Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, embodiment of the present utility model is described further:
From accompanying drawing 1, this utility model is specifically related to a kind of engine exhaust gas purification acoustic filter, mainly include sleeve pipe 1,
Metal bellows 2, air inlet jack pipe 3, lumen orifice pipe 5, purify the purification silencing functional part such as matrix 9, vent well pipe 11 and
Inlet chamber housing 4, discharge chamber housing 10, sieve plate 6, asbestos washer 7, lining 8, sleeve 12 etc. support accessory.
Exhaust purging muffler main body is formed by connecting by flange and bolt by inlet chamber housing 4 and discharge chamber housing 10,
Pad with asbestos washer 7 between the flange of inlet chamber housing 4 and discharge chamber housing 10.Set in the inlet chamber surrounded by inlet chamber housing 4
Have along certain circumferential directions have more than 2 circular holes sieve plate 6 and with circular hole close-connected lumen orifice pipe 5 on sieve plate 6.By arranging
Multiple pie being made up of foamed ceramics is had to purify matrix 9 and for fixing purification matrix in the discharge chamber that air cavity housing 10 surrounds
The lining 8 of 9 and sleeve 12.
The inlet chamber housing 4 surrounding inlet chamber is having for installing air inlet jack pipe 3 on the side of its blind end
Circular hole, air inlet jack pipe 3 one end by circular hole be inserted into air cavity and with inlet chamber housing 4 compact siro spinning technology, air inlet jack pipe 3 is inserted
The end face and the side opening that enter inlet chamber part are porose, and the other end is for carrying externally threaded siphunculus.
The discharge chamber housing 10 surrounding discharge chamber has for installing vent well pipe at the end face center away from inlet chamber
The circular hole of 11, in vent well pipe 11 inserts discharge chamber by circular hole and with discharge chamber housing 10 compact siro spinning technology, vent well pipe
Hole is had on 11 end faces inserting discharge chamber part and side.
Discharge chamber housing 10 has for positioning the protrusion circle purifying matrix 9 on the internal face of vent well pipe 11 side
Ring, the common pie purification matrix 9 being made up polylith of foamed ceramics positions this annulus with the lining 8 of L-shaped.Near aerofluxus
First piece of purification matrix 9 its right end face of jack pipe 11 props up the left end face of prominent annulus on vent well pipe 10.Near entering
