Description
Technical field
The utility model relates generally to a kind of rotary charging device, is used for furnace charge is loaded and be distributed in metallurgical reaction (for example being used to produce the blast furnace or the melting gasification furnace of the pig iron).
Now, this feeder typically has following structure.They comprise stationary housing, and this stationary housing is gone up to form in the open top (furnace roof) of reactor drum and sealed (closure).Housing has upper case portion, is generally the form that connects hopper or clack box, and this upper case portion has one or more furnace charge imports and is installed in the top of lower housing part, and this lower housing part is constructed to wheel casing usually.Ring-shaped rotor can be rotatably set in this lower housing part (wheel casing) and supports allocation member, and allocation member is generally the distribution chute of pivot, and said distribution chute is used for furnace charge is dispersed in the reactor drum circumferentially.Feed spout is arranged on the central position in the lower housing part and forms open channel, and this open channel guiding furnace charge passes the centre channel in the rotor and arrives on the allocation member.The example more early of the feeder of this typical types is disclosed in No. the 3693812nd, the USP.
As known in the art, can have different improvement to the swivel supplying working fluid of feeder, estimate (powering) or lubricated control like water-cooled, hydraulic power.The utility model relates more specifically to a kind of improved feeder, and this feeder is equipped with the pipe connection swivel joint, is used for the turning unit accommodating fluid such as rotor and/or allocation member to feeder.Therefore, swivel joint is connected at least one rotating pipe with the rotor rotation with at least one restrained line.The example of this feeder will be described below.
Background technology
For example, in No. the 4273492nd, USP, PAUL WURTH proposes a kind of water-cooling method (seeing this patent Fig. 8) of exposed component of feeder.In this device, rotor has the dividing plate that has been equipped with cooling loop, avoids from the radiogenic heat in the stove to protect it.This cooling loop is arranged in the centre channel ring rotation joint supply coolant on every side in the rotor by coaxial heart.For fear of revealing and allowing for pump circulation and to the loop pressurization, swivel joint has water-proof sealing strip (seal).Ground is quite fast because the wearing and tearing that sizable SFM caused of the relative movement of the sealed strip that major diameter caused of swivel joint, these sealed strips are degenerated.
Invent in No. 4526536 in the U.S., PAUL WURTH has proposed to have the cooling system of a kind of " open swivel joint ", and this opening swivel joint work does not need water-proof sealing strip.In the whole world, this system applies is in a large amount of installation for charging shaft furnace at present.This system comprises on the last circumference that is co-axially mounted on rotor with the last ring groove with the rotor rotation.Fixed port infeeds swivelling chute with water coolant, and swivelling chute is connected to epitrochanterian cooling spiral pipe on this.This spiral tube has outlet pipe, this outlet pipe with furnace charge be discharged into be installed in rotor than in the stationary annular groove on the stationary housing around the lower part.When avoiding sealed strip easy to wear, the shortcoming of this gravity driven cooling system is that the difference of altitude between the groove has limited available pressure, and cooling liqs is exposed in dust-laden furnace air.Because pressure is restricted, though not impossible reach such as high flow rate for fear of the required coolant flow of disadvantageous film boiling, but be difficult to reach.In the place that needs pressure cycling, for example in order to obtain the two-forty of coolant flow, therefore this method is infeasible, particularly under the situation of high-temperature reactor.
Need the cooling of rare gas element or water supply rotor and distribution chute be used for another, PAUL WURTH invents in the U.S. and proposes a kind of chute that is equipped with water or rare gas element cooling channel in No. 5252063.This system also uses and is similar to the U.S. and invents " open swivel joint " in No. 4526536, and it does not allow pressurization.
On the other hand, in the International Patent Application WO 03/002770 of PAUL WURTH, the swivel joint of the pressurization cooling loop on a kind of turning unit that is designed to feeder is proposed.The design of WO03/002770 is the improvement for the design of No. the 4273492nd, USP; The swivel fixed part of its center tap supports with ralocatable mode; And wherein employed sealed strip is not tight, promptly is not (promptly can predict and have leakage in a small amount) of complete waterproof.Therefore, these sealed strips less run into over worn problem.When the authorized pressure circulation and prolonging the work-ing life of sealed strip, between the fixing and swivel of joint, big-diameter water-proof sealing strip need be installed still.Even slower, these sealed strips still can be owing to the major diameter of joint is worn and torn.
