Technical field

The utility model relates to a kind of industrial furnace, more particularly, relates to a kind of fuming furnace that reclaims waste residue copper tin.

Background technology

Fuming furnace is the technology that just grows up nineteen thirties, through practice utilization for many years and technological improvement, selects extensively utilization in the smelting industry at tin at present.In lead, zinc, tin smeltery, all materials that contains volatile valuable metal and compound thereof, all available fuming furnace is handled.But existing fuming furnace, metal recovery rate are not high, and productivity ratio is also not high enough, and the fuel consumption of fuming furnace is higher.

The utility model content

The purpose of this utility model provides a kind of fuming furnace, and this fuming furnace can utilize the heat of liquid slag, and metal recovery rate is higher, and the productivity ratio height is easy and simple to handle, available coal and fuelled with natural gas.Its service time is long, and material consumption is few, and expense is low, and the stove of building by laying bricks or stones than general refractory material is durable in use.

The purpose of this utility model is achieved in that

A kind of fuming furnace that reclaims waste residue copper tin, comprise the matrix that is positioned at the bottom, upper fixed at described matrix has carrier frame, above described carrier frame, be disposed with furnace bottom water tank, air port water tank and body of heater water tank, the outside portion of described air port water tank is connected with a plurality of air ports, wherein is connected with two air intake manifolds on the blast pipe at least one air port.

Advantageously, the outside portion of described air port water tank is provided with close-fitting hoop, and the outside portion of described body of heater water tank is communicated with heat material import and cold burden import respectively, and the upper lateral part of described body of heater water tank also is provided with discharging opening.

Advantageously, the distance between described air port and the furnace bottom is 140～250mm.

Advantageously, the angle between described air intake manifold and the blast pipe is 45 °～90 °.

Utilize fuming furnace of the present utility model to obtain rich tin material and matte material, produce, can reach and handle certain manufacturing enterprise's solid waste, make full use of the purpose of resource reutilization for other enterprise from rich tin slag, the poor copper scruff of smelting.In addition, fuming furnace of the present utility model service time is long, material consumption is few, expense is low, and the stove of building by laying bricks or stones than general refractory material is durable in use, and its metal recovery rate is higher, and the productivity ratio height is easy and simple to handle, available coal and fuelled with natural gas.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the schematic diagram of another face of the present utility model.

The specific embodiment

Describe implementation of the present utility model in detail below in conjunction with embodiment.

Referring to accompanying drawing 1-2, the bottom of fuming furnace is the matrix 1 of stove, fixed underpan framework 2 or jack above the stove matrix 1, it on the carrier frame 2 furnace bottom water tank 3, furnace bottom water tank 3 tops are air port water tanks 4, the top of air port water tank 4 is body of heater water tanks 5, there is close-fitting hoop 6 outside portion of air port water tank 4, logical respectively first air port, following side and tertiary air orifice 11, first air port is connected with blast pipe 7, logical respectively heat material import 9 in the outside portion of body of heater water tank 5 and cold burden import 8, upper lateral part has discharging opening 10, there is furnace body support 13 in the outside of whole fuming furnace, and the outer middle side part of furnace body support 13 has airduct 12.

The liquid material of melting furnace or cinder ladle being sent here by slag trough directly joins in the fuming furnace.After the liquid material has advanced heat expected that import 9 blocks.Tin ore, flue dust, piece slag, pyrite and other stanniferous solid cold burdens pass through belt conveyer, disk feeder or manually add in the stoves from cold burden import 8.

The periphery of body of heater also reinforces body of heater with channel-section steel.Body of heater is connected with furnace body support 13 usefulness screws all around, and whole fuming furnace forms solid integral body.

When blow-on, firewood, coke, sludging flux, end slag are dropped in the fuming furnace and light a fire, carrying out slag under the air blast condition smelts, form back unlatching fine coal coal-supply system at slag and high-temperature region, in liquid slag, blast the mixture of air and fine coal, add copper metallurgy scruff material and the flux that matches simultaneously.Tin one steam form in the slag is evaporated, form reduction blowing volatilization process.The tin steam that is evaporated is through the oxidizing fire of secondary combustion chamber and flue, and the rich tin flue dust (〉=40%) that forms tin oxide is recovered as major product in dust collecting system.

Referring to Fig. 2, be connected to two air intake manifolds on the blast pipe in one of them air port, previous air intake manifold is used for the mixture of air intake and fine coal, be called airduct one time, the air intake in back, be called secondary air channel, a common wind accounts for about 1/3rd of total blast volume, and secondary wind accounts for about 2/3rds of total blast volume.Because fine coal and wind coal have strong wearing and tearing to tube wall, so the air port belongs to consumable accessory.For ease of changing, repairing, the air port is connected with water jacket with screw, and between the slit filled stone cotton pad in case leak out, coal.Directly influence the rate of starting of stove the service life in air port, for improving the service life in air port, the part that is badly damaged can be made one section separately, and two ends connect with screw, so that change.When tube wall partly wear and tear as yet mill logical before, load onto still and can use after this section pipe rotated to an angle, every section rotatable several like this, correspondingly tube life-span is long.In addition, the position caliber that a windmill decreases can be enlarged, distinguished and admirable speed is slowed down reduce wear, prolong its service life to reduce impulsive force.Also can change the angle of first and second airduct, as changing 45 ° into by 90 °, but same life-saving.So, just can improve greatly the stove cycle of operation, and keep in repair and change conveniently.Above-mentioned being fit to the fuming furnace of fire coal as main fuel.The most fine coal that use of tin fuming furnace do fuel and reducing agent, and fuel and reducing agent are done in also useful fuel oil or combustion gas.Do the air port of fuel with fuel oil, atomizer is housed, oil is sprayed onto Wen's draw can obtains best atomizing in the air intake duct front.The position of atomizer should avoid the ventilating drill rod of eye.

The distance of air port and furnace bottom is very important, be generally 140～250mm, the excessive then slag of close furnace bottom of distance can not be stirred by wind, coal combustion mixture and seethe, cold burden sinks to the bottom and is difficult for stirring when particularly handling cold burden, cause furnace accretion easily, not only influence the furnace charge fusing, also influence the volatilization effect of tin.Distance is too little, though that melt cinder seethes is effective, the furnace bottom water jacket is subjected to the wearing and tearing of high speed winds coal mixtures and combustion gas and acutely washing away of melt cinder easily and damages.Blast for preventing that the furnace bottom water jacket from burning out, can on the furnace bottom water jacket, build one deck refractory material by laying bricks or stones; Perhaps the furnace bottom web plate directly is supported in the pond and cools off, even steel plate burns, its melt cinder outflow automatically solidifies and blocks.
