Technical Field
The utility model relates to a connect the elbow field, more specifically the utility model relates to a formaldehyde-free amortization elbow that says so.
Background
At present, the traditional silencing elbow is used for silencing at the turning position of a pipeline, and a material in a sound absorption layer is an ultra-fine glass wool covered galvanized steel wire mesh so as to reinforce an original structure and enable the silencing material not to be easily damaged and to be blown away by air flow. Meanwhile, the outer wall is made of galvanized steel plates, the outer side of the elbow is made into a right angle, the inner side of the elbow is in a bent shape, and the elbow has small resistance and has large noise elimination effect on high and medium frequencies.
The binder of the traditional sound absorption material glass wool and the superfine glass wool contains substances harmful to human bodies, such as formaldehyde, phenolic resin, urea and the like, and the phenolic resin is easy to volatilize the formaldehyde and can cause serious consequences to the health of the human bodies.
The traditional sound absorption material glass wool and the superfine glass wool have weak durability and are not suitable for quiet and comfortable houses, commercial buildings and industrial buildings which have higher and higher requirements on the material of the ventilation pipeline system at present.
Therefore, how to provide a bend which is formaldehyde-free and has a good noise reduction effect is a problem that needs to be solved urgently by the technical personnel in the field.
SUMMERY OF THE UTILITY MODEL
In view of this, the present invention provides a formaldehyde-free noise reduction elbow to solve at least one of the above technical problems in the prior art to a certain extent.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a formaldehyde-free muffling elbow, comprising: an elbow housing and a curved plate;
openings are formed at two adjacent ends of the elbow shell, and a plurality of parallel flow distribution convex strips are arranged at the two openings;
two side surfaces of the curved plate are provided with sound attenuation plate layers; the bent plate is equipped with the polylith, every the both ends of bent plate correspond respectively to be installed two on the above-mentioned reposition of redundant personnel sand grip that the opening corresponds, will the inner chamber of elbow casing is separated for a plurality of arc chambeies.
According to the technical scheme, compare with prior art, the utility model discloses a formaldehyde-free amortization elbow divides into a plurality of cavities with the elbow inner chamber through setting up the polylith bent plate, and the face of bent plate is amortization sheet layer structure, has increased the amortization area to promote noise cancelling effect.
Preferably, in the formaldehyde-free silencing elbow, the inner wall of the elbow shell opposite to the curved plate is an arc-shaped wall, so that the air flow passing ability can be improved, and the collision power can be reduced.
Preferably, in foretell no formaldehyde amortization elbow, be equipped with the cavity in the lateral wall of elbow casing, pack the amortization cotton in the cavity, this scheme can promote sound absorbing effect.
Preferably, in foretell no formaldehyde amortization elbow, be equipped with the cavity in the bent plate, pack the amortization cotton in the cavity, this scheme can further promote the sound effect of inhaling.
Preferably, in a formaldehyde-free silencing elbow of the above, the silencing protrusion is disposed on the inner wall of the elbow shell, so that the effect of disturbing the airflow can be achieved through the protrusion structure.
Preferably, in the formaldehyde-free silencing elbow, the silencing protrusions are arranged on both side surfaces of the curved plate.
Preferably, in the formaldehyde-free silencing elbow, the silencing protrusion is of a protrusion structure with a rough surface and multiple holes; this scheme can further promote the sound effect of inhaling.
