Submersible Mixers Description
Submersible mixers are suitable for promoting and stirring sewage containing suspended solids, thin mud, industrial process liquids, etc. in the process of sewage treatment plants, creating water flow, strengthening mixing function, and preventing sludge sedimentation. It is an important process in municipal and industrial sewage treatment processes. equipment. QJB type submersible mixer
At present, submersible mixers are widely used in sewage and wastewater treatment units of various environmental undertakings. They are suitable for stirring liquids containing suspended solids and solids, promoting water circulation and guiding water flow in nitrification, denitrification and phosphorus removal units. Main scope of application: sewage treatment plants, sludge tanks and aeration tanks, anaerobic or aerobic water, water containing rags, etc.; industrial processing, harsh environment, high requirements for operation, containing metal salts, pulp and fibrous substances water; industrial sewage treatment, containing some abrasive particles, rags and metal salts; mineral slurries with a high degree of abrasion; water flow generation in fisheries and sluices, oxygen supply, and environmental permitting substances; liquid fertilizers, containing grass, rope, Wood chips, etc.

Submersible Mixers Factor
- The maximum medium temperature does not exceed 40°C;
- The PH value of the medium is between 5-9;
- The density of the medium does not exceed 1150kg/m3;
- The diving depth is generally not more than 20m.
Submersible Mixers Features
The impeller has a suitable hydraulic design structure, high working efficiency, and the swept-back blade has a self-cleaning function to prevent debris from being entangled and blocked.
The insulation grade of the motor winding is F, and the protection grade is IP68. Imported bearings and motor anti-condensation devices are selected to make the motor work more reliable.
The submersible mixer has compact structure, simple operation and maintenance, convenient installation and maintenance, and long service life.
Mixed use with aeration system can greatly reduce energy consumption, significantly increase oxygenation, and effectively prevent precipitation.
Two mechanical seals are made of tungsten carbide-tungsten carbide. All exposed fasteners are stainless steel.

Energy-saving Submersible Mixers Selection
- The mixer must be submerged in water to work, and it cannot work in flammable and explosive environments or environments with strong corrosive liquids;
- Pool type;
- The characteristics of the medium include viscosity, density, solid content;
- The matching power required by the mixer is determined according to the size of the volume, the density, viscosity and mixing depth of the stirring liquid. One or more mixers should be used according to the specific situation.
