The anti-explosion silencer comprises a silencing barrel and an anti-explosion barrel, wherein the silencing barrel and the anti-explosion barrel are split, a silencing tube of which the wall is provided with alveolate through holes is arranged in the silencing barrel, one end of the silencing barrel is communicated with the cavity of the tip of the silencing barrel, and the other end of the silencing barrel is a sealed end; one end of an inlet pipe, which is connected with the engine, is communicated with the cavity of the tip of the silencing barrel, one end of the big cavity of the silencing barrel and one end of the cavity of the anti-explosion barrel are communicated by a communicating tube, and the other end of the anti-explosion barrel is communicated with an exhaust pipe. The anti-explosion silencer of the utility model has simple structure, easiness in manufacturing, convenience of maintenance, low cost and good anti-explosion damping effect.
Description
Technical field
The utility model relates to the vent systems field of vehicle motor, relates to a kind of explosion-proof silencing apparatus specifically.
Background technique
The explosion-proof silencing apparatus of installing on the motor car engine is to stop sound transmission and extinguish the spark in the waste gas and a kind of device of allowing air communication to cross, is in order to eliminate air power noise, to guarantee the vehicle exhaust Security and the important measures taked.The explosion-proof cell of explosion-proof silencing apparatus of the prior art and anechoic room substantially all are arranged in the pipe of a hollow, and the centre separates by dividing plate, the noise elimination poor effect, and explosion-proof performance is unsatisfactory.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Security and the higher explosion-proof silencing apparatus of stability are provided.
For solving above technical problem, the technical solution of the utility model is:
A kind of explosion-proof silencing apparatus, comprise silencing pot and explosion-proof vent, described silencing pot and explosion-proof vent are the structures of split, and the hush tube that has cellular through hole on the tube wall is housed in the silencing pot, one end of hush tube is communicated with the termination cavity of silencing pot, and the other end of hush tube is a closed end; One end of the suction tude that is connected with motor is communicated with the termination cavity of silencing pot, and the big cavity of silencing pot is communicated with by connecting tube with an end of explosion-proof vent cavity, and the other end of explosion-proof vent cavity is communicated with outlet pipe.
Described silencing pot and explosion-proof vent have same central axis, and the axis of described hush tube and connecting tube all is parallel to the central axis of silencing pot.
The cavity volume of described explosion-proof vent is greater than the cavity volume of silencing pot.
The tail end of described outlet pipe is crooked straight down, and bending radius is more than or equal to 1.5 times of the outlet pipe caliber.
Be at least three described connecting tube.
Described hush tube is more than three.
The beneficial effects of the utility model:
1, divide the silencing pot of body structure and explosion-proof vent manufacturing simple in structure, easy, convenient for maintaining, cost lower.
2, explosion-proof silencing apparatus tail gas of the present utility model enters the bigger explosion-proof cell cavity of volume after by anechoic room, explosion-proof like this noise elimination better effects if, the Mars of failing to extinguish in anechoic room arrives in the explosion-proof cell and can both extinguish substantially, and big cavity more helps eliminating sound.
3, outlet pipe is crooked straight down, and bending radius has guaranteed that more than or equal to 1.5 times of the outlet pipe caliber air-flow in the motor vehicle exhaust emission process is unobstructed.
4, adopt a plurality of connecting tube and hush tube, can better realize gas communication, the noise elimination better effects if.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 is suction tude, and 2 is silencing pot, and 3 is outlet pipe, and 4 is explosion-proof vent, and 5 is hush tube, and 6 is connecting tube, and 7 is cellular through hole, and 8 is the termination cavity.
Embodiment
Embodiment: referring to Fig. 1.A kind of explosion-proof silencing apparatus, comprise silencing pot and explosion-proof vent, described silencing pot 2 and explosion-proof vent 4 are structures of split, and the hush tube 5 that has cellular through hole 7 on the tube wall is housed in the silencing pot 2, one end of hush tube 5 is communicated with the termination cavity 8 of silencing pot 2, and the other end of hush tube 5 is a closed end; One end of the suction tude 1 that is connected with motor is communicated with the termination cavity 8 of silencing pot 2, and the big cavity of silencing pot 2 is communicated with by connecting tube 6 with an end of explosion-proof vent 4 cavitys, and the other end of explosion-proof vent 4 cavitys is communicated with outlet pipe 3.
Described silencing pot 2 and explosion-proof vent 4 total same central axis, described hush tube 5 and the axis of connecting tube 6 all are parallel to the central axis of silencing pot 2.
The cavity volume of described explosion-proof vent 4 is greater than the cavity volume of silencing pot 2.
The tail end of described outlet pipe 3 is crooked straight down, and bending radius is more than or equal to 1.5 times of the outlet pipe caliber.
Described connecting tube 6 is at least three.
Described hush tube 5 is more than three.
Explosion-proof silencing apparatus tail gas of the present utility model enters silencing pot 2 by suction tude 1, owing in the silencing pot 2 hush tube 5 that has cellular through hole 7 is installed, part acoustic energy because and the friction between the cellular through hole 7 consume, when hush tube 5 employing muffler materials were made, sound can be absorbed.Gas by silencing pot 2 back from entering the bigger explosion-proof vent of volume 4 connecting tube 6, big cavity more helps eliminating sound, explosion-proof like this noise elimination better effects if, the Mars of failing to extinguish in anechoic room arrives in the explosion-proof cell and can both extinguish substantially,
The tail end of described outlet pipe 3 is crooked straight down, and bending radius is more than or equal to 1.5 times of the outlet pipe caliber.Can guarantee that like this there is certain distance the air outlet apart from motor vehicle body, when transporting article, guarantee not ignited by the residual gas in the tail gas for explosive material.
Described connecting tube 6 is at least three.
Described hush tube 5 is more than three or three.
Adopt a plurality of connecting tube and hush tube, can better realize gas communication, the noise elimination better effects if.
