Abstract
The utility model relates to a device for prolonging the service life of an air filter element of an engine. The device comprises a prefilter dust discharge outlet, a low-temperature pipeline, a one-way valve, a high-temperature pipeline and an exhausting Venturi tube, wherein the prefilter dust discharge outlet is connected with one end of the one-way valve through the high-temperature pipeline, and the other end of the one-way valve is connected with the exhausting Venturi tube through the high-temperature pipeline. The device for prolonging the service life of the air filter element of the engine has the advantages of being high in reliability, simple in structure, convenient to implement, and capable of achieving efficient automatic dust discharging, effectively improving a separation effect on dust and prolonging the service life of the filter element.
Description
Technical field
The utility model relates to a kind of engine air filter core, relates in particular to a kind of device that prolongs the engine air filter element life.
Background technique
The automatic dust discharge mode of present a kind of prefilter of using always, it mainly uses liking road vehicle, as passenger vehicle, truck etc., and some other motor that is operated in the slight dust environment.There are the following problems for this automatic dust discharge mode: 1, dust discharge efficient is low: the dust collection manner inefficiency of the gravity fall of this dependence dust, because falling speed is slow, dust can be sucked in the empty filter of subordinate by air inlet in dropping process greatly, particularly under severe dust environment, often cause the significantly shortening in air filtering core life-span; 2, dust exhaust port is fragile: because the engine charge pulse ratio a little less than, for sensitiveer induction suction pulsation, dust exhaust port generally adopts soft rubber material manufacturing, so this dust discharge valve is damaged, aging easily, the dust exhaust port that damages not only can't dust discharge, also can suck more dusts; 3, dust exhaust port easily stops up: if suck moisture in the air inlet, mix the back with dust and easily stop up dust exhaust port, the dust exhaust port after the obstruction can cause prefilter to lose efficacy.
As previously discussed, when bulldozer uses above-mentioned automatic dust discharge prefilter, it is very high that its operating cost will become, mainly be the working life that has shortened empty filter filter core, make the replacing of filter core frequent, caused bigger waste, improved operating cost, reliability is lower in addition.So, when this automatic prefilter is used for bulldozer, its dust discharge mode improved being very important.
The model utility content
Technical problem to be solved in the utility model is: a kind of device that prolongs the engine air filter element life is provided, can effectively improves the engine charge filtering effect, and prolong the purpose of filter element life.
The utility model is that the technological scheme that the problem of the above-mentioned proposition of solution adopts is:
A kind of device that prolongs the engine air filter element life, comprise prefilter dust exhaust port 1, cryogenic pipe 2, one-way valve 3, high temperature conduit 4 and exhaust Venturi tube 5, prefilter dust exhaust port 1 links to each other with one-way valve 3 one ends by cryogenic pipe 2, and the other end of one-way valve 3 links to each other with exhaust Venturi tube 5 by high temperature conduit 4.
Described one-way valve 3 is the gas control one-way valve.
Described exhaust Venturi tube 5 is stainless steel exhaust Venturi tube.
Working principle of the present utility model: when the exhaust Venturi tube is flowed through in exhaust, produce pressure reduction at the high temperature conduit two ends, the driving air-flow sucks the dust at prefilter dust exhaust port place in the cryogenic pipe, and discharges with waste gas, and one-way valve prevents that the exhaust of heat from blowing back into generation ill-effect in the prefilter.
The beneficial effects of the utility model are: the utility model, and the reliability height, simple in structure, it is convenient to implement, and not only can realize dust discharge automatically efficiently, also will effectively improve its dust separation effect, prolongs filter core working life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is scheme of installation of the present utility model.
Wherein, 1-prefilter dust exhaust port, 2-cryogenic pipe, 3-one-way valve, 4-high temperature conduit, 5-exhaust Venturi tube, 6-air prefilter, the empty filter of 7-, 8-motor, 9-silencing apparatus.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
With reference to Fig. 1-2, the described a kind of device that prolongs the engine air filter element life of this embodiment, comprise prefilter dust exhaust port 1, cryogenic pipe 2, one-way valve 3, high temperature conduit 4, exhaust Venturi tube 5, air prefilter 6, empty filter 7, motor 8 and silencing apparatus 9, prefilter dust exhaust port 1 links to each other with one-way valve 3 one ends by cryogenic pipe 2, and the other end of one-way valve 3 links to each other with exhaust Venturi tube 5 by high temperature conduit 4, and prefilter dust exhaust port 1 links to each other with the right side of air prefilter 6, described air prefilter 6 links to each other with an end of motor 8 below by empty filter 7, and the other end of motor 8 links to each other with exhaust Venturi tube 5 by silencing apparatus 9.
Described one-way valve 3 is the gas control one-way valve.
Described exhaust Venturi tube 5 is stainless steel exhaust Venturi tube.
The working principle of this embodiment: the engine combustion required air from air prefilter through out-of-date, airborne most of dust is filtered out, and by in the cryogenic pipe and high temperature conduit suction exhaust Venturi tube by the one-way valve place, clean air enters motor and fuel oil mixed combustion after further being filtered by empty filter, the waste gas that the burning back produces is through silencing apparatus, the exhaust Venturi tube of flowing through then, off-gas flows is accelerated at this flow velocity, make to produce low pressure herein, thereby realize waste gas injection dust discharge function.
The beneficial effect of this embodiment is: the utility model, and the reliability height, simple in structure, it is convenient to implement, and not only can realize dust discharge automatically efficiently, also will effectively improve its dust separation effect, prolongs filter core working life.
Specific embodiment of the utility model does not constitute restriction of the present utility model, and every employing analog structure of the present utility model and variation are all in protection domain of the present utility model.
Relational language is explained
1, air prefilter: utilize swirling eddy to produce centrifugal action, the device that the dust separation that particle in the engine charge is relatively large is come out.
