The Jiangsu Du'an Environmental Protection QJB Submerged Impeller is suitable for industrial and urban wastewater treatment plant aeration tanks and anaerobic tanks. It can create water flow in the pool for water circulation, nitrification, denitrification, and phosphorus removal stages.
Submersible mixers are equipped with multi-pole motors and feature a direct-drive structure, offering low energy consumption and high efficiency. The impellers are precision cast or stamp formed, ensuring high accuracy, strong thrust, an aesthetically pleasing and smooth appearance, and a compact structure.
The motor windings of the submersible mixer are insulated to F-grade, with a protection rating of IP68. When used in conjunction with the aeration system in a wastewater treatment plant, it significantly reduces system energy consumption and significantly improves oxygenation, effectively preventing sedimentation. According to process requirements, the direct-drive submersible mixer can be equipped with a flow guide hood.
Submersible mixer flow inducer and aeration machine mechanical seal material, requirements, and structure:
Submersible mixers, submersible flow diverters, and submersible aeration machine mechanical seals are generally made of tungsten carbide, which is divided into the dynamic ring and the static ring.
Submersible mixers, submersible propellers, and submersible aeration pumps are equipped with submersible motors featuring bidirectional mechanical seal structures, with up to two seals to ensure safe operation. The mechanical seals of the submersible motors perform well with no leakage, and the insulation grade should comply with F-class specifications. The internal pressure of the mechanical seals within the submersible mixers, propellers, and aeration pumps can withstand a pressure of 0.2MPa for 10 minutes without leakage.

The QJB Submersible Mixers are designed for wastewater treatment plant processes, advancing the mixing of suspended wastewater, thin sludge, industrial process liquids, etc., to create water currents, enhance mixing functions, and prevent sludge sedimentation. They are crucial equipment in municipal and industrial wastewater treatment processes, and are categorized into Submersible Mixing Mixers and Low-Speed Submersible Thruster Mixers.
Submersible mixers are currently being used in some ponds to adjust and mix the medium within, preventing it from settling. When it comes to mixing equipment, we actually encountered simple mixers in high school, during chemistry class, where teachers used stirrers, filter paper, funnels, and glass cups to create a basic mixing device. This is also a crucial mixing equipment, as such simple setups are the foundation for the development of mixing machinery. The mixing equipment used on construction sites today has also evolved from these basic mixing devices.
With the addition of certain auxiliary equipment, the use of large-scale mixing equipment has been achieved. Currently, whether it's cement mixers used on construction sites or submersible mixers in wastewater treatment plants, they are essentially just the evolution of tools like filter paper and mixing rods. One could say this is merely the early form of mixers. The only difference is that instead of filter paper, membranes are used for mixing, and instead of mixing rods, impellers are employed, leading to the formation of large-scale mixing machinery. This type of submersible mixing equipment is also a typical piece of equipment today, known for its ability to clean certain impurities in wastewater.
