Abstract
An air return port system with acoustic absorption wedges of a silencer comprises an air return pipe and the acoustic absorption wedges, and further comprises an air pipe, wherein part of the acoustic absorption wedges are symmetrically arranged on the inner pipe wall of the air return pipe in a staggered manner, and are isosceles acute triangles; the vertex angles of the isosceles acute triangles are wedge points; the acute angle edges of the isosceles acute triangles are arranged on the windward sides of the air return pipe; the acoustic absorption wedges are made of mipor thin stainless steel plates and/or mipor thin aluminium alloy plates; the air pipe is butted and communicated with the air return pipe in the air return port of the air return pipe; the other acoustic absorption wedges are symmetrically arranged on the inner pipe wall, near the air return port, of the air pipe. Through the adoption of the air return port system, the problems of small interlayer air return pipe diameter, too high wind degree and large noise in the prior art can be solved effectively.
Description
Technical field
The present invention relates to the technical field of construction of cleaning project, relate in particular to a kind of silencing means return air inlet system with the sound-absorbing wedge for clean operating room.
Background technology
In the construction of clean operating room, the index of noise treatment is more difficult.And the generation of noise mainly causes by wind speed is too fast.Clean operating room is when design and construction, all to leave the technology interlayer of certain size, and that Construction Party and design side wish to try one's best in area that the technology interlayer takies and space is smaller, backwind tube caliber when this has just caused construction may diminish, and the backwind tube caliber diminishes and just means that wind speed will accelerate, and noise can strengthen.
Summary of the invention
The object of the invention is to design a kind of novel silencing means return air inlet system with the sound-absorbing wedge, address the above problem.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of silencing means return air inlet system with the sound-absorbing wedge comprises backwind tube and sound-absorbing wedge, is arranged with the sound-absorbing wedge on the inner tubal wall of described backwind tube, and the splitter of the described sound-absorbing wedge that is oppositely arranged shifts to install.
Described sound-absorbing wedge is isosceles acute triangle, and its drift angle forms described splitter, and its sharp edge is positioned on the windward side of described backwind tube.
Described sound-absorbing wedge is made by the corrosion resistant plate of thin plate micropore and/or the aluminium alloy plate of thin plate micropore.
Also comprise airduct, described airduct and described backwind tube are docked and connected at the return air inlet place of described backwind tube, and described airduct also is arranged with the sound-absorbing wedge near on the inner tubal wall of described return air inlet.
Described backwind tube is L-type bending backwind tube, and described backwind tube comprises front straight tube, rear straight tube and bend pipe, and described front straight tube is docked and connected by described bend pipe and described rear straight tube, and described sound-absorbing wedge is arranged on the inner tubal wall of described front straight tube and described rear straight tube.
The present invention is in return air inlet and connect the part (position of constructability before install in the air port) of return air inlet place airduct, and some groups of erasure effects sound-absorbing wedge preferably is installed relatively.The sound-absorbing wedge adopts trigone to make.The sound-absorbing wedge adopts the corrosion resistant plate of thin plate micropore and aluminium alloy plate to make.Can adopt during installation up and down dress or left and right the dress formula, last group when installing and rear one group of dislocation, leg-of-mutton sharp edge is positioned at the windward side.
Beneficial effect of the present invention can be summarized as follows:
1, the present invention is by providing a kind of silencing means return air inlet with the sound-absorbing wedging type, can solve effectively that little technology interlayer return air caliber is little, demeanour is too high with the large problem of noise.
2, the present invention is simple in structure, and is cheap for manufacturing cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
In order to make technical problem solved by the invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
A kind of silencing means return air inlet system with the sound-absorbing wedge as shown in Figure 1, comprise that backwind tube 1, airduct are (due to the content that is prior art, therefore not shown) and sound-absorbing wedge 2, be arranged with sound-absorbing wedge 2 on the inner tubal wall of described backwind tube 1, described sound-absorbing wedge 2 is isosceles acute triangle, its drift angle forms splitter, and its sharp edge is positioned on the windward side of described backwind tube 1; Described sound-absorbing wedge 2 is made by the corrosion resistant plate of thin plate micropore and/or the aluminium alloy plate of thin plate micropore, and the splitter of the described sound-absorbing wedge 2 that is oppositely arranged shifts to install.Described airduct and described backwind tube 1 are docked and connected at return air inlet 6 places of described backwind tube 1, and described airduct also is arranged with sound-absorbing wedge 2 near on the inner tubal wall of described return air inlet 6; Described backwind tube 1 is L-type bending backwind tube 1, described backwind tube 1 comprises front straight tube 3, rear straight tube 5 and bend pipe 4, described front straight tube 3 is docked and connected with described rear straight tube 5 by described bend pipe 4, and described sound-absorbing wedge 2 is arranged on the inner tubal wall of described front straight tube 3 and described rear straight tube 5.
When the high velocity air of exhausting formation passes through from backwind tube 1, high velocity air flows through between the described sound-absorbing wedge 2 that misplaces and be oppositely arranged, due to the be made sound absorption of the micropore on described sound-absorbing wedge 2 of the aluminium alloy plate by the corrosion resistant plate of thin plate micropore and/or thin plate micropore, make the noise of formation be weakened or disappear by a large amount of recovery of micropore.
More than by the detailed description of concrete and preferred embodiment the present invention; but those skilled in the art should be understood that; the present invention is not limited to the above embodiment; within the spirit and principles in the present invention all; any modification of doing, be equal to replacement etc., within protection scope of the present invention all should be included in.
