Abstract
The utility model relates to a silencer housing structure. The silencer housing structure comprises outer plates, an end panel, a pore plate, an inner support framework and a flange, wherein four outer plates are arranged outside the inner support framework respectively, the pore plate is arranged on the inner support framework, silencing cotton is arranged between the pore plate and the outer plates, the flange is connected outside the end panel, and the outer plates and the end panel are bent to form a 90-degreee angle and integrally structured; a flow deflector is further vertically arranged at the middle position of the inner support framework; a wrap angle is arranged on an angle formed by every two connected outer plates and the end panel, and the wrap angle is fixed by a fixing bolt. According to the silencer housing structure disclosed by the utility model, the outer plates and the end panel are integrally-formed structure, and moreover, one wrap angle is added at each angle, thus a silencer is better in sealing performance; moreover, the silencer is quite simple and beautiful in structure, better in the acted silencing effect, and more convenient to install.
Description
Technical field
The utility model relates to a kind of silencing apparatus, relates in particular to a kind of muffler shell structure of using for ventilation duct sound-attenuating systems such as building, building and tunnels.
Background technique
Traditional silencing apparatus, adopts seaming mode joint forming at panel and end face, although this structure is simple, but in performance, there is certain leaking out, and seaming beading is not upright to overall appearance, on each angle, has air leakage phenomena simultaneously, and safeguard that installation neither be very convenient.
Summary of the invention
The utility model provides a kind of soundproof effect good, simple in structure in order to address the above problem, muffler shell structure easy to maintenance.
In order to address the above problem, the technical solution adopted in the utility model is: a kind of muffler shell structure, comprise outside plate, end plates, orifice plate, inner support skeleton and flange, described inner support skeleton is respectively equipped with four outside plates outward, described inner support skeleton is provided with orifice plate, and between orifice plate and outside plate, be provided with the cotton of eliminating the noise, described end plates are externally connected with flange, and described outside plate and end plates bending are an angle of 90 degrees and are integrated; Described inner support skeleton neutral position is vertically also provided with guide plate; The angle that described two outside plates that are often connected and end plates form is provided with a cornerite, and cornerite is fixed by fixed bolt.
Better for the wind effect playing, described zinc-plated orifice plate two is also separately installed with a wind-guiding head, and wind-guiding head is triangle body structure or semi-circular structure.
Better for soundproof effect, described guide plate includes zinc-plated orifice plate and the cotton of eliminating the noise, and described guide plate is to become a structural cavities by the zinc-plated orifice plate in two of left and right with two ends wind-guiding capitiform, and it is cotton in the middle of cavity, to be filled with noise elimination.
Better for the sealing effect playing, described cornerite is that galvanized steel plain sheet integration mold is compressing.
For cornerite is fixed better, described fixed bolt is self-plugging rivet.
Of the present utility model producing effect is: by by outside plate and being made of one of end plates shaping structure, and at each angle, increased a cornerite, so not only make the sealability of this silencing apparatus better, and structure is also very simple, attractive in appearance, the soundproof effect playing is better, installs more convenient.
