Abstract
The utility model belongs to the technical field of accessories for engineering machinery fuel engines, and discloses an oil-bath type air filter. According to the technical scheme, the oil-bath type air filter is structurally formed by an upper filtration mechanism and a lower filtration mechanism which are fixed to form an integrated structure; the lower filtration mechanism comprises a lower air filtration end cover, a filter element shell, a filter element oil wire and a lower filter element upper baffle, wherein the filter element shell, the filter element oil wire and the lower filter element upper baffle are arranged in the lower air filtration end cover; the lower filter element upper baffle is fixedly connected with the inner side of an upper opening of the filter element shell, the outer side of the upper opening of the filter element shell is provided with an annular groove which is used for fixing an annular sealing ring, a shell of the upper filtration mechanism is clamped onto the sealing ring and fixedly connected with the annular groove. The oil-bath type air filter has the advantages that the oil-bath type air filter is reasonable in structure and good in sealing effect, the filter element oil wire can be replaced at any time, and the service life of the oil-bath type air filter is prolonged.
Description
Technical field
The utility model belongs to and is used in engineering machinery fuel oil engine fittings technical field, relates in particular to a kind of oil bath air cleaner.
Background technique
In the great engineering construction such as mine, expressway, airport, railway, water conservancy and hydropower, the large-scale power mechanical engineerings such as large-scale petrol and diesel oil car, excavator play an important role; In the rugged environment of flying upward at this sudden and violent dirt, air filter forms the umbrella for above-mentioned mechanical fuel motor.The structure of air-strainer is made up of the structure filtering mechanism 1,2 that is fixed as one of upper and lower two-stage as shown in Figure 1, wherein, the lower filtering mechanism in currently available technology as shown in Figure 2 by air filter lower end cap 3, be arranged at filter element shell 4 wherein, filter core silk noil 5 and form with the filter element shell opening lower filter overhead gage 7 that 6 riveteds are connected that turns edge outward.Be exactly the filter core silk noil of riveted in internal structure and affect the parts in its working life as air-strainer; Once this filter core silk noil has been covered with oily dirt, just must change whole air-strainer, this is exactly a kind of waste greatly for other intact parts; In addition, due to above-mentioned riveted construction, the upper filter structure that makes to form filter cleaner is merely able to be pressed together on and on lower filter overhead gage, causes the sealability that forms filter cleaner to be difficult to guarantee.
Model utility content
The purpose of this utility model is just to provide a kind of rational in infrastructure, the oil bath air cleaner that can change at any time silk noil.
The technological scheme that realizes the utility model above-mentioned purpose is:
A kind of oil bath air cleaner, its structure is made up of the upper and lower two-stage structure filtering mechanism that is fixed as one; Wherein said lower filtering mechanism comprises air filter lower end cap, is arranged at filter element shell, filter core silk noil, lower filter overhead gage wherein; Between described lower filter overhead gage and described filter element shell upper shed inner side, be fixedly connected with, described filter element shell upper shed arranged outside is useful on the annular groove of stationary annular seal ring, the housing of described upper filter structure is stuck on seal ring, and is fixedly connected with described annular groove.
The additional technical feature that forms above-mentioned a kind of oil bath air cleaner also comprises:
---described filter element shell upper shed inner side is provided with the fixture block of protrusion, between described lower filter overhead gage and above-mentioned fixture block for buckle is fixedly connected with;
---described filter element shell upper shed inner side is provided with screw socket, between described lower filter overhead gage and above-mentioned fixture block for spiral is fixedly connected with;
---between the housing of described upper filter structure and the annular groove of described filter element shell upper shed arranged outside for buckle is connected.
A kind of oil bath air cleaner provided by the utility model compared with prior art has the following advantages: one, due to form the lower filter overhead gage of this oil bath air cleaner with inside described filter element shell upper shed between be fixedly connected with for buckle or spiral, therefore when filter core silk noil can be passed through the dismounting of lower filter overhead gage in the time need to changing, just can realize smooth replacing, effective use of this air filter miscellaneous part can be conducive to form, user cost can be greatly saved; They are two years old, owing to being useful on the annular groove of stationary annular seal ring in filter element shell upper shed arranged outside, the housing of filter structure is stuck on seal ring, therefore can realize air-strainer effective sealing, can effectively prevent the excessive of the interior oil gas of filter cleaner, be conducive to clean environment.
Accompanying drawing explanation
Fig. 1: be the axial cross section structural representation of oil bath air cleaner;
Fig. 2: for forming the axial cross section structural representation of upper and lower two-stage filtering mechanism junction of oil bath air cleaner of the prior art;
Fig. 3: the axial cross section structural representation of the upper and lower two-stage filtering mechanism junction of the oil bath air cleaner providing for the utility model.
Embodiment
Oil bath air cleaner the utility model being proposed below in conjunction with accompanying drawing is described in further detail:
Be illustrated in figure 3 the axial cross section structural representation of the upper and lower two-stage filtering mechanism junction of the oil bath air cleaner that the utility model provides.The structure of this oil bath air cleaner is made up of the upper and lower two-stage structure filtering mechanism 1,2 that is fixed as one; Wherein, lower filtering mechanism comprises air filter lower end cap 3, is arranged at filter element shell 4, filter core silk noil 5 and lower filter overhead gage 7 wherein; Be provided with the fixture block 8 of protrusion in above-mentioned filter element shell upper shed inner side, between lower filter overhead gage 7 and above-mentioned fixture block 8, realize buckle and be fixedly connected with; Have annular groove 9 in filter element shell upper shed arranged outside, fixing by O-ring seal 10 in this groove, the housing 11 of upper filter structure be stuck on seal ring and with state annular groove by the mode of the clamping structure that is connected to one.
In the structure of above-mentioned oil bath air cleaner, be provided with screw socket 12 in above-mentioned filter element shell upper shed inner side, between lower filter overhead gage and above-mentioned screw socket for spiral is fixedly connected with.
