Abstract
The utility model provides a large -traffic fire protection and smoke exhaust fan of bilobed wheel mainly stretches motor, fan casing, flow distribution plate, diversion separator plate, impeller assembly II by impeller assembly I, biax and constitutes, its characterized in that fan casing is equipped with a fan import and two fan exports, inside flow distribution plate and the diversion separator plate of setting up of fan casing, impeller assembly I and impeller assembly II install respectively that to stretch motor shaft at the biax epaxial, and the biax is stretched the motor and is installed inside the fan casing. The utility model relates to a noise is low, the reliability is high, compact structure's large -traffic fire protection and smoke exhaust fan of bilobed wheel.
Description
Technical field
The utility model belongs to the aeration technology fields such as subway, tunnel, civilian fire-fighting access, is specially adapted in the confined space, promote that flow of flue gas is evacuated, and ensures a kind of bilobed wheel large discharge smoke exhaust fan of personal security in closed area fast.
Background technique
Along with the fast development of national economy, urban construction and flow of personnel are tending towards maximizing and densification.For alleviating the space pressure brought thus, public domain and the underground space turn the new theme of urban planning into.And because flow of personnel amount is large, spatial structure is compact, gateway is few in these regions, cause sluggish in air circulation, particularly produced when a fire flue gas concentration is large, strong toxicity, as evacuated not in time, in region personnel this high temperature poisonous and in the environment of severe depletion of oxygen the moment have the danger suffocated.Therefore, large discharge smoke exhaust fan must be relied on to carry out the mandatory evacuation of flue gas.But in a limited space, because being subject to arranging that the restriction in place cannot install the smoke exhaust fan of large plane No., and the rotating speed of draught fan impeller cannot improve because being subject to the constraints such as impeller material, fan efficiency and ambient noise requirement.So when the device space is increasingly compact, there is the shortcomings such as underfed, noise are large, poor reliability in single impeller smoke exhaust fan.
Model utility content
The utility model is intended to overcome above-mentioned defect, and object is to provide that a kind of noise is low, reliability is high, the bilobed wheel large discharge smoke exhaust fan of compact structure.
For achieving the above object, the technical solution adopted in the utility model is that complete machine forms by by impeller sets I, motor for double-ended drive, Blower Housing, flow distribution plate, diaphragm, impeller sets II; Its Blower Housing is provided with a fan inlet and two fan outlets; Blower Housing inside arranges flow distribution plate and diaphragm; Impeller sets I and impeller sets II are arranged on the front and back outer shaft of motor for double-ended drive rotating shaft respectively, and motor for double-ended drive is installed on Blower Housing inside.
Owing to adopting technique scheme, the utility model smoke exhaust fan, air-flow is shunted through flow distribution plate first and after diaphragm water conservancy diversion, is entered two ends impeller sets respectively and form high velocity air discharge.Compared with the common smoke exhaust fan of existing single impeller, under identical impeller diameter and wheel speed situation, the utility model possesses larger flue gas flow and the smoke exhaust efficiency of Geng Gao; In identical compressor flow situation, the utility model has that plane No. is little, noise is low, the advantage of compact structure.
Accompanying drawing explanation
Fig. 1 is a kind of bilobed wheel large discharge of the utility model smoke exhaust fan structural representation;
In the drawings: 1 is impeller sets I; 2 is Blower Housing; 3 is flow distribution plate; 4 is diaphragm; 5 is motor for double-ended drive; 6 is impeller sets II.
Embodiment
Below in conjunction with accompanying drawing, explanation is described further to the utility model.
The utility model forms primarily of impeller sets I (1), motor for double-ended drive (5), Blower Housing (2), flow distribution plate (3), diaphragm (4), impeller sets II (6); Its Blower Housing (2) is provided with a fan inlet and two fan outlets; Blower Housing (2) inside arranges flow distribution plate (3) and diaphragm (4); Impeller sets I (1) and impeller sets II (6) are arranged on the front and back outer shaft of motor for double-ended drive (5) rotating shaft respectively, and it is inner that motor for double-ended drive (5) is installed on Blower Housing (2).Blower Housing (2) arranges a streamlined fan inlet, and cylindrical shell two ends are set to two contrary fan outlets of direction.Arrange flow distribution plate (3) in fan inlet inside, arrange diaphragm (4) at cylinder body bottom, diaphragm (4) is made up of two sections of arc sections, and the convex surface of two sections of arc sections is opposing, forms the diversion space of hollow seal with Blower Housing (2).The impeller sets I (1) be arranged on the front and back outer shaft of motor for double-ended drive (5) rotating shaft is wing blades with impeller sets II (6) blade, and established angle is identical, prevents 2 grades of impellers from occurring the phenomenon that tacks.
The utility model smoke exhaust fan, first forms two strands of uniform air flows through flow distribution plate (3), then enters Blower Housing (2) inner after diaphragm (4) water conservancy diversion, and air-flow steadily leads two ends impeller sets.It is inner that motor for double-ended drive (5) is positioned at Blower Housing (2), and be in it on same axis.Under the driving of motor for double-ended drive (5), the two ends impeller sets that rotation direction is contrary is done work to flue gas respectively, becomes high velocity air and discharges from two ends fan outlet.Arrange flow distribution plate (3), the function of diaphragm (4) is change blower interior air motion direction, the uniform stream that guarantee flows to blower fan two ends is steady, avoids the impeller acting of blower fan two ends mutually to disturb, reduces the pneumatic noise of blower fan.Impeller sets I (1) and impeller sets II (6) are respectively to the acting of two ends flue gas, and by energy transferring to air-flow, ensure that flue gas discharges blower fan with high pressure energy, bilobed wheel acting simultaneously can reduce blower fan boundary dimension, ensures compact structure.
Therefore, the utility model is that a kind of noise is low, reliability is high, the bilobed wheel large discharge smoke exhaust fan of compact structure.
Claims (1)
1. a bilobed wheel large discharge smoke exhaust fan, forms primarily of impeller sets I (1), motor for double-ended drive (5), Blower Housing (2), flow distribution plate (3), diaphragm (4), impeller sets II (6); It is characterized in that Blower Housing (2) is provided with a fan inlet and two fan outlets; Blower Housing (2) inside arranges flow distribution plate (3) and diaphragm (4); Impeller sets I (1) and impeller sets II (6) are arranged on the front and back outer shaft of motor for double-ended drive (5) rotating shaft respectively, and it is inner that motor for double-ended drive (5) is installed on Blower Housing (2).
