Description

The equipment of continuous copper smelting

The present invention relates to extract the equipment of copper with melting copper sulfide concentrate sand.

Shown in Fig. 1 and 2, present known melting copper equipment is formed by a plurality of smelting furnaces.This kind equipment comprises: with inside for oxygen-rich air, oxidizing fusion copper ore concentrates sand, and form the smelting furnace 1 of matte M and slag S within it; The parting furnace 2 that matte M and slag S are separated; Is the transfer equipment of isolating matte oxidation, formation blister copper C and slag S converting furnace 3, and the anode furnace that blister copper C is refined into higher degree copper.Smelting furnace 1 all has a telescoping blowpipe 5 with blow converter at its top, blowpipe inserts from furnace roof, and its mode of connection can make its relative furnace roof for vertical movement.Smart copper ore, oxygen-rich air, fusing assistant etc. are by in blowpipe 5 each stove of input.Parting furnace 2 is electric furnaces of being furnished with electrode 6.

As shown in Figure 1, smelting furnace 1, parting furnace 2 and converting furnace 3 are disposed in order at various height to fall progressively and go up, and continuous in proper order with copper spout 7A and 7B general.Liquation is dirty along these chutes under action of gravity.

The blister copper C interim storage that is continuously produced by blow converter 3 is in holding furnace 8, and the copper water bag 9 of packing into then is sent to anode furnace 4 by crane 10 with copper water bag 9, and injects in the stove by the cast gate on the anode furnace roof.

Therefore, the melting technology till converting furnace 3 is carried out continuously, but anode furnace 4 is to be interrupted operation.This is because the quality of the copper final composition that is it needs the cause that be controlled here.The effect of holding furnace 8 is coordinated this difference in the melting technology.

In Fig. 2, shown in the label L is an example of copper water bag 9 motion track that is sent to anode furnace from holding furnace.In anode furnace, impurity is oxidized and remove from blister copper C, and the cupric oxide that produces in oxidising process then is reduced into the copper of better quality.The finished product casting in bronze that obtains the most at last becomes positive plate after refining arrives higher purity.

In above-mentioned melting equipment, though all carry out continuously up to the operation of converting furnace 3, the refinery practice interruption in anode furnace 4 is carried out.So the blister copper C by converting furnace production must temporarily be stored in the holding furnace 8.Like this, just need the holding furnace device.And, also need blister copper liquid C is sent to from holding furnace the equipment such as copper water bag 9, crane of anode furnace.And, also need expend a large amount of energy in fusion process in order to make blister copper C that sufficiently high temperature be arranged.The result improves the cost of smelting apparatus, and the possibility of reduction smelting apparatus erection space is reduced.

In addition, when inflow of blister copper liquid or outflow copper water bag, produce stronger airflow because of all falling from the higher position.This can make the gaseous state resultant that contains sulfurous gas in the airflow and because the metal mist that factors such as mechanical impact, air expansions suddenly produce, this understands cause injurious effects to environment.So also need effective smog, dust collection device in the big area scope.

Therefore, basic purpose of the present invention and feature provide a kind of copper continuous smelting equipment of novelty, and it need not to be provided with holding furnace between converting furnace and anode furnace; All can implement by very effective continuous mode until the refinery practice that anode furnace carries out.

Fig. 3 has showed an embodiment of copper continuous smelting equipment of the present invention, and wherein the label identical with Fig. 1-2 of Cai Yonging just represented identical with it part or device.

Similar with prior art, the equipment of present embodiment has, a smelting furnace 1 that smart copper ore is melted and is oxidized to matte M and slag S; The parting furnace 2 that matte M and slag are separated; The converting furnace 3 of blister copper is produced in will be from a slag S isolating matte M oxidation; And a plurality of blister copper C with converting furnace production are refined into the anode furnace 4 of higher degree copper.Smelting furnace 1, parting furnace 2, converting furnace 3, has the chute 7A of definite liquation flow path and the chute device of 7B above-mentioned three stoves is linked to each other successively on different heights with the series arrangement that falls progressively.Thereby liquation can flow to parting furnace 2 by chute 7A from smelting furnace 1, flows into converting furnace 3 by chute 7B again.Stove 1 and stove 3 all have a plurality of telescopic blowpipes 5 at its top, blowpipe 5 inserts from top end wall, and it makes it relative furnace roof with the mode of connection at top can do vertical movement.Copper ore concentrates sand, oxygen-rich air, fusing assistants etc. infeed in each stove by these blowpipes.Parting furnace 2 is the electric furnaces that are equipped with a plurality of electrodes 6.

