Abstract
The utility model discloses an assembled silencer. A metal shell of the whole silencer consists of a left shell, a middle shell and a right shell, which are fixedly connected through connection flanges; between the connection flanges, an asbestos ring is sealed by a liner; sound absorption chips are arranged in the cavities of the left, middle and right shells and respectively fixed on a ring-shaped support; the sound absorption chips in the left, middle and right shells, which are fixed on the ring-shaped support, are formed by 10-20 sheets of porous foam metal material; and the porous foam metal material is of ultra-thick sheet type. As the sound absorption chips are made of the ultra-thick sheet type porous foam metal material, the silencing effect is good; and the porous foam metal material can be recycled without polluting the environment. The assembled silencer has the performance characteristics of being simple in structure, stable for silencing, convenient for dismounting and the like.
Description
Technical field
A kind of assembly type sound suppressor of the utility model, what relate to is to eliminate the noise, sound insulation, absorption techniques field are applied to precipitators, the noise elimination of equipment such as engine.
Background technology
Along with the development of modern city, various housed devices are also increasing, and as lampblack absorber, air-conditioning etc., noise is also come us at one's side thereupon, and the influence of noise on human and harm are a lot, and noise pollution has become the problem of contemporary world.General sound suppressor is with glass wool, rock wool and the microperforated panel sound suppressor as acoustic absorbant on the market now.Because glass wool, rock wool are frangible easy to break, dust spreads in the air and is detrimental to health.And scrap the back and be difficult for handling, environment is polluted.Therefore with the sound suppressor of this material,, easily cause air pollution, human body skin, respiratory tract are damaged its unstable properties though the function of eliminating noise is arranged.Though micropunch plate muffler is difficult for aging, scrap the also recyclable utilization in back, can not cause environmental pollution, sound absorption efficiency is low, frequency is narrow, involves great expense thereby seldom just uses.
The utility model content
The utility model, dissipates because of friction is converted into heat energy with acoustic energy when propagating in porous sound-absorbing material by sound wave in order to overcome above-mentioned defective, reaches the effect of noise elimination from face.Utilize porous foam metal material, metal shell, and two kinds of combinations of materials are become a kind of assembly type sound suppressor of tubular type.Its technology is achieved in that metal shell, porous foam metal material, screw, asbestos seal ring, annular brace is in interior structure, it is characterized in that: whole sound suppressor metal shell divides left shell, middle shell, right casing three is partly formed, be composed of a fixed connection by joint flange between the three, liner sealing asbestos ring between joint flange, left side shell, middle shell, be provided with the sound absorption chip in the right casing cavity, the sound absorption chip is separately fixed on the annular brace, left side shell, middle shell, the sound absorption chip of right casing internal fixation on annular brace is made up of 10～20 porous metal foam metal materials, the fixing left shell in shell two ends in cylindrical, it is conical that right casing is, and porous foam metal material is super sheet formula porous foam metal material.The positive effect of implementing after this technology is: at first be to have overcome above-mentioned defective, because the sound absorption chip uses super sheet formula porous foam metal material, it is effective to eliminate the noise.Recyclable utilization, free from environmental pollution.Have simple in structurely, it is stable to eliminate the noise, performance characteristics such as easy accessibility.
Description of drawings
Fig. 1 looks the sectional structure synoptic diagram for the master of the utility model embodiment;
Wherein, 1-left side shell, 2-annular brace,, shell, 12-screw in the 3-sound absorption chip, 4-joint flange, 5-asbestos seal ring, 6--annular brace, 7-sound absorption chip, 8-sound absorption chip, 9--annular brace, 10-right casing, 11-;
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
See accompanying drawing 1, the end face junction between left shell 1, middle shell 11, the right casing 10 is fixed with joint flange 4, and whole sound suppressor is formed muffler shell by fixedly connected by screw 12, joint flange 4 between left shell 1, middle shell 11, the right casing 10; Be provided with sealing between adjacent two joint flanges 4 with asbestos seal ring 5, be provided with annular brace 2, annular brace 6 in the left shell 1,12 porous metal foam aluminium sheet two ends of uniform sound absorption chip 4 are fixed on annular brace 2, the annular brace 6 with screw 5 respectively; 12 porous metal foam aluminium sheet two ends that are provided with uniform sound absorption chip 4 in the middle shell 11 are fixed on the annular brace 6 with screw 5 respectively; 12 porous metal foam aluminium sheets that are provided with sound absorption chip 4 in the right casing 10 are separately fixed on annular brace 6, the annular brace 9, and it is conical that left shell 1, right casing 11 are, and middle shell 10 is cylindrical, and sound absorption chip 4 adopts super sheet formula porous foam aluminium sheet.
See accompanying drawing 1, whole sound suppressor is by left shell 1, middle shell 11, right casing 10 is formed, 12 porous metal foam aluminium sheets that pass middle shell 11 that fixedly are distributed on the annular brace 6 with screw 12 on the annular brace 6 at middle shell 11 two ends are the sound absorption chip 7 of village's material, in on the shell 11 two ends annular brace 6 respectively with annular brace 2, uniform on the annular brace 6 with screw 12, fixing 12 porous metal foam aluminium sheets is the sound absorption chip 7 of village's material, sound absorption chip 8, again at sound absorption chip 7, be inserted in left shell 1 respectively outside the sound absorption chip 8, right casing 10, left side shell 1, middle shell 11, insert asbestos seal ring 5 between the joint flange 4 of right casing 10, by screw 12 fixedly connected left shells 1, middle shell 11, the joint flange 4 of right casing 10 is formed a kind of assembly type sound suppressor.
When gap exhaust gas discharged and noise enter be conical left shell 1 or right casing 10 enter in during shell 11, waste gas and noise are exaggerated, the pressure of noise and waste gas has been released, and then by the discharging of right casing 10 or left shell 1, reduces by 20～30 decibels of waste gas noises.
