The diesel engine muffler is characterized in that a baffle capable of being pushed by waste gas is arranged in a front muffler tube of the diesel engine muffler; a moving rod vertical to the end surface is arranged on the end surface, back on to a gas inlet of the front muffler tube, of the baffle; a baffle reset elastic piece is arranged on the moving rod in a sleeving manner; the initial end of the moving rod is connected with the baffle; the baffle compresses the baffle reset elastic piece when being pushed by the waste gas; an inner brush in contact with the inner wall of the front muffler tube is arranged on the periphery of the baffle; the tail end of the moving rod is connected with a brush frame, and an outer brush in contact with the outer wall of a rear muffler tube is fixed at the end part of the brush frame; when being pushed by the waste gas entering from the gas inlet of the front muffler tube, the baffle drives the inner brush to clean the inner wall of the front muffler tube; the baffle pushes the moving rod, so that the outer brush cleans the outer wall of the rear muffler tube; when gas stops entering the gas inlet, the baffle reset elastic piece pushes the baffle to move and reset towards the gas inlet of the front muffler tube so as to drive the inner brush and the outer brush to clean again; mechanical cleaning and dust removing equipment can be integrated on the muffler to clean tail gas from a diesel engine.
Description
Technical field
The present invention relates to diesel engine arts, especially a kind of diesel engine silencer with soot particles collecting function.
Background technology
The single function of existing acoustic filter, can only weaken the noise of exhaust process generation, the trapping to soot particles or disappear
Except at a loss what to do.The purification techniques of diesel soot microgranule adopts wall flow particulate catcher mostly（DPF）Filtered, with
The gradually accumulation of the microgranule filtering down, can cause DPF to block, and so that engine exhaust back pressure is increased, under dynamic property and economy
Fall, therefore, it is necessary to remove the soot particles assembled in DPF in time, this process is referred to as regenerating.Although DPF is to soot particles
Very well, but the regeneration of this device is extremely difficult for trapping effect, needs the methods such as electrical heating or spray fuel to allow soot particles
Burn.Thus, not only make the material toleration of DPF and service life difficult to reach requires, also make whole after-treatment device
Complex structure, cost intensive.
Due to the defect of DPF, much diesel vehicle there is no the after-treatment device of tail gas, waste gas is straight after acoustic filter
Run in into air, so, all stick soot particles inside acoustic filter, when automobile Hong throttle, these soot particles will be with
Air-flow goes out exhaustor together, causes the severe contamination of air.Only regular dismounting clean acoustic filter, the showing of this over-emitting black exhaust
As just making moderate progress, but the method for this frequent disassembly, cleaning acoustic filter is difficult to be adopted by user.
Content of the invention
The present invention propose a kind of diesel engine silencer with soot particles collecting function, can on acoustic filter integrated machinery
Formula cleans cleaner to clean exhaust gas from diesel vehicle.
The present invention employs the following technical solutions.
A kind of diesel engine silencer with soot particles collecting function, including muffler body, before described acoustic filter

Plate promotes mobile bar so that outer brush is slided in rear noise elimination pipe outer wall and cleans；When current hush tube air inlet stops air inlet, baffle plate resets
Hush tube air inlet moves reset to drive interior brush, outer brush to carry out cleaning work again to resilient element urges baffle plate forward.
Described acoustic filter is horizontally disposed with, and is provided with soot particles storage device and uses below the front hush tube of acoustic filter and rear hush tube
In storage, brush, outer brush clean and shake off, from silencer internal wall, the soot particles got off.
The soot particles porch on described soot particles storage device top is provided with the coverage plate that plate suqare is less than entrance, disappears
Sound device two ends are provided with to support the sealing plate of seat supports, the support shaft that described coverage plate is coordinated with gap support in sealing plate support
On seat, when current hush tube, rear hush tube produce vibrations in noise elimination operation, cover plate synchronous vibrating the soot covered on plate
Microgranule shakes off into soot particles storage device.
Described soot particles storage device is placed under the front hush tube of acoustic filter and rear hush tube with extractable drawer structure cunning
Side.
Described acoustic filter is axial symmetry reactive muffler.
Described baffle plate return springs are the spring being placed in mobile bar.
Described interior brush, outer brush are high temperatur pot brush.
In the present invention, it is provided with the baffle plate that can be promoted by waste gas in the front hush tube of described acoustic filter, when baffle plate is disappeared in the past
When the waste gas that sound pipe air inlet enters promotes, in barrier driving, brush slides in front noise elimination inside pipe wall and cleans, and baffle plate promotes mobile bar
Make outer brush slide in rear noise elimination pipe outer wall to clean；When current hush tube air inlet stops air inlet, baffle plate return springs promote gear
Hush tube air inlet moves reset to drive interior brush, outer brush to carry out cleaning work again to plate forward；This design is soot particles
Clearing apparatus is integrated in inside acoustic filter, using the waste gas discharged, it is driven, neither the noise elimination effect of impact acoustic filter,
Decrease the discharge of soot particles again.Make exhaust gas processing device small volume, low cost, structure is simple, and energy-conserving and environment-protective, are diesel engines
Eliminate the cheap and practical method of soot particles.
In the present invention, described acoustic filter is horizontally disposed with, and is provided with soot particles below the front hush tube of acoustic filter and rear hush tube
Storage device is for storing interior brush, outer brush cleans and shakes off, from silencer internal wall, the soot particles got off；Described soot
The soot particles porch on particulate storage device top is provided with the coverage plate that plate suqare is less than entrance, and acoustic filter two ends are provided with to prop up
The sealing plate of support seat supports, the support shaft that described coverage plate is coordinated with gap support in sealing plate on support base, current hush tube,
When hush tube produces vibrations in noise elimination operation afterwards, coverage plate synchronous vibrating shakes off the soot particles covered on plate micro- into soot
Grain storage device；This design enables to be cleaned and shakes off the safe storage of the soot particles got off from silencer internal wall,
Avoid polluting environment, the coverage plate on soot particles storage device can stablize the air-flow on soot particles storage device top, prevents
The soot particles falling in storage room are rolled out pollution environment by air-flow, and during acoustic filter work, on soot particles storage device
Plate of covering synchronously concussion will not lodge on coverage plate so that coverage plate does not interfere with charcoal it is ensured that cleaning the lower micro- material of soot
The normal storage work of cigarette particulate storage device.
In the present invention, described soot particles storage device with extractable drawer structure cunning be placed in the front hush tube of acoustic filter and after
Below hush tube；This is designed as dismountable design, and because the microcosmic of soot particles is in cotton-shaped form, microgranule can be inhaled at work
