Description
Technical field
The utility model relates to a kind of indoor open air exhaust electric equipment, in particular for the ventilation equipment of the air-supply of cooling of air-conditioning, various air regenerating device and drying equipment, machine and various stoves etc.
Background technique
Existing ventilation equipment mainly is categorized as axial-flow blower and centrifugal blower.Axial-flow blower is exactly and the equidirectional air-flow of axle of fan blade (being the flow direction of wind and spool parallel), as electric fan, air-conditioning outer machine fan is exactly that the axial flow mode is moved blower fan, why be called " axial flow ", be can not change direction because of air by blower fan, but it is moving to be parallel to the blower fan axial flow, have characteristics such as simple in structure, solid and reliable, that noise is little, the function range of choice is wide.Centrifugal blower is the principle that is converted to potential energy according to kinetic energy, utilizes the impeller of high speed rotating that gas is quickened, and slows down, changes the flow direction then, makes kinetic energy convert potential energy to.In the one-stage centrifugal blower fan, gas is from axially entering impeller, and gas stream changes over radially when impeller, enters Diffuser then.In Diffuser, gas and changing flow direction cause deceleration, this decelerating effect converts kinetic energy to the pressure energy.Increased pressure mainly occurs in the impeller, and next occurs in the diffusion process.In the multistage centrifugal blower fan, make air-flow enter next impeller with return channel, produce more high pressure.Two kinds of blower fans of axial-flow blower and centrifugal blower all have its relatively distincter separately mechanical feature advantage, if both advantages characteristics in conjunction with utilization, will certainly reach better blower fan open air exhaust effect.
Summary of the invention
The utility model is attempted by the structural feature in conjunction with axial-flow blower and centrifugal blower, invents a kind of centrifugal propeller fan with two kinds of blower fan advantages characteristics.
The centrifugal propeller fan of the utility model is to realize purpose by following technological means:
Centrifugal propeller fan comprises body, motor cavity, diffusion guide blade, motor, centrifugal impeller, slip ring, modular construction such as airstream deflector and support constitutes, wherein body is a cylindrical shape entire body structure, open front is an intake grill, rear aperture is an exhaust outlet, motor cavity is positioned at internal body for the cylindrical shape seal structure, and be connected and fixed by diffusion guide blade between the body, motor is arranged at motor cavity inside, centrifugal impeller is positioned at the motor cavity front end, the centrifugal impeller diameter is identical with motor cavity cylindrical structure outer diameter, and there are the gap in centrifugal impeller and motor cavity, centrifugal impeller laterally is connected with motor, the front part of a body intake grill goes out to be provided with slip ring, slip ring is outside arc loudspeaker opening shape, and collar extension is fitted and connected and is fixed in intake grill, and the centrifugal impeller air sucking mouth is aimed at and entered to internal orifice, slip ring outer wall and internal body junction plane are provided with inside slope opening shape airstream deflector, and support is positioned at body outer wall bottom.
The beneficial effect of the centrifugal propeller fan of the utility model is by carrying out technological improvement for intake grill in original axial-flow blower structural feature and blade wheel structure, compact housing construction advantage of the cylindrical shape of retaining shaft flow fan and horizontal turnover wind characteristics, application by centrifugal impeller makes turnover wind produce pressure difference, reach the characteristic of centrifugal blower, and at intake grill slip ring to be set be that the air intake effect is more concentrated, the utilization of airstream deflector can make air enter can not produce in the body ill effect of turbulent flow vibrations, by the intake grill in original axial-flow blower structural feature and blade wheel structure being carried out technological improvement and the application by centrifugal impeller makes it have the advantageous properties separately of centrifugal blower and axial-flow blower.
