Description
Technical field
The present invention relates to a kind of structure, especially a kind of noise elimination structure.
Background technique
Structure is complicated for conventional muffler, and production process is cumbersome, takes up a large area, and is unfavorable for the use of the confined space.
Summary of the invention
The object of the present invention is to provide a kind of noise elimination structures.
Above-mentioned purpose is realized by following technical scheme:
A kind of noise elimination structure, including a kind of structure with noise elimination function, the structure is had by what muffling unit formed
The noise elimination structure of zigzag airflow channel.
A kind of noise elimination structure, it is characterized in that: the muffling unit is divided into muffling unit A, muffling unit B and disappears
Sound unit C.
A kind of noise elimination structure, it is characterized in that: the treasure that the muffling unit is made of several pearl stone sound absorbing baffles
Pearl rock sound absorption structure and FC plate sound insulating structure are constituted.
A kind of noise elimination structure, it is characterized in that: the pearl stone sound absorbing baffle is by perlite and inorganic bond
It is stirred to demould after mould shape and dry and manufactured chadless noise elimination structure, and be marked between the noise reduction unit convex
The airflow channel cushion block risen.
A kind of noise elimination structure, it is characterized in that: the perlite sound absorption knot between the pearl stone sound absorbing baffle, described
It is adhesively fixed between structure and the FC plate sound insulating structure and between the muffling unit by Environment-friendlyadhesive adhesive.
The utility model has the advantages that
1. the silencer that the present invention is made of the noise elimination structure with zigzag airflow channel, silencer passes through zigzag air-flow
Channel reaches noise elimination effect using the refraction of sound wave, and acoustic wave filter structure is simple, easy to process, and occupied area is small, effectively solves
Limited space disposes the problem of silencer.
Muffling unit of the invention is divided into muffling unit A, muffling unit B and muffling unit C, and each muffling unit group is become a useful person
Expect identical, shape is different, and muffling unit of different shapes mutually agrees with, and the entirety of noise elimination structure is constituted, so that noise elimination structure is whole
It is neat complete, meet noise elimination effect.
The perlite sound absorption structure and FC sound insulating structure that muffling unit of the invention is made of several pearl stone sound absorbing baffles
It constitutes, the thickness of noise elimination structure can be adjusted by adjusting the thickness and quantity of pearl stone sound absorbing baffle to reach use site
Noise elimination noise reduction requirement.
Between pearl stone sound absorbing baffle, equal benefit between perlite sound absorption structure and FC plate sound insulating structure and between muffling unit
It is adhesively fixed with Environment-friendlyadhesive adhesive, does not influence the noise elimination effect of structure on the basis for guaranteeing stable structure, simultaneously
Environment-friendlyadhesive adhesive is environment friendly and pollution-free, will not generate harm to human body, guarantee the safe handling of silencer and the body of staff
Body health.
Pearl stone sound absorbing baffle of the invention is to be demoulded to dry after mould shape with inorganic bond raw material by perlite
And manufactured chadless noise elimination structure, with apparent density is small, thermal conductivity is small, chemical stability is good, use temperature range is wide, inhales
Wet rate is low and non-toxic and tasteless, fire prevention, sound-absorbing, heat preservation, decoration, antistatic, does not absorb the functions such as lint；It is infused between noise reduction unit
The airflow channel cushion block of some protrusions is integrally formed with perlite abatvoix, and production is simple, easy for installation.
FC sound insulating structure, that is, FC plate of the invention, is the abbreviation of fiber cement board, has big intensity height, plate width, lightweight, prevents
The excellent performances such as fire, waterproof, it is this plate weathering resistance, durable, long service life, safe and environment-friendly, easy for construction.
