Description

Technical Field

[0002] Fixed rotary soot blower is a device used to clean dust and impurities accumulated in industrial equipment. It is mainly used in the dust blowing environment of the heating surface with low temperature. Its working principle is to drive the soot blowing pipe fixed in the heating surface to rotate and blow through the motor to generate high-speed airflow to flush away impurities.

[0003] When using a fixed rotary sootblower to perform dust removal operations on some equipment, the fixed rotary sootblower generally uses a hollow shaft to drive the sootblowing gun to rotate, the sootblowing gun is connected to the corresponding equipment, and a high-speed airflow is blown out through the sootblowing gun, thereby performing dust removal operations on the equipment. During the long-term use of the hollow shaft, due to some reasons, such as insufficient lubrication, it may be offset during use, and some common fixed rotary sootblower cannot lubricate the hollow shaft well, and cannot monitor the displacement of the hollow shaft. When the hollow shaft is offset, the sootblowing gun will be displaced and bent during the rotation process, thereby causing the sootblowing gun to affect the connection surface of the equipment, and easily cause damage to the water blowing gun, reducing the sootblowing effect.
