Abstract
The utility model discloses an improved generation amortization ventilation connecting pipe, including acceping pipeline, connecting tube and air pipe, the both ends of acceping the pipeline are fixed with annular end plate, and the air pipe plug bush is in acceping the pipeline, and air pipe's both ends are fixed on two rings shape end plate, and the plug bush has the wave body among the air pipe, and the wave body is at air pipe and accept between the pipeline, the both ends centre gripping of wave body between two rings shape end plate, air pipe and accept that the packing has porous shape granule between the pipeline, wave body and air pipe are the perforated plate and make. Its absorbing effect is good, the greatly reduced noise, simultaneously, its intensity of strengthening acceping the pipeline under the condition that does not influence the ventilation to guarantee the bulk strength.
Description
Technical field:
This utility model relates to blower fan technical field, more specifically to a kind of modified model noise reduction
Air handling connection.
Background technology:
Existing silencing ventilation pipline is usually and is inserted with the connection that porous plate is made in body
Pipeline, is provided with glass cotton or other deadener at silencing ventilation pipline with being connected between pipeline
Carry out noise reduction, but its noise reduction is limited, and the length of silencing ventilation pipline is longer, its
Inner supporting structure is few, it is impossible to increase the intensity of body.
Utility model content:
The purpose of this utility model is aiming at the deficiency of prior art, and provides a kind of modified model
Noise reduction air handling connection, its sound-absorbing effect is good, is substantially reduced noise, and meanwhile, it is at not shadow
Ring the intensity strengthening accommodating conduits in the case of ventilating, thus ensure bulk strength.
Technology solution of the present utility model is as follows:
A kind of modified model noise reduction air handling connection, including accommodating conduits, connects pipeline and ventilation duct
Road, the two ends of described accommodating conduits are fixed with annular endplate, and ventilation shaft sleeve is at accommodating conduits
In, the two ends of ventilation shaft are fixed on two annular endplates, are inserted with wave in ventilation shaft
Shape body, waveform body between ventilation shaft and accommodating conduits, the two ends of waveform body
It is clamped between two annular endplates, between ventilation shaft and accommodating conduits, is filled with porous
Grain；
Described waveform body and ventilation shaft are porous plate and make.
Described accommodating conduits is bolted to connection is formed by multiple body of being in charge of.
Described ventilation shaft is inserted with the middle spacer sleeve that porous plate is made, the two ends of ventilation shaft
Being inserted with end plate, end plate has multiple opening, the two ends of middle spacer sleeve are pressed against two ends
On plate, stationary annular limiting plate on annular endplate, end plate is clamped in annular stop plate and middle interval
Between set.
The two ends of described waveform body are bolted to connection on annular endplate.
The two ends of described ventilation shaft are bolted to connection on two annular endplates.
The bottom of described accommodating conduits is fixed with leg.
Described porous granule is that ceramic porous material is made.
The beneficial effects of the utility model are:
Its sound-absorbing effect is good, is substantially reduced noise, and meanwhile, it is not affecting the situation of ventilation
The intensity of lower reinforcement accommodating conduits, thus ensure bulk strength.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing of Fig. 1.
Detailed description of the invention:
Embodiment: as shown in Fig. 1 to Fig. 2, a kind of modified model noise reduction air handling connection, including
Accommodating conduits 10, connection pipeline 20 and ventilation shaft 30, the two ends of described accommodating conduits 10
Be fixed with annular endplate 11, ventilation shaft 30 sleeve in accommodating conduits 10, ventilation shaft
The two ends of 30 are fixed on two annular endplates 11, are inserted with waveform in ventilation shaft 30
Body 40, waveform body 40 between ventilation shaft 30 and accommodating conduits 10, waveform
The two ends of body 40 are clamped between two annular endplates 11, and ventilation shaft 30 is managed with housing
Porous granule 50 it is filled with between road 10；
Described waveform body 40 and ventilation shaft 30 are porous plate and make.
Further, described accommodating conduits 10 is in charge of body 12 company of being bolted by multiple
Connect and form.
Further, described ventilation shaft 30 is inserted with the middle spacer sleeve that porous plate is made
31, the two ends of ventilation shaft 30 are inserted with end plate 32, and end plate 32 has multiple opening
33, the two ends of middle spacer sleeve 31 are pressed against on two end plates 32, fixing on annular endplate 11
Annular stop plate 34, end plate 32 is clamped between annular stop plate 34 and middle spacer sleeve 31.
Further, the two ends of described waveform body 40 are bolted to connection at ring
On shape end plate 11.
Further, the two ends of described ventilation shaft 30 are bolted to connection at two
On annular endplate 11.
Further, the bottom of described accommodating conduits 10 is fixed with leg 13.
Further, described porous granule 50 is made for ceramic porous material.
In the present embodiment, accommodating conduits 10 and ventilation duct can be strengthened by waveform body 40
Intensity between road 30, meanwhile, waveform body 40 can upset wind direction, thus preferably
The noise of air quantity when reducing flowing, thus play Noise Reduction.
And porous granule 50 is made for ceramic porous material, end plate 32 has multiple circulation
Hole 33, waveform body 40 and ventilation shaft 30 are porous plate and make, thus further
Noise reduction.So that noise reduction is more preferable.
