Description
Technical field
The utility model relates to a kind of improved centrifugal blower, belongs to ventilating machinary.
Background technique
Centrifugal blower comprises spiral case, external rotor electric machine and impeller, and impeller places in the spiral case and with external rotor electric machine and is connected, and external rotor electric machine is fixed on the spiral case by support, and the axle head of impeller is provided with intake grill, and spiral case is provided with exhaust outlet.Centrifugal blower has obtained using widely as important ventilation equipment, and existing centrifugal blower boundary dimension is bigger, the fabricating cost height, and have only an exhaust outlet, can only realize unidirectional air-supply, when the two-way air-supply of needs, pipeline is made comparatively complicated, uses extremely inconvenient.
The model utility content
The purpose of this utility model is to provide a kind of double-vent centrifugal aerator, and boundary dimension is little, and fabricating cost is low, and can realize two-way air-supply easily.
Double-vent centrifugal aerator described in the utility model, spiral case, external rotor electric machine and impeller are arranged, impeller places in the spiral case and with external rotor electric machine and is connected, external rotor electric machine is fixed on the spiral case by support, the axle head of impeller is provided with intake grill, spiral case is provided with exhaust outlet, it is characterized in that the exhaust outlet design on the spiral case has two.
Two exhaust outlets preferably are the diagonal angle and distribute, and two exhaust outlet Way outs can be parallel to each other or be vertical mutually.
The utility model double-vent centrifugal aerator, boundary dimension is little, and fabricating cost is low, and two exhaust outlets are arranged, and can realize two-way air-supply easily, and installation connects efficient and convenient.
Description of drawings
Fig. 1, the utility model one example structure schematic representation.
The left view of Fig. 2, Fig. 1.
Among the figure: 1, exhaust outlet 2, spiral case 3, support 4, intake grill 5, exhaust outlet 6, impeller 7, external rotor electric machine 8, base.
Embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, double-vent centrifugal aerator described in the utility model has spiral case 2, external rotor electric machine 7 and impeller 6, impeller 6 places in the spiral case 2 and with external rotor electric machine 7 and is connected, external rotor electric machine 7 is fixed on the spiral case 2 by support 3, and the axle head of impeller 6 is provided with intake grill 4, and spiral case 2 is provided with exhaust outlet 1, and set up second exhaust outlet 5, form two exhaust outlets, two exhaust outlets 1,5 are the diagonal angle and distribute, and the Way out of two exhaust outlets in the diagram is parallel to each other, one left, and one to the right; Also can one upwards, one is downwards; Can certainly be vertical mutually, as one left, one to inferior.
The utility model double-vent centrifugal aerator, working principle and common single vent centrifugal aerator are identical, just can realize two-way air-supply from two exhaust outlets 1,5 to different ventilation duct air-supplies, make, use all very convenient.
