Material guide device and have the body of heater of the furnace cupola of material guide device

Technical field

The present invention relates to the manufacture field of furnace cupola, be specifically related to a kind of body of heater and corresponding servicing unit of furnace cupola.

Background technology

Cast iron smelting is one of important step obtained premium casting.The equipment of cast iron smelting has tilting cupola, three joint stoves, electric furnace (electric arc furnaces or electric induction furnace), furnace cupola etc.Wherein, furnace cupola is most widely used, and the ironcasting total output is more than 90%, this be because the characteristics of cupola melting be that equipment is simple, easy to operate, production efficiency is high, can produce continuously, cost is low.Although the molten iron temperature of furnace cupola and Composition Control are easy not as electric furnace, it can meet the production requirement of general ironcasting basically, thereby current furnace cupola remains the capital equipment of cast iron smelting.Furnace cupola is a kind of cylindrical shape shaft furnace, except being mainly used in iron casting production, also can be in order to coordinate pneumatic steelmaking, and being used for copper also sometimes, because of the furnace roof opening upwards, therefore be called furnace cupola.

The general structure of furnace cupola is: mainly comprise main stove, forehearth (also not establishing forehearth), supply air system and charging mechanism, in prior art often by main stove also referred to as furnace cupola.Main stove mainly comprises support section and the body of heater set gradually from the bottom to top.Support section comprises basis, pillar (stove leg), drop-bottom and bottom door.Body of heater is the annulus cylindricality substantially, is the major part of furnace cupola, is seated on drop-bottom, and drop-bottom is again by corresponding pillar supporting.Body of heater is mainly by the cylindrical shape outer cover of steel plate with to be fixed on material on outer casing inner wall be that the furnace lining of refractory material forms (furnace lining that usually also is provided with thinner thickness in the chimney part), and the part on the lower edge that (also claims dog-house) from drop-bottom to charge door of furnace lining is hearth body.The impact of furnace charge to hearth body when reinforced in order to alleviate; on the top of hearth body inwall, be provided with the crash protection circle (be welded to each other fixing and form by the circle body of cylinder hull shape and the tabular flanged plate of horizontal circular ring that is positioned at the circle body top) of steel, and the crash protection circle is contacted with the top end face of the inwall of hearth body, with the top of the inwall of hearth body, is contacted and hung to support and be attached on hearth body by the circumferential lateral surface of its circle body by the lower surface of its flanged plate.Body of heater comprises furnace bottom part, cupola well part, shaft part and chimney part successively according to order from the bottom to top.Before blow-on, shut bottom door, and with the tamping of sand compound as furnace bottom, body of heater be positioned at part around furnace bottom as the furnace bottom part of body of heater.Cupola well refer to body of heater from furnace bottom top to the part of a minimum exhaust outlet, shaft refer to body of heater from a minimum exhaust outlet to charge door under the part on edge, chimney refers to the above part in lower edge of the charge door of body of heater.Between main stove and forehearth, be connected by gap bridge, pass a bridge and be provided with the molten iron passage, the gap bridge mouth of main stove is arranged on the cupola well position of body of heater, and the air port of main stove is divided and had 2 to 4 rows, and every exhaust outlet all distributes along the shaft even circumferential.Shaft part region is also the combustion zone of furnace cupola, according to the different physical and chemical process carried out, is divided into successively the torrid zone, fusion zone and preheating zone according to from bottom to up order in combustion zone in upper and lower section.Around fusion zone, because furnace temperature is high, some occasion, this part be without refractory material furnace lining, and establish annular conduit in the furnace shell outside, lowers the temperature to furnace shell outer wall spraying cooling water.

