Abstract
A blower special for supercharging, ventilating and exhausting mainly comprises a shell 2, a motor 6 arranged in the shell, a hub 4, blades 3 and the like, and is characterized in that the hub is of a conical structure, the inclination alpha of the conical surface of the hub and the axial direction of the hub is 20-40 degrees, and the blades are arranged on the conical surface of the hub. The utility model discloses a to wheel hub's circular conical surface design, have the outstanding advantage that pressure is higher than axial fan, the amount of wind is big than centrifugal fan, and the quality is light, small, the energy consumption is economized, the noise is low, the installation and maintain the convenience, be applicable to the ventilation among the complicated ventilation system and air exhaust.
Description
The utility model relates to a kind of structural design of pressurizating ventilation air draft special fan, belongs to the field of force ventilation air draft technology.
Mostly adopt the common centrifugal fan of mesolow in the existing machinery ventilation exhaust equipment, because of the defective on its structural design, when being applied in main equipment and the complicated ventilation exhaust system, be difficult to realize comparatively ideal effect at aspects such as pressure, energy consumption, rigidity, noise, equipment investments.
The novel blower fan of premium properties such as the purpose of this utility model provides a kind of reasonable in design, and it is higher to have pressure, and energy consumption is economized, noise is lower, firm in structure.
The utility model is a pressurizating ventilation air draft special fan, mainly by housing 2, place the motor 6 in the housing, formations such as wheel hub 4 and blade 3, it is characterized in that described wheel hub is a conical structure, the gradient α of its conical surface and wheel hub axial line is 20～40 °, and described blade places on the wheel hub taper seat.The utility model also can be provided with the stator 5 that links to each other with inner walls outside motor; In housing, also current collector 1 can be set.
The utility model makes wheel hub and blade be meridian and quickens to be connected by the taper seat design to wheel hub, has broken through the traditional cylindrical project organization of wheel hub, has pressure than the axial flow blower height, the outstanding advantage that air quantity is big than centrifugal blower, and light weight, volume is little, the saving energy, and noise is low, installation and easy to maintenance, through practical application, compare with existing mesolow centrifugal blower, but saves energy about 30%, reduce noise 5～8db (A), save capital construction investment about 40%.The utility model is applicable to ventilation and the air draft in the complicated ventilating system of integrated mills such as senior civil buildings such as hotel, assembly hall, sports equipment and automobile, motorcycle manufacturing, pharmacy, petrochemical industry, food, light textile.
Accompanying drawing has provided structural representation of the present utility model:
Fig. 1 is side structure of the present utility model and partial sectional view;
Fig. 2 is a Facad structure schematic diagram of the present utility model.
Below in conjunction with embodiment the utility model is further described:
The utility model places the motor 6 in the housing mainly by housing 2,3,5～13 stators 5 of 4,6～12 blades of conical wheel hub, and current collector 1 formation such as grade, wheel hub places on the machine shaft, adopts the integral die moulding, and its conical surface gradient α is 20～40 °; 6～12 blades evenly are arranged on the taper seat of wheel hub, and are meridian acceleration connection; The outer surface of current collector 1 is substantially parallel with the wheel hub conical surface, and with being used of stator, bootable inlet air flow is along axial flow, to reach best ventilation air draft effect.During use, starter motor 6 makes wheel hub 4 drive blade 3 rotations, and air-flow direction shown in the arrow in Fig. 1 enters housing, and by the turning effort of blade, passage and stator between the current collector 1 and the wheel hub conical surface discharge.
Claims (3)
1, a kind of pressurizating ventilation air draft special fan, by housing (2), place the motor (6) in the housing, wheel hub (4) and blade (3) constitute, it is characterized in that described wheel hub is a conical structure, the gradient α of its conical surface and wheel hub axial line is 20～40 °, and described blade places on the wheel hub taper seat.
