Abstract
The utility model provides an exhaust muffler structure. A front resonant cavity is arranged in an inner cavity of a cylinder body. A muffler band is arranged on a side of the front resonant cavity. A spiral muffler band is connected to a side of the muffler band. The spiral muffler band is equipped with a micro-pore plate. The micro-pore plate is connected with a rear resonant cavity. Choke blocks are installed below and above the front resonant cavity, the muffler band, the spiral muffler band and the rear resonant cavity symmetrically. An exhaust pipe is installed on the chock blocks. The exhaust pipe is fixed on the cylinder body.
Description
Technical field
The utility model relates to a kind of muffler pipe structure, and particularly a kind of exhausting silencer tubular construction, belong to plant equipment noise elimination technique field.
Background technology
As everyone knows, present noise-cancelling theory in sector applications such as chemical industry, oil, metallurgy, electric power, automobile, boilers mainly contains aspect expenditure and pressure aperture resistance tail two, common sound suppressor form has the compound of expenditure and pressure sound suppressor, aperture resistance tail sound suppressor and both, and above three kinds of sound suppressors have the following disadvantages separately: 1, resistance is larger; 2, complex structure; 3, aperture easily stops up.
Summary of the invention
The purpose of this utility model is: a kind of simple in structure, resistance is little, sound attenuation hole be difficult for to stop up, soundproof effect is good, versatility is wide a kind of exhausting silencer tubular construction is provided, overcomes the existing above-mentioned defect of existing sound suppressor.
the technical scheme that its technical matters that solves the utility model adopts is: a kind of exhausting silencer tubular construction, it is by gas outlet, cylindrical shell, front resonant cavity, choke block, eliminate the noise and be with, spiral is eliminated the noise and is with, microwell plate, rear resonant cavity forms, described exhausting silencer tubular construction is provided with a front resonant cavity in the inner chamber of cylindrical shell, a side at front resonant cavity is provided with a noise elimination band, a side at the band of eliminating the noise is connected with spiral noise elimination band, spiral is eliminated the noise to be with microwell plate is installed, on microwell plate, be connected with rear resonant cavity, at front resonant cavity, eliminate the noise and be with, the laterally zygomorphic choke block that is equipped with of spiral noise elimination band and rear resonant cavity, one gas outlet is installed on choke block, by gas outlet be fixed on cylindrical shell above.
Principle of work of the present utility model: the utility model has been abandoned traditional exhaust emptying noise elimination theory fully, flow rotation viscous principle in application, when air-flow from the passage of gas outlet through out-of-date, be in the middle of gas outlet the front resonant cavity on peace and inwall and rear resonant cavity except air-flow being played corresponding inhibition, simultaneously, make air-flow in center and the outer rotation that produces opposite direction, thereby play, weaken and the energy that has reduced air-flow, reach the purpose of sound-deadening and noise-reducing.
The beneficial effects of the utility model: the utility model is due to after adopting such scheme, have advantages of that good muffling effect, resistance are less, simple structure, safe and reliable, accommodation is wide, failure rate is lower, non-maintaining, also has advantages of simultaneously exhaust and the two kinds of functions of eliminating the noise.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, structure of the present utility model is described further.
Fig. 1 is structure principle chart of the present utility model.
Shown in figure: 1, gas outlet; 2, cylindrical shell; 3, front resonant cavity; 4, choke block; 5, eliminate the noise and be with; 6, spiral is eliminated the noise and is with; 7, microwell plate; 8, rear resonant cavity.
