Description

Air cleanness filter and assembly thereof

Technical field

The present invention relates to a kind of air intake filtration technology, be particularly related to a kind of engine air cleaning and filtering and assembly thereof, be applicable to that Motor Vehicle, agricultural equipment, gas turbine engine systems, construction equipment, power generating equipment and combustion furnace etc. need to remove in the occasion and equipment of air plankton, also be applicable to the filtration of media such as convection cell.

Background technique

The conventional air-strainer that uses all is to make through folding with filter paper, knuckle place phenomenon of rupture often occurs, and when laying dust, pressure reduction increases very fast. flow resistance increases after meeting water, impels the life-span to shorten.And the grit that captures of filter paper and ash content is stifled is clipped in the crease of filter paper, the utmost point is easy-clear not, because the normal phase silting of dirt ash makes the filter paper breakage, cause automobile, construction equipment, generator set, particularly in the desert, the Gobi desert equipment attrition is more serious, it is frequent to change cylinder sleeve, piston, piston ring, directly and indirect economic loss serious.Also exist fibrous structure loose, porosity is big, easily layering, and fragility is big, intensity difference, air permeability is big, and is non-watertight, feels like jelly behind the chance water, dries the back distortion, easily goes mouldy and comes unstuck, and can not continue to use, and needs the frequent air cleaner cartridge of changing.

Summary of the invention

For a change the existing a series of defectives of above-mentioned conventional art the invention provides a kind of air cleanness filter, particularly engine air cleaning and filtering and assembly thereof.This air cleanness filter can instead clean, and also can clean with water and scrub, and each anti-back filtering effect recovery capability of cleaning reaches more than 97%, can clean repeatedly for a long time and use.

According to above-mentioned purpose, a kind of air cleanness filter and assembly structure thereof, form with filter core and frame common structure, wherein: described filter core is made up of skeleton and diaphragm two-part, comprise that with cylindrical spiral supporting spring be supporting mass, end device filter core head at support spring, and in the other end device filter core termination capping of support spring, and at the outside of support spring axial evenly layout one all struts, strut encloses grid between filter core head and the capping of filter core termination with support spring, and install respectively in the prefabricated device hole of filter core head and the capping of filter core termination the termination at strut two ends, made frame of filter element after the termination fixation with the strut two ends, at the formed enough thick filter membrane diaphragms of grid outer surface device that enclose of strut, both structural group had been synthesized the filter membrane filter core again; Described frame is made up of two-part up and down, wherein the frame bottom is a tube structure, an end welded on head below cylindrical shell, attaching inlet pipe connection on heat exchanger head again, hold mouthful flange plate of place's device band groove level with both hands at cylindrical shell, all screws evenly distribute around the groove flange plate, groove flange plate inner groovy is installed the edge of filter core head, when the edge of filter core head is installed, each pad of the lower plane at plane and edge is put a seal ring sealing on the edge, described frame top is an end socket lid, at the top attaching of the end socket lid connecting tube of giving vent to anger, be with the flange plate of boss in the front end weldering system of end socket lid, the even all open-works that distribute around the boss flange plate, when filter core was installed, the boss of boss flange plate was pressed together on the seal ring that the plane pad is put on the filter core edge, with bolt end socket lid and casing cylinder are linked into an integrated entity, structure becomes the air cleanness filter assembly again.

Filter core encloses the filter membrane diaphragm of grid outer surface device, can make filter membrane filter core diaphragm with the method coiling successively that cellosilk or fibre tow twine, and also can enclose grid outer surface parcel strip or sheet filter membrane diaphragm at filter core.

Described filter core has versatility, can be installed in the filter of middle various types, in air-strainer, combustion gas filter cleaner, oil filter, fuel filter, air-conditioning filter cleaner.

The one or more filter cores of described shell physical efficiency dressing.

The metal manufacturing of described frame of filter element and frame thereof, its optimal material are stainless steel.

Embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:

As Fig. 1---shown in Figure 3, air cleanness filter of the present invention and assembly thereof comprise filter core 10 and can be installed in the frame 20 of filter core 10, wherein: described filter core 10 is supporting mass with the cylindrical spiral supporting spring 1 of middle device, holding an end device filter core head 2 of spring 1, and in the other end device filter core termination capping 3 of support spring 1, and at the outside of support spring 1 axial evenly layout one all struts 7, strut 7 support spring 1 is enclosed grid between filter core head 2 and filter core termination capping 3 in, install respectively in the prefabricated device hole 14 of filter core head 2 and the capping of filter core termination 3 termination 6 at strut 7 two ends, made frame of filter element 15 after termination 6 fixations with strut 7 two ends, install enough thick filter membrane diaphragm 4 at the strut 7 formed grid outer surfaces 25 that enclose again, structural group has been synthesized filter core 10; Described frame 20 is made up of two-part up and down, wherein frame 20 bottoms are cylindrical shell 11 structures, end weldering lower seal head 12 processed below cylindrical shell 11, attaching inlet pipe connection 8 on the heat exchanger head of lower seal head 12 again, be used for connecting air inlet pipeline, hold mouthful 23 place's device groove flange plate 24 level with both hands at cylindrical shell 11, all screws 26 evenly distribute on the peripheral flange face of groove flange plate 24, the edge 5 of filter core head 2 is installed in groove flange plate 24 inner groovies 27, when the edge 5 of filter core head 2 is installed, plane 28 pads are put upper gasket 22 on edge 5, pad deposits packing ring 21 in inner groovy 27, and the lower plane 29 at edge 5 be pressed together on lower gasket 21 that inner groovy 27 pad puts above, realization is to the sealing of filter core 10, described frame 20 tops are end socket lids 13, give vent to anger connecting tube 9 for being connected to outlet pipe in the top attaching of end socket lid 13, front end weldering boss flange plate 17 processed at end socket lid 13, all open-works 18 evenly distribute around the boss flange plate 17, when filter core 10 is installed, the boss position 19 of boss flange plate 17 is pressed together on the upper gasket 22 that the plane pad is put on the filter core edge 5, with bolt 16 end socket lid 13 and casing cylinder 11 are linked into an integrated entity, structure becomes the air cleanness filter assembly again.
