Abstract
The utility model discloses a novel centrifugal fan comprising a base, a support, an impeller, a volute, a belt and a motor, wherein the motor is fixed on the base and connected with the impeller through the belt; the volute is provided with an air inlet and an air outlet and fixed on the base; one side of the volute is strengthened and fixed on the base by the support; the impeller is provided with multiple wings and arranged between the air inlet and the air outlet; and a current collector is arranged in the volute and between the impeller and the air outlet and has the functions of rectification and noise reduction. The novel centrifugal fan has strong applicability, high efficiency, large flow, small noise, compact structure and light weight, and occupies small areas, thus being widely applicable to the manufacturing of centrifugal fans.
Description
Technical field
The utility model relates to a kind of Fan Equipment, relates in particular to a kind of novel centrifugal blower fan.
Background technique
Existing centrifugal blower is in order to pursue the efficient height, and exhausting is effective, generally all is designed to the centrifugal blower of box-type, and the centrifugal blower structure of this box-type is compact inadequately, and volume is big, and noise is big, and floor space is big, is unfavorable for installing.In addition, when existing centrifugal blower wants the big and efficient of dependable flow high, just need bigger power, energy consumption is also just high relatively, thereby financial cost is also with regard to increase.
Summary of the invention
The utility model is at the deficiencies in the prior art, and purpose is to provide a kind of novel centrifugal blower fan, has compact structure, floor space is little, and noise is low, characteristics such as efficient height.
In order to achieve the above object, the utility model adopts following technological scheme: a kind of novel centrifugal blower fan, comprise base, support, impeller, spiral case, belt and motor, and motor is fixed on the base, connects impeller by belt.Described spiral case is provided with intake grill and exhaust outlet, and spiral case is fixed on the base, and a side of spiral case is strengthened being fixed on the base by support; Described impeller is the multiple-airfoil type impeller, between the intake grill and exhaust outlet in spiral case; Slip ring is installed in the spiral case, between impeller and exhaust outlet, plays rectification, noise reduction effect.
Working principle: during work, motor rotates by the belt impeller, produces negative-pressure sucking, and air is sucked in the spiral case from intake grill, after the supercharging of multiple-airfoil type impeller, by the rectified action of slip ring, blows from exhaust outlet.The utility model product applicability is strong, the efficient height, flow is big, noise is little, compact structure, in light weight, floor space is little, thereby can be widely used in the making of centrifugal blower.
Description of drawings
Fig. 1 is the plan view of the utility model structural representation; Fig. 2 is the left view of the utility model structural representation.
Among the figure: 1, base, 2, support, 3, intake grill, 4, impeller, 5, exhaust outlet, 6, spiral case, 7, belt, 8, motor, 9, slip ring.
Embodiment
Embodiment: as depicted in figs. 1 and 2, a kind of novel centrifugal blower fan comprises base 1, support 2, impeller 4, spiral case 6, belt 7 and motor 8, and motor 8 is fixed on the base 1, connects impeller 4 by belt 7.Described spiral case 6 is provided with intake grill 3 and exhaust outlet 5, and spiral case 6 is fixed on the base 1, and a side of spiral case 6 is strengthened being fixed on the base 1 by support 2; Described impeller 4 is the multiple-airfoil type impeller, between the intake grill 3 and exhaust outlet 5 in spiral case 6; Slip ring 9 is installed in the spiral case 6, between impeller 4 and exhaust outlet 5, plays rectification, noise reduction effect.
Working principle: during work, motor 8 rotates by belt 7 impeller 4, produces negative-pressure sucking, and air is sucked in the spiral case 6 from intake grill 3, after 4 superchargings of multiple-airfoil type impeller, by the rectified action of slip ring 9, blows from exhaust outlet 5.The utility model product applicability is strong, the efficient height, flow is big, noise is little, compact structure, in light weight, floor space is little, thereby can be widely used in the making of centrifugal blower.
