Abstract

A locomotive air filter comprises a filter tube and a tube cover. The upper section of the filter rube is provided with a filter cotton network. The tube wall is provided with a plurality of entrance window holes on the position corresponding to the filter cotton network. The upper end of the filter tube combines with the tube cover. The inner side of the tube wall near the upper and lower end edge of the entrance window holes is provided with inner concave ring groove to be provided with a ring hoop. And when the multi-layer cotton network is placed into the filter tube, the network can be held and fixed by the upper and lower ring hoops and the air entering the window hole from outside can be filtered by the multi-layer filter cotton network. The tube cover is provided and locked outside the filter tube. The lower end of the tube cover can cover the air entrance window hole and leave a ring-shaped air entrance channel therein. The utility model has advantages of small volume, convenient filter cotton dismounting and replacing.

Description

Locomotive air filter

Technical field

The utility model relates to a kind of locomotive air filter.

Background technology

Locomotive air filter is obligato necessity for locomotive, and not only its material is related to airfiltering quality, and it constitutes more direct filter effect and the use that has influence on air, influences the life-span of locomotive engine.

The locomotive air filter of commonly seeing, as Fig. 1, Fig. 2, shown in Figure 3, combine relatively by a base 1 and a loam cake 2, its base 1 respectively is the housing that concaves and contract with loam cake 2, base 1 inside is provided with inlet plenum 11 and discharge chamber 12, inlet plenum 11 is provided with two intake channels, one is to offer an induction opening 13 on the housing of base, it two is the independent side free air diffuser 14 that outwards is communicated with from inlet plenum, inlet plenum ring limit also is formed with costa colpi with sheathed filtration sponge 21, after making inlet air thus sponge 21 filtering after filtration again the outlet sleeve 22 through being located at discharge chamber one end be guided to carburettor or engine chamber.

There is following shortcoming in these structures:

1, forms a confined space because it mutually combines with base and loam cake, in confined space, mark off inlet plenum and discharge chamber again, so, its inlet plenum and the ratio regular meeting of discharge chamber directly have influence on the fluency of air feed, air is supplied with complex structure, needs bigger volume, takies the locomotive space.

2, base and the airtight mode that combines of loam cake are difficult for finding in good time replacing when making in-to-in filtration sponge dirty, influence the air inlet quality.

Summary of the invention

The purpose of this utility model is to provide the locomotive air filter that a kind of volume is little, productive costs is low.

For achieving the above object, the utility model adopts following design plan: a kind of locomotive air filter, it is characterized in that: it is made up of strainer tube and shroud, wherein, strainer tube epimere portion establishes filtering cotton web, its tube wall corresponds to the filtering cotton web position several air inlet window openings is set, and strainer tube upper end combines with shroud, shroud lower edge cover cover strainer tube the part and and the strainer tube tube wall between leave intake channel.

The strainer tube branch has epimere portion and hypomere portion, and epimere portion has than major diameter, and forms tapered neck between the hypomere portion.

Strainer tube epimere portion tube wall inboard respectively is provided with a recessed ring groove to be installed with hoop, so that filtering cotton web is gripped up and down near air inlet window opening upper and lower side place.

Two terminal coilings of hoop form a protrusion back-up ring.

Filtering cotton web is a multiple field.

Shroud is the cup-shaped to an end opening, after the combination of itself and epimere strainer tube, the air intake window escutcheon covered and therebetween leaves the cheek circular shape intake channel.

Advantage of the present utility model:

1, the utility model locomotive air filter is formed owing to it comprises a strainer tube and a shroud, and wherein strainer tube and shroud are the covering type combination, and the cheek circular shape intake channel that air can directly be formed via strainer tube and shroud combination back enter.This shows that the utility model locomotive air filter volume is little, productive costs is low.

2, the utility model locomotive air filter owing to directly form air inlet window opening at the strainer tube tube wall, is provided with the multiple field filtering cotton web in the air inlet window opening, and the multiple field filtering cotton web get directly establish by two hoops folder fixing, conveniently replaced cleaning.

For further understanding aforementioned purpose and architectural feature of the present utility model, attached now with graphic detailed description.

The specific embodiment

The utility model locomotive air filter, as shown in Figure 4, this airfilter 3 comprises that a strainer tube 4 and a shroud 5 form; It is further constructed, please join Fig. 5, as shown in the figure, this strainer tube had epimere portion 41 and hypomere portion 42 in 4 minutes, epimere portion 41 has than major diameter, form tapered neck 43 between itself and the hypomere portion, its tube wall is provided with multiaspect air

inlet window opening

44a, 44b, each face air inlet window opening 44a, 44b is connected or setting at interval, and a recessed ring groove 45 is respectively established near air inlet window opening upper and lower side place in its tube wall inboard, 46 to be installed with

hoop

61,62,

hoop

61,62 two ends are wound into one and protrude back-up ring 63, when making a multiple field filtering cotton web 7 be inserted in strainer tube 4, get and directly be subjected to hoop 61 and following hoop 62 relative clampings, and mat protrusion back-up ring 63 is fixing; This shroud 5 is the cup-shaped to an end opening, itself and strainer tube epimere portion 41 mat screw closures, its lower ends downward is extended air inlet window opening 44a, the 44b that slightly surpasses strainer tube, cover to air inlet window opening 44a, 44b cover being covered, and, these shroud 5 inner edges and and air inlet window opening 44a, 44b between leave cheek circular shape intake channel 51.

During use, as shown in Figure 6, strainer tube hypomere portion 42 is connected to locomotive carburetor air pipe (figure does not show), carburettor produces suction because of the engine effect, is different tube diameters forms tapered neck 43 in cohesive position setting by the epimere portion 41 at strainer tube 4 with hypomere portion 42, promote suction, extraneous air is promptly because of suction, enter through cheek circular shape intake channel 51, pass air inlet window opening 44a, behind the 44b, enter multiple field filtering cotton web 7, filter layer by layer by multiple field filtering cotton web 7 again, reach that airborne impurity filtering is clean, the air of purification enters the locomotive carburettor by strainer tube hypomere portion again and uses.

Hence one can see that, the new construction of this kind locomotive air filter of the present utility model, directly utilize a strainer tube 4 and a shroud 5 in conjunction with after formation form path, overall space can significantly dwindle, and does not take the space of locomotive.

Multiple field filtering cotton web 7 of the present utility model, it can be filter paper or sponge net, and is very convenient when integral body is disassembled, and provides the user to be convenient to clean voluntarily, can not only reduce the consumption of resource, more promotes the maintenance to engine.

In sum, this kind locomotive air filter of the present utility model, really have and make whole downsizing and reduce manufacturing cost, provide filtering cotton web reusable comfort feature, reduce expending of resource, effectively improve the disappearance of the locomotive air filter of commonly seeing, and the regulation in patent law is closed in its not public use, earnestly ask the gift quasi patent, real be moral just.

Need Chen Ming, the above is the preferable specific embodiment of the utility model, if comply with the change that conception of the present utility model is done, and the function of its generation, when not exceeding specification sheets yet and illustrating contained spiritual, all should be in scope of the present utility model.
