Abstract
A centfifugal blowing machine set consists of a biaxial extension motor, two identical centrifugal blowing machines, an air inlet pipe, an air outlet pipe and a frame. The biaxial extension motor drives the simultaneous working of the two identical blowing machines, which makes the axial forces produced by the blowing machines cancelled out, thereby resolving the problem that prior centrifugal blowing machine is easy to be damaged, which is because that the axial forces cause the heating of the bearing.
Description
The utility model relates to a kind of centrifugal blower group
In wind-force conveying and dust pelletizing system, use centrifugal blower usually as power source.Require the also increase accordingly of air pressure of blower along with the increase of conveying material concentration, fed distance, transporting resistance.To be motor link by belt pulley or coupling and blower fan axle the kind of drive of existing blower.After blast increased, the axial force that fan bearing bore also increased thereupon, causes bearing running hot, and then caused damaging, and caused shutdown loss and increased maintenance expenses.
The purpose of this utility model is that a kind of centrifugal blower group will be provided, this device is stretched two centrifugal blowers of driven by motor by a twin shaft and is worked simultaneously, the axial force that blower is produced is cancelled out each other, thereby has solved the problem that existing centrifugal blower causes bearing heating to damage because of axial force.
The purpose of this utility model be achieved in that the centrifugal blower group by twin shaft stretch motor, two identical centrifugal blowers, air intake pipe, exhaust duct and frames are formed.Motor shaft respectively with the impeller direct connection of two blowers, with exhaust duct and air intake pipe two blowers are together in series.
Owing to adopt such scheme, overcome the deficiency of separate unit centrifugal blower.
Below in conjunction with embodiment's accompanying drawing the utility model is further specified.
Fig. 1: the plan view that is the utility model embodiment
Among the figure: 1 frame, 2 centrifugal blowers, 3 exhaust ducts, 4 twin shafts stretch motor,
5 air intake pipes, 6 centrifugal blowers.
In Fig. 1, the shaft extension that twin shaft is stretched motor 4 respectively with the impeller direct connection of centrifugal blower 2, centrifugal blower 6, one end of exhaust duct 3 connects with the exhaust port of centrifugal blower 2, and the other end connects with an end of air intake pipe 5, and the other end of air intake pipe 5 connects with the intake grill of centrifugal blower 6.Centrifugal blower 2, twin shaft are stretched motor 4, centrifugal blower 6 all is fixed on the frame 1.
Result of implementation shows: simple in structure, easy to install.
Claims (1)
1, a kind of centrifugal blower group, stretching motor 4, air intake pipe 5, centrifugal blower 6 by frame 1, centrifugal blower 2, exhaust duct 3, twin shaft forms, it is characterized in that: the shaft extension that twin shaft is stretched motor 4 respectively with the impeller direct connection of centrifugal blower 2, centrifugal blower 6, one end of exhaust duct 3 connects with the exhaust port of centrifugal blower 2, the other end connects with an end of air intake pipe 5, the other end of air intake pipe 5 connects with the intake grill of centrifugal blower 6, and twin shaft is stretched motor 4, centrifugal blower 2, centrifugal blower 6 and all is fixed on the frame 1.
