The inner wall of each separation disc 7 is provided with radially extending ribs 701, each rib 701 extending from the centre of the inner wall of the separation disc 7 to the outer edge of the inner wall of the separation disc 7. The rib 701 protrudes against the inner wall of the separation disc 7. Each separation disc 7 is provided with an inlet aperture near the rotation axis 6 for the entry of the oil mist mixture between adjacent separation discs 7.
When the rotor member rotates, the oil mist mixed gas enters between each adjacent separation discs 7 through the inlet holes, and is separated into oil and clean gas by the rotating separation discs 7, and the clean gas moves upward and is discharged through the second outlet 102. The oil is thrown by the separating disc 7 to the inner wall of the housing 1, flows downwards along the inner wall of the housing 1 and is converged into the suction channel via the diversion holes 501 and is sent to the bearing 3.
Specifically, when the rotor member rotates, the oil mist mixed gas is drawn between each adjacent separation disc 7 and moves laterally toward the inner wall of the casing 1, and the friction force exerted on the oil mist mixed gas by the rib 411 of the separation disc 401 and the inner wall surface of the separation disc 401 imparts lateral movement to the oil mist mixed gas, so that the oil mist mixed gas moves to the outer edge of the separation disc 7 and simultaneously rotates, and oil is collected at the periphery of the separation disc 7 to form larger oil drops and then is thrown to the inner wall of the casing 1.
Referring to fig. 7-8, the gas-liquid separator further includes an impeller 8 and a nozzle 9, the impeller 8 being disposed outside the housing 1.

Specifically, the impeller 8 according to the present embodiment is a conventional impeller in the art, the impeller 8 has a plurality of vanes 801 spaced uniformly along the periphery thereof, and the nozzle 9 sprays oil toward the impeller 8 to generate a jet in a tangential direction of a circle passing through the plurality of vanes 801, thereby rotating the impeller 8 to drive the rotation shaft 6 to rotate.
The working principle of the bearing splash preventing structure of the embodiment is further described below with reference to the structure of the gas-liquid separator:
the nozzle 9 directs a jet of oil to the impeller 8 such that the impeller 8 rotates to rotate the rotatable shaft 6, thereby rotating the separation assembly such that the oil mist mixture is drawn into between adjacent separation discs 7 via the inlet openings to be separated, the separated oil is thrown against the inner wall of the housing 1, and the separated gas is discharged upwardly via the second outlet 102.
The oil is thrown to the inner wall of the shell 1, flows downwards to the bearing seat 2 at the first outlet 101 along the inner wall of the shell 1, and because the rotation of the rotating shaft 6 causes the stop piece 4 to rotate, the oil moves to the inner guide surface 503 of the guide piece 5 along the outer guide surface 201 of the bearing seat 2, enters the suction channel through the guide hole 501, flows outwards to the guide ring 502 under the action of the suction channel, flows to the bearing 3 along the guide ring 502, flows to the gap between the impeller 8 and the bearing seat 2 through the gap of the bearing 3, flows to the oil drain pipe 10, and is discharged to the engine through the oil drain pipe 10. During this process, the oil splashed on the bearing 3 is blocked by the stopper 4 so as not to enter the housing 1. Referring to fig. 2-3, the shape of the bearing seat 2 is adapted to the arrangement positions and shapes of the stop member 4, the guide member 5 and the bearing 3, and a gap is formed between the bottom end of the stop member 4 and the bearing seat 2, so that oil can flow to the bearing 3.
