Description
Technical field
The present invention relates to diesel engine arts, especially a kind of diesel engine silencer with soot particles collecting function.
Background technique
Existing silencer has a single function, and can only weaken the noise of exhaust process generation, trapping to soot particles or disappears
Except helpless.The purification techniques of diesel soot particle mostly uses greatly wall flow particulate trap（DPF）It is filtered, with
The gradually accumulation of the particle filtered down will cause DPF blocking, increase engine exhaust back pressure, under dynamic property and economy
Drop, therefore, it is necessary to remove the soot particles assembled in DPF in time, this process is known as regenerating.Although DPF is to soot particles
It traps that effect is fine, but the regeneration of this device is extremely difficult, the methods of electric heating or injection fuel is needed to allow soot particles
It burns.It not only makes the material tolerance of DPF as a result, and service life is difficult to reach requirement, also make entire after-treatment device
Structure is complicated, expensive.
Due to the defect of DPF, much diesel vehicle there is no an after-treatment device of tail gas, exhaust gas passes through straight after silencer
Run in into atmosphere, so, soot particles are all sticked inside silencer, when automobile Hong throttle, these soot particles will be with
Air-flow goes out exhaust pipe together, causes the serious pollution of atmosphere.Only regular dismounting and silencer is cleaned, this over-emitting black exhaust shows
As can just make moderate progress, but the method for this frequent disassembly, cleaning silencer is difficult to be adopted by user.
Summary of the invention
The present invention proposes a kind of diesel engine silencer with soot particles collecting function, and machinery can be integrated on silencer
Formula cleans cleaner to clean exhaust gas from diesel vehicle.
The present invention uses following technical scheme.
A kind of diesel engine silencer with soot particles collecting function, including muffler body, before the silencer
The baffle that can be pushed by exhaust gas is equipped in hush tube, the baffle is equipped with backwards to the end face of preceding hush tube air inlet perpendicular to this
The mobile bar of end face is cased with baffle return springs in the mobile bar, and mobile bar beginning is connected with plate washer, when baffle is by exhaust gas
Baffle compresses baffle return springs when promotion；The baffle peripheral region is equipped with the interior brush with preceding noise elimination inside pipe wall sliding contact；
The mobile bar end connects with brush holder, and the end of the brush holder is fixed with the outer brush with rear noise elimination pipe outer wall sliding contact；When
When the exhaust gas that baffle is entered from preceding hush tube air inlet pushes, brush is slided in preceding noise elimination inside pipe wall and is cleaned in barrier driving, gear
Plate pushes mobile bar to slide outer brush in rear noise elimination pipe outer wall and cleans；When current hush tube air inlet stops air inlet, baffle resets
The movement of hush tube air inlet is resetted to drive interior brush, outer brush to carry out cleaning work again resilient element urges baffle forward.
The silencer is horizontally disposed, and soot particles storage device is equipped with below the preceding hush tube of silencer and rear hush tube and is used
The soot particles got off are cleaned and shaken off from silencer internal wall in brush, outer brush in storage.
The soot particles inlet on soot particles storage device top is equipped with the cover plate that plate suqare is less than entrance, disappears
The sealing plate that sound device both ends are equipped with to support seat supports, the cover plate are supportted with the support shaft of clearance fit in the support of sealing plate
On seat, when current hush tube, rear hush tube generate vibration in noise elimination operation, cover plate synchronous vibrating is the soot in cover plate
Particle shakes off into soot particles storage device.
The soot particles storage device is placed under the preceding hush tube of silencer and rear hush tube with extractable drawer structure cunning
Side.
The silencer is axial symmetry reactive muffler.
The baffle return springs are the spring being placed in mobile bar.
The interior brush, outer brush are high temperatur pot brush.
The baffle that can be pushed by exhaust gas is equipped in the present invention, in the preceding hush tube of the silencer, when in the past baffle is disappeared
When the exhaust gas that sound pipe air inlet enters pushes, brush is slided in preceding noise elimination inside pipe wall and is cleaned in barrier driving, and baffle pushes mobile bar
Outer brush is slided in rear noise elimination pipe outer wall to clean；When current hush tube air inlet stops air inlet, baffle return springs push gear
The movement of hush tube air inlet is resetted to drive interior brush, outer brush to carry out cleaning work again plate forward；The design is soot particles
Clearing apparatus is integrated in inside silencer, is driven using the exhaust gas of discharge to it, neither the noise elimination effect of influence silencer,
Reduce the discharge of soot particles again.Keep exhaust gas processing device small in size, at low cost, structure is simple, energy conservation and environmental protection, is diesel engine
Eliminate the cheap and practical method of soot particles.
In the present invention, the silencer is horizontally disposed, and soot particles are equipped with below the preceding hush tube of silencer and rear hush tube
Storage device is used to store interior brush, outer brush cleans and shake off from silencer internal wall the soot particles got off；The soot
The soot particles inlet on particulate storage device top is equipped with the cover plate that plate suqare is less than entrance, and silencer both ends are equipped with branch
Support the sealing plate of seat supports, the cover plate with the support of the support shaft of clearance fit on the support base of sealing plate, current hush tube,
When hush tube generates vibration in noise elimination operation afterwards, cover plate synchronous vibrating shakes off the soot particles in cover plate micro- into soot
Grain storage device；The design enables is got off and shakes off from silencer internal wall the safe storage of soot particles got off by cleaning,
Environment is avoided pollution, the cover plate on soot particles storage device can stablize the air-flow on soot particles storage device top, prevent
The soot particles fallen into storage room roll out pollution environment by air-flow, and when silencer work, on soot particles storage device
The synchronous concussion of cover plate, it is ensured that the micro- material of soot under cleaning will not lodge in cover plate, so that cover plate will not influence charcoal
The normal storage work of cigarette particulate storage device.
In the present invention, the soot particles storage device is with the sliding preceding hush tube of silencer that is placed in of extractable drawer structure with after
Below hush tube；This is designed as dismountable design, and microcosmic due to soot particles is in cotton-shaped form, and particle can be inhaled at work
It is attached on wall surface, particle also can be adsorbed mutually with particle and be grown up, and the present apparatus, which sweeps the method scraped using machinery, allows it to fall and receive
Collection stores, wait be collected into it is a certain amount of after open drawer cleaning fall ash, do not need entire silencer and disassemble cleaning,
Regenerated problem is also avoided simultaneously.
