Description
Technical field
This utility model relates to power plant's technical field, particularly relates to a kind of injecting type pressure fan.
Background technology
Power plant refers to for fixation means or the some form of original electric energy that can be converted into is transported electricity consumption
Dynamics factory, such as firepower, waterpower, steam, diesel oil or nuclear plant etc..Pressure fan (1) is passed through
Air preheater hot-air needed for burner hearth conveying burning.(2) by primary air fan and air preheat
Device provides the hot-air being dried and needed for pulverized coal conveying to pulverized coal preparation system.(3) wind of pressure fan conveying is
The hot blast of the heating exported by air preheater is that second-pumping is to burner hearth so also referred to as overfire air fan.
The inlet box of pressure fan is made up of steel plate, and its effect is to make medium turn in the porch of blower fan, reduces
Drag losses, one end of inlet box is connected with the shell of blower fan by expansion joint, the other end and air channel phase
Even.
Boiler is requisite equipment in power plant, and existing boiler is in combustion due to burning not
Fully causing the waste of coal, thus need pressure fan to carry out combustion-supporting, general ventilating blower structure is multiple
Miscellaneous, the most defeated wind velocity is slow, affects combustion-supporting effect.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of injecting type send
Blower fan.
This utility model is to be achieved through the following technical solutions:
A kind of injecting type pressure fan, including support, described pedestal upper end is provided with blower housing, described wind
Machine shell side is round table-like structure, and described blower housing side is provided with exhaust vent, outside described blower fan
Shell opposite side is provided with air intake containment vessel, and described air intake containment vessel is provided with several louvres, described
Blower housing center is provided with driving motor, and described driving motor output end is connected with air intake flabellum,
Described blower housing sidewall is provided with several fresh air inlets.
As optimal technical scheme of the present utility model, between described air intake containment vessel and blower housing it is
Removably connect.
As optimal technical scheme of the present utility model, it is key between described driving motor and air intake flabellum
Connect.
As optimal technical scheme of the present utility model, the planform of described fresh air inlet be oval or
Strip.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction,
Reasonable in design, this utility model, by setting centrally-mounted driving, air intake flabellum, so drives driven by motor
The rotation of air inlet flabellum, so makes outside air enter inside blower housing from fresh air inlet, through going out
Air holes is discharged, and so can improve the speed that air is discharged, and improves the effect of boiler combustion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. support；2. blower housing；3. air intake containment vessel；301. louvre；4. drive electricity

Connect, so drive motor 4 can drive the high speed rotating of air intake flabellum 5, it is simple to the conveying of cold wind.
Described driving motor 4 outfan is connected with air intake flabellum 5, on described blower housing 2 sidewall
Being provided with several fresh air inlets 6, the planform of wherein said fresh air inlet 6 is oval or strip, so
The air being easy to the external world enters blower housing 2 inside through fresh air inlet 6.
During use, so drive motor 4 to drive the rotation of air inlet flabellum 5, so make outside air
Enter blower housing 2 from fresh air inlet 6 internal, discharge through exhaust vent 7, so can improve air
The speed discharged, improves the effect of boiler combustion.
In description of the present utility model, unless otherwise clearly defined and limited, term " install ",
" be connected ", " connection ", " fixing " should be interpreted broadly, and connect for example, it may be fixing,
Can also be to removably connect, or integral；Can be to be mechanically connected, it is also possible to be electrical connection；Can
Being to be joined directly together, it is also possible to be indirectly connected to by intermediary, can be the company of two element internals
Lead to or the interaction relationship of two elements.For the ordinary skill in the art, can have
Body situation understands above-mentioned term concrete meaning in this utility model.
The foregoing is only preferred embodiment of the present utility model, not new in order to limit this practicality
Type, all any amendment, equivalent and improvement made within spirit of the present utility model and principle
Deng, within should be included in protection domain of the present utility model.
