Abstract

The invention discloses a diffusion taper pipe silencer for a blower. The diffusion taper pipe silencer for the blower comprises a diffusion taper pipe body with an air inlet, an air outlet and a shell; the section of the air inlet is smaller than the section of the air outlet; the air inlet is provided with a first fixing drum; the air outlet is provided with a second fixing drum; a perforated plate is arranged in the shell; a partition plate is arranged between the perforated plate and the shell; the partition plate divides the space between the perforated plate and the shell into upper and lower parts; the silencer is arranged in the upper and lower parts. The diffusion taper pipe for the blower is simple and novel in structure and convenient to mount, and the diffusion taper pipe and the silencer are integrated, so diffusion is realized, the gas flow speed is reduced, the noise caused by high-speed air flows is absorbed, the manufacturing cost and space are saved and the structure of the blower is enabled to be more compact.

Description

A kind of blower diffusion Taper Pipe baffler
Technical field
The present invention relates to silencer of blower field, be 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.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the present invention combines diffusion Taper Pipe and baffler, provides the diffusion Taper Pipe baffler that a kind of technical ability diffusion again can noise reduction.
The object of the invention 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, disclosed a kind of blower diffusion Taper Pipe baffler, has 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, save manufacture cost simultaneously, also saved space, made blower fan structure compactness.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing of the present invention, the technological scheme of the embodiment of the present invention is carried out to clear, complete description.
As shown in Figure 1, disclosed a kind of blower diffusion Taper Pipe baffler, 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 invention 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 spirit of the present invention based on announcement of the present invention; therefore; protection domain of the present invention should be not limited to the content that embodiment discloses; and should comprise various do not deviate from replacement of the present invention and modifications, and contained by present patent application claim.
