Abstract
The utility model discloses a kind of air-flows to cut flying disc type sonic soot blowing device, including housing, rotating disk, driving motor, loudspeaker；Rotating disk is equipped with spray orifice, when rotating disc spins, periodically cuts high pressure draught.The present apparatus does not have vibrating diaphragm structure, will not generate metal fatigue phenomenon, and stable and reliable working performance can go work, long lifespan for high temperature；The dynamic medium of generator is compressed air, passes through low-frequency pulse resonance sounding, gas sound high conversion efficiency.Any damage will not be caused to heating surface, and the utility model design structure is compact using the product deashing, noise is small, and noise is less than 70db at 1 meter away from soot blower.
Description
Technical field
The utility model is related to sound wave ash cleaners, relate in particular to a kind of air-flow cutting flying disc type sonic soot blowing dress
It puts.
Background technology
In boiler running process, due to viscous between the surface traction of grey particle, particle and between particle and stove inner tubal wall
Tie various effects such as power, molecular adhesion, electrostatic attraction and chemical affinity, the heat exchange at burner hearth and each position of flue
Dust deposition will be gradually formed on face.
In denitration operational process, in order to persistently provide effective air-flow to catalyst and ensure effective operation, need
Active, effective deashing are carried out using sound wave ash cleaner.
Utility model content
Goal of the invention：The purpose of this utility model is to provide a kind of by cutting compressed air generation sound frequency realization sound
The device of wave soot blowing.
Technical solution：To achieve the above object, a kind of air-flow cutting flying disc type sonic soot blowing device of the utility model, packet
Include housing, in housing and surface open up spray orifice rotating disk, from hull outside one end connection rotating disk driving motor, with
And it is installed on the loudspeaker of the hull outside other end；It is the venting cavity for accommodating rotating disk in the housing, venting cavity is through housing table
First opening in face is connected with loudspeaker, and second opening of the venting cavity through surface of shell is connected with high-pressure air source, the rotating disk patch
Nearly housing is located at the inner wall of the first opening, and when rotating disc spins, the spray orifice is periodically overlapped with the described first opening
Or it partly overlaps.
The one side of the housing close to rotating disk includes datum level and groove surface, and the datum level is equipped with opening and with first
Open communication, the groove surface relative datum face further to lower recess, groove surface be equipped with opening and with the second open communication.
After pressure-air enters housing vent chamber from the second opening, first pass through between rotating disk front end and groove surface
Space, the spray orifice being then passed through in rotating disk enter the space between rotation back-end disk and housing, then using spray orifice, through benchmark
Face is sprayed by the first opening in horn chamber.During air enters the first opening through spray orifice, rotating disk is above datum level
Air is cut, forms the high pressure draught of certain frequency, the resonance sounding in loudspeaker.
The rotating disk is equipped with 2~6 spray orifices, and it is identical with the first opening to spray empty size.Preferably, the rotating disk spray orifice
Quantity is 4.
The loudspeaker include the enlarging section gradually to broaden with the resonance part of the first opening connection and bore.Preferably, it is described
Bending section is additionally provided between the resonance part of loudspeaker and enlarging section.
Advantageous effect：The utility model does not have vibrating diaphragm structure, will not generate metal fatigue phenomenon, stable work in work
Reliably, work, long lifespan can be gone for high temperature；The dynamic medium of generator is compressed air, by low-frequency pulse resonance sounding,
Gas sound high conversion efficiency.Any damage will not be caused to heating surface, and the utility model design structure is tight using the product deashing
It gathers, noise is small, and noise is less than 70db at 1 meter away from soot blower.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the cross-sectional view of Fig. 1 middle housing parts；
Fig. 3 is the vertical section schematic diagram of Fig. 1 middle housing parts.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of air-flow cutting flying disc type sonic soot blowing device, including housing 1, in housing 1 and
Surface opens up the rotating disk 2 of 4 spray orifices 7, connects the driving motor 3 of rotating disk 2 from 1 lateral ends of housing and be installed on shell
The loudspeaker of the 1 outside other end of body；Be the venting cavity 4 for accommodating rotating disk 2 in housing 1, venting cavity 4 through 1 surface of housing first
Opening 5 is connected with loudspeaker, second being open and 6 connected with high-pressure air source through 1 surface of housing of venting cavity 4, and rotating disk 2 is close to housing 1
It is identical with the first opening 5 to spray empty size for inner wall at the first opening 5.When rotating disk 2 rotates, spray orifice 7 periodically with
First opening 5 overlaps or partly overlaps.
The one side of housing 1 close to rotating disk 2 includes datum level 11 and groove surface 12, and datum level 11 is equipped with opening and with first
5 connection of opening, further to lower recess, groove surface 12 is equipped with opening and connects with the second opening 6 in groove surface 12 relative datum face 11
It is logical.
Loudspeaker include the enlarging section 9 gradually to broaden with resonance part 8, bending section 10 and the bore that the first opening 5 is connect.
The above is only the preferred embodiment of the utility model, it should be pointed out that：For the common skill of the art
For art personnel, under the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
