Technical field
The present invention relates to the blower of sintering machine production line, particularly a kind of import flow guide device of sintering machine.
Background technique
SJ series high voltage, efficient centrifugal blower, the main main exhauster being used as smelting industry sintered production line, also can be used for aerodynamic parameter be applicable to other send, be vented place, but conveying medium be not spontaneously inflammable, nontoxic, non-corrosiveness gas, its temperature can not more than 250 DEG C.
Sinter air machine is the key equipment of metallurgy industry raw material sintering, support the use to the sintering machine of relevant specification, the medium of conveying is sinter fume, the advantages such as this serial fan has efficiency high (more than 83%), noise is low, the long service life of rotor, negative pressure are large, adapt to the requirement of modern sintering process raw material layer high negative pressure, improve output and other overall economics index of sintering deposit.
Sintering blower is as the supporting main smoke extractor of sintering machine, its power consumption accounts for greatly more than 1/3rd of the total power consumption of sintering plant, again because the medium of its conveying is sinter fume, dust loading is large, therefore raise the efficiency, reduce energy consumption, strengthen wear-resisting measure, improve working life, be still the major technique problem of sintering centrifugal blower.
The intake grill of current all sintering machines all only plays guide functions, all can directly impact impeller reel when gas flows into impeller, and forms a flex point at this.Sintering machine intake grill and impeller mouth circle belong to Spielpassung, and gap is about about 10mm, and quantity of gas leakage is large.The import flow guide device insertion length of impeller and the gap of impeller mouth circle are directly connected to the quality of fan performance.
Summary of the invention
The object of the present invention is to provide a kind of import flow guide device of sintering machine, this import flow guide device, by improving impeller mouth circle sealing configuration, reduces blower interior gas leakage, improves overall efficiency.By improving air inlet structure, organizing steady air current to enter impeller uniformly, improving impeller internal flow efficiency.In minimizing gas, molecule is to the impact of impeller reel, thus increases the life-span of sintering machine impeller.Its efficiency is higher, and operating cost is lower.
The object of the invention is to be realized by following technical proposals.
A kind of import flow guide device of sintering machine, comprise the guide shell of the tapered layout be connected with suction chamber by flange, guide shell is arranged on the air inlet of impeller casing, described guide shell outer wall is connected with diaphragm seal by sealing ring fixed plate, and diaphragm seal connects with the impeller mouth circle of the impeller sidepiece in impeller casing; Described guide shell connects to holding with impeller casing and is connected to outer shroud and inner ring by gusset.
Further, described sealing ring fixed plate is vertical setting along the conical surface of conical flow guiding cylinder, is connected with several diaphragm seals in the end of sealing ring fixed plate.
Further, described diaphragm seal coordinates with impeller mouth ring gap, and its gap is 1.5 ~ 2mm.
Further, described outer shroud is arranged on outside inner ring, and the ring-side wall of outer shroud is outer broadening formation, and the outer shroud bore of the outer shroud of outer broadening formation is greater than inner ring bore; Described inner ring ring-side wall is the inside trumpet shape of the mouth as one speaks, and the outer shroud bore of the inner ring of the inside trumpet shape of the mouth as one speaks is less than inner ring bore.
Further, described flange is lined with pad.
Further, the intake grill of described impeller casing is identical with the mold joint of suction chamber.
Relative to prior art, the invention has the beneficial effects as follows:
By improving air inlet structure, organizing steady air current to enter impeller uniformly, improving impeller internal flow efficiency; In minimizing gas, molecule is to the impact of impeller reel, thus increases the life-span of sintering machine impeller.By design of Sealing Structure, blower interior gas leakage can be reduced, improve overall efficiency.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation.
In figure: 1, flange, 2, guide shell, 3, inner ring, 4, outer shroud, 5, gusset, 6, impeller casing, 7, pad, 8, diaphragm seal, 9, impeller mouth circle, 10, sealing ring fixed plate.
Embodiment
Below by drawings and Examples, the present invention will be further described.
As shown in Figure 1, the import flow guide device of this sintering machine, comprise the guide shell 2 of the tapered layout be connected with suction chamber by flange 1, guide shell 2 is arranged on the air inlet of impeller casing 6, intake grill and impeller casing 6 adopt jackscrew structure to match, and the intake grill of impeller casing 6 is identical with the mold joint of suction chamber; Flange 1 is lined with pad 7.Wherein, guide shell 2 outer wall is connected with diaphragm seal 8 by sealing ring fixed plate 10, and diaphragm seal 8 connects with the impeller mouth circle 9 of the impeller sidepiece in impeller casing 6; Guide shell 2 connects with impeller casing 6 to holding and is connected to outer shroud 4 and inner ring 3 by gusset 5.
Wherein, sealing ring fixed plate 10 is vertical setting along the conical surface of conical flow guiding cylinder 2, is connected with several diaphragm seals 8 in the end of sealing ring fixed plate 10, and diaphragm seal 8 and impeller mouth enclose 9 Spielpassung, and its gap is 1.5 ~ 2mm.
This device, according to fan inlet flow pattern, in conjunction with the feature having solid particle in sinter fume, devises the molded line of inner ring 3, outer shroud 4, to reduce in air-flow solid particle to the impact of impeller.Viewed from blower fan meridian plane, the molded line of inner ring 3, outer shroud 4 is streamlined; Distribute ringwise along blower fan axle center circumference.Its structure is that gusset 5 is connected on the nozzle wallboard of guide shell 2, and outer shroud 4 is arranged on outside inner ring 3, and the ring-side wall of outer shroud 4 is outer broadening formation, and the outer shroud bore of outer broadening formation is greater than inner ring bore; Inner ring 3 ring-side wall is the inside trumpet shape of the mouth as one speaks, and the outer shroud bore of the inside trumpet shape of the mouth as one speaks is less than inner ring bore.Outer shroud 4 and guide shell 2 play good water conservancy diversion and shunting action, by improving intake grill flow field structure, reducing eddy current loss, organizing steady air current to enter impeller uniformly, improve impeller internal flow efficiency.
This device also devises the sealing of Sinter air machine mouth circle, encloses 9 Spielpassung, make gas leakage amount drop to so minimum by sealing ring fixed plate 10, diaphragm seal 8 with the impeller mouth of blower fan.Thus blower interior gas leakage can be reduced, improve overall efficiency.
Above-described embodiment gives a narrow example to invention has been detailed description; can not assert that embodiments of the present invention are only limitted to this; for general technical staff of the technical field of the invention; all any simple modification of doing according to Spirit Essence of the present invention and equivalent structure transformation or modification, all belong to the protection domain that claims that the present invention submits to are determined.
