Description
(1) technical field
The present invention relates to a kind of ship exhaust pipe, more particularly to the reverse-filling exhaust pipe for preventing inwelling.
(2) background technology
When traveling or reversing, the exhaust pipe of ship pours in down a chimney ship by seawater or river sometimes, after water inlet
It is easy to cause flame-out.It is just out of question if can start after flame-out；If after flame-out cannot start, need to tear machine maintenance open.Thus
As it can be seen that after the exhaust water inlet tube of ship, it is possible to engine is caused to damage, adds ship maintenance cost.Therefore it is badly in need of grinding
Send it is a kind of can prevent the exhaust pipe preventing return water device of ship, and then ensure the stability that ship uses
(3) content of the invention
In order to overcome the shortcoming of spot ship exhaust pipe, the present invention provides a kind of reverse-filling exhaust pipe.
The technical proposal of the invention is realized in this way：
A kind of reverse-filling exhaust pipe of this programme, including exhaust pipe main body, the output terminal of the exhaust pipe main body are provided with
Surge chamber；The surge chamber is laterally disposed cylindrical structural；It is described buffering chamber cross-section area from middle part to both sides by
It is decrescence small；The output terminal of the surge chamber is connected with anti-down flow tube；The anti-down flow tube closes the pipe of other end opening for one end
Shape structure；One section of the anti-down flow tube is extend into inside surge chamber；The pipe of the anti-down flow tube extending into inside surge chamber
Mouth closing；Some through holes are provided with the tube wall of the anti-down flow tube for stretching into surge chamber；Anti-down flow tube outside the surge chamber
Be internally provided with some partitions；The partition is to be obliquely installed；The inclined direction of partition is the direction of flue gas output；Institute
The length for stating partition is less than the half of anti-backflow bore；The output terminal of the anti-down flow tube is additionally provided with air guide port；It is described to lead
Gas port is flexibly connected with anti-down flow tube.
Further, in the surge chamber partition plate is additionally provided between anti-down flow tube and exhaust pipe main body.
The invention has the beneficial effects that：It is simple in structure, it is easy to use, while preventing seawater or river water from pouring in down a chimney also
The noise of exhaust outlet can be reduced.
(4) illustrate
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is the sectional view of surge chamber.
Wherein：1- exhaust pipe main bodys, 2- surge chambers, the anti-down flow tubes of 3-, 4- through holes, 5- partitions, 6- air guide ports, 7- partition plates.
(5) embodiment
Brief description is made to one embodiment of the present invention below in conjunction with the accompanying drawings.
Such as a kind of reverse-filling exhaust pipe of Fig. 1 and Fig. 2, including exhaust pipe main body 1, the output terminal of the exhaust pipe main body 1
It is provided with surge chamber 2；The surge chamber 2 is laterally disposed cylindrical structural；The area of 2 cross section of surge chamber is by middle part
It is gradually reduced to both sides；The output terminal of the surge chamber 2 is connected with anti-down flow tube 3；The anti-down flow tube 3 is closed another for one end
Hold open tubular structure；One section of the anti-down flow tube 3 is extend into inside surge chamber 2；It is described to extend into inside surge chamber 2
The mouth of pipe closing of anti-down flow tube 3；Some through holes 4 are provided with the tube wall of the anti-down flow tube 3 for stretching into surge chamber 2；It is described slow
That rushes the anti-down flow tube 3 in the outside of room 2 is internally provided with some partitions 5；The partition 5 is to be obliquely installed；The 5 inclined side of partition
To the direction exported for flue gas；The length of the partition 5 is less than the half of anti-down 3 internal diameter of flow tube；The output of the anti-down flow tube 3
End is additionally provided with air guide port 6；The air guide port 6 is flexibly connected with anti-down flow tube 3；Anti-down flow tube 3 and exhaust in the surge chamber 2
Partition plate 7 is additionally provided between pipe main body 1.
The course of work of this example：The flue gas that ship produces is entered in surge chamber 2 by exhaust pipe main body 1, due to slow
Rush room 2 to be internally connected with there is provided the anti-down flow tube 3 of some through holes 4, flue gas enters anti-down flow tube 3 by through hole 4, due to through hole
4 effect, can effectively reduce the noise of engine flue gas generation, and the partition 5 of anti-down 3 tilted setting of flow tube also plays
The effect of noise reduction, flue gas are discharged finally by air guide port 6, can be according to the traveling of ship since the direction of air guide port 6 adjusts
Environment carrys out adjusting position, reduces the risk poured in down a chimney, and secondly, the partition 5 being obliquely installed can also play the work that barrier seawater enters
With if having seawater entrance accidentally, the structure of surge chamber 2 can also retain a part of seawater, reduce further seawater and pass through
Exhaust pipe main body 1 enters the probability of engine, and the setting of partition plate 7 can also prevent water in surge chamber 2 in case of turbulence
Into engine.
One embodiment of the present of invention is described in detail above, but the content is only the preferable implementation of the present invention
Example, it is impossible to be construed as limiting the practical range of the present invention.All all the changes and improvements made according to the present patent application scope
Deng, should all still belong to the present invention patent covering scope within.
