Description

A kind of combined type particulate muffling unit and the noise reduction building block being combined into by it
Technical field
The present invention relates to one kind to be used for noise elimination structure, and the noise-reducing structure being combined into by particulate muffling unit.
Background technology
At home and abroad on resistance noise reduction material market, generally using sound-absorbing porous material, such as：Mineral wool, superfine glass The inorganic material such as cotton, rock wool；Or the organic material such as cotton, hair, fiber crops, wood fibre.
The dissipative muffler formed with porous material, generally by the noise elimination skeleton using metal, is vertically connected with plate, porous suction Sound material and protection slab composition.Structure is sufficiently complex.But there are two unvanquishable problems for this silencer.First, In wet condition, sound-absorbing porous material can suck large quantity of moisture and decline acoustic absorptivity.At the same time under the action of moisture, inhale Sound material can sink, and influence noise elimination effect.Second, under the action of ultraviolet, sound-absorbing porous material meeting aging, what aging produced Dust, can noise secondary pollution.Especially there is the field of high request in some air qualities, limit the use of inorganic porous material.
The content of the invention
For above-mentioned technical problem, the present invention provides a kind of combined type particulate muffling unit and is combined into by it Noise reduction building block, it has good acoustically effective, while will not be moist, will not cause secondary pollution.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of combined type particulate muffling unit, bag Hollow flat column matrix is included, described matrix is made of particulate acoustic board；Ring shaped slot is provided with described matrix lateral wall；Annular Sound-absorbing material is filled with groove；For matrix when with other matrix combinations, its annular groove can piece together cavity.
As a preferred embodiment, the matrix is positive hexagonal prism shape.The matrix of some positive hexagonal prism shapes can piece together bee The noise elimination building block of Nest architecture.Honeycomb structure is very firm, can guarantee that the firm of acoustic wave filter structure.
As an improvement further including filling matrix, the filling matrix is hollow flat column；Its shape of cross section with The shape that matrix cross sections are diagonally cut is consistent.Fill the edge that matrix is used for split building block so that flush edge. By matrix with filling being complementary to one another for matrix, various building blocks of different shapes can be pieced together.
As a preferred embodiment, the flow area of described matrix accounts for the 45% ~ 53% of whole cross section.Not only ensure to divulge information, but also really Protect noise reduction.
The invention further relates to a kind of noise elimination building block, it is put together by a combinations of the above muffling unit that declines.
As an improvement the noise elimination building block section is circular, triangle or rectangle, by glue sticking or it is cementitious and Into.
The invention has the beneficial effects that：
1st, structure very simple.It is of low cost.
2nd, it is very friendly to environment.Do not produce secondary pollution.
3rd, good weatherability.Acoustic absorptivity stability is good.It is not affected by environment.Long-time service can ensure to disappear with good Sound effective value.
4th, due to using modular construction.The muffling unit of two kinds of specifications, with regard to various acoustic wave filter structures can be combined into.Example Such as：Circular, rectangle and other irregular shapes.
5th, transport and store in a warehouse very convenient.Construction is also very convenient.
6th, using built in air chamber or it is interior fill out sound-absorbing material after, its acoustic absorptivity increases significantly.

Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.
" particulate acoustic board " of the present invention is recorded in the patent of invention of the applicant's application《A kind of particulate acoustic board and Preparation method》In, its Application No. 2014103477351, it includes binding agent and sound absorption particle, sound absorption particle exterior surface covering One layer binder, the dihedral coefficient for covering the sound absorption particle after binding agent are less than 1.3；It is described sound absorption particle include skeleton particle and Filler particles, skeleton particle form sound absorption framework, and the hole that filler particles enter between skeleton particle forms sound absorption gap, sound absorption The average diameter of gap cross section is 0.07mm.
As shown in Figures 1 to 6：
The present invention includes hollow flat column matrix, and described matrix is made of particulate acoustic board；On described matrix lateral wall It is provided with ring shaped slot；Sound-absorbing material is filled with annular groove；When with other matrix combinations, its annular groove can piece together matrix Cavity.Matrix is positive hexagonal prism shape.Including filling matrix, the filling matrix is hollow flat column；Its shape of cross section with The shape that matrix cross sections are diagonally cut is consistent.The flow area of matrix accounts for the 45% ~ 53% of whole cross section.Hexahedron Wall thickness is about 10-12mm.When two hexahedrons combine, its gap is about 30mm.
By adjusting different-diameter particulate, the inside and outside micro-pore and hole connected can be formed in noise elimination block interiors, when When sound wave is by the endoporus of noise elimination building block, sound wave can enter inside microparticle material along hole, cause air molecule in gap Vibration.Due to the viscosity resistance and air molecule of air and the friction of pore wall, acoustic energy is converted into thermal energy and is lost.Sound-absorbing material It is sealed in the cavity being put together by the annular groove on two matrixes so that moisture content can not soak, and avoid acoustic absorptivity from declining； In addition ultraviolet direct projection is it also avoid, avoids sound-absorbing material aging.And even if there is a degree of aging to form dust, It is not easy to reveal.
Declined the noise elimination building block that a muffling unit is put together by combinations of the above the invention further relates to a kind of.Disappear some Sound unit is stitched together by modes such as bonding agent or cement, forms variously-shaped noise elimination building block, its section such as circle, three Angular or rectangle.Noise elimination building block is the elementary cell for forming silencer again.The matrix of positive hexahedron is very easy to composite assembly, Form the building block of honeycomb type.Its marginal portion can be filled using matrix is filled, and fill matrix cross sections shape and matrix The shape that cross section is diagonally cut is consistent, that is, an isosceles trapezoid.Just between filling and two matrixes so that side Edge is smooth.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
