Description
Technical field
The utility model belongs to the automobile exhaust dust exhaust, is specifically related to a kind of automotive muffler.
Background technique
When automobile and engineering machinery were worked under dirty environment, the dust in the air filter caused filter core maintenance, replacement cycle to shorten greatly owing to can not in time discharge automatically, increases the user and uses and cost burden.Used the dust discharge of waste gas injection abroad for this reason, it is to arrange throat tubular construction on silencing apparatus tailpipe later, have the induction tunnel interface in its vicinity on the tail pipe, and connecting pipeline is to one-way valve, again through one-way valve, be connected to the dust exhaust port of air filter by pipeline, finish discharge gas ejection dust emission device.The trunnion place, because the abrupt change of cross-section, waste gas be through can forming negative pressure at this later, and the dust at dust exhaust port place is drawn onto the trunnion place by the road, discharged by waste gas again, finishes automatic dust discharge.This kind structure since trunnion and injection interface arrangement on tailpipe, cause the line arrangement complexity, this moment is because tailpipe is long, on vehicle, take bigger space, trend can't be unified, and stability, reliability is bad, again since domestic car load vent systems for the consideration of cost and layout, the tailpipe of design is shorter mostly, and scheme is not suitable for domestic layout outside the native land.And still do not have under the shorter situation of tailpipe, how to solve the problem of utilizing the injection dust discharge at present.
Summary of the invention
So the purpose of this utility model solves the problem of utilizing the injection dust discharge, the silencing apparatus that a kind of discharge gas ejection dust emission device is provided and contains the waste gas injection at shorter at existing tailpipe under the little situation of vehicle arrangement space.
The technological scheme of silencing apparatus of the present utility model is: it comprises suppressor case, noise elimination member in the suppressor case, establish suction tude and steam outlet pipe on the suppressor case, steam outlet pipe is provided with trunnion, and the described trunnion portion induction tunnel interior with stretching into suppressor case communicates.
Described induction tunnel is positioned at suppressor case inside in the go side mutually with trunnion, and the other end passes suppressor case and is positioned at the suppressor case outside.Be that trunnion is located at and is connected UNICOM with the steam outlet pipe of silencing apparatus in the suppressor case.
Described trunnion is connected with suppressor case, constitutes the part of steam outlet pipe or is exactly steam outlet pipe; The connection of one of scheme trunnion is located at suppressor case wall inboard, and steam outlet pipe is located at the suppressor case wall outside, and trunnion communicates with steam outlet pipe; The two trunnions connection of scheme is located at the suppressor case wall outside, and steam outlet pipe is located at suppressor case wall inboard, and trunnion communicates with steam outlet pipe; Three of scheme is that trunnion is connected inside and outside the suppressor case wall, constitutes outlet pipe, is outlet pipe, this moment the trunnion part of gas injection dust exhaust of promptly cancelling, again as the outlet pipe of silencing apparatus.
One end or the intermediate section of described steam outlet pipe have throat tubular construction, and are positioned at suppressor case inside.
One end or the intermediate section of described steam outlet pipe communicate and are fixed with one with trunnion, are positioned at suppressor case inside.
The technological scheme that realizes discharge gas ejection dust emission device of the present utility model is: comprise silencing apparatus, air filter, induction tunnel and connecting pipeline, described induction tunnel passes suppressor case and communicates with the muffler tail pipe trunnion.
The utility model is creationary forms overall structure with silencing apparatus and induction tunnel, and the inner space that makes full use of silencing apparatus is arranged, realizes the injection dust discharge forming a kind of new silencing apparatus product under short tailpipe situation.And the silencing apparatus of new discharge gas ejection dust emission device and new structure is simple in structure, and tailpipe is short, need not to fix in addition, arranges that cost is low easily, and it is little to take the car load space, the reliability height; Can realize the suction tude of induction tunnel, trunnion and silencing apparatus and be arrangeding in parallel of steam outlet pipe.Because tailpipe is shorter, and promptly exhaust outlet helps producing bigger negative pressure, dust discharge is effective automatically in addition.
