Description
technical field:
The utility model relates to field of ventilation equipment, particularly relates to a kind of without volute casing centrifugal blower fan.
background technique:
Existing centrifugal blower is provided with spiral case mostly, and spiral case can reduce loss during fluid flowing, improves pressure and the efficiency of centrifugal blower entirety.But generally all need larger casing with the centrifugal blower of spiral case, take up room large, and carry inconvenience.And existing without volute casing centrifugal blower fan owing to lacking the water conservancy diversion of spiral case, also exist blower fan efficiency and export out the low problem of hydrodynamic pressure.
summary of the invention:
The purpose of this utility model is to solve the problems of the prior art, provide that a kind of volume is little, gas flow large and easily carrying without spiral case flow-mixing blower fan.
In order to achieve the above object, the technical solution of the utility model is:
A kind of without volute casing centrifugal blower fan, comprise outer container, in described outer container, interior case is installed, in described outer container, also offer chamber; Described chamber interior is provided with motor, the machine shaft of described motor is installed with the first belt pulley; The rear surface of described interior case and described chamber intersection offers through hole, described through hole is installed with bearing, be provided with rotating shaft in described bearing, described rotating shaft is on the one end in described chamber and is installed with the second belt pulley; Described first belt pulley is connected by belt with the second belt pulley; One end that described rotating shaft is in described interior case inside is provided with impeller hub disk; Described impeller hub disk is provided with wind guiding blade, and described impeller hub disk is connected with impeller front disc; Described outer container offers intake grill and exhaust outlet, and described intake grill and exhaust outlet penetrate into described interior case inside always; Described impeller front disc is connected with described intake grill; The bottom of described outer container is provided with 4 wheels and 2 supporting frames.
All the other except rear surface of described interior case 5 walls are all closely connected with the wall of described outer container.
The inner top surface of described exhaust outlet both sides is provided with fluid director.
Described wheel is separately installed with on 4 angles of outer container bottom surface, and described wheel is universal wheels.
Support frame as described above is height-adjustable supporting frame, and support frame as described above is provided with adjusting knob.
The minimum constructive height of support frame as described above is less than the height of described wheel.
The beneficial effects of the utility model are: of the present utility model a kind of without volute casing centrifugal blower fan, motor and impeller are installed in outer container inside, reduce the volume of blower fan; By being arranged on the fluid director of exhaust outlet both sides, add the pressure of exhaust outlet fluid; The design of supporting frame and guide wheel, makes the carrying of blower fan convenient simultaneously.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the internal structure schematic diagram of Fig. 2.
embodiment:
Embodiment 1
One as Figure 1-3, without volute casing centrifugal blower fan, comprises outer container 1, is provided with interior case 2 in described outer container 1, also offers chamber 3 in described outer container 1; Described chamber 3 inside is provided with motor 4, and described outer container 1 inside is divided into interior case 2 and chamber 3, can avoid the impact of motor convection cell.The machine shaft of described motor 4 is installed with the first belt pulley 41; Described interior case 2 and the rear surface 21 of described chamber 3 intersection offer through hole 22, described through hole 22 is installed with bearing 23, be provided with rotating shaft 24 in described bearing 23, described rotating shaft 24 is on the one end in described chamber 3 and is installed with the second belt pulley 42; Described first belt pulley 41 is connected by belt 43 with the second belt pulley 42; Belt pulley 42 transmission has steadily, the advantage of low noise and low vibration, and has the function of overload protection, improves centrifugal blower Security in use.One end that described rotating shaft 24 is in described interior case 2 inside is provided with impeller hub disk 51; Described impeller hub disk 51 is provided with wind guiding blade 52, and described impeller hub disk 51 is connected with impeller front disc 5; Described outer container 1 offers intake grill 11 and exhaust outlet 12, and described intake grill 11 and exhaust outlet 12 penetrate into described interior case 2 inside always; Described impeller front disc 5 is connected with described intake grill 11; Described outer container 1 is also provided with 4 wheels 7 and 2 supporting frames 8.
All the other except rear surface 21 of described interior case 25 walls are all closely connected with the wall of described outer container 1.
The inner top surface of described exhaust outlet 12 both sides is provided with fluid director 6, and fluid director can guide direction of flow exhaust outlet 12, improves fan efficiency.
Described wheel 7 is separately installed with on 4 angles of outer container 1 bottom surface, and described wheel 7 is universal wheels.Universal wheels can roll towards any level angle, facilitates the carrying of centrifugal blower.
Support frame as described above 8 is height-adjustable supporting frame, support frame as described above 8 is provided with adjusting knob 81.The height of supporting frame 8 can be controlled by adjusting knob 81, when two supporting frames 8 are highly different, the direction of intake grill 11 and exhaust outlet 12 can also be changed.
The minimum constructive height of support frame as described above 8 is less than the height of described wheel 7.By described adjusting knob 81, the height that can be adjusted to supporting frame 8 is less than the height of wheel 7, and at this moment wheel 7 just plays the effect of movable support; When the height of supporting frame 8 is greater than the height of wheel 7, supporting frame 8 just plays the effect of fixed support.
