Abstract
The invention discloses a simulated self-draining engine exhaust silencer which comprises a silencer shell, an air inlet perforated pipe, a partition plate, a front end cover, a rear end cover, an air outlet perforated pipe, a metal porous material layer and a metal porous pipe. The air inlet perforated pipe and the air outlet perforated pipe respectively penetrate the silencer shell, the metal porous material layer is welded or riveted on the inner wall of the air outlet perforated pipe, the bottom of the air outlet perforated pipe is perpendicularly connected with the metal porous pipe, the upper end of the metal porous pipe is communicated with the metal porous material layer, and the metal porous pipe contacts with accumulated water at the bottom of the silencer shell. When an engine runs, the accumulated water at the bottom of a cavity of the silencer shell continuously enters the metal porous material layer through the metal porous pipe. The metal porous material layer is wetted by the water, and the water is drained in the form of water molecules or droplets under the exhaust action of the silencer. Rusting, etching and the like of the silencer shell seriously affecting the silencing performance of the silencer due to acid solution can be effectively prevented, and the service life of the silencer is prolonged.
Description
Technical field
The present invention relates to muffler for motor technical field, particularly a kind of principle of copying the moisture transpiration effect on plant leaf blade surface to drive trunk internal flow to realize long distance transportation realizes the bionic engine exhaust silencer from drain function.
Background technique
Silencing apparatus is the important accessory of motor car engine, for reducing the noise of engine exhaust.The waste gas that motor is discharged is mainly water vapour and sour gas after three-way catalytic apparatus purified treatment.Silencing apparatus is in the end of whole vent systems, and the temperature of tail gas is relatively low, easily makes water vapor condensation Cheng Shui, thus forms acid solution with sour gas and lodge in silencing apparatus inside.Silencing apparatus is originally as metal material, and long-term contact with acid solution can corrode silencing apparatus material, makes the acoustic attenuation performance degradation of silencing apparatus, finally causes silencing apparatus to lose efficacy.
The common method solving exhaust silencer ponding problem has two kinds usually, and one is draining of punching on silencing apparatus end cap or housing bottom, and the method can effectively discharge the ponding accumulated in silencing apparatus cavity.But, due to the existence of weep hole, cause vent systems to be leaked gas serious, weaken the Noise Reduction of silencing apparatus, also easily cause the etching problem of silencing apparatus simultaneously, cause silencing apparatus shortening in working life.Another kind method is application siphon principle, and the water bottom silencing apparatus, through exhaust core pipe, is drawn onto in outlet pipe by syphon tube and discharges by air-flow.But the method draining is thorough, and syphon tube position define strict restriction.
Summary of the invention
The object of the present invention is to provide a kind of novel bionical from draining engine exhaust muffler.The moisture transpiration effect that the present invention is based on plant leaf blade surface drives trunk internal flow to realize the principle of long distance transportation, moisture bottom silencing apparatus is drawn by capillary force, under the driving of transpiration by water discharge, thus realize engine exhaust muffler from drain function.Draining of the present invention is thorough, the not strict demand of mounting point.
The present invention is by suppressor case, suction port perforated pipe, dividing plate, front cover, rear end cover, air outlet perforated pipe, metal polyporous material layer and metal perforated pipe composition, suction port perforated pipe and air outlet perforated pipe are located in suppressor case inside respectively, suction port perforated pipe and air outlet perforated pipe are by the membrane support being positioned at suppressor case inside, the front end and back end of suppressor case is closed by front cover and rear end cover respectively, the front end of suction port perforated pipe is stretched out from front cover, the afterbody of air outlet perforated pipe stretches out from rear end cover, the inwall welding of air outlet perforated pipe or riveted joint metal polyporous material layer, the bottom vertical connection metal perforated tube of air outlet perforated pipe, the upper end of metal perforated pipe is communicated with metal polyporous material layer, the lower end of metal perforated pipe is positioned at the bottom of suppressor case inside, metal perforated pipe contacts with water bottom suppressor case.
The thickness of described metal polyporous material layer is 3mm.
Described metal polyporous material layer is through-hole structure, and metal polyporous material layer has moisture absorption.
Working principle of the present invention is:
During engine running, due to the effect of transpiration and capillary force, the ponding of suppressor case cavity bottom constantly enters metal polyporous material layer by metal perforated pipe.Metal polyporous material layer soaks by water, and under the effect of silencing apparatus exhaust, water is discharged with water molecule or with the form of droplet.
Beneficial effect of the present invention:
Invention introduces the moisture transpiration effect imitating plant leaf blade (the metal polyporous material layer referring to welding in the present invention or be riveted on the perforated pipe of air outlet) surface and drive the transport of trunk (being equivalent in the present invention be welded on the metal perforated pipe on the perforated pipe of air outlet) internal flow, thus realize the self-draining function of silencing apparatus, moisture can be realized technically and enter outlet pipe more fast, thus discharge with high temperature gas flow, avoid perforate on silencing apparatus end cap or housing simultaneously, effectively can prevent the suppressor case corrosion caused because of acid solution, the phenomenon that eating thrown etc. have a strong impact on Sound Elimination Performance of Mufflers occurs, extend the working life of silencing apparatus.
