Submersible mixer

Abstract

The invention discloses a submersible mixer and relates to the field of construction equipment. The submersible mixer comprises a motor and an impeller, wherein a trash rack is arranged between the motor and the impeller; a guide barrel is arranged outside the impeller; a motor winding is arranged above the motor; a mechanical seal is arranged on a body of the motor; a fastening nut is connected to the tail end of the motor; the motor is directly connected with the impeller through the trash rack; the motor is connected with a self-cleaning device; and the self-cleaning device is arranged in the guide barrel. The submersible mixer is compact in structure, convenient to use, small in size, light in weight, easy to operate and maintain, convenient and rapid to mount and long in service life, the self-cleaning device is arranged in the guide barrel, and sundries can be prevented from being wound and blocked.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a submersible mixer. Background technique [0002] In the process of sewage treatment using the clean sludge method, the clean sludge is continuously stirred by the mixer to make the anaerobic microorganisms fully contact with the matrix and improve the treatment effect. Most of the mixers currently used in China, the motor is placed on the buoy, and the water impeller is placed in the water. The distance between the motor and the water impeller is relatively large, and the water impeller must be driven by an extended transmission shaft or a coupling. The transmission is unreliable. For some deep anaerobic pools, there will be problems such as not being able to stir at the bottom, which affects the treatment effect. In addition, there are many parts, the blade sludge is difficult to handle, and the coordination relationship is complicated. Production, The maintenance and pr...

Most of the mixers currently used in China, the motor is placed on the buoy, and the water impeller is placed in the water. The distance between the motor and the water impeller is relatively large, and the water impeller must be driven by an extended transmission shaft or a coupling. The transmission is unreliable. For some deep anaerobic pools, there will be problems such as not being able to stir at the bottom, which will affect the treatment effect. In addition, there are many parts, the blade sludge is difficult to handle, and the coordination relationship is complicated. Production, Maintenance and processing costs are high, the machine is easily damaged, and the service life is short
