Specific embodiment
A kind of high-energy environment-friendly type acoustic wave ash ejector as shown in Figs. 1-5, including soot blower main body, air inlet pipe 1 and one end are spacious
The mouth closed cylindrical installation set 2 of the other end.The soot blower main body includes heat resisting steel loudspeaker 3 and is arranged in heat resisting steel loudspeaker
The sounding component of conventional commercial can be used in sounding component in 3, the sounding component, this is the prior art.
Certainly, in order to improve acoustic wave energy of the invention, better way is also possible that the sounding component includes one end
The air bell 8 of other end opening is connected to air inlet pipe 1, the air bell 8 is internally provided with distribution plate 9.The distribution plate 9
It is provided with screw thread on outer peripheral surface and is threadedly coupled with air bell 8, not only can guarantee the convenience of installation, but also can guarantee the steady of installation
It is qualitative.Distribution plate 9 is provided with gas collection recess portion 10 towards air inlet pipe 1 on one side, and air inlet pipe 1 can be discharged into air-flow by gas collection recess portion 10
The pressure-air of cover 8 carries out certain convergence, and the pressure of general high voltage air is maintained at 4-8KG or so.
Sounding component of the invention further includes the center-pole 11 axially extending along heat resisting steel loudspeaker 3, the center-pole 11
It is threadedly coupled in the threaded hole that inner end is protruded on distribution plate 9 and with the composition of distribution plate 9, center-pole 11 is set on the circumferential surface of inner end
It is equipped with the conical shaped projections 12 become larger along the direction far from distribution plate 9, structure between the outer rim and air bell 8 of the convex block 12
8 Inner Constitution gas mixing chamber 14 of air bell at air-flow seam 13, between the convex block 12 and distribution plate 9.The distribution plate 9
On be evenly arranged with it is several connection gas collection recess portions 10 and gas mixing chamber 14 airflow holes.It is also covered outside the outer end of the center-pole 11
Equipped with resonance cap 15, the resonance open at one end of the cap 15 towards air bell 8, other end closing.
In the process of work, pressure-air enters in air bell 8 sounding component of the present invention through air inlet pipe 1, warp
Airflow hole, which enters in the gas mixing chamber 14 of annular, to be uniformly mixed, by very fast after 13 pressurization of air-flow seam of annular after mixing well
Ejection, and form the turbulent flow of certain frequency, the air column inside the turbulent flow and resonance cap 15, which is formed, to resonate, and generation high frequency is loud
Strong sound wave, the sound wave collect amplification by heat resisting steel loudspeaker, to external diffusion from resonance 15 outer end of cap.Finally dust stratification is made to shake
It moves, fatigue, fall off.Sounding component of the present invention is not only simple in structure, energy easy for installation and can be improved acoustic wave entrainment
Power improves the effect of deashing.
The connection type of heat resisting steel loudspeaker 3 of the present invention and installation set 2 is as follows, the lesser one end of the heat resisting steel loudspeaker 3 by
The open end of installation set 2 is inserted into, and the middle part of heat resisting steel loudspeaker 3 is resisted against the edge of 2 open end of installation set and consolidates with installation set 2
Fixed connection, the mode being fixedly connected can be bonding, clamping etc., but since fire box temperature is higher, be fixedly connected to improve
Stability, better way can also be that the middle part of the heat resisting steel loudspeaker 3 and installation set 2 are welded.
In addition, itself can generate certain vibration, shake since heat resisting steel loudspeaker 3 are during sounding component sounding
When dynamic more strong, if the rigidity between heat resisting steel loudspeaker 3 and installation set 2 is too strong, it is easy that installation set 2 is driven to generate vibration together
It is dynamic, and then lead to the bolt looseness of mounting flange 4.Therefore, better way is middle part and the installation set of the heat resisting steel loudspeaker 3
Be folded between 2 buffering steel washer 6, it is described buffering steel washer 6 section be in C font, and buffer steel washer 6 respectively with it is heat-resisting
Steel loudspeaker 3 and installation set 2 are welded.The thickness for buffering steel washer 6 should not be too thick, should have certain elastic force, and buffer steel pad
Circle 6C font on one side on a certain number of notches can also be set, to improve flexibility.Buffering steel washer 6 of the invention makes
Connection between heat resisting steel loudspeaker 3 and installation set 2 has certain flexibility, so that vibration be avoided to shift to installation set 2, improves
Service life of the invention.
Circumferentially arranged on the outer surface at 2 middle part of installation set of the present invention to have a circle mounting flange 4, installation set 2 is closed
The central through hole matched with air inlet pipe 1 is additionally provided on the end face at end, one end of the air inlet pipe 1 is connected to sounding component,
The other end is pierced by outside installation set 2 through central through hole.
During the installation process, the first aperture on hearth wall, aperture size matches the present invention with installation set 2.It then will peace
Encapsulation 2 is embedded on hearth wall, the open end of installation set 2 is paid attention to during insertion in hearth wall, closed end is outside hearth wall.
Mounting flange 4 is passed through followed by bolt to squeeze into hearth wall, and installation set 2 is fixed with hearth wall.Followed by will blow
The installation of grey device main body is mounted in burner hearth and carries out, and wears the small end alignment installation set 2 of heat resisting steel loudspeaker 3 during installation
Enter, be pierced by air inlet pipe 1 through central through hole, after the middle part of heat resisting steel loudspeaker 3 pushes against the open end of installation set 2, by heat resisting steel
Processing is fixed in loudspeaker 3 and installation set 2, air inlet pipe 1 and central through hole hole wall.The hole wall of the air inlet pipe 1 and central through hole
Connection area it is relatively small, fixing process can directly adopt the mode of welding.
The present invention in the process of work, compressed air through air inlet pipe 1 enter sounding component, by sounding component sounding,
The amplified sound wave of heat resisting steel loudspeaker 3 can clear up the dust stratification on inboard wall of burner hearth.Due to sounding component base of the invention
Originally it is hidden in inside burner hearth, the noise outside burner hearth is minimum, on the one hand can maximumlly utilize acoustic wave energy, prevent energy from damaging
It loses, on the other hand also greatly improves the working environment of staff, the feature of environmental protection is fabulous.In order to further increase the effect of sound insulation
Fruit realizes the purpose of noise reduction, and sound insulation mud 5 is filled between heat resisting steel loudspeaker 3 of the present invention and installation set 2.Sound insulation mud 5 removes
To outside the effect of sound insulation, the vibration of refractory steel loudspeaker 3 can also be buffered, to improve service life of the invention.In addition to this,
Reinforcing rib 7 triangular in shape is additionally provided between the mounting flange 4 and the outer surface of installation set 2, reinforcing rib 7 can improve
The stress state of mounting flange 4 and 2 connecting portion of installation set.