In No. the 6481946th, USP, PAUL WURTH proposes a kind of feeder, and hydro-cylinder wherein is installed on rotor, is used to the distribution chute that pivots.Therefore, USP has proposed to be applicable to two kinds of swivel joints (seeing Fig. 3 and Fig. 6 of this patent) of this application specific IC for No. 6481946.Yet, being similar to above-mentioned swivel joint, the swivel joint in No. the 6481946th, the USP also is to be provided with around rotor annular, and therefore has sizable diameter.Therefore, the sealed strip that is used for joint still is easy to wearing and tearing.
Disclose a kind of feeder that is used for shaft furnace in the International Patent Application WO 97/37047, this feeder and above-mentioned modular design differ widely.In the device according to WO 97/37047, the sealed strip of lid and specific type has constituted the top of stove and has sealed.Traditional stationary housing with drive element no longer is provided with conventional rotor.The function of rotor is born by middle storage hopper, and is opposite with convention, and lid is installed and supported to middle storage hopper rotatably with respect to shaft furnace.Therefore, compare with modular design, revolving hopper is supporting distribution chute.Except rotatable and support lid and chute, middle hopper also born himself intermediate storage is provided and as the exemplary functions of sluice chamber (being airtight lock (gas-tight lock)).For this purpose, middle hopper has upper and lower seal valve and material gate valve.
The device of WO97/37047 need be used for EPS cable, be used for the hydraulic pressure supply and be used for water-cooled to extend to the pipeline of revolving hopper, in particular for encouraging down the pipeline of material gate valve, lower seal valve and chute.Therefore, WO 97/37047 is provided with those pipelines and passes the central tubular member, and tubular member passes bell and through spoke, and spoke is connected to tubular member the hopper in the top of revolving hopper.Through its special construction, the feasible swivel joint that can use the small dia at the top that is arranged on tubular member of the device of WO97/37047.But; This device especially has following shortcoming; Promptly include sizable gyrating mass; The payload of storage hopper and Qi Nei material in the middle of these quality comprise, and with the inconsistent quality of the traditional design of feeder member, particularly comprise the wheel casing of the driving mechanism that is used to rotate distribution chute.And, since at the top waterproof type sealed strip of sealing part, in fact only can be used to operate in the low-pressure reactor under the superpressure that is no more than the 0.1-0.2 crust according to the device of WO 97/37047.
Technical problem
First purpose of the present invention provides a kind of feeder that is used for blast furnace, and this feeder can use the pipe connection swivel joint of small dia, avoids simultaneously or reduces the degree according to the shortcoming above-mentioned of the device of WO 97/37047 at least.
Summary of the invention
Contrast with the device of WO 97/37047, as proposing in the independent claim 1, the present invention relates to a kind of feeder that is used for metallurgical reaction, this feeder can use the driving mechanism of type.Therefore the feeder that is proposed comprises that stationary housing, this stationary housing have the lower housing part that inside is equipped with ring-shaped rotor.In known mode, rotor centers on the rotation rotation and has and the co-axial centre channel of rotation.Housing has upper case portion, and this upper case portion has at least one furnace charge inlet from the rotation biasing, and through this furnace charge inlet, feeder can be connected to the upstream device of complete loading device, as is connected to fixing middle storage hopper.
In order to scatter the furnace charge in the reactor drum in known manner, so that rotate with rotor, this rotor can be by the drive mechanism of routine by rotor supports for allocation member (distribution chute of for example installing pivotally).
Feeder also comprises feed spout, and said feed spout is arranged on stationary housing central authorities.Feed spout has open channel, and this open channel guiding furnace charge passes centre channel and arrives on the allocation member.
And; Feeder has at least one restrained line, has a rotating pipe and a pipe connection swivel joint that rotates with rotor at least; This pipe connection swivel joint has fixing part and swivel, and restrained line is connected to rotating pipe so that to rotor and/or the supply of allocation member fluid.
In order to overcome problem above-mentioned, have feed spout according to the feeder of independent claim 1:
-said feed spout has the entrance that is arranged in upper case portion, and stretches into the outlet section in the lower housing part;
-said feed spout is rotatably supported;
-said feed spout is coupled to rotor so that rotate with rotor; And
-said feed spout comprises strut member, and strut member is configured to the swivel of swivel joint and longitudinal axis are supported on coaxially the top of the outlet section of feed spout.
Therefore rotating pipe can extend to any turning unit of the feeder that needs the fluid supply easily via strut member and via the outside of feed spout from the swivel of swivel joint.
