Abstract
The utility model discloses a stagger type exhaust muffler. The stagger type exhaust muffler comprises a cylinder body, a flange gas inlet, a flange gas outlet, a base and a rectangular muffler piece in an empty abdominal cavity shape; the flange gas inlet and the flange gas outlet are arranged at the two ends of the cylinder body respectively; the cylinder body is fixed on the base; the rectangular muffler piece in an empty abdominal cavity shape is transversely arranged in the cylinder body; the rectangular muffler piece in an empty abdominal cavity shape consists of a tapered wind deflector, a stainless steel framework and sound absorption plates; the sound absorption plates are mounted on the stainless steel framework; the tapered wind deflector is arranged at the top of the rectangular muffler piece; and sound-absorption micro-pores are formed on the sound absorption plates in a stagger manner. During operation, gas enters the cylinder body through the flange gas inlet, becomes stable after passing the tapered wind deflector and is discharged from the flange gas outlet after being treated by the rectangular muffler piece in an empty abdominal cavity shape. The stagger type exhaust muffler has the advantages of simple structure, great sound elimination amount, good sound elimination effect and the like, is convenient to mount and is smooth in exhaust.
Description
Technical field:
The utility model relates to a kind of air exhaust muffler device, relates in particular to a kind of stagger arrangement formula exhaust silencer.
Background technique:
The high intensity noise that high temperature, high pressure and the high speed exhaust emptying of industrial departments such as electric power, oil, chemical industry, metallurgy, weaving is produced has a strong impact on operator's physical and mental health.The anechoic sheet that uses in the exhaust silencer at present is to adopt metallic material to be made; Manufacture cost is used under environment mal-conditions such as steel works, colliery factory, mine than higher, can not in time clear up the inner rubbish of muffler section; Behind the long-play; Aperture on the sheet metal is prone to stop up, and causes the noise elimination effect of silencing apparatus to reduce and disappearance, causes shorten the working life of bloop; Another kind is the cotton of eliminating the noise, and after the long-time open-air operation, its acoustically effective reduces; Later its sound-absorbing material of water contacting can go bad rotten, influences acoustically effective, reduces the working life of noise reduction cotton greatly; The cotton fibrous structure that produces of eliminating the noise has certain injury to healthy; Can produce secondary pollution, be unfavorable for people's health, can not satisfy the relative national standards requirement.
The model utility content:
The utility model is to the deficiency of existing technology, and the stagger arrangement formula exhaust silencer of a kind of simple in structure, effective, lower resistance of eliminating the noise, low cost of manufacture, long service life is provided.
For realizing above purpose, the technological scheme that the utility model adopts is:
Stagger arrangement formula exhaust silencer is made up of cylindrical shell, flange suction port, flange air outlet, base, empty stomach chamber type rectangle anechoic sheet; The cylindrical shell two-port respectively is provided with flange suction port and flange air outlet, and cylindrical shell is fixed on the base, is provided with horizontal placement chamber type rectangle anechoic sheet on an empty stomach in the cylindrical shell.
Said empty stomach chamber type rectangle anechoic sheet is made up of taper air guide sleeve, stainless steel insert and acoustic board, and acoustic board is installed on the stainless steel insert, and the top is provided with the taper air guide sleeve;
Said acoustic board is provided with the sound absorption micropore, is the stagger arrangement formula and arranges;
Said acoustic board adopts haydite or flint clay aggregate to process;
The utility model is compared with existing exhaust silencer, and acoustic board adopts haydite or flint clay aggregate, and is molded through adding the water stirring extruding; Need not sintering; But energy saving 80% reduces manufacture cost, can not produce secondary pollution; Reach effect in energy saving and environmental protection, long-play under the environment harsh conditions; Acoustic board is provided with the sound absorption micropore, is the stagger arrangement formula and arranges, and makes distribution of gas even, reaches the good purpose of acoustically effective, when anechoic sheet cavity distance is 0mm, and noise reduction coefficient NRC=0.7; When the cavity distance was 0-10mm, noise reduction coefficient NRC=0.8 made ambient noise meet country's " industrial enterprise's noise sanitary standard ", can be widely used in industries such as airspace engine test bay, power plant, steel works, colliery factory, subway, mine, gas turbine.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is Figure 1A-A sectional view;
Fig. 3 is the utility model chamber type rectangle anechoic sheet structural representation on an empty stomach;
Embodiment:
Like Fig. 1, Fig. 2, shown in Figure 3, stagger arrangement formula exhaust silencer is made up of cylindrical shell 1, flange suction port 2, flange air outlet 3, base 4, empty stomach chamber type rectangle anechoic sheet 5, taper air guide sleeve 6, stainless steel insert 7, acoustic board 8, sound absorption micropore 9; Cylindrical shell 1 two-port respectively is provided with flange suction port 2 and flange air outlet 3, and cylindrical shell 1 is fixed on the base 4, is provided with horizontal placement chamber type rectangle anechoic sheet 5 on an empty stomach in the cylindrical shell 1; Said empty stomach chamber type rectangle anechoic sheet 5 is made up of taper air guide sleeve 6, stainless steel insert 7 and acoustic board 8, and acoustic board 8 is installed on the stainless steel insert 7, and the top is provided with taper air guide sleeve 6; Said acoustic board 8 is provided with sound absorption micropore 9, is the stagger arrangement formula and arranges.
During work, gas gets into the cylindrical shells 1 from flange suction port 2, gas through taper air guide sleeve 6 after, gas become steadily, gas is through after chamber type rectangle anechoic sheet 5 noise reduction process on an empty stomach, 3 discharges from the flange air outlet.
The utlity model has advantages such as simple in structure, easy for installation, that sound deadening capacity very big, noise elimination is effective, exhaust is unobstructed, can satisfy the requirement of relative national standards, have great promotional value.