In the present embodiment, two anode furnaces be arranged in parallel, and converting furnace 3 links to each other with these anode furnaces by copper spout device 11.The blister copper liquid C that converting furnace 3 is produced flows into anode furnace 4 through chute device 11.Copper spout device comprises: the liquid outlet of its upstream extremity and converting furnace 3 links, and the sow (channel) 11A that tilts to descend and be provided with from converting furnace 3; A pair ofly be in chute 11B downstream part and that tell from sow (channel) 11A.Each branch from bifurcation tilt to descend, their end links with an anode furnace 4 respectively.

In addition, device 12 is used for guiding selectively sow (channel) 11A and a certain chute 11B of branch sets up liquid conducting relation, and device is built in sow (channel) and the junction of propping up chute.Device 12 can optional construction.Prevailing a kind of form is to make the shallow nest of certain form in the bottom at each chute 11B and the adjacent place of sow (channel) 11A, can be that the agglomerate of refractory material is inserted in the shallow nest part of obsolete that chute with the casting forming thing.

As a kind of replacement of said structure, the conversion of blister copper liquid path can realize with the suitable selecting arrangement that is installed on the chute device 11.Figure 13, the 14th, an example of this screening device.In this example, the downstream of the sow (channel) 11A of inclination partly is open, and a pair of chute 11B of branch is attached thereto by a level part 11C, and the downstream end of sow (channel) 11A is in the top of level part 11C.Selection mechanism comprises a pair of stopping device 40 that places each chute 11B upstream extremity respectively.Each stopping device has: one with make with the liquation same material, and can vertical the placement and close fork chute 11B flow passage close flat board, one by suspension hook 42 and rope with close dull and stereotyped upper end banded lifting mechanism (not shown); One with close dull and stereotyped 41 link, can be to the feed pipe 43a that closes dull and stereotyped internal feed cooling fluid, one with close the dull and stereotyped 41 liquid discharge pipe 43b that link to each other, can close the cooling fluid eliminating in dull and stereotyped.As can know among Figure 14 see, close dull and stereotyped 41 similar with the cross-sectional shape of a chute 11B, but its undersized, intralamellar part has zigzag passage 41a, its two ends 41b, 41c all are opened on the top of closing flat board 41.Feed flow, liquid discharge pipe 43a, 43b link to each other with 41c with opening end 41b respectively removably, and are supported on the suspension hook 42 by web member 44.In order to close a chute 11B with stopping device as mentioned above, cooling fluid will be made by elevator mechanism and close dull and stereotyped 41 and move down and this chute 11B is closed behind feed pipe 43a pilot fluid passage 41a.Though close dull and stereotyped 41 with a chute 11B between slight gap is arranged, the liquation stream by the gap is solidifying with closing can be cooled off rapidly when flat board 41 contacts, the blister copper after solidifying just blocks the gap at the S place, thereby this chute 11B is closed fully.When opening this chute 11B, at first will send into the cooling fluid passage of closing flat board and close, will unload from closing flat board for liquid discharge pipe 43a, 43b then.For after liquid discharge pipe unloads, the cakey blister copper of blocking the gap at S place afterwards, will be closed flat board 41 and be risen by lifting mechanism because the heat of liquation is preached and melted and flow down along propping up a chute 11B.

In addition, except other going out Copper Groove 7A and the 7B, above-mentioned sow (channel) 11A and 11B all add a cover, and the heat-preserving equipment such as well heater and/or surrounding environment atmosphere adjustment device is provided thereon, so that liquation keeps high temperature when these copper spouts under air-tight state.

As Fig. 4-6 best image, each anode furnace 4 includes: a garden cylindricality shaft 21 has partly 21b of housing on the shaft.At the two ends of housing section 21b two end plates 21a is housed, a pair of rim 22 also is housed on the housing section 21b, a plurality of bogie wheels 23 of supporting rim 22 are installed on the substrate.Therefore, the shaft 21 of horizontal supporting can be around its axis revolution.A gear ring 24a is loaded on an end of shaft 21, and with near the driving gear 24b engagement that is installed in the shaft.So shaft 21 can make its rotation easily by drive unit 25.

In addition, shown in Fig. 4 and 5, well heater is installed in an end plate 21a and goes up to keep the high temperature of liquation in the stove.A pair of tuyere 27 is installed on the housing section 21b, in order to air or oxygen-rich air are blown into shaft 21.Outage 28 with tuyere 27 positioned opposite also is housed on housing 21b, and the copper liquid that refined through anode furnace imports casting equipments through outage 28, and casts positive plate at there.On housing section 21b upper half part, also has an opening for feed 29 that is used for the material of positive plate fragment one class is imported stove.As shown in Figure 6, one is generally the top that oval-shaped air outlet 30 is arranged at housing section 30, and its position is relative with well heater 26.Air outlet 30 is the outwards expansion circlewise of determined top shell when stove is in the normal position.

