Abstract

The invention relates to a dust-blowing device, in particular to a sound-wave dust-blowing device, and aims to solve the problem of instable wind shear, which is caused by the fact that when a rotating disc of the existing sound-wave dust blower rotates, due to change of airflow pressure, a bearing of a rotating shaft bears a relatively high load, is easily abraded and generates rotary swing of the rotating disc. The sound-wave dust-blowing device comprises a driving mechanism, a transmission shaft, a rotating bearing, a thrust bearing, a rotating disc, a housing and a blowing mechanism, wherein the driving mechanism is mounted at the upper part inside the housing; one end of the transmission shaft is connected with the driving mechanism; the rotating disc, the rotating bearing and the thrust bearing sequentially sleeve the transmission shaft from one end to the other end of the transmission shaft; a plurality of air holes are uniformly formed in the rotating disc; the blowing mechanism is mounted inside the housing; the air holes in the rotating disc are tangent to an airflow generated by the blowing mechanism. The sound-wave dust-blowing device is used for cleaning dust, rust, oxide skin and the like on a furnace wall.

Description

【Technical field】 [0001] The present invention relates to a soot blowing device, more particularly, to an acoustic wave soot blowing device. 【Background technique】 [0002] The sonic soot blower is based on the electric energy to drive the motor to rotate to generate mechanical energy to rotate the transmission turntable. The wind holes on the turntable and the air flow passing through form a wind shear, and then the wind shear generates sound waves, which cause dust, rust, and oxidation through the transmission of sound wave energy. The air in the gap area physically adhered between the skin and the pipe wall resonates, and the sound wave pressure acts on the ash layer, rust, and oxide skin to generate air pressure thrust, and then automatically separates from the pipe wall to achieve the removal and cleaning effect. The sonic soot blower is mainly used to remove dust, rust, scale, etc. on the furnace wall. When the turntable of the existing sonic soot blower rotates, the b...
