Abstract
The utility model discloses a kind of Induced fan, comprise fan box, in described fan box, install and be separately installed with noise reduction cavity, spiral case, in wherein said noise reduction cavity, hush pipe is installed, in described spiral case, motor is installed, on described motor, impeller is installed, centrifugal backward bent vane is installed on described impeller; On described fan box, nozzle is installed, described nozzle comprises wind pipe, air outlet, and the exhaust outlet diameter of described air outlet is less than the diameter of wind pipe.A kind of Induced fan described in the utility model, it is simple in structure, easy for installation, and pipeline is simple, is convenient to maintenance, and jet direction that can free adjusting nozzle, and power saving, effectively reduce the loss of the energy.
Description
Technical field
The utility model relates to a kind of Induced fan.
Background technique
Traditional ventilation systems in underground car parks all adopts to be installed low speed airduct and send heat-extraction system in storehouse, but adopt this kind of ventilation plant to exist airduct cross-section size larger, gas tends to be collected at the place, dead angle of far filling air draught, the cold height in garage is generally lower, adopt low speed airduct to have constriction, installation workload is large, invests highly, and operating cost is high.
Model utility content
The purpose of this utility model is to provide a kind of Induced fan, and it is simple in structure, easy for installation, and pipeline is simple, is convenient to maintenance, and jet direction that can free adjusting nozzle, and power saving, effectively reduce the loss of the energy.
In order to achieve the above object, the technical solution of the utility model is:
An Induced fan, comprises fan box, in described fan box, installs and is separately installed with noise reduction cavity, spiral case, in wherein said noise reduction cavity, hush pipe is installed, in described spiral case, motor is installed, on described motor, impeller is installed, centrifugal backward bent vane is installed on described impeller; On described fan box, nozzle is installed, described nozzle comprises wind pipe, air outlet, and the exhaust outlet diameter of described air outlet is less than the diameter of wind pipe.
Rubber shock-proof block is installed in described spiral case, on described rubber shock-proof block, motor is installed.
In described fan box, acoustical panel is installed.
Described hush pipe is comprised of super glass wool skin and zinc-plated microwell plate internal layer.
Described fan box is connected with wind pipe by canvas connecting termingal.
The beneficial effects of the utility model are: a kind of Induced fan, and it is simple in structure, easy for installation, and pipeline is simple, is convenient to maintenance, and jet direction that can free adjusting nozzle, and power saving, effectively reduce the loss of the energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of hush pipe in Fig. 1.
Embodiment
Embodiment 1
An Induced fan, comprises fan box 1 as shown in Figure 1, and the interior installation of described fan box 1 is separately installed with noise reduction cavity 2, spiral case 3, in described spiral case 3, rubber shock-proof block 12 is installed, and on described rubber shock-proof block 12, motor 5 is installed.The working life that raising motor 5 is set of rubber shock-proof block 12.On described motor 5, impeller 6 is installed, centrifugal backward bent vane 7 is installed on described impeller 6.The setting of centrifugal backward bent vane 7 can be accelerated air output.On described fan box 1, nozzle 8 is installed, described nozzle 8 comprises wind pipe 9, air outlet 10, and the exhaust outlet diameter of described air outlet 10 is less than the diameter of wind pipe 9.Nozzle 8 can be adjusted and make air draught without dead angle arbitrarily according to actual air-out demand 360 degree.Described fan box 1 is connected with wind pipe 9 by canvas connecting termingal 13.It is vibration isolation that the setting of canvas connecting termingal 13 makes between fan box 1 and wind pipe 9, thereby prevents that airborne impurity from entering blower fan.In described fan box 1, acoustical panel 11 is installed.In described noise reduction cavity 2, hush pipe 4 is installed.Described hush pipe 4 is comprised of super glass wool outer 14 and zinc-plated microwell plate internal layer 15.Being used in conjunction with of acoustical panel 11 and hush pipe 4 improved erasure effect greatly.
A kind of Induced fan of the present embodiment, it is simple in structure, easy for installation, and pipeline is simple, is convenient to maintenance, and jet direction that can free adjusting nozzle, and power saving, effectively reduce the loss of the energy.
