Description
Technical field
The invention belongs to Fan Equipment, particularly a kind of centrifugal inclined axial-flow blower.
Background technique
The existing market fan is of a great variety, mainly contains centrifugal, axial fan, and the centrifugal fan volume is large, is provided with the eddy current volute, make air become centrifugal air-out from air inlet through hollow shaft, air inlet/outlet needs 90 degree to turn, so complex structure, lowers efficiency, cost is high, uses inconvenience, is difficult to transportation.Axial fan pressure is low, and efficient is low, and noise is large, and application is narrower.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the invention provides that a kind of pressure is high, efficient is high, air quantity is large, volume is little, and is easy to use, make simple, cost is low, the centrifugal inclined axial-flow blower that is easy to transport.
Technological scheme of the present invention is: a kind of centrifugal inclined axial-flow blower, comprise air intake cone 1, casing 2, impeller 3, anterior stator 4, bearing support 5, afterbody fixed plate 6, software Sealing 9, sealing flange 11, air intake cone baffle plate 12, fastening flange 16, described air intake cone 1 is with casing 2 bolts or be welded and fixed one, described bearing support 5 is fixedly installed on housing 2 inside center positions, it is characterized in that: be fixed with anterior stator 4 between described bearing support 5 outer covers and the housing 2, bearing support 5 front ends are provided with impeller 3, described impeller 3 comprises shroud 31, blade 32, hub disk 33, reel 34, described air intake cone 1 rear end is provided with sealing flange 11, sealing flange 11 is welded on the air intake cone 1, described air intake cone baffle plate 12 welds together with sealing flange 11, described software Sealing 9 is arranged between sealing flange 11 and the fastening flange 16, is fixed by bolts on the sealing flange 11.
Further, described bearing support 5 is motor.
Further, the blade 32 of described impeller 3 is obliquely installed.
Further, shroud 31 diameters of described impeller 3 are greater than hub disk 33 diameters.
Further, the hub disk 33 of described impeller 3 is set to arc.
Advantageous effect of the present invention is: this blower fan becomes axial flow by centrifugal oblique flow, and gas medium becomes axial streamlined flow without right-angled bend, has reduced eddy current, so efficient is high, pressure is high, reduce noise, easy to use.Because gas medium is made into axial flow by impeller by stator, has improved the pressure of blower fan, has strengthened air quantity.This blower fan has deducted the eddy current volute, has greatly reduced volume, the weight of blower fan, makes simply, has therefore reduced cost, is easy to transportation and installation.