This structure provides a kind of mounting means that adopts the small dia swivel joint; Said small dia swivel joint promptly has the joint of the diameter that is significantly less than the passage in the rotor, and said small dia swivel joint can easily be installed with regular supply pipe connection to rotating pipe (a plurality of).The hollow that therefore no longer need customize, swivel joint large-scale and easy to wear.As will understand, in this article, the fixing part of term " joint diameter " expression joint and definite diameter (decisive diameter) of the interface between the swivel (virtual perforation main body).The minimum diameter of free access in width of channel (as observed value relatively) the expression rotor promptly, receives feed spout and/or allows the normal furnace charge required width that flows.Compared with prior art, therefore the present invention can use and have the significantly more swivel joint of small dia.Joint diameter even can be less than the inside diameter of the outlet of feed spout, that is, on diameter less than required minimal flow xsect.
What deserves to be mentioned is that the organization plan that is proposed only need be made amendment aspect feed spout.The scheme that proposes in order to implement, (especially be used to drive the driving mechanism of allocation member aspect) do not need other substantial modification in the feeder parts.
In the first embodiment, said strut member comprises the axle that is fixed to one or more spoke members and supports said axle rotatably and the two special-purpose auxiliary roller bearing of said feed spout.In this embodiment; Feed spout preferably has the mechanical coupling that is associated; For example, unitor in axial sliding, said unitor is connected to said rotor rotatably with feed spout; Even so that feed spout has independently bearing, feed spout and rotor also can rotate synchronously.
In the second different embodiments, the feeding chute is attached to rotor regularly, that is, feeding chute and rotor are by together support.Because rotor rotatably is supported on the main roller bearing, therefore in this embodiment, main roller bearing also supports feed spout.Said skewed slot can be attached to rotor regularly through the one or more crossbeams that in centre channel, radially extend, so that allow all of a sudden to drop on the outside any furnace charge of skewed slot through centre channel.In this embodiment, the fixing part of joint preferably is attached to upper case portion flexibly, so that allow swivel joint with respect to the moving radially of housing, for example, realizes through flexure member and at least two articulated linkage.
As will understand, although axle can be provided, in second substitute mode, do not need axle.For example, swivel joint can directly be installed on the spoke members (one or more).Not considering it is under the situation of which embodiment, if axle is provided, then said axle be preferably hollow and with the longitudinal flume axis coaxle.Most preferably, said axle have the level height place above the skewed slot outlet section be fixed to spoke members (one or more) lower shaft portion and the level height place above the skewed slot entrance arrange on axial region.Thus, if joint covers the perch place, distally on the top of said axle, then said axle and swivel joint can not clashed into.
In the above in two substitute modes, feed spout preferably includes at least two spoke members being fixed to said entrance and is fixed to the annular-flow forming ring of spoke members coaxially with longitudinal axis.Said stream forming ring permission keeps furnace charge and charge distribution is inner to feed spout along circumference, reduces disadvantageous flow velocity when during the skewed slot rotation, crossing entering stream with convenient spoke members and reduces.
Under being arranged in the closed loop cooling loop on the rotor and/or being arranged in by the situation on the skewed slot of rotor supports, pipeline connects through swivel joint.Beginning from swivel joint and finishing on the section of (vice versa) at these pipelines at rotor or in allocation member; These pipelines preferably support (process in the inside of skewed slot support ideally) through skewed slot; And through the outside of feed spout, so that crested and avoid any material bump.
As another preferred feature; Said housing can comprise the circumference dustproof protecting cover; Said circumference dustproof protecting cover puts in rotor channel around feed spout and with the mode with enough gaps, so that the furnace charge outside skewed slot of allowing to drop descends and gets in the passage of rotor.This has been avoided stopping the rotation of feed spout.Preferably, skewed slot puts in rotor channel so that cover rotor and avoids furnace charge with the mode with annular spaces, and to put in the axial distance of rotor channel be at least 50% of channel height to skewed slot ideally.In simple structure, feed spout is funnel shaped, preferably has the outlet section of columniform or downward tapered shape, and has Frusto-conical entrance.
