Submersible mixer

QJB Type Submersible Mixing Pumps

Purpose:

The QJB model submerged mixer is divided into two main series: mixing and low-speed flow propulsion.

The Mixed Series Agitators are suitable for mixing suspended liquid in wastewater treatment plants and industrial processes.

Low-speed Turbulator Series Mixers are suitable for industrial and urban wastewater treatment plant aeration tanks, generating strong water currents with low tangential flow, which can be used to create water currents for circulation and stages such as nitrification, denitrification, and phosphorus removal.

Application Scope:

The blender should be able to operate continuously under the following conditions:

1. Maximum medium temperature does not exceed 40°C.

The pH value of the 2 medium ranges between 5~9.

3 Liquid density not exceeding 1150kg/m³；

4 Long-term diving operation, diving depth generally does not exceed 20m。

Performance Features:

Tightly structured, easy to operate and maintain, convenient for installation and maintenance, and with a long service life.

The impeller features an excellent hydraulic design structure, offering high work efficiency. The swept-back blades have an auto-cleaning function, preventing debris entanglement and blockage.

Combining with an aeration system can significantly reduce energy consumption, improve oxygenation levels, and effectively prevent sedimentation.

4 Motor winding insulation grade F, protection grade IP68, selected bearings and motor anti-condensation devices for safer motor operation.

5 double mechanical seals;

Model Representation Method:

!!! The blender must be fully submerged in water during operation and cannot be used in environments prone to flammability, explosiveness, or strong corrosive liquids!!!

Performance Parameters:

The mixer operates at a rated voltage of 380V and a frequency of 50Hz.zWound with F-grade insulation, IP68 protection rating, under operating mode I conditions.

Selection Considerations:

Selecting the right submersible mixer is a complex task, as its correctness directly affects the normal operation of the equipment. The principle of selection is to ensure that the mixer performs full mixing functions within an appropriate volume, typically determined by flow rate. According to the different process requirements of wastewater treatment plants, the optimal flow rate for the mixer should be between 0.15~0.3 m/s. Flow rates below 0.15 m/s fail to achieve proper push-mixing effects, while rates above 0.3 m/s can affect the process efficiency and lead to waste. Therefore, before selecting, first determine the application site of the submersible mixer, such as: wastewater pond, sludge pond, biochemical pond; followed by medium parameters like: suspended solids content, viscosity, temperature, pH value; and also the shape and depth of the pond.

The required matching power for the mixer is determined by the volume size, the density of the mixing liquid, and the mixing depth, with a single or multiple mixers used based on the specific circumstances.***For selection-related inquiries, please contact the supplier***
