Abstract
This utility model one centrifugal exhaust fan, form including motor, air outlet, air inlet, Blower Housing, power transmission shaft, wind wheel blade and electric machine support, the side of air exhauster housing is provided with air outlet, air exhauster housing includes that protecgulum and bonnet form air channel, motor be connected with wind wheel and together be fixed on bonnet, protecgulum is provided with air inlet, and wind wheel body is provided with the electric machine support of fixing motor, and electric machine main shaft overlaps with the rotational axis line of wind wheel body.This utility model simple in construction, is effectively improved air exhauster wind-force, and wind wheel blade top layer is provided with ceramic layer, overcomes the deficiency of existing air exhauster, the most energy-conservation, safety completely, and service life is the longest.
Description
Technical field
This utility model relates to the technical field of air exhauster, is specifically related to a kind of centrifugal exhaust fan.
Background technology
Air exhauster is again effluent aerator, centrifugal blower, small blast fan, is a kind of air blowing or the dual-purpose general source of the gas of air-breathing, it is common that for the air-breathing of plant equipment, as the term suggests being also air exhauster.Existing blower fan structure is complicated, there is the problems such as efficiency is low, the life-span is short.
Utility model content
The purpose of this utility model is to provide a kind of centrifugal exhaust fan, to solve the existing problem that air exhauster strength is little, the life-span is short.
The technical solution of the utility model is: a kind of centrifugal exhaust fan, the side of described air exhauster housing is provided with air outlet, Blower Housing includes that protecgulum and bonnet form air channel, motor is connected by power transmission shaft solidity with wind wheel blade, protecgulum is provided with air inlet, described wind wheel body is provided with the receiving cavity of fixing motor, and electric machine main shaft overlaps with the rotational axis line of Blower Housing.
Described wind wheel blade outer surface is provided with one layer of ceramic protection cover.
Described wind wheel blade uses metal material to make.
The beneficial effects of the utility model are: a kind of centrifugal exhaust fan, and this scenario-frame is simple, is effectively improved air exhauster wind-force, and wind wheel blade top layer is provided with ceramic layer, overcome the deficiency of existing air exhauster completely, and energy-conservation, safety, efficiency height, service life is the longest.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model；
1-motor；2-air outlet；3-air inlet；4-Blower Housing；5-power transmission shaft；6-wind wheel blade；7-electric machine support.
Detailed description of the invention
As shown in Figure 1, this utility model centrifugal exhaust fan is mainly by motor 1, air outlet 2, air inlet 3, Blower Housing 4, power transmission shaft 5, wind wheel blade 6 and electric machine support 7 form, the side of air exhauster housing 4 is provided with air outlet 2, Blower Housing 4 wind wheel blade 6 uses metal material to make, wind wheel blade 6 outer surface is provided with one layer of ceramic protection cover, inside becomes air channel by 6 rotaries of wind wheel leaf, motor 1 is connected by power transmission shaft 5 solidity with wind wheel blade 6, cavity is provided with air inlet 3, described wind wheel body is provided with the electric machine support 7 of fixing motor, electric machine main shaft 5 overlaps with the rotational axis line of wind wheel blade 6.
After switching on power, motor 1 drives wind wheel blade 6 to rotate by power transmission shaft 5, and Blower Housing 4 is internal by producing negative pressure at air inlet 3, utilizes the wind wheel blade 6 of high speed rotating to be accelerated by gas, then slows down, changes the flow direction, make kinetic energy be converted into potential energy (pressure).In blower fan, gas is from axially into wind wheel blade 6, and gas is radially redirected when flowing through wind wheel blade, subsequently into diffuser.In diffuser, gas and changing flow direction and conduit section area increase makes the flow slowing down, this decelerating effect convert kinetic energy into pressure energy, thus reaches the effect of convulsion.
Certainly, technique scheme is preferred forms of the present utility model, and any improvement made under without departing from spirit background of the present utility model, within all falling within protection domain of the present utility model.
Claims (2)
1. a centrifugal exhaust fan, it is made up of motor, air outlet, air inlet, Blower Housing, power transmission shaft, wind wheel blade and electric machine support, it is characterized in that: the side of described Blower Housing is provided with air outlet, air exhauster housing includes that protecgulum and bonnet form air channel, motor is connected by power transmission shaft solidity with wind wheel blade, protecgulum is provided with air inlet, described wind wheel body is provided with the electric machine support of fixing motor, wind wheel blade outer surface is provided with one layer of ceramic protection cover, and electric machine main shaft overlaps with the rotational axis line of Blower Housing.