As will understand, the structure that is proposed is specially adapted to have rotation and the feeder of the distribution chute that pivots, and allows to be equipped with the refrigerant supply of the distribution chute of water jacket.In a possible embodiment, feeder (more specifically being the fixedly upper case portion of feeder) has at least two furnace charge inlets of spinning axis bias.In this case, minimum in order to reduce to the influence of furnace charge flow velocity, preferably inlet is arranged in the radially relative position, and is two radially relative spoke members of feed spout outfit.Even three spoke members can provide static going up better to support to skewed slot, but that the interruption that the design that is proposed will not expected is reduced to is minimum, and non-when having avoided two to get into stream and send to through two inlets at the same time simultaneously interrupted simultaneously.On the whole, the geometrical configuration of the quantity of spoke and spoke is preferably corresponding to the quantity and the geometrical configuration of furnace charge inlet.

Embodiment
Fig. 1 part shows the loading device that is used for such as the metallurgical reaction of blast furnace or vapourizing furnace.This equipment comprises feeder, is indicated by reference numerals 100 usually.Rotary charging device 100 comprises stationary housing 102, and this stationary housing has lower housing part 104 and upper case portion 106.In Fig. 1, upper and lower shell body portion the 104, the 106th is with the adjacent independent case body of air tight manner in the connection of flange 107 places.Lower housing part 104 is connected on the flange that the open top (furnace roof) of reactor drum locates.Because reactor drum is normally operated in superpressure, like 2 to 5 crust, housing 102 is set to gas tight casing, and through housing 102, furnace gas can not leak and housing 102 is connected to open top the feed device (not shown) of loading device.
As shown in Figure 1, upper case portion 106 has two radially relative furnace charge inlets 112,114, and they are connected to feeding tube separately from rotation A biasing and with the form that seals.According to the type of loading device and reactor drum, furnace charge through inlet 112,114 from any suitable source (for example middle the storage hopper at the upper reaches) supply or directly from the conveying belt supply.As shown in Figure 1, feeder 100 is constructed to furnace charge stream is guided and is concentrated on the distribution chute 116 along axis A in central authorities.
For this reason, feed spout 120 is set in the stationary housing 102, and the longitudinal axis B of this feed spout is in the center of stationary housing 102.Feed spout 120 is configured to upwards to arrive on the allocation member 116 passing centre channel 110 from the furnace charge stream guiding of 112,114 free-fallings that receive that enter the mouth with all free and open downwards passage.Yet do not get rid of the funnel type structure yet; In the structure of simple and spin balancing; Feed spout 120 has upper inlet section 122; This entrance is formed by hollow frustoconical outer cover, and this outer cover is connected to down outlet section 124 with seamlessly transitting, and outlet section 124 is made into cylinder jacket or cylinder cast or downward tapered tubular form.No matter be which kind of shape, entrance 122 have be applicable to simultaneously from enter the mouth 112,114 receive furnace charge in bulk the large section inlet, yet outlet section 124 has the outlet of small cross-section to concentrate stream 115.
In order directly to concentrate the furnace charge from inlet 112,114, the entrance 122 that upwards broadens is arranged in the upper case portion 106.Outlet section 124 is at least partially disposed in the lower housing part 104.Yet outlet section can be done shortlyer, and the outlet section 124 of feed spout 120 preferably puts in the centre channel 110 and makes rotor 108 avoid furnace charge with cylindrical wall 111 formation circular clearances.As shown in Figure 1, outlet section 124 puts in centre channel 110, and at least 50% the axial square that preferably puts in the height of centre channel 110 leaves, to protect reliably and to improve furnace charge stream 115 concentrating on distribution chute 116.
Further see Fig. 1, upper case portion 106 have in shape with the bottom of frustum of a cone entrance 122 conjugation (conjugated) of feed spout 120.Cylindrical sleeves 125 constitutes the circumference dustproof protecting cover around feed spout 120 with the bottom of upper case portion 106.Cylindrical sleeves 125 also puts in also can be by water cooling in the passage 110.Upper case portion 106 is constructed to leave the circumference space towards feed spout with sleeve 125, and this makes the furnace charge that falls down in entrance 122 outside accidents to fall in the reactor drum through passage 110.
It should be noted that feed spout 120 except guiding function is provided, feed spout 120 is rotatably supported and is engaged rotatably with rotor 108 with respect to stationary housing 102.Supporting feed spout 120 rotatably makes said feed spout can support pipe connection swivel joint 130 (being also referred to as rotary joint or swivel joint); And more specifically make said feed spout can support the swivel 132 of swivel joint 130, this swivel 132 is connected to the fixing part 134 of swivel joint 130 in a fluid tight manner.In the embodiment in figure 1, feed spout 120 is supported by auxiliary roller bearing 129, and roller bearing 129 is arranged on the top cover of upper case portion 106.Fig. 1 only exemplarily shows and is used to advance and returns the two channels radial mode swivel joint 130 that is connected.According to application, swivel joint 130 can be axial or radial mode, and can be single passage or multi-channel structure.
