Abstract
The utility model discloses an efficient blower fan. The efficient blower fan comprises a casing, wherein an air inlet is formed in the left wall of the casing, an air outlet is formed in the right wall of the casing, and an air collection hood is arranged at the air inlet; a motor and a wind wheel are arranged in the casing, the motor comprises a rotating shaft connected with the wind wheel, the wind wheel right faces the air collection hood, the wind wheel comprises rotating blades, a detachable installation plate is arranged on the left wall of the casing, the air inlet is formed in the installation plate, and the position, corresponding to the motor, of the rear end of the wind wheel is provided with a detachable dustproof piece; the left side edge of each rotating blade is arc, the right side edge of each rotating blade is in a fold line shape, and an arc protruding edge is arranged at one end of each rotating blade. In this way, dust and other impurities can be prevented from entering the motor from fin gaps of the rotating shaft along with air currents, and normal operation of the motor is guaranteed; noise produced by friction between the rotating blades and wind when the rotating blades rotate is avoided, and the protruding edges can change the directions of the wind blowing towards two sides, so that the wind blows in the horizontal direction and it is avoided that the wind impacts the casing to produce noise; meanwhile, working efficiency of the blower fan is improved.
Description
Technical field
The utility model relates to mechanical engineering field, especially relates to a kind of air-foil fan.
Background technique
Existing blower fan comprises upper casing and lower housing, need dismantle casing and keep in repair, but casing is very heavy when maintenance, dismounting difficulty, maintenance is inconvenient, and in the middle of two-part casing, finedraw is large, when blower fan is used for transport gas, Leakage Gas is many, easily befouling environment, and dust and other impurities can enter in motor from the finedraw of rotating shaft with air-flow, is stuck between motor internal part, affect the rotation of motor, and then reduced the working efficiency of blower fan; When simultaneously the rotor of wind wheel rotates, produce noise with wind friction, wind can blow to the both sides of wind wheel, and wind-force impacts casing generation noise, has reduced the working efficiency of blower fan.
Model utility content
The utility model, in order to overcome the deficiencies in the prior art, provides one to prevent that dust and other impurities from entering motor, the air-foil fan of protection of the environment.
To achieve these goals, the utility model by the following technical solutions: a kind of air-foil fan, comprise casing, the left wall of described casing is provided with intake grill, right wall is provided with exhaust outlet, intake grill place is provided with wind-collection cover; In described casing, be provided with motor and wind wheel, described motor comprises the rotating shaft that connects wind wheel, wind wheel is just to wind-collection cover setting, wind wheel comprises rotor, the left wall of described casing is provided with dismountable mounting plate, intake grill is located on mounting plate, and the rear end of described wind wheel and motor corresponding part are provided with dismountable dustproof sheet; The limit, left side of described rotor is curved, and the right edge of rotor is fold-line-shaped, and the end of rotor is provided with the chimb of arc.
As preferably, described chimb is welded on rotor, and described dustproof sheet is screwed the rear end in wind wheel.
As preferably, described rotor is 7.
In sum, the utlity model has following advantage: mounting plate is set, and dismounting and installation are easily, easy to maintenance, and finedraw is little simultaneously, avoids for transport gas process befouling environment; This dustproof sheet is set and can prevents that dust and other impurities from entering in motor from the finedraw of rotating shaft with air-flow, avoid dust and other impurities to exert an influence to the running of motor, guaranteed the normal operation of motor; When this setting avoids rotor to rotate, produce noise with wind friction, and chimb can change the wind direction that blows to two crosswind, its wind direction is directed to substantially horizontal, avoid wind to impact casing generation noise, improve the working efficiency of blower fan simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is carried out to clear, complete description.
As shown in Figure 1, a kind of air-foil fan, comprises casing 1, and the left wall of described casing 1 is provided with intake grill, and right wall is provided with exhaust outlet 12, and intake grill place is provided with wind-collection cover 13; In described casing 1, be provided with motor 2 and wind wheel 3, this motor 2 is fixed on the roof in casing 1, described motor 2 comprises the rotating shaft and the motor body that connect wind wheel 3, wind wheel 3 just arranges wind-collection cover 13, wind wheel 3 comprises rotor 31, the left wall of described casing 1 is provided with dismountable mounting plate 14, and intake grill is located on mounting plate 14; This mounting plate is set, and dismounting and installation are easily, easy to maintenance, and finedraw is little simultaneously, avoids for transport gas process befouling environment.
The rear end of described wind wheel 3 and motor 2 corresponding parts are provided with dismountable dustproof sheet 32, described dustproof sheet is circular, in the middle of it, be provided with the perforation through motor 2 rotating shafts, and the outward edge of dustproof sheet 32 exceeds rotating shaft and forms certain distance, the distance that this distance can be separated by according to wind wheel 3 and motor 2 bodies is adjusted; This dustproof sheet is set and can prevents that dust and other impurities from entering in motor from the finedraw of rotating shaft with air-flow, avoid dust and other impurities to exert an influence to the running of motor, guaranteed the normal operation of motor.
Concrete, the limit, left side of described rotor 31 is curved, the right edge of rotor 31 is fold-line-shaped, the end of rotor 31 is provided with the chimb 311 of arc, when this setting avoids rotor to rotate, with wind friction generation noise, and chimb can change the wind direction that blows to two crosswind, and its wind direction is directed to substantially horizontal, avoid wind to impact casing and produce noise, improved the working efficiency of blower fan simultaneously.
For fear of wind wheel, the high speed rotating in the situation that, chimb departs from rotor, and described chimb 311 is welded on the end of rotor 31; For the ease of dustproof sheet is cleared up, improve using effect, described dustproof sheet 32 is screwed in the rear end of wind wheel 3.
How many meetings of the quantity of described rotor exert an influence to the working efficiency of wind wheel, through overtesting, confirm, and when rotor quantity is 7, wind wheel working efficiency the best of this setting.
Obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all should belong to the scope of the utility model protection.
