Description
Technical field
This utility model relates to power plant's technical field, particularly relates to a kind of pressure fan.
Background technology
Power plant refers to the some form of original electric energy that can be converted into for fixation means or transport
The dynamics factory of electricity consumption, such as firepower, waterpower, steam, diesel oil or nuclear plant etc..Send
Blower fan (1) carries the hot-air needed for burning by air preheater to burner hearth.(2) logical
Cross primary air fan and air preheater and the heat being dried and needed for pulverized coal conveying is provided to pulverized coal preparation system
Air.(3) wind of pressure fan conveying be the hot blast of the heating exported by air preheater be two
Secondary be delivered to burner hearth so also referred to as overfire air fan.The inlet box of pressure fan is made up of steel plate,
Its effect is to make medium turn in the porch of blower fan, reduces drag losses, the one of inlet box
End is connected with the shell of blower fan by expansion joint, and the other end is connected with air channel.
Boiler is requisite equipment in power plant, existing boiler in combustion due to
Burn insufficient waste causing coal, thus need pressure fan to carry out combustion-supporting, but mesh
The driving motor of front pressure fan is arranged on inside blower housing, causes being difficult to install and maintenance.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one is sent
Blower fan.
This utility model is to be achieved through the following technical solutions:
A kind of pressure fan, including blower housing, described blower housing side is provided with fixing
Hole, opposite side is provided with air inlet protective cover, and described blower housing inner hub location is provided with solid
Determining frame, described fixed mount center is provided with rotating shaft, and described rotating shaft one end is provided with supply fan
Leaf, the other end is provided with the first belt pulley, and described first belt pulley passes through conveyer belt and second
Belt pulley is connected, described second belt pulley and the driving motor being arranged on outside blower housing
It is connected, inside described blower housing, is provided with wind scooper.
As optimal technical scheme of the present utility model, key between described rotating shaft and air inlet flabellum

Belt pulley 8 is connected, and the diameter of wherein said second belt pulley 8 is more than the first belt pulley 6
Diameter, so can improve the high speed rotating of air inlet flabellum 5.
Described second belt pulley 8 is connected with the driving motor 9 being arranged on outside blower housing 1
Connect, removably connect between wherein said driving motor 9 and blower housing 1.Described blower fan
Shell 1 is internal is provided with wind scooper 10.Motor 9 is so driven to drive the first belt pulley 8 to revolve
Turn, drive the second belt pulley 6 to rotate through transmission band 7, it is achieved the rotation of air inlet flabellum 5
Turn, be so easy to gas and enter boiler internal and carry out combustion-supporting, be the most so easy to drive motor
Installation and subsequent maintenance, easy to operate.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this
Utility model, all made within spirit of the present utility model and principle any amendment, etc.
With replacement and improvement etc., within should be included in protection domain of the present utility model.
