Embodiment Construction

[0011] An impeller of a spiral fan blade of an axial flow high-pressure fan. When in use, it is installed in the fan casing 4, the bearing 6 and the pulley 7 are fixed on the central rotating shaft 1, and the bearing 6 and the wind protection cover 3 pass through the bracket 5 Fixed on the field.

[0012] working principle

[0013] When the fan is powered to drive the belt pulley to rotate, the air is driven by the spiral fan blade and is discharged under high pressure from the air outlet 9, and then the air enters through the air inlet 8 and is discharged again. In this way, the work of the fan is completed repeatedly.

Abstract

The invention belongs to fan manufacturing technology field. The vane is produced into spiral type, its rotating centre is penetrated with a centre rotation shaft and is fixed; its external edge part and the inner wall of the wind protecting cover with cylinder type are sealed together. The fan with the structure is arranged in the fan shell, when the centre shaft begin to rotate, it drives the spiral vane and the wind protecting cover to rotate, the air sprays out high pressure air under the effect of the vane pushing force and the wind protecting cover, the air pressure is far larger than the eccentric fan with the same power. It can be widely applied to the air exchange in barn, the transmission of high pressure air in furnace, and other high power air transmission spots.

Description

technical field [0001] The invention relates to a high-pressure fan, in particular to an impeller of a helical blade of an axial-flow high-pressure fan. Background technique [0002] There are different structures of fans on the market, generally there are two types: axial flow type and centrifugal type. The axial flow fan has a large air volume, but the wind pressure is small; the centrifugal fan has a large pressure, a small air volume, and a low energy efficiency conversion rate. Industrial and mining enterprises urgently need fans with large air volume and high pressure, which is a blank in the fan industry. Contents of the invention [0003] The present invention is to provide an impeller of a helical fan blade of an axial-flow high-pressure fan. The fan equipped with this impeller has both the air volume of the axial flow fan and the pressure of the centrifugal fan, and has a high energy efficiency conversion rate. [0004] The technical solution for realizing the...
