Abstract
A centrifugal blower designed for air delivery and forced draft is disclosed by the utility model, which comprises a housing and a frame arranged on side of the housing. A motor is fixed on the frame, and is connected with an impeller and an air inlet ring on one end, the impeller is connected to an air outlet. The impeller is on a main shaft of the motor and is directly connected with the main shaft. Profile of the impeller is a circular arc curve and bent backward with the inlet angle of 29 degrees. Shock of the blower is reduced, transmission efficiency of the motor is improved and wind power is increased as the impeller is designed to be of circular arc structure and bent backward, and is directly connected with the motor.
Description
Affiliated technical field
The utility model relates to a kind of grain machinery, particularly a kind of strength conveying, force ventilated centrifugal blower of being used for.
Background technique
The centrifugal blower of present domestic use is the blower fan of high pressure, small flow mostly, the casing side is equipped with support, fixed electrical machinery on support, connect impeller and air intake circle at motor one end, impeller is communicated with exhaust outlet, and this blower fan is because the rotation of motor and impeller brings draft power poor, the noise height, the shortcoming of galloping.
Summary of the invention
The utility model provides a kind of high pressure, big flow, the better centrifugal blower of ventilation effect for overcoming the deficiencies in the prior art.
The technical solution adopted in the utility model is: comprise casing and be installed in the support of casing side, fixed electrical machinery on support, connect impeller and air intake circle at motor one end, impeller is communicated with exhaust outlet, described impeller on electric machine main shaft and with the electric machine main shaft direct connection, the blade profile of impeller is curve of circular arc, and the back is 29 degree to bending and inlet angle.
The utility model since impeller adopt the back to the circular arc design and with the motor direct connection, reduced the vibrations of blower fan, improved the motor efficiency of transmission, increased draft power simultaneously.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail
Fig. 1 is a structural drawing of the present utility model;
Fig. 2 be among Fig. 1 A-A to view.
Embodiment
As shown in Figure 1 and Figure 2, the bottom of blower fan is a support 8, and side is that casing 1 is linked to be an integral body with support 8, fixed electrical machinery 7 on support 8, connect impeller 4 and air intake circle 3 at motor 7 one ends, impeller 4 is communicated with exhaust outlets 6, described impeller 4 on motor 7 main shafts and with motor 7 main shaft direct connections.As shown in Figure 2, the blade profile of impeller 4 is curve of circular arc, the back is 29 degree to bending and inlet angle, the impeller of this structure just makes impeller 4 form an impeller diffusion mouth 5 in exhaust outlet 6 chambeies, the exhaust outlet 6 of impeller diffusion mouth 5 also is designed to the awl mouth relatively, be the diffusion mouth of air-out, draught capacity is strengthened.Between the bottom of air intake circle 3 and casing 1 side, also be fixed with and strengthen gusset 2.
Claims (2)
1, a kind of centrifugal blower, comprise casing (1) and be installed in the support (8) of casing (1) side, go up fixed electrical machinery (7) at support (8), connect impeller (4) and air intake circle (3) at motor (7) one ends, impeller (4) is communicated with exhaust outlet (6), it is characterized in that: described impeller (4) on motor (7) main shaft and with motor (7) main shaft direct connection, the blade profile of impeller (4) is curve of circular arc, the back is 29 degree to bending and inlet angle.
2, centrifugal blower according to claim 1 is characterized in that: described impeller (4) forms an impeller diffusion mouth (5) in exhaust outlet (6) chamber.
