Description
[technical field]
The present invention relates to purification technology field more particularly to a kind of smoke exhaust ventilators equipped with diagonal flow fan.
[background technique]
Due to Chinese food culture feature, people can generally generate a large amount of oil smoke during kitchen makes food,
The oil smoke of generation, which not only influences kitchen environment, can also generate biggish harm to kitchen operation personnel.In order to purify kitchen
Environment, people devise can be by the smoke exhaust ventilator outside oil smoke discharge to kitchen.
The air intake device of smoke exhaust ventilator is generally multiple wing type centrifugal ventilation blower at present, and structure mainly includes Multivane impeller
And spiral case.Using this form blower the main reason for are as follows: Multivane impeller manufacturing cost is low, discharge coefficient and pressure coefficient
It is all bigger, and noise is small, shortcoming is that Multivane impeller efficiency is relatively low.In addition, flue gas passes through in European smoke exhaust ventilator
After panel is upwardly into fume exhaust fan box, it is also necessary to which turning 90 ° can enter fans entrance just to be discharged.This design causes
For mobile phase of the air-flow in smoke exhaust ventilator to disorder, smoke exhaust ventilator overall efficiency is relatively low.
Diagonal flow fan had not only done centrifugal movement by air but also had axially moved, and coefficient of wind pres is higher than axial flow blower, flow system
Number is bigger than centrifugal blower, while operating condition area is broad.Replace the centrifugal fan in present smoke exhaust ventilator can be with diagonal flow fan
The flow of smoke exhaust ventilator is promoted, and improves the flow passage structure inside fume exhaust fan box, to greatly promote smoke exhaust ventilator work
Make efficiency.
[summary of the invention]
It is an object of the invention to replace existing multiple wing type centrifugal blower fan using novel diagonal flow fan structure type, with
Promote the efficiency of smoke exhaust ventilator, flow and wind pressure.
By the content of present invention, details are as follows below:
A kind of smoke exhaust ventilator equipped with diagonal flow fan of the present invention, including diagonal flow fan and the big portion of fume exhaust fan box two
Point.
Diagonal flow fan mainly include outer housing, inner tube, impeller, motor, guide vane it is characterized by:
The outer housing is hollow rotary body, and front end forms open air inlet, rear end forms open gas outlet；
Said inner tube is hollow rotary body, described by being fixed on around the equally distributed number of guide vanes of its lateral surface
The inner wall of outer housing, motor are fixed in inner tube by supporting element, drive rotary shaft, the front end connection of rotary shaft by motor shaft
Impeller, the impeller is by truncated cone-shaped wheel hub and is surrounded on the equally distributed blade of multi-disc of wheel hub side and constitutes；
Said inner tube, rotary shaft, front hub central axes be overlapped with outer housing central axes；
Wherein, the impeller is designed using three-dimensional flow method, and blade is twisted blade, from blade inlet edge to trailing edge edge
Wheel hub surface is in twist distribution.
Wherein, the impeller uses big and small blade structure, and big blade, vanelets are uniformly at intervals on wheel hub.
Wherein, the guide vane is bending rectangle, is uniformly distributed around inner tube；
Wherein, the guide vane number is 40 degree of inlet angle, 0 degree of the angle of outlet between 15 to 30.
Fume exhaust fan box of the invention is identical as most of European fume exhaust fan box, diagonal flow fan shell and smoke pumping
It is connected inside box body and fixed.
A kind of smoke exhaust ventilator equipped with diagonal flow fan of the present invention, advantage and effect are: the cabinet of smoke exhaust ventilator is not
Need to do too many change, and the setting of diagonal flow fan, diagonal flow type wind can be directly entered by the flue gas of cabinet import upwards
Machine import, air-flow can obtain higher pressure and rise and be discharged without biggish turning.Such design takes full advantage of pumping
The space of oil smoke box body and the path for optimizing air-flow improve efficiency, flow and the wind pressure of smoke exhaust ventilator.

[specific embodiment]
With reference to the accompanying drawing, technical scheme is described further.
It is the structural schematic diagram of the European smoke exhaust ventilator of tradition such as Fig. 1 (a) and Fig. 1 (b), air-flow passes through 2 body of smoke pumping cabinet
Into centrifugal blower 1, this can make air-flow turn by force 90 ° or so, seriously affect smoke exhaust ventilator efficiency.
It is the structural schematic diagram of novel diagonal flow type smoke exhaust ventilator, diagonal flow fan 3 and centrifugation wind such as Fig. 2 (a) and Fig. 2 (b)
Machine is equally mounted in fume exhaust fan box 2, and the cabinet of smoke exhaust ventilator does not need to do too many change.And the advantage of diagonal flow fan
It is, diagonal flow fan import can be directly entered by the flue gas of cabinet import upwards, air-flow is without biggish turning, just
Higher pressure can be obtained to rise and be discharged.It is such to design the space for taking full advantage of fume exhaust fan box and optimize air-flow
Path, improve the efficiency and flow of smoke exhaust ventilator.
It is diagonal flow fan vertical section schematic diagram such as Fig. 3, diagonal flow fan mainly includes outer housing 10, impeller 20, inner casing
Body 30, guide vane 40, motor 50；
The outer housing 10 is hollow rotary body, and front end forms open air inlet 101, rear end forms open gas outlet
102；
Said inner tube 30 is hollow rotary body, by being fixed on institute around its equally distributed number of guide vanes 40 in outside
The inner wall of outer housing 10 is stated, motor 50 is fixed in inner tube 30 by supporting element 501, passes through motor driven rotary shaft 502, rotation
Axis is connected with impeller 20；
It is the stereoscopic schematic diagram of impeller 20 such as Fig. 4, which is designed using three-dimensional flow method, effectively raises impeller
Efficiency；Impeller uses big and small blade structure, big blade 201, and vanelets 202 on wheel hub 203, can increase so uniformly at intervals
Add the area of impeller inlet, reduces flowing blocking.Flowing blocking can equally be reduced.
It is 40 schematic diagram of guide vane such as Fig. 5, guide vane is bending rectangle, around the uniformly distribution of inner tube 30, according to reality
Border situation guide vane number can be 40 degree of inlet angle, 0 degree of the angle of outlet between 15 to 30 with value range.
