Abstract
The utility model relates to a split multifunction silencer, and the utility model belongs to the class of the accessories of vehicles. The utility model is composed of a cylinder, a gas feeding connection pipe welded at the front of the cylinder body, and a gas exhausting connection pipe welded at the back end of the cylinder body. A front partition plate, a middle partition plate whose upper part is provided with a notch, and a back partition plate whose lower part is provided with a notch are respectively arranged in the cylinder from the front to the back; a gas feeding bending pipe is welded backwards at the upper part of the front partition plate, and the back end of the gas feeding bending pipe is welded on a transverse front silencing plate which is evenly provided with holes; the upper part of the back partition plate is welded with a one-way valve, and a transverse back silencing plate which is evenly provided with holes is welded between the back partition plate and the middle part of the back end face of the cylinder body; the wall of the cylinder body is welded with a water filling pipe and a plug, the tail of the vehicles has circuitous flow in the cylinder body, and the tail gas is purified and absorbed twice by purified water; the utility model has the advantages of silencing and purifying.
Description
The utility model belongs to Motor Vehicle annex baffler class.
Motor Vehicle is for noise reduction and alleviate pollution to atmosphere, at the outlet pipe afterbody baffler is housed all.Present baffler has is added with thermal reaction apparatus and catalysis device in the cylindrical shell of baffler, purpose is to make harmful gases such as carbon monoxide in the tail gas of vehicular emission, hydrocarbon, sulfur dioxide carry out thermal response and catalytic reaction, to alleviate the pollution to air.But above-mentioned baffler cost is somewhat expensive, is difficult to apply.
The purpose of this utility model is: the separate type multifunctional baffler that a kind of low-cost, purifying effect and good muffling effect are provided.
Technical measures of the present utility model are: based on the baffler of being made up of the vent connection of the air inlet tube of cylindrical shell, barrel front end seam, cylinder back-end seam; In cylindrical shell from front to back successively seam preceding dividing plate, top central diaphragm jaggy, bottom rear bulkhead jaggy are arranged; Intake elbow is arranged at preceding dividing plate top seam backward, and the rear end seam of intake elbow is on horizontal uniform porose preceding acoustical panel; In the seam of rear bulkhead top an one-way valve is arranged; Middle part seam at rear bulkhead and cylinder back-end face has horizontal uniform porose back acoustical panel; Seam has filler pipe on the barrel wall between preceding dividing plate and central diaphragm, central diaphragm and rear bulkhead.The blowdown plug is arranged on the diapire of cylindrical shell.
-for fuel-economizing, inflammable gas is reclaimed, burn away; In the seam of barrel front end face the recovery tube that leads between central diaphragm and the rear bulkhead is arranged, recovery tube front end and air-strainer join.
Baffler of the present utility model has good muffling effect, good effect that the tail gas clean-up degree is high.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an outline drawing of the present utility model.
Drawing explanation and embodiment are described below.2 is cylindrical shells among the figure, and cylindrical shell 2 front end seam have air inlet tube 1, and cylindrical shell 2 rear end seam have vent connection 12; In cylindrical shell 2 from front to back successively seam preceding dividing plate 4, top central diaphragm 8 jaggy, bottom rear bulkhead 10 jaggy are arranged; Intake elbow 5 is arranged at preceding dividing plate 4 tops seam backward, and the rear end seam of intake elbow 5 is on horizontal uniform porose preceding acoustical panel 7; In the seam of the top of rear bulkhead 10 one-way valve 11 is arranged; Middle part seam at rear bulkhead 10 middle parts and cylindrical shell 2 ear end faces has horizontal uniform porose back acoustical panel 13; Seam has filler pipe 6 and 9 on the wall of the cylindrical shell 2 of 10 of preceding dividing plate 4 and central diaphragm 8, central diaphragm 8 and rear bulkheads; Blowdown plug 14 and 15 are arranged on the diapire of cylindrical shell 2.For fuel-economizing, reclaim the lighter inflammable gas of proportion, a recovery tube 3 that leads between central diaphragm 8 and the rear bulkhead 10 can be arranged in the front-end face seam of cylindrical shell 2, recovery tube 3 front ends and air-strainer join, inflammable gas is reclaimed burn away, baffler of the present utility model is owing to adopt preceding acoustical panel 7 and back acoustical panel 13, carry out twice noise reduction, the characteristics of good muffling effect are arranged.Since between the aft bulkhead of preceding dividing plate 4 and central diaphragm 8, central diaphragm 8 and cylindrical shell 2, be equipped with and purify waste water, the tail gas that Motor Vehicle is discharged, and circuitous flowing through the adsorption cleaning of purifying waste water twice, has the high characteristics of purification ratio to harmful gas in cylindrical shell 2.The profile of this baffler is identical with the baffler of Motor Vehicle such as existing C A141, CA142, EQ140, SY1041, and just internal structure is improved, can make things convenient for like this with existing above-mentioned Motor Vehicle by dress.
