structure
The QJB submersible mixer mainly consists of a submersible mixer host, installation system, and electrical control equipment.
Submersible mixers are divided into hybrid submersible mixers and low-speed push flow mixers according to their functions. Hybrid submersible mixers are divided into direct coupled stamping submersible mixers and non direct coupled submersible mixers according to their structural characteristics. The low-speed push flow submersible mixer belongs to the non direct coupled submersible mixer.
Hybrid submersible mixers are divided into casting mixers and stamping mixers according to their blade forming methods. The blades (impellers) of the casting mixer are formed by casting, and the material of the body shell is generally cast iron. The blades of the stamping mixer are formed by stamping, and the material of the body shell is generally stainless steel.
Hybrid submersible mixers are generally equipped with flow deflectors to increase axial flow and reduce radial flow, reduce impeller vibration, and increase operational stability. However, low-speed push flow submersible mixers are not equipped with flow deflectors.Product Introduction

The QJB series submersible mixer and QJT series submersible thruster are independently developed based on the sealing technology of German submersible motors. After years of practical exploration, two major series of products have been formed: mixed mixing and low-speed push flow. Due to their innovation in form, structure, and testing methods, the overall performance of this product has reached the level of similar foreign products.
structural characteristics

The mixed mixing series products use multi-stage motors and adopt a direct connection structure, which has low energy consumption and high efficiency; The impeller is formed by precision casting or stamping, with high precision, large thrust, beautiful and smooth appearance, and compact structure.
The low-speed thrust series products adopt cycloidal pinwheel reducers, equipped with low power, low speed, large impeller diameter, and wide service area. The impeller is made of polyurethane material and aluminum alloy, with high strength and strong corrosion resistance. In addition to its stirring function, it also has the functions of pushing and creating water flow.
The motor winding of the submersible mixer is F-class insulated and has a protection level of IP68. When used in conjunction with the aeration system in sewage treatment plants, it can greatly reduce energy consumption and significantly increase oxygen filling, effectively preventing sedimentation. According to the process requirements, the direct coupled submersible mixer can be equipped with a guide cover.

Purpose and Applicable Conditions

The mixing and stirring series submersible mixer is suitable for various water treatment processes and industrial enterprises that need to maintain uniform mixing and reaction of solid and liquid two-phase or solid, liquid, and gas three-phase media.
Mixing of sewage (wastewater)/activated sludge
■ Control the separation of concentrated sludge
Acid alkali neutralization and pH adjustment process
Prevent particles from condensing and settling on the pool walls and bottom
Improve the efficiency of the heat transfer system
Other places where it is necessary to maintain the separation of two or three phases

The submersible mixer can operate continuously and normally under the following conditions
High medium temperature not exceeding 42 ℃;
The pH value of the medium is between 5-9;
The medium density shall not exceed 1150Kg/m3;
Long term diving operation, with a diving depth generally not exceeding 20M.

If there are special requirements, please obtain them from our company.

Selection precautions
To ensure optimal operation of the submersible mixer, please provide the following information to the user:;
Purpose of application;
◎ Pool type and size, including water depth;
The characteristics of the stirring medium include pH value, viscosity, density, temperature, and solid content.
Install the system
The installation system of the submersible mixer can quickly install and disassemble the submersible mixer without the need to discharge sewage from the pool.
When the pool depth H is less than 4 meters, it is recommended to use installation system I. The diving depth of the submersible mixer can be adjusted vertically as needed, and the lifting system base, support frame, and lower bracket, which can rotate around the guide rod at a large angle of ± 60 ° in the horizontal plane, are all fixed with expansion bolts at the associated interface with the pool, without the need for reserved holes.
When the pool depth H is greater than 4 meters, it is recommended to use installation system II, which requires a concrete foundation (or steel structure base) to be built at the bottom of the pool. The lifting system base, steel rope fixing frame, and guide base are all fixed with expansion bolts at the associated interface with the pool, without the need for reserved holes. The installation system II uses a guiding steel rope guide rod, which has the characteristics of convenient transportation and simple on-site installation. This system fundamentally avoids the situation of guide rod bending and deformation caused by transportation, which affects normal use, and effectively improves the phenomenon of inability to lift due to installation errors of guide rods when the pool is too deep. Under the installation conditions with a cantilevered pool roof (as shown in the picture), it appears more convenient and reliable to operate.
When the customer places an order, please provide the pool depth H and pool type diagram so that the factory can determine the size of the guide rod or guide wire during processing. The material of the installation system is made of stainless steel (or carbon steel). In addition to guide rods or guide wires, and lifting bases, multiple mixers can share a set of lifting devices in the installation system (except for special user requirements).
Installation precautions:
The guide rod or guide wire should be perpendicular to the horizontal and can be calibrated with a lead hammer;
When lifting a submersible mixer, the lifting hook should tilt the impeller end 5 ° -10 ° above the horizontal plane
By adjusting the chain on the lifting device, the lifting hook and the lifting center of gravity of the submersible mixer are on the same vertical line during the sliding process of the submersible mixer along the guide rod or guide wire.
