Industrial Submersible Mixers Water and Wastewater Equipment

Submersible Mixers Description

Submersible mixer, also known as submersible propeller, is suitable for mixing suspended solids in sewage, thin slurry, industrial process liquids, etc. in the process of sewage treatment plants, creating water flow, strengthening the mixing function, and preventing sludge precipitation.

QJB type Submersible Mixer, a key equipment used in the water treatment technology, can meet the technological requirement for homogeneity and fluidity of solid-liquid two-phase flow and solid-liquid-gas three phase flow in biochemical course of the water treatment process. It is composed of the submersible motor, impeller, and installation system etc.. The submersible mixer is in direct connection structure. Comparing with the traditional high-power electric motor that retards speed by a speed reducer, it is highlighted by compact structure, low energy consumption, facile maintenance. The impeller shaped by finishing casting or punching, which has high precision, forceful thrust as well as simple, nice-looking and streamlined profiling. The series of products are applicable to the places that requires for solid- liquid agitating or mixing.

Submersible Mixers Parameter

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 highly-efficient shape of the propeller, which is directly connected with the submersible motor,provides a powerful jet of water.
The oil chamber incorporates an electrode type leakage sensor to detect for water intrusion into the chamber. (1.5kW and above)
Submersible mixers are available in wide variations. Lineups include models without a guide ring to improve the mixing effect while increasing water flow, models with a guide ring that provides an excellent flow regulating effect, and low-water level models that are applicable with a minimum operating water level of 500mm. The cast iron type or stainless steel casting type can be selected according to field applications.
The mixers can be used for either aerobic/aeration treatment that mixes water and air, or anaerobic treatment that does not mix air into the water.
When used in combination with lifting device (optional), the mixer can be easily inspected and serviced without entering the tank.

Submersible Mixers Application

For industrial wastewater treatment and tap water/sewage treatment
For environmental conservation in ponds and rivers
For artificial water flow in amusement facilities
For mixing, stirring, dissolving, density equalization and aeration

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.
