Abstract
The utility model discloses a direct wall flow formula porcelain filter who combines together with intersection hole sealing, including the porcelain filter main part, the porcelain filter main part has the through -hole that runs through its main part, the through -hole that is located on the coplanar includes hole sealing portion through -hole and direct portion through -hole. The both ends one end hole sealing of hole sealing portion through -hole and the other end is direct, direct portion through -hole both ends are all direct. Hole sealing portion through -hole, the adjacent hole sealing of two through -holes of same terminal surface and another be the hole sealing not. Direct portion through -hole account for on the coplanar direct portion's through -hole and hole sealing portion through -hole the total 5%-20%. Adopt the utility model discloses a design, it is poor to have overcome china's oil, adopts whole alternately hole sealing modes easily to lead to the problem of blockking up, has improved wall flow formula porcelain filter's life, satisfies 5 standards in the diesel engine exhaust emissions europe simultaneously at least.
Description
Technical field
The utility model relates to a kind of porcelain filter, particularly a kind of straight-through and intersect the wall-flow ceramic filter that sealing of hole combines.
Background technique
The industrialized development of automobile industry, the tail gas pollution brought is also day by day serious.Along with the control criterion of motor vehicle exhaust emission is more and more stricter, during countries in the world comprise, the exhaust emissions of diesel-oil vehicle is also become tight day by day.
Simultaneously, due to the oil product problem of China, sulphur content is higher, and effulent has more soot particulate, the porcelain filter of the employing intersection plug-hole mode that can reach Europe 6, Europe 5 standard if directly adopt, directly can cause the problem that duct blocks, back pressure raises after service time is permanent.
Summary of the invention
Goal of the invention: the purpose of this utility model is that solving the existing porcelain filter of intersection plug-hole mode that adopts is not suitable for China's oil product, can cause the problem that duct blocks, back pressure raises after service time is permanent.
Technological scheme: the utility model provides following technological scheme: a kind of straight-through and intersect the wall-flow ceramic filter that sealing of hole combines, comprise porcelain filter, described porcelain filter has the through hole running through its main body, described through hole comprises sealing of hole portion through hole and straight-through portion through hole, one end, two ends sealing of hole of described sealing of hole portion through hole and the other end leads directly to, through hole two ends, described straight-through portion are all straight-through, and described straight-through portion through hole accounts for 5% ~ 20% of the summation of straight-through portion's through hole and sealing of hole portion through hole on same plane.
As optimization, described straight-through portion through hole is uniformly distributed between sealing of hole portion through hole.
As optimization, sealing of hole portion through hole in the same plane, adjacent two sealing of hole portion through holes sealing of hole and another not sealing of hole.
As optimization, described ceramic filter bodies is cylindrical, and through hole, from its one end rounded face, runs through the rounded face of main body to the other end.
As optimization, described through hole cross section is square.
Beneficial effect: the utility model is relative to prior art: adopt design of the present utility model, overcome China's oil product poor, all intersection sealing of hole modes are adopted easily to cause the problem blocked, improve the working life of wall-flow ceramic filter, be uniformly distributed between sealing of hole portion through hole by straight-through portion through hole, and straight-through portion through hole accounts for 5% ~ 20% of the summation of straight-through portion's through hole and sealing of hole portion through hole on same plane, motor vehicle exhaust emission can be made to meet Europe 5 standard conditions and can not cause duct blocking, back pressure rising for a long time lower service time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to various equivalents of the present invention has all fallen within the application's claims limited range.
Embodiment
As shown in Figure 1, a kind of straight-through and intersect the wall-flow ceramic filter that sealing of hole combines, comprise porcelain filter, described porcelain filter has the through hole running through its main body 3, described through hole comprises sealing of hole portion through hole 1 and straight-through portion through hole 2, one end, two ends sealing of hole of described sealing of hole portion the through hole 1 and the other end leads directly to, through hole 2 two ends, described straight-through portion are all straight-through, and described straight-through portion through hole 2 accounts for 5% ~ 20% of the summation of straight-through portion through hole 2 and sealing of hole portion through hole 1 on same plane.
Described straight-through portion through hole 2 is uniformly distributed between sealing of hole portion through hole 1.
Sealing of hole portion through hole 1 in the same plane, adjacent two sealing of hole portion through holes, 1 one sealing of holes and another not sealing of hole.
Described ceramic filter bodies 3 is cylindrical, and through hole, from its one end rounded face, runs through the rounded face of main body to the other end.Described through hole cross section is square.
Adopt the technological scheme that the present embodiment provides, straight-through portion through hole 2 accounts for 5% ~ 20% of the summation of straight-through portion through hole 2 and sealing of hole portion through hole 1 on same plane.Then, other sealing of hole portion through hole 1 accountings are 80 ~ 95%, and straight-through portion through hole 2 inwall still can have catalyzer, then its filtering effect final is at more than 80 ~ 95% of cross seal cellular type porcelain filter, meet Europe 5 standard, simultaneously can be more smooth and easy due to gas discharging, the particulate matter part of generation is discharged by straight-through portion through hole 2, and working life is more permanent.
Claims (5)
1. the wall-flow ceramic filter leading directly to and intersect sealing of hole and combine, comprise porcelain filter, described porcelain filter has the through hole running through its main body, it is characterized in that: described through hole comprises sealing of hole portion through hole and straight-through portion through hole, one end, two ends sealing of hole of described sealing of hole portion through hole and the other end leads directly to, through hole two ends, described straight-through portion are all straight-through, and described straight-through portion through hole accounts for 5% ~ 20% of the summation of straight-through portion's through hole and sealing of hole portion through hole on same plane.
