Description
Technical field
The utility model relates to technical field of internal combustion engines, especially a kind of engine air filter.
Background technique
Air-strainer is a kind of device of removing granulometric impurity in air, during reciprocating machine (internal-combustion engine, reciprocating compressor etc.) work, if contain the impurity such as dust in air amount just by the wearing and tearing of aggravation part, so air-strainer must be housed.Air-strainer is comprised of filter core and housing two-part conventionally, and its requirement is mainly that filtering efficiency is high, flow resistance is low, can uses and service free continuously the long period.And the air filter of using on existing agricultural equipment Diesel engine is generally two-stage oil bath air filter, its filter core is the wire of winding shaping, filtering efficiency is poor, the wire resistance being wound around is large, affect air inflow, wire easy corrosion as improper in application maintenance simultaneously, corrosion thing falls into air filter, more easily be inhaled into motor, accelerate the wearing and tearing of cylinder sleeve of engine, piston etc.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, the engine air filter of a kind of good filtration effect, long service life is provided.
The utility model solves the technological scheme that its technical problem adopts: a kind of engine air filter, comprise upper casing and the lower casing being fixedly connected with upper casing, described upper casing and lower casing junction be provided with along lower casing circumferential hoop around centrifugal blade window, upper casing outer side surface is circumferentially with at least three for separating of the dedusting window of larger dust particle, lower casing bottom centre is provided with the adapter sleeve being connected with engine air inlet tube, adapter sleeve upper end is connected with the center tracheae that is communicated with upper casing inner chamber, machine oil for the trickle grit of absorbed air leaves lower casing bottom in, laminating center tracheae outer wall is circumferentially with the filter element part that outer upper end face and upper casing inwall fit tightly, the passage between filter element part and lower casing inwall with Air Flow.
Specifically, described lower casing bottom is positioned at adapter sleeve and is provided with screw bracket, from center, upper casing end, is equipped with the standing screw that upper casing is fixedly connected with lower casing, and standing screw lower end is threaded with screw bracket.
For guiding preferably air to screw in lower casing, nearly lower casing outer wall place, described centrifugal blade window inner side has been provided with the screw piece of guide functions.
For improving filtering effect, described filter element part has two-layer filter core, its at the middle and upper levels filter core be thin sponge, lower floor's filter core is thick sponge.
For improving joint sealing effect, between described lower casing and adapter sleeve, be provided with seal ring.
The beneficial effects of the utility model are: the utility model is by dedusting window, machine oil and filter element part three-stage filtration, greatly improved filter cleaner filter efficiency, reduced intake resistance, reduced the premature wear phenomenon of the component such as cylinder sleeve of engine, piston, piston ring, thereby improved motor overall performance and working life.

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of engine air filter as shown in Figure 1, comprises upper casing 1 and the lower casing 2 being fixedly connected with upper casing 1, and lower casing 2 and upper casing 1 all adopt nylon material to make; Lower casing 2 bottoms are provided with screw bracket 4, from upper casing 1 center, end, are equipped with the standing screw 3 that upper casing 1 is fixedly connected with lower casing 2, and standing screw 3 lower ends are threaded with screw bracket 4.
Upper casing 1 outer side surface is circumferentially with four for separating of the dedusting window 6 of larger dust particle, described upper casing 1 and lower casing 2 junctions be provided with along lower casing 1 circumferential hoop around centrifugal blade window 5, centrifugal blade window 5 nearly lower casing 2 outer wall places, inner side have been provided with the screw piece 10 of guide functions, can make like this air sucking from centrifugal blade window 5 form regular helical, more easily dust be thrown away from dedusting window 6.
For improving joint sealing effect, between described lower casing 2 and adapter sleeve 11, be provided with seal ring 12.
Working procedure of the present utility model is as follows: during diesel engine work, air is tangentially sucked at a high speed between the screw piece 10 of centrifugal blade window 5, and first go up then worsened, because gas produces strong eddy current under the guide functions of screw piece 10, final gas enters in upper casing 1 with spiral motion, when air is first gone up then worsened turning with spiral motion, dust particle larger in air is because centrifugal action has little time to turn, just from dedusting window 6, be reversed dedusting with air separation and throw away, reached the initial filter effect superpower to gas one-level; The air of process one-level initial filter is turned downwards, rushes at the machine oil 7 of lower casing 2 bottoms, and then turns upwards, and when the machine oil of lower casing 2 bottoms is blown in air turning, airborne micronic dust particle is adsorbed by machine oil 7 again, has reached the cascade filtration of gas; The air that most of impurity has been filtered is more after filtration in core components 8 after the three-stage filtration of thick, thin two-layer sponge filter core, and cleaned air is entered in motor from the suction tude being connected with lower casing 2 bottom adapter sleeves 11 by center tracheae 9.
The utility model is by dedusting window 6, machine oil 7 and filter element part 8 three-stage filtrations, greatly improved filter cleaner filter efficiency, reduced intake resistance, reduced the premature wear phenomenon of the component such as cylinder sleeve of engine, piston, piston ring, thereby improved motor overall performance and working life.
Above-mentioned mode of execution is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
