Abstract
The utility model discloses a silencing device. The silencing device comprises an air inlet, a silencing tube and an air outlet. The silencing tube comprises a shell body and a separation plate; the separation plate divides the silencing tube into an upper tube body and a lower tube body which are communicated with each other; the air inlet is communicated with the upper tube body; the air outlet is communicated with the lower tube body; an inner wall surface of the shell body is provided with a glass wool layer; and the upper tube body and the lower tube body are respectively provided with silencing hole plates. According to the silencing device, air flowing pipelines and the corresponding silencing hole plates are adopted, and at the same time, the inner wall surface of the silencing tube is provided with the glass wool layer, and a shockproof sound-insulation layer is arranged at the external of the silencing tube; and therefore, the silencing device is advantageous in ingeniously designed structure, compact structure, easiness in processing and maintenance, favorable silencing effect, economical and practical properties, avoidance of produced secondary noise, and great value in marketing.
Description
Technical field
The utility model relates to the quieter art, refers in particular to a kind of have compact conformation, quieter that soundproof effect is good.
Background technology
Along with the progress of science and technology, suitability for industrialized production is more and more flourishing, and still, environmental pollution is also thereupon more and more serious, and noise pollution is exactly one of them.A lot of plant equipment can be sent very large noise in the process of running, engine or the generators and other machines equipment take gasoline or diesel oil as power for example, and the toxic emission meeting produces very large noise.How to reduce this type of noise and become a great problem in the modern production.In the existing quieter, not only erasure effect is undesirable, and easily produces the secondary noise pollution.Other erasure effect preferably quieter is then bulky, and daily servicing complexity and cost are higher.
Summary of the invention
In view of this, the utility model is for the disappearance of prior art existence, and its fundamental purpose provides the quieter of a kind of compact conformation, good muffling effect.
For achieving the above object, the utility model adopts following technical scheme: a kind of quieter, include an air intake opening, hush pipe and exhausr port, described hush pipe includes a housing and a dividing plate, this dividing plate is divided into upper tube body and lower tube body with hush pipe, this upper tube body and lower tube body are interconnected, and described air intake opening is connected with upper tube body, and described exhausr port is connected with lower tube body; Described inner walls face is provided with a glass wool layer, and described upper tube body and lower tube body are respectively arranged with muffling hole plate.
As a kind of preferred version, described air intake opening is installed on the middle part of upper tube body, and described exhausr port is installed on the lower tube body middle part.
As a kind of preferred version, described dividing plate both ends are provided with respectively a plurality of air holes, and these a plurality of air holes are communicated in upper tube body and lower tube body.
As a kind of preferred version, described muffling hole plate is a plurality of.
As a kind of preferred version, described hush pipe outside is coated with a shockproof pugging.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly: this quieter is by the design of gas flow duct and corresponding muffling hole plate, simultaneously at the hush pipe inside surface glass wool layer is set, is outside equipped with shockproof pugging at hush pipe; This structural design is ingenious, and compact conformation is easy to processing and safeguards; This quieter has good erasure effect, and is economical and practical and do not produce the secondary noise, has market popularization value.

Embodiment
Please refer to shown in Figure 1ly, it has shown the concrete structure of the preferred embodiment of the utility model, and a kind of quieter includes a hush pipe 10, air intake opening 20 and exhausr port 30.
Wherein, this hush pipe 10 includes a housing 11 and a dividing plate 12, these housing 11 internal faces are provided with a glass wool layer 13, the noise that this glass wool layer 13 can absorption of gases produces, these hush pipe housing 11 outsides are coated with a shockproof pugging 14, this shockproof pugging 14 further carries out the noise reduction shock insulation to gas, is conducive to simultaneously eliminate this quieter rear noise because of the vibrations generation is installed.This dividing plate 12 is divided into upper tube body 15 and lower tube body 16 with hush pipe, this upper tube body 15 and lower tube body 16 are interconnected, this upper tube body 15 and lower tube body 16 are respectively arranged with two muffling hole plates 17, and this muffling hole plate 17 can effectively slacken the noise that the gas flow at high speed produces.These dividing plate 12 both ends are provided with respectively a plurality of air holes 18, and these a plurality of air holes 18 are communicated in upper tube body 15 and lower tube body 16.
This air intake opening 20 is arranged at the middle part of upper tube body 15 and is connected with upper tube body 15; Housing section between this air intake opening 20 and the upper tube body 15 is provided with the air admission hole that a plurality of supplied gas enter.This exhausr port 30 is arranged at lower tube body 16 middle parts and is connected with lower tube body 16.Housing section between this exhausr port 30 and the lower tube body 16 is provided with the vent port that a plurality of supplied gas are discharged.
Above-mentioned muffling hole plate 17 can arrange a plurality of according to actual needs.
The use procedure that present embodiment is described in detail in detail is as follows: at first waste gas enters into upper tube body 15 from air intake opening 20; Then waste gas flows to upper tube body 15 two ends, and the air hole 18 by dividing plate 12 two ends behind muffling hole plate 17 enters into lower tube body 16; Discharged by exhausr port 30 behind the last muffling hole plate of waste gas in lower tube body 16.
Design focal point of the present utility model is: this quieter arranges the glass wool layer at the hush pipe inside surface simultaneously by the design of gas flow duct and corresponding muffling hole plate, is outside equipped with shockproof pugging at hush pipe; This structural design is ingenious, and compact conformation is easy to processing and safeguards; This quieter has good erasure effect, and is economical and practical and do not produce the secondary noise, has market popularization value.
The above, it only is preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment makes.
