Abstract
The utility model discloses a vortex inflatable gas storage silencer; a silencingpot is arranged at the upper end and/or the lower end of an gas storage room; the two sides of the radical lines inside the gas storage room are provided with more than one vortex tube; the gas inlet port end of the vortex tube is communicated with the exhaust tube of an engine; the first gas outlet of the vortex tube is communicated with the gas storage room; and the second gas outlet of the vortex tube is communicated with the silencingpot. The vortex inflatable gas storage silencer can lead the waste gas exhausted by the engine to rotate in the gas storage room; the rotating waste gases can not be exhausted into the silencingpot unless the exhaust valve of the engine is closed, which reduces the exhaust resistance of a waste gas flow on the engine, reduces the noise and can be broadly applied to engines of automobiles or motorcars.
Description
Technical field
The utility model relates to a kind of silencing apparatus, relates in particular to a kind of eddy current gas-filled type gas storage noise deadener that is applied on automobile or the motorcycle engine.
Background technique
The structural type that is used for the exhaust silencer on the motor has absorption exhaust silencer, the interfere type exhaust silencer, expanssion type exhaust air separator and resonant exhaust silencer etc., these exhaust silencers are generally by resonant chamber, the pipe of expansion chamber and one group of porous constitutes, its working principle is by repeatedly changing airflow direction air-flow to be repeated by shrinking, expansion constantly is subjected to reflection and disperses, effects such as retardance and throttling, in silencing apparatus, expand, the cooling consumed energy, stream pressure is reduced, vibration weakening, the pneumatic noise that enters atmosphere reduces, and has eliminated flame and the Mars in the exhaust flow simultaneously again.In order further to reduce the noise of motor, also adopted secondary or three grades of silencing apparatuss, but the anti-engine exhaust back pressure that makes of excessive sound deadening capacity raises, the power loss of motor is increased.
Summary of the invention
The purpose of this utility model is to provide a kind of eddy current gas-filled type gas storage noise deadener that can further reduce waste gas noise, reduce the engine exhaust resistance.
For achieving the above object, the technical solution adopted in the utility model is: eddy current gas-filled type gas storage noise deadener described in the utility model includes silencing pot, gas storage chamber, vortex tube and outlet pipe.Make a gas storage chamber with metallic material, be connected with silencing pot in the upper end and/or the lower end of gas storage chamber, by contrast, the existing known silencing pot expansion chamber volume of the expansion chamber volume ratio of described silencing pot is little.Radial line both sides in gas storage chamber are provided with N (integer of N 〉=1) layer (individual) vortex tube, and the suction port of vortex tube communicates with waste pipe, and first air outlet of vortex tube is communicated with gas storage chamber, and second air outlet of vortex tube is communicated with silencing pot.
Adopt a kind of eddy current gas-filled type gas storage noise deadener that as above technological scheme provides compared with prior art, technical characteristics is:
The waste gas that motor is discharged does not directly enter gas storage chamber, but be introduced into each layer vortex tube by outlet pipe, vortex tube forces a part of waste gas to rotate in gas storage chamber, because the inertia of air-flow, make the exhaust flow in the gas storage chamber after engine exhaust port is closed, enter silencing pot, reduced the instantaneous flow of waste gas in silencing pot, reduced the exhaust resistance of waste gas, reduced noise motor.
Description of drawings
Fig. 1 is the forward cross-sectional schematic of a kind of eddy current gas-filled type gas storage noise deadener described in the utility model, also is Figure of abstract of the present utility model.
Fig. 2 is that A-A along Fig. 1 is to cross-sectional schematic.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described in detail.
A kind of eddy current gas-filled type gas storage noise deadener described in the utility model is the integrated type gas storage noise deadener, it comprises silencing pot 1, gas storage chamber 2, vortex tube 3 and outlet pipe 4, wherein silencing pot 1 is a known systems, identical with common air separator with motor, vortex tube 3 is forced vortex inflation vortex tube.In the top and bottom of gas storage chamber 2 tube 1 of cooling down can be installed simultaneously, also can silencing pot 1 be installed respectively in the upper end or the lower end of gas storage chamber 2.Be provided with quantity in the radial line both sides of gas storage chamber 2 inner chambers more than or equal to 1 vortex tube 3, this set pattern can be selected symmetric type or asymmetric.The suction port 31 of vortex tube 3 communicates with waste pipe 4, and the waste gas that motor is discharged can enter suction port 31 through outlet pipe 4.Vortex tube 3 forms slit aperture because of 3 of N layer vortex tubes that are provided with, so vortex tube 3 is the forced aeration vortex tube, each layer vortex tube 3 forms first air outlet 32 and second air outlet 33.First air outlet 32 of vortex tube 3 is communicated with gas storage chamber 2, and second air outlet 33 of vortex tube 3 is communicated with silencing pot.By on the eddy current gas-filled type gas storage noise deadener formed also can be referred to as exhaust processor.
According to the installation or the use condition of described eddy current gas-filled type gas storage noise deadener, can offer drain opening 5 in the bottom of gas storage chamber 2 or not offer drain opening 5.
When engine exhaust, begin to be the supercritical exhaust stage, the engine air in-cylinder pressure is higher, and the waste gas flow velocity is fast.The waste gas of discharging when motor is when outlet pipe 4 enters vortex tube 3, because effect of inertia, the part of exhaust flow is come out to be full of gas storage chamber 2 (as Fig. 2) with rotation mode by first air outlet 32 of vortex tube 3, another part of exhaust flow flows to second air outlet 33 of vortex tube 3 through first air outlet 32 of vortex tube 3 subsequently, enters silencing pot 1 through second air outlet 33 of vortex tube 3 again.Because waste gas is made swirling motion in gas storage chamber 2, increase eddy current, increase gas-storing capacity, make the center pressure in the gas storage chamber 2 low, when the pressure in the engine exhaust pipe 4 descended, the air-flow in the gas storage chamber 2 also can not return out immediately, and the air-flow in gas storage chamber 2 stops the rotation; Air-flow in gas storage chamber 2 is done interbody spacer section in the opposite direction rotation, and exhaust flow enters before the silencing pot 1 exhaust valve of motor by second air outlet 33 of vortex tube 3 and closes.As seen, that part of air-flow that enters gas storage chamber 2 squeezes mutually with the air-flow that does not enter gas storage chamber 2, and the engine exhaust resistance is reduced, and has reduced noise, realizes purpose described in the utility model.
