Technical field
The utility model relates to air pre-filtering technical field, is specifically related to can be applicable to the air pre-filtrating equipment of being convenient to ash discharge in the engine aspirating system.
Background technique
Motor is the heart of vehicle, and gas handling system then is the artery of motor, and the performance of gas handling system directly influences performance, the life-span of motor, thereby influences machine performance, life-span and the feature of environmental protection.The function of gas handling system is to provide cleaning, drying, sufficient air for motor, therefore, air-strainer need be installed usually in suction tude the place ahead of gas handling system, impurity such as dust, sand grains in the air-strainer filtering air, guarantee to enter in the cylinder air of capacity, cleaning, prevent the wearing and tearing of motor.
In order to alleviate the burden of air-strainer; improve the filtering effect of air inlet and the working life of air-strainer; the air pre-filtrating equipment also can be arranged usually in upstream at air-strainer; the impurity that is used for the coarse filtration air inlet; the general structure of air pre-filtrating equipment comprises housing and is contained in the interior outlet pipe of housing; the ash-discharge opening of lower housing portion and the Ash valves that links to each other with ash-discharge opening; air inlet is through the double filtration of pre-filtrating equipment and air-strainer; enter motor at last; then be deposited in the ash-discharge opening place of air pre-filtrating equipment lower housing portion by the dust of its larger particles of separating through the air pre-filtrating equipment; and finally discharge via Ash valves; so; air-filtering effect and water-proof performance have been improved; improve the air inlet environment of motor, and then prolonged the working life of motor.Yet; air pre-filtrating equipment of the prior art; its ash-discharge opening is generally single straight-tube shape structure; when the air inlet that has the larger particles dust by pre-filtrating equipment separate, when falling to the ash-discharge opening place of slab construction; not having effective external force effect impels impurity such as dust to fall into Ash valves smoothly and be discharged from; therefore be easy to make dust accretion at the ash-discharge opening place, cause the obstruction of pre-filtering passage and finally have influence on pre-filtering efficient, even can cause prefilter to lose efficacy.
The model utility content
The applicant improves at above-mentioned shortcoming of the prior art, and a kind of air pre-filtrating equipment is provided, and it can effectively discharge impurity such as the isolated dust of air pre-filtrating equipment, and has reduced to take up space.
The technical solution of the utility model is as follows:
The air pre-filtrating equipment comprises housing, and it has suction port and air outlet, and lower part of frame has ash-discharge opening, and Ash valves is connected with ash-discharge opening, and lower part of frame is provided with at least two ash-discharge openings, and the upper end section area of ash-discharge opening is greater than its lower end section area.
Its further technological scheme is:
Described ash-discharge opening is inverted trapezoidal shape structure, and the slanted angle of ash-discharge opening two adjacent surfaces and housing bottom horizontal plane is respectively α, β, and wherein at least one angle is more than or equal to 5 °.
Described ash-discharge opening is inverted cone-shaped structure, and the inclined angle alpha of ash-discharge opening and housing bottom horizontal plane is more than or equal to 5 °.
Technique effect of the present utility model:
The utility model adopts the ash-discharge opening structure of inverted trapezoidal shape or inverted cone-shaped structure, can effectively utilize gravity, will be collected in the Ash valves through the impurity such as dust that pre-filtering is separated, and then discharges prefilter; Adopt two and two above inverted trapezoidal shapes or inverted cone ash-discharge opening, can make the overall structure of pre-filtrating equipment more compact, reduce the volume of pre-filtrating equipment effectively, under the situation that the angle angle of ash-discharge opening and housing bottom horizontal plane remains unchanged, can save at least 1/4 arrangement space, reduce to take up space; The angle of ash-discharge opening and housing bottom surface is made as more than or equal to 5 °, and the utility model can be realized good ash discharge effect.

Fig. 2 is the side view of Fig. 1.
Fig. 3 is the assembling stereogram of the utility model and air-strainer.
Wherein: 1, housing; 2, suction port; 3, air outlet; 4, ash-discharge opening; 5, Ash valves; 6, air-strainer.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
See Fig. 1, Fig. 2, the utility model comprises housing 1, and it has suction port 2 and air outlet 3, the bottom of housing 1 has ash-discharge opening 4, Ash valves 5 is connected with ash-discharge opening 4, and the bottom of housing 1 is provided with at least two ash-discharge openings 4, and the upper end section area of ash-discharge opening 4 is greater than its lower end section area.
See Fig. 1, Fig. 2, further, one of embodiment of the present utility model: ash-discharge opening 4 is inverted trapezoidal shape structure, and the slanted angle on ash-discharge opening 4 two adjacent surfaces and housing 1 bottom water plane is respectively α, β, and wherein at least one angle is more than or equal to 5 °.
See Fig. 1, another embodiment of the present utility model: ash-discharge opening 4 is inverted cone-shaped structure, and the inclined angle alpha on ash-discharge opening 4 and housing 1 bottom water plane is more than or equal to 5 °.
Running of the present utility model is as follows:
When reality is used; see Fig. 3; the utility model is contained in before the air-strainer in the vehicle intake system; the motor of work makes in the housing 1 of the present utility model and produces negative pressure; air inlet enters housing 1 from suction port 2; filtration through housing 1 inner filtration assembly; impurity such as the large particle dust in the air inlet are separated; described filter assemblies adopts cyclone tube filter assemblies of the prior art; blade-carrying rotation separation assembly; filter cylinder dedusting assembly etc.; after continuing under the effect in negative pressure to filter again via air-strainer 6, the air after the pre-filtering enters motor; the dust impurity of being separated by the utility model then falls to ash-discharge opening 4 places; because ash-discharge opening 4 adopts inverted trapezoidal shape or inverted cone-shaped structure; be easy to through the larger particles dust that pre-filtering is separated that the plane of inclination from ash-discharge opening 6 tumbles automatically to Ash valves 5 under the effect at gravity; when the dust accretion in the Ash valves 5 arrives to a certain degree; when the self gravitation that namely enters dust in the Ash valves 5 is enough to overcome negative pressure in the housing 1; Ash valves 5 is opened automatically, thereby the impurity of separating such as dust are discharged.
Angle α, the β on the two adjacent surfaces of the ash-discharge opening 4 of inverted trapezoidal shape structure and housing 1 bottom water plane, the angle of the two is more big, and the ash discharge effect is more good, particularly, described angle α, β, when wherein at least one angle was more than or equal to 5 °, the utility model can be realized good ash discharge effect; On the other hand; because the air pre-filtrating equipment can be subjected to spatial constraints usually on car load is arranged; for traditional single straight-tube shape ash-discharge opening; the utility model adopts the ash-discharge opening structure of two or more inverted trapezoidal shapes or inverted cone-shaped structure; can make the overall structure of pre-filtrating equipment more compact; and under the situation that the angle angle on ash-discharge opening 4 and housing 1 bottom water plane remains unchanged, can save at least 1/4 arrangement space, reduce to take up space.
More than describing is to explanation of the present utility model, is not the restriction to model utility, and the utility model institute restricted portion within protection domain of the present utility model, can be done any type of modification referring to claim.
