Problems solved by technology
During the operation of diving equipment, these fibers will be wound on the rotating mechanical seal, causing the mechanical seal to fail to work or even damaged
[0005] 2. Since there is always a certain gap between the impeller and the mechanical seal seat, some of the fibers in the sewage will inevitably enter the cavity of the mechanical seal seat and wrap around the mechanical seal, affecting the safe use of the mechanical seal

The invention provides a high-efficiency permanent-magnetic submersible agitator. The agitator comprises an impeller (1); a cutting device is arranged in the cavity of the wheel hub of the impeller (1); the cutting device is a rotary cutter (3) fixedly installed in the cavity of the wheel hub of the impeller (1); a flow guide body (2) with an opening at the top end is installed around the rotary cutter (3); and the side surface of the flow guide body (2) is provided with flow guide holes through which winding matter flows out after cutting is performed, wherein the winding matter flows into the flow guide body (2) through the opening located at the top end for circulation. The agitator provided by the invention adopts a high-efficiency permanent-magnet electromotor to realize energy conservation and consumption reduction, and has the cutting function, so that the agitator can quickly and repeatedly cut fiber materials entering cavities of the impeller and a mechanical seal seat, and thoroughly eliminates winding of mechanical sealing, thereby improving the service life of the submersible agitator. The cutting device provided by the invention is a detachable device, and therefore the cutting device can be replaced when the cutting device has failure.
Description
technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a high-efficiency permanent magnet submersible mixer. Background technique [0002] Submersible mixer is widely used in urban sewage and industrial wastewater treatment, and is the main equipment for sewage treatment. The motor of the submersible mixer is a three-phase asynchronous motor, which is continuously rated based on the continuous duty system (S1), and consumes a lot of energy. Therefore, improving the efficiency and power factor of the motor can achieve significant energy-saving effects. The permanent magnet motor has a lot of space and advantages in improving efficiency and power factor due to the permanent magnet excitation placed in the rotor core of the three-phase induction motor. . If the submersible mixer adopts a high-efficiency three-phase permanent magnet synchronous motor, it will play a great role in reducing the user's operati...
