Abstract
The utility model relates to a spiral sound wave magnifying device which comprises sound wave guide tubes. The sound wave guide tubes comprise a spiral sound wave guide tube, a medium sound wave guide tube and a large sound wave guide tube, wherein the spiral sound wave guide tube, the medium sound wave guide tube and the large sound wave guide tube are all reducing elbows. The large opening end of the spiral sound wave guide tube is connected with the small opening end of the medium sound wave guide tube, and the large opening end of the medium sound wave guide tube is connected with the small opening end of the large sound wave guide tube. The spiral sound wave magnifying device has the advantages that the sound wave magnifying device is of a spiral structure, and thus occupied space is small through the structure when the spiral sound wave magnifying device is mounted.
Description
Technical field
The utility model relates to a kind of sound wave amplifier, relates in particular to a kind of spirality sound wave amplifier.
Background technology
The efficient soot blower of sound wave has in the application of the dust stratification of removing boiler heat exchange face, its critical piece sound wave amplifier is straight structure, because sound wave expands the needs of putting, the sound wave amplifier of this structure, the long enough that its length need to design, while installation at the scene, take up room large, after installation, take boiler maintenance passage.
Utility model content
A kind ofly take up an area little sound wave and amplify and repair effective spirality sound wave amplifier but technical problem to be solved in the utility model is to provide.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of spirality sound wave amplifier, described acoustic waveguide tube comprises spirality acoustic waveguide tube, middle acoustic waveguide tube, large acoustic waveguide tube, wherein, described spirality acoustic waveguide tube, middle acoustic waveguide tube, large acoustic waveguide tube is the conduit that is round table-like;
The big opening end of described spirality acoustic waveguide tube is connected with the osculum end of described middle acoustic waveguide tube, and the big opening end of described middle acoustic waveguide tube is connected with the osculum end of described large acoustic waveguide tube.
The beneficial effects of the utility model are: sound wave amplifier is sped structure, this kind of structure can take up room little when mounted, length to effective growth sound wave amplifier under the less prerequisite of boiler maintenance passage area occupied after installation, in the situation that not increasing air line distance, increase Acoustic Wave Propagation distance, increase the multiplication factor of sound wave, simultaneously, sped structure can effectively reduce the frequency of the radio-frequency component in sound wave, high frequency sound wave is converted to low-frequency sound wave, low-frequency sound wave has better diffraction, contribute to sound wave to propagate farther distance at the more boiler internal of barrier.
On the basis of technique scheme, the utility model can also do following improvement.
Further, its inwall curve of described spirality acoustic waveguide tube is exponential curve, and inwall curved surface is smooth.
Further, described spirality sound wave amplifier inwall connection is and is smoothly connected.
Further, between described spirality acoustic waveguide tube and described middle acoustic waveguide tube, be provided with connecting bolt,
Described spirality acoustic waveguide tube is connected by connecting bolt with described middle acoustic waveguide tube.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In accompanying drawing, the list of parts of each label representative is as follows:
1, spirality acoustic waveguide tube, 2, middle acoustic waveguide tube, 3, large acoustic waveguide tube, 4, connecting bolt.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, the big opening end of spirality acoustic waveguide tube (1) is connected with the osculum end of middle acoustic waveguide tube (2), the big opening end of middle acoustic waveguide tube (2) is connected with the osculum end of large acoustic waveguide tube (3), spirality acoustic waveguide tube (1) is fastening with bolt (4) with middle acoustic waveguide tube (2), and middle acoustic waveguide tube (2) is welded together with large acoustic waveguide tube (3).When work, sound wave enters from sound wave amplifier osculum end, through spirality acoustic waveguide tube (1), middle acoustic waveguide tube (2), large acoustic waveguide tube (4), emits from sound wave amplifier big opening end, and big opening end diameter is large compared with osculum end diameter, and sound wave sound pressure level increases.Ripple amplifier is sped structure, this kind of structure can take up room little when mounted, length to effective growth sound wave amplifier under the less prerequisite of boiler maintenance passage area occupied after installation, in the situation that not increasing air line distance, increase Acoustic Wave Propagation distance, increase the multiplication factor of sound wave, simultaneously, sped structure can effectively reduce the frequency of the radio-frequency component in sound wave, high frequency sound wave is converted to low-frequency sound wave, low-frequency sound wave has better diffraction, contributes to sound wave to propagate farther distance at the more boiler internal of barrier.Sound wave amplifier inwall curve is exponential curve, and inwall curved surface is smoothly connected.Guarantee the effective amplification to sound wave.Spirality sound wave amplifier increases Acoustic Wave Propagation distance in the situation that not increasing air line distance, increase the multiplication factor of sound wave, simultaneously, sped structure can effectively reduce the frequency of the radio-frequency component in sound wave, high frequency sound wave is converted to low-frequency sound wave, low-frequency sound wave has better diffraction, contributes to sound wave to propagate farther distance at the more boiler internal of barrier.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
