Description
Technical field
The utility model relates to a kind of deaerator, particularly, relates to a kind of oil-gas separating device for engine.
Background technique
Because machine oil stirs in the mobile and movement parts of engine interior, gas blowby mixes the generation air-fuel mixture under meeting and air and the piston, and the oil gas that produces can be directed to the firing chamber and burn after process deaerator Oil-gas Separation.This just requires deaerator high efficiency machine oil to be separated from oil gas.
Existing deaerator adopts mazy type or vortex type more, the labyrinth type oil-gas separator utilization be the inertial force of object, namely when fuel-air mixture during through the labyrinth, under wall flow, the gas in the mixed gas then enters ventilation system by the labyrinth smoothly droplet in the mixed gas is run into the labyrinth wall and condensed under inertial force after.The separate mode of cyclone type oil-gas separator is similar to mazy type, but the droplet in the mixed gas is to run under centrifugal action behind the wall of deaerator under wall flow.Although two kinds of deaerators of above-mentioned this have advantages of that resistance is little, non-maintaining, also exist the low defective of separation effect.Also have at present the fraction motor to adopt the filer element type deaerator, characteristics are that separation effect is high, resistance is large, but the resistance that also exists filter core is larger, affects the defective of separation effect.
The model utility content
The purpose of this utility model provides a kind of novel gas and oil separating plant for motor, can effectively separate machine oil from oil gas, thereby reduce consumption of lubricating oil, reduces discharging, reduces carbon deposit in the cylinder.
In order to achieve the above object, the utility model provides a kind of oil-gas separating device for engine, and the cylinder head cover that is arranged on cylinder is inner, and wherein, this deaerator comprises deaerator body, coarse filtration plate, fine filtration plate and oil resistant nonwoven fabric swatch; Described deaerator body comprises horizontally disposed strip plat part; The long limit of described plat part is parallel with the gas stream Inbound; Described coarse filtration plate and fine filtration plate be towards the entrance of oil gas, along gas stream Inbound successively being arranged on the described plat part straight up; Be respectively equipped with the oil resistant nonwoven fabric swatch parallel with fine filtration plate with the coarse filtration plate on the plat part at the rear of described coarse filtration plate and fine filtration plate; Place, intermediate portion on described coarse filtration plate and the fine filtration plate is provided with respectively some filter openings, and the porosity ratio of described coarse filtration plate is greater than the porosity ratio of fine filtration plate, and the filter opening number on the coarse filtration plate is also greater than the filter opening number on the fine filtration plate.
Above-mentioned oil-gas separating device for engine, wherein, the filter opening on the described coarse filtration plate wherein is arranged on the radius of central filter opening greater than the radius of the filter opening that is arranged on the outside, thereby can improves the uniformity that oil gas flows.
Above-mentioned oil-gas separating device for engine, wherein, under the plat part place of described oil resistant nonwoven fabric swatch below is provided with respectively wedge shape oil droplet collection channel and is connected this wedge shape oil droplet collection channel and the drainback passage that is connected with this wedge shape oil droplet collection channel.
Above-mentioned oil-gas separating device for engine, wherein, the coarse filtration plate of deaerator, fine filtration plate and deaerator body are integrated in the cylinder head cover cap jointly; Plat part and the cylinder head cover of described deaerator body are fixed, so that this deaerator body and cylinder head cover form a chamber, the top of coarse filtration plate and fine filtration plate also is fixed on the cylinder head cover simultaneously.
Above-mentioned oil-gas separating device for engine, wherein, described deaerator adopts coarse filtration and twice filtration of fine filtering, and the orifice plate porosity ratio of coarse filtration is larger, and the oil gas flow velocity is slower, is mainly used in filtering out larger oil droplet.The porosity of fine filtering orifice plate, the oil gas flow velocity is high, is mainly used in filtering out remaining less oil droplet in the oil gas.Oil gas enters from the entrance of an end, and when passing the filter opening on coarse filtration plate and the fine filtration plate, flow velocity improves, and then impinges upon on the oil resistant nonwoven fabric swatch, and the oil droplet in the oil gas is adsorbed and converges on the oil resistant nonwovens.Then oil droplet flows in the drainback passage along the wedge shape oil droplet collection channel under the oil resistant nonwoven fabric swatch because the self gravitation impact is down dripped.Gas after the separation then flows through from the dual-side of deaerator, is pumped from an other end at last.
The oil-gas separating device for engine that the utility model provides has the following advantages:
1. coarse filtration is combined with fine filtering, and oil-gas separation efficiency can be brought up to more than 95%.
2. coarse filtration and fine filtering and cylinder head cover integrate, and form a modular unit, reduce component volume and number of spare parts.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Such as Fig. 1 ~ shown in Figure 3, the oil-gas separating device for engine that the utility model provides is arranged on cylinder head cover 1 inside of cylinder, and wherein, this deaerator comprises deaerator body 2, coarse filtration plate 3, fine filtration plate 4 and oil resistant nonwoven fabric swatch 5.
Deaerator body 2, coarse filtration plate 3 and fine filtration plate 4 are integrated in the cylinder head cover 1 jointly, and wherein the top of coarse filtration plate 3 and fine filtration plate 4 is fixing with cylinder head cover 1 respectively.
Deaerator body 2 forms a chamber with cylinder head cover 1.This deaerator body 2 comprises horizontally disposed strip plat part 21.The long limit of plat part 21 is parallel with the gas stream Inbound, and this plat part 21 is fixing with cylinder head cover 1.
Be respectively equipped with the oil resistant nonwoven fabric swatch 5 parallel with coarse filtration plate 3 and fine filtration plate 4 on the plat part 21 at coarse filtration plate 3 and the rear of fine filtration plate 4.Under plat part 21 places of oil resistant nonwoven fabric swatch 5 belows are provided with respectively wedge shape oil droplet collection channel 22 and are connected this wedge shape oil droplet collection channel 22 and the drainback passage 23 that is connected with this wedge shape oil droplet collection channel 22.
As shown in Figure 6, the oil-gas separating device for engine that the utility model provides is when work, and oil gas flows to from an end, through flowing out from the other end behind filter plate, the oil resistant nonwoven fabric swatch 5.When oil gas passed the filter opening of coarse filtration plate 3, gas was accelerated, and accelerating impact is on the oil resistant nonwovens, and oil droplet is adsorbed, and then entered in the drainback passage 23 along the wedge shape oil droplet collection channel 22 under the oil resistant nonwoven fabric swatch 5.Gas flows away from dual-side after separating.Filter opening distribution form in the middle of the coarse filtration plate 3 is that mid-diameter is large, and toward diminishing on every side, purpose is in order to improve the oil gas flow uniformity.Through after the coarse filtration, large oil droplet is separated from oil gas to be fallen.When oil gas passed the filter opening of fine filtration plate 4, because this moment, fine filtration plate 4 was less than the porosity ratio of coarse filtration plate 3, so that oil gas is accelerated to is higher, oil gas strikes on the oil resistant nonwovens can separate little oil droplet.
