Description
Technical field
The invention belongs to ventilation blower technical field, and in particular to a kind of boiler centrifugal fan constructional device.
Background technology
At present, existing mesolow centrifugal fan includes motor, and the rotating shaft of the motor is cased with impeller, the impeller it is outer
Portion is provided with shell, and the shell is provided with air inlet and air outlet, and the impeller includes hub disk, shroud, the hub disk, shroud
Between be connected with blade.The shortcomings that this centrifugal fan is exactly that hub disk is flat disk, the space length between hub disk and shroud compared with
Greatly, the blade connected between this is required is larger, and blade is big, and the frictional ratio of gas and blade is big during wheel rotation, energy damage
Consumption is big, and for the small motor of parameter surplus, its service life is shorter, and the motor that selection parameter surplus is larger, so not
Electric energy is only wasted, and increases noise pollution.
The content of the invention
It is an object of the invention to provide a kind of boiler centrifugal fan constructional device, solve present in such scheme not
Foot.
In order to achieve the above object, the technical solution used in the present invention is：
A kind of boiler centrifugal fan constructional device, mainly by V band belt wheel, bearing block, main shaft, reel, hub disk, spiral case, shroud,
Air inlet, air outlet and base composition, described base top are provided with bearing block, passed through in bearing block provided with main shaft, and main shaft is right
End is provided with V band belt wheels, and main shaft left end is extend into reel, and reel is arranged in spiral case, and air outlet is provided with below spiral case, and spiral case is left
Side is provided with air inlet, and connection air inlet side is provided with shroud in spiral case, and shroud the right is provided with hub disk in spiral case.
Described bearing block is provided with two side by side.
Blade is provided between described shroud and hub disk.
The present invention is simple in construction, and impeller is easy for installation, and noise pollution is small, relative energy-saving and service life length.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
1-V band belt wheels；2- bearing blocks；3- main shafts；4- reels；5- hub disks；6- spiral cases；7- shrouds；8- air inlets；9- air outlets；
