Abstract
The invention discloses a high-flow ventilator silencer and a manufacturing method thereof. A silencer shell of a ventilator is manufactured into a rectangular cylinder body shape, the cross-sectional shape of the silencer shell which is manufactured into a rectangular cylinder body shape is rectangular, and the side length of each side of the rectangular section is greater than the diameter of a round pipeline connected with the ventilator. The silencer shell of the ventilator is manufactured into a rectangular cylinder body shape, a reducer union with a square upper part and a round lower part is adopted, the silencer shell of the rectangular cylinder body shape is connected to the round pipeline of the ventilator, and the sealability is more superior to that of the cylindrical shell of the silencer for the traditional ventilator. By virtue of the contrast testing with the existing silencer, when the existing silencer is used for a high-flow fan, the treatment air quantity is 240000m<3>/h, and the noise reduction effect does not exceed 8 decibels, but the noise reduction effect of the silencer provided by the invention can achieve 15 decibels at same service conditions and is far superior to the noise reduction effect of the existing silencer.
Description
Technical field
The present invention relates to a kind of big flow ventilator baffler and preparation method thereof, belong to ventilator baffler technical field.
Background technique
At present; In the existing technology; Mostly the general used muffler shell of ventilator is circular core structure, though the characteristics that this structure has is in light weight, volume is little, its erasure effect is unsatisfactory; And when using it to handle suction port and be the noise reduction of big flow ventilator of the above flow of 100000 m3/h, its erasure effect is poorer.So existing ventilator baffler still can not satisfy the needs that big flow ventilator noise reduction is used.
Summary of the invention
The objective of the invention is: a kind of simple in structure, the big preferably flow ventilator of erasure effect baffler and preparation method thereof is provided, to overcome the deficiency of existing technology.
Technological scheme of the present invention is achieved in that a kind of big flow ventilator baffler making method of the present invention is that muffler shell with ventilator is made into the rectangular cylinder shape.
The above-mentioned sectional shape that is made into the muffler shell of rectangular cylinder shape is a rectangle, and the length of side on each limit of this rectangular cross-section is all greater than the diameter of the circular pipe that is connected with ventilator.
A kind of big flow ventilator baffler of making according to method of the present invention does; Comprise muffler shell; Muffler shell is the rectangular cylinder shape; Be connected with at the air outlet end of the muffler shell of rectangular cylinder shape and be used for the reducer union that is connected with the circular pipe of ventilator, an end of reducer union is that rectangular port, the other end are circular port, and reducer union is connected with the circular pipe of ventilator through circular port.
In above-mentioned muffler shell, be equipped with and erect the bloop of placing.
Above-mentioned bloop is made up of framework, mask web plate and acoustical cotton, and the mask web plate is separately fixed at the two sides of framework, and acoustical cotton is filled in the space that mask web plate and framework constituted.
On the surface of above-mentioned mask web plate, also be coated with one deck glass fibre cloth.
Front end at above-mentioned every bloop also is provided with the V-arrangement fluid director.
Suction port end at above-mentioned muffler shell is provided with steel mesh.
Steel mesh rear at the suction port end of above-mentioned muffler shell also is provided with stainless steel filtering net.
Owing to adopted technique scheme; The present invention is made into the rectangular cylinder shape with the muffler shell of ventilator; And the reducer union of circle with adopting an old name for the Arabian countries in the Middle East; Receive the muffler shell of this rectangular cylinder shape on the circular pipe of ventilator, make its sealing more be superior to the cylindrical shell of the used baffler of tradition ventilation machine; And the present invention erects to place in the muffler shell of rectangular cylinder shape and contains the cotton bloop with holes of noise reduction, can reach the performance of better sound-deadening and noise-reducing like this.Warp and existing baffler contrast test, existing baffler are used in when the processing air quantity is 240000m3/h on the big flow blower fan, and its sound-deadening and noise-reducing effect is no more than 8 decibels; And the present invention's baffler noise reduction of the present invention under identical use condition can reach 15 decibels, considerably beyond existing baffler sound-deadening and noise-reducing effect; In addition, it is inner that the present invention can prevent effectively that insect or particulate matter from getting into baffler, gets in the ventilator damage of avoiding it possibly cause ventilator thereby protection prevents insect or particulate matter.Therefore; The present invention compared with prior art; Advantage simple in structure, good muffling effect that the present invention not only has makes easily, uses advantages such as easy to maintenance, the present invention can also prevent effectively that ventilator from being taken place by the phenomenon of insect or particulate matter damage when work but also have.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Embodiments of the invention: when making the baffler of existing ventilator use, make according to a kind of big flow ventilator baffler making method of the present invention, the muffler shell that is about to ventilator is made into the rectangular cylinder shape; During making; In order to reach better erasure effect; The sectional shape of the muffler shell that is made into the rectangular cylinder shape is made into the rectangle of square or rectangular, and the length of side on each limit of this rectangular cross-section all is made into the diameter greater than the circular pipe that is connected with ventilator.
The structural representation of a kind of big flow ventilator baffler of making according to method of the present invention such as Fig. 1～shown in Figure 4; During making; Muffler shell 1 is made as the rectangular cylinder shape; End connects one and is used for the reducer union 2 that is connected with the circular pipe of ventilator in the air outlet of the muffler shell 1 of rectangular cylinder shape; One end of this reducer union 2 is made as the rectangular port that is connected with muffler shell 1, its other end is made as circular port, reducer union 2 is connected with the circular pipe of ventilator through this circular port; In order to reach better erasure effect, in muffler shell 1, install and erect the bloop of placing 3; This bloop 3 is formed (as shown in Figure 5) by framework 3.1, mask web plate 3.2 and acoustical cotton 3.3; During making; Mask web plate 3.2 is separately fixed at the two sides of framework 3.1; Acoustical cotton 3.3 is filled in the space that mask web plate 3.2 and framework 3.1 constituted, on the surface of mask web plate 3.2, covers one deck glass fibre cloth 3.4 simultaneously again; For in use, reduce resistance to air-flow, can be at the fixing V-arrangement fluid director 4 of the front end of every bloop 3; In order to prevent that insect or particulate matter from getting in the muffler shell in when work, can install steel mesh 5 at the suction port end of muffler shell 1, and a stainless steel filtering net 6 is installed at steel mesh 5 rears of the suction port end of muffler shell 1 again.
