Abstract
The utility model is related to a kind of silencing means.It is characterized by comprising sound attenuators, silencing cotton is set in the sound attenuator, input end is arranged in described sound attenuator one end, outlet end is arranged in one end, extension hush pipe is respectively set in the inlet end and an outlet end, the pipeline of air blower enters input end again by the silencing cotton block in sound attenuator from hush pipe, is picked out from the outlet end of sound attenuator.The utility model can play the effect of sound-absorbing noise reduction well, and noise finally out is made to greatly reduce, and reducing the injury because of noise to operating personnel influences, and has preferable practicability.
Description
Technical field
The utility model belongs to equipment technical field, is related to a kind of silencing means.
Background technology
The noise of high-decibel is apparent and specific to the injury of human body, but in our production scenes, because operation needs, portion
Subset will produce out the high noisy more than safety standard, larger injury be caused to on-site personnel, therefore in order to operate
The health of personnel builds a comparatively safe working environment, and necessary safety measure, installation is taken to adapt to environment and operation
Convenient silencing means reduces noise decibel, is necessary to reduce harm.
Utility model content
The purpose of this utility model is the existing above problem in view of the prior art, provides a kind of silencing means, makes most
Noise out greatly reduces eventually, and reducing the injury because of noise to operating personnel influences, and has preferable practicability.
The purpose of this utility model can be realized by following technical proposal：A kind of silencing means, it is characterised in that including
Sound attenuator, the sound attenuator is interior to be arranged silencing cotton, and input end is arranged in described sound attenuator one end, and outlet end, institute is arranged in one end
Extension hush pipe is respectively set in the inlet end and an outlet end stated, the pipeline of air blower enters input end again by disappearing from hush pipe
Silencing cotton block in speaker, picks out from the outlet end of sound attenuator.
The inside of the extension hush pipe sets gradually noise reduction interlayer and silencing cotton layer.
The outside of the silencing cotton block also sets up the sound gobo with its form fit.
The shell of the sound attenuator is ferrous material.
Noise reduction tank inlet is accessed in wind pipe one end that air blower etc. is generated the equipment of noise by the utility model, rear to access
Silencing cotton in sound attenuator is connected to outside after sound-absorbing is handled, then from pipe outlet, and sound attenuator makes closing using iron sheet
Room, small and exquisite and be conveniently operated, device can be placed on the side work of blast apparatus, save space.Should device by producing
Configuration beside the equipment workspace of raw purport noise, flexible and convenient operation, iron sheet outer casing add setting outside acoustical cotton and babinet
The effect of sound-absorbing noise reduction can be played well by extending hush pipe, and noise finally out is made to greatly reduce, reduce because noise to
The injury of operating personnel influences, and has preferable practicability.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the extension hush pipe of the utility model.
Specific implementation mode
It is specific embodiment of the utility model below, the technical solution of the utility model is further described, but
The utility model is not limited to these examples.
A kind of silencing means as shown in Figs. 1-2, including sound attenuator 1, sound attenuator is interior to be arranged silencing cotton 3, sound attenuator one end
Input end 2 is set, and outlet end is arranged in one end, is respectively set in inlet end and an outlet end and extends hush pipe 6, and pipeline 4 is from hush pipe
Into input end again by the silencing cotton block in sound attenuator, outlet 5 is picked out from the outlet end of sound attenuator.Extend the interior of hush pipe
Portion sets gradually noise reduction interlayer 8 and silencing cotton layer 7.The outside of silencing cotton block also sets up the sound gobo with its form fit.Disappear
The shell of speaker is ferrous material.
Noise reduction tank inlet is accessed in wind pipe one end that air blower etc. is generated the equipment of noise by the utility model, rear to access
Silencing cotton in sound attenuator is connected to outside after sound-absorbing is handled, then from pipe outlet, and sound attenuator makes closing using iron sheet
Room, small and exquisite and be conveniently operated, device can be placed on the side work of blast apparatus, save space.Should device by producing
Configuration beside the equipment workspace of raw purport noise, flexible and convenient operation, iron sheet outer casing add setting outside acoustical cotton and babinet
The effect of sound-absorbing noise reduction can be played well by extending hush pipe, and noise finally out is made to greatly reduce, reduce because noise to
The injury of operating personnel influences, and has preferable practicability.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
