Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Embodiment 1: like Fig. 1, Fig. 2 and shown in Figure 3, a kind of blowdown exhaust silencer comprises housing 9, and the rear and front end of housing 9 is connected with suction tude 1 and outlet pipe 3 respectively, and the internal diameter of outlet pipe 3 equates.The upper reaches with air-flow are that front end, downstream are the rear end, and the front end of housing 9 is provided with front cover 4, and the rear end is provided with rear end cover 5.
The upper reaches of outlet pipe 3 are connected with drain pipe 11, and drain pipe 11 comprises reducing pipe 11a, trunnion 11b and increaser 11c from front to back successively.Be provided with the blowdown tubule 10 that can be connected with air-strainer in the drain pipe 11, the outlet of blowdown tubule 10 is positioned at trunnion 11b place.The front portion of drain pipe 11 is connected with the ingress pipe 19 of uniform internal diameter.
Be arranged at intervals with first dividing plate 6, second partition 7 and the 3rd dividing plate 8 in the housing 9.First dividing plate 6, second partition 7 and the 3rd dividing plate 8 are divided into first chamber 13, second chamber 14, the 3rd chamber 15 and the 4th chamber 16 successively with the inner chamber of housing 9, and the volume of these four chambers each is unequal, to eliminate the noise of different frequency.
Suction tude 1 inserts in first chamber 13 from the front portion of first chamber 13.Second chamber 14 is communicated with through intervalve 2 with first chamber 13.Suction tude 1 and intervalve 2 are the structure of front opening, tail end sealing, and pipe shaft is provided with pore 12.Second chamber 14 is communicated with through short tube 18 with the 3rd chamber 15, and ingress pipe 19 is communicated with the 3rd chamber 15.
In other embodiments, second chamber 14 also can be communicated with through the aperture on the second partition 7 with the 3rd chamber 15, to reach essentially identical technique effect.
Be provided with sound-absorbing material 17 in the 4th chamber 16.
During silencing apparatus work, suction tude 1 is linked to each other with motor, blowdown tubule 10 links to each other with air-strainer.Therefore the high temperature of engine emission, at a high speed, the waste gas of high pulsation gets in first chamber 13 from suction tude 1.Since the front opening of suction tude 1, the tail end sealing, so air-flow can only be from 12 ejections of the pore on the suction tude 1, and the air motion direction changes 90 °, and air-flow is become some shallow bids from a big share reform, and therefore, the engine air flow noise is tentatively reduced.After air-flow gets into first chamber; After overexpansion, deceleration, buffering and voltage stabilizing; Get in second chamber 14 of silencing apparatus through intervalve 2, after overexpansion, deceleration, buffering and voltage stabilizing, get into the 3rd chamber 15 equally through short tube 18; Get in the ingress pipe 19 from the 3rd chamber 15 then, get into drain pipe 11 at last and discharge silencing apparatus from outlet pipe 3.
After air-flow got into reducing pipe 11a, the flow section of air-flow was more and more littler, and the speed of air-flow is increasing with generation degree of vacuum, reached maximum to trunnion 11b place.Because the outlet of blowdown tubule 10 is positioned at trunnion 11b place, therefore under action of pressure, the interior laying dust of air-strainer will be by sucking-off, and with the flowing in the increaser 11c of air-flow, after outlet pipe 3 enter in the atmosphere.
Because during engine exhaust process trunnion 11b, airspeed is very high, will produce regenerated noise, therefore sound-absorbing material 17 is set in the 4th chamber, to eliminate middle and high frequency regenerated noise.
On the other hand; Because each is unequal for the volume of first chamber 13, second chamber 14 and the 3rd chamber 15; The reflection of sound wave in each chamber subdued also inequality, so the degree of air-flow expansion in each chamber, deceleration, buffering and voltage stabilizing also has nothing in common with each other, and therefore can eliminate the noise of different frequency; The air-flow of pulsation at a high speed is adjusted into more stable low speed flow, gets into atmosphere at last.
Embodiment 2: as shown in Figure 4, the structure of present embodiment and embodiment 1 are basic identical, and different is that suction tude 1 inserts from the side of first chamber 13 in the present embodiment.
Other structures of present embodiment are identical with embodiment 1 with working principle.
Embodiment 3: as shown in Figure 5, the structure of present embodiment and embodiment 1 are basic identical, and different is that in the present embodiment, circumference uniform distribution is provided with four short tubes 18 on the second partition 7, to be communicated with second chamber 14 and the 3rd chamber 15.
More than describe the preferred embodiment of the utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technician in the art according to the design of the utility model on the basis of existing technology through the available technological scheme of logical analysis, reasoning, or a limited experiment, all should be in determined protection domain by claims.