The extraction hood 31 that is positioned at exhaust duct one end covers on the air outlet 30.As being clear that among Fig. 7, extraction hood 31 is expanded to such an extent that can be topped rotate and occupied zone, whole angle position, air outlet 30 with shaft 21.And as shown in Figure 9, a chute 11B of guiding blister copper liquid stream inserts in the limit wallboard of extraction hood 31, and the mode of its insertion makes the end 11C of a chute 11B be positioned at the top of air outlet 30.The end 11C of an extraction hood 31 and a chute 11B respectively is furnished with water jacket J.

To being described below of the melting technology of continual copper smelting equipment of the present invention.

At first, will import smelting furnace 1 by blowpipe 5 with oxygen-rich air as copper ore concentrates sand one class granulated material, the copper ore concentrates sand that enters stove 1 is oxidized partially, and because of the high heat of oxidation generation melts, thereby formed the mixture of matte M and slag S.The fundamental component of matte is cupric sulfide and iron sulphide, and its proportion is bigger.And slag is made up of ore, CHARACTERISTICS OF TAILINGS SAND, fusing assistant, ferric oxide etc., and its proportion is less.The mixture of matte M and slag S passes through copper spout 7A overflow to parting furnace 2 from the leakage fluid dram 1A of smelting furnace 1,

After parting furnace is gone in the mixture overflow of matte M and slag S, because each other proportion difference, be separated into be difficult to mix mutually two-layer.Matte M separates overflow by the siphon pipe 2A that is located at parting furnace 2 leakage fluid dram places, and longshore current groove 7B imports converting furnace 3, slag S from taphole 2B inflow water after the granulation dispatch go out smelting system.

The matte M that imports converting furnace 3 therefrom removes by the further oxidation of oxygen-rich air that is blown into through blowpipe 5 and with slag S.Here, matte M changes into purity and is about 98.5% blister copper, then enters sow (channel) 11A through leakage fluid dram 3A.Owing to from stove 3, contain higher relatively copper content among the isolated slag S, so the slag S that enters granulation the water from leakage fluid dram 3B sends smelting furnace 1 melting once more after drying again back to.

The blister copper C that enters sow (channel) 11A enters one chute 11B.At this moment, another chute 11B is by being cast into its bottom shallow nest and having blocked through-flow relation with sow (channel) with casting thing.Subsequently, blister copper liquid just flows in the corresponding anode furnace through the air outlet.Figure 10 has showed a certain position that anode furnace rotates to.And, when the charging operation, keep this invariant position.

After the blister copper charging end of job, starting drive unit 25 makes shaft 21 rotation one predetermined angulars and arrives position shown in Figure 11, and herein, tuyere 27 is positioned at below the liquation liquid level.On this position, at first air or oxygen-rich air are blown in the stove by tuyere 27, make one section preset time of blister copper oxidation and make the concentration of sulphur in the copper reach the calibration value of a preliminary election.Be that the reductive agent of hydrocarbon and air mixture imports in the stove and carries out restore job then with fundamental component, make the content of oxygen in the copper reach the calibration value of a preliminary election.The waste gas that in said process, produces with through the air outlet 30, extraction hood 31 reclaimed to the mode of waste gas air channel discharging, and it carried out suitable processing.Slag S discharges from leakage fluid dram 29.

Be refined in anode furnace 4 after the more highly purified copper from the blister copper C of converting furnace 3, start drive unit 25 once more and make body of heater rotate a predetermined angular, its situation as shown in figure 12.Copper liquid in it is discharged through discharge orifice 28.The copper liquid of discharging is sent to anode casting through another chute and is molded into positive plate.Then, again positive plate is passed to follow-up refining device.

As mentioned above, in continuous copper smelting equipment of the present invention, blister copper C is directly to transmit passage flow path groove device 11 by blister copper liquid to carry out from converting furnace to the conveying of a certain anode furnace.So need not to be provided with holding furnace, also do not need the operation that it is heated certainly.In addition, also because of no longer needing transportation equipments such as copper water bag, loading lifting mechanism, so the total floor space of melting copper equipment is able to substantial reduction.And because need not holding furnace, Tong Shuibao, loading lifting mechanism etc. are so total cost of this equipment and process cost all can reduce.

