Abstract
The utility model discloses a fan muffler, fan muffler includes pucking and drum kit, pucking and drum kit set up for cylindrical on -edge relatively, pucking and drum kit bottom all are provided with upright support, pucking and drum kit both sides all are provided with the engaging lug, are provided with the connecting hole on the engaging lug, pucking one side disc sets up for the amortization net, and the amortization cotton is filled and presented to inside, be provided with the through -hole in the middle of the drum kit, the through -hole is the loudspeaker form, and drum kit both sides disc is macropore and aperture respectively, and the through -hole surface sets up for the amortization net, and the amortization cotton is filled and presented to inside, muffler and fan air intake connection effectively reduce fan air intake department, noise that large -traffic wind pressure formed, and the clearance, is adjusted because the wind pressure changes the noise problem of formation through adjusting distance between the two as inlet air channel between pucking and the drum kit.
Description
Technical field
The utility model relates to a kind of baffler, particularly relates to the baffler for high pressure positive blower.
Background technique
At present, high pressure positive blower obtains common application, but under the environment that some air-conditioning requirements are higher, and user also can the larger blower fan of choice for use flow.The noise of the blower fan that flow is larger is also relatively large, therefore can not meet environmental requirement, become current inside plants compare can with solve problem.Baffler be stop sound transmission and can use air-flow normal through a kind of device, use baffler to be the important measures eliminating noise in air.Existing baffler is general, and all that is contained in the vent systems of the equipment such as blower fan, plays the effect reducing noise band.Existing muffler for fan has lightweight, that volume is little advantage, although can remove the noise of low frequency, for the large discharge blower fan that noise is larger, noise reduction is not clearly, can not meet the environmental requirement in enterprise's production.
Model utility content
For above-mentioned produced problem, the utility model provides the good high pressure positive blower baffler of a kind of scientific structure, noise reduction.
Muffler for fan, described muffler for fan comprises pucking and drum kit; Described pucking and drum kit are cylindrical to be edge-only oppositely arranged; Up-right support is provided with bottom described pucking and drum kit; Described pucking and drum kit both sides are provided with engaging lug, and engaging lug is provided with attachment hole; Described pucking side disc is that silencing net is arranged, and silencing cotton is filled and presented in inside; Be provided with through hole in the middle of described drum kit, through hole is horn-like, and drum kit both sides disc is respectively macropore and aperture, and through-hole surfaces is that silencing net is arranged, and silencing cotton is filled and presented in inside.
Also comprise link, described link is strip link, and link two ends are provided with attachment hole, and attachment hole matches with the both sides attachment hole of pucking and drum kit respectively and arranges, and is fastened by bolts.
Compared with prior art, the beneficial effect had is: baffler is connected with air inlet, effective reduction air inlet place, the noise that large discharge blast is formed, between pucking and drum kit, gap is as air intake passage, by regulating distance between the two, regulate the noise problem because blast change is formed.
