Abstract
The utility model discloses a flame arrester applicable to a motor vehicle exhaust pipe. The flame arrester applicable to the motor vehicle exhaust pipe comprises a fire retardance cylinder, a guide pipe and a spark receiving tank, wherein one end of the fire retardance cylinder is fixedly connected with the motor vehicle exhaust pipe; a grid plate is arranged inside the other end of the fire retardance cylinder; the spark receiving tank is filled with water for extinguishing sparks; the guide pipe is a conical tube; the large-caliber end of the guide pipe is communicated with the fire retardance cylinder; the small-caliber end of the guide pipe is communicated with the spark receiving tank; and the diameter of the large-caliber end of the guide pipe is 4 times of that of the small-caliber end of the guide pipe. The probability for the sparks to enter the spark receiving tank is increased, so that the fire retardance cylinder can effectively prevent the sparks from being exhausted along with exhaust gas and thus the driving safety of a motor vehicle in a chemical plant is improved.
Description
Technical field
The utility model safety installation technical field, relates in particular to a kind of flame trap that is applicable to motor vehicle exhaust.
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 cylinder 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, have certain speed, and the bore of conduit is less, causes Mars can not drop exactly in Mars receiving tank due to Mars, Mars is still easily followed flue gas and is discharged, and back-fire relief effect is bad.
Model utility content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, a kind of flame trap that is applicable to motor vehicle exhaust is provided, the utility model has improved the probability that Mars enters Mars receiving tank, can effectively stop Mars to follow flue gas and discharge, improve 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 flame trap that is applicable to motor vehicle exhaust, it is characterized in that: comprise back-fire relief cylinder, conduit and Mars receiving tank, one end of described back-fire relief cylinder is fixedly connected with motor vehicle exhaust, in the other end, be provided with screen, the in-built water that extinguishes Mars that is useful on of described Mars receiving tank, described conduit is conical pipe, its heavy caliber end is communicated with back-fire relief cylinder, small-caliber end is communicated with Mars receiving tank, and the heavy caliber end diameter of described conduit is 4 times of small-caliber end diameter.
The diameter of described conduit successively decreases successively in 10% ratio.
The tank body of described Mars receiving tank is cone structure, and its small-caliber end is threaded with the small-caliber end of conduit.
Employing the utility model has the advantage of:
One, in the utility model, conduit adopts conical pipe, and its heavy caliber end is communicated with back-fire relief cylinder, and Mars can be dropped exactly in Mars receiving tank, can effectively stop Mars to follow flue gas and discharge, improve the Security that Motor Vehicle travels at chemical plant on-site; Owing to having vibration in motor-driven vehicle going process, therefore the small-caliber end of conduit is communicated with Mars receiving tank again, can prevent that the water in Mars receiving tank from overflowing and pouring in down a chimney to outlet pipe in motor-driven vehicle going process, is conducive to improve Security.
Two, in the utility model, the diameter of described conduit successively decreases successively in 10% ratio, and this structure makes Mars along the successfully landing of the tube wall of conduit to Mars receiving tank, can avoid Mars to splash.
Three, in the utility model, the tank body of described Mars receiving tank is cone structure, and its small-caliber end is threaded with the small-caliber end of conduit, and this structure can further prevent that the water in Mars receiving tank from overflowing, and is conducive to improve the driving safety of Motor Vehicle.
Brief description of the drawings
Fig. 1 is structural representation of the present 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, screen.
Embodiment
A kind of flame trap that is applicable to motor vehicle exhaust, comprise back-fire relief cylinder 1, conduit 2 and Mars receiving tank 3, one end of described back-fire relief cylinder 1 is fixedly connected with motor vehicle exhaust, in the other end, be provided with screen 6, the in-built water that extinguishes Mars that is useful on of described Mars receiving tank 3, described conduit 2 is set to conical pipe, the diameter of conduit 2 successively decreases successively in 10% ratio, the heavy caliber end of described conduit 2 is communicated with back-fire relief cylinder 1, small-caliber end is communicated with Mars receiving tank 3, and the heavy caliber end diameter of described conduit 2 is 4 times of small-caliber end diameter, Mars can be dropped in Mars receiving tank 3 by conduit 2 exactly, be conducive to put forward back-fire relief effect.
In the utility model, the inlet end 4 of described back-fire relief cylinder 1 is connected with motor vehicle exhaust, and described screen 6 is arranged in the outlet side 5 of back-fire relief cylinder 1.
In the utility model, the tank body of described Mars receiving tank 3 is preferably set to cone structure, and its small-caliber end is threaded with the small-caliber end of conduit 2, can either in Mars receiving tank 3, overflow by anti-sealing, is convenient to again change safeguard Mars receiving tank 3.