What deserves to be mentioned is that feed spout 120 comprises strut member 140, this strut member has two radially relative spoke members 142,144, and spoke members is radially extended towards axis B from upper inlet section 122 usually, for example with axis B upwards horizontal expansion at an angle.Suitable spoke members the 142, the 144th,, the for example rectangle of hollow or inverted U section.Spoke members 142,144 is fixed in feed spout 120 in its outer end.Spoke members 142,144 is held within it and is fixed in hub 146, more specifically is fixed in the bottom of axle 146.Axle 146 be hollow and extend coaxially with axis B.In the embodiment in figure 1, the sealed strip that axle 146 is passed in the top cover place of upper case portion 106 extends and has top in housing 102 outsides, and the top that the swivel 132 of swivel joint 130 is fixedly mounted in axle 146 is with feed spout 120 rotations.What should be mentioned that is, strut member 140 is supported on the top of outlet section 124 with swivel joint 130, and preferably above entrance 122, to avoid the collision of furnace charge.Swivel joint 130 is coaxial or approximately be co-axially mounted on the top that axis A went up and be positioned at the zone that stream 115 flowed through with axis A, and this main benefit that has is to use little-diameter standard type swivel joint 130.Therefore, there has been sizable growth in the life-span of joint and has realized the reduction of the cost of swivel joint 130 simultaneously.And, even swivel joint 130 can be directly installed on the top of feed spout 120, with swivel joint 130 be installed in housing 102 the outside and on be convenient to safeguard.In addition, the auxiliary roller bearing 129 on the top of axle 146 also is installed in the outside of housing 102, therefore avoids being exposed to gas reactor.
In the embodiment in figure 1, axle 146 has the lower end of the top setting of the outlet section 124 that obviously is positioned at rotatable feed spout 120, reaches minimum with the bump danger that further makes furnace charge.Yet, do not get rid of other structure that is used to support with the swivel 132 of the co-axial swivel joint 130 of longitudinal axis B of feed spout 120 yet.Preferably, tubular shaft 146 can water-cooled, for example the cooling worm (not shown) on swivel 132 through being connected to swivel joint 130 and the cylindrical wall that inwardly is arranged on axle 146.
Like what schematically show among Fig. 1, the pipeline that is connected to swivel 132 is set to begin to extend towards the turning unit that needs accommodating fluid (like rotor 108 and/or allocation member 116) through the outside surface of strut member 140 and process feed spout 120 from swivel 132.In the specific embodiment of Fig. 1-4, each cooling loop like cooling worm, is installed on the rotor 108 cylindrical wall 111 that is exposed to hot gas with cooling, also is installed on the distribution chute 116 simultaneously, and this distribution chute directly is exposed to the hot gas in the reactor drum.
Therefore, in Fig. 1-2 shown in best, rotation is advanced that pipeline 152 and rotation Returning pipe 153 extend and is downward in the outside entering centre channel 110 of entrance 122 and outlet section 124 tubular shaft 146 in, in the spoke members 142,144.In centre channel 110, such as among Fig. 3 shown in the best, rotation is advanced and Returning pipe 152,153 is connected to the entrance and exit that is installed in the cooling loop on the rotor 108 respectively, for example so that cooling cylindrical wall 111.In addition, as shown in Figure 4, rotation is advanced and is connected to the coolant entrance and the outlet of distribution chute 116 with Returning pipe 152,153 respectively, and this distribution chute has the water-cooled sheath.In addition, advance and also be connected to two refrigerating units so that cool off two pivot driver ground chute suspended axles 156,158 with Returning pipe 152,153.Suspended axle 156,158 supports chute 116 and chute 116 is pivoted around axis C and also therefore also is exposed to the hot gas in the autoreactor.The connection of being mentioned is realized by heat resistanceheat resistant and wear-resistant elastic hose; Yet; Rotation is advanced and Returning pipe 152,153 self is then preferably processed by standard pipe, and said rotation is advanced and Returning pipe is installed to allow axial expansion with suspended pattern, for example utilizes the pipe clamp that is fit to.Because outlet section 124 is installed in the lower housing part 104 at least in part, outlet section 124 protection rotating pipes 152,153 avoid flowing to the infringement of the loose material in the feed spout 120.In order to strengthen this effect, outlet section 124 vertical insertion of quite big degree in centre channel 111 is preferred, as shown in Figure 1.
