Product Description

Product Introduction
The QJB Submersible Mixer by Nanjing Lanling Environmental Technology Co., Ltd. offers two distinct series: mixed mixing and low-speed push current.
The mixing series mixers are expertly crafted for sewage treatment plants and industrial processes, ensuring effective mixing of liquids containing suspended solids.
The low-speed push-flow series mixers are perfect for industrial and urban wastewater treatment plant aeration tanks. They generate strong water flow with low tangential currents, making them ideal for circulation, nitrification, denitrification, and dephosphorization stages.
Use and Scope of Application:
The mixing and stirring series submersible mixers are designed to cater to various water treatment needs.
They ensure uniform mixing in processes requiring solid-liquid or solid-liquid-gas phase media interaction in industrial settings.
Introducing the QJB (T) Type Submersible Mixer:
* Ideal for sewage and wastewater/activated sludge mixing.
* Effective in controlling thickened sludge separation.
* Suitable for acid, alkali neutralization, and pH value adjustment processes.
* Prevents particles from coagulating and settling on the walls and bottom of pools.
* Enhances the efficiency of heat transfer systems.
Applicable in any setting where the separation of two or three phases is crucial. Our submersible mixers are built to operate seamlessly and continuously under the following conditions:
* The maximum medium temperature should not exceed 40ºC.
* The pH value of the medium should be between 5-9.
* The density of the medium should not exceed 1150Kg/m3.
* Suitable for long-term submersible operation, with a diving depth generally not exceeding 20 meters.
Warning!
The submersible mixer must be fully submerged in water to operate efficiently and safely. It is not designed for use in flammable, explosive, or highly corrosive environments!]Use and Scope of Application:
The mixing and stirring series submersible mixers are highly suitable for all kinds of water treatment processes.

Structural characteristics:
Mixing and stirring series products employ multi-pole motors with a direct-connected structure, ensuring low energy consumption and high efficiency. The impellers, created through precision casting or stamping, feature high precision, large thrust, and a sleek, compact design.
The low-speed push-flow series products utilize a cycloid pinwheel reducer, which offers low power consumption, low rotational speed, and a large impeller diameter, making them ideal for wide service areas. The impeller, crafted from polyurethane and aluminum alloy, ensures high strength and strong corrosion resistance, providing both mixing and flow-pushing capabilities while creating water flow.
The motor winding of the submersible mixer is class F insulated with an IP68 protection grade. Used in wastewater plant aeration systems, it can significantly reduce energy consumption, enhance oxygenation, and prevent sedimentation effectively. Depending on process requirements, it can be equipped with a deflector cover.

Installation system:

The specialized installation system allows for quick installation and removal of the submersible mixer without the need to discharge sewage from the pool.
Installation system
1
For pool depths less than 4 meters (H<4), the Qjb Stainless Steel Submersible Mixer is highly recommended. The adjustable diving depth of this mixer allows for vertical adjustment and a maximum rotational angle of ±60° around the guide bar in the horizontal plane. Installation is made easy as the lifting system's base, support frame, and lower bracket are all securely fastened with expansion bolts on the relevant pool connection surfaces, eliminating the need for pre-drilled holes.
For pool depths exceeding 4 meters (H>4), it is advisable to utilize the enhanced installation system.
2
For pools with depths greater than 4 meters, it is essential to construct a concrete foundation or steel structure base at the pool's bottom. The lifting system's base, rope fixing frame, and guiding base are secured with expansion bolts on the relevant connection surfaces, obviating the need for reserved holes. Installation System II replaces traditional guide rods with guide ropes, ensuring easy transportation and straightforward on-site installation. This method effectively mitigates issues related to guide rod bending or deformation during transport, which could impede normal system function. It also addresses potential installation errors, thereby guaranteeing reliable operation even in cantilevered pool tops, as shown in the accompanying illustration.
When placing an order, please specify the pool depth (H) and provide a pool type diagram. This information is crucial for the factory to determine the appropriate size for the guide rod or guide wire processing. The installation system is available in stainless steel or carbon steel. Notably, one lifting device can be shared among multiple mixers, except when special requirements are specified by the user.

Installation precautions:

*
Ensure the guide bar or guide wire is perfectly vertical. A lead hammer can be used for accurate alignment.
*
When lifting the submersible mixer with a hook, position the impeller end at an upward angle of 5°-10° relative to the horizontal plane.
*
Adjust the chain on the lifting device so that the lifting hook aligns with the submersible mixer's center of gravity, ensuring it slides down smoothly along the guide bar or guide wire.
