Preferably, the material that the filter core uses is resin treatment micropore filter paper.

Preferably, top is fixedly connected with pressure-bearing arch cover on the right side of the U-shaped casing, and the pressure-bearing arch cover lower right is set Two connecting plates put are fixedly connected on the right side of U-shaped casing on outer surface, and the air filter exhaust outlet is opened in two connecting plates Between.

3. advantageous effect

Compared with the prior art, the utility model has the advantage of：

（1）The utility model contains the more gas warp of dust granule by the cyclone separator A of setting and air filter B Cross cyclone separator A, a big chunk dust granule can be filtered out, make by L-type exhaust pipe and to feed channel air compared with To be clean, the air just handled is using filter core, and filter element filtering falls very small part dust granule and air can be made clean, Adopting in manner just described, reduces the exposure of filter core and dust granule, so as to solve in the more production of dust granule The problem of air filter service life shortens in institute.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model；The technical scheme in the embodiment of the utility model is carried out Clearly and completely describe；Obviously；The described embodiments are only a part of the embodiments of the utility model；Rather than whole Embodiment.Based on the embodiment in the utility model；Those of ordinary skill in the art are without making creative work All other embodiments obtained；It shall fall within the protection scope of the present invention.

- 4 are please referred to Fig.1, the air filter with cyclone separator, including cylinder 3, cone 4 and ash bucket 6,3 lower section of cylinder is logical It crosses cone 4 and is fixedly connected with ash bucket 6,3 left upper end of cylinder is communicated with air inlet pipe 1, and 1 left end of air inlet pipe is fixedly connected with exhaust fan 2, The vertical portion of L-type exhaust pipe 7 is fixedly connected with inside cylinder 3,4 bottom end of cone offers dust-exhausting port 5, and dust-exhausting port 5 Positioned at the surface of ash bucket 6, the horizontal component of L-type exhaust pipe 7 to feed channel 8 by being communicated with air filter air inlet pipe 9, air filter The right end of air inlet pipe 9 is communicated with U-shaped casing 10, and U-shaped casing 10 is internally connected with filter core 14, and U-shaped 10 right side opening of casing is equipped with sky Filter exhaust outlet 13, exhaust fan 2 are internally connected with power supply.

The material that filter core 14 uses is resin treatment micropore filter paper.

U-shaped 10 right side top of casing is fixedly connected with pressure-bearing arch cover 11, two of the setting of 11 lower right of pressure-bearing arch cover Connecting plate 12 is fixedly connected on U-shaped 10 right side outer surface of casing, and air filter exhaust outlet 13 is opened between two connecting plates 12.

Operation principle：The first step installs various components；Second step, starts exhaust fan 2, exhaust fan 2 contain compared with The gas of more dust granules 15 is extracted into cylinder 3, and air-flow becomes circular motion from moving along a straight line, that is, becomes outer vortex 16, outer whirlpool Revolve 16 air-flows the overwhelming majority along cylinder inboard wall twist downwardly toward cone 4,15 particle of dust granule is in the work of centrifugal force It under, is thrown on cylinder 3 and the inner wall of cone 4,15 particle of dust granule is once contacted with the inner wall of cylinder 3 and cone 4, just Inertia force is lost, is fallen along cylinder 3 and the inner wall of cone 4, is reached up to dust-exhausting port 5, eventually fall into ash bucket 6, is rotated 16 air-flow of outer vortex declined constantly flows into the central part of cone 4 during decline, forms centripetal inside vortex 17 Air-flow, 17 air-flow of inside vortex with it is outer be vortexed 16 air-flows direction of rotation it is identical, the dusty gas by primary treatment is by interior whirlpool 17 air-flows are revolved to be brought into L-type exhaust pipe 7；Third walks, and the dusty gas by primary treatment to feed channel 8 by entering sky Filter air inlet pipe 9, then the inside of casing 10 is entered by air filter air inlet pipe 9, under the air pressure constantly blasted, enter Into filter core 14, after the filtering of filter core 14, it is drained into the cylinder of engine by air filter exhaust outlet 13.

It is described above；The only preferable specific embodiment of the utility model；But the scope of protection of the utility model is not It is confined to this；In the technical scope that any one skilled in the art discloses in the utility model；According to this practicality Novel technical solution and its improvement design is subject to equivalent substitution or change；It should all cover in the scope of protection of the utility model It is interior.
