QJB type submersible mixer is a submerged equipment that works continuously under full immersion conditions and integrates the functions of mixing, mixing and pushing flow. It is suitable for various pools, such as oxidation ditch, anaerobic acidification pool, homogeneous pool, etc. It consists of underwater motor, reducer, stirring paddle and control system.
QJB type submersible mixer is a submerged equipment that works continuously under full immersion conditions and integrates the functions of mixing, mixing and pushing flow. It is suitable for various pools, such as oxidation ditch, anaerobic acidification pool, homogeneous pool, etc. It consists of underwater motor, reducer, stirring paddle and control system.
When the QJB type submersible mixer is working, the propeller is driven by the underwater motor and reducer to generate a high push flow to push the water body forward, improve the water flow conditions in the pool, obtain the flow rate required by the process, and effectively promote the mixed liquid. Uniform water quality and prevent sludge deposition, improve sewage treatment efficiency.
The QJB type submersible mixer is widely used in my country's sewage treatment plants. QJB type submersible mixer is divided into two series: mixing and stirring and low-speed pushing flow.
Whether the selection of the QJB type submersible mixer is correct or not directly affects the normal use of the mixing equipment. The main principle of selection is to allow the mixer to fully perform the mixing function in a suitable sewage tank. This standard can generally be determined by the flow rate.
In order to prevent the activated sludge in the sewage pool from depositing at the bottom of the pool and avoid the formation of "dead zones", the mixed liquid in the sewage pool must be kept at a flow rate of 0.3m/s. According to the different process requirements of the sewage treatment plant, the optimal flow rate of the QJB type submersible mixer should be guaranteed to be between 0.15 and 0.3m/s.
Therefore, before selecting the type, it is first necessary to determine where the QJB type submersible mixer is used, followed by the medium parameters, the shape of the pool, the water depth and even the installation method, etc. will have an impact on the selection, and energy saving factors should also be considered, because This will affect future operating costs.
