Abstract
The utility model discloses a blower tapered diffuser silencer comprising a tapered diffuser body. The tapered diffuser body comprises an air inlet, an air outlet and a shell. The section of the air inlet is smaller than that of the air outlet. The air inlet is provided with a first fixing cylinder; the air outlet is provided with a second fixing cylinder. An orifice plate is disposed within the shell; a partition is disposed between the orifice plate and the shell. Space between the orifice plate and the shell is divided by the partition into an upper portion and a lower portion. A silencing unit is disposed in each of the upper and lower portions. The blower tapered diffuser silencer is simple and novel in structure and convenient to mount; by combining the tapered diffuser and the silencer, diffusion is achieved, air flow speed is decreased, noise caused by high-speed air flow is absorbed, manufacturing cost and space are saved, and a blower is more compact in structure.
Description
Technical field
The utility model relates to silencer of blower field, is specifically related to the blower diffusion Taper Pipe baffler of a kind of combination noise reduction and diffusion Taper Pipe.
Background technique
Baffler is a kind of in allowing air-flow to pass through, can effectively stop or weaken again the device that acoustic energy is outwards propagated, be mainly used in the noise control of import and export pipeline or the ventilation duct of machinery, in blower, there is use baffler, but in general blower, baffler and diffusion Taper Pipe are separate, therefore equipment occupation space is large, arranges inconvenient.
Model utility content
Model utility object: in order to solve the deficiencies in the prior art, the utility model combines diffusion Taper Pipe and baffler, provides the diffusion Taper Pipe baffler that a kind of technical ability diffusion again can noise reduction.
The purpose of this utility model is to realize by such technological scheme, a kind of blower diffusion Taper Pipe baffler, comprise diffusion Taper Pipe body, described diffusion Taper Pipe body has intake grill, exhaust outlet and shell, described intake grill cross section is less than described exhaust outlet cross section, described intake grill is provided with the first stationary magazine creel, described exhaust outlet is provided with the second stationary magazine creel, described enclosure is provided with orifice plate, between described orifice plate and described shell, be provided with dividing plate, the spatial separation between described orifice plate and described shell is become upper and lower by described dividing plate, in described upper and lower, be provided with silencer.
Described intake grill is provided with the first flange, and described exhaust outlet is provided with the second flange.
Described orifice plate is provided with glass cloth towards a side of described shell.
Described glass cloth is the plain weave alkali-free glass cloth of thickness 0.1mm.
Described silencer is silencing cotton or acoustical panel.
Described diffusion Taper Pipe cross section is trapezoidal.
Spacing between described orifice plate and described shell is 25～30mm.
Compared with prior art, a kind of blower diffusion Taper Pipe baffler that the utility model discloses, there is novelty simple in structure, easy for installation, diffusion Taper Pipe and baffler are united two into one, not only realize diffusion but also realize noise reduction, saved manufacture cost simultaneously, also save space, made blower fan structure compactness.
Brief description of the drawings
Fig. 1 is structure sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, the utility model embodiment's technological scheme is carried out to clear, complete description.
As shown in Figure 1, a kind of blower diffusion Taper Pipe baffler that the utility model discloses, diffusion Taper Pipe and baffler are united two into one, specifically comprise diffusion Taper Pipe body 1, described diffusion Taper Pipe body 1 has intake grill 12, exhaust outlet 11 and shell 13, described diffusion Taper Pipe body 1 cross section is trapezoidal, described intake grill 12 cross sections are less than described exhaust outlet 11 cross sections, described intake grill 12 is provided with the first stationary magazine creel 3, described exhaust outlet 11 is provided with the second stationary magazine creel 2, described shell 13 inside are provided with orifice plate 4, and between described orifice plate 4 and described shell 13, spacing is 25～30mm, described orifice plate 4 is provided with 0.1mm plain weave alkali-free glass cloth 5 towards a side of described shell 13, between described orifice plate 4 and described shell 13, be provided with dividing plate 6, the spatial separation between described orifice plate 4 and described shell 13 is become upper and lower by described dividing plate 6, in described upper and lower, be filled with silencer 7, described silencer 7 is silencing cotton or acoustical panel, the first flange 9 is installed on described intake grill 12, be fixedly connected with blower by described the first flange 9, the second flange 8 is installed on described exhaust outlet 11, be fixedly connected with exhaust duct by described the second flange 8.
Technology contents of the present utility model and technical characteristics have disclosed as above; but those of ordinary skill in the art still may do all replacement and modifications that does not deviate from the utility model spirit based on announcement of the present utility model; therefore; the utility model protection domain should be not limited to the content that embodiment discloses; and should comprise various do not deviate from replacement of the present utility model and modifications, and contained by present patent application claim.