Since blister copper C from converting furnace 3 to anode furnace 4 transmission directly carry out via chute device 11, this just makes blister copper (transmit more or less freely under air-tight state.So have only the sulfurous gas of minute quantity and metallic fume to produce.These can cause the leakage of dysgenic gaseous substance to prevent to environment.It is minimum that the temperature variation of blister copper C also can reduce to thus.

In above-mentioned melting copper equipment, be positioned at the top of the air outlet 30 of anode furnace 4 as the leakage fluid dram 11C that props up chute 11B of blister copper flow passage, so air outlet 30 is not only as the outwards outlet of discharging waste gas from shaft, but also as the admission port of blister copper liquid C, in addition, the extraction hood that links to each other with exhaust duct when shaft rotates, all can play cover to residing each the circumferential angle position in air outlet and protect effect.So, can make the structure of this equipment become very simple as the import of blister copper liquid again owing to coming down to requisite air outlet 30.In addition, because the leakage fluid dram 11C of each chute 11B is heated by the high-temp waste gas that well heater 26 burnings generate, equip so need not again it to be installed any insulation.

Because air outlet 30 is along the circumferential expansion of housing section 21b, thus the importing of liquation even in anode furnace rotates the process of an angle, also can carry out, thereby oxidizing process can be carried out simultaneously with the reception blister copper.Compare with the situation of the chute that inserts end plate 21a, the area of shaft opening can also reduce.And even shaft rotates, chute 11B and shaft 21 also can dryly not relate to.

The 11C place, end of propping up chute 11B is furnished with water jacket J, and the intensity of copper spout strengthens owing to standing cooling, thereby has increased the work-ing life of chute.

Two anode furnaces are provided in the present embodiment, and the chute that the blister copper C that converting furnace 3 is produced selects through selecting arrangement 12 only flows in one of them stove.When an anode furnace began to receive blister copper liquid, the blister copper that receives in another stove was in oxidation, reduced and cast positive plate 3.

Below, just the typical operator scheme of plan introduction shown in Figure 15-17 is gone into two anode furnaces 4 comprising receiving blister copper C, oxidation, reduction and casting.The ability of continuous smelting operation is depended in suitable model selection to a great extent, i.e. the balance of the refining of the smelting capacity of smelting furnace and anode furnace and bin stock energy strength.

Ability corresponding to anode furnace shown in Figure 15 surpass the converting furnace ability situation.

When blister copper C was one of anode furnace (a) reception, the blister copper liquid that has entered anode furnace (b) in previous step was then being handled through oxidated, reduction, casting and various corresponding less important work.In this pattern, oxidation was with 2 hours, and reduction was with two hours, and casting operation was with 4 hours.In addition, clean the air port handy half an hour between oxidation and restore job, between reduction and casting operation, did casting and prepare with 1 hour, cast and a next charging operation between with carrying out casting finish half an hour.Like this, be refined to finishing altogether of blister copper material charging work next time from the copper material that receives and need 10 hours.

But it seems on the other hand, receive the blister copper material and need spend 12 hours, and operation total time in the anode furnace is shorter than the used time that receives as mentioned above.So time enough is arranged, in the next round charging to come to finish casting operation.

Figure 16 is corresponding to anode furnace and converting furnace ability situation in a basic balance.Promptly concerning converting furnace, its ability is greater than the situation among Figure 15.In this pattern, be used for oxidation, reduction, casting, and required total times such as the preparation of other non-productive operation before, cleaning foundry goods as cleaning air port, casting identical with premode, be 10 hours.But the time that is used to receive the blister copper material also is 10 hours.So the antianode stove has not just had the waiting time.

What Figure 17 explained is adoptable pattern when the anode furnace ability is lower than the converting furnace ability.In this pattern, for strengthening affinability, in the final stage of blister copper charging, the oxidation operation and the charging operation of blister copper are carried out simultaneously.Or rather, the blister copper charging was finished with 2.5 hours, and needed 9.5 to 10 hours altogether from being oxidizing to casting finish.Because charging operation and local overlapping on the oxidation activity duration, always taking time of various operations just reduced.

Charging and oxidation operation are just carried out when rotate position shown in Figure 11 from position shown in Figure 10 at shaft 21, and after blister copper charging operation was finished, the oxidation operation still continued.

Adopt above-mentioned this work pattern, charging is parallel with the oxidation operation to be carried out, thus the shared pure time of blister refining owing to time-interleaving reduces, thereby the ability of anode furnace has obtained reinforcement.Thereby after smelting capacity increased, the productivity of whole smelting system had all correspondingly improved.

