Abstract
Axial-flow type smoke exhaust fan, mainly it is made up of housing, some blades, middle cylinder, motor and wheel hub, motor is fixed on inside middle cylinder, the output shaft of motor is connected with wheel hub, blade is arranged on hub surface, and each blade arranges arc windward side, arranges stator between housing and middle cylinder, the connection box for motor of motor passes middle cylinder and housing, and the rear end wind outlet of motor arranges tail wheel.This utility model adopts axial-flow type air guide structure, the tail wheel of motor rear end is combined using the arc windward side of blade, smoke evacuation wind-guiding, working stability can be stably carried out, fan operation noise is greatly reduced, has the advantages that reasonable in design, stable and ventilation efficiency is high.
Description
Technical field
This utility model is related to blower fan technical field, and in particular to a kind of axial-flow type smoke exhaust fan.
Background technology
With the development of building industry, the fire safety problem of building becomes more and more important.In recent years the modern architecture for building up generally is arranged
Fire-fighting smoke exhaust system, system are mainly made up of several parts such as induction installation, control device, smoke duct and smoke exhaust fan.
Smoke exhaust fan is the core component of fire-fighting smoke exhaust system, develops high performance smoke exhaust fan and will produce good Jing
Ji benefit and social benefit.At present, domestic general smoke exhaust fan adopts interior separate ventilation double-decker, inner core to undertake motor
Radiating and tissue hyperthermia flue gas conduct heat to motor, and outer tube undertakes the conveying of high-temperature flue gas.Inner core arranges circulation impeller, quotes pipeline
To electric motor temperature reduction, extraneous air ensures that blower fan is normally run at high temperature.Such blower fan is due to Heat-dissipating impeller of motor power consumption
With generation noise, increase blower fan entirety energy consumption increase, noise, effectively utilizes power is reduced.
Utility model content
This utility model provides a kind of axial-flow type smoke exhaust fan, so that the noise for solving prior art presence is big, energy
Consumption height and the low problem of classification efficiency.
This utility model solves the technical scheme adopted by its technical problem：
A kind of axial-flow type smoke exhaust fan, is mainly made up of housing, some blades, middle cylinder, motor and wheel hub, and motor is solid
It is scheduled on inside cylinder, the output shaft of motor is connected with wheel hub, blade is arranged on hub surface, each blade arranges arc windward
Face, arranges stator between housing and middle cylinder, the connection box for motor of motor passes middle cylinder and housing, and the rear end wind outlet of motor is arranged
Tail wheel.
Above-mentioned housing rear and front end is respectively provided with an adpting flange.
Above-mentioned housing bottom arranges some lower margins.
Operation principle of the present utility model is that the blade installed on motor and wheel hub is coaxially connected, and blade is under motor drive
Gas medium Jing arcs windward side inspiration is gone, wind is discharged inside cylinder and then at the tail wheel of middle tube rear end in.
This utility model adopts axial-flow type air guide structure, combines the tail wheel of motor rear end using the arc windward side of blade,
Smoke evacuation wind-guiding can stably be carried out, working stability greatly reduces fan operation noise, with reasonable in design, stable and
The high advantage of ventilation efficiency.
Description of the drawings
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is schematic elevation view of the present utility model.
1 housing in figure, 2 adpting flanges, 3 blades, 4 motors, 5 lower margins, 6 stators, 7 connection box for motor, cylinder in 8,9 wheel hubs,
10 tail wheels.
Specific embodiment
As depicted in figs. 1 and 2, a kind of axial-flow type smoke exhaust fan, mainly by housing 1, some blades 3, middle cylinder 8, electricity
Machine 4 and wheel hub 9 are constituted, and motor 4 is fixed on inside middle cylinder 8, and the output shaft of motor 4 is connected with wheel hub 9, and blade 3 is arranged on wheel hub 9
Surface, each blade arrange arc windward side, and stator 6 is arranged between housing 1 and middle cylinder 8, and the connection box for motor 7 of motor 4 is passed
Middle cylinder 8 and housing 1, the rear end wind outlet of motor 4 arrange tail wheel 10, and 1 rear and front end of housing is respectively provided with an adpting flange 2,
1 bottom of housing arranges some lower margins 5.
Operation principle of the present utility model is that the blade installed on motor and wheel hub is coaxially connected, and blade is under motor drive
Gas medium Jing arcs windward side inspiration is gone, wind is discharged inside cylinder and then at the tail wheel of middle tube rear end in.
This utility model adopts axial-flow type air guide structure, combines the tail wheel of motor rear end using the arc windward side of blade,
Smoke evacuation wind-guiding can stably be carried out, working stability greatly reduces fan operation noise, with reasonable in design, stable and
The high advantage of ventilation efficiency.
