Owing to the reasonable selection of various parameters, the utility model has the advantages of simple structure and low cost. The utility model has no effect on each performance indicator of the engine besides the obvious effect of extinguishing and a certain effects of sound attenuation and smoke abatement, easy to organise the large-scale production.
Description
A kind of automobile-used arc arrester, it belongs to the device of engine exhaust system.
In the prior art, the effective arc arrester of engine exhaust mainly contains following several types: a) maze type arc arrester; B) water-bath type arc arrester; C) grid-plate type arc arrester; D) laminated type arc arrester; E) combined arc arrester.
The maze type arc arrester can only stop red-hot particle, and can not stop propagation of flame effectively, and because air-flow is repeatedly turned or collided, drag losses is big, the rate of fuel consumption height; The flame-out effect of water-bath type arc arrester is better, but complex structure, exhaust resistance is bigger, needs to use resistant material, and cost is higher; Grid-plate type and laminated type arc arrester are comparatively effective for stoping gas flame, but stop effect relatively poor for red-hot solid particle, and need with heat-resisting corrosion resistant plate manufacturing, the machining accuracy height, cost is expensive, and combined arc arrester is to unite use by two kinds of above-mentioned arc arresters, and effect is good certainly, but complex structure, the cost height.
In a word, the various arc arresters of present domestic use, though certain flame-out ability is arranged, drag losses is big, the rate of fuel consumption height, structure more complicated, and the stainless steel materials manufacturing of the current shortage of need use, cost is expensive, applies to be restricted.
The purpose of this utility model is, designs a kind of automobile-used arc arrester, is installed on the outlet pipe of automobile and tractor engine, makes them can be in the reservoir area, Inflammable factory, and travel safely in places such as harbour.This automobile-used arc arrester should be simple and reasonable, and volume is suitable, and drag losses is little, and rate of fuel consumption is low, low price, and have certain noise elimination effect and be convenient to promote the use of.
Formation of the present utility model is, a kind of automobile-used arc arrester, and it comprises a suction tude, a preceding capping, a shell, 3～4 dividing plates, a rear seal-cover and an outlet pipe.On the preceding capping of shell and the rear seal-cover suction tude and outlet pipe are housed respectively, 3～4 dividing plate dislocation are fixed on the inner chamber of shell.Divergence ratio m=(the D of this arc arrester
2)/(d
2)=3.5～4.5, in the formula, D is a housing diameter, d is the suction tude diameter; Area ratio of combustion chamber passage n=(A)/(Ao)=1.2～1.6, in the formula, A is the air-flow path area of arc arrester internal partition, A
0Be the suction tude sectional area; Slenderness ratio λ=(L)/(D)=1.6～2.4, in the formula, D is a housing diameter, and L is an outer cover length.Between the dividing plate and dividing plate of above-mentioned arc arrester, dividing plate equates with spacing between the rear seal-cover.The spherical radius R=100 of dividing plate～140 millimeter, punching rate P=20 on the dividing plate～30% becomes equilateral triangle to arrange between the Kong Yukong, row's datum hole heart line-spacing dividing plate shaft axis apart from a=(S)/4, S is the length of side that the hole constitutes equilateral triangle, and circle lacks size A 〉=1/2 (D+d
1) in the formula, D is a housing diameter, d
1Be the outlet pipe diameter.
Description of drawings
Accompanying drawing 1 is the structural drawing of an automobile-used arc arrester.
Accompanying drawing 2 is structural drawing that shell is connected with preceding capping.
Accompanying drawing 3 is dividing plate figure.
Be an embodiment of the present utility model below, provide details of the present utility model by description and accompanying drawing to this embodiment.
Fig. 1 is the structural drawing of an automobile-used arc arrester.The length overall of this arc arrester is 410 millimeters, diameter of the housing D=120 millimeter.It comprises a suction tude (1), a preceding capping (2), a shell (3), 3 dividing plates (4), a rear seal-cover (5), an outlet pipe (6).After the steel plate roll extrusion of above-mentioned suction tude (1), shell (3) and outlet pipe (6), be welded into cylindrical shape with δ=1 millimeter; Before capping (2) and rear seal-cover (5) also use the steel plate drawing of δ=1 millimeter.The length of suction tude (1) is 85 millimeters, inner diameter d is divided into the groove that 61 millimeters, 58 millimeters and 54.5 millimeters third gear, ends have four 35 millimeters long, so as successfully to be sleeved on liberation, east wind and the outlet pipe of the board motor car engine of making a leapleap forward on, the other end stretches into the endoporus of preceding capping (2) and welds together.Equally, the length of outlet pipe (6) is 125 millimeters, outside diameter d
1=62 millimeters, the angle that an end-grain cutting is at 45, the other end inserts the endoporus of rear seal-cover (5) and welds together.The length of shell (3) is 218 millimeters, outer diameter D=120 millimeter, dividing plate (4) dislocation spot welding is at the inner chamber of shell (3), and guarantee between dividing plate and the dividing plate, the distance between dividing plate and the rear seal-cover all is 50 millimeters.
Accompanying drawing 2 is shells and the structural drawing that is connected of preceding capping, and this structure also is applicable to being connected of shell and rear seal-cover, and among the figure, the crimping (2a) of preceding capping (2), (2b) surround the crimping (3a) of shell (3), and be engaged after compressing.This structure makes the edge of shell (3) have enough rigidity, and sealing is good.
Accompanying drawing 3 is dividing plate figure, dividing plate (4) strikes out circle with the steel plate of δ=1.2 millimeter and lacks sphere shape, spherical radius R=120 millimeter, circle lacks size A=95 millimeter, be covered with 241 apertures on the sphere, its diameter is 3.2 millimeters, and triangularity is arranged between the Kong Yukong, the length of side S=6.2 millimeter of this equilateral triangle.One row's datum hole heart line (8) apart from shaft axis (9) apart from the a=1.5 millimeter, this dividing plate (4) that makes three same sizes is after dislocation is arranged, its eyelet does not overlap at axial direction.
The divergence ratio m=4 of above-mentioned automobile-used arc arrester, area ratio of combustion chamber passage n=1.4, slenderness ratio λ=1.8, punching rate P=25%, it adheres to specification evidence fully.
