Abstract
The invention relates to a dual outlet centrifugal fan, belonging to ventilation machine. The invention is provided with a spiral shell, an external rotor motor and an impeller. The impeller is arranged in the spiral shell and is connected with the external rotor motor which is fixed on the spiral shell by a bracket; the shaft end of the impeller is provided with a wind inlet; the spiral shell is provided with a wind outlet. The invention is characterized in that the spiral shell has two wind outlets. The dual outlet centrifugal fan of the invention has the advantages of small externality size, low manufacture cost, conveniently implementing bidirectional wind conveying with two wind outlets and fast and convenient installation and connection.
Description
Technical field
The present invention relates to a kind of improved centrifugal blower, belong 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.
Summary of the invention
The object of the present invention is to provide a kind of double-vent centrifugal aerator, boundary dimension is little, and fabricating cost is low, and can realize two-way air-supply easily.
Double-vent centrifugal aerator of the present invention, 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.
Double-vent centrifugal aerator of the present invention, 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, one embodiment of the invention structural 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 invention will be further described in conjunction with the foregoing description accompanying drawing.
As shown in the figure, double-vent centrifugal aerator of the present invention 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.
Double-vent centrifugal aerator of the present invention, 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.
