Description
Technical field
The present invention relates to a kind of optional direction compact centrifugal blowers of nuclear power station-service, belong to fan manufacturing technology field.
Background technology
Nuclear power station-service centrifugal blower is the component part of nuclear power industry ventilating system, limits, in view of the space of nuclear power plant
Nuclear power station-service centrifugal blower is asked to have sufficiently small volume to meet the requirements of installation space of nuclear power plant.Meanwhile used nuclear power
Station-service centrifugal blower angle is fixed, and to change angle need to manufacture again.
Invention content
The object of the present invention is to provide a kind of small, compact-sized, transformable optional sides of nuclear power station-service of air-out direction
To compact centrifugal blower.
In order to achieve the above objectives, the technical solution adopted in the present invention is：
A kind of optional direction compact centrifugal blower of nuclear power station-service includes current collector in casing, impeller, outer turns
Sub-motor, impeller are directly installed on external rotor electric machine, and current collector and impeller are sequentially arranged at along air inlet direction in casing, and
The air outlet of current collector enters in the air inlet of impeller（That is, the air outlet of current collector is embedded in the air inlet of impeller, but collect
The air outlet for flowing device does not contact again between each other with the air inlet of impeller）；It is opened up on casing wall body corresponding with impeller location
There are several shell air outlets, and shell air outlet is uniformly distributed along the circumferential direction of casing, while matching in each shell air outlet
Conjunction is provided with air outlet pressing plate.When the present invention needs which shell air outlet or which shell air outlet outlet air, as long as should
Air outlet pressing plate in shell air outlet is removed or is opened just.Therefore, the present invention can be by opening and closing different shell air outlets
And change wind turbine air-out direction, it can also be achieved the multiple directions outlet air simultaneously of wind turbine.
As the further setting of above-metioned scheme, the shell air outlet is provided with eight altogether.
The casing is welded by steel plate bending.
The current collector is bolted on casing.
The external rotor electric machine is bolted on casing.
It is provided with mounting blocks on the outer wall of the casing.Mounting blocks are preferably symmetrically distributed at casing both sides, it can be achieved that wind turbine
Hanging installation.
The connection between each component in the present invention is rigid connection, can avoid the rotation section because of caused by earthquake occur
Grazing between part and stationary parts.
In short, the optional direction compact centrifugal blower of nuclear power station-service of the present invention, has small, compact-sized, outlet air side
To the features such as facilitating change, be easily changed and safeguard.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the right side structural representation of Fig. 1.
Specific implementation mode
As shown in Figure 1 and Figure 2, the optional direction compact centrifugal blower of nuclear power station-service of the present invention, including be mounted in casing 1
Current collector 2, impeller 3, external rotor electric machine 4, impeller 3 is directly installed on external rotor electric machine 4, current collector 2 and impeller 3 along into
Wind direction is sequentially arranged in casing 1, and the air outlet 5 of current collector 2 enters in the air inlet 6 of impeller 3；With 3 position of impeller
Several shell air outlets 7 are offered on 1 wall body of corresponding casing, and shell air outlet 7 is uniformly divided along the circumferential of casing 1
Cloth, while air outlet pressing plate 8 is equipped in each shell air outlet 7.Impeller 3 in the present invention is preferably centrifugal leaf
Wheel.
In the present embodiment, shell air outlet 7 is provided with eight altogether.Casing 1 is welded by steel plate bending.Outside casing 1
Mounting blocks 9 are provided on wall.
Current collector 2 is bolted on casing 1.Current collector 2 uses precision between streamline curve, with impeller 3 to match
It closes, so that wind turbine air inlet loss is reached minimum, improve fan efficiency.Impeller 3 uses high efficiency, low noise biobjective scheduling is set
Meter, characteristic curve of fan is flat, and high efficient district range is big.
External rotor electric machine 4 is bolted on casing 1.
Air outlet pressing plate 8 is mounted on by bolt in shell air outlet 7.
In use, the requirement according to user to air outlet angle, opens the air outlet pressing plate 8 in corresponding shell air outlet 7,
Shell air outlet 7 and current collector 2 are attached with pipeline as required.Power on, external rotor electric machine 4 operates, by turning outside
4 impeller 3 of sub-motor operates, and air is made to enter current collector 2, then the air outlet by current collector 2 from the air inlet of current collector 2
5 enter impeller 3, finally carry out air-supply or air draft from the shell air outlet 7 of casing 1.
Above-described embodiment is only used for illustrating the inventive concept of the present invention, rather than the restriction to rights protection of the present invention,
All changes for carrying out unsubstantiality to the present invention using this design, should all fall into protection scope of the present invention.
