Abstract

The utility model discloses a detachable dustproof silencer, including casing, anechoic sheet and dustproof metal mesh, the casing is hollow bilayer structure, the porous sound absorbent of its inside packing, the anechoic sheet is hollow platelike structure, the porous sound absorbent of its inside packing, dustproof metal mesh is fixed in metal crate for the close metal mesh of knitting on, one side of dustproof metal mesh and silencer can be dismantled. The utility model discloses can be applied to the occasion that contains the sugar in air current dust -laden gauge height or the dust. Convenient, the easy washing is dismantled to the dust screen in the silencer, and silencer inner wall zinc -plating perforated plate is easily cleared up, and the performance of making an uproar of falling of silencer receives the influence of dust less. Consequently that has guaranteed the silencer falls the performance of making an uproar for a long time, has prolonged the life of silencer.

Description

A kind of detachable dust-proof silencing apparatus
Technical field
The utility model relates to a kind of silencing apparatus, particularly relates to a kind of detachable dust-proof silencing apparatus.
Background technique
Silencing apparatus reduces the visual plant of air power noise, be usually installed on the air-flow path of all kinds of blower fan (as axial fan, centrifugal fan and mixed flow fan) or enter, exhaust port, to reduce equipment by the noise of air-flow path to air port radiation.
According to noise elimination mechanism, silencing apparatus can be divided into dissipative muffler, reactive muffler, impedance composite muffler and micropunch plate muffler.Dissipative muffler has good medium-high frequency sound absorbing capabilities, and low frequency absorption poor-performing.If but suitably increase thickness and the density of sound-absorbing material, low frequency performance also can improve greatly.Reactive muffler noise elimination frequency band is narrow, be applied to the noise of single peak value pointed strong, Low Medium Frequency sound absorbing capabilities is better, reactive muffler is particularly useful for reducing small pipeline exhaust sound.Impedance composite muffler combines dissipative muffler and reactive muffler feature, be applicable to the occasion that wide band is eliminated the noise, but its structure is more complicated.Micropunch plate muffler has good Low Medium Frequency broadband sound absorbing capabilities, but cost is higher, is mainly applicable to the sqouynd absorption lowering noise in high-cleanness, high place.
Silencing apparatus at present for reducing high-power blower air power noise is mainly resistive or impedance composite muffler.These two kinds of silencing apparatuss are only applicable to air-flow dust concentration lower than 150mg/m 3occasion.If air-flow dust loading is higher, or cause meeting water vapour formation paste containing sugar in dust, dust, with regard to the hole in easy blocking sound-absorbing porous material, even blocks the eyelet on perforated plate, and Sound Elimination Performance of Mufflers reduction was even lost efficacy.
Model utility content
Order of the present utility model is higher for dust loading or contains the air-flow path of sugar in dust, provides a kind of detachable dust-proof silencing apparatus.
The utility model is achieved by the following technical solution:
A kind of detachable dust-proof silencing apparatus, comprise housing, anechoic sheet and dust-proof wire netting, described housing is the double layer construction of hollow, its inner filling porous sound-absorbing material, described anechoic sheet is the platy structure of hollow, its inner filling porous sound-absorbing material, described dust-proof wire netting is that the close wire netting knitted is fixed on metal framework.
Preferably, described housing exterior walls is galvanized steel plain sheet, and inwall is the zinc-plated perforated plate of punching rate 20%-30%, and anechoic sheet outer wall is the zinc-plated perforated plate of punching rate 20%-30%.
Preferably, described sound-absorbing porous material is glass fiber cloth parcel super glass wool.
Described silencing apparatus one sidewall is demountable structure, and establishes V-arrangement draw-in groove, with fixing anechoic sheet.
Described anechoic sheet one end is fixed on muffler shell by rivet, and the other end is wedgelike, is fixed in the V-arrangement draw-in groove of detachable sidewall.
Described dust-proof wire netting is placed in silencing channel, is fixed on the transverse section of silencing apparatus sidewall and anechoic sheet by metal sheeting and screw.
Useful benefit of the present utility model is as follows:
The utility model can be applicable to the occasion containing sugar in the high or dust of air-flow dust loading.Air Filter convenient disassembly, easy cleaning in silencing apparatus, the zinc-plated perforated plate of silencer internal wall is easy to cleaning, and the anti-acoustic capability of silencing apparatus is less by the impact of dust.Therefore ensure that the long-term anti-acoustic capability of silencing apparatus, extend the working life of silencing apparatus.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is the sectional view in Figure 1A-A direction.
Fig. 3 is the sectional exploded view in Figure 1A-A direction.
Embodiment
Contrast accompanying drawing to be below further described the utility model in conjunction with the embodiments.
As shown in Figure 1-Figure 3, a kind of detachable dust-proof silencing apparatus, comprise housing 1, anechoic sheet 2 and dust-proof wire netting 5, housing 1 is the double layer construction of hollow, its inner filling porous sound-absorbing material, anechoic sheet 2 is the platy structure of hollow, its inner filling porous sound-absorbing material, and dust-proof wire netting 5 is that the close wire netting knitted is fixed on metal framework 6.
Housing 1 outer wall is galvanized steel plain sheet, and inwall is the zinc-plated perforated plate 4 of punching rate 25%, and anechoic sheet outer wall is the zinc-plated perforated plate of punching rate 25%.Sound-absorbing porous material 3 is glass fiber cloth parcel superfine glass cotton structure.
Silencing apparatus one sidewall is demountable structure, is fixed in muffler body with screw 7, and this inside sidewalls establishes V-arrangement draw-in groove 8, with fixing anechoic sheet.Anechoic sheet one end is fixed on muffler shell by rivet, and the other end is wedgelike, is fixed in the V-arrangement draw-in groove 8 of detachable sidewall.
Dust-proof wire netting 5 is placed in silencing channel, is fixed on the transverse section of silencing apparatus sidewall and anechoic sheet by metal sheeting 9 and screw 10.
Above-described embodiment of the present utility model is only in order to the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For the those of ordinary skill in described field, the change of other form can also be made on the basis of the above description, cannot give exhaustive to all mode of executions here.Allly belong to the apparent change that the technical solution of the utility model amplifies and be still within protection domain of the present utility model.
