Abstract
The utility model provides a cyclone oil-gas separator with a spiral labyrinth structure, which comprises a conical cavity, wherein a mixed oil gas inlet pipe is arranged on the side wall of the upper part of the conical cavity, an air outlet opening is arranged on the top, and an oil return opening is arranged at the bottom. A spiral labyrinth separation passage is arranged on the inner wall of the conical cavity from top to bottom, the spiral labyrinth separation passage is a convex strip formed on the surface of the inner wall of the conical cavity, and goes downwards in the spiral shape on the inner wall of the conical cavity, and in addition, the spiral labyrinth separation passage is in a discontinuous type. The utility model adopts the conical cavity to be combined with the spiral labyrinth structure, under the condition of adopting the same manufacture process, the wall impacting effect during the oil gas centrifugal rotation can be improved, the oil gas attaching capability can be improved, and the utility model perfectly reduces the mixed gas entering a combustion chamber of an engine, reduces the discharge, and reduces the engine oil consumption.
Description
Technical field
The utility model relates to automobile engine crankshaft case aeration technology field, is specifically related to a kind of cyclone type oil-gas separator.
Background technology
Gasoline engine is in the compression travel process, and the mixed with little amount gas in the cylinder is by piston ring and cylinder interporal lacuna, the ring gap, and the crankcases that bleed such as valve and valve guide bushing gap, major part is the gasoline that does not fire, discharging shows as hydrocarbon.According to the national legislation requirement, this gaseous mixture can not enter atmospheric environment, but if not with its processing, it easily makes machine oil precipitate, and influences the greasy property of machine oil, and a large amount of gaseous mixtures are assembled also can cause the crankcase pressure rising, causes hermetically-sealed construction leakages such as oil sealing.Ventilating system is exactly the importing cylinder combustion that this gaseous mixture is an amount of, under the prerequisite that does not influence performance, handles this gaseous mixture.
Traditional cyclone type oil-gas separator as shown in Figure 4, it adopts single circular cone cavity 1 design, the inner wall smooth of circular cone cavity 1 utilizes the rotary centrifugal force of gas that oil gas is separated.It is to the Oil-gas Separation effect, and the attached wall energy power of oil droplet is less.Therefore, still there is a large amount of oil gas can enter in the gas handling system, causes the valve carbon distribution serious, influence the performance of engine.
Summary of the invention
The utility model proposes a kind of cyclone type oil-gas separator with spiral labyrinth structure at the deficiency that prior art exists, and adopts the circular cone cavity in conjunction with the spirality labyrinth structure, has improved the separating effect of oil gas.
The technical solution of the utility model is as follows:
A kind of cyclone type oil-gas separator with spiral labyrinth structure, it has the circular cone cavity, is provided with mixed oil and gas and goes into pipe on circular cone cavity upper portion side wall, and exhaust outlet is arranged at the top, and oil return opening is arranged at the bottom.It is characterized in that on described circular cone cavity inner wall, being provided with the spirality labyrinth from top to bottom and separate the road, it is the raised line that is formed on circular cone cavity inner wall surface that the road is separated in described spirality labyrinth, shape is descending in the shape of a spiral on the circular cone cavity inner wall, and to separate the road be discontinuous in the spirality labyrinth.
Further, separate between the road in the spirality labyrinth adjacent in the left and right sides, and be formed with the oil gas data feedback channel from bottom to top along the circular cone cavity inner wall.And described oil gas data feedback channel evenly distributes along the circumferencial direction of circular cone cavity, and the protrusion height that the road is separated in the spirality labyrinth also is to become short from top to bottom gradually.
The utility model adopts the circular cone cavity in conjunction with the spirality labyrinth structure, adopting under the same fabrication process condition, because being set, the spirality labyrinth separates the road structure, improved the rebuffed effect when oil gas is centrifugal to be rotated, can improve the adhesive ability of oil gas, better reduce gaseous mixture and enter in the combustion chamber of engine, reduce discharging, reduce oil consumption.Compare with other similar cyclone type oil gas separation structure, this structure is only separated the road by increase the spirality labyrinth on the awl wall of garden, has just improved the separating property of oil gas, and cost does not almost increase.

Fig. 2 is that traditional cyclone type oil gas separates schematic diagram;
Fig. 3 is the A-A cutaway view of Fig. 2;
The specific embodiment
Fig. 4 is traditional cyclone type oil gas separated structures schematic diagram.
Describe structure of the present utility model in detail below in conjunction with accompanying drawing:
Referring to Fig. 1 and Fig. 2, this cyclone type oil-gas separator includes a circular cone cavity 1, the same with existing similar gs-oil separator, on the upper portion side wall of circular cone cavity 1, be provided with mixed oil and gas and go into pipe 4, exhaust outlet 6 is arranged at the top, oil return opening 5 is arranged at the bottom, and they are all combined by plastics molding process, and whole cyclone type oil-gas separator is connected engine cylinder by bolt and covers.Different is that the inwall of circular cone cavity 1 is not smooth, is provided with the spirality labyrinth from top to bottom and separates road 2 on circular cone cavity 1 inwall, forms the spiral labyrinth structure.Road 2 is separated for being formed on the raised line of circular cone cavity 1 inner wall surface in the spirality labyrinth, shape is descending in the shape of a spiral on circular cone cavity 1 inwall, and to separate road 2 be discontinuous in the spirality labyrinth.
And, the layout that road 2 is separated in the spirality labyrinth also has requirement, referring to Fig. 3, to separate between the road 2 in adjacent spirality labyrinth in the left and right sides, and form oil gas data feedback channel 3 from bottom to top along circular cone cavity 1 inwall, and this oil gas data feedback channel 3 preferably will evenly distribute along the circumferencial direction of circular cone cavity 1.In addition, in order to reach better oil gas separation, the protrusion height that the spirality labyrinth can also be separated road 2 is designed to become gradually short form from top to bottom.
When engine is in running status, the mixed oil and gas 7 of engine crankcase can pass through cylinder body, the cylinder cap blow vent enters valve mechanism cover and goes into pipe 4 inflow cyclone type oil-gas separators by mixed oil and gas, because circular cone cavity 1 separates 2 existence with the spirality labyrinth, mixed oil and gas 7 produces the spiral rotation of oil gas 8 in gs-oil separator, in the rotary course of oil gas 8, separate 2 contact generation oil droplets 9 with the inwall of circular cone cavity 1 and outstanding spirality labyrinth, oil droplet 9 is downwards by in the oil return opening 5 inflow engine oil pans, and the gas 10 after separating then enters to enter in the engine at last in the inlet manifold by exhaust outlet 6 under the guiding of oil gas data feedback channel 3 and burns.