For fear of breaking of rotating pipe 152,153 or the pipe connecting between them, feed spout 120 is engaged to rotor 108 rotatably to rotate synchronously with rotor.In the embodiment in figure 1, this realizes through mechanical coupling (coupling) 160, preferably through axially slidably unitor realization.Mechanical coupling 160 can be that the hinged gangbar (rod linkage) that is fit to or any other drive type fastener, like the inverted U tappet that engages with rotor 108 and axial tappet bore (tappet hole) on the outlet section 124 respectively.Unitor 160 is fixed to rotor 108 rotatably with feed spout 120, makes them rotate harmoniously, although they are by roller bearing 109,129 difference independent support.What deserves to be mentioned is that independently rotation support has avoided swivel joint 130 to break away from the danger of the radial motion of axis.In order further to reduce this danger, auxiliary roller bearing 129 near or preferably close on swivel joint 130 and install, such as among Fig. 1 shown in the best.Although mechanical coupling is preferably, do not get rid of the device that rotor 108 and feed spout 120 are bonded together rotatably, as driving the synchronous auxiliary actuator of feed spout 120 yet.In addition, rotary electric junctor (ring-like like current collection) can be integrated in the swivel joint 130 or be close to swivel joint 130 and be provided with, so that be supplying power such as the electrical components on the swivel of rotor 108 of feeder 100.
As among Fig. 1 further shown in, swivel joint 130 is connected to the fixed forward pipeline 154 of any suitable fixedly cooling loop (not shown) and fixing Returning pipe 155 respectively with rotating pipe 152,153.Yet; Illustrated among Fig. 1-4 and be used for cooling loop is connected the preferred embodiment on the swivel of feeder 100; Should be understood that; Swivel joint 130 can be optionally or additionally is used to connect the loop of other type, for example connects to be used to drive Thrustor so that hydraulic power loop and/or the lubricating loop that pivots according to the chute of No. the 6481946th, USP.
As another notable feature; Feed spout 120 is equipped with annular-flow forming ring (annular flow-shaping ring) 170; Said annular-flow forming ring and axis B are fixed in spoke members 142,144 coaxially, locate (when relative current 115 findings) like downstream, the upper reaches or height (level) at spoke 142,144.Stream forming ring 170 is constructed to so-called " stone box (stone box) ", promptly as the material clasp, wherein keeps one deck furnace charge to avoid wearing and tearing.For this reason, stream forming ring 170 has any suitable cross section, and this cross section is recessed on stream 115 flow direction, the simple L type cross section that goes out as shown in Figure 1.As shown in Figure 2, stream forming ring 170 is constructed to the Closed loop in 360 ° of coverings of circumference, so that intercept the inflow from inlet 112,114 continuously, no matter what position feed spout 120 rotates to.
First function of stream forming ring 170 is to reduce when spoke members 142,144 is passed stream 115, to flow 115 degree that are blocked.For this reason, annular-flow forming ring 170 is positioned at the flow path central authorities that material flows into feed spout 120.Therefore, stream forming ring 170 is used as " spreading machine (spreader) " and causes material to center on axis B and scatter at circumferential direction,, makes the stream expansion that is.Because stream forming ring 170 has been expanded and flowed, therefore the flow resistance that reduced when spoke members 142,144 is passed stream 115 of said stream forming ring is broken.As second function, stream forming ring 170 has reduced and has flowed 115 centrifugal bumps on distribution chute 116, particularly under low flow rate conditions.As shown in Figure 1, this stream forming ring is divided into inside bias current (inward partial flow) and outwards bias current with flow point.Under low flow velocity, these bias currents are above outlet section 124 or internal impact and recombine into the stream that has reduced horizontal rate.As the 3rd function, if two kinds of dissimilar furnace charges fall respectively from each inlet 112,114 simultaneously, annular-flow forming ring 170 has been strengthened the mixing of furnace charge.The mixing of this reinforcement in stream forming ring 170 downstream is above-mentioned each inflow in circumferential distribution and another result of radially cutting apart.
Fig. 5-6 shows second embodiment of feeder 200.In Fig. 5-6, parts identical with the parts shown in Fig. 1-4 structurally and/or on the function are represented by the reference marker that on hundred, increases.Therefore, will only describe main difference and obvious general characteristic below in detail.
