Abstract
The utility model provides an anti-explosion silencing device of a multifunction silencer, which relating to the exhaust system field of vehicle motors. The anti-explosion silencing device of the middle section of the multifunction silencer is provided with an anti-explosion chamber and a silencing chamber. A plurality of identical anti-explosion silencers 7 for simultaneous silencing are arranged in the anti-explosion chamber. The noise frequency of the anti-explosion silencers is the same. Acoustic waves are weakened due to mutual impact. Sparkles in gas are extinguished. Noise and temperature are further decreased because the space of the silencing chamber is enlarged. The noise is 10 db smaller than an international standard through a test. No sparkles are discharged in waste gas. The utility model has the advantages of non-accident initiation and high safety.
Description
The utility model provides a kind of explosion-proof silencer of multifunction silencer of dynamic power machine.The vent systems field that relates to vehicle motor relates to a kind of automobile multifunctional silencing apparatus particularly.
In the prior art, the exhaust silencer of vehicle all is with a circle or oval-shaped shell, and the centre has a circular core pipe to run through front and back, and the intermediate portion of core pipe has been covered with many apertures, in order to eliminate the noise that engine exhaust sends.Because silencing apparatus core pipe diameter dimension is restricted, so erasure effect is not good, decrease of noise functions is low, and explosion-proof effect is poor, and automobile enters oil depot, liquefied gas station, and during flammability zone such as chemical industry warehouse, the waste gas that silencing apparatus is discharged contains Mars, and is easily accidents caused, very dangerous.
The utility model overcomes above-mentioned shortcoming, provides that a kind of erasure effect is good, explosion-proof, the explosion-proof silencer of the futuramic multifunction silencer of low noise.
The scheme that the utility model solves is to set up several explosion-proof baffler 7 noise reductions simultaneously, allows noise cancel out each other, and controls in order to make an uproar that the method for making an uproar realizes.The major technology feature is the stage casing of multifunction silencer, in the circular housing 2, between dividing plate 6 and rear bulkhead 10, is explosion-proof silencer.This device is divided into two sections of front and back with central diaphragm 9 with it.Leading portion has explosion-proof cell, and back segment is the anechoic chamber.Inner casing 8 is a cylindrical shape, and two ends are connected with dividing plate 6, central diaphragm 9 respectively and shell 2 constitutes an explosion-proof cell.Several same explosion-proof baffler 7 is set in it, is distributed on the dividing plate 6 and the emission-control equipment of front communicates.Several circular holes are arranged on the central diaphragm 9, and explosion-proof baffler 7 therefrom passes respectively.Explosion-proof baffler 7 is a tubulose, has been covered with many apertures on it.Between central diaphragm 9 and the rear bulkhead 10, be a bigger space, be the anechoic chamber.The gas of discharging from the front emission-control equipment, during by the explosion-proof baffler 7 of on the dividing plate 6 several, noise generated frequency is identical, sends on several position simultaneously, and noise is cancelled out each other.Mars in the exhaust is extinguished by explosion-proof baffler 7 time, therefore has explosion prevention function, and the gas that explosion-proof baffler 7 is discharged enters the anechoic chamber of central diaphragm 9 back, because space enlargement further reduces noise and temperature.
The utility model has the advantages that: erasure effect is obvious, and delivery temperature is low, and the Mars in the exhaust is extinguished, and explosion-proof performance is good.
Description of drawings:
Fig. 1 is the sectional arrangement drawing of multifunction silencer.
Fig. 2 is the B-B sectional drawing of Fig. 1.
In conjunction with the embodiment who provides among the figure, describe the utility model in detail.
With reference to figure 1, Fig. 2, the utility model is by the shell 2 of multifunction silencer, dividing plate 6, and explosion-proof baffler 7, inner casing 8, central diaphragm 9, rear bulkhead 10 is formed.
The suction port of multifunction silencer is connected with waste pipe.The waste gas that motor is discharged enters multifunction silencer, through emission-control equipment, has just entered six explosion-proof silencing apparatuss 7 on the dividing plate 6.Six explosion-proof bafflers 7 are distributed in the explosion-proof cell of shell 2, inner casing 8, dividing plate 6 and rear bulkhead 9 compositions, and when sending the noise of same frequency simultaneously, its sound wave impacts mutually and weakens, so noise reduces greatly.Mars in the gas by explosion-proof baffler 7 time, is also extinguished.The gas of discharging enters the anechoic chamber behind the central diaphragm 9, because space enlargement, noise and temperature are further reduced, and just enter next device.
After tested: noise is lower than 10 decibels of GBs.No Mars is discharged in the waste gas.
Also can be made into special explosion-proof silencing apparatus as required, be used for special device and special vehicle.This explosion-proof silencer has obvious noise reduction, does not have Mars in the exhaust, can not cause fire and explosive accident, and is safe and reliable, be suitable for widely popularize universal.
