In order to solve the problems of the technologies described above; The utility model provides a kind of empty filter of diesel engine, comprising: the whirlwind strainer, be connected in air pipe on the air outlet, lower end of this whirlwind strainer, be located at this air pipe lower end the oil immersed type strainer, be sheathed on fine filtering, coating and the shell of said air pipe and fine filtering and the air outlet that communicates with said fine filtering of being located at this shell upper end portion on the said air pipe.
Said whirlwind strainer comprises: the strainer body covers with the strainer that is sealed and matched in this strainer body upper end.
Said strainer body comprises: annular guide disc, be connected in the inlet air interface that links to each other with the top ports of said air pipe on the center through hole of this annular guide disc; The annular side of annular guide disc is provided with a plurality of inclination guide vanes that are suitable for when air pipe is air-breathing, in said strainer lid, producing whirlwind; The inwall of strainer lid is truncated cone, on the tangent direction of this strainer lid inwall, is provided with the blowdown slit.
The bottom of said air pipe is provided with a plurality of wind guiding blades that the air-flow that is suitable for making in this air pipe blows to said oil immersed type strainer.
Each wind guiding blade is the emanant distribution in center, and said oil immersed type strainer is the food tray that a cross section is W shape; The central part of each wind guiding blade is fixed with one to the bolt that extends below, and this bolt is connected in the center projections portion of said oil immersed type strainer through a damping seal combination pad.And the bottom of this bolt is provided with locking nut.
The technique scheme of the utility model is compared existing technology and had the following advantages: the empty filter in the utility model is made up of one-level whirlwind coarse filtration, secondary oil immersed type coarse filtration and three grades of fine filterings; And oil sump is set in the lower end; Can guarantee that diesel engine in wide wide use speed range, can both obtain efficient filtering effect; This sky filter adopts overall plastic design, energy-saving material-saving, and weight is lighter, and the antivibration ability is higher.
