Description

A kind of charging system of furnace cupola

Technical field

The utility model relates to the manufacturing field of furnace cupola, is specifically related to a kind of system reinforced in furnace cupola.

Background technology

Cast iron smelting is one of important step that obtains 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, it is the widest that furnace cupola is 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.Though the molten iron temperature of furnace cupola and Composition Control are easy not as electric furnace, it can satisfy the production requirement of general ironcasting basically, thereby present furnace cupola remains the capital equipment of cast iron smelting.Furnace cupola is a kind of cylindrical shape shaft furnace, removes to be mainly used in iron casting production, also can be in order to cooperate pneumatic steelmaking, being used for copper also sometimes, because of the furnace roof opening upwards, so 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, often main stove is also referred to as furnace cupola in the prior art.Main stove mainly comprises support section and the body of heater that sets gradually from the bottom to top.Support section comprises basis, pillar (stove leg), drop-bottom and bottom door.Body of heater is the major part of furnace cupola; Be seated on the drop-bottom by corresponding pillar supporting; Body of heater is a cylindrical shape, and its shell is processed with steel plate, and the steel plate shell inwall is built into furnace lining (also being provided with refractory lining in the chimney part usually) with refractory material; Wherein, the part from drop-bottom to charge door (also claiming dog-house) lower edge forms burner hearth.Furnace charge is to the impact of burner hearth when feeding in raw material in order to alleviate; Be provided with the crashproof cover of steel (fixing and constitute) by cylindrical body and the ring flange welding that is positioned at the body top on the top of inboard wall of burner hearth; And the lower surface of the ring flange of crashproof cover contacts with the top of the inwall of burner hearth, and the lateral surface of the body of crashproof cover contacts with the top of the inwall of burner hearth.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 the blow-on, closed bottom door, and with the tamping of sand compound as furnace bottom, body of heater be positioned at part around the furnace bottom then as the furnace bottom part of body of heater.Cupola well is meant the part from furnace bottom top to a minimum exhaust outlet of body of heater, and shaft is meant the part from a minimum exhaust outlet to charge door lower edge of body of heater, and chimney then is meant the above part in lower edge of the charge door of body of heater.Is connected through passing a bridge between main stove and the forehearth, passes 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, has 2 to 4 on the air port of main stove is divided and arranges, and every exhaust outlet all evenly distributes along the shaft circumference.Shaft part region also is the combustion zone of furnace cupola, according to the different physical and chemical process that in section up and down, is carried out, is divided into the torrid zone, fusion zone and preheating zone successively according to from bottom to up order in the combustion zone.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: earlier through charging mechanism by charging basket (also bucket) with a part of bed coke by the charge door interior lower floor of cupola well part in the burner hearth of packing into as bed coke.After igniting above the bed coke lower floor; Again remaining bed coke is 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 adding 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.Still carry out the reinforced of furnace charge by charging basket then through charging mechanism; Earlier add the flux lime stone at the bed coke end face; Then in the order adding burner hearth of every barrel of furnace charge according to metal charge, coke charge and flux; Till furnace charge being added to the charge door lower edge, the weight proportion of metal charge, coke charge and flux draws according to the melting rate of stove always.In whole blow-on process; Through constantly replenishing of furnace charge add keep the furnace charge end face from the below lower edge near charge door; Combustion reaction takes place with the upper strata of bed coke in the air in the air port blasts stove; The high-temperature furnace gas that generates upwards flows, and to the furnace charge heating, and makes the layer of metal furnace charge fusing on the bed coke end face.Iron after the fusing drops under the gravity effect drippage downwards, pass through the molten iron passage of levels and gap bridge of bed coke successively after, flow in the furnace chamber of forehearth.When iron drips through the bed coke upper strata, further heated by high-temperature furnace gas and red-hot coke, 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 constant basically, 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 replenishes bed coke, and bed coke height is remained unchanged basically.Becoming high-temperature flue gas after high-temperature furnace gas that produces because of the burning of upper strata bed coke and the metal charge effect 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 feed atmosphere, and another kind is through feeding atmosphere after the dust pelletizing system again.For melting rate is the furnace cupola more than 3 tons and 3 tons; The height of its charge door (length on the above-below direction) is all more than or equal to 2.5 meters; The width of charge door (length on the left and right directions) and chimney internal diameter are close, thus at high-temperature flue gas when flowing through charge door, because the length on the above-below direction of charge door is bigger; 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 also carries a large amount of pernicious gases such as carbon monoxide secretly because of the imperfect combustion of coke, and annual all have the personnel of many foundries to carry out first aid because of anthracemia; Even the generation of dead situation, 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 contains two kinds of chargers, and a kind of is monorail charger, and another kind is guide tracked charger.

