Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
Embodiment one
Fig. 3 is the empty filter embodiment's of the utility model oil bath a plan view, and Fig. 4 is the empty filter embodiment's of the utility model oil bath a left view.The empty filter of the oil bath of present embodiment can be applied to heavily stick into the gas system.As shown in Figure 3 and Figure 4, this oil bath air filter can comprise housing 11, oil sump 12, and oil sump 12 is connected the below of housing 11.
In the present embodiment, end cap is provided with positioning spigot 17, and this positioning spigot 17 can be circle, is specifically as follows on the upper end cap 21 that is welded in the filter end lid; Safe filter core 16 fixes at positioning spigot 17 places, positions by this positioning spigot 17.By positioning spigot 17 is set on end cap, with respect to the solid mode in the direct top of prior art, can realize better fixedlying positioning of safe filter core 16, make that this place's sealability is better, thereby can carry out more effective filtration gas.
In the present embodiment, also further reduced the size of the filter opening on main filter core 15 and the safe filter core 16 with respect to prior art; For example, 50 microns of the main filter core average pore sizes in the present embodiment, safe filter core is 105 microns of average pore sizes.With respect to prior art, main filter core of the prior art aperture is 60 microns, safe filter core is a nonwoven fabric construct, reduced the size of main filter core filter opening in the present embodiment, and safe filter core unification is the papery state, and its aperture is set to 105 microns, can carry out more effective filtration to gas, improves filtering efficiency.
In the present embodiment, oil sump 12 can be the cylindrical tube shape oil sump, makes more compact structure to reduce installing space; And the cylindrical tube shape oil sump can be saved the space, atmosphere attractive in appearance.The inside of housing 11 is provided with filter screen, and described filter screen is positioned at the top of oil sump 12.Concrete, this filter screen can comprise upper filter screen 18 and lower filter screen 19, wherein, the gas after coming out in the machine oil from oil sump 12 can pass through lower filter screen 19 and upper filter screen 18 successively, by these two filter screens gas is further filtered.Upper filter screen 18 and lower filter screen 19 can be braid fabric.
Below the working principle of the empty filter of the oil bath of present embodiment is described, this sky filter can carry out following three-stage filtration process for air-flow:
Shown in the arrow among Fig. 3, this arrow represent for air-flow move towards the signal.Outside air enters this sky filter by suction port 13, and indrawn air is straight downwards to the oil sump in the oil sump 12, enters behind the housing bump pasta 20 earlier.Then, airflow direction changes 180 °, just between the airflow direction mutation period, dust in air is most of can be brought in the oil sump of oil sump 12 because of inertia, most of dust is adsorbed by machine oil, and is collected and is deposited at the bottom of the pond, and this process is that the one-level of this sky filter is filtered.
Can be after airflow direction changes upwards through lower filter screen 19 and upper filter screen 18.Because the air impact oil sump, splash small amount of engine oil, oil droplet appears in the air, contain the slit of the above-mentioned wire filter core of the airflow passes of mist of oil, dust is adsorbed by the oil film of screen surface.Continuous moistening final formation oil droplet.After isolated oil droplet gathers to a certain degree, can make finally that the dust on the filter screen is rinsed, return oil sump, reduce oil shortage ratio, make oil shortage ratio≤2mg/m
3, and form circulating oil path, strengthened filtering usefulness.This process is the cascade filtration of this sky filter.Wherein, the wire filter core is dirty, does not need to change accessory, and filter core just can recover reset condition through behind the cleaning maintenance, is not afraid of oil smoke.
The air communication of process cascade filtration is crossed the main filter core 15 and the safe filter core 16 of 14 positions, air outlet, by further fine filtering, just can enter motor by air outlet 14 then.And because end caps is provided with positioning spigot 17, this place's sealability is better, prevents gas leakage.And the filter opening size of main filter core 15 and safe filter core 16 reduces, and also can strengthen the filtering effect for air-flow, makes that the gas after filtering cleans more.Whole filtering intake process finishes.Owing to adopted above-mentioned three-stage filtration, the air that enters motor will clean more.
The empty filter of the oil bath of present embodiment, by positioning spigot being set in the air outlet end caps, improved should the sky filter sealing, can better stop sand and dust, reduced the resistance of gas handling system, can be so that filtering efficiency 〉=99.8%, guaranteed should the sky filter filtering efficiency be higher than the empty filter of prior art, the working life of having improved empty filter.Reduced the work load that the dedusting of frequent dismounting filter core brings under the high dusty circumstances, grind hidden danger the morning of having eliminated motor, prolonged the working life of motor greatly, more can satisfy the user demand of heavy engineering car, under abominable applying working condition such as mining area, the filtering efficiency height uses more reliably, maintains more convenient.
Embodiment two
Embodiment of the present utility model also provides a kind of automobile, this automobile comprises the empty filter of the described oil bath of the utility model any embodiment, the suction port of the empty filter of this oil bath is connected with gas handling system, and the air outlet of the empty filter of described oil bath is connected with engine chamber.
Wherein, gas handling system can flow high-order gas handling system for bispin, and bispin flows high-order intake duct and has the Twin channel eddy flow, after the air of eddy flow enters the empty filter of oil bath, the air swirl diffusion area is big, can improve air inlet filtering effect better to sucking the performance filtering effect of dust, sandstone.By flowing high-order gas handling system coupling with bispin, can be so that intake resistance to be less relatively, hidden danger is ground in the more effective performance of engine power the morning of more effective elimination motor.
The automobile of present embodiment, by adopting the empty filter of the described oil bath of the utility model any embodiment, effectively eliminate the generation of grinding serious accidents such as hidden danger, scuffing of cylinder bore morning of motor, prolonged the working life of motor greatly, more can satisfy the user demand of heavy engineering car air inlet filtering.The area big at dust storm has more clear superiority.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment's technological scheme of the utility model.
