Abstract

The invention discloses an automobile exhaust filtering device which comprises a shell. An air inlet pipe is installed at the left end of the shell. An end cover is arranged at the right end of the shell. A connecting pipe is integrally formed on the left side face of the end cover. A thread is formed on the surface of the connecting pipe. The connecting pipe is connected with the right end of the inner surface of the shell through the thread. First convex lugs are evenly distributed at the right end of the outer surface of the shell. Second convex lugs matched with the first convex lugs are arranged on the end cover. The first convex lugs and the second convex lugs are connected through bolts. An exhaust pipe is installed in the middle of the right side face of the end cover. According to the automobile exhaust filtering device, first diffluence holes in a first partition plate and second diffluence holes in a second partition plate are matched so that gas entering the shell can be subjected to diffluence, and the flowing stroke of exhaust gas inside the shell is increased; due to the fact that the first diffluence holes are formed around the first partition plate at equal intervals, exhaust diffluence is uniform, and the filtering effect is improved.

Preferably, described shell is cylindrical structural.
Preferably, the quantity of described second lug is four, and four the second lugs are equidistant to be circumferentially positioned on end cap.
Preferably, described second partition is positioned at the middle part of shell, and two the first dividing plates are symmetrical arranged about second partition.
Compared with prior art, the invention has the beneficial effects as follows: this automobile tail gas filtering device, the gas entering in shell can be shunted by the cooperation utilizing the first tap hole on the first dividing plate and the second tap hole on second partition, increase tail gas flowing stroke in the enclosure, it is circumferentially positioned on the first dividing plate owing to the first tap hole is equidistant, so that the shunting of tail gas is the most uniform, improve filter effect, end cap can take off activated carbon granule after being used for a while that fill enclosure be replaced, change more convenient, due to without shell is replaced, therefore saved cost.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present invention;
Fig. 2 is right side of the present invention structural representation;
Fig. 3 is the present invention the first diaphragm structure schematic diagram;
Fig. 4 is second partition structural representation of the present invention.
In figure: 1 shell, 2 air inlet pipe, 3 first tap holes, 4 first dividing plates, 5 second partitions, 6 second tap holes, 7 first lugs, 8 second lugs, 9 connecting tubes, 10 filter screens, 11 exhaustors, 12 end caps.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
nullRefer to Fig. 1-4,The present invention provides a kind of technical scheme: a kind of automobile tail gas filtering device,Including shell 1,Shell 1 is cylindrical structural,The inner chamber active charcoal granule of shell 1,The left end of shell 1 is provided with air inlet pipe 2,The right-hand member of shell 1 is provided with end cap 12,The left surface of end cap 12 is integrally formed with connecting tube 9,The surface of connecting tube 9 offers screw thread,The setting of connecting tube 9 not only facilitates the dismounting of end cap 12,And end cap 12 can be made the most firm with the connection of shell 1,This connecting tube 9 is connected with the right-hand member of shell 1 inner surface by screw thread,End cap 12 can take off the activated carbon granule filled internal to shell 1 after being used for a while be replaced,Change more convenient,Due to without shell 1 is replaced,Therefore saved cost,The right-hand member of shell 1 outer surface is evenly distributed with the first lug 7,And it is provided with second lug 8 suitable with the first lug 7 on end cap 12,The quantity of the second lug 8 is four,Four the second lugs 8 are equidistant to be circumferentially positioned on end cap 12,It is bolted between first lug 7 and the second lug 8,First lug 7 and the second lug 8 with the use of,End cap 12 can be fixed on the positioning,There is skew when end cap 12 will not be made to use or drop,Stability is higher,
nullThe middle part of end cap 12 right flank is provided with exhaustor 11,And the right-hand member of exhaustor 11 left end and air inlet pipe 2 is all embedded with filter screen 10,The diameter of filter screen 10 mesh is less than the diameter of activated carbon granule,So that the activated carbon granule in shell 1 inner chamber can be blocked by filter screen 10,Shell 1 be internally provided with second partition 5 and two the first dividing plates 4,And second partition 5 is between two the first dividing plates 4,Second partition 5 is positioned at the middle part of shell 1,And two the first dividing plates 4 are symmetrical arranged about second partition 5,The first first-class distance of dividing plate 4 is surrounded with the first tap hole 3,It is circumferentially positioned on the first dividing plate 4 owing to the first tap hole 3 is equidistant,So that the shunting of tail gas is the most uniform,Improve filter effect,The middle part of second partition 5 offers the second tap hole 6,The aperture of the first tap hole 6 and the second tap hole 6 is four to six times of activated carbon granule,When activated carbon granule is changed by needs,Only end cap 12 need to be taken off,Then the right-hand member making shell 1 is inverted,Rock shell 1,Activated carbon granule old in shell 1 flows out from the right-hand member of shell 1,Then new activated carbon granule is poured in shell 1,Rock shell 1 simultaneously,The activated carbon granule that these are new is made to flow along the first tap hole 3 and the second tap hole 6,And make these new activated carbon granules be filled to the inner chamber of whole shell 1,Then end cap 12 is contained on shell 1 and can use,First tap hole 3、Second tap hole 6、First dividing plate 4、Between second partition 5 with shell 1 inwall coordinate,The curved motion of tail gas entering in shell 1 inner chamber can be made,The gas entered in shell 1 can be shunted by the cooperation utilizing the first tap hole 3 on the first dividing plate 4 and the second tap hole 6 on second partition 5,Increase tail gas flowing stroke in shell 1.
