The centrifugal ventilating machine comprises a rear cover (1), a motor (2), a capacitor (3), a connecting piece (4), an air crust (5), an impeller (6), a filter net (7) and an air outlet (8), wherein the rear side of the motor (2) is provided with the rear cover (1); the capacitor (3) is connected with the motor (2); the motor (2) is connected with the central shaft of the air crust (5) through the connecting piece (4); the impeller (6) is arranged on the central shaft of the air crust (5); the filter net (7) is arranged on the periphery of the impeller (6); the air outlet (8) is reserved outside the air crust (5); and the motor (2) adopts a long-shaft motor. By using the centrifugal ventilating machine, an air blower can adapt high-temperature working environment, and the service life of the motor and the overall machine can be prolonged.

Description

Centrifugal blower

Technical field:

The utility model relates to a kind of ventilator, relates in particular to a kind of centrifugal blower.

Background technique:

Centrifugal blower generally is used for the room ventilation ventilation of buildings such as factory, also can be used for the high pressure forced ventilation of boiler, forge etc., and is applied to occasion such as mass transport.The kind of centrifugal blower conveying gas be air or other nonflammable explosive, to the non-corrosive gas of steel.Traditional centrifugal blower can not adapt to high-temperature work environment, and heat-resisting effect is poor, and using effect is bad, and working life is short, and noise is big.

The model utility content:

The purpose of this utility model provides a kind of centrifugal blower, and it adopts the major axis motor, can allow blower fan adapt to high-temperature work environment, and can prolong the working life of motor and complete machine.

In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises back cover, motor, electric capacity, connecting sheet, the crust of weathering, impeller, filter screen and exhaust outlet, the rear side of motor is provided with back cover, electric capacity links to each other with motor, motor links to each other with the central shaft of the crust of weathering by connecting sheet, the central shaft of the crust of weathering is provided with impeller, and the outer periphery of impeller is equipped with filter screen, and exhaust outlet is arranged on the outside of the crust of weathering.

Described motor adopts the major axis motor, can allow blower fan adapt to high-temperature work environment, and can prolong motor and complete machine working life.

Major axis motor in the utility model is the motor shaft that extends on the basis of original motor, motor separates with spiral case, and is middle with connecting sheet connection (connecting sheet length can be customized according to physical length), improves refractoriness, 90W to 7.5KW motor all can use in 90 ℃-150 ℃, and is durable for a long time.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1.

Embodiment:

With reference to Fig. 1-2, this embodiment is by the following technical solutions: it comprises back cover 1, motor 2, electric capacity 3, connecting sheet 4, the crust of weathering 5, impeller 6, filter screen 7 and exhaust outlet 8, the rear side of motor 2 is provided with back cover 1, electric capacity 3 links to each other with motor 2, motor 2 links to each other with the central shaft of the crust of weathering 5 by connecting sheet 4, the central shaft of the crust of weathering 5 is provided with impeller 6, and the outer periphery of impeller 6 is equipped with filter screen 7, and exhaust outlet 8 is arranged on the outside of the crust of weathering 5.

Described motor 2 adopts the major axis motors, can allow blower fan adapt to high-temperature work environment, and can prolong motor and complete machine working life.
