Problems solved by technology

The traditional asynchronous motor is inconvenient to adjust and generates a lot of heat, while the permanent magnet structure can realize stepless speed regulation
Generally, a stirring mechanism puts a stirring shaft underwater, and a motor is fixed above the water surface to drive the stirring shaft. For large-scale aquaculture, this kind of stirring mechanism is inconvenient to fix and use.

Abstract

The invention relates to a permanent magnet outer rotor aerator which comprises a stirring piece and a suspension piece. The stirring piece is connected with and arranged in a water area below the suspension piece; an impeller is assembled at the bottom of the stirring piece; a motor is arranged in the stirring piece in a sealing manner; the motor drives the impeller to stir water; the suspensionpiece realizes a stable operation posture in water by utilizing a floating ball which is unfolded in a central symmetry manner; and the floating ball adopts a double-layer structure, and a buoyancy block is arranged at the interlayer, so that semi-inflatable launching can be realized, the shore volume of the permanent magnet outer rotor aerator is effectively controlled, and the carrying difficulty is reduced.

Description

technical field [0001] The invention relates to the field of aerators, in particular to a permanent magnet outer rotor aerator. Background technique [0002] The traditional aerator generally adopts an asynchronous motor, and then is equipped with a gearbox. Because the mechanical structure is complex, the sealing performance is limited, and it is prone to oil leakage from the gearbox. In addition, the moment of inertia of the inner rotor structure is small, and it is more energy-saving to purchase the outer rotor. The traditional asynchronous motor is inconvenient to adjust and generates a lot of heat, while the permanent magnet structure can realize stepless speed regulation. The general stirring mechanism all is to put a stirring shaft under water, and a motor is fixed above the water surface to drive the stirring shaft. For large-scale aquaculture, this type of stirring mechanism is inconvenient to fix and use. Therefore, it is necessary to invent a permanent magnet e...
