Abstract

The invention relates to the technical field of acoustic wave ash removing, and aims to provide a high-power acoustic vibration generator which is light in structure, simple to assemble and convenient in field installation. The high-power acoustic vibration generator comprises an input disc, a sound production disc, an output disc and a motor, and is characterized in that the input disc is provided with an air flow input port, the output disc is provided with a sound output port, the input disc and the output disc are buckled and fixed, the air flow input port and the sound output port are opposite to each other in a mode of sharing the same center line, the sound production disc is arranged between the input disc and the output disc, a clearance is reserved between the sound production disc and the input disc, a clearance is reserved between the sound production disc and the output disc, the periphery of the sound production disc is provided with a plurality of air flow cutting holes which are uniformly distributed in the circumferential direction, the motor is arranged at the outer side of the input disc and fixedly connected with the input disc, a motor shaft of the motor is directly connected with the sound production disc so as to drive the sound production disk to rotate, and the air flow cutting holes share the same center line with the air flow input port and the sound output port.

Description

technical field [0001] The invention relates to the technical field of acoustic wave ash removal, in particular to a high-power acoustic vibration generator. Background technique [0002] The sonic ash remover is a device that modulates compressed air into sound waves, which can be used for boiler ash removal. When in use, it will input sound waves into the boiler to remove ash from the heat exchange area of ​​the boiler. The internal structure of the current sonic dust remover is complicated, and the turntable adopts independent shafts and bearings. Correspondingly, the input disc and output disc need to be processed with independent bearing housings to fix the bearings. The processing and assembly are time-consuming and laborious, and are prone to processing or assembly deviations. This structure needs to use a coupling to connect the motor shaft and the shaft end of the sonic dust remover, which increases the complexity of the equipment and has high requirements for the c...

AI Technical Summary

Problems solved by technology

The internal structure of the acoustic wave dust remover is complicated, and the turntable adopts independent shafts and bearings. Correspondingly, the input disk and the output disk need to be processed with independent bearing seats to fix the bearings. The processing and assembly are time-consuming and laborious, and are prone to processing or assembly deviations.

This structure needs to use a coupling to connect the motor shaft and the shaft end of the sonic dust remover, which increases the complexity of the equipment and has high requirements for the concentricity of the motor shaft and the turntable shaft. For small factories with relatively imperfect fixtures, Its installation yield is low, and the equipment repair rate is high

This high-standard assembly process results in the gap between the turntable and the input and output disks not being less than 1 mm, otherwise it will seriously affect the yield of the equipment

At the same time, the equipment is complex and the weight of the equipment is increased. When installing on site, a support frame is required to support the bottom. In order to eliminate the influence caused by thermal expansion and contraction of the boiler, the structure of the support frame is complex and the cost is high.
