Abstract
The utility model provides a change centrifugal fan of air inlet direction, includes the shell and is fixed in spiral case centrifugal fan in the shell, the shell is case form, its with the side of spiral case centrifugal fan's first air outlet homonymy has a second air outlet, this second air outlet with first air outlet is connected, and this shell with side outside spiral case centrifugal fan's the first air intake homonymy side has the second air intake. The utility model discloses simple structure, make conveniently, through the design of shell, has changed the air inlet orientation of fan, make the fan can be from the orientation air inlet beyond the spiral case centrifugal fan air inlet orientation, overcome traditional centrifugal fan since the mounted position or with other equipment cooperations on the restriction, problem that can't the air inlet has satisfied user's demand.
Description
Technical field
The utility model is related to centrifugal blower field, more particularly, to a kind of centrifugal blower changing air intake direction.
Background technology
Centrifugal blower is the mechanical energy relying on input, improves gas pressure and supplies gas side by side the machinery of body, and gas is from axially entering
Enter draught fan impeller, and be radially redirected through impeller, it is a kind of driven fluid machinery.Centrifugal blower is widely used in factory, ore deposit
The ventilation of well, tunnel, cooling tower, vehicle, ship and building, dust discharge and cooling；The ventilation of boiler and industrial furnace and air inducing；
Cooling in the apparatus of air conditioning and domestic electric appliance and ventilation；The drying of cereal and selecting and recommending；Wind-tunnel wind regime and aircushion vehicle
Inflation and propulsion etc..
Traditional centrifugal blower is usually volute casing centrifugal blower fan, and its air intake and air-out direction are fixing, but, in reality
During border uses, often produce the restriction coordinate due to installation site or with other equipment, and can not be from air intake side
To the problem of air intake, thus the demand of user cannot be met.
Utility model content
Based on this, for above-mentioned technical problem, provide a kind of centrifugal blower.
For solving above-mentioned technical problem, the utility model adopts the following technical scheme that：
A kind of change air intake direction centrifugal blower, include shell and be fixed on described inside the shell spiral case be centrifuged wind
Machine, described shell is in box like, and it has the second air outlet in the side of the first air outlet homonymy with described volute casing centrifugal blower fan,
This second air outlet is connected with described first air outlet, and this shell is in the first air inlet homonymy with described volute casing centrifugal blower fan
Side outside side has the second air inlet.
Described second air inlet is located at the leading flank of described shell, and described second air outlet is located at the rear side of described shell
Face.
Described inside the shell has the fix bar lateralling secure described volute casing centrifugal blower fan.
Described fix bar is vertically arranged.
The utility model structure is simple, easily manufactured, by the design of shell, changes the air intake direction of blower fan, makes wind
Direction air intake beyond volute casing centrifugal blower fan air intake direction for the function, overcome conventional centrifugal blower fan due to installation site or with
Restriction in other equipment cooperation, it is impossible to the problem of air intake, meets the demand of user.
Brief description
The utility model is described in detail with reference to the accompanying drawings and detailed description：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of rear side of the present utility model.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of centrifugal blower changing air intake direction, including shell 110 and be fixed on shell
Volute casing centrifugal blower fan 120 in 110.
Shell 110 is in box like, and it has second in the side of the first air outlet 121 homonymy with volute casing centrifugal blower fan 120
Air outlet 111, this second air outlet 111 is connected with the first air outlet 121, and this shell 110 with volute casing centrifugal blower fan 120
Side outside first air inlet 122 face has the second air inlet 112.
The utility model passes through the design of shell 110, changes air intake direction, enables blower fan from volute casing centrifugal blower fan 120
Air intake direction beyond direction air intake, overcome conventional centrifugal blower fan due to installation site or with other equipment cooperation on
Limit it is impossible to the problem of air intake, meet the demand of user.
Specifically, the second air inlet 112 is located at the leading flank of shell 110, after the second air outlet 111 is located at shell 110
Side, makes the air intake of centrifugal blower and air-out direction be in 180 °.
In order to fix volute casing centrifugal blower fan 120, there is in shell 110 fix bar lateralling secure volute casing centrifugal blower fan 120
113, fix bar 113 is vertically arranged naturally it is also possible to be arranged in other directions.
But, those of ordinary skill in the art is it should be appreciated that above embodiment is intended merely to explanation originally
Utility model, and be not used as being to restriction of the present utility model, as long as in spirit of the present utility model, to
The change of upper described embodiment, modification all will fall in Claims scope of the present utility model.
