Submersible mixer: motor winding insulation level: F; protection class: IP68; working standard: S1;
Diving mixer uses
QJB series submersible mixer and QJT series submersible flow machine is based on the introduction of Swedish seal technology on Flygt submersible motor is developed successfully. After years of practice and exploration, has formed a mixed and low flow two series of products, because of its type, structure and test method on innovation, making the overall performance of the products has reached the level of similar foreign products.
The motor winding of submersible mixer is F grade insulation, protection grade is IP68. The system energy consumption can be greatly reduced by using the aeration system in the sewage plant, and the oxygen filling quantity is obviously improved, and the precipitation can be effectively prevented. According to the technological requirements, direct submersible stirring can be equipped with deflector.

Performance characteristics of QJB type submersible mixer
1, QJB type submersible mixer structure compact operation and maintenance is simple, easy installation and maintenance, long service life.
2, leavesThe wheel has the best hydraulic design structure, high working efficiency, swept blade has self-cleaning function can prevent sundries winding and blocking.
3, mixed with the aeration system can greatly reduce the energy consumption, the oxygen filling increased significantly, effectively prevent the precipitation.
4, the motor winding insulation level, IP68 protection, anti dewing device of motor selection of imported bearings and patented, make the motor work more safe and reliable.
5, two mechanical seal material for tungsten carbide tungsten carbide. All exposed fasteners are made of stainless steel.
Scope of application of QJB type submersible mixer
Mixer in the following conditions should be able to normally run continuously
1) the maximum medium temperature is not more than 40;
PH value of the medium in 5-9 between;
3) liquid density is not more than 1.15 kg / cubic meter;
4) long term diving operation, the depth of the dive is generally not more than 20m;
QJB type submersible mixer selection considerations
The selection of submersible mixer is a complicated job selection is correct or not directly affect the normal use of equipment, as the principle of selection is to make full play the function of stirring mixer in a suitable volume, can be used to determine the flow rate. According to the technological requirements of different sewage treatment plant, the optimum flow mixer should ensure that between 0.15~0.3m/s, if less than the velocity of 0.15m/s is not up to the push flow mixing effect, more than 0.3m/s of the velocity will affect the process and effect caused by waste. So the QJB is first determined using the mixer in the selection of places, such as: before the sewage tank, sludge pool, biochemical pool; followed by medium parameters, such as suspended solids content, viscosity, temperature, pH and water; shape and depth etc..
The required power of the submersible mixer is determined according to the volume size, the density of the mixing liquid and the depth of the mixing, and the use of one or more mixers according to the specific situation.
Installation system of QJB diving mixer
The special installation system of the submersible mixer can quickly install and remove the submersible mixer without discharging the sewage in the pool.
When H < 4 m deep pool is recommended to install the system i. The diving depth can be adjusted by diving mixer in vertical direction according to the need, but also around the guide rod rotation angle for the maximum plus or minus 60 degree lifting system base, supporting frame and the lower bracket and the pool in the horizontal plane is associated with surface adopt the expansion bolt, without holes.
When H > 4 meters deep pool recommended installation system II, be a concrete foundation at the bottom of the pool (or steel base). The lifting system base, rope fixed frame and the guide base and the pool was related to the junction with the expansion bolt hole, without reservation. Install the system with the guide wire rope replacement II guide rod, with convenient transportation, simple on-site installation etc.. This system avoids the transportation of guide rod bending deformation, and the normal use of the situation fundamentally, and to effectively improve the deep deep pool case, due to the installation error of the guide rod and lead to the normal phenomenon. It is more convenient and reliable to operate under the condition of the installation of the top of the cantilever pool (for example).
The customer ordering, please provide the deep pool and H pool type map, in order to determine the size of the guide rod or the guide wire processing factory. The material of the installation system is made of stainless steel (or carbon steel). Install the system in addition to the guide rod or the guide wire, lifting base, multi submersible mixer can share a set of lifting devices (users have special record except).
The special installation system of the QJB mixer can quickly install and remove the submersible mixer without discharging the sewage in the pool;
Installation system I only apply to the pool depth of the 4m, models for the QJB0.85/8-260/3-740C and QJB1.5/6-260/3-980C mixer, where I -1 can be adjusted in the horizontal and vertical direction;
The installation system II, III and IV, VI is suitable for the deep pool is larger than 4m, the guide rod in the horizontal direction along the guide rod axis of rotation, the maximum angle of -60 DEG ~+60 DEG when the pool depth greater than 4 meters, a supporting frame should be increased in the middle rod;
The supporting frame and the lower bracket and the lower bracket and the bottom of the tank are fixed with steel expansion bolts;
The installation system of the submersible mixer is made of stainless steel and carbon steel;
Schematic diagram of the installation of QJB submersible mixer
The guide rod or the guide wire should be horizontal and vertical, can be used a correction;
The hook in the lifting submersible mixer impeller, end is on the horizontal plane should be upward of 5 DEG -10 DEG
The chain hoist by adjusting the diving mixer along the guide rod or the guide wire under the sliding process, the lifting hook and the center of the submersible mixer in the same vertical line.
