General blower fan comprises shell, is located at wind wheel and motor in shell, and the rotating shaft of described motor connects described wind wheel, and wind wheel generally includes the steel disc of even thickness; The centrifugal centrifugal force of even thickness of steel disc is little, and rotational speed is slow, the inefficiency of blower fan; Blower fan uses for a long time, a lot of dust and other impurities on wind wheel, have easily been amassed, and wind wheel is generally non-dismountable structure, the foreign material on wind wheel and dust cannot be removed totally, use for a long time, the wind wheel corrosion that gets rusty easily, and then cause blower fan to break down, and shorten the working life of blower fan, need to change whole wind wheel, waste resource has improved maintenance cost simultaneously.
Model utility content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of working efficiency high, the box-type centrifugal fan that maintenance cost is low.
To achieve these goals, the utility model by the following technical solutions: a kind of box-type centrifugal fan, comprises motor cabinet, is located at the motor at motor cabinet top and is located at the shell of motor left end; The left wall of described shell has wind inlet, and shell roof has exhaust outlet, and the rotating shaft of described motor is connected with the wind wheel in shell through the right wall of shell; Described wind wheel comprise fixed cover, mounting cover and be located at fixed cover and mounting cover between limb, described limb both sides are plugged in respectively on fixed cover and mounting cover, described fixed cover and mounting cover approach outer edge and are equipped with at least 3 screw rods, this screw rod end is provided with set screw nut, described limb is arcuate structure along its length, described limb comprises the inner that approaches fixed cover inner circumference and the outer end that approaches fixed cover excircle, and the thickness of limb is by the inner thickening outward.
As preferably, the thickness of described limb outer end is 1cm, and the thickness of limb the inner is 0.3cm.
As preferably, described in be arranged in fixed cover and the outer peripheral screw rod of mounting cover is made as 4, wherein 2 screw rod along continuous straight runs are located at left end and the right-hand member of fixed cover and mounting cover, other 2 screw rods are vertically located at the top and bottom of fixed cover and mounting cover.
As preferably, described limb is 10
In sum, the utlity model has following advantage: the blower fan of this setting is arranged to demountable structure by wind wheel, be conducive to clean to wind wheel, the dust and other impurities on wind wheel thoroughly can be removed totally, prevent from getting rusty, strengthen the using effect of blower fan, and while wherein having parts to occur damaging, can change, without changing whole wind wheel, save cost, screw rod is set and makes the structure of wind wheel more stable, be difficult for loosening; The thickness of limb, by the inner thickening outward, has been strengthened centrifugal force, makes the rotational speed of blower fan faster, and efficiency is higher, simultaneously the little burden that can not increase bearing of varied in thickness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
