Abstract
The utility model relates to a nuclear power plant is with optional direction compact centrifugal fan belongs to fan manufacturing technical field, including installing collector, impeller, the external rotor electric machine in the casing, the impeller direct mount is on the external rotor electric machine, and collector and impeller are installed in the casing along the air inlet direction in proper order, and the air outlet of collector gets into to the air intake of impeller in, with seted up a plurality of casing air outlet on the corresponding casing wall body in impeller position, and casing air outlet along the circumference evenly distributed of casing, simultaneously on each casing air outlet all the cooperation be provided with the air outlet clamp plate. The utility model discloses nuclear power plant is with optional direction compact centrifugal fan has small, compact structure, the air -out direction makes things convenient for characteristics such as change, be liable to change and maintenance.
Description
Technical field
The utility model relates to a kind of nuclear power plant optional direction compact type centrifugal blower, belongs to fan manufacturing technology field.
Background technique
Nuclear power plant is the constituent element of nuclear power industry ventilation system with centrifugal blower, in view of the spatial constraints of nuclear power plant, requires that nuclear power plant's centrifugal blower has enough little volume to meet the requirements of installation space of nuclear power plant.Meanwhile, used nuclear power plant is all fixing by centrifugal blower angle, and change angle need manufacture again.
Model utility content
The purpose of this utility model is to provide that a kind of volume is little, the transformable nuclear power plant of compact structure, air-out direction optional direction compact type centrifugal blower.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of nuclear power plant optional direction compact type centrifugal blower, comprise the slip ring be arranged in casing, impeller, external rotor electric machine, impeller is directly installed on external rotor electric machine, slip ring and impeller are arranged in casing successively along air intake direction, and the intake grill that the exhaust outlet of slip ring enters to impeller is interior (namely, the exhaust outlet of slip ring is embedded in the intake grill of impeller, but the exhaust outlet of slip ring does not contact again each other with the intake grill of impeller); The casing wall body corresponding with impeller location offers several shell air outlet, and shell air outlet is uniformly distributed along the circumference of casing, each shell air outlet is all equipped with exhaust outlet pressing plate simultaneously.When the utility model needs which shell air outlet or which shell air outlet air-out, as long as the exhaust outlet pressing plate in this shell air outlet is taken off or opens.Therefore, the utility model changes blower fan air-out direction by opening and closing different shell air outlet, also can realize the multiple directions air-out simultaneously of blower fan.
As the further setting of such scheme, described shell air outlet is provided with eight altogether.
Described casing is welded by steel plate bending.
Described slip ring is bolted on casing.
Described external rotor electric machine is bolted on casing.
The outer wall of described casing is provided with mounting blocks.Mounting blocks is preferably symmetrically distributed in casing both sides, and the hanging that can realize blower fan is installed.
Connection between each parts in the utility model is and is rigidly connected, the grazing between the rotatable parts that appearance can be avoided to cause because of earthquake and static part.
In a word, the utility model nuclear power plant optional direction compact type centrifugal blower, has that volume is little, compact structure, air-out direction are conveniently changed, is easy to change and the feature such as maintenance.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right TV structure schematic diagram of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the utility model nuclear power plant optional direction compact type centrifugal blower, comprise the slip ring 2 be arranged in casing 1, impeller 3, external rotor electric machine 4, impeller 3 is directly installed on external rotor electric machine 4, slip ring 2 and impeller 3 are arranged in casing 1 successively along air intake direction, and the exhaust outlet 5 of slip ring 2 enters in the intake grill 6 of impeller 3; Casing 1 wall body corresponding with impeller 3 position offers several shell air outlet 7, and shell air outlet 7 is uniformly distributed along the circumference of casing 1, each shell air outlet 7 is all equipped with exhaust outlet pressing plate 8 simultaneously.Impeller 3 in the utility model is preferably receded disk impeller.
In the present embodiment, shell air outlet 7 is provided with eight altogether.Casing 1 is welded by steel plate bending.The outer wall of casing 1 is provided with mounting blocks 9.
Slip ring 2 is bolted on casing 1.Slip ring 2 adopts streamline curve, and precision-fit between impeller 3, makes the loss of blower fan air intake reach minimum, improves fan efficiency.Impeller 3 have employed high efficiency, the design of low noise biobjective scheduling, and characteristic curve of fan is smooth, and efficient district scope is large.
External rotor electric machine 4 is bolted on casing 1.
Exhaust outlet pressing plate 8 is arranged in shell air outlet 7 by bolt.
During use, according to the requirement of user to exhaust outlet angle, open the exhaust outlet pressing plate 8 in corresponding shell air outlet 7, shell air outlet 7 is connected with pipeline on request with slip ring 2.Switch on power, external rotor electric machine 4 operates, and is operated by external rotor electric machine 4 impeller 3, makes air enter slip ring 2 from the intake grill of slip ring 2, enter impeller 3 by the exhaust outlet 5 of slip ring 2 again, finally carry out blowing or air draft from the shell air outlet 7 of casing 1.
Above-described embodiment only illustrates inventive concept of the present utility model for explaining, but not the restriction to the utility model rights protection, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should fall into protection domain of the present utility model.
