Abstract
The invention discloses a silencer. The silencer comprises a silencer shell, wherein an air inlet is formed in the head of the silencer shell and an air outlet is formed in the tail end of the silencer shell; the inner part of the silencer shell is a cavity which is through from left to right; a plurality of acoustic panels are arranged on the upper end of the cavity at intervals; a flow splitting body is arranged on the lower end of the cavity; a fixed plate is arranged on one side of the flow splitting body. The silencer disclosed by the invention has the advantages of simple structure, convenience for utilization and reasonable design; the silencing effect is good due to the mutual effects of the acoustic panels and silencing cotton; and the noise pollution in a working process is reduced effectively.
Description
Technical field
The present invention relates to a kind of silencing apparatus.
Background technique
In large-scale centrifugal blower using process, because process requirement or equipment debugging maintenance etc. need to be by gas exhaust emptying when blower fan works, emptying gas is because it has high pressure, high flow rate produces powerful air-flow exhaust sound, and this type of exhaust sound frequency spectrum is wide, sound level is high, pollution range is large.
By conventional composite type air releasing silencer design method, when the design high pressure large air displacement air releasing silencer because being subject to the noise elimination structure parameter as the restriction of the many factors such as punching rate, aperture, acoustic absorptivity, relative sound impedance, the resonant cavity degree of depth, make that acoustic wave filter structure is oversize, weight is large, the strength and stiffness of complex structure, muffler body required high series of problems, finally causes that manufacture cost is high, less economical, the market competitiveness is low.
Therefore, for addressing the above problem, the spy provides a kind of new technological scheme.
Summary of the invention
The purpose of this invention is to provide a kind of silencing apparatus.
The technical solution used in the present invention is:
A kind of silencing apparatus, comprise suppressor case, the head end of described suppressor case is provided with suction port, tail end is provided with air outlet, the inner cavity for the left and right perforation of described suppressor case, the upper end of described cavity is interval with the polylith insulation board, and the lower end of described cavity is provided with shunting body, and described shunting body one side is provided with fixed plate.
Insulation board be shaped as waveform.
The joint of insulation board and cavity is provided with connecting plate.
Described shunting body is provided with and is equipped with silencing cotton.
Advantage of the present invention is: simple in structure, easy to use, reasonable in design, by the interaction of insulation board and silencing cotton, soundproof effect is good, the noise pollution while effectively reducing work.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein: 1, suppressor case, 2, suction port, 3, air outlet, 4, cavity, 5, insulation board, 6, shunting body, 7, fixed plate, 8, connecting plate, 9, silencing cotton.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, to of the present invention, be described in further detail, this embodiment is only of the present invention for explaining, does not form the restriction to protection scope of the present invention.
As shown in Figure 1, a kind of silencing apparatus of the present invention, comprise suppressor case 1, the head end of suppressor case 1 is provided with suction port 2, tail end is provided with air outlet 3, the inner cavity 4 for the left and right perforation of suppressor case 1, and the upper end of cavity 4 is interval with polylith insulation board 5, the lower end of cavity 4 is provided with shunting body 6, and shunting body 6 one sides are provided with fixed plate 7.
Shunting body 6 is provided with and is equipped with silencing cotton 9.
Advantage of the present invention is: simple in structure, easy to use, reasonable in design, by the interaction of insulation board and silencing cotton, soundproof effect is good, the noise pollution while effectively reducing work.