In first embodiment, feeder 200 has stationary housing 202, and this stationary housing has the lower housing part 204 that directly is fixed on the reactor head opening.Upper case portion 206 also 212,214 has formed and being tightly connected of upper reaches erecting equipment through entering the mouth.Yet in feeder 200, housing 202 is single structures, and said housing has the upper and lower shell body portion 204,206 that forms single shell.
Feeder 200 also has the specially designed feed spout 220 that is arranged on housing 202 inside.That is, feed spout 220 also centers on its longitudinal axis B rotation and comprises that strut member 240, this strut member are constructed to the swivel 234 of pipe connection swivel joint 230 is supported on lower housing part 202 tops coaxially with axis B.Strut member 240 also has axle 246, and the top of axle 246 is supported on housing 202 tops with swivel joint 230.Stream forming ring 270 also is fixed on the spoke members 242,244 of strut member 240.
Yet, with Fig. 1-4 relatively, feed spout 220 links to each other with rotor 208 through one or more crossbeams (for example radially relative crossbeam 262,264) regularly, such as Fig. 6 shown in the best.Crossbeam 262,264 passes passage 210 and radially extends and circumferential interval, between crossbeam, passes through and drops in the reactor drum to allow accidental furnace charge from feed spout 220 outside processes.The end separately of crossbeam 262,264 firmly is fixed in outlet section 224 and is fixed in rotor 208 (for example being fixed in the lower region of cylindrical wall 211).Preferably, crossbeam 262,264 is arranged in the lowermost region of passage 210 so that extra thermoshield to be provided.Connected firmly by crossbeam 262,264, feed spout 220 forms one-piece construction with rotor 208 and rotates.Therefore, do not need independently roller bearing.The main roller bearing 209 of rotor 208 is also supporting feed spout 220, and the longitudinal axis B of feed spout overlaps with rotation A.
In order to allow the less of swivel joint 230 to move radially; The fixing part 234 of swivel joint 230 is connected to the top cover of upper case portion 206 through flexure member 280, and this moving radially possibly caused by the axial distance of swivel joint and roller bearing 209 and rock (play) of roller bearing 209.Flexure member 280 is the resistance to air loss corrugated tube preferably, i.e. bellow expansion joint (being called compensator usually), and said resistance to air loss sylphon seal ground is connected to the open top of upper case portion 206 with swivel joint 230, to avoid gas leakage.For fixing part 234 axially is fastened to stationary housing 202, promptly for the pressurized (pressure-induced) that limits flexure member 280 expands, two or more articulated linkage 282 are fastened on mounting flange on the top cover of upper case portion 206.Fixing part 234 is fixed on this mounting flange, and is as shown in Figure 4.If expectation protection flexure member 280 is not influenced by torsional load, one or more tangentials connecting rod (not shown) preferably is set so that fixing part 234 is fixed on the housing parts 206 rotatably.The airtight sealing bar preferably is arranged between the axle 246 of fixing part 234 and strut member 240, for example at the mounting flange place, so that swivel joint 230 and housing 202 interior Reaktionsofen air bounds are left.
Fig. 7 shows the feeder 300 according to the 3rd embodiment, and this feeder is the modification of Fig. 1 to Fig. 4.The central feed spout 320 of this feeder also rotatably supports around the longitudinal axis B of this feed spout through auxiliary roller bearing 329 independently.Auxiliary roller bearing 329 also is installed on the top of upper case portion 306 and the next-door neighbour be positioned at pipe connection swivel joint 330 below.Therefore, can be easily near roller bearing 329 and swivel joint, and protection roller bearing and swivel joint avoid the bump of furnace charge.Further, the top cover through upper case portion 306 and the sealing member or the packing ring that support between the axle 347 of feed spout 320 make said roller bearing and swivel joint avoid furnace gas.Although doline feed spout 320 has independently bearing, but this feed spout also is coupled to the rotor in the lower housing part (not shown) rotatably.Thus; The bottom at lower housing part (not shown) place of this feeder has like above referring to figs. 1 through configured parts and function as described in Fig. 4; Particularly, at the expectation fluid supply loop of any kind of on the rotor and/or on allocation member.Fig. 7 only shows the change of upper case portion 306.
