The utility model discloses simple structure, it is with low costs. The low pressure intracavity of casing under air filter constructs the air admission after filtering, the drawing fan is with the air suction high pressure chest of low pressure intracavity for air in the high pressure chest is intensive, and atmospheric pressure is big, engine start -ups of can normally breathing in, thus the assurance excavator is normally worked.
Description
Technical field
The utility model relates to a kind of air filter for engine, especially a kind of can by filter after air pressure increase the air filter being convenient to engine start, belong to engine fittings technical field.
Background technique
At present, less than 6 tons mini-excavators all adopt naturally aspirated engine, naturally aspirated engine does not have turbosupercharging function, when excavator is on the plateau of height above sea level more than 4500 meters during operation, because of rarefaction of air on plateau, air pressure is low, air filtering core inspiratory dyspnea on motor, often causes motor cannot to strike sparks startup, each start need to remove air filtering core could ato unit, operate very loaded down with trivial details, operating efficiency is low.
Model utility content
The purpose of this utility model be to provide a kind of structure simple, the air pressure after filtering can be increased the electric air prefilter being convenient to engine start again by filtered air.
The utility model is achieved by the following technical programs:
A kind of electric air prefilter, comprises the gentle body booster body of air-filtering mechanism; Air-filtering mechanism comprises upper shell, rotary fluid and Pneumatic rotor, rotary fluid is fixed in upper shell top, rotary fluid comprises connecting base and multiple swirl vane, multiple swirl vane interval tilts to be fixed on connecting base outer circumferential face in the same way, space between multiple swirl vane forms eddy flow groove, multiple swirl vane outer end is fixed in upper shell top inner wall, Pneumatic rotor is arranged in upper shell, be positioned on the downside of rotary fluid, by the coupling shaft of bearings middle side part under rotary fluid in the middle part of Pneumatic rotor; Gas boosting mechanism is arranged on the downside of air-filtering mechanism, gas boosting mechanism comprises lower shell body, link press span, motor and drawing fan, lower shell body upper end is through upper shell bottom base panel, lower shell body top and coupling shaft lower end are connected, link press span is fixedly supported in the middle part of lower shell body, motor is fixed in the middle part of link press span, and drawing fan is arranged on the downside of link press span, and drawing fan input shaft and motor output shaft are connected.
The purpose of this utility model can also be realized further by following technical measures.
Aforesaid electric air prefilter, wherein said upper shell outer circumferential face is provided with side by side multiple axial dust discharge passage.
Aforesaid electric air prefilter, wherein said Pneumatic rotor blade is L shape.
Aforesaid electric air prefilter, wherein said link press span is decussate texture, and lower shell body is separated into the low-pressure cavity of upside and the hyperbaric chamber of downside by link press span, and drawing fan is positioned at hyperbaric chamber.
Aforesaid electric air prefilter, wherein said lower shell body bottom-open forms air outlet.
The utility model structure is simple, and cost is low.When excavator is on plateau during operation, the eddy flow groove of air through between multiple swirl vane forms the eddy current shape gas of High Rotation Speed, swirling eddy impacts the Pneumatic rotor blade in upper shell, make it high speed rotating, like this under Pneumatic rotor blade centrifugal action, dust in air, dirts etc. throw away from the multiple axial dust discharge passage upper shell outer circumferential face, can by air-filtering, air after filtration enters in the low-pressure cavity of lower shell body, meanwhile starting electrical machinery, under driven by motor, drawing fan rotates, drawing fan is by the air intake hyperbaric chamber in low-pressure cavity, make the air in hyperbaric chamber intensive, air pressure is large, air in hyperbaric chamber is finally by the air outlet supply engine of lower shell body, motor can normal suction start, thus ensure that excavator normally works.The utility model need not any operation bidirectional, and operating efficiency is high, and using scope is wide.
Advantage and disadvantage of the present utility model, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
