Description
Technical field
This utility model belongs to field of ventilation equipment, especially relates to a kind of induction fan.
Background technology
In society now, owing to private vehicle gets more and more, cause blocking up of city very serious, this
Sample allows for relevant departments carrying out safeguarding the pipe networks such as electrical network, coal gas and water and communication when, can cause
Traffic congestion inconvenience.And country also becomes more ripe for design and the layout of pipe network now, and now
The developing direction of country is to set up underground pipe gallery integrated system.Electricity, gas and water, confession are warmed up by this system
The pipe network such as communication is unified to be arranged, it all is put in same underground pipe gallery.Such design allows for leading to
Blower fan needs have joint space-efficient function, and then ensures overall piping lane ventilation smoothness.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of induction fan, under being particluarly suitable for mixedly
Piping lane entirety is aerated ventilation by piping lane.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of induction fan, including housing and fan main body, described induction fan is outside is housing,
Fan main body lateral symmetry is provided with lifting plate, is provided with some deflectors, institute inside described induction fan
Stating and be provided with motor in the middle part of deflector, the outfan of described motor is provided with impeller, and wheel nose arranges and leads
Stream cap, the inwall of described induction fan is provided with noise elimination orifice plate, the outer wall of described induction fan sets
Having blower fan clad, described induction fan air intake and outlet air end are provided with nozzle, outside described nozzle
Portion is provided with protection network.
Described induction fan selection is corrosion-resistant metal materials.
Described nozzle generally circular in shape.
Described nozzle throat area is equal diameter structure.
Described nozzle throat area is variable diameters structure.
Being shaped as of described nozzle is square.
Fan main body can be centrifugal, axial-flow type or diagonal flow type.
In described clad, noise elimination cotton is set.
In use, blower fan clad is wrapped on induction fan outer wall, has certain noise elimination
Effect, nozzle can carry out 360 degree of layouts around centrage, and can just run by inverted ventilation.Induced draught
Machine can be one one group or multiple stage one group, and induction fan can be centrifugal, axial-flow type or oblique flow
Formula.
This utility model has the advantage that with good effect: owing to using technique scheme so that lure
Conducting blower fan becomes convenient and effective to the ventilation that underground pipe gallery is overall, is ensureing ventilation effect
On the premise of, it is greatly saved induction fan space hold in underground pipe gallery, is suitable for integrally
The ventilation work of lower piping lane system, blower fan integral coating and noise elimination orifice plate effectively reduce noise；And this
Utility model has simple in construction, easy to maintenance, and processing cost is low, work efficiency advantages of higher.

Wall is provided with noise elimination orifice plate 7, and the outer wall of described induction fan is provided with blower fan clad 6, described in lure
Conducting blower fan air intake and outlet air end are provided with nozzle 2, and described nozzle 2 is outside is provided with protection network 8.
Induction fan selection is corrosion-resistant metal materials.Nozzle 2 generally circular in shape or square.Nozzle 2 is horizontal
Cross section is equal diameter structure or variable diameters structure.In described clad 6, noise elimination cotton 9 is set.
In use, blower fan clad 6 is wrapped on induction fan outer wall, plays certain disappearing
Sound effect, nozzle 2 can carry out 360 degree of layouts around centrage, and can just run by inverted ventilation.Induction
Ventilation blower can be one one group or multiple stage one group, and induction fan can be centrifugal, axial-flow type or
Diagonal flow type.
Above an embodiment of the present utility model is described in detail, but described content has been only this reality
With novel preferred embodiment, it is impossible to be considered for limiting practical range of the present utility model.Fan Yiben
Impartial change that utility model application scope is made and improvement etc., all should still belong to of the present utility model specially
Within profit covering scope.
