Abstract
The utility model discloses a low-noise cabinet type centrifugal fan. The low-noise cabinet type centrifugal fan comprises a chassis, a fan and a motor, wherein the fan is arranged inside the chassis; and the motor is arranged outside the chassis. The low-noise cabinet type centrifugal fan is characterized in that a silencing panel is arranged in the chassis; current collectors are arranged at the two ends of a fan impeller; the chassis is provided with an air inlet and an air outlet; the chassis and the motor are fixed on a base; and the motor is connected with the fan through a belt; and a belt cover is arranged outside the belt. The low-noise cabinet type centrifugal fan has the advantages that design is unique, structure is simple and appearance is attractive and elegant; on one hand, vibration noise produced during work of the fan and the motor is reduced, and on the other hand, noise produced by air flow during work of the fan is reduced; and the low-noise cabinet type centrifugal fan is convenient and practical.
Description
Technical field:
The utility model relates to the cabinet type centrifugal blower of a kind of low noise, belongs to the technological improvement of blower fan.
Background technique:
Advantage such as cabinet type centrifugal blower has that resistance to high temperature is good, compact structure, outward appearance are clean and tidy, easy to install, so be widely used in places such as industry, civil building and basement, its structure generally includes housing, blower fan, motor, chassis lamp part.The cabinet type centrifugal blower of traditional low noise generally is equipped with vibration damper, but vibration damper is installed in the outside, and a base also will be installed simultaneously, has increased cost on the one hand, influences the attractive in appearance of blower fan; On the other hand, simple reduce the noise of blower fan by vibration damping, DeGrain, and can be affected the working life of the component of whole typhoon machine.
The model utility content:
The purpose of this utility model is exactly the deficiency at prior art, and provides a kind of low noise cabinet type centrifugal blower, and design is unique, and is simple in structure, elegant in appearance, the noise that produces in the time of effectively reducing blower fan work.
In order to achieve the above object, the technical solution of the utility model is as follows: the cabinet type centrifugal blower of a kind of low noise, comprise casing, be installed in the blower fan in the casing and be installed in the outer motor of casing, it is characterized in that: the noise elimination panel is housed in the casing, the draught fan impeller two ends are equipped with slip ring, and described casing is provided with intake grill and exhaust outlet, and casing and motor are fixed on the base, motor connects blower fan by belt, and belt has belt housing outward.
Beneficial effect: the utility model design is unique, simple in structure, elegant in appearance, the vibrating noise that has produced when having reduced blower fan and machine operation on the one hand, and the noise that has flowed and produced owing to air when having reduced blower fan work on the other hand, convenient and practical.
Description of drawings:
Fig. 1 is plan view of the present utility model;
Fig. 2 is left view of the present utility model.
Among the figure: 1, exhaust outlet, 2, the noise elimination panel, 3, casing, 4, intake grill, 5, motor, 6, belt, 7, blower fan, 8, base, 9, slip ring, 10, belt housing, 11, draught fan impeller.
Embodiment:
Embodiment: see illustrated in figures 1 and 2, the cabinet type centrifugal blower of a kind of low noise, comprise casing 3, be installed in the blower fan 7 in the casing 3 and be installed in casing 3 motor 5 outward, described casing 3 comprises exhaust outlet 1, intake grill 4 and noise elimination panel 2, slip ring 9 is equipped with at draught fan impeller 11 two ends of described blower fan 7 the insides, casing 3 and motor 5 are fixed on the base 8, and described motor 5 connects blower fan 7 by belt 6, and belt housing 10 is housed on the belt 6.
The utility model is installed in blower fan 7 in the cabinet type casing 3, and noise elimination panel 2 is installed in the housing of casing 3, and slip ring 9 is installed at draught fan impeller 11 two ends, and the noise that has produced when greatly having reduced blower fan work is simple in structure, elegant in appearance.Motor 5 and casing 3 are fixed on the base 8, and described base 8 has certain effectiveness in vibration suppression, the vibrating noise that has produced when so just having solved blower fan and machine operation.In addition, pulley cover 10 protection belts are not polluted by extraneous dust and other impurities, have increased Security again.
