Description
Technical Field
The utility model relates to an engine technical field, concretely relates to novel rotatory separation of engine oil gas device.
Background
In the combustion process of the engine, high-temperature and high-pressure fuel gas in a cylinder enters a crankcase through a gap between a piston ring and the wall of the cylinder, and the gas blowby phenomenon is generated. Blow-by gas causes excessive pressure in the crankcase, engine oil dilution, etc., and therefore must be discharged from the crankcase. The gas exhausted from the crankcase contains a large amount of oil mist, and if the gas is directly exhausted, the emission of the engine exceeds the standard, and the oil consumption of the engine is overhigh, so that an oil-gas separator is needed to be used for separating oil and gas.
In the prior art, engines have a plurality of oil-gas separation structures, and the purpose is to keep lubricating oil mist in the engine body and reduce the loss of lubricating oil. The structure closest to the invention is that a fixed labyrinth type separation cavity or a foam filter screen is arranged in the cylinder head to prevent oil mist from being discharged along with air. The existing devices have the defects that when the temperature of an engine is overhigh and the oil mist is relatively thick, the oil mist can not be completely solidified into liquid to flow back and is discharged out of a machine body along with air, so that loss and pollution are caused.
SUMMERY OF THE UTILITY MODEL
The utility model provides a novel rotatory separation of engine oil gas device utilizes the effect of centrifugal force to separate, and the separation process is rotatory synchronous with the camshaft, and engine speed is high more, and exhaust impeller centrifugal speed is also big more, and the separation effect is better.
The utility model adopts the following technical scheme:
a novel engine oil-gas rotary separation device comprises a camshaft, a chain wheel, an exhaust impeller, a breather pipe and a cylinder head; the axle center of camshaft is the through-hole, the sprocket is installed the one end of camshaft, and with sprocket coaxial coupling, the sprocket is kept away from install exhaust impeller on one side of camshaft, exhaust impeller can rotate along with the rotation of camshaft, sprocket and exhaust impeller all install inside the cylinder head, the camshaft is kept away from the one end intercommunication of sprocket has the breather pipe, the breather pipe passes the cylinder head makes the mouth of pipe setting of breather pipe be in the cylinder head is outside.
Further, the cylinder head is in a rectangular parallelepiped shape.
Further, the vent pipe is L-shaped.
Further, the exhaust impeller is in the shape of a fan blade.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The oil mist can not be completely solidified into liquid to flow back when the temperature of the engine is overhigh and the oil mist is relatively thick, and the oil mist is discharged out of the engine body along with air, so that the technical problems of loss and pollution are solved.
The utility model provides a novel engine oil-gas rotary separation device, which comprises a camshaft 1, a chain wheel 2, an exhaust impeller 3, a vent pipe 4 and a cylinder head 5; the axle center of camshaft 1 is the through-hole, sprocket 2 is installed camshaft 1's one end, and with 2 coaxial coupling of sprocket, sprocket 2 keeps away from install impeller 3 on one side of camshaft 1, impeller 3 is the flabellum shape, impeller 3 can rotate along with camshaft 1's rotation, camshaft 1, sprocket 2 and impeller 3 are all installed inside cylinder head 5, cylinder head 5 is the cuboid shape, camshaft 1 keeps away from sprocket 2's one end intercommunication has breather pipe 4, breather pipe 4 is L shape, breather pipe 4 passes cylinder head 5 makes the mouth of pipe setting of breather pipe 4 be in cylinder head 5 is outside.
The utility model discloses a working process does: when the engine is operated, the camshaft 1 rotates synchronously with the rotation of the engine, and the exhaust impeller 3 rotates along with the camshaft 1, and the molecular mass of the lubricating oil is larger than that of air, so that the centrifugal force generated by the exhaust impeller 3 throws the oil molecules into the cylinder head 5. Because of light weight, the air can not be thrown out by the exhaust impeller 3 and enters the hole of the camshaft 1, and is discharged out of the engine through the vent pipe 4 communicated with the through hole of the camshaft 1.
The utility model has the advantages that:
(1) the utility model discloses a rotatory separator of oil gas utilizes the effect of centrifugal force to separate, and separation process and camshaft rotation are synchronous, and engine speed is high more, and exhaust impeller centrifugal speed is also big more, and the separation effect is better.
(2) The device has simple structure, low cost and easy manufacture and installation.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
