Description
Technical field
This utility model relates to a kind of boiler induced-draft fan, belongs to blower fan technical field.
Background technology
In the installation and use of boiler induced-draft fan, the air outlet of air-introduced machine can be linked together by the ventilation shaft of outlet air flange Yu boiler.But there are some problems in actual use: 1, sometimes the installation direction of air-introduced machine is limited by place, the position of air outlet is not corresponding with the position of ventilation shaft interface, connects to pipeline and make troubles；2, air-introduced machine install rear air outlet towards just immobilizing, when needs change ventilation shaft connect time, bother very much.
Utility model content
Technical problem to be solved in the utility model is in that to overcome the problems referred to above, and provides the boiler induced-draft fan that a kind of closure is flexible, the suitability is strong.
The technical solution of the utility model is:
A kind of boiler induced-draft fan, including casing, impeller, rotating shaft and dynamical system, described impeller is arranged in casing, one end of described rotating shaft is fixing connects dynamical system, the other end stretches into that casing and impeller are fixing to be connected, described casing has air inlet and air outlet, it is characterized in that: described air outlet is provided with the hose adapter device of Bendable telescopic for connecting ventilation shaft, described hose adapter device includes bellows and is connected to the first connection dish at bellows two ends, second connection dish, one end of hose adapter device is connected to the air outlet of casing by the first connection dish, the other end is connected with ventilation shaft by the second connection dish；Having the cannelure holding bellows on described first connection dish, described second connection dish has the ring plug matched with described cannelure, one end of bellows is fixedly connected on the bottom land of cannelure, and the other end is fixedly connected on ring plug.Can stretching according to the position of ventilation shaft interface and bending bellows during installation, use flexibly, the suitability is strong, it is not necessary to during use, it is also possible to bellows compression be received in cannelure.
Further, the inner headed face of the ring plug of the second connection dish described in the utility model has annular protrusion, the inner side cell wall of the cannelure of the first connection dish offers the annular slot matched with described annular protrusion.Annular protrusion and annular slot be arranged to fixing in cannelure of ring plug after storage bellows.
Further, bellows described in the utility model is plastic film capicitor.
The beneficial effects of the utility model are: arrange the hose adapter device of Bendable telescopic at fan out draft place, when installing and using, can stretch according to the position of ventilation shaft interface and bending bellows, closure is flexible, easy for installation, the suitability is strong, it is not necessary to during use, can also bellows compression be received in cannelure, save space.

Fig. 2 be hose adapter device compression time structural representation.
Fig. 3 be hose adapter device launch time structural representation.
Fig. 4 is P place enlarged drawing in Fig. 2.
Detailed description of the invention
In conjunction with drawings and Examples, this utility model is further described:
As shown in Figure 1, the boiler induced-draft fan of the present embodiment, including casing 10, impeller 20, rotating shaft 30 and dynamical system 40, impeller 20 is arranged in casing 10, one end of rotating shaft 30 is fixing connects dynamical system 40, the other end stretches into that casing 10 and impeller 20 is fixing to be connected, thus dynamical system 40 impeller 20 rotates.Casing 10 has air inlet 11 and air outlet 12, and in order to the installation closure making boiler induced-draft fan is more flexible, the suitability is higher, is provided with the hose adapter device of Bendable telescopic for connecting ventilation shaft on air outlet 12.
As shown in Figures 2 and 3, hose adapter device includes bellows 50 and is connected to first connection dish 60, the second connection dish 70 at bellows 50 two ends, bellows 50 is plastic film capicitor, one end of hose adapter device is connected to air outlet 12 place of casing 10 by the first connection dish 60, and the other end is connected with ventilation shaft by the second connection dish 70.Having the cannelure 61 holding bellows 50 on first connection dish 60, the second connection dish 70 has the ring plug 71 matched with described cannelure 61, one end of bellows 50 is fixedly connected on the bottom land of cannelure 61, and the other end is fixedly connected on ring plug 71.Wherein, as shown in Figure 4, the inner headed face of ring plug 71 has annular protrusion 72, the inner side cell wall of cannelure 61 offers the annular slot 62 matched with this annular protrusion 72.
During use, being pulled out by ring plug 71 from cannelure 61, bellows 50 launches, and then stretches according to the position of ventilation shaft interface and bending bellows 50, and is connected with ventilation shaft by the second connection dish 70.When need not use, promote ring plug 71, bellows 50 compression is received in cannelure 61, continues to push away, ring plug 71 is pushed cannelure 61, make annular protrusion 72 snap in annular slot 62.
It is understood that for the person of ordinary skill of the art, it is possible to make other various corresponding changes and deformation according to technology of the present utility model design, and all these change and deformation all should belong to this utility model scope of the claims.
