However, in actual construction, it is difficult to ensure that the machine seal and the bearing can be replaced each time under the condition that a machine unit is stopped or slurry in the absorption tower is discharged completely, namely, constructors cannot enter the absorption tower, and only parts can be replaced outside the absorption tower. In the replacement process, the power connection of the stirring shaft is required to be removed firstly, so that one end of the stirring shaft outside the absorption tower is suspended, and then the damaged machine seal and bearing are axially pulled out from the stirring shaft. In the process, as the stirring fan blades are positioned at a certain depth in the absorption tower and are fixedly provided with the stirring fan blades, the outer end of the stirring shaft is suspended, the length of the stirring shaft is short, and finally, the mechanical seal and the bearing which are rotationally connected with the shell of the absorption tower are removed and replaced, and at the moment, the stirring shaft loses radial support and is inclined in the shaft hole.
At the moment, after a new mechanical seal and a new bearing are sleeved on the stirring shaft, the shaft center of the stirring shaft is difficult to position by constructors due to the lever principle and the large dead weight of the stirring shaft at one end of the stirring blade.
Therefore, how to perform temporary axis positioning on the mixer shaft when detaching the defective machine seal and the bearing is convenient for the installation of the machine seal and the bearing after the replacement, which is a technical problem to be solved by the person in the field.