The time course figure of foregoing Figure 15-17 only is some examples of antianode furnace operating technology tabulation expression.And suitable various patterns can be selected according to the quantity of anode furnace and ability and each work step activity duration.In addition, with regard to charging shown in Figure 17 and oxidation activity duration are overlapping, the factors such as oxidation capacity of blister copper productivity, anode furnace with due regard to also.

In aforementioned each embodiment, two anode furnaces 4 all are arranged in parallel each other.Thereby when a standby anode furnace need be set again, the stove that is increased also can be followed simply with original two stoves and is arranged in parallel, and correspondingly set up chute and selection mechanism.

Carry out detailed discussion with regard to the layout of the chute device of the coupled knot of anode furnace below.

Figure 18 has explained the example that anode furnace is arranged, two anode furnace 4A wherein and the set-up mode of 4B and standby anode furnace 4C make their horizontal axis to be located along the same line.Chute device links together converting furnace and each anode furnace 4A-4C.Or rather, two anode furnace 4A, 4B are operations routinely, and both air outlets are arranged to respect to one another.The air outlet of standby boiler 4C can only be arranged adjoiningly with these 2 stoves.Chute device 11 comprises, one end and blow converter 3 banded sow (channel) 11A and a pair of chute 11B, end of each chute all with sow (channel) 11A binding, and the other end respectively with anode furnace 4A, a binding among the 4B.An end and the standby boiler 4C of additional chute 11C are connected in the air outlet, and its other end links to each other with above-mentioned two upstream portions of one that prop up among the chute 11B.Except the selection mechanism 12 that is located at sow (channel) 11A and the point of contact place of chute 11B, be provided with a selection mechanism 12A again at the point of contact place of a chute 11C and coupled that chute 11B.Shown in the number in the figure 45 is the Tong Shuibao that accepts from the slag of body of heater 21a leakage fluid dram discharge.

But in above-mentioned layout, the distance of the anode furnace 4B on the right side and the stove 4C on the left side is greater than the longitudinal length of an anode furnace.Therefore the chute that links converting furnace and anode furnace just becomes oversize.In addition, air outlet 30 and outage 28 be along being positioned opposite on the anode furnace length direction, therefore the outage 28 of two adjacent anode stoves between distance also become greatly, thereby make the casting chute 46 that links pouring device 47 and anode furnace also elongated thereupon.The total floor space of equipment because blister copper chute device 11 and casting groove 46 are all elongated, and make the melting equipment can not be compact, so also just can not effectively be reduced.In addition, because the growth of copper liquid passage, thereby the well heater quantity of setting up also must increase the structure complicated that makes chute device thereupon.Running cost and be in the labor force that sealed state spends and also can increase like this for keeping the copper groove.

In sum, the decoration form of in Figure 19, having showed a better anode furnace and copper spout device.In this decoration form, with the same in aforementioned first embodiment, stove 4A and 4B are parallel to each other opposedly, and standby boiler 4C also is arranged to parallel with above-mentioned two stoves, but slightly to pouring device 47 near.Blister copper chute device 11 comprises: the sow (channel) 11A that the one end links to each other with blow converter 3; One end of a pair of wherein each bar all links to each other with sow (channel) 11A, the other end respectively with the air outlet 30 of stove 4A, 4B in a banded prop up chute 11B.Also have an one end to link to each other, and one one contiguous Upstream section banded add and prop up a chute 11C among the other end and above-mentioned the chute 11B with the air outlet 30 of standby boiler 4C.Except the point of contact place between a sow (channel) 11A and a chute 11B, outside the selection mechanism 12 of setting, the point of contact place between an additional chute 11C and a chute 11B also sets up another selection mechanism 12A.

With regard to arrangement shown in Figure 19, the spacing distance between adjacent two anode furnaces obviously shortens, thereby the bottom line that also just subtracts of the distance between adjacent air outlet.So the blister copper chute length that links to each other with the air outlet is also correspondingly obviously reduced.In addition, because adjacent stove 4A, the liquid outlet of 4B can be arranged toward each other, and casting chute 46 also just can shorten.So whole melting equipment can be arranged very compactly, floor space also just can significantly reduce.Because the minimizing of the well heater quantity of setting up and the simplification of groove structure, running cost and also can reduce for keeping the copper spout to be in the labor force that air-tight state spends.As mentioned above, distance can become very little between the adjacent anode stove, but still is to carry out as operations necessary such as air port processing, feed liquor, discharge opeing operations in the anode sole.

Clearly, still can include within the present invention's spirit scope many improvement of the present invention and modification.So should be appreciated that, within the claims scope, except specifically described content, the present invention can also implement by alternate manner.
