Embodiment
The empty filter of a kind of combined type, the machine of including is combined in cyclone tube rough filtering device and the filter core fine-filtering device in the sky filter housing, and on the suction port of said empty filter housing, is provided with whirlwind rough filtering device 1; That is to say; In the present embodiment, air through whirlwind rough filtering device one-level coarse filtration, passes through cyclone tube secondary coarse filtration earlier then; At last through the smart filter of filter core, thereby not only air filter efficiency is high and greatly practiced thrift installing space.Below be more detailed structure:
As shown in Figure 1, protecgulum 2 is installed in empty filter housing of common composition on the shell body 4 with bonnet 6, and said empty filter housing is provided with suction port, air outlet and dust exhaust port, and this housing can be circular, square or other shapes.In said empty filter housing, isolating cylinder 3 is installed, the dust collection chamber A that said isolating cylinder 3 is divided into the inner chamber of said empty filter housing the air-inlet cavity that is communicated with said suction port, the filter core chamber that is communicated with said air outlet and is communicated with said dust exhaust port; Cyclone tube 5 is installed in the said air-inlet cavity, and said filter core chamber is equipped with filter core 7, and said cyclone tube 5 is communicated with said air-inlet cavity respectively with filter core chamber and dust collection chamber.
Isolating cylinder 3 comprises a body 32; Said tube body 32 has first end and second end; Said first end and an end cap that is provided with steam outlet pipe 33 are made as one, and said steam outlet pipe 33 is installed on the air outlet of said empty filter housing, and said second end has uncovered structure; The outer surface of said first end is provided with honeycomb duct fixed plate 31, and the outer surface of said second end is provided with dismountable center tube fixed plate 34.
Cyclone tube 5 comprises center tube 51 and the honeycomb duct 52 that is surrounded on said center tube 51 outer circumferential faces, forms annular air-flow path between said honeycomb duct 52 and the center tube 51, is provided with first swirl vane 53 in the said air-flow path.The honeycomb duct 52 of said cyclone tube is installed on the said honeycomb duct fixed plate 31, and the center tube 51 of said cyclone tube is installed on the said center tube fixed plate 34.Cyclone tube 5 is near the suction port of empty filter housing, and the air of entering is preferentially through cyclone tube 5, and air is during through first swirl vane 53; Because action of centrifugal force; Dust is screwed on honeycomb duct 52 walls, under effect of inertia, arrives dust discharge chamber A, clearancen filter body side by side.180 ° of the cleaner air inversions of tube hub get into filter cores 7 through center tube 51.As shown in Figure 2, said cyclone tube 5 has a plurality of and arranges around said filter core, can certainly be to arrange in filter core one side.This axial admission formula cyclone tube has replaced the design of known straight-through type cyclone tube as strainer, has got rid of the hidden danger that the injection dust discharge brings.Axial admission formula cyclone tube is designed to realize that around arranging around the filter core or in the novel structure form that filter core one side is arranged, having adapted to the requirement of the minimum installing space of the empty filter of engineering machinery cyclone tube and filter core organically are combined in the same housing simultaneously.
Filter core 7 is installed in the said tube body 32, and the two ends of said filter core 7 lean sealing respectively and are installed between the end cap of said bonnet 6 and said isolating cylinder.Preferably, filter core 7 adopts PU glue filter core, and this filter core not only seals tight diametrically, on end face, has also played the twin-stage seal action simultaneously, thereby with further more smart filtration of the air after the filtration of two-stage strainer, has reached high filter efficiency.
Whirlwind rough filtering device 1 comprises the eddy flow airscoop shroud 10 and eddy flow air inlet cap 11 that is installed together.Be provided with rotating shaft 15 between eddy flow airscoop shroud 10 and the eddy flow air inlet cap 11, be fixed with fan blade 12 in the said rotating shaft 15, to strengthen the back-out dynamics of dust.Eddy flow air inlet cap 11 is cylindricality, offers dedusting mouth 16 on its sidewall.Said eddy flow airscoop shroud 10 is provided with a plurality of second swirl vanes 14; And its outer edges is provided with the isolation flange 13 of broad; Be " bamboo hat " shape; Isolation flange 13 can prevent to be inhaled into suction port once more from the dust of the dedusting mouth 16 on eddy flow air inlet cap 11 tops, can prevent simultaneously to get into filtrating equipment and damage filter along the rainwater entrained air of eddy flow air inlet cap 11 landings, thereby play rainproof, dustproof effect.What deserves to be mentioned is that as the one-level rough filtering device, air gets into from second swirl vane 14 of eddy flow airscoop shroud 10 bottoms, also has the ran-proof and snow-proof effect.
Working principle is following:
As shown in Figure 1, the order that arrow marked is airfiltering order, and cyclone blade 14 gets into air from the bottom, through the inner fan blade 12 of whirlwind strainer, dust is screwed out from the dedusting mouth 16 on eddy flow air inlet cap 11 tops, and this is first step coarse filtration; Air gets into cyclone tube 5 then, during through built-in first swirl vane 53 of cyclone tube 5, because action of centrifugal force; Dust is screwed on the water conservancy diversion tube wall; After under effect of inertia, arriving dust collection chamber A, discharge empty filter body through dust-exhausting bag 9, this is the second step coarse filtration; 180 ° of the air inversions that each tube hub is cleaner then get into filter cores 7 through center tube 51, and the air after filter core 7 filters the two-stage strainer is further smart again to be filtered, and filter filtration effectiveness and working life thereby reached high coarse filtration filter efficiency with smart.
Generally speaking, this sky filter cyclone tube rough filtering device efficiently organically is combined in the same housing with filter core fine-filtering device efficiently, has solved engineering machinery the difficult problem that the empty filter in desert of larger volume could be realized multistage filtering must be installed.Empty filter of this integrated form sand and dust not only air filter efficiency height but also compact structure has greatly been practiced thrift installing space; Especially rough and careless efficient is greatly improved; Thereby prolonged the working life of filter core; Directly reduced its manufacturing and maintenance cost effectively, the development of other component of automobile industry has also been had far-reaching influence.