The course of work of furnace cupola is: first by charging mechanism, by charging basket (also bucket), a part of bed coke is packed into by charge door in cupola well part in burner hearth as the lower floor of bed coke.After igniting above bed coke lower floor, again remaining bed coke added in burner hearth and drop on the top of bed coke lower floor, and be positioned at the bottom of the shaft part of burner hearth, until add to specified altitude (generally more than 1 meter), the bed coke that is arranged in the shaft part is the upper strata of bed coke.Then still by charging mechanism, carry out the reinforced of furnace charge by charging basket, first at the bed coke end face, add the flux lime stone, then every barrel of furnace charge adds in burner hearth according to the order of metal charge, coke charge and flux, furnace charge is added under charge door always along till, the weight proportion of metal charge, coke charge and flux draws according to the melting rate of stove.In whole blow-on process, by constantly supplementing of furnace charge, add the lower edge that keeps furnace charge end face close charge door from below, combustion reaction occurs with the upper strata of bed coke in the air in air port blasts stove, the high-temperature furnace gas generated upwards flows, to the furnace charge heating, and make the layer of metal furnace charge fusing on the bed coke end face.Iron after fusing drops under Action of Gravity Field drippage downwards, after the molten iron passage of the levels of bed coke and gap bridge, flows in the furnace chamber of forehearth successively.When iron drips by the bed coke upper strata, by high-temperature furnace gas and red-hot coke, further heated, it is overheated that this process is called.Along with the fusing of metal charge, the bed of material descends gradually, so at set intervals, adds one barrel of furnace charge, keeps the height of furnace charge substantially constant, and makes whole fusion process carry out continuously.The adding of coke charge in every barrel of furnace charge, its main purpose is the consumption that supplements bed coke, and bed coke height is remained unchanged basically.After the high-temperature furnace gas produced because of the burning of upper strata bed coke and metal charge effect, becoming high-temperature flue gas moves upward outside the furnace roof opening flows out body of heater along the bore passages of body of heater, a kind of is directly to pass into atmosphere, and another kind is by after dust pelletizing system, passing into atmosphere again.For melting rate, it is the furnace cupola more than 3 tons and 3 tons, the height of its charge door (length on above-below direction) all is more than or equal to 2.5 meters, the width of charge door (length on left and right directions) is close with the chimney internal diameter, thereby at high-temperature flue gas when flowing through charge door, because the length on the above-below direction of charge door is larger, part high-temperature flue gas flows into the indoor of workshop from charge door, this does not just win foundry and is in the boundless and indistinct atmosphere of ash throughout the year, and high-temperature flue gas is also carried a large amount of pernicious gases such as carbon monoxide secretly because of the imperfect combustion of coke, annual have the personnel of many foundries to carry out first aid because of anthracemia, even dead situation occurs, this has become casting industry and will solve and unsolved hard nut to crack for a long time.

The charging mechanism of furnace cupola, mainly contain two kinds of chargers, and a kind of is monorail charger, and another kind is guide tracked charger.

