Abstract
The utility model discloses a safe fire barrier for a motor vehicle. The safe fire barrier comprises a fire blocking cylinder, a guide tube and a spark containing tank. The fire blocking cylinder comprises an air inlet end and an air outlet end, wherein the air inlet end is fixed on an exhaust pipe of the motor vehicle. The guide tube is respectively communicated with the fire blocking cylinder and the spark containing tank. Two filtering plates are obliquely, symmetrically and fixedly arranged in the fire blocking cylinder, provided with through holes and located between the guide tube and the air outlet end of the fire blocking cylinder. According to the safe fire barrier for the motor vehicle, the moving speed of sparks can be reduced, the sparks are completely prevented from being discharged along with smoke, and the safety performance of driving the motor vehicle within a chemical plant is improved.
Description
Technical field
The utility model belongs to safety installation technical field, relates in particular to a kind of safe flame trap for Motor Vehicle, and this flame trap is mainly used in the Motor Vehicle travelling at the chemical plant on-site that No Open Flames.
Background technique
At present, the motor vehicle flame arrester of known technology be mainly that the smoke and fire star that vehicle exhaust exhaust pipe is discharged passes through an extension tube with screen, but this design is very unreasonable, Mars is still easily followed flue gas and is discharged through screen, does not play the object that stops Mars to drop on the ground.
In order to address the above problem, following patented technology is proposed in prior art:
As China Patent No. " 201020524186.8 " discloses a kind of motor vehicle flame arrester, its open day is on 04 27th, 2011, its technological scheme is described flame trap, by upper lasso, upper wire rope, back-fire relief cylinder, screen, conduit, Mars receiving tank, lower lasso, lower wire rope composition, on back-fire relief stack shell, leave conduit, conduit connects Mars receiving tank, in Mars receiving tank, be filled with water, the back-fire relief cylinder left side is uncovered, the screen in circular hole hole is left on back-fire relief cylinder the right, wire rope is left on nozzle top, the back-fire relief cylinder left side, upper wire rope connects upper lasso, lower wire rope is left in nozzle bottom, the back-fire relief cylinder left side, lower wire rope connects lower lasso.But in actual use, while following flue gas discharge due to Mars, have certain speed, this just causes only having the Mars of close Mars receiving tank easily to drop in Mars receiving tank, discharge and still easily follow flue gas away from the Mars of Mars receiving tank, back-fire relief effect is bad.
Model utility content
The purpose of this utility model is to solve the above-mentioned problems in the prior art, a kind of safe flame trap for Motor Vehicle is provided, the utility model can reduce the movement velocity of Mars, stops Mars to follow flue gas completely and discharges, and has improved the Security that Motor Vehicle travels at chemical plant on-site.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of safe flame trap for Motor Vehicle, it is characterized in that: comprise back-fire relief cylinder, conduit and Mars receiving tank, described back-fire relief cylinder comprises inlet end and outlet side, described inlet end is fixed on motor vehicle exhaust, described conduit is communicated with back-fire relief cylinder and Mars receiving tank respectively, and described back-fire relief cylinder is tilted is provided with two filter plates, on described filter plate, is provided with through hole, described two filter plate symmetries are fixed in back-fire relief cylinder, and two filter plates are between conduit and the outlet side of back-fire relief cylinder.
Described back-fire relief cylinder is conically shaped, and its small-caliber end is inlet end, and heavy caliber end is outlet side.
On described back-fire relief cylinder, be also connected with Mars receiving tank, this Mars receiving tank is between two filter plates.
Employing the utility model has the advantage of:
One, in the utility model, can reduce the movement velocity of Mars by two filter plates, the filter plate of two inclinations can effectively prevent that Mars is discharged to outside back-fire relief cylinder, thereby increase the probability that Mars drops in Mars receiving tank, reach the object that stops Mars to be discharged completely, improved the Security that Motor Vehicle travels at chemical plant on-site.
Two, in the utility model, back-fire relief cylinder is set to conically shaped, the volume of back-fire relief cylinder increases gradually from inlet end to outlet side, make first filter plate to the pressure between inlet end be greater than the pressure between first filter plate and second filter plate, can reduce gradually the movement velocity of flue gas, even if part Mars by first filter plate, also can be stopped by second filter plate, effectively improve back-fire relief effect.
Three, in the utility model, on described back-fire relief cylinder, be also connected with Mars receiving tank, this Mars receiving tank is between two filter plates, and this structure can be collected by the Mars of first filter plate, further improves back-fire relief effect.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of filter plate in the utility model.
In figure, be labeled as: 1, back-fire relief cylinder, 2, conduit, 3, Mars receiving tank, 4, inlet end, 5, outlet side, 6, filter plate, 7, through hole.

In the utility model, the through hole 7 on described filter plate 6 is multiple, is evenly distributed on filter plate 6 by ring-type.
In the utility model, described back-fire relief cylinder 1 is preferably set to conically shaped, its small-caliber end is inlet end 4, heavy caliber end is outlet side 5, back-fire relief cylinder 1 is connected with motor vehicle exhaust by small-caliber end, correspondingly, the diameter difference of two filter plates 6, is greater than filter plate 6 diameters near conduit 2 near filter plate 6 diameters of outlet side 5.
In the utility model, preferably on described back-fire relief cylinder 1, connect again a Mars receiving tank 3, and this Mars receiving tank 3 is arranged between two filter plates 6, can collect like this by the Mars of first filter plate 6, further improve back-fire relief effect.
In the utility model, pack a certain amount of water in Mars receiving tank 3 into, rapidly the Mars in Mars receiving tank 3 is extinguished guaranteeing,, change for the ease of the maintenance of Mars receiving tank 3 meanwhile, Mars receiving tank 3 is preferably threaded with conduit 2.
