Abstract
The utility model relates to a silencer for a perforated plate. The silencer comprises the perforated plate and an air guide device and is characterized in that the outer wall of the perforated plate is provided with sound absorption cotton; a corrosion resisting plate is arranged outside the sound absorption cotton; and the air guide device is adhered to the perforated plate through adhesive. Composite structural design is adopted, and high-intensity, light and corrosion-resistant glass reinforced plastic is matched, so the silencer can be assembled quickly, has a simple structure, is low in drag coefficient and good in sound insulation effect.
Description
Technical field
The utility model relates to a kind of baffler, especially a kind of perforated plate baffler.
Background technique
The outlet and inlet implication of prior electric machine stream noise absorber to be adopted resistive, resistance, micropunch or rents resistance multiple tube baffler; Complex structure, make loaded down with trivial details, the pressure loss big, unit length erasure effect weak, the monomer product quality is heavy; Therefore, have certain disadvantages.
The model utility content
The technical problem that the utility model will solve is: a kind of simple, easy to maintenance, reliable perforated plate baffler of making is provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of perforated plate baffler; Comprise perforated plate and airflow guiding device; It is characterized in that: described perforated plate outer wall is provided with acoustical cotton; Described acoustical cotton arranged outside has corrosion-resistant plate, and described airflow guiding device is bonded on the perforated plate through adhesive.Described airflow guiding device is processed by glass fibre reinforced plastic material.
The beneficial effect of the utility model is, solved the defective that exists in the background technique, owing to taked composite structural design, and be equipped with high tenacity, light weight, corrosion resistant glass fibre reinforced plastic material, assembling, simple in structure fast, resistance coefficient is low, and soundproof effect is good.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the preferred embodiment of the utility model;
Among the figure: 1, perforated plate; 2, corrosion-resistant plate; 3, acoustical cotton; 4, airflow guiding device; 5, flange.
Embodiment
Combine accompanying drawing and preferred embodiment that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of perforated plate baffler as shown in Figure 1; Comprise perforated plate 1 and airflow guiding device 4, the outer wall place of said perforated plate 1 is provided with glass fibre acoustical cotton 3, and; The both sides of said muffler assembly are provided with adpting flange 5; Simultaneously, also be provided with anti-UV plate 2 in the outside of said glass fibre acoustical cotton 3, said glass fibre acoustical cotton 3 fits tightly together with said perforated plate 1 under the parcel of said anti-UV plate 2.
The just embodiment of describing in the above specification of the utility model; The various fleshes and bloods that illustrate not the utility model constitute restriction; Under the those of ordinary skill of technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from the essence and the scope of model utility.