Monorail charger mainly is comprised of single track (I-steel), walking mechanism, hoist engine and hopper.The suspension hook vertical-lift charging basket that is rotatably connected on the steel cable of the pulley on the shaped as frame roof beam structure of walking mechanism by passing of hoist engine during work and is connected by this steel cable is to the cupola charging desired height, then by the shaped as frame roof beam structure of walking mechanism, with respect to the single track parallel motion, drives charging basket and carry out horizontal movement and entered the body of heater lumen centers and vertically fed in raw material by the charge door of the body of heater sidepiece of furnace cupola.So-called vertical reinforced, the flange circle that is also the inverted round platform shelly that is connected as a single entity by the ladle body main body of cylinder shelly with from top and ladle body main body of the ladle body of the charging basket that adopts forms, after charging basket enters the body of heater inner chamber, the flange circle that first vertically drops to its ladle body is shelved on 2 channel-section steels that be arranged in parallel as bracing frame in stove, thereby make, be positioned at the charging basket outside, lower end is opened base plate with charging basket pair and is connected, upper end becomes relaxed state with the mechanical controller structure that system for winding engine cable connected suspension hook is connected by tensioning state, charging basket pair is opened base plate and in bucket, is opened under the Action of Gravity Field of solid material, material in charging basket just vertically falls into the combustion zone of shaft, feed intake the complete mechanical controller structure that is pulled again charging basket by hoist engine by steel cable and suspension hook upper end and charging basket two are opened to base plate and close and drive immediately charging basket vertically upward, with the stove inner support frame, disengage and the segment distance that rises after, by walking mechanism, along single track, the charging basket capable of parallel moving is gone out to body of heater again.The process that above-mentioned prior art Cupola feeds in raw material has obvious deficiency: at first the charging basket of this kind charger is that charge door by sidepiece enters in furnace cupola, because height dimension and the bucket footpath of charging basket are usually all larger, add the shaped as frame roof beam structure of walking mechanism of monorail charger and the height of steel cable and suspension hook, not only cause the height of charge door of sidepiece of furnace cupola larger, width is also large, and (for example melting rate per hour is that the material mouth of furnace cupola of 10 to 12 tons is high about 4 to 5 meters greatly, 1.6 to 1.8 meters wide, melting rate is that the height of charge door of the furnace cupola of 3 tons is 2.5-2.6 rice, width and body of heater internal diameter are basic identical), cause furnace cupola more extraneous air to be arranged from the upper space of charge door is inhaled into the shaft inner chamber in when operation, the suction produced because of the blower fan of thermal current and dust arrester is consumed because of the entering of outside air on charge door top.Therefore, what make the interior high-temperature flue gas produced of stove has quite a few from charge door, to flow into the indoor of workshop, even if strengthen the power of the blower fan of dust arrester, also produces little effect.In order to ensure operating personnel's life security, the factory building of many foundries is mostly highly higher, and on roof and wall intensive installation ventilating fan, thereby wasted greatly the energy, nonetheless, the anthracemia accident also often occurs.In addition, charging basket stopping the shaft bore passages owing to feeding intake, furnace cupola comprises toxic gas and the dust such as a large amount of carbon monoxide, sulfur dioxide because moving continuously the high-temperature flue gas produced, they pour out to the working environment in workshop from charge door, further cause the severe contamination to working environment, larger to site operation personnel's injury.Chinese patent literature CN2120797U(number of patent application 92211335.1) disclosed " a kind of well formula loading hopper " namely belongs to the hopper that monorail charger adopts.

Guide tracked charger comprises inclined skip charger and two kinds of versions of tipping bucket type charger.Guide tracked charger mainly is comprised of guide rail, truck, hopper and hoist engine.Guide tracked charger, in when work, drags truck by hoist engine and along guide rail, hopper is pulled to the charge door of furnace cupola, and the tipping bucket type charger is by hopper in the charge door upset and during material is dropped into to furnace cupola.Inclined skip charger drags truck by hoist engine and along guide rail, hopper is pulled in the inner chamber of furnace cupola, opens base plate and to furnace charge.Latter's hopper when reinforced is arranged in the shaft inner chamber, therefore its shortcoming is basic identical with two shortcomings of monorail charger, and also exist because pull rope is arranged in the erosion that the shaft inner chamber is subject to high-temperature flue gas always and damage, thereby need often to change,, there is great potential safety hazard in the slightly careless problem that namely can rupture.For the former, when hopper upset was reinforced, evenly reinforced for making, hopper must have quite a few to stretch in the body of heater inner chamber, so also can form and stop high-temperature flue gas, and have equally two shortcomings of monorail charger; Also because from charge door close to, when reinforced, directly be subject to the erosion of high-temperature flue gas and damage, thereby need often replacing, slightly carelessly also can rupture.Chinese patent literature CN201385952Y(number of patent application 200920020118.5) disclosed " high inclination-angle charger " is a kind of of above-mentioned guide tracked charger.

In addition, also has a kind of charger fed in raw material from the chimney top of furnace cupola.This charger must coordinate the transformation to the body of heater chimney, need the air inducing equipment by the sidepiece smoke be set on the top of body of heater chimney, although can avoid occurring that flue gas enters the problem in workshop when operation, it is larger that but the furnace cupola of this structure is not only invested, during operation, energy consumption is higher, and, due to the position of dog-house higher (can reduce the height of chimney, but higher than the dog-house position of common furnace cupola), while feeding intake, easily cause the damage of burner hearth and the fragmentation of coke.
