Submersible Mixers Description

The submersible mixer shall be liftable and lowered, and shall be easily removed for inspection or service without the need for personnel to enter the tank or well.
The agitator shall have a sliding guide rod bracket as an integral part of it, the entire weight of the agitator shall be loaded on a bracket which must be able to withstand all thrust caused by the agitator. The agitator, its accessories and cables, shall be capable of continuous submersion under water to a maximum depth of 20 meters without loss of watertightness.

The use of propellers for hydraulic circulation is an efficient and energy-saving means, especially widely used in anaerobic ponds, anoxic ponds and oxidation ditch in sewage biochemical treatment. Since only the necessary circulation and flow rate need to be provided in this type of pond, the mixed liquid in the pond can be kept in a suspended state, so that the microorganisms can be fully contacted with their substrates, so the pond shape mostly adopts the shape of an oxidation ditch, and the energy input through the propeller, A continuous circulating water flow is formed. This design can not only effectively maintain the suspension of the mixed liquid, but also because the flow rate of the circulating water flow in the pool is usually dozens or even hundreds of times higher than the flow rate of the influent water, so that the flow in the pool has a huge dilution and homogenization ability, thus making the process resistant to impact. load characteristics. Also in the design of the oxidation ditch, the surface exposure equipment has the dual functions of oxygenation and hydraulic circulation. In engineering, when it is often necessary to adjust the oxygenation capacity due to changes in water quality and water volume, it is difficult to take into account the circulating flow rate in the pool, resulting in the problem of sludge deposition in the ditch. Carrying out this technological transformation is not complicated, and the investment is very small.

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.
