Specifically, in this example, a drop of oil is taken as an example for analysis and description:

as shown in fig. 1, when oil drops drop on the first outer oil screen bounding wall 328, the corresponding F1 is the component force of the unit gravity of the oil drops in the left-right inclined direction of the first outer oil screen bounding wall 328; f2 is the component force of unit gravity of oil drops in the front and back inclined directions of the first outer oil screen coaming 328; α is an inclination angle of the first outer oil mesh fence 328 in the left-right direction in a normal installation state, and preferably, α is 13.6 °; beta is an inclination angle of the first outer oil mesh coaming 328 in the front-rear direction in a normal installation state, and preferably, beta is 16 degrees;

F1=mg*sin13.6=0.235， F2=mg*sin16=0.276

and (3) synthesizing the optimal oil drop flow direction force: γ = arctan (F1/F2) =40.4 °, γ is the angle between the flow direction of oil droplets in the first outer oil mesh enclosure 328 and the first side 3271.

The resultant force direction of the oil drops in the first direction and the second direction is the corresponding stress direction of the oil drops on the inclined plane of the first outer oil screen coaming 328, when the oil drops are subjected to force, the stress direction corresponds to the oil drop flowing direction, and when the oil drops drop, the oil drops flow downwards along the inclined plane of the first outer oil screen 320 along the resultant force direction.
