Description
Technical field
The present invention relates to metal smelting and particularly smelt plumbous device, specifically, the present invention is a kind of molten lead inductor.
Background technology
At present, the most widely used type of furnace is a market pot in the lead smelting process; Directly coal combustion, Sweet natural gas or producer gas heat for the bowl (bowl of similar cooking) of splendid attire leady raw materials; Adopt lead pump that satisfactory plumbous liquid (lead bullion liquid or lead bullion liquid) is extracted out, carry out next step refining or direct pouring moulding.
The subject matter performance that above-mentioned existing market pot system exists: 1) thermo-efficiency is low, only is about 9.89%; 2) gas unit consumption height, the plumbous gas unit consumption of electricity per ton is about 230m
3About; 3) lead pan is short work-ing life, and the life-span generally has only 6 months; 4) production efficiency is low; 5) produce a large amount of harmful smoke, flue dust CO, CO and in the combustion processes
2, SO, SO
2Deng, contaminate environment; 6) the surrounding enviroment temperature height of stove, workman's operating environment is poor.
According to the test report and the field observation analysis in former years, major cause has:
1) flue gas loss is big.The test report in former years shows that flue-gas temperature is up to 440～445 ℃, and the sensible heat loss that flue gas is taken away is up to 53.86%;
2) flue gas is short at residing time in furnace, causes that the CO volume percent is up to 1.8% in the flue gas, and loss of the inadequacy burning for chemistry mechanics reason is up to 23.36%; This also is the big Another reason of flue gas loss.
3) O in the smoke components
2Volume percent is up to 10.8%, and away from the stoichiometric ratio burning, surplus air is too much, reduced temperature of combustion (average furnace temperature only is 1035 ℃) on the one hand, on the other hand, created good dynamic conditions, aggravated the oxidization burning loss of lead pan basal surface for the bottom of a pan face oxidizing reaction.
4) temperature distributing disproportionation is even in the stove, the localized hyperthermia district occurs, the easy scaling loss peeling of lead pan, and heat flow density is low, and the production cycle is long.
Summary of the invention
The purpose of this invention is to provide a kind of molten lead inductor.This molten lead inductor is at the defective of original technology of melting lead, can save energy, reduce smelting cost, thoroughly a contaminated solution gas purging difficult problem, improve workman's operating environment.
In order to realize above-mentioned goal of the invention, the present invention by the following technical solutions:
A kind of molten lead inductor is provided with iron molten channel mould, is provided with iron core in iron molten channel mould, is tied with coil on iron core, is coated with protective sleeve at coil; Be cast with refractory materials in the described iron molten channel mould outside.
General channel wall is that refractory materials constitutes, and in the plumbous process of melting, the ratio of metallic lead solution is great, perviousness is strong, is easy to infiltrate in the channel wall, and then causes inductor to damage.Be provided with iron molten channel mould among the present invention.Plumbous liquid flows through from molten channel mould, and this iron molten channel mould with plumbous (liquid) chemical reaction does not take place, and its relative permeability is about 1, and magnetic diffusivity, resistivity and plumbous liquid are approaching.Like this, when induction heating, be that plumbous liquid absorbs most electric heating, iron molten channel mould only absorbs very little a part of electric heating.The wall thickness of this iron molten channel mould is 2-70mm.
Described coil is the double-deck square coil that the coiling of solid flat type copper wire bag double insulation forms.
This inductor also is provided with the inductor shell, at the two ends of inductor shell blower fan is housed, and is provided with fan housing in the middle of the inductor shell, forms the air cooling system of coil, iron core.
The inductor shell is welded by steel plate, and flange is whole postwelding planing, boring.
Iron core is a core formula structure, is assembled by processing such as siliconized plate, clamping plate, punching double threaded screw, insulating parts.
Protective sleeve is square stainless steel compacting, is welded, and shaping rear port place embeds insulation strip.
The present invention is by electromagnetic induction, makes furnace charge heating itself, thereby reaches the purpose of furnace charge fusing and insulation.Inductor block is equivalent to a transformer that band is unshakable in one's determination, metal is equivalent to transformer one circle secondary coil in the iron molten channel mould, ruhmkorff coil (being enclosed within on the iron core) is equivalent to primary winding, when passing to industrial-frequency alternating current to primary winding, metal heating, fusing in the iron molten channel mould, then by conduction, convection current etc. metal in the heat transferred burner hearth, thereby make that metal constantly is melted in the molten bath, heat.
The present invention has following advantage:
The invention of this molten lead inductor has changed plumbous tradition and has smelted type of heating: be heated to the electric energy induction heating by fuel.Therefore, do not have additional discharge of harmful gases, pollute and lack, improved the smelting environment, lead pan does not exist oxidization burning loss to prolong the work-ing life of lead pan, has improved thermo-efficiency greatly, has reduced smelting cost, and makes melting and alloying process have better homogeneity.
