Abstract
The utility model discloses a kind of novel current stabilization noise reducing muffle, comprise housing, the bottom of housing arranges and stretches into the choker-line in housing, and choker-line is set with injection into orbit pipe outward, the upper end of housing arranges a tubular current stabilization denoising device, and rainhat is set above housing; Described current stabilization denoising device directly identical with housing internal diameter, is mutually to be intersected and stacked the right cylinder combining by polylith corrugated plate, and corrugated plate is vertically placed, and forms the passage of regular shape between the crest of adjacent corrugated plate and trough.The utility model is rational in infrastructure, is a kind of new and effective exhaust box, and anti-acoustic capability improves 40%-60% than old-fashioned exhaust box, and has rainproof function.
Description
Technical field
The utility model relates to a kind of exhaust box.
Background technology
At present, although factory's exhausr port is provided with exhaust box, after actual measurement, find, the noise reduction value of a lot of exhaust boxs can not meet the requirement of Standard of Environmental Noise, especially outstanding when particularly operating mode is unstable.Life on workman and periphery resident brings a lot of impacts.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the novel current stabilization noise reducing muffle that noise-reduction is effective.
The purpose of this utility model is also to provide a kind of novel current stabilization noise reducing muffle with rainproof function.
Technical solution of the present utility model is:
A novel current stabilization noise reducing muffle, is characterized in that: comprise housing, the bottom of housing arranges and stretches into the choker-line in housing, and choker-line is set with injection into orbit pipe outward, and the upper end of housing arranges a tubular current stabilization denoising device, and rainhat is set above housing; Described current stabilization denoising device directly identical with housing internal diameter, is mutually to be intersected and stacked the right cylinder combining by polylith corrugated plate, and corrugated plate is vertically placed, and forms the passage of regular shape between the crest of adjacent corrugated plate and trough.
The utility model is rational in infrastructure, is a kind of new and effective exhaust box, and noise reducing type can improve 40%-60% than old-fashioned exhaust box, and has rainproof function.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation of corrugated plate.
Embodiment
A novel current stabilization noise reducing muffle, comprises housing 3, and the bottom of housing arranges and stretches into the choker-line 1 in housing, and choker-line is set with injection into orbit pipe 2 outward, and the upper end of housing arranges a tubular current stabilization denoising device 4, and rainhat 5 is set above housing; Described current stabilization denoising device directly identical with housing internal diameter, mutually to intersect and stack the right cylinder (crest, the trough that are adjacent corrugated plate are relative) combining by polylith corrugated plate 6, corrugated plate (metal material) is vertically placed, and forms the passage of regular shape between the crest of adjacent corrugated plate and trough.
When air-flow flows out by micropore jet pipe, can between injection into orbit pipe and housing, form high speed endless belt air-flow, above injection into orbit pipe, (being high velocity air endless belt inner side) can form the relative low speed flow of column.When high speed endless belt air flow stream arrives current stabilization denoising device, due to the effect of current stabilization denoising device, its flow direction can change, and a part flows along current stabilization denoising device inner passage, and another part flows to low speed flow, the current stabilization denoising device of then together flowing through.By the special flow body structure of current stabilization denoising device, air-flow becomes low speed air-flow stably, and then greatly reduces the shock wave noise of silencing end.On the other hand, the sound wave of some Low Medium Frequencies of exhaust box inside also can constantly constantly reflect superposition reflective between current stabilization denoising device internal voids, is finally converted into interior energy.Current stabilization denoising device can also prevent that foreign material and flying bird from falling in exhaust box, has guaranteed the safe operation of device.
