Abstract

The utility model discloses a silencing device for a pneumatic water pump, which comprises the following components: a body, a silencing chamber, an air inlet and an air outlet. The air inlet is provided at the bottom of the body. The air outlet is provided at the top of the body. The silencing chamber is equipped at the inner wall of the body and comprises a silencing noise-reducing block and a silencing cover. The silencing noise-reducing block is closely connected with an inner wall of the body. The silencing cover is connected with outside of the silencing noise-reducing block. Through the above mode, the silencing device for the pneumatic water pump according to the utility model is additionally provided with the silencing chamber on the inner wall of the body. Furthermore the silencing noise-reducing block is filled in the silencing chamber for better reducing the energy of the noise, thereby improving noise reduction effect and furthermore improving operation efficiency of the pneumatic water pump.

Description

A kind of silencer that is used for wind-driven water pump
Technical field
The utility model relates to the wind-driven water pump technical field, particularly relates to a kind of silencer that is used for wind-driven water pump.
Background technique
Wind-driven water pump can produce a large amount of noises in the course of the work, has greatly influenced operator's physical and mental health, has caused environmental pollution.
In order to reduce noise pollution, generally noise insulation equipment can be installed on noise source, existing muffling device generally adopts aperture crowd exhausting silencer technology.This type muffling device all can not reach the requirement of domestic and international related standards at the comparatively abominable scene of operating conditions such as mine, the noise elimination weak effect has influenced workmen's physical and mental health, has also influenced the working efficiency of wind-driven water pump simultaneously.
The model utility content
The technical problem that the utility model mainly solves provides a kind of silencer that is used for wind-driven water pump, can subdue noise energy well, thereby obtains noise reduction preferably.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of silencer that is used for wind-driven water pump is provided, comprises: body, silencing cavity, intake grill and exhaust outlet; Said intake grill is arranged on the body bottom; Said exhaust outlet is arranged on the body top, and said silencing cavity is arranged on the inner body wall, and said silencing cavity comprises sound-deadening and noise-reducing piece and silencer cover; Said sound-deadening and noise-reducing piece closely is connected with inner body wall, and said silencer cover is connected the sound-deadening and noise-reducing piece outside.
In preferred embodiment of the utility model, said silencing cavity is an open cavity.
In preferred embodiment of the utility model, be interconnected between said intake grill, exhaust outlet and the body.
In preferred embodiment of the utility model, said sound-deadening and noise-reducing piece is an elastomer, and the cross section of said sound-deadening and noise-reducing piece is parallelogram, triangle or trapezoidal.
In preferred embodiment of the utility model, said sound-deadening and noise-reducing piece is sound-absorbing sponge or sound-absorbing rubber.
The beneficial effect of the utility model is: the utility model has increased silencing cavity on inner body wall; And in this silencing cavity, filled the sound-deadening and noise-reducing piece; Can subdue noise energy well, thereby obtain noise reduction preferably, further improve the working efficiency of wind-driven water pump.
Description of drawings
Fig. 1 is the structural representation that the utility model is used for silencer one preferred embodiment of wind-driven water pump;
Fig. 2 is the structural representation of cross section of the sound-deadening and noise-reducing piece of the utility model silencer of being used for wind-driven water pump;
The mark of each parts is following in the accompanying drawing: 1, body, 2, silencing cavity, 3, intake grill, 4, exhaust outlet, 5, the sound-deadening and noise-reducing piece, 6, silencer cover.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 and Fig. 2, the utility model is embodiment comprise:
A kind of silencer that is used for wind-driven water pump comprises: body 1, silencing cavity 2, intake grill 3 and exhaust outlet 4.Said intake grill 3 is arranged on body 1 bottom, and said exhaust outlet 4 is arranged on body 1 top.Said silencing cavity 2 is arranged on body 1 inwall, and said silencing cavity 2 comprises sound-deadening and noise-reducing piece 5 and silencer cover 6, and said sound-deadening and noise-reducing piece 5 closely is connected with body 1 inwall, and said silencer cover 6 is connected sound-deadening and noise-reducing piece 5 outsides.
Said silencing cavity 2 is an open cavity, is interconnected between said intake grill 3, exhaust outlet 4 and the body 1, can play good sound deadening, has increased the effect of sound-deadening and noise-reducing greatly.
Said sound-deadening and noise-reducing piece 5 is an elastomer, is sound-absorbing sponge or sound-absorbing rubber, and the cross section of said sound-deadening and noise-reducing piece 5 is parallelogram, triangle or trapezoidal.Sound-deadening and noise-reducing piece 5 is an elastomer, when it contacts with noise source, can play the effect of noise reduction or vibration damping, also is easy to simultaneously install.
The silencing cavity 2 that the noise that the wind-driven water pump working procedure produces gets into this silencer along with air-flow from intake grill 3; Being arranged on silencing cavity 2 inner sound-deadening and noise-reducing pieces 5 starts working; When noise source contacts with it; Absorbed by sound-deadening and noise-reducing piece 5, discharge from exhaust outlet 4 again through the air-flow that sound-deadening and noise-reducing is handled.
The beneficial effect of the utility model is: increased silencing cavity 2 on body 1 inwall; And in this silencing cavity 2, filled sound-deadening and noise-reducing piece 5; Can subdue noise energy well, thereby obtain noise reduction preferably, further improve the working efficiency of wind-driven water pump; This sound-deadening and noise-reducing piece 5 is an elastomer, when it contacts with noise source, can play the effect of noise reduction or vibration damping, also is easy to simultaneously install.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
