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

Embodiment Construction

[0028] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0029] The following description is merely exemplary in nature and not intended to limit the disclosure, application or use. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0030] like figure 1 As shown, the high-efficiency permanent magnet submersible mixer with anti-winding function includes impeller 1, mechanical seal 2, mechanical seal seat 3, bearing seat 4, high-efficiency permanent magnet submersible motor 5, bearing 6, and sliding sleeve 7. The main feature of the present invention is that the submersible mixer adopts a high-efficiency permanent magnet submersible motor, and the cooperation between the impeller 1 and the mechanical seal seat 3 is designed as a triple anti-winding structure. Firstly, a conical drain ring 31 is set outside the mechanical ...

Abstract

The invention discloses an efficient permanent-magnet submersible mixer with an anti-winding function. The efficient permanent-magnet submersible mixer comprises an impeller (1) and a mechanical seal seat (3), wherein the impeller (1) and the mechanical seal seat (3) are in clearance fit; a sharing pair is formed in the matched position of the impeller (1) and the mechanical seal seat (3) and is formed through matching of an annular rotary knife (13) on a hub (12) of the impeller (1) and a fixed knife (35) on the inner circumference of the mechanical seal seat (3). According to the efficient permanent-magnet submersible mixer with the anti-winding function, fiber-like substances in sewage can be prevented from entering a cavity between the mechanical seal seat and the impeller while energy is saved and consumption is reduced, winding of mechanism seal is thoroughly eliminated, and accordingly, the service life of the submersible mixer is prolonged.

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 with an anti-winding function. 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 based on the continuous duty system (S1) and has a large energy consumption. 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 th...
