Description
Technical field
The utility model relates to a kind of ventilation equipment class technical field, especially a kind of centrifugal blower pressurization outlet air interface.
Background technique
The ventilation of tunnel class generally uses centrifugal blower 1001, since to be generally Section Space smaller but more deep in tunnel
Long, the centrifugal blower for continuing working ventilation mainly needs far firing range of divulging information, and ventilation range is remoter, and the ventilation effect in tunnel is just imitated
Rate is high, also results in that powerful centrifugal blower is needed to generate the higher air quantity of wind pressure to meet the requirement of ventilation far firing range, but
It is that centrifugal blower power is bigger, and volume is also bigger, the air outlet of centrifugal blower also increases accordingly, permanent in centrifugal blower power
In the case where fixed, the wind pressure of submitting is also constant, while range of divulging information is also just constant, and tunnel because space it is small, also tending to cannot
The powerful centrifugal blower of large volume is laid, and centrifugal blower needs the operation that around the clock works, energy consumption cost is also just very
Height, for this reason, it may be necessary to a kind of simple and centrifugal blower pressurization conventionally exhaust apparatus.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of centrifugal blower pressurization outlet air is provided and is connect
Mouth, including outlet air interface body, outlet air interface body set pressurization taper square tube, and the air inlet end of pressurization taper square tube sets socket
Mouthful, the periphery of socket is all provided with several connecting holes, and the bore for the taper square tube right end air outlet that pressurizes is scaled, this is practical new
The socket of the outlet air interface body of type be socketed in the air outlet of centrifugal blower and with connecting screw outlet air interface body with from
The air outlet of heart blower is fixed, and the air quantity that centrifugal blower is sent out enters after pressurization taper square tube by setting in pressurization taper square tube
Bore reduces ratio and is gradually compressed, and bores after air quantity is gradually compressed while also synchronization is gradually pressurized from small-bore pressurization
The air outlet of shape square tube right end is sent out, and the range of discharge quantity of fan is greatly improved in the state of centrifugal blower power and constant air quantity
Also wind pressure, structure is simple, at low cost, practical.
In order to achieve the above objectives, the utility model provides a kind of centrifugal blower pressurization outlet air interface, including outlet air interface sheet
Body, the outlet air interface body set pressurization taper square tube, and the air inlet end of the pressurization taper square tube sets socket, the socket
The periphery of mouth is all provided with several connecting holes.
The bore of the air inlet is greater than the air outlet bore of right end.
The beneficial effects of the utility model are: the socket of the outlet air interface body of the utility model is socketed in centrifugal blower
Air outlet and the air outlet of outlet air interface body and centrifugal blower is fixed with connecting screw, centrifugal blower send out air quantity into
Enter to pressurize and reduce ratio in the bore set in pressurization taper square tube after taper square tube and gradually compressed, air quantity is gradually compressed
Simultaneously also it is synchronous be gradually pressurized after sent out from the air outlet of small-bore pressurization taper square tube right end, in centrifugal blower power and
The range of discharge quantity of fan also wind pressure is greatly improved in the state that air quantity is constant, structure is simple, and it is at low cost, it is practical.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model,
Fig. 2 is the application connection schematic diagram of Fig. 1.
In figure: outlet air interface body 1, pressurization taper square tube 2, socket 3, connecting hole 4, air inlet 5, air outlet 6, centrifugation
Blower 1001, connecting screw 1002.
Specific embodiment
As shown in FIG. 1 to FIG. 2: the technical solutions of the present invention will be further described, a kind of centrifugal blower
Pressurize outlet air interface, including outlet air interface body 1, and the outlet air interface body 1 sets pressurization taper square tube 2, the pressurization taper
5 end of air inlet of square tube 2 sets socket 3, and the periphery of the socket 3 is all provided with several connecting holes 4, and the outlet air of the utility model connects
The socket 3 of mouthful ontology 1 be socketed in the air outlet of centrifugal blower 1001 and with connecting screw 1002 outlet air interface body 1 and from
The air outlet of heart blower 1001 is fixed, and the air quantity that centrifugal blower 1001 is sent out enters after pressurization taper square tube 2 by pressurization taper side
The bore reduced scale set in pipe 2 is gradually compressed, air quantity it is gradually compressed and meanwhile also it is synchronous be gradually pressurized after from
The air outlet 6 of small-bore pressurization 2 right end of taper square tube is sent out, big in the state of 1001 power of centrifugal blower and constant air quantity
The big range for improving discharge quantity of fan also wind pressure, structure is simple, at low cost, practical.
Greater than 6 bore of air outlet of right end, energy air quantity is synchronous while conveying to be added the bore of the air inlet 5 by compression
Pressure increases ventilation range.
In practical application, the air inlet 5 for taper square tube 2 of pressurizeing and the bore ratio of air outlet 6 can be by application environment demands
And different specifications being set, and install and use by the ventilation requirement of actual environment, the shape of air outlet 6 can install air inlet 5
Shape it is scaled, air outlet 6 can be also arranged to according to practical application request different shapes, such as round, flat.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
