Abstract
The utility model belongs to a centrifugal impeller capable of changing the wind direction, which mainly consists of an upper impeller disc, a motor and a lower impeller disc, wherein a blade group arranged between the upper impeller disc and the lower impeller disc presents the shape of an inverted trapezoid, and blades which form the blade group also present the shapes of the inverted trapezoids; a motor shaft is connected with the lower impeller disc; the upper impeller disc is an arc-shaped ring sleeve, the bottom of the upper impeller disc is large, and the upper part of the upper impeller disc is small; a motor fixing disc is arranged on the motor; and an included angle between the oblique edge of each blade and the horizontal line is within 25 to 75 degrees. As the centrifugal impeller adopts the structure of a centrifugal ventilator, air flow which is blown out can flow basically along the direction of a wheel shaft. The centrifugal impeller has the advantages of simple structure, good using effect and long service life.
Description
Technical field
The utility model belongs to a kind of wind shifts centrifugal impeller.
Background technique
Traditional ventilator has two kinds of centrifugal and axial flow, and centrifugal fan borrows impeller to rotate in spiral case, and air is sucked from the impeller center, under centrifugal action, sends along the outlet of tangent direction.The impeller of axial fan has the blade of propeller-like, and blade promotes air when wheel rotation, makes it flow and produce the air-supply effect along wheel shaft (or claim radially, promptly parallel with motor shaft) direction.The air-flow that centrifugal fan blows out is straight and even, but the air-flow that blows out can not flow along the wheel axle direction.The air-flow rotation undulate that axial fan blows out is inhomogeneous, but the air-flow that blows out can flow along the wheel axle direction.The centrifugal fan that the air-flow that does not blow out at present flows along the wheel axle direction basically, for a change airflow direction needs to establish shell in the impeller outsourcing, thereby increases manufacture cost, and also using to the user makes troubles.
Summary of the invention
The purpose of this utility model is a kind of wind shifts centrifugal impeller of design, adopts the centrifugal fan structure, and the air-flow that blows out is flowed along the wheel axle direction basically, have simple in structure, the advantage of the good and life-span length of using effect.For this reason, the utility model mainly is made up of last wheel disc, motor and following wheel disc, and the vane group of the utility model between upper and lower wheel disc is trapezoidal, and the blade of forming vane group is trapezoidal.Described motor shaft is connected with following wheel disc.The described wheel disc of going up is to go up little arc ring set greatly in the end.Described motor is provided with the motor fixed tray.Described blade hypotenuse and horizontal angle are 25 °-75 °.Said structure has reached the purpose of this utility model.
The utility model adopts the centrifugal fan structure, need the air-flow that blow out be flowed basically along the wheel axle direction by shell, has simple in structurely, and the air-flow that blows out is straight and even, the advantage of the good and life-span length of using effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of bowing of the present utility model.
Specific embodiments
As depicted in figs. 1 and 2, a kind of wind shifts centrifugal impeller mainly is made up of last wheel disc 1, motor 6 and following wheel disc 3.Vane group between upper and lower wheel disc is trapezoidal, and the blade 2 of forming vane group is trapezoidal.Described motor shaft 4 is connected with following wheel disc.The described wheel disc of going up is to go up little arc ring set greatly in the end.Described motor is provided with motor fixed tray 5.Described blade hypotenuse and horizontal angle are 25 °-75 °.Hollow forms intake grill 7 between the upper and lower wheel disc.
The lower end that is down trapezoidal each blade is span and is fixed on down on the wheel disc periphery, each blade guarantees that at least a limit is a hypotenuse, the hypotenuse of each blade outwards is provided with, and makes vane group be trapezoidal, and the upper end of each blade is fixed on the corresponding last wheel disc that is provided with.Last wheel disc is to go up little arc ring set greatly in the end, is beneficial to the wind guiding, and last wheel disc middle part is an intake grill.For making things convenient for fixed electrical machinery on motor, to be provided with the motor fixed tray, can conveniently motor be fixed in the pipeline and equipment that needs exhausting.Thereby the utility model is fixed without spiral case or shell.
During use, motor drives the lower whorl disc spins by motor shaft, advances you and drives vane group and the rotation of last wheel disc, the rotating blades group produces negative pressure air is sucked from intake grill, under centrifugal action, inhaled air blows out through vane group, and the air-flow that blows out flows along the wheel axle direction basically.The utility model can be widely used in ventilation, dust discharge and the cooling of factory, mine, cooling tower, vehicle, boats and ships and building; The ventilation of boiler and industrial furnace and air inducing; Cooling in the apparatus of air conditioning and the domestic electric appliance and ventilation; The oven dry of cereal and selecting and recommending; The inflation of wind-tunnel wind regime Hovercraft and propelling etc. have wide range of applications.
In a word, the utility model adopts the centrifugal fan structure, and the air-flow that blows out is flowed along the wheel direction of principal axis basically, have simple in structure, the advantage of the good and life-span length of result of use.
