Detailed description of the invention
In order to enable preferably the technical solution of the utility model to be understood, below by specifically embodiment and combine
Accompanying drawing is described in detail:
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of smoke evacuation Mars of the present utility model extinguishes acoustic filter, including suppressor case
8, inner core 7 and dividing plate 6.
Suppressor case 8 is tubular structure；Dividing plate 6 is arranged on the inside of suppressor case 8, is separated by suppressor case 8
Become inlet plenum 81 and chamber 82 of giving vent to anger；The port of inlet plenum 81 is provided with an air inlet 83, and air inlet is provided with air inlet
Flange；The give vent to anger port of chamber 82 is provided with a gas outlet 84, and gas outlet 84 is provided with flange of giving vent to anger.Acoustic filter passes through air inlet
Flange and exhaustor connect, and Diesel engine expellant gas enters acoustic filter via air inlet 83, passes through after treatment
QI KOU 84 is directly to airborne release, or enters the follow-up tail gas treatment device by Flange joint of giving vent to anger.On gas outlet 84 also
It is provided with a back pressure and measures mouth 2, in order to measure the air pressure of the gas by acoustic filter.
Four through holes are offered on dividing plate 6；It is internal that the pipe shaft of four inner cores 7 is respectively positioned on suppressor case 8, is worn by through hole
Cross dividing plate 6, connect inlet plenum 81 and chamber 82 of giving vent to anger.It is evenly equipped with on the barrel of the stack shell being positioned at inlet plenum 81 of inner core 7
Some passages 71.The port of the stack shell being positioned at chamber 82 of giving vent to anger of inner core 7 connects an elbow 5 of giving vent to anger, each elbow 5 of giving vent to anger
Gas outlet be all right against the sidewall of another elbow 5 of giving vent to anger.
One group of suspension ring ear 3 it is additionally provided with, it is simple to the installation of acoustic filter and fixing on suppressor case 8.
The inlet plenum 81 of suppressor case 8 and the surface of shell of chamber 82 of giving vent to anger are respectively equipped with a sewage draining exit 4.Blowdown
Mouth 4 soot particle in acoustic filter internal washing and acoustic filter is discharged.
The first inlet plenum 81 entering suppressor case 8 through acoustic filter air inlet 83 of Diesel engine expellant gas, one
Portion gas can move to chamber 82 of giving vent to anger through inner core 7, and another part is blocked by dividing plate 6, produces the effect of gas distribution, increases
The stroke of portion gas, thus the gas interior Mars realizing the first step extinguishes.Uniform some passages on inner core 7 tube wall
71, the gas blocked by dividing plate 6 can enter inner core 7 by the hole on tube wall, stops that filtering ash realizes the by loose structure
The Mars of two steps extinguishes.Gas arrives, by inner core 7, chamber 82 of giving vent to anger, and inner core 7 end connects elbow 5 of giving vent to anger, and gas is by curved
5 enter gas outlets 84.By elbow 5 aerofluxus of giving vent to anger, the gas lateral discharge to chamber 82 of giving vent to anger can be made, and and non-immediate court
Discharge to gas outlet 84, make gas fully spread in exhaust chamber, increase the stroke of gas, thus reach the fire of the 3rd step
Star extinguishes.
The function of dissipative muffler and reactive muffler taken into account by this acoustic filter, utilizes the porous sound absorption on inner core 7 inwall
Structure and sound-absorbing material, eliminate the HFS in sound.The multiple cavity of muffler desing can make sound in communication process
There is producing the reflection of acoustic energy, interference, thus reduce by acoustic filter to extraradial low frequency, the acoustic energy of intermediate-frequency section.Thus it is big
The generation of amplitude reducing noise.
A kind of smoke evacuation Mars of the present utility model extinguishes acoustic filter, and the structure that have employed muffler shell socket inner core sets
Meter, the simple in construction manufacturing process difficulty of its each assembly is low, and acoustic filter is quick and easy for installation, thus improves smoke evacuation Mars and put out
Acoustic filter production efficiency of going out and stability in use and reliability, it is to avoid use condition of jolting or other are severe
The environment that uses the use of acoustic filter is impacted, and once there is problem, its simple structure also makes maintenance the most just
Prompt.
This acoustic filter in actual use can also according to the exhaustor quantity of diesel engine and the size of exhaustor, change into
The quantity of QI KOU and size, as changed an air inlet pipe into, it is possible to change the caliber of air inlet and exhaust piper as required.
Those of ordinary skill in the art is it should be appreciated that above embodiment is intended merely to illustrate that this practicality is new
Type, and it is not used as to restriction of the present utility model, as long as in spirit of the present utility model, to the above
The change of embodiment, modification all will fall in Claims scope of the present utility model.
