Description
Technical field
The utility model relates to deaerator technical field, particularly relates to a kind of diesel engine oil gas separating device.
Background technique
When the deaerator of existing use works, gas mixture enters from the suction port of deaerator lower end, Oil-gas Separation is carried out through a random iron wire group, waste gas after separation is discharged from deaerator air outlet, and machine oil then flow back in engine crankcase from the suction port of deaerator along former road.
The major defect of the deaerator of said structure is that the machine oil after Oil-gas Separation is when relying on gravity again to flow back into crankcase from suction port, the impact of the gas mixture newly entered can be suffered and cause oil return not smooth, and when crankcase pressure reach a certain height, the flow velocity of gas mixture quickly, can directly by the machine oil of backflow together with going out deaerator discharged to air, deaerator air outlet is made outwards to spray machine oil, oil consumption is caused to increase, less economical, environmental pollution is serious simultaneously; In addition, it is smooth that the filtrating equipment of above-mentioned iron wire unity structure is very easy to cause oil gas to discharge because dirt blocking, can cause that crankcase pressure is excessive even causes other engine failure.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of diesel engine oil gas separating device, easily outwards machine oil is sprayed to solve existing deaerator air outlet, large, the less economical and self-filtering structure of fuel consumption is caused easily to block, unserviceable technical problem.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of diesel engine oil gas separating device, comprise deaerator body, described deaerator body is respectively equipped with air outlet and suction port, described air outlet is positioned at the top of described suction port, the bottom of described deaerator body is provided with the return opening be communicated with the crankcase of described diesel engine by return tube, some layers of filter screen are provided with in described deaerator body, every layer of described filter screen is the tubular of upper and lower open at both ends, and all described filter screens are set-located from outside to inside successively, described suction port is towards the outer surface of filter screen described in outermost surface.
As improving further, the oil returning pipe joint preventing the gas mixture in described diesel engine crankcase from flowing directly in described return tube by between described return tube with described diesel engine crankcase is connected.
As improving further, described oil returning pipe joint comprises the oil returning pipe joint body be communicated with described return tube, there is in described oil returning pipe joint body an appearance oil pocket, described oil returning pipe joint body is provided with the flow-off be communicated with described appearance oil pocket, and described flow-off is positioned at the crankcase of described diesel engine.
As improving further, described deaerator body connects a Decompression valves.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
Because this deaerator can realize air inlet, give vent to anger and separately the carrying out of oil return, independent return line design effectively prevent the impact of gas mixture to oil return, the flow velocity of return line and gas mixture and pressure have nothing to do, solve the problem of deaerator air outlet spray machine oil, greatly reduce fuel consumption, economic and practical, energy-conserving and environment-protective; Arranging of multiple filtration net effectively can improve oil-gas separation efficiency, and not easily blocked, operational safety is high, reasonable in design, substantially increases the efficiency of Oil-gas Separation.
Owing to adding pressure-relief valve structure, oil gas can be discharged from Decompression valves, and avoid because the blocking of deaerator filtration causes engine failure, Security is high, uses reliable.
Due to the design of oil returning pipe joint, avoid the gas mixture in crankcase directly to flow out from the return tube of deaerator, the problem lost efficacy about making the separation of deaerator, structure is simple, highly versatile.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1 to Fig. 5 jointly shown in, a kind of diesel engine oil gas separating device, comprise deaerator body 1, deaerator body 1 is respectively equipped with air outlet 4 and suction port 2, air outlet 4 is positioned at the top of suction port 2, the bottom of deaerator body 1 is provided with the return opening 5 be communicated with the crankcase of diesel engine by return tube 6, as shown in fig. 1, return tube 6 is connected with the oil returning pipe joint 7 preventing the gas mixture in diesel engine crankcase from flowing directly in return tube 6 by between diesel engine crankcase.
Oil returning pipe joint 7 can adopt following specific constructive form: as shown in Figure 3, oil returning pipe joint 7 comprises the oil returning pipe joint body 70 be communicated with return tube 6, there is in oil returning pipe joint body 70 an appearance oil pocket 71, oil returning pipe joint body 70 is provided with and the flow-off 72 holding oil pocket 71 and be communicated with, and flow-off 72 is positioned at the crankcase of diesel engine.Wherein, after appearance oil pocket 71 inner engine oil of oil returning pipe joint fills, then flow back in crankcase from flow-off 72, the machine oil held in oil pocket 71 effectively forms and prevents oil gas in crankcase from directly entering the resistance in return tube 6.
As shown in Figure 2, be provided with some layers of filter screen 8 in deaerator body 1, every layer of filter screen 8 is the tubular of upper and lower open at both ends, and all filter screens 8 are set-located from outside to inside successively, and suction port 2 is towards the outer surface of filter screen described in outermost surface 8.
As shown in Figure 5, deaerator body 1 connects a Decompression valves 11.After the filter element of filter screen textural anomaly blocking of deaerator, oil gas can be discharged from Decompression valves 11, avoids the engine failure caused because exhaust is not smooth.
As shown in Figure 4, the working principle of this deaerator is: gas mixture flows out from crankcase ventilation joint 10, enter in the suction tude 3 that is arranged on mounting bracket of oil-gas separator 9, enter in deaerator body 1 from the suction port 2 of deaerator, Oil-gas Separation is realized after the multiple layer metal filter element of filter screen of inside, machine oil after separation relies on gravity to flow back in oil returning pipe joint 7 through the return tube 6 of deaerator after being gathered into and dripping, after machine oil in the appearance oil pocket 71 of i.e. oil returning pipe joint body 70 fills, flow back in crankcase from flow-off 72, waste gas after separation through the air outlet 4 of deaerator discharged to air.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
