Description
Technical field
The utility model relates to a kind of baffler, is specifically related to a kind of vent muffler for blower.
Background technique
at present, blower is when discharged air, and the noise produced is all generally too fast by high velocity air flowing velocity or air-flow is unstable produced, and this gas high temperature, high pressure, high flow rate, it is the main source of industrial production noise, and its displacement noise intensity is large.Vent muffler guarantees that blower can the vitals of safe operation steady in a long-term, but most of erasure effect is unsatisfactory, meanwhile, owing to being just provided with simple acoustical lining in outer cover, cannot absorbing high-frequency noise, and still cause noise excessive.
Model utility content
Model utility object: in order to solve the deficiencies in the prior art, the utility model provides a kind of vent muffler of blower of good muffling effect.
The purpose of this utility model is realized by such technological scheme, a kind of vent muffler of blower, comprise housing, first orifice plate, plural number the second orifice plate, 3rd orifice plate and super glass wool, described first orifice plate is vertically located at described casing center, described second orifice plate is vertically located in described housing, and ring is located at described first orifice plate surrounding, described 3rd orifice plate is located at bottom described first orifice plate and the second orifice plate, connect described first orifice plate and described second orifice plate, described housing and described first orifice plate, described super glass wool is provided with between second orifice plate and the 3rd orifice plate, described housing upper end is provided with the first cover plate, bottom is provided with the second cover plate, described first orifice plate is intake grill, be connected with blower, described second orifice plate is exhaust outlet.
First orifice plate, the second orifice plate and the 3rd orifice plate are cylindrical, and outside binding has glass cloth.
Described super glass wool and described first orifice plate, the second orifice plate and the relative side of the 3rd orifice plate are provided with glass cloth.
Described glass cloth is the plain weave alkali-free glass cloth of 0.1mm.
Described first cover plate is provided with first through hole corresponding with described first orifice plate, second through hole corresponding with described second orifice plate.
Described second orifice plate is 8.
Described first cover plate and the second cover plate and the first orifice plate, for rivet is fixed between the second orifice plate and the 3rd orifice plate.
Described first cover plate and being welded to connect between the second cover plate and described housing.
Compared with prior art, the vent muffler of a kind of blower involved by the utility model, by arranging eight air outlets, and arranges super glass wool in each air outlet surrounding, high temperature, at a high speed, the gas of high pressure greatly reduces flow velocity by shunting, and reduction noise, its structure is simply novel, and making and installation is convenient, can smooth flow air-flow, prevent additional noise from producing, reduce air-flow velocity, reach the object of sound-deadening and noise-reducing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is the partial schematic diagram of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, clear complete description is carried out to the technological scheme of the utility model embodiment.
As shown in Figures 1 to 3, the vent muffler of a kind of blower that the utility model discloses, be arranged on the exhaust duct of blower, specifically comprise housing 1, be located at first cover plate 2 and second cover plate 3 at housing 1 two ends, in described housing 1, be provided with the first orifice plate 4, second orifice plate 5 and the 3rd orifice plate 6, described housing 1 is provided with super glass wool 7 with between described first orifice plate 4, second orifice plate 5 and the 3rd orifice plate 6.
Particularly, described first orifice plate 4, second orifice plate 5 and the 3rd orifice plate 6 are cylindrical, and outside bundlees the plain weave alkali-free glass cloth 8 having 0.1mm thick, wherein said first orifice plate 4 is vertically located at described housing 1 central position, described second orifice plate 5 ring is located at the surrounding of described first orifice plate 4, described 3rd orifice plate 6 is located at bottom described first orifice plate 4 and the second orifice plate 5, and connect described first orifice plate 4 and the second orifice plate 5, in the utility model, the first orifice plate 4 is intake grill, be connected with blower discharge pipe, described second orifice plate 5 is outlet, air-flow out enters in the first orifice plate 4 from blower discharge pipe afterwards, be diverted in each second orifice plate 5 by the 3rd orifice plate 6 simultaneously and discharge, achieve multiple exit to discharge, thus reduce the flow velocity of air-flow, make air-flow smooth flow.
Described super glass wool 7 and described first orifice plate 4, second orifice plate 5 and the relative side of the 3rd orifice plate 6 also bundle the thick plain weave alkali-free glass cloth 8 of 0.1mm.
