Abstract

The invention discloses an air filter. The air filter comprises a framework, a filter element, second bolts and first bolts, wherein a first through groove is formed in one side edge of the framework; the filter element is placed into the framework through the first through groove; a plurality of first mounting holes are formed in four edges of an outer plate of the framework and communicated with an inner plate of the framework; a plurality of second mounting holes are formed in the filter element and correspond to the first mounting holes in one edge of the outer plate; the second bolts penetrate part of the first mounting holes and part of the second mounting holes corresponding to the part of the first mounting holes; the first bolts penetrate the rest of first mounting holes. The air filter provided by the invention adopts a split structure, that is, the filter element and the framework can be separated from each other, during regular maintenance and repair of the filter element in normal times, all that is needed is to take out the filter element, so that the maintenance and repair time is shortened, however, in case that the filter element needs to be replaced due to damage and the end of the service life , all that is needed is to replace the filter element, so that the maintenance cost is lowered, and likewise, if the framework is damaged and needs replacement, all that is needed is to replace the framework.

Description

A kind of air cleaner

Technical field

The present invention relates to a kind of air cleaner, relate in particular to a kind of air cleaner of railcar device cooling system.

Background technology

The air cleaner of railcar device cooling system is all-in-one-piece at present, be that filter core and framework are the integral type structure, filter core is the critical component of air cleaner, it is also easily worn part, need at ordinary times filter core is carried out to conventional maintenance and repair, when maintenance and repair, all whole air cleaner to be pulled down together, just can carry out lower step operation, increased the time of maintenance and repair, and, when filter core cut-off in service life or the replacing of damage needs, can only change whole air cleaner, maintenance cost is high.

Summary of the invention

Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of Split type air filter.

Technical solution of the present invention is achieved in that a kind of air cleaner, comprises framework, filter core, the second bolt and the first bolt; One side of described framework has the first groove; Described filter core is placed in framework by the first groove; Four limits of the outside plate of described framework have a plurality of the first installing holes; Described the first installing hole connects the inner panel of framework; Have a plurality of the second installing holes on described filter core; Described the second installing hole is corresponding with outside plate the first installing hole on one side; Described the second bolt is through the first installing hole and the second installing hole corresponding thereto; Described the first bolt is through remaining the first installing hole.

Preferably, the lower side of described framework has the first groove.

Preferably, the lower end of described filter core has a plurality of second installing holes corresponding with the first installing hole.

Preferably, the first installing hole quantity that four limits of the outside plate of described framework have is identical.

Preferably, the outside plate lower end symmetry of described framework has two the second grooves; The first mounting hole site of the following both sides of outside plate of described framework is in the second groove.

Preferably, four limits of the outside plate of described framework respectively have four the first installing holes.

Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:

Air cleaner of the present invention, for split-type structural, filter core can separate with framework, at ordinary times when filter core is carried out to conventional maintenance and repair, only need to take off filter core gets final product, reduced the time of maintenance and repair, and when cut-off in filter core service life or damage while needing to change, also as long as renew cartridge more, reduced maintenance cost, equally, if framework damages while needing to change, also as long as change framework.

The accompanying drawing explanation

Below in conjunction with accompanying drawing, technical solution of the present invention is described further:

The structural representation that accompanying drawing 1 is air cleaner of the present invention;

The cross-sectional schematic that accompanying drawing 2 is air cleaner of the present invention;

Wherein: 1, framework; 2, filter core; 3, the second bolt; 4, the first bolt; 5, the first groove; 6, outside plate; 7, the first installing hole; 8, inner panel; 9; The second installing hole; 10, the second groove.

The specific embodiment

Below in conjunction with accompanying drawing, the present invention is described.

Of the present invention a kind of air cleaner as shown in accompanying

drawing

1,2, comprise framework 1, filter core 2, the second bolt 3 and the first bolt 4; One side of described framework 1 has the first groove 5; Described filter core 2 is placed in framework 1 by the first groove 5; Four limits of the outside plate 6 of described framework 1 have a plurality of the first installing holes 7; Described the first installing hole 6 connects the inner panel 8 of framework 1; Have a plurality of the second installing holes 9 on described filter core 2; Described the second installing hole 9 is corresponding with outside plate 5 the first installing hole 7 on one side; Described the second bolt 3 is through the first installing hole 7 and the second installing hole 9 corresponding thereto; Described the first bolt 4 is through remaining the first installing hole 7.

Concrete, the lower side of framework 1 has the first groove 5; The lower end of described filter core 2 has a plurality of second installing holes 9 corresponding with the first installing hole 7; The first installing hole 7 quantity that four limits of the outside plate 6 of described framework 1 have are identical; The outside plate 6 lower end symmetries of described framework 1 have two the second grooves 10; The first installing hole 7 of the outside plate 6 following both sides of described framework 1 is positioned at the second groove 10.

General, when four limits of the outside plate 6 of described framework 1 respectively have first installing hole 7 of four, use bolt air cleaner to be fixed on to fixed effect the best of railcar equipment.

During installation, at first use 12 the first bolts 4, through the first installing hole 7, framework 1 is fixed on railcar equipment, then filter core 2 is placed in framework 1 by the first groove 5, the second installing hole 9 that the lower end of filter core 2 is had, with after the first installing hole 7 aligns, is used 4 the second bolts 3 that filter core 2 is fixing.Due to the setting of the second groove 10, be positioned at the second bolt 3 of filter core 2 both sides, lower end only through the inner panel 8 of filter core 2 and framework 1, be positioned at outside plate 6 and the inner panel 8 of the second middle bolt 3 of filter core 2 lower ends through filter core 2, framework 1, make the good fixing effect of filter core 2.At ordinary times when filter core 2 is carried out to conventional maintenance and repair, unload 4 the second bolts 3, just can filter core 2 be taken out from the bottom of framework 1, simple to operate, reduced the time of maintenance and repair, and when filter core cut-off in service life or the replacing of damage needs, also, as long as more unload 4 the second bolts 3, just can filter core 2 be taken out from the bottom of framework 1, after the filter core 2 renewed, from the bottom of framework 1, filter core 2 is put into, 4 the second bolts 3 of screwing on get final product, and have reduced maintenance cost, same, if framework 1 damages while needing to change, also as long as change framework 1.

Above-described embodiment is only explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
