Description
Technical field
The utility model relates to a kind of miniature silencer.
Background technique
Diesel engine unit is the core drive that boats and ships are navigated by water, also be the core source of ship power supply, but diesel engine unit is in operation and produces quite high noise, wherein the noise in exhaust emissions process has occupied quite a few, to environment, brought pollution, and severe exacerbation crewman's work living environment, how to reduce diesel engine unit noise in running, be an importance of improvement work and living environment.
Summary of the invention
In order to address the above problem, the utility model provides a kind of miniature silencer, and this device is arranged in exhaust duct of diesel engine, can effectively reduce the noise of diesel engine vent gas in discharge process.
The utility model has adopted following technological scheme: a kind of miniature silencer, it comprises cylindrical shell, in cylindrical shell, be provided with lower separate space plate and upper separate space plate, both are separated into three chambers by cylindrical shell, between lower separate space plate and upper separate space plate, be provided with hush pipe, described hush pipe is comprised of inlet end hush pipe, outlet side hush pipe and transmission hush pipe three, and three is run through respectively lower separate space plate and upper separate space plate, and three's surrounding is equipped with several bloops; The upper end of described cylindrical shell and inlet end hush pipe connectivity part are provided with suction port, and the bottom of cylindrical shell and outlet side hush pipe connectivity part are provided with air outlet; Between the upper head plate of cylindrical shell and lower separate space plate, be provided with arc-shaped partition, between upper separate space plate and the lower end sheet of cylindrical shell, be provided with arc lower dividing plate, described upper arc-shaped partition is separated inlet end hush pipe, transmission hush pipe and outlet side hush pipe, described arc lower dividing plate is separated outlet side hush pipe, transmission hush pipe and inlet end hush pipe, the upper end of described transmission hush pipe is communicated with the upper end of outlet side hush pipe, and the bottom of described transmission hush pipe is communicated with the bottom of inlet end hush pipe.
The neutral position of described cylindrical shell is provided with two mounting base; The outside of described cylindrical shell is coated with heat insulation layer.
The utlity model has following beneficial effect: the utility model can effectively reduce the noise of diesel engine in exhaust emissions process, and stop high-temperature tail gas to airborne propagation heat, fully reached the function of cooling noise reduction; The utility model adopts circuitous configuration, has effectively increased the stroke of air-flow, and noise reduction long flow path has been realized small size, large function.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
