The operating at a high speed of the job demand of blower fan, the flow at high speed that could drive gas carries out relevant work, and during intake and exhaust, the wind of high speed winds miscarriage life is made an uproar the biggest, needs to carry out corresponding noise reduction process, reduces noise pollution, although common deafener can reduce the propagation of noise to a certain extent, but volume is big, and noise reduction is limited, need to improve.
Utility model content
This utility model, mainly solving the technical problems that provide a kind of MULTILAYER COMPOSITE deafener, promotes noise reduction, reduces volume.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of MULTILAYER COMPOSITE deafener, including: the first circular hole straight tube and the second circular hole straight tube, described second circular hole straight tube is arranged concentrically on the inside of the first circular hole straight tube, the two ends of described first circular hole straight tube and the second circular hole straight tube are respectively arranged with annular connecting plate and are fixed, it has been arranged concentrically the 3rd circular hole straight tube in described second circular hole straight tube, the two ends of described 3rd circular hole straight tube are respectively arranged with curved cover plate, it is respectively arranged with pod apertures in described second circular hole straight tube and the 3rd circular hole straight tube, it is provided with the first acoustical cotton in described 3rd circular hole straight tube.
In one preferred embodiment of this utility model, between described first circular hole straight tube and the second circular hole straight tube, it is provided with the second acoustical cotton.
In one preferred embodiment of this utility model, being provided with support bar and be welded and fixed between outside and the endoporus of annular connecting plate of described curved cover plate, described support bar is cylindrical bar.
In one preferred embodiment of this utility model, described first circular hole straight tube is galvanized sheet straight tube, uses and be weldingly connected between end and the cylindrical of annular connecting plate of described first circular hole straight tube.
In one preferred embodiment of this utility model, use between end and the curved cover plate of described 3rd circular hole straight tube and be weldingly connected.
The beneficial effects of the utility model are: a kind of MULTILAYER COMPOSITE deafener that this utility model is pointed out, using concentric composite construction, volume is compacter, utilizes the 3rd circular hole straight tube and the first acoustical cotton to promote the effect of noise reduction, it is arranged on blower fan, the noise pollution of blower fan can be greatly reduced.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of this utility model a kind of MULTILAYER COMPOSITE deafener one preferred embodiment.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, this utility model embodiment includes:
A kind of MULTILAYER COMPOSITE deafener, including: the first circular hole straight tube 1 and the second circular hole straight tube 2, described second circular hole straight tube 2 is arranged concentrically on the inside of the first circular hole straight tube 1, it is provided with the second acoustical cotton 3 between described first circular hole straight tube 1 and the second circular hole straight tube 2, described first circular hole straight tube 1 is galvanized sheet straight tube, utilizes the second acoustical cotton 3 to reduce the outside propagation of noise.
The two ends of described first circular hole straight tube 1 and the second circular hole straight tube 2 are respectively arranged with annular connecting plate 4 and are fixed, use between end and the cylindrical of annular connecting plate 4 of described first circular hole straight tube 1 and be weldingly connected, good sealing effect, is prevented effectively from the energy consumption and noise leaked gas and increase.
It has been arranged concentrically the 3rd circular hole straight tube 8 in described second circular hole straight tube 2, the two ends of described 3rd circular hole straight tube 8 are respectively arranged with curved cover plate 6, it is respectively arranged with pod apertures in described second circular hole straight tube 2 and the 3rd circular hole straight tube 8, it is provided with the first acoustical cotton 7 in described 3rd circular hole straight tube 8, utilize the first acoustical cotton 7 to increase sound-absorbing effect, effectively reduce noise.
Being provided with support bar 5 between outside and the endoporus of annular connecting plate 4 of described curved cover plate 6 to be welded and fixed, described support bar 5 is cylindrical bar, and windage is little, it is to avoid the impact on air-flow, reduces the wind-dryness that support bar 5 causes.
