Description
Technical field
Laboratory services technical field is the utility model is related to, more particularly to it is a kind of in line for laboratory hood
The double dynamical anti-corrosion blower fan of double-core of wind.
Background technology
When carrying out producing the experiment of toxic harmful exhaust gas and acid mist in laboratory, it usually needs can air draft vent cabinet
Operated in (exhaust fume hood), the quality of ventilation effect, except the structure with vent cabinet has outside the Pass, main and air draft blower fan is close
It is related.At present, the mode of air draft mainly has two kinds.One kind is outer (being generally arranged at roof) the drawing and pulling type air draft of cabinet, suitable for useless
Large-minded, air draft is apart from remote situation.Advantage is that fan pressure air quantity is big；Shortcoming is that blower fan volume is big, and power consumption is big, and noise is big.
So to supply and exhaust apart from situation short, that assembling is limited by field condition again, also frequently with built-in exhaust blower.Due to being
Blower fan is directly installed in vent cabinet (top), so the volume of blower fan is required, situation of the load-bearing in vent cabinet conditions permit
Under, its air quantity, noise must be able to meet requirement.Existing market is using monokaryon (motor) centrifugal blower, to make great efforts to increase
Add power and rotating speed to be that power consumption and noise are consequently increased the shortcomings that meeting the requirement of air quantity, but cause.
The content of the invention
The utility model is that exhaust fan air quantity in laboratory is small can not to meet that requirement or air quantity are made an uproar greatly in order to solve
The problem of sound is also big, there is provided it is a kind of that enough airflow pressures can be provided, leading to for laboratory for excessive noise will not be produced again
The double dynamical anti-corrosion blower fan of double-core of the in line wind of wind cabinet.
To achieve these goals, the utility model uses following technical scheme, and it is in line that one kind is used for laboratory hood
The double dynamical anti-corrosion blower fan of double-core of wind, including Blower Housing, described Blower Housing are cuboid-type, inside the Blower Housing
Both ends are respectively equipped with a centrifugal blower, and described Blower Housing bottom is respectively equipped with the air inlet coordinated with centrifugal blower, institute
State and be provided with an air outlet at the top of Blower Housing, described air outlet is provided with trumpet type water conservancy diversion interface, described water conservancy diversion interface
Bore and the matching of outer air duct external diameter in upper end, the water conservancy diversion interface lower end is cubic trumpet type, is also set in the Blower Housing
Someone's shape guide-flow-board, the exhaust outlet of described centrifugal blower pass through herringbone deflector and water conservancy diversion orifice.
Preferably, described centrifugal blower is anti-corrosion centrifugal impeller blower fan.
Preferably, described air inlet is provided with baffle liner.
This programme is according to aerodynamic principle, by the structure of two sets of low power consumption electric motors and multiple wing impeller combination vent cabinet,
A set of centrifugation exhaust system is combined into, overcomes monokaryon single impeller blower fan blast under the same conditions, the shortcomings that air quantity is small, is being protected
The blast and air quantity that blower fan air draft is improved in the state of low-power consumption low noise are held.
Therefore, the utility model has the advantages that：(1) enough airflow pressures can be provided；(2) will not produce
Big noise.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is Fig. 1 top view.
Fig. 3 is Fig. 1 A-A sectional views.
In figure：1st, Blower Housing 2, centrifugal blower 3, air inlet 4, air outlet 5, water conservancy diversion interface 6, herringbone
Deflector 7, baffle liner.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of double dynamical anti-corrosion blower fan of double-core for the in line wind of laboratory hood, including
Blower Housing 1, Blower Housing 1 are cuboid-type, and the inside both ends of Blower Housing 1 are respectively equipped with a centrifugal blower 2, Blower Housing
1 bottom is respectively equipped with the air inlet 3 coordinated with centrifugal blower 2, and the top of Blower Housing 1 is provided with an air outlet 4, on air outlet 4
Provided with trumpet type water conservancy diversion interface 5, bore and the matching of outer air duct external diameter, the lower end of water conservancy diversion interface 5 are four directions in the upper end of water conservancy diversion interface 5
Trumpet type, is additionally provided with herringbone deflector 6 in Blower Housing 1, and the exhaust outlet of centrifugal blower 2 is by herringbone deflector 6 with leading
Stream interface 5 connects；
Centrifugal blower 2 is anti-corrosion centrifugal impeller blower fan；Air inlet 3 is provided with baffle liner 7.
Specifically used process is that Blower Housing 1 or so respectively sets the motor and centrifugal blower 2 of a set of small size low-power, face
Two independent air intake mouths 3 of installation, air inlet 3 set baffle liner 7 in opposite directions on opposite；Two centrifugal blowers 2 share an air outlet 4, go out
Chevron shaped deflector 6 is set among air port 4, reduces windage, by two sets relatively independent outlet system of air synthesize it is unidirectional go out
Air port 6；
This programme is combined into a set of exhaust system using two low-power motors and impeller, increases the direct blower fan of vent cabinet
The blast and air quantity of system, there is higher practical value and economic benefit.
