Abstract
The utility model discloses a low-noise cabinet type centrifugal fan, which comprises a housing, a fan and a motor, wherein the fan is arranged in the housing; the motor is arranged outside the housing; the centrifugal fan is characterized in that: noise produced during work of the fan can be effectively reduced by a silencing panel in a housing body of the housing and current collectors at the two ends of a fan impeller; the housing is provided with an air inlet and an air outlet; the housing and the motor are fixed on a pedestal; and the pedestal has a certain vibration reduction function, so that vibration noise produced during work of the fan and the motor can be effectively reduced. The low-noise cabinet type centrifugal fan has a unique design, a simple structure and attractive and elegant appearance; 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 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 is produced 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 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 that noise elimination panel that is equipped with in the housing of casing and the slip ring that is installed in the draught fan impeller two ends are produced in the time of effectively reducing blower fan work.
Described casing is provided with intake grill and exhaust outlet, and casing and motor are fixed on the base.
Described base has certain vibration-damping function, the vibrating noise that is produced in the time of effectively reducing blower fan and machine operation.
Described motor connects blower fan by belt, and belt has belt housing outward, can protect belt not by pollutions such as dusts, has also played the safety protection effect.
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 produced owing to air flows when having reduced blower fan work on the other hand, convenient and practical.
Description of drawings:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a 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 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 existing existing effectiveness in vibration suppression of ventilator is poor, noise big in order to solve, the problem of unreasonable structure, the utility model is installed in blower fan 7 in the cabinet type casing 3, noise elimination panel 3 is installed in the housing of casing 3, slip ring 9 is installed at draught fan impeller 11 two ends, the noise that has been produced when greatly having reduced blower fan work, 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 been 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.
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 produced owing to Air Flow when having reduced on the other hand blower fan work, convenient and practical.
