The Technical Change Direction of the Double Shaft Wet Mixer

  At present, some companies have double shaft mixers, and ash storage is about 2000-3000 tons per day. Since put into production use, grey library mixer in the process of running, because the ash powder humidity is big, easy adsorption to the mixer compartments of the body wall, blade, spindle and solidified into blocks, the formation of ingot "cement", cause a large mixer resistance at run time, discharge difficult. More seriously, after adding water mixing wet dust adhesion in the blade, the drive shaft, to the body wall, dual-axis mixer current overload caused by motor, speed reducer damage and other accidents, seriously affect the safety in production run. In order to ensure the normal operation of the mixer, it can only be used to eliminate or knock the blade, spindle and box of the mixer manually, resulting in different damage to the equipment degree, which greatly increases the maintenance amount of the overhaul. Take turns to clean the blender every day, the manpower and material power consumption also brings the safety hazard.

  Above problems of our factory can transform humidification mixers, effect is particularly significant, such as two units of a certain power plant is 2x30 MW, mixer output of 300 tons/hour, discharge amount is 3000-4000 tons a day, two units of a certain power plant is 2 x 35 MK, mixer output of 200 tons/hour, a day capacity of 3500 tons, discharging in blender before modification in the process of discharging frequent motor overload, motor current between 50 to 60 a beating, causes the drive shaft bending, reducer damage for many times, and the blade wear basic monthly need to change, after more than a year of time drive shaft has not occurred bending deformation, maintain between 30 to 40 a current, deceleration machine, mixer, running stability. In addition, the cleaning frequency of the mixer is greatly reduced, which reduces the labor intensity, eliminates the security risks, increases the energy efficiency of the equipment, reduces the equipment loss, and saves the maintenance cost.
