In order to see the section configuration that is provided with choke section 4 and choke section 5 places clearly, special profile with the A-A among Fig. 2 and Fig. 3 (rotation) is plotted among Fig. 4.
As can be seen from Figure 4, hood configuration 2 is by upper cover plate 2-1, sealing mechanism 2-2 (specifically in the present embodiment, it is the sealing mechanism of hydrolock), cover plate 2-3 constitutes down, and simultaneously, this hood configuration 2 is sealed, and is containing leaking out of central cooler and be with 7; Hood configuration 3 is by upper cover plate 3-1, sealing mechanism 3-2 (specifically in the present embodiment, it is the sealing mechanism of hydrolock), cover plate 3-3 constitutes down, and simultaneously, this hood configuration 3 is sealed, and is containing leaking out of central cooler and be with 8.In present embodiment and Ben Tu, upper cover plate 2-1 and 3-1, following cover plate 2-3 and 3-3 have utilized the part-structure spare of central cooler to form, and certainly, also can independently make and install.In choke section 4, be provided with choke body 4-1 and 4-2; In choke section 5, be provided with choke body 5-1 and 5-2, purpose is to prevent along the inleakage of the circumferencial direction of hood configuration 2 and 3 excessive.
It can also be seen that from Fig. 4 choke body 4-1 and 5-1 and choke body 4-2 and 5-2 have box structure, and the centre has dividing plate, leak out along its hollow space preventing.In Fig. 4,2-2-1 and 3-2-1 are respectively the water seal cuttves of sealing mechanism 2-2 and sealing mechanism 3-2; 2-2-2 and 3-2-2 are respectively the water sealed tanks of sealing mechanism 2-2 and sealing mechanism 3-2.
It should be noted that water sealed tank and choke body place should reserve enough gaps (shown in the size H among Fig. 4) with the rotating part of central cooler, with the interference that prevents to cause owing to manufacturing, installation, distortion and operation errors etc.It is also to be noted that the size H that indicates among the figure only has the character of example, is not position whole that need leave the gap.
In order to see the section configuration at non-choke section place clearly, special profile with the B-B among Fig. 2 and Fig. 3 (rotation) is plotted among Fig. 5.The difference of Fig. 5 and Fig. 4 only is: in Fig. 5, there are not choke body 4-1,4-2,5-1 and 5-2, all the other, then identical with Fig. 4.
It can also be seen that through present embodiment and Fig. 4, Fig. 5; Described water seal 2-2 of mechanism and 3-2 are arranged in the wheel 1-3 of wheel-grate board component of circumduction part of central cooler with beyond the outer wheel 1-4 of the circumduction part wheel-grate board component of central cooler, and below the interior annular ring 1-5 of revolution brace summer and outer ring circle 1-6.Simultaneously, in the present embodiment, described hood configuration is complete annular.
Present embodiment is a kind of variation of on the basis of embodiment 1, carrying out; The main difference of it and embodiment 1 is: it is to locate in the gap (for example shown in the size H among Fig. 4) that the choke section keeps on the choke section specifically, and flexible deep bead has been installed; All the other, then identical with embodiment 1.In the present embodiment, the deep bead of described flexibility is to adopt silicon rubber to process, still, do not get rid of yet and adopt other rubber to process, and other heat resistant rubber particularly, simultaneously, it can also adopt that rubber-like sheet metal or metal forming are processed etc.
Fig. 6 be on the basis of Fig. 4, increased flexible deep bead 9 later situation.Because the needs of structure, deep bead 9 is divided into many, and with its remember respectively do 9-1,9-2,9-3 ... Or the like.Owing in Fig. 6, be difficult to differentiate its details, therefore, the enlarged drawing of A portion among Fig. 6 and B portion is plotted in respectively among Fig. 7 and Fig. 8; As for situation, can infer thus at other position.
In Fig. 7, deep bead 9-1,9-2,9-3 ... Respectively by pressing plate 10-1,10-2,10-3 ... Be fixed on the choke body 5-1.In Fig. 7; That comparatively special is deep bead 9-4 and pressing plate 10-4 thereof; It is the circumferential directions along water sealed tank 3-2-2, and crosses over discharge port 6 and two place's choke sections 5 (discharge port 6 and two place's choke sections 5 are as shown in Figure 1), to stop from leaking out in the water sealed tank 3-2.
