Abstract
A draught fan includes a motor and a drought fan main body on the rotational axis, whose inlet connected with the flue outlet of the stove, the outlet communicated with the chimney, characterized in the main body of the drought fan is provided on the shell right opposite to the inlet, a natural passage formed between the main body and the inlet and communicated with the outlet, each wind blade of the main body inclining forward to form a drought angle which is 40 degree -60 degree, bottom of the shell provided with a ash cleaning tank, the bottom of the ash cleaning tank provided with an ash cleaning outlet having a plug board switch; each wind blade of the main body of the draught fan inclines in an angle to accelerate smoke emission which improves the smoke emission efficiency, a natural passage for smoke reserved before the main body so that natural emission of smoke will not blocked when the fan stops working and is also practical.
Description
Technical field
The utility model relates to a kind of blower unit, the particularly a kind of discharging that can quicken flue gas and the unimpeded air-introduced machine in air channel when shutting down.
Background technology
In industrial or agricultural and people's life, all can use various boilers at present, these boilers all can produce the flue gas soot emissions in atmosphere, more or less the harmful substance that contains contaminated environment in the flue gas flue dust, therefore will strengthen the dedusting pollution treatment handles, for preventing the refluence of flue gas, install blower unit additional simultaneously, but existing blower unit forms closed in flue, cause flue to stop up when blower unit quits work, hindered the discharging naturally of flue gas.
In view of this, in order to overcome above-mentioned shortcoming, this creator is according to oneself practical experience and technical concept, after deliberation, exploitation, and has the utility model to produce eventually.
The utility model content
The utility model is that a kind of air-introduced machine will be provided, the unimpeded technical problem in air channel when making it accelerate fume emission speed and shutdown with solution.
It is such solving the problems of the technologies described above the technical scheme that is adopted:
A kind of air-introduced machine, include the air inducing fan in motor and the rotating shaft, its air inlet is connected in the flue outlet of body of heater, air outlet is connected with chimney, it is characterized in that: the air inducing fan of this air-introduced machine is arranged on the housing of air inlet one side, forms the natural passage that is communicated to air outlet between air inducing fan and air inlet;
Each air blade of this air inducing fan turns forward on one side and forms the inclination angle of an air inducing, and this inclination angle is 40 °～70 °;
This housing bottom is provided with the deashing bucket, and cleaning door is established in deashing bucket bottom, is equiped with the plate switch on it.
Air inducing fan of the present utility model is arranged on housing one sidewall; and the blade of air inducing fan turned forward on one side form the inclination angle of an air inducing; quicken the speed of smoke discharging; between air inducing fan and air inlet, form the natural passage of flue gas simultaneously; can prevent to hinder when air-introduced machine from stopping transport the discharging naturally of flue gas, thereby solve the unimpeded technical problem in air channel when making it accelerate fume emission speed and shutdown.
The utility model is simple in structure, and its advantage is as follows:
1, the air blade of air inducing fan of the present utility model is provided with the inclination angle of quickening fume emission, has improved fume emission efficient.
2, remain with the natural passage of flue gas before the air inducing fan of the present utility model, can not hinder the discharging naturally of flue gas during shutdown, and the tool practicality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the air blade structural representation of the utility model air inducing fan.
The specific embodiment
As shown in Figure 1, be structural representation of the present utility model, this air-introduced machine 100 includes the air inducing fan 41 in motor 40 and the rotating shaft 43, its air inlet 34 is connected in the flue outlet 10 of body of heater, air outlet 35 is connected with chimney 20, wherein, the air inducing of this air-introduced machine 100 fan 41 is arranged on the housing 30 of air inlet 34 1 sides, and air inducing fan 41 and 34 formation of air inlet are communicated to the natural passage of air outlet 35;
As shown in Figure 2, form the inclined angle alpha of an air inducing Yi Bian each air blade 42 of this air inducing fan 41 turns forward, this inclined angle alpha is 40 °～70 °;
These housing 30 bottoms are provided with deashing bucket 31, and cleaning door 32 is established in deashing bucket 31 bottoms, is equiped with plate switch 33 on it.
During work, the air blade of air inducing fan is provided with the inclination angle of quickening fume emission, has improved fume emission efficient, and remains with the natural passage of flue gas before the air inducing fan, also can not hinder the discharging naturally of flue gas when air-introduced machine is shut down, and the tool practicality.
In sum, the utility model has promoted the use effect, has practicality, meets each important document of utility model patent, so propose utility application in accordance with the law.