Monorail charger mainly is made up 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, drives charging basket with respect to the single track parallel motion by the shaped as frame roof beam structure of walking mechanism again and carries out horizontal movement and got into the body of heater lumen centers and carried out vertically reinforced by the charge door of cupola body sidepiece.So-called vertical reinforced; The flange circle that also is 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 adopted constitutes; After charging basket gets into the body of heater inner chamber; The flange circle that vertically drops to earlier its ladle body is shelved on 2 channel-section steels that laterally arrange as bracing frame in the stove; Thereby make that be positioned at the mechanical controller structure charging basket outside, that lower end and charging basket twoly open that base plate links to each other, the upper end links to each other with suspension hook that the hoist engine steel cable is connected becomes relaxed state by tensioning state; Charging basket is two to be opened base plate and then in bucket, opens under the gravity effect of solid material, and the material in the charging basket just vertically falls into the combustion zone of shaft, and feeding intake finishes again opens base plate through the upper end of the mechanical controller structure of steel cable and suspension hook pulling charging basket with charging basket two by hoist engine and close and drive charging basket immediately vertically upward; Disengage with the stove inner support frame and the segment distance that rises after, again by walking mechanism along single track with the parallel body of heater that shifts out of charging basket.The process that above-mentioned prior art is fed in raw material to furnace cupola has tangible deficiency: at first the charging basket of this kind charger is in the charge door entering furnace cupola by sidepiece; Because the height dimension of charging basket is all bigger usually with the bucket footpath; Add shaped as frame roof beam structure and the height of steel cable and suspension hook of the walking mechanism of monorail charger; Not only cause the height of charge door of sidepiece of furnace cupola big, width is also big (for example melting rate for 10 to 12 tons the material mouth of furnace cupola per hour greatly about 4 to 5 meters high; 1.6 to 1.8 meters wide; Melting rate is that the height of charge door of 3 tons furnace cupola is a 2.5-2.6 rice; Width and body of heater internal diameter are basic identical), cause furnace cupola the time to have more extraneous air to be inhaled into the shaft inner chamber, because of the entering because of the outside air on charge door top of the suction that blower fan produced of thermal current and dust arrester is consumed from the upper space of charge door in operation.Therefore, what make the high-temperature flue gas that produced in the stove has quite a few to flow into the indoor of workshop from charge door, 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 highly higher mostly, and on roof and wall intensive installation ventilating fan, thereby wasted the energy greatly, nonetheless, the anthracemia accident also often takes place.In addition; Charging basket stopping during owing to feed intake to the shaft bore passages; Furnace cupola comprises toxic gas and dust such as a large amount of carbon monoxide, sulfur dioxide because of moving the high-temperature flue gas that is produced continuously; They pour out to the working environment in workshop from charge door, further cause the severe contamination to working environment, and are bigger to site operation personnel's injury.The hopper that Chinese patent document CN2120797U (number of patent application 92211335.1) disclosed " a kind of well formula loading hopper " promptly belongs to monorail charger to be adopted.

Guide tracked charger comprises inclined skip charger and two kinds of versions of tipping bucket type charger.Guide tracked charger mainly is made up of guide rail, truck, hopper and hoist engine.Guide tracked charger is in when work, drag truck by hoist engine and hopper pulled to the charge door of furnace cupola along guide rail, the tipping bucket type charger with hopper in the charge door upset and material is dropped in the furnace cupola.Inclined skip charger then 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.The latter since when reinforced hopper be arranged in the shaft inner chamber; So its shortcoming is basic identical with two shortcomings of monorail charger; And also exist because of pull rope is arranged in the erosion that the shaft inner chamber receives high-temperature flue gas always and damage; Thereby need often to change, there is great potential safety hazard in the careless slightly problem that promptly 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 high-temperature flue gas stop, and have two shortcomings of monorail charger equally; Also, when reinforced, then directly receive the erosion of high-temperature flue gas and damage, thereby need often replacing, carelessly slightly also can rupture because nearer from charge door.Chinese patent document 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 that feeds in raw material from the chimney top of furnace cupola.This charger must cooperate the transformation to the body of heater chimney; Need on the top of body of heater chimney the air inducing equipment by the sidepiece smoke to be set, though when operation, can avoid the problem that flue gas gets into the workshop occurring, the furnace cupola of this structure is not only invested bigger; Energy consumption is higher during operation; And since the position of dog-house higher (can reduce the height of chimney, but higher) than the dog-house position of common furnace cupola cause easily when feeding intake the damage of burner hearth and the fragmentation of coke.

Adopt two furnace cupolas to be used for single shift system production in the general enterprise production process mostly, two furnace cupolas take turns blow-on, every blow-on one day, and another overhauls during a blow-on in two furnace cupolas.Two kinds of above-mentioned main chargers (monorail charger and guide tracked charger) all belong to the separate unit system, and promptly every furnace cupola must be equipped with a corresponding charger, thereby the utilization rate of charger lower (the half the time is in idle state).Secondly the floor space of charger is bigger, thereby the land resource of the preciousness of wasting greatly, and high in addition land price makes the input of enterprise also increase greatly.