In Fig. 8, deep bead 9-10,9-11,9-12 ... Respectively by pressing plate 10-10,10-11,10-12 ... Be fixed on the choke body 5-2.
In order to see the concrete structure state of deep bead clearly, in Fig. 9, be that example has carried out further describing, and will be plotted among Figure 10 by the enlarged drawing of the section configuration of section plane K gained with deep bead 9-1 and 9-2.Can find out that through Fig. 7 and Fig. 9 the adjacent of deep bead 9-1 and 9-2 is with hypotenuse 11 boundary.
Also being in order to see the concrete structure state of deep bead clearly, in Figure 11, is that example has carried out further describing with deep bead 9-10 and 9-11, also will be plotted among Figure 10 by the enlarged drawing of the section configuration of section plane K gained.Can find out that through Fig. 8 and Figure 11 the adjacent of deep bead 9-10 and 9-11 is with horizontal sides 12 boundary; It should be noted that in Figure 11 the part that deep bead 9-11 bottom is had step has given omission.
In Fig. 9 and Figure 11, the deep bead 9 of the flexibility of demonstration is twice, and in fact, its road number can also be more or less; Suggestion is provided with 3～6 roads for well on each choke body.
All the other contents can be understood from the relevant explanation of embodiment 1.
Present embodiment is a kind of variation of on the basis of embodiment 1, carrying out, and the implication of the label of explanation is not identical with embodiment 1 yet again.The main difference of it and embodiment 1 is:
1. hood configuration 2 and 3 is broken off at discharge port 6 places, to reserve enough spaces, is convenient to the maintenance of chassis.
2. the sealing mechanism 2-2 and the 3-2 that are comprising in the hood configuration 2 and 3 have used the 2-4 of mechanism and the 3-4 of elastic plate-slide type instead.
Figure 12 is the vertical view of present embodiment, has shown the situation that hood configuration 2 and 3 is broken off at discharge port 6 places.It should be noted that and break off hood configuration 2 and at 3 o'clock,, need keep the continuity of one of elastic plate or slide plate at least in order to keep the continuity of sealing mechanism; In the present embodiment, the continuity that has kept slide plate.
Owing in Figure 12, be difficult to differentiate its details, therefore its P portion and Q portion amplified, respectively like Figure 13 and shown in Figure 14.From Figure 13 and Figure 14, can find out the spacing M between the adjacent outer wheel 1-4 of the length L 1 >=central cooler of the choke section 5 on the circumferencial direction of hood configuration 3; And the spacing N between the adjacent interior wheel 1-3 of the length L 2 >=central cooler of the choke section 4 on the circumferencial direction of hood configuration 2.
In order to see the section configuration that is provided with choke section 4 and choke section 5 places clearly, special profile with the C-C among Figure 13 and Figure 14 (rotation) is plotted among Figure 15.
As can be seen from Figure 15; Hood configuration 2 is to be made up of upper cover plate 2-1, sealing mechanism 2-4 (specifically in the present embodiment, it is the sealing mechanism of elastic plate-slide type), middle coaming plate 2-5 and following cover plate 2-3, simultaneously; This hood configuration 2 is sealed, and is containing leaking out of central cooler and be with 7; Hood configuration 3 is by upper cover plate 3-1, sealing mechanism 3-4 (specifically in the present embodiment; It is the sealing mechanism of elastic plate-slide type), middle coaming plate 3-5 and following cover plate 3-3 constitute; Simultaneously, this hood configuration 3 is sealed, and is containing leaking out of central cooler and be with 8.In present embodiment and Ben Tu, upper cover plate 2-1 and 3-1, following cover plate 2-3 and 3-3 have utilized the part-structure spare of central cooler to form, and certainly, also can independently make and install.In choke section 4, be provided with choke body 4-1 and 4-2; In choke section 5, be provided with choke body 5-1 and 5-2, purpose is to prevent along the inleakage of the circumferencial direction of hood configuration 2 and 3 excessive.
It can also be seen that from Figure 15 choke body 4-1 and 5-1 and choke body 4-2 and 5-2 have box structure, and the centre has dividing plate, leak out along its hollow space preventing.