Like visible among Fig. 7, strut member 341 has the configuration of variation.This strut member has radially relative spoke members 343,345, and said spoke members upwards extends laterally to higher level height place towards axis B, that is, and and through longer expanded range and have more the angle that tilts.Stream forming ring 370 has and same configuration and the function of Fig. 1-Fig. 4.Only to attached adjust of this stream forming ring with the spoke members 343,345 that more tilts.Under the situation of using longer spoke members 343,345, to compare with Fig. 1 to Fig. 4, the axle 347 that carries feed spout 320 and swivel joint 330 can have significantly littler length.Preferably, for example the diameter of roller bearing 329 axle 347 and this axle must be bigger situation under, this configuration can for example be used to increase the stability of rotatable feed spout 320.Even have large diameter axle 347 and bearing 329, also can use the small dia swivel joint 330 of buied type that can be suitable.In fact, the swivel joint 330 of one or more required pipe connection to rotors must do not had the major diameter identical with axle 347, like Fig. 1 and seen in fig. 7.Particularly, swivel joint 330 can have the medially interior small rotation parts 332 of top front end of installation shaft 347.Structurally and/or on the function with Fig. 1 to Fig. 4 in the identical miscellaneous part (especially assembling pipe joint) of those parts no longer be repeated in this description and the corresponding reference number indication through hundred increases.
Fig. 8 shows the feeder 400 of another embodiment subsequently.The modification of the device 200 that this feeder 400 is Fig. 5 is wherein revised the layout of the small dia swivel joint 430 that is used for pipe connection.More specifically, Fig. 8 shows another that be used to support turning unit 432 and possibly construct.Different with embodiment before, swivel joint 430 is installed in 406 inside, top of housing 402.This makes need not use axle in the embodiment of front and the sealing member that is mainly used in air seal.As seen in fig. 8, swivel joint 430 is directly installed on the top of inclination spoke members 443,445, and the structure of the spoke members among said spoke members and Fig. 7 is identical, and becomes the angle less than 45 ° with vertical axis A or B.Thus, although there is not axle, swivel joint 430 still is arranged in the uppermost position in the housing 402, in the relative crested of swivel joint described in this position.Housing 402 can be integral type or modular construction, but shown in Fig. 8 is modular construction.Through with the top identical device of describing with reference to Fig. 5 of those devices, feed spout 420 is attached to rotor (not shown among Fig. 8) regularly so that need not the auxiliary roller bearing.Therefore,, also allow swivel joint 430 to move radially with respect to the small of housing 402 although do not need independently roller bearing, this be because have towards axial distance and the play (referring to Fig. 5) in the main roller bearing at rotor.Use similar but inverse layout, so the fixing part 434 of swivel joint 430 is attached to the open-topped upper flange in the upper case portion 406 flexibly with the layout shown in Fig. 5.As seen in fig. 8, flexure member 480 is connected to independently mounting flange or mounting plate 481 with fixed upper case portion 406, said mounting flange or mounting plate support fixation elements 434 and with respect to fixing this fixing part of the mode of housing 402 rotation.As shown in Figure 5, flexure member 480 can be a loop expansion pipe.Two or more articulated linkage 482 are with mounting plate 481 and the fixing part 434 of swivel joint 430 axially is fastened to housing 402 thereupon.One or more tangentials connecting rod (not shown) can be set to stop any possible rotation of fixing part 434.Yet turning unit 432 directly is installed on the spoke members 452,453, so that along with feed spout 420 and therefore along with the rotor that requires the fluid supply rotates jointly.Fixed advance pipeline 454 and fixed Returning pipe 455 from fixing part 434 through and pass the sealed open the mounting plate 481 and arrive housing 402 outsides.Although swivel joint 430 is exposed to the not too good environment of housing 402 inside, this embodiment can reduce cost of investment through the gas-tight seal of saving liability fraying, extra axle and extra auxiliary bearing.Because the special tectonic of inclination spoke members 452,453 and housing 402, swivel joint 430 still is in the position of relative crested, and easily contacts to safeguard through only removing mounting plate 481.Yet the embodiment with Fig. 1 to Fig. 7 of seal shaft 146,246,347 obviously has extra advantage, promptly allows under the situation that does not make the stove step-down, to safeguard.
At last, will sum up several advantages.The foregoing description can both use little-diameter swivel joint, this swivel joint is used for the swivel accommodating fluid of the feeder in the loop (like water cooling labyrinth, hydrauliccircuit, lubrication circuit) to any desired type.Particularly, the structure that is proposed makes it possible to utilize the low wearing and tearing of standard type swivel joint that heat exposure (heat exposed) part of feeder is carried out high speed/high tension loop water-cooled.In addition, the structure that is proposed avoids swivel joint to be exposed to the reaction furnace gas, thereby has further increased the life-span of joint.
