Description
Technical field
The utility model relates to a kind of Fan Equipment, especially a kind of low-noise fan casing.
Background technique
In the public arena of some heavy constructions at present, the ventilation requirements of one's work of demand fulfillment building interior on the one hand, also to avoid the noise pollution because causing during fan operation on the other hand, therefore silent ventilator case equipment obtains and uses widely, find in actual use, when current silent ventilator case runs, only often by noise elimination packings such as noise elimination cotton, noise is adsorbed, thus reach the object reducing noise, but due to the mounting point reason of noise elimination cotton, therefore a large amount of noise diffusion still can be caused in air, noise pollution is caused to surrounding enviroment, therefore for this present situation, in the urgent need to a kind of novel silent ventilator box structure, with the needs that satisfied reality uses.
Model utility content
This novel object be to provide a kind of can a kind of low-noise fan casing in extensive use and underground building.
In order to achieve the above object, basis is novel provides following technological scheme:
A kind of low-noise fan casing, comprise blower fan, sound absorption plate and noise elimination casing, wherein blower fan is embedded in noise elimination casing, and coaxially distribute with noise elimination casing, air inlet and exhaust outlet distance silencer box surface distance are not less than 5 centimetres, noise elimination casing is cube structure, comprise containment wall, positioning liner and elasticity silencing plate, positioning liner is tubular housing, pod apertures is established at positioning liner two ends, and pod apertures concordant with silencer box surface and with intake grill and exhaust outlet corresponding, uniform circular sound attenuation hole on positioning liner, and sound attenuation hole distributes around positioning liner axis, blower fan is arranged in positioning liner by positioning strip, and coaxially distribute with positioning liner, containment wall is coated on outside positioning liner, strengthening positioning strip is established in containment wall and pod apertures corresponding position, and strengthening positioning strip is connected with containment wall and positioning liner respectively, elasticity silencing plate is between containment wall and positioning liner, and the sound attenuation hole on elasticity silencing plate and positioning liner is interconnected, sound absorption plate is some, and be equally distributed on pod apertures end, sound absorption plate and the mutual vertical distribution of positioning liner axis.
Further, described flow-guiding mouth is bell mouth shape structure.
Further, described positioning strip and positioning liner surface of contact place establish elastic cushion block.
Further, the intake grill of described blower fan is connected by elasticity airduct with between exhaust outlet with flow-guiding mouth end face.
Further, described pod apertures place establishes air filter, and air filter is positioned at outside sound absorption plate.
This new structure is simple, rationally distributed, easy to use, on the one hand there is good installation stationkeeping ability and structural strength, can effectively the noise produced in fan operation process and air current flow process be adsorbed and be changed on the other hand, thus the noise pollution produced when effectively reducing fan operation, improve the working environment of fan operation.
Accompanying drawing explanation
In order to be illustrated more clearly in this new embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only these some novel embodiments, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is this novel mechanism schematic diagram.
Embodiment
Below in conjunction with the drawings and the specific embodiments that this is novel, be clearly and completely described this novel technological scheme, obviously, described embodiment is only this novel a part of embodiment, instead of whole embodiments.Embodiment in novel based on this, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope that this is novel protected.
A kind of low-noise fan casing as shown in Figure 1, comprise blower fan 1, sound absorption plate 2 and noise elimination casing, wherein blower fan 1 is embedded in noise elimination casing, and coaxially distribute with noise elimination casing, blower fan 1 intake grill 101 and exhaust outlet 102 are not less than 5 centimetres apart from silencer box surface distance, noise elimination casing is cube structure, comprise containment wall 3, positioning liner 4 and elasticity silencing plate 5, positioning liner 4 is tubular housing, pod apertures 6 is established at positioning liner 4 two ends, and pod apertures 6 concordant with silencer box surface and with intake grill 101 and exhaust outlet 102 corresponding, uniform circular sound attenuation hole 7 on positioning liner 4, and sound attenuation hole 7 distributes around positioning liner 4 axis, blower fan 1 is arranged in positioning liner 4 by positioning strip 8, and coaxially distribute with positioning liner 4, containment wall 3 is coated on outside positioning liner 4, containment wall 3 and pod apertures 6 corresponding position are established and are strengthened positioning strip 9, and strengthening positioning strip 9 is connected with containment wall 3 and positioning liner 4 respectively, elasticity silencing plate 5 is between containment wall 3 and positioning liner 4, and elasticity silencing plate 5 is interconnected with the sound attenuation hole 7 on positioning liner 4, sound absorption plate 2 is some, and be equally distributed on pod apertures 6 end, sound absorption plate 2 and the mutual vertical distribution of positioning liner 4 axis.
