Abstract
The invention relates to a novel labyrinth silencer, which is characterized in that: a U-shaped grid cover B, a gird cover D and a grid cover F are arranged at a tail-end step of a sound inlet pipe and fixed by a plug cover, and the sound inlet pipe and the step are closely connected with the gird cover B, the grid cover D, the grid cover F and the plug cover; a plurality of damping holes are arranged between two steps of the sound inlet pipe, a grid cover A, a grid cover C, a grid cover E and an outer housing are arranged at the top step of the sound inlet pipe and closed by a nut cap, and the sound inlet pipe, the step, the grid cover A, the grid cover C, the grid cover E, the outer housing and the nut cap are connected; meanwhile, a plurality of Z-shaped labyrinth spaces which are communicated are formed among the sound inlet pipe, the grid cover A, the grid cover B, the grid cover C, the grid cover D, the grid cover E, the grid cover F and the outer housing; and a silencing pipe cover is connected with a U-shaped port of the outer housing, and a space which is communicated with the Z-shaped labyrinth spaces is formed at the inner side of the silencing pipe cover and the outer side of the grid cover F and communicated with a silencing hole.
Description
Technical field
The present invention relates to a kind of silencing apparatus, particularly a kind of novel labyrinth silencing apparatus belongs to the silencing apparatus technical field.
Background technique
At present, the silencing apparatus of market sale all is to adopt welding procedure basically, with suction tude, damp tube, pressing chamber, expansion chamber, the outlet pipe fixed connection of silencing apparatus, forms the stationary structure silencing apparatus.This silencing apparatus exists complex process, and productivity is low, also is unfavorable for inner carbon distribution cleaning simultaneously and safeguards that working life is short, brings inconvenience to the user.
Summary of the invention
The objective of the invention is to provide a kind of: technology is simple, productivity is high; And can make things convenient for its internal cleaning and maintenance; Improve a kind of novel labyrinth silencing apparatus in working life, overcome existing silencing apparatus complex process, productivity is low and is unfavorable for defect of insufficient such as inner carbon distribution cleaning and maintenance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of novel labyrinth silencing apparatus; It is formed by advancing sound pipe, nut, outer casing, E grid cover, C grid cover, A grid cover, B grid cover, D grid cover, F grid cover, blanking cover, hush pipe lid, step, damping hole, sound inlet, bloop; The mazy type silencing apparatus has into sound pipe; Pack at the terminal step place of advancing the sound pipe " U " shape B grid cover, D grid cover, F grid cover, fix with blanking cover, making into, sound pipe, step closely are connected with B grid cover, D grid cover, F grid cover, blanking cover; Advancing between sound pipe two steps some damping holes are set, the A grid cover of packing at the top stage place of advancing the sound pipe, C grid cover, E grid cover, outer casing, closing with nut, making into, sound pipe, step, A grid cover, C grid cover, E grid cover, outer casing, nut connect; Also make simultaneously and into form several spaces, " Z " shape labyrinth that communicate between sound pipe, A grid cover, B grid cover, C grid cover, D grid cover, E grid cover, F grid cover and outer casing; " U " shape mouth place of hush pipe lid outer casing connects, and the inboard of hush pipe lid forms a space that communicates with space, " Z " shape labyrinth with the outside of F grid cover, and its space communicates with bloop.
Noise reduction principle of the present invention and noise reduction process are: and the employing of noise reduction principle " damping---compression---expansion---energy consumption ", combine " sound wave backpropagation, energy is cancelled out each other " principle to form simultaneously.The noise reduction process: sound wave gets into into sound pipe; Get into the space of forming between A, B, C, D, E, F grid cover, " Z " shape labyrinth through damping hole; Sound wave is compressed, carries out in space, " Z " shape labyrinth through the sound wave of overcompression that 7 backpropagations are in service is repeatedly cancelled out each other, in sound wave gets into the space that F grid cover and outer casing form, obtain expansion after; Discharge through bloop, reach the noise reduction purpose of sound wave a little less than by strong commentaries on classics.
Beneficial effect of the present invention is: in cleaning and servicing operations; Loosen nut and blanking cover make outer casing A, B, C, D, E, F grid cover and hush pipe lid, advance between the sound pipe to form single-piece, do not connect mutually; Just can directly remove inner carbon distribution, prolong silencing apparatus working life.The split type manufacturing of single-piece, not only technology is simple, productivity is high; And can make things convenient for its internal cleaning and maintenance, improve working life.