It should be noted that the corresponding site of choke body place and hood configuration 2 and 3, should reserve enough gaps (shown in the size H among Figure 15), with the interference that prevents to cause owing to manufacturing, installation, distortion and operation errors etc. with the rotating part of central cooler.It is also to be noted that the size H that indicates among the figure only has the character of example, is not position whole that need leave the gap.
In order to see the section configuration at non-choke section place clearly, special profile with the D-D among Figure 13 and Figure 14 (rotation) is plotted among Figure 16.The difference of Figure 16 and Figure 15 only is: in Figure 16, there are not choke body 4-1,4-2,5-1 and 5-2, all the other, then identical with Figure 15.
Because in the present embodiment, hood configuration 2 and 3 is broken off at discharge port 6 places, and in order to see the situation of gap clearly, special enlarged drawing with the R portion among Figure 12 is plotted among Figure 17.As can be seen from Figure 17; Because upper cover plate 2-1 and all double slide plate of being among sealing mechanism 2-4 and the 3-4 of 3-1; Therefore; They are to have kept continuously, and hood configuration 2 is broken off at discharge port 6 places with all the other parts (removing slide plate part, middle coaming plate 2-5 and 3-5 and time cover plate 2-3 and 3-3 in addition among sealing mechanism 2-4 and the 3-4) of 3; That is to say: described hood configuration is the part in the complete annular, and more particularly, described hood configuration is most in the complete annular.
For the concrete structure of the sealing mechanism 3-4 that sees elastic plate-slide type clearly, special S portion enlarged drawing among Figure 15 is plotted among Figure 18; Need to prove herein,, so just no longer sealing mechanism 2-4 has been carried out repeat specification because the sealing mechanism 3-4 of the sealing mechanism 2-4 of elastic plate-slide type and elastic plate-slide type is similar.As can be seen from Figure 18, the sealing mechanism 3-4 of elastic plate-slide type comprises slide plate 3-4-1, elastic plate 3-4-2, pressing plate 3-4-3 and housing screw 3-4-4.Wherein, slide plate 3-4-1 and aforesaid upper cover plate 3-1 have incorporate characteristics, and upper cover plate 3-1 has dual function in other words, holds two duties; And in the present embodiment, elastic plate 3-4-2 is processed by silicon rubber, and its basic configuration is curved.In addition, because central cooler adopts the mode of the air blast from the bottom usually, therefore, its arc is aduncate, to improve its sealing effectiveness by means of blast; Simultaneously, elastic plate 3-4-2 should have enough thickness or rigidity, in order to avoid under the effect of blast, opened by drum, in case of necessity, can also realize preventing to be roused the purpose of opening through its shape of conversion and/or structure.
In order to see the thin portion structure of elastic plate 3-4-2 clearly, the spy is plotted in the T portion enlarged drawing among Figure 18 among Figure 19.As can be seen from Figure 19, elastic plate 3-4-2 comprises elastic plate body 3-4-2-2 and wearing layer 3-4-2-1.In the present embodiment, wearing layer 3-4-2-1 adopts be through nitrogen treatment, the sheet metal of thickness ≈ 0.3mm processes, and adopts bonding method to be laid on the elastic plate body 3-4-2-2.
The method that wearing layer 3-4-2-1 is laid on the elastic plate body 3-4-2-2 is a lot, except the method that has explained the front, in Figure 20; Represented a kind of laying method again: it is the wearing layer with sheet; For example 3-4-2-1 after the bending, uses nail (containing screw) to be fixed on the elastic plate body again; 3-4-2-2 for example, on.On the length direction of elastic plate body, why be made into the bending of ear shape, be in order to reduce the crooked ability of its opposing, make every effort to its with slide plate fit better.
In the present embodiment, flexible deep bead also can be installed; Because the front was introduced about the details that flexible deep bead is installed, therefore, just do not given unnecessary details at this.
Present embodiment is applicable to that hot blast that collection discharges from central cooler is to utilize the situation of its heat energy.The vertical view of present embodiment is shown in figure 21, and the label of not explaining again among the figure sees also above relevant explanation.In Figure 21, the 13rd, the charge door of central cooler, to be cooled, red-hot sintering deposit.The 14th, the fan housing on the waste heat recovery section, its angle are θ.The 15th, the part of the airduct of recovery hot blast.
