Abstract
The invention discloses a toilet active waste discharging and noise reducing device which comprises a fan. A wind opening in one end of the fan is connected with a cover plate, and a wind opening in the other end of the fan is connected with one end of a flexible wind pipe through a mounting flange. The other end of the flexible wind pipe is connected with a silencer through a mounting flange, and the silencer is connected with a wind inlet. The toilet active waste discharging and noise reducing device has the advantage that the noise of a fan in a toilet of a motor train unit can be effectively lowered.
Description
Technical field
The invention belongs to EMU toilet noise reduction technical field, relate to a kind of toilet initiatively useless row's denoising device.
Background technique
These rail motor set toilet denoising device is applicable to Chinese South car Zhuzhou Electric Locomotive Co rail motor set project.Rail motor set project toilet due to mounting point comparatively far away apart from air-conditioning position, therefore determine by allow toilet carry function that fan realizes initiatively useless row, but after having installed fan exhaust additional, noise is excessive.
Summary of the invention
The object of the present invention is to provide a kind of toilet initiatively useless row's denoising device, solve rail motor set project toilet due to mounting point comparatively far away apart from air-conditioning position, adopt and carry the excessive problem of fan exhaust noise.
The technical solution adopted in the present invention comprises fan, and air port, fan one end is connected with cover plate, and fan the other end air port connects one end of pneumatic hose by mounting flange, and the other end of pneumatic hose connects silencing apparatus by mounting flange, and silencing apparatus connects intake grill.
Further, described pneumatic hose is aluminium bellows.
Further, the length of described pneumatic hose is 7-10 rice, and the bending place of pneumatic hose is 3-5 place.
Further, the pitch of the pipeline inner wall adhesive band gum of described pneumatic hose cotton or the pitch of spraying 3-5mm thickness, the silencing cotton of outer wall adhesive band gum or parcel silencing cotton.
The invention has the beneficial effects as follows and effectively can reduce rail motor set toilet fan noise.
Accompanying drawing explanation
Fig. 1 is toilet of the present invention initiatively useless row's denoising device structural representation.
In figure, 1. fan, 2. cover plate, 3. pneumatic hose, 4. silencing apparatus.
Embodiment
Below in conjunction with embodiment, the present invention is described in detail.
Apparatus of the present invention as shown in Figure 1, comprise fan 1, and air port, fan 1 one end is connected with cover plate 2, and fan 1 the other end air port connects one end of pneumatic hose 3 by mounting flange, and the other end of pneumatic hose 3 connects silencing apparatus 4 by mounting flange, and silencing apparatus 4 connects intake grill.Pneumatic hose 3 is aluminium bellows preferably.The length of pneumatic hose 3 is 7-10 rice, and the bending place of pneumatic hose 3 is 3-5 place.The pitch of the pipeline inner wall adhesive band gum of pneumatic hose 3 is cotton or spray the pitch of 3-5mm thickness, the silencing cotton of outer wall adhesive band gum or parcel silencing cotton.
Reserved grate opening in rail motor set toilet, fan 1 of the present invention is installed on grate opening behind, is connected by cover plate 2.After fan 1 works, can by the gas of inside, toilet according to 144m
3the flow of/h is evacuated to outside toilet, is then transported to bottom train by baffler 4 by the latter linked pneumatic hose 3 of cover plate 2.Because the pitch of pipeline inner wall adhesive band gum is cotton, the silencing cotton of outer wall adhesive band gum, plays certain Noise Reduction, then by the noise reduction of baffler secondary.
The present invention is directed to the noise reduction requirement of rail motor set project toilet.The noise realized transmitting under the useless row of active in rail motor set toilet and car reduces 12db on former noisy basis.Noise reduction measure mainly comprises: 1. initiatively useless row's pneumatic hose 3 lengthens, increase the number of bends of pipeline, give up in toilet the pitch cotton of row's pneumatic hose 3 inwall adhesive band gum or the pitch of spraying 3-5mm, then at silencing cotton or the parcel silencing cotton of aluminium bellows outer wall adhesive band gum; 2. increase silencer.By above means, can realize train under the motion speed of 140km/h ± 5km/h, in car, Tp car toilet measuring point noise figure is reduced to 75db by 87db.
The above is only to better embodiment of the present invention, not any pro forma restriction is done to the present invention, every any simple modification done above mode of execution according to technical spirit of the present invention, equivalent variations and modification, all belong in the scope of technical solution of the present invention.
