Abstract

The utility model relates to a throttled wind system silencer, in particular to a throttled silencer for lowering noise for low frequency and high frequency noise of a fan on the outlet end of a combined air processing device, which belongs to the technical field of air-conditioning ventilation. The throttled wind system silencer comprises a casing, flexible filler, a net-shaped metal pore plate and a plurality of partition pieces, wherein the partition pieces are connected with the periphery of the inner wall of the casing, and divide the inner cavity of the casing into a plurality of spaces. The throttled wind system silencer is further provided with a plurality of silencing partition pieces which take a certain angle with the air flowing direction in the cavity body on the basis of an original throttled silencer, leads gas to enter the cavity body of the silencer and sends out the gas after doing multi-stage expansion decompression, and silencing by sound-damping material. Compared with a general throttled silencer, the throttled wind system silencer increases the area of sound-absorbing materials, and leads air pressure to weaken in multi stages under the condition without changing the wind direction, thereby effectively eliminating low-frequency noise generated by high-speed rotation of a fan.

Description

A kind of impedance type wind system baffler
Technical field
The utility model relates to a kind of impedance type airduct baffler, and particularly a kind of impedance type baffler that is used for combination type air processing equipment outlet end blower fan low frequency and high frequency noise are carried out noise reduction process belongs to the air conditioner ventilation technical field.
Background technique
Assembled air-conditioner equipment noise is generally the blower fan high speed rotating and produces.Fan noise generally is made up of low frequency and high frequency noise.Noise is propagated by importing and exporting the pipeline that docks with blower fan.In order to reduce noise, generally all need baffler be set in blower fan import and outlet end.Conventional baffler inside all adopts soft filler to come the absorbing high-frequency noise, utilizes the net metal orifice plate that soft filler is fixed on the baffler inwall.The sound absorbing material area is big more, and is just good more to the sound-absorbing effect of high frequency noise.In addition, because soft sound absorbing material is difficult to eliminate the low frequency noise that blower fan produces, so need to enlarge the internal diameter of baffler, expanded when making high pressure draught through baffler, reduce pressure and could eliminate low frequency noise, therefore the internal diameter of conventional baffler is all big than the fan outlet tube footpath, and silencer length is longer.If want to improve erasure effect, then need play the effect of multistage step-down, but occupation area to be excessive at a plurality of bafflers of blower fan outlet series connection, inconvenience is installed.
Summary of the invention
The utility model is developed a kind of novel impedance type airduct baffler at above-mentioned technical problem, and this impedance type baffler floor space is little, easy for installation, good muffling effect.
A kind of impedance type airduct baffler comprises housing, holly strip, soft filler, net metal orifice plate composition.It is characterized in that holly strip arranges at an angle in enclosure interior and air current flow direction, the quantity of holly strip is at least 1, the baffler inner chamber is divided into cavity, the quantity of cavity adds one for holly strip quantity, inlet, the outlet bore that the terminal formation of housing inner chamber air-flow latus rectum is equal to or greater than baffler stretched in holly strip, each holly strip surface is coated with soft filler with shell inner surface, and the net metal orifice plate wraps soft filler in shell inner surface and holly strip surface.
The utility model is by arranging that in muffler shell holly strip changes original single-stage buck impedance type baffler into multistage step-down impedance type baffler, increased the area of soft sound absorbing material, and make under the situation that does not change wind direction that air pressure is multistage to be weakened, thereby eliminate the blower fan high speed rotating effectively and the high and low frequency noise that produces.This baffler erasure effect is obvious, because the air-flow latus rectum is constant, gas-flow resistance is less, is widely used in various combination type air processing equipment outlet and inlet sections.

Among the figure, 1 suction silencer, 2 air-out bafflers, 3 combination type air processing equipmenies, 4 housings, 5 soft fillers, 6 net metal orifice plates, 7 holly strips.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 2,3, impedance type airduct baffler of the present utility model comprises housing 4, soft filler 5, net metal orifice plate 6 and holly strip 7.Holly strip 7 links to each other all around with housing 4 inwalls, holly strip 7 has multi-disc, housing 4 inner chambers are separated be several spaces, each holly strip 7 surface is coated with soft filler 5 with housing 4 internal surfaces, and net metal orifice plate 6 wraps soft filler 5 in housing 4 internal surfaces and holly strip 7 surfaces.
Holly strip 7 of the present utility model can be adopted the 1-5 sheet.Among the embodiment be 3, soft filler 5 is soft sound absorbing material, as asbestos material or sponge material.
Net metal orifice plate of the present utility model can be made by netted steel web plate.
Impedance type airduct baffler of the present utility model is when its intake grill end that is arranged at combination type air processing equipment 3 is suction silencer 1; The air opening end that is arranged at combination type air processing equipment 3 is air-out baffler 2.
