Abstract
The utility model discloses a diesel engine breathing machine system which comprises an oil-gas separation device, a breathing machine gas inlet communicated with the oil-gas separation device, a breathing machine gas outlet communicated with the oil-gas separation device, and a breathing machine oil returning port communicated with the oil-gas separation device. A filter device is arranged in the oil-gas separation device. Accordingly, on the basis that an original centrifugal force separation function is kept, a filter oil-gas function is added, a plurality of filter screens are added in the oil-gas separation device, so that waste gas which is guided in is subjected to oil-gas separation through centrifugal force and is subjected to filter separation by layer-by-layer filtering, and oil-gas separation effect is greatly improved. For example, when gas is collected at the breathing machine gas outlet for detecting, obvious oil trace cannot be detected.

Background technique
In the prior art, the respirator system of diesel engine using is that the waste gas that will reveal in engine cylinder-body imports plug-in resuscitation apparatus by cyclinder head cover.Oil gas tangentially enters along resuscitation apparatus, makes oil gas along the rotation of resuscitation apparatus inwall, relies on centrifugal force that oil is separated with gas, and the oil after separation imports oil sump, and the gas after separation imports suction tude, reaches oil gas separation.
As shown in Figure 1, the respirator system of prior art comprises gas and oil separating plant 103, the resuscitation apparatus suction port 101 that is communicated with gas and oil separating plant 103 is positioned at the resuscitation apparatus air outlet 102 of gas and oil separating plant 103 tops and the resuscitation apparatus oil return interface 104 that is positioned at gas and oil separating plant 103 belows.
Referring to Fig. 1, center enters and represents the mix waste gas trend with the flow direction that arrow a indicates from resuscitation apparatus suction port 101, bottom place discharges and represents the oil component trend with the flow direction of arrow c indication from resuscitation apparatus oil return interface 104 downwards, and the place, top 102 discharges and represents the gas componant trend with the flow direction of arrow b indication from the resuscitation apparatus air outlet to the right.
By making oil gas along the inwall rotation of segregating unit 103, can realize by means of centrifugation the separation of oil gas.But the degree of Oil-gas Separation is not ideal.102 when collecting gases and detecting in the resuscitation apparatus air outlet, obvious oil trace can be detected.
Therefore, wish a kind of novel Diesel Engine Breather system and further improve oil gas separation.
The model utility content
The purpose of this utility model is to provide a kind of novel Diesel Engine Breather system further to improve oil gas separation.
For achieving the above object, the utility model provides a kind of Diesel Engine Breather system, and described Diesel Engine Breather system comprises: gas and oil separating plant; The resuscitation apparatus suction port that is communicated with gas and oil separating plant; The resuscitation apparatus air outlet that is communicated with described gas and oil separating plant; And the resuscitation apparatus oil return interface that is communicated with described gas and oil separating plant, wherein, be provided with filtrating equipment in described gas and oil separating plant.
That is to say, Diesel Engine Breather of the present utility model system is on the basis that keeps original centrifugal force separate function, increase the filter oil airway dysfunction, increase number metafiltration net in plug-in resuscitation apparatus, make the waste gas that is imported on the one hand by the centrifugal force Oil-gas Separation, through filtering layer by layer filtering separation, increased greatly oil gas separation on the one hand.For example, when resuscitation apparatus air outlet collection gas detects, can't detect obvious oil trace, or significantly better than the testing result under the prior art condition.
Preferably, described resuscitation apparatus oil return interface is positioned at below described gas and oil separating plant.
Preferably, described resuscitation apparatus air outlet is positioned at the top of described gas and oil separating plant.
Preferably, described resuscitation apparatus air outlet up.
Preferably, described filtrating equipment comprises multistorey strainer mesh.

Embodiment
For purpose, technological scheme and advantage that the utility model is implemented is clearer, below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is further described in more detail.In the accompanying drawings, same or similar label represents same or similar element or the element with identical or similar functions from start to finish.Described embodiment is the utility model part embodiment, rather than whole embodiments.Be exemplary below by the embodiment who is described with reference to the drawings, be intended to for explanation the utility model, and can not be interpreted as restriction of the present utility model.Based on the embodiment in the utility model; those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, and the scope that all belongs to the utility model protection is elaborated to embodiment of the present utility model below in conjunction with accompanying drawing.
in description of the present utility model, it will be appreciated that, term " " center ", " vertically ", " laterally ", " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", orientation or the position relationship of indications such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, rather than device or the element of indication or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as the restriction to the utility model protection domain.
Fig. 2 is the structural representation according to the utility model one embodiment's Diesel Engine Breather system.Shown in Figure 2 Diesel Engine Breather system comprises gas and oil separating plant 203, the resuscitation apparatus suction port 201 that is communicated with gas and oil separating plant 203, be positioned at the resuscitation apparatus air outlet 202 of gas and oil separating plant 203 tops, and the resuscitation apparatus oil return interface 204 that is positioned at gas and oil separating plant 203 belows.
When operation, mix waste gas enters from resuscitation apparatus suction port 201, and is mobile along the flow direction of arrow a indication, enters gas and oil separating plant 203.Mix waste gas carries out Oil-gas Separation in gas and oil separating plant 203 after, oil component flows along arrow c indication, under action of gravitation, discharges from resuscitation apparatus oil return interface 204; And gas componant 202 is discharged along the flow direction of arrow b indication from the resuscitation apparatus air outlet.
