Sonic Soot Blower With Floating Diaphragm

Abstract: The present invention relates to a sonic soot blower, comprising a sound wave generator and a sound wave transmission path, wherein the sound wave generator comprises a U-shaped diaphragm housing, an annular diaphragm seat, a diaphragm and a cover, the sound wave transmission path comprises a sound output stub and a horn mouth threaded jointed with each other, wherein the U-shaped diaphragm housing has a bottom and two vertical straight side walls, on the wall there is a gas inlet hole, and at the bottom there is a central through hole connecting to the sound wave transmission path; the annular diaphragm seat is concentrically tightened onto the internal bottom of the diaphragm housing, on the diaphragm seat the diaphragm freely sits; the cover is tightened on top surface of the diaphragm housing by tightening members and has a raised annular spigot pressing on the diaphragm rim, with a diameter matching the inside diameter of the diaphragm housing; when compressed gas is fed into the diaphragm housing via the gas inlet hole from a solenoid valve, the diaphragm freely floats on the diaphragm seat and repeatedly buckles and resumes to produce sound waves which exit from the sound wave transmission path. The sonic soot blower with a floating diaphragm is not easily prone to pre-mature failures, its structure is simple with low noise level, all components are easy to be removed for repair or replacement, and it has high applicability.