In order to see the section structure of present embodiment clearly, the spy will have the section U-U (rotation, amplification) at fan housing place and not have the section V-V (rotation, amplification) at fan housing place to be plotted in respectively among Figure 22 and Figure 23.
In Figure 22,16,17 is respectively the band that leaks out between fan housing 14 and outer shroud and interior ring 1-1 and the 1-2.Through after the structure optimization, hood configuration 2 and 3 is made up of inner can 2-6 and 3-6, sealing mechanism 2-7 and 3-7 and inside and outside case 2-8 and 3-8 respectively; It should be noted that: inner can 2-8 and outer casing 3-8 also have the function of the slide plate in the sealing mechanism of elastic plate-slide type concurrently, therefore, it is remembered respectively make 2-8 (2-7-2) and 3-8 (3-7-2).Obviously, they formed comprising sealing mechanism 2-7 or 3-7, containing central cooler leak out with 16,17, the sealing hood configuration.Wherein, sealing mechanism 2-7 and 3-7 also are a kind of sealing mechanisms of elastic plate-slide type; According to the result after optimizing; Inner can 2-6 and 3-6 and inner can 2-8 (2-7-2) and outer casing 3-8 (3-7-2) and fan housing 14 and outer shroud and the interior ring 1-1, the last structural member of 1-2 that have the function of the slide plate in the sealing mechanism of elastic plate-slide type concurrently; For example stiffener is one altogether, to obtain best techno-economic effect.
In order to see the details at this place clearly, special partial enlarged drawing with the W place is plotted among Figure 24 and (annotates: because the partial enlarged drawing at the partial enlarged drawing at W1 place and W place is similar, thereby no longer make).From Figure 24, can see clearly, the sealing mechanism 3-7 of elastic plate-slide type is made up of elastic plate 3-7-1, slide plate 3-7-2 (annotating: do by outer casing 3-8 is double), pressing plate 3-7-3 and screw 3-7-4.
It can also be seen that in Figure 24 elastic plate 3-7-1 is made up of steel disc 3-7-1-1 and the steel liner plate 3-7-1-2 of the about 0.3mm of thickness.Connection between steel disc 3-7-1-1 and the steel liner plate 3-7-1-2 can be adopted the method for pressure welding or roll welding; Below steel liner plate 3-7-1-2, also has the surface hardening layer, to improve its wearability and life-span; According to general surface treatment standard, the degree of depth of quench-hardened case can be confirmed according to 2～5mm, simultaneously, does not also repel and adopts other heat-treating methods.
As can be seen from Figure 23, do not having fan housing 14 places, still needed to keep by the double slide plate 3-7-2 that does of outer casing 3-8, the remainder in the hood configuration 3 then no longer keeps.In like manner, therefore inner can 2-8 (2-7-2) also exists, and the remainder in the hood configuration 2 also no longer keeps.
When steel disc 3-7-1-1 (referring to Figure 24) is thin, the ability that its opposing is torn a little less than.Can set up the load carrier of frictional force in case of necessity, to prevent the inefficacy of steel disc 3-7-1-1, shown in figure 25.In Figure 25, pillar 18 is fixed on the steel liner plate 3-7-1-2, the position that keeps steel liner plate 3-7-1-2 through hole on the support 19 and pillar 18, thus to the effect that steel disc 3-7-1-1 plays off-load, make it to avoid to lose efficacy.
Figure 26 is that the X of Figure 25 is to view, so that understand its general configuration; As for the quantity of pillar 18 and support 19, suggestion is provided with once overlapping passable on per 1～3 meter arc length.
What also need explain a bit is that the way of realization steel disc 3-7-1-1 off-load is more, for example, can also adopt brace, drawstring and drag-line etc., has not just given unnecessary details at this.
In addition, present embodiment also has the characteristics that described hood configuration is the part of complete annular, and more particularly, described hood configuration only is the sub-fraction in the complete annular.
It should be noted that in addition: the foregoing description is a case of the present invention, and one of its effect is that the present invention is played explanation, and should not be construed as any restriction that the present invention is made.
