Rotary atomizer having electro-magnetic bearings and a permanent magnet rotar |
摘要 |
An improved rotary disc atomizer for use in, for example, spray dryers or congealers is disclosed. The rotary disc may be directly mounted to the shaft of a high-speed electrical motor. The high-speed electrical motor comprises a permanent magnet rotor and electro-magnetic bearings. The electro-magnetic bearings may be supported by one or more upper/lower bearing housings and used to enable frictionless support of the shaft/rotor and rotary disc. The atomizer system may further comprise a gas distributor enabled to dynamically adjust the velocity at which the gas leaves the radial vanes and meets with the atomized droplets. |

1. A rotary atomizer comprising:
an electric motor, said electric motor having a stator and a permanent magnet rotor, wherein said permanent magnet rotor is configured to output a rotational force; a shaft vertically installed, the shaft configured to be rotated by the rotational force; one or more magnetic bearings, said one or more magnetic bearings configured to provide frictionless radial and axial support to the shaft; a rotating disc installed at a lower end of the shaft, said rotating disc configured to spray liquid in the form of fine particles; and an air connector, wherein the air connector receives air to be diverted into one or more gaps between the shaft and the one or more magnetic bearings. |
