burner hearth 9.
For preventing that oxide from emitting outward, influence environment and significant loss during the utility model charging, body of heater 1 top is provided with and is used for secondary dust arrester installation 5 that charging aperture 4, discharging opening 10 are gathered dust.
Stilba material described in the utility model is for containing antimony oxide 4%～45%, contain lead oxide 3%～45%, contain arsenic oxide arsenoxide 3%～50%, contain zinc oxide 10%～20%, bismuth-containing 0.5%～15%, stanniferous 0.5%～5%, argentiferous 0.01%～0.5%, iron content 5%～18% contains indium 0.05%～0.2%, cupric 1%～5% contains tellurium 0.1%～4%.
The utility model when work, step such as it comprises batching, charging, melting, come out of the stove:
Described batching is for by weight, and the addition of every part of stilba material reducing agent is 5%～12%, and the addition of flux is 6%～15%, and the addition of replenishers is 5%～12%.Reducing agent is the charcoal of carbon containing more than 82%, and flux is a kind of or its combination in sodium carbonate, the NaOH, and replenishers are a kind of or its combination in calcium oxide, fluorite powder, silica flour, the potassium oxide.
Charging: smoking cover is moved to charging aperture 4 tops and covered smoking cover, start secondary dust arrester installation 5, earlier reducing agent is added in the burner hearth 9 from charging aperture 4 by the workbench 3 on the body of heater 1, take off flat by proportioning; Add the stilba material be furnished with replenishers again, push away flat, the moisture 5%～8% of stilba material; At last, required flux is covered on the stilba material, shuts cleaning door 11, charging aperture 4, and seal around it with lime slurry.The sealing of discharging opening 10 requires viscosity mud, adds 10% fine sand, adds water 15%, stirs, and makes immobilising bulk.Discharging opening 10 blocks up into that burner hearth 9 is not less than 200mm, is not less than 120mm for the second time, is not less than 80mm for the third time, pushes down with wooden stick at every turn, gently beats wooden stick with iron hammer, to mud and stove brick bonding till.
Melting: at first utilize furnace temperature insulation oven dry 1 hour～2 hours; Be warming up to 500 ℃～600 ℃ (present embodiment is 580 ℃) again, keep 2 hours～3 hours (present embodiment is 3 hours), make volatile matter arsenic quicken volatilization, because arsenic trioxide just is being fit to distillation in this temperature stage, have 60% arsenic trioxide to enter main dust arrester installation 13 by steam vent 12, part lyotrope material begins reduction; Be warming up to 1300 ℃～1400 ℃ (present embodiment is 1350 ℃) at last, keep 4 hours～5 hours (present embodiment is 4 hours), slag is separated with alloy;
Come out of the stove: observe in the stove,, determine the discharging order of alloy and slag again according to raw material condition.Open cleaning door 11, observe in the stove, stir in the stove with instrument, no bulk slagging scorification, slag separates clear with alloy, the upper strata redness, lower floor's silvery white does not have a large amount of white smoke, promptly can come out of the stove.According to raw material condition, determine the discharging order of alloy and slag again.Present embodiment goes out alloy earlier because the product alloy is many.Smoking cover is moved to discharging opening 10 tops and covered smoking cover, start secondary dust arrester installation 5.Present embodiment is with amphidromic cast steel basin, earlier with the 12mm round steel the discharging opening bottom beat inwardly wear after, slowly gently beat again and withdraw from, alloy is flowed in the basin automatically.Alloy cutout is blocked with stifled mud after red slag occurring, and mud is blocked up in discharging opening 10 tops, and slowly to peel off to the stove slag down parallel.Receive discharging opening with amphidromic cast steel basin, slowly a stream of strip off slag road slowly flows in the basin slag, and slag scratches clean stifled mud after going out only, and peace and quiet burner hearth residual alloys and bubble slag are with the stifled good cinder notch of new mud.
The alloy of receiving can obtain required metal by metal smelt.
