And shaft coupling, realization are directly driven by high-speed motor, the single-stage high-speed centrifugal air blower adjusted the speed by frequency converter.
Since magnetic suspension air blower revolving speed is higher compared to conventional fan revolving speed, when start and stop built-in blow valve exhaust noise compared with
Greatly, very big influence is caused to running environment.
Summary of the invention
In view of this, the present invention is directed to propose a kind of silencing means of magnetic suspension air blower emptying, disappears with the use of air inlet
The quadruple sound deadening of sound tube, sound attenuator, silencing baffles and outlet air hush pipe is effectively reduced magnetic suspension air blower start and stop and puts
Noise when empty.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of silencing means of magnetic suspension air blower emptying, including sound attenuator；It is staggered in sound attenuator equipped with multiple
Silencing baffles, multiple silencing baffles constitute the airflow channel of S type, and the outer layer of silencing baffles is porous plate, is filled out inside silencing baffles
Fill acoustical cotton；The top and bottom end of sound attenuator be respectively welded outlet air hush pipe and air inlet hush pipe, sound attenuator, outlet air hush pipe and
The internal layer for entering the wind hush pipe is porous plate, and outer layer is imperforate plate, and acoustical cotton is filled between porous plate and imperforate plate；Air inlet disappears
Sound tube lower end is connect by blow valve with magnetic suspension air blower, and outlet air hush pipe upper end is in communication with the outside.
Further, the quantity of silencing baffles is four.
Further, multiple silencing baffles are welded to connect with sound attenuator.
Further, equidistant between multiple silencing baffles.
Further, each silencing baffles are vertically set in sound attenuator.
Compared with the existing technology, a kind of silencing means of magnetic suspension air blower emptying of the present invention has following excellent
Gesture:
A kind of silencing means of magnetic suspension air blower emptying of the present invention, with the use of air inlet hush pipe, sound attenuator,
The quadruple sound deadening of silencing baffles and outlet air hush pipe is effectively reduced the noise when emptying of magnetic suspension air blower start and stop,
The present apparatus not only reduces running noises and improves the operating condition of magnetic suspension air blower operation.
