Duwan Environmental JBJ-500Tape-type agitator structure
JBJPropeller mixer structure and working principle:
Propeller mixer systems are a type of system that utilizes dosing mixers and reaction tanks.-The dosing stirrer is composed of a motor, a cycloidal gear reducer (with a set of cycloidal speed-reducing gears inside), a stirrer shaft, and stirrer blades. Once the motor is powered on, it drives the stirrer shaft and blades to rotate; the rotation of the dosing stirrer pushes the water flow within the reaction tank, ensuring that the chemicals and water are fully mixed and react, thereby shortening the mixing time of the chemicals with water and significantly enhancing the efficiency of the chemical usage.
Jiangsu Du'an Environmental Protection JBJ-500 FoldSlurry mixers consist of the working part (vertical mixing shaft, mixer), support part (bearing assembly, base), driving part (motor, reducer), and connecting accessories, etc.
The agitator drive unit is mounted at the top of the reaction tank, with the motor and reducer connected via flanges for easy installation and maintenance.
The motor is designed for outdoor use, with an insulation grade.FIP ratingIP55。

1.Each mixer is equipped with a reducer, the reducer usesK-H-VA novel transmission mechanism combining planetary transmission principles with short-radius involute gears, featuring robust load-bearing capacity, high reduction ratio, high transmission efficiency, compact size, low noise, and extended service life. The reducer can operate continuously within a specific operating range.
2.All transmission components of the reducer have been strictly treated, precisely machined, polished, well-contacted, and lubricated, ensuring smooth operation, low noise, and no additional axial force on both the output and input shafts, with a long service life.
3Electric motors, cycloidal gears, and all bearings are easy to replace and oiling systems are convenient for maintenance. Lifting lugs are mounted on the reducer.
4All supporting bearings are anti-wear spherical or cylindrical bearings. The service life of all anti-wear bearings in the reducer reaches50,000Hours above.
5Bearings exposed outside the reducer are lubricated with grease, adjusted and sealed with grease during installation. Other bearings and cycloidal gears are continuously lubricated with oil cups or oil pumps.
6The reducer features an anti-leakage oil seal and is controlled by an oil gauge to maintain the normal oil level.
7To bear the weight of the drive shaft and impeller, and to prevent shaft deflection due to load action during operation, as well as to prevent gear misalignment when the mixer is running, the output shaft of the reducer has sufficient size and rigidity.
（2Screw type agitator drive shaft
1The drive shaft is made of carbon steel pipe. After manufacturing, it undergoes annealing treatment. The propeller-type mixer drive shaft is a cantilever shaft and does not use a bottom-mounted bearing. The shaft surface is free of any defects or impurities to eliminate their impact on the shaft's fatigue strength and corrosion resistance. The shaft's linearity, verticality, and accuracy are precise, with an allowable deviation of... per meter of shaft length.1mm。
2．The blade slots of the moving shaft impeller should be designed considering the vertical movement of the impeller, with a small spacing of150mmThe impeller's movement does not affect other devices.
3Stainless steel shaft for mixerDType shell coupling connected to the output shaft, with full alignment.
4The drive shaft design does not incorporate a stabilizer; its operating speed is limited to:*Tuned vibration frequency65Within %. The calculations for critical speed, torque, and bending force take full consideration of the blade and shaft's mass and inertia.
