And connect the pulley gear of described motor and shaft.
The utility model changes mounting position of motor, make it independent installation, the combination of four dynamo-electric machine selective gear reductors is replaced with the combination that pulley gear joined by six grades of motors, vibration proof, reduce equipment cost, reduce the operation consumption of lubricating oil and mechanical seal, thus reduce the expense safeguarded and run, increase the service life.Six grades of motor speeds are about 960r/min, pulley gear gearratio got for four (gearratio is not more than 5), axle rotating speed is 960/4=240, meets the General Requirements (its rotating speed is 200 ~ 300r/min) of the side stir device rotating speed for wet desulphurization.Motor progression can be selected according to axle rotating speed and speed reducer drive ratio.
Therefore, as preferably, described motor is six grades of motors.Motor progression is high, and rotating speed is low, coordinates pulley gear, therefore agitator can be made to reach the rotating speed of technological requirement without the need to gear reduction unit, replaces the sub-assembly of harmonic series pot motor selective gear reductor.
As preferably, be also provided with the motor adjustment rack be fixed on described installation foundation, described motor is installed on this motor adjustment rack.
Further preferably, described motor adjustment rack comprises the motor mounting plate be connected with motor and the support bar being connected motor mounting plate and installation foundation, and described support bar is expansion link.
Further preferred, the face that described motor mounting plate is connected with motor is inclined plane, and angle of inclination is identical with the angle of inclination of described shaft.Namely parallel between the inclined plane of installing plate and the axis of shaft.
Motor adjustment rack adopts expansion link adjustment motor setting height(from bottom), simultaneously also adjustable belt connection angle, tightening belt, support motor weight.
As preferably, between described shaft with shaft support, rolling bearing is adopted to be connected.
Further preferably, the tower wall connecting place of described shaft and wet absorption tower adopts mechanical seal.
Installation foundation, adopts armored concrete to make, for motor and motor adjustment rack provide firm support, vibration proof; Motor adjustment rack, adjustment motor setting height(from bottom), adjustment belt connection angle tightening belt simultaneously, support motor weight; Six grades of motor progression are high, and rotating speed is low, coordinate pulley gear, agitator can be made to reach the rotating speed of technological requirement, replace the sub-assembly of harmonic series pot motor selective gear reductor; Pulley gear, connect motor and shaft, because adopting six grades of motors, motor speed is low, therefore can reach technological requirement without the need to gear reduction unit; Portable shaft support, is fixed on tower side wall, by roller bearings shaft, mechanical seal is utilized to prevent slurries from leaking, because making without the need to support motor this support become lightly easy, reduce equipment cost, and the mount vibration that causes due to motor rotation can be stopped; Stirrer paddle, adopts steel alloy material, drives slurries in tower to suspend and merges.
As preferably, the spacing between the installation site of described shaft support and installation foundation is 0.6m ~ 1.5m.
Compared with traditional side stir device, the utility model has following beneficial effect:
The utility model has vibration proof effect, cancel gear reduction unit, reduce equipment cost, reduce maintenance and the expense run, increase the service life, motor and shaft support are independently installed, belt is adopted to connect motor and shaft, guarantee shaft smooth running, can not motor rotation be subject to and the vibration effect that produces, select slow-revving six grades of motors to reduce gearratio, can gear reduction unit be cancelled, reduce equipment cost, reduce maintenance and the expense run, increase the service life.
