Description
Technical field:
The utility model relates to the technical field of centrifugal blower, more specifically to a kind of power frequency centrifugal blower.
Background technique:
Existing blower fan is generally divided into two kinds of centrifugal blower and axial-flow blowers, centrifugal blower is the mechanical energy that relies on input, improve supply gas the side by side mechanical device of body of gas pressure, it is widely used in ventilation, the dust discharge and cooling of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building.Existing centrifugal blower is generally provided with spiral case, and motor is arranged on spiral case, and spiral case is arranged on ventilation equipment again, thereby the support of motor is provided by spiral case entirely.
And power frequency centrifugal blower is to instigate the centrifugal blower that adopts industrial ac frequency, its industrial environmental influence is larger, for guaranteeing that centrifugal blower has longer working life, generally need the spiral case of centrifugal blower to there is larger intensity, and be to increase spiral case intensity generally to adopt the yield strength that increases spiral case thickness or increase spiral case material, but the yield strength that increases spiral case thickness and still increase spiral case material has all increased the moulding difficulty of spiral case, has indirectly improved cost of production.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of power frequency centrifugal blower, the intensity that it is simple in structure, to have increasing.
Technology solution of the present utility model is as follows:
A kind of power frequency centrifugal blower, comprise spiral case, motor and impeller, motor is fixed on spiral case by bolt assembly, spiral case is comprised of the panel of housing and housing both sides, panel is welded on housing, on housing, form some roads to the conduit of hull outside bending, in conduit, paste and be fixed with sound-absorbing sponge strip, on described motor, be fixedly connected with mounting base.
On the panel of described spiral case, form slotted eye, on a panel, be fixedly connected with motor, the main shaft of motor is fixedly connected with impeller, the slotted eye of described motor cover plate through the slotted eye of panel; The slotted eye of another panel has been bolted to connection protection net.
Described conduit is evenly distributed on the housing of spiral case, and the inner side surface of sound-absorbing sponge strip and the inner side surface of housing in conduit flush.
The air opening end of described spiral case is welded with three-back-shaped side plate, forms several bolt through-holes on side plate.
The bottom surface of described mounting base, lower than the least significant end of spiral case, forms several bolt through-holes in mounting base.
The beneficial effects of the utility model are:
1, mounting base on the motor of its centrifugal blower, the support of motor is provided by base, thus motor is little to the active force of spiral case, and spiral case, without larger wall thickness or higher yield strength, provides cost savings.
2, the spiral case that it adopts is Split type welding moulding, compares global formation easily manufactured, sets up the intensity that conduit can increase spiral case simultaneously on spiral case.
3, it installs sound-absorbing sponge in the conduit of spiral case, when affecting the normal operation of blower fan, has effectively reduced noise.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the angle structural representation that changes of the present utility model;
Fig. 3 is the angle structural representation that changes of the present utility model.
In figure: 1, spiral case; 2, motor; 3, impeller; 4, mounting base; 5, sound-absorbing sponge strip; 6, protection net; 11, panel; 12, housing; 13, side plate; 111, slotted eye; 121, conduit.
Embodiment:
Embodiment: see shown in Fig. 1,2,3, a kind of power frequency centrifugal blower, comprise spiral case 1, motor 2 and impeller 3, motor 2 is fixed on spiral case 1 by bolt assembly, spiral case 1 is comprised of the panel 11 of housing 12 and housing 12 both sides, and panel 11 is welded on housing 12, forms some roads to the conduit 121 of housing 12 outer lateral bucklings on housing 12, the interior stickup of conduit 121 is fixed with sound-absorbing sponge strip 5, on described motor 2, is fixedly connected with mounting base 4.
On the panel 11 of described spiral case 1, form on slotted eye 111, one panels 11 and be fixedly connected with motor 2, the main shaft of motor 2 is fixedly connected with impeller 3, the slotted eye 111 of described motor 2 cover plates 11 through the slotted eye 111 of panel 11; The slotted eye 111 of another panel 11 has been bolted to connection protection net 6.
Described conduit 121 is evenly distributed on the housing 12 of spiral case 1, and the inner side surface of the sound-absorbing sponge strip 5 in conduit 121 and the inner side surface of housing 12 flush.
The air opening end of described spiral case 1 is welded with three-back-shaped side plate 13, forms several bolt through-holes on side plate 13.
The bottom surface of described mounting base 4, lower than the least significant end of spiral case 1, forms several bolt through-holes in mounting base 4.
Working principle: this practical motor 2 is arranged in mounting base 4, spiral case 1 is arranged on motor 2, its motor 2 supports and is provided by mounting base 4, thereby the active forces such as gravity of motor 2 do not act on spiral case 1, thereby the intensity of spiral case 1 does not need very high, thereby, without larger wall thickness or higher yield strength, provide cost savings.Its spiral case adopting 1, for panel 11 and housing 12 welding fabrications, is compared global formation easily manufactured simultaneously, and set up conduit 121 on the housing 12 of spiral case 1, increases the intensity of spiral case as muscle; And in the interior installation sound-absorbing of conduit 121 sponge, when affecting the normal operation of blower fan, effectively reduced noise.
